The crusaders and muslims in palestine Essay Example For Students

The crusaders and muslims in palestine Essay Crusaders and Muslims in PalestineThroughout time, history has had a tendency to repeat itself. It has done so in good means as well as bad. People learn from the past and apply it to their every day lives. Although people try to do the right thing and not follow mistakes that have been already made, they just seem to come about. Today, our country is experiencing a situation that is extremely similar to the situation occurred in 11th, 12th, and 13th centuries. Crusades now can be defined as well all wars undertaken in pursuance of a vow and directed against infidels. Back in the middle ages, it was known as any military expedition undertaken by the Christians of Europe. We will write a custom essay on The crusaders and muslims in palestine specifically for you for only $16.38 $13.9/page Order now The history of the crusades is filled with the mercilessness of the crusaders and the kind-heartedness of the Muslims. The Muslims were massacred everywhere the crusaders arrived, while the Christians were treated kindly by the Muslims. The Christians and the Muslims were fighting against one another in order to spread their religion, or end the other. The event leading up to the start of the holy wars was the invasions of the Holy Land, Jerusalem. Jerusalem was a holy site for the Christians as well as the Muslims. For the Christians, it was a sacred place because Jesus was crucified and on the site where his body was placed in a tomb. They built a church of Holy Sepulchure which stands of the hill where Christ was believed to have been crucified, died, buried, and where he rose again. For the Muslims, this place was cared because they believed that the founder of their religion, Muhammad, was able to visit heaven from there. For that reason, they built many masques and the most famous one is the Dome of the Rock. Islam was spreading very fast. Europes greatest threat came from the forces of Islam. These threats became real. Battles broke out and these battles turned to wars that lasted from 1095 to 1229. These years of bloodshed were led by men of power to gain control over the Holy Land of Jerusalem. Jerusalem was extremely important to the Muslims and Christians at this time. Many religious events had happened there, and many of the landmarks of both religions were located in Jerusalem. It was all over for one city, Jerusalem the Holy Land. At first, Christians occupied Jerusalem. The Christian people head out from giving up their land to their invaders, the Muslims. In February of 638, the Christian bishop of Jerusalem, Sophronus, was forced to surrender the city. By the 11th century, the balance of power began to swing toward the West. The Church became more centralized and stronger. Europes population was growing, its urban life was beginning to revive, and both long distance and local trade were gradually increasing. A growing population created more wealth that meant a greater demand from elsewhere. The interests coincided with religious feeling about the Holy Land and so the crusades began. The Muslims treated Christians well at fist. They just thought of them as people who were misguided in their choice of religion. They encouraged them to convert to Islam, but never forced them. The Christians who did not convert were than known as mawali meaning brother of Islam. Those who did not convert were called djimmis meaning the protected people. Even thought the Christian people were able to keep their religion, they had to take certain rules that came along with that. They had to pay extra tax called jizya, as well as having to abide by extra rules such as not being allowed to marry a Muslim, or to own arms or horses. .u9dbae940bccd40b7bc36eeda76c0f41e , .u9dbae940bccd40b7bc36eeda76c0f41e .postImageUrl , .u9dbae940bccd40b7bc36eeda76c0f41e .centered-text-area { min-height: 80px; position: relative; } .u9dbae940bccd40b7bc36eeda76c0f41e , .u9dbae940bccd40b7bc36eeda76c0f41e:hover , .u9dbae940bccd40b7bc36eeda76c0f41e:visited , .u9dbae940bccd40b7bc36eeda76c0f41e:active { border:0!important; } .u9dbae940bccd40b7bc36eeda76c0f41e .clearfix:after { content: ""; display: table; clear: both; } .u9dbae940bccd40b7bc36eeda76c0f41e { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u9dbae940bccd40b7bc36eeda76c0f41e:active , .u9dbae940bccd40b7bc36eeda76c0f41e:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u9dbae940bccd40b7bc36eeda76c0f41e .centered-text-area { width: 100%; position: relative ; } .u9dbae940bccd40b7bc36eeda76c0f41e .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u9dbae940bccd40b7bc36eeda76c0f41e .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u9dbae940bccd40b7bc36eeda76c0f41e .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u9dbae940bccd40b7bc36eeda76c0f41e:hover .ctaButton { background-color: #34495E!important; } .u9dbae940bccd40b7bc36eeda76c0f41e .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u9dbae940bccd40b7bc36eeda76c0f41e .u9dbae940bccd40b7bc36eeda76c0f41e-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u9dbae940bccd40b7bc36eeda76c0f41e:after { content: ""; display: block; clear: both; } READ: Child Labour and in Impoverished Society Essay They were allowed to keep their churches. At this point of time, Europe was in what is known as the Middle Ages of the Dark Ages. This is when the land was separated by manors. All the neighboring manors would be in wars with each other. Each lord was trying to gain more land. Pope Urban II, in a speech of Clermont in France in November 1095, called for a great Christian expedition to free Jerusalem from the Turks, a new Muslim power that had recently begun actively harassing peaceful Christian pilgrims traveling to Jerusalem. Urbans speech appealed to thousands of people of all classes. This started the first crusade. The appeal for soldiers to fight for Jerusalem was very successful. Great nobles, clergy and peasants from all over Europe began preparing for the trip. Most of the people who were going were going for the most important reason, a religious reason. They thought that God had wanted them to. The Crusaders mission was to regain Jerusalem from the holiest ground of the Christian faith from the grasp of the Muslims. The official crusading armies did not head of the long journey until the middle of 1096. There were three main bands from Northern France, Southern France, and Southern Italy. The crusading army arrived in Byzantium over a period of several months early in 1097. Throughout their trip to Palestine, they committed horrible things like raping, murdering, and plundering Jews and Muslims. As they traveled to Jerusalem, they came upon many wars with other Turkish lands as well as lands occupied by Jews. As they marched east, they were joined by thousands of men and even women, ranging from petty knights and their families, to peasants seeking freedom from their ties to the manor. Few people knew what to expect. They all had one goal, to retake the Holy Land. When the Christians finally reached Jerusalem, the crusader army settled down to the business of conducting the siege. Led by priests chanting and holding their sacred relics in front of them, the entire army marched in slow solemn procession barefoot around Jerusalem. Six days after they marched into Jerusalem, the final assault began. More than a day of continuous fighting, the Crusaders forced their way into the city. After almost two months, Jerusalem fell. Crusaders swarmed into the city and killed more than 60.000 Muslim and Jewish inhabitants (Smith, 105). First Crusade was successful and it reinforced the authority of the Church and straightened the self-confidence of Western Europeans. Unfortunately, with victory came new problems. Many Crusaders saw the taking of Jerusalem as the goal; they were ready to go home. To keep the city safe for Christians and prevent Muslims from taking control again many Crusaders stayed behind and established the Christian states just like the ones in West Europe. They hoped to transplant their military. The Christian Knights who went to live in the Middle East found out that the people there had a different way of life. They ate different foods. They dressed in different clothes. The Christians and Muslims were not only living together in the Middle East but also in Spain and Sicily too (Norman, 66). In addition, one of the Crusaders greatest achievements was the opening of the eastern Mediterranean to European shopping. They established trading colonies in Egypt. Eastern connections opened Europe to a brighter understanding of optimistic ways of living and thinking. The biggest difference between Christians and Muslims is religion. Religion has always been a big issue. It always had a big impact on all people and there were many wars fought over the religion. Similarity that I have noticed is that both sides were warriors of God. .u8932e97999db313de077f08b70d2991d , .u8932e97999db313de077f08b70d2991d .postImageUrl , .u8932e97999db313de077f08b70d2991d .centered-text-area { min-height: 80px; position: relative; } .u8932e97999db313de077f08b70d2991d , .u8932e97999db313de077f08b70d2991d:hover , .u8932e97999db313de077f08b70d2991d:visited , .u8932e97999db313de077f08b70d2991d:active { border:0!important; } .u8932e97999db313de077f08b70d2991d .clearfix:after { content: ""; display: table; clear: both; } .u8932e97999db313de077f08b70d2991d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u8932e97999db313de077f08b70d2991d:active , .u8932e97999db313de077f08b70d2991d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u8932e97999db313de077f08b70d2991d .centered-text-area { width: 100%; position: relative ; } .u8932e97999db313de077f08b70d2991d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u8932e97999db313de077f08b70d2991d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u8932e97999db313de077f08b70d2991d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u8932e97999db313de077f08b70d2991d:hover .ctaButton { background-color: #34495E!important; } .u8932e97999db313de077f08b70d2991d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u8932e97999db313de077f08b70d2991d .u8932e97999db313de077f08b70d2991d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u8932e97999db313de077f08b70d2991d:after { content: ""; display: block; clear: both; } READ: Jon Smith Essay Both sides fought for their religion and their beliefs. I do not think that Crusaders made a mistake by going into the war to free Jerusalem because they belong to Jerusalem as much as Muslims do. Neither Christians nor Muslims should forbid each other to be in Jerusalem because that place is very special to both sides. If Jerusalem were so important to both the Muslims and Christians of course, they would fight to keep it or gain control of it. The crusaders achieved the main purpose of the crusades and kept Jerusalem for a while, but the spirit of the people seen before the first crusade took place was never matched again. Later all of the cities taken by the Christians were to be taken back by the MuslimsIn conclusion, the crusades were a very important part of European history that really affects the world. These people fought for what they believed in and, maybe, if they had not fought for what they believed in, we should practice Islam instead of Christianity. Though many people lost their lives and times were tough, balance of power was up for grabs, and it went on for so long, the crusades were fought over the Holy Land to preserve and protect the aspects of each sides religion. The first three crusades show the best, how important they were to everyone and how they could have affected the world today. The First Crusade made people think that is possible for Christian crusaders to control the Middle East. Two hundred years after that, it was clear to them that it was not actually a possibility.

buy custom Classification Systems essay The main significant for undertaking this research is to make a contribution to the scholarly understanding by coming up with a new model and introducing innovative interpretations to this model so as to present a fast and reliable means of data storage and retrieval. The research will not only contribute to the scholars but to business organizations as well. This is because this is the most affected sector since most businesses handle lots of data for their clients and products and services they offer. While most of this data is in unstructured state, most organizations feel that it is not well protected. A lot of this data is sensitive and confidential thus it must be protected using apposite measures. In addition to this, the data should support numerous distribution needs since it is shared across several platforms and between partners and entities as well. The handling and management of unstructured data is documented as one of the chief unsettled problems in the information technology industry (9). This is because; the techniques and equipment that proved successful in handling structured data have proved to be useless when dealing with unstructured data since it is bulky and sophisticated (9). This has consequently created an equally need for equipment and techniques for managing unstructured data that not all governments can afford. Inefficient and irrelevance in search; one of the basic requirements for unstructured data is that it should be searchable. Blumberg Atre (9) argues that before the web came into use, files and documents would be searched using full-text and other search systems. Conversely, with the rapid increase in the use of internet, these searching tools became inefficient enough to serve the highdemand (9). Several research studies have discovered that the standard size for search phrases that are used on communa l webs is only about 1.5-2.5 words. Research has also shown that the standard search contains very few competent Boolean operators, actually less than ten percent of the actual time. With such undersized phrases and very little application of sophisticated search techniques, it is clear evidence that the results are poor or irrelevant. In addition to these, the search machines treat every search application separately. This therefore means that same results are given for a particular search phrase even if the context is different (9). According to Blumberg Atre (9), the inconsistency in methodologies, frameworks and the taxonomies used in organization and classification of data shows that there is no suitable approach for interpreting and modeling unstructured data. Instead on there being one reliable and efficient standard, several models are coming up and each model has its own values and insights. This divergence therefore poses a major problem in the future since it is not certain which model will actual be able to effectively handle the unstructured data. Duplicating computing displays the use of internet and other data extraction systems so as to achieve reliable standards (9). Raghavan (16) classifies data using a two-class classification system using standard queries; the filtering and routing. He asserts that classification is usually general focused and the process with which such classification is performed is called text classification (15). According to Mena (10), unstructured data can best be managed when organized in hierarchical systems commonly referred to as taxonomies. Taxonomy can bee described as a hierarchical structure of classification whereby it moves down from extensive to explicit. This structure acts as a directory on a PC in the sense that it provides an expedient and instinctive way to maneuver and acquire information easily. This therefore means that; instead of formulating a query and then evaluate the results, one can directly access the relevant information by simply formulating queries on the appropriate classes and subclasses. Another advantage with these taxonomies is that they limit the queries to specific classes and sub cla sses (10). A well organized taxonomy may comprise of eighty to ten levels with hundreds or even thousands of classes. The Confidentiality Integrity Availability (CIA) Assurance Model is a commonly used model which recognizes the Confidentiality Integrity and Availability of data as the elementary safety characteristics of information particularly the unstructured data (11). Confidentiality is described as the guarantee of data discretion, the purpose of which is to ensure that only authorized and the intended processes, people or devices can have access to the data (9). This is only achievable when cryptography is implemented. Integrity is the assurance once data is stored, it can not be altered in transition; and the dispatcher of the data must be the person intended to be. To ensure that data is not altered or corrupted on transition, hash algorithms and digital signatures are used (14). Availability is the assurance that data can be accessed by the user in a reliable and timely manner. This guarantees a fast availability of data on request (9). While integrity and availability are maintained, in vaders may cause such information to become less accessible or completely unavailable. Buy custom Classification Systems essay

Medical Marijuana the Alternative Medicine Term Paper

Medical Marijuana the Alternative Medicine - Term Paper Example In line with this, researchers have found that marijuana produces a significant analgesic effect and is effective against weight loss, nausea and vomiting induced by chemotherapy (Kneisl, 2009, 338). However, the use of medical marijuana remains to be the center of debate with regards to legalization. But why should the state legalize the use of marijuana? To give light to the question, there are two categories of marijuana based on its usage, to wit: medical marijuana and recreational marijuana. Medical marijuana refers to marijuana that is used to alleviate undesirable effects of certain medications, treatments, and diseases. Recreational marijuana, on the other hand, refers to marijuana that is used to satisfy personal gratification or to achieve sense of euphoria. Thus, if legalization would be made for the sake of medical right, patients don’t have to endure extreme pain. Aside from usage, there are also two types of marijuana based on leaf appearance and effects. One of them is cannabis sativa. Cannabis sativa leaves are long, thin fingered, and light green. Its buds smell sweet, fruity, and perfumed. Its effect is energetic and uplifting, mostly cerebral. It gives a feeling of optimism and well-being, pain relief, and is hallucinogenic. Unlike sativa, cannabis indica leaves are short, wide fingered and deep green. Its bud is pungent. It gives relaxation, stress relief, and overall body pain relief. It is also used to treat insomnia. Marijuana for the terminally ill is still a debate between right and legality. It is a human right to live free from pain and suffering as well as to make self-determined decisions regarding managing health care in collaboration with the physician (Younts, 2005, 6). The plant exists and widely available, so why not used it to the benefit of those patients? With state regulatory organization, the fear of using marijuana in recreational use might be avoided. If an individual is suffering from a debilitating condition and relief for symptoms is present, we should not deny the right of this individual to choose the right treatment that would ease the discomfort. â€Å"The FDA has approved a drug known as Marinol, which contains THC, the active psychotropic ingredient of Cannabis sativa and a controlled substance, for oral use in treating both loss of appetite due to the AIDS-wasting syndrome and chemotherapy-induced nausea and vomiting† (Cohen, 2006, 20). Likewise, the marijuana also contains the same compound THC. The only difference is that Marinol is a synthetic compound while marijuana is a hemp plant. If they both have the same active compound, maybe, we could use the marijuana legally for medical purposes. With all these debates regarding marijuana, a story in the 1994 issue of AIDS Weekly Magazine emerged. Christin Kehoe, a city councilwoman in California, said that she support the medicinal use of marijuana (Henderson, 1994, 6). Marijuana can be a drug of necessity to clients with glau coma, AIDS, cancer, multiple sclerosis, and depression. The Public Services and Safety Committee heard testimony from cancer and glaucoma patients who said that marijuana lessens side effects of chemotherapy and nausea (Henderson, 1994, 6). According to the doctors, marijuana drastically reduces the eye pressure for patients with glaucoma (Henderson, 1994, 6). The same goes with individuals suffering from AIDS, cancer and multiple sclerosis who reported

How is war understood in the Realist theoretical tradition Outline

How is war understood in the Realist theoretical tradition - Outline Example It is established in this analysis that the Realist theoretical tradition has been the most pertinent theoretical perspective on the subject of war and conflict in the post-Cold War order in the world. Realism is one of the most important positivist theories which focus on state security and power Introduction The end of Cold War brought about an inevitable focus on the concept of war and conflict in the study of international relations and several significant theoretical perspectives emerged. It is essential to realize that the realist, liberal, and radical traditions have been the most significant theoretical perspectives dealing with war and conflict in the international relations theory. Significantly, the realist theoretical tradition of war maintains that there is an enduring propensity for conflict between states in the international relations, whereas the liberal theoretical tradition identifies various ways to alleviate the conflictive tendencies and the radical theoretical tradition emphasizes on the of transformation of the entire system of state relations. As Little and Smith (2006) maintain, the realist theoretical tradition was the most dominant theoretical perspective all through the Cold War. ... ures of the American-Soviet rivalry.†1 It is pertinent to establish that state security and power above other states are the essential components of the realist theoretical tradition regarding war and conflict. Significantly, realism is not a single theory and it has several classifications which evolved considerably during the Cold War period. In an examination of how war is understood in the realist theoretical tradition, it becomes evident that the intellectual construct called ‘realism’ focuses on international anarchy, insecurity, and the state, and it provides an effective way to deal with the contemporary world politics. As it remains the overriding paradigm in the study of international relations, it is fundamental to analyze how the realist theoretical tradition explains war. Significantly, the realist theoretical tradition relies heavily on the structure of the international system or the distribution of power as the major element in explaining foreign po licies and international outcomes. â€Å"If realism provides a worthwhile explanatory framework, then propositions derived from it should yield insights about state strategies and behavior in light of this shift in the global distribution of power†¦ Realism remains a powerful and valuable explanatory framework, the end of the Cold War notwithstanding.†2 Therefore, it is important to recognize that the role of the realist theoretical tradition remains unquestioned even in the contemporary international relations and world politics, and an analysis of the realist interpretation of the concept of war is most warranted. Scope of the Study In a world threatened by the realities of war in spite of the existence of several theoretical frameworks for international relations, it is fundamental to be aware of the

Assessment in the Mental Health Setting Essay Example | Topics and Well Written Essays - 2000 words

Assessment in the Mental Health Setting - Essay Example Assessment is the first stage of the nursing process and begins with the collection of information about a patient (Hinchliff et al, 2003). In a broad sense, assessment is the foundation of nursing care and is a continuous process that nurses apply in their delivery of care (Ryrie and Norman 2010). Barker (2004) also identifies assessment as an estimation of a person’s character, and as a â€Å"decision making process based upon the collection of relevant information, using a formal set of ethical criteria, that contributes to an overall estimation of a person and his circumstances†. However it has been suggested that mental health nursing profession should integrate the broad principles of recovery approach into every aspect of nursing practice including that of assessment (DH 2006). Furthermore, a number of standardised assessment tools has been developed to support nurses further in fulfilling their professional task in clinical measurement and also in providing â₠¬Å"a general outline or the presentation of the person at a particular point in time† (Barker 2004). This essay will now identify, using evidence-based practice, a formal assessment tool used in the assessment of a patient in an acute inpatient assessment ward during a recent clinical placement. Relevant references will be cited to support statements and conclusions; appendices will also be provided to give a sample of the assessment tool used during the placement. In accordance with the Nursing & Midwifery Council’s Code of Professional Conduct (2002) guidelines, certain parts of this original essay such as the patient history will be omitted to maintain confidentiality and protect anonymity. The setting is an acute inpatient ward and a mixed gender unit. It provides a safe environment for assessment, treatment and therapeutic work helping to secure the full spectrum of mental health conditions designed to promote recovery as stated by the Department Of Health (2006). In this essay, I will pay attention to the use of the assessment instrument: Becks Depression Inventory (BDI). This inventory is basically composed of a series of queries conceptualized to measure the intensity and severity of patients with a diagnosis of mental health disorders (Polgar, 2003). The long form covers 21 questions which are meant to evaluate a specific symptom manifest among people with depression. The shorter form is composed of seven questions and is meant to be carried out by primary care givers (Polgar, 2003). This assessment tool was originally meant to evaluate and monitor depression among patients in the mental health setting and is now widely used as a measure and evaluation tool for patients with potentially depressed symptoms. I am fully aware of ethical issues on consent and so I gained a valid and informed consent of the patient in accordance with the NMC provisions (2002, section 3). The patient was made aware that this work would be confidential (NMC, 200 2, section 5). To protect her identity, she will be referred to as Helen in this paper. Helen is 65 years old and was diagnosed with bipolar disorder. She is currently in the acute mixed gender ward for assessment and treatment. For the past several years she has been admitted on and off into the ward similarly for depressed symptoms, and sometimes for manic symptoms. Rationale in selecting one type of assessment tool Using one type of assessment tool is crucial to the delivery of nursing care. The single assessment process applied to the patient helps to ensure that â€Å"older people’s needs are accurately assessed without needless duplication across different agencies†

Mesothelial-Mesenchymal Transition (MMT) Mechanism

Mesothelial-Mesenchymal Transition (MMT) Mechanism Mesothelial cells play a vital role in maintaining the structure of peritoneal membrane and peritoneal homeostasis. During long term peritoneal dialysis, prolonged exposure of peritoneum membrane to peritoneal dialysis solution causes peritoneal fibrosis. Bioincompatible dialysis fluid causes mesothelial cells to undergo uncontrolled mesothelial-to-mesenchymal transition triggered by Transforming growth factor-ÃŽÂ ²1, which leads morphological and functional disruption of membrane. This literature review is about mechanism of mesothelial -mesenchymal transition (MMT), myofibroblasts and its origin hypothesis, clock genes and their cross relation with organ fibrosis. 1.1 Peritoneum anatomy Peritoneum is defined as gliding membrane, composed of mesothelial cells maintained by basement membrane and thin layer of connective tissue. It consists of two distinct layers of mesothelium, known as parietal peritoneum and visceral peritoneum. Parietal peritoneum lines the peritoneal cavity and comes from somatic mesoderm of the embryo. Visceral covers the external surface of most abdominal organs and derived from splanchnic mesoderm of the embryo. Peritoneal cavity is potential space between both layers and is comprised of small amount of lubricating fluid, also known as serosal fluid which prevents friction between closely packed organs and allows free movement of them. [1,2] The primary function of peritoneal membrane is to provide support to abdominal organs. It also acts as passage to their blood vessels, lymph vessels and nerves. Peritoneal cavity is rich in number of cells like mesothelial cells, fibroblasts, endothelial cells, adipocytes and immune cells like macrophages, T cells, B cells, mast cells. Along with cells, they contain cytokines and growth factors, like interleukin-1 (IL-1), Transforming growth factor-ÃŽÂ ²1 (TGF-ÃŽÂ ²1), Fibroblast growth factor (FGF), and Hepatocyte growth factor (HGF). All through the development process of peritoneal fibrosis, peritoneal cells will experience changes and some of the pro inflammatory factors which act as inducers to induce fibrosis and inflammatory processes. In this designed project, we are going to focus on mesothelial cells along with Transforming growth factor-ÃŽÂ ² (TGF-ÃŽÂ ²1), which is considered as main mediator of organ fibrosis development. 1.2 Peritoneal Fibrosis caused by peritoneal dialysis Peritoneal Dialysis, an alternative to haemodialysis is being used about more than three decades ago to treat end stage renal disease. During this treatment, PD solution is introduced into the abdomen with the help of tube also known as catheter. This dialysis therapy uses peritoneum membrane as semi-permeable membrane and principle of diffusion, to diffuse waste from underlying blood vessel into the solution. PD solution is major drawback of this treatment which contributes to development of peritoneal fibrosis in patients due to its bioincompatible nature. Long-time exposure to hypertonic environment of PD solution with high glucose concentration, acidic pH, presence of Glucose Degradation Products (GDPs) and Advanced Glycation end-products(AGEs) causing functional and structural alterations in peritoneum membrane. [43] Other factor which triggers fibrosis process in peritoneum membrane during dialysis is peritonitis. Peritonitis is inflammation of peritoneum which is caused by infection that can occur either by using unsterile catheter tube, handling which lead to introduction of micro-organism into abdominal cavity. Interesting research was done by Troidle and team, where they reported that inflammation caused by Gram-positive bacteria in patient peritoneum are better managed than the one caused by gram-negative. [81] Numerous clinical studies carried out to study changes that occur in peritoneum of patients undergoes peritoneal dialysis. Till date, largest peritoneal biopsies study was carried out by William and colleague on total of 212 subjects, out of which 9 were normal individuals, 48 undergoing hemodialysis, 25 uremic and 130 subject undergoing PD. [44] There submesothelial thickness was measured, also were checked for vasculopathy and general morphological features. For normal individuals, submesothelial thickness was 50 à ¯Ã‚ Ã‚ ­m, patients undergoing hemodialysis and uremic patients was 140 à ¯Ã‚ Ã‚ ­m and 150 à ¯Ã‚ Ã‚ ­m respectively and for PD patients, thickness was 270à ¯Ã‚ Ã‚ ­m. Similar thickness of uremic and haemodialysis patients indicates that uremia can cause change in the peritoneal membrane. Value of submesothelial thickness increased to 700 à ¯Ã‚ Ã‚ ­m in long term PD patients, which directs towards fibrotic response of peritoneal to PD. They were also able to id entify vascular changes including increasing hyalinization leading to vasculopathy. These findings were confirmed by Plum et al and were able to identify link between increasing thickness of submesothelial layer and increasing transport rate of solutes. [45] 1.3 Mesothelial Cells Structural and Functional Properties Even though being mesoderm origin, mesothelial cells possess various characteristics of epithelial cells. Normally, mesothelial cells are squamous, and flattened in morphology. They are rich in cell organelles, microvilli and cilia are present on the surface. While cilia aim to regulate surfactant secretion, microvilli functions to entrap water and serous exudates in order to guard cell surface from frictional injuries. [5] Glycocalyx created by glycosaminoglycan, proteoglycans, and phospholipids surround mesothelial cells and have dual function. They form non-sticky slippery surface which supports intracoelomic movement and also provide protection against scratch. Mesothelial cells are specialized cells which plays key role in peritoneal homeostasis and maintains the integrity of the peritoneal membrane. The critical roles of mesothelial cells in peritoneum are to secrete and synthesize growth factors, cytokines and chemokines in peritoneal cavity by transport of fluid and solute across the membrane. [6] Mesothelial cells are considered as cells that are first in line in bodys defense system and they are able to sense and responds to signals within their microenvironment. They actively participate in deposition and clearance of local fibrin in the serosa membrane cavities. After mechanical injuries and infections, their fibrinolytic activity is important to prevent and remove any fibrin deposits that may forms. [7] Peritoneal membrane does act as selective permeability barrier to the channel of plasma proteins due to existence of anionic sites on mesothelial cells which in result provide net negative charge to the peritoneum membrane. In normal conditions, mesothelial cells are identified on its ability to express cell markers like occludin, claudin-1, ZO-1, Wilms Tumor-1, and E-cadherin. When mesothelial cells undergo Mesothelial-to-mesenchymal transition which we will be explained in detail later; they either unable to express them or their level expression decreases. Therefore, its important to know about all mesothelial cell markers for easy identification within pool of cells. 1.3.1 Cell markers Cell markers are defined as molecules with distinctive genetic and biochemical characteristic. These cell markers are present in cells and can be either proteins, peptides or carbohydrates and mainly present in the cells. They are used to distinguish between different cell types. Some of cell markers are specific to cell types and some are disease specific. For instance, Cancer antigen 125, calretinin and vimentin are tumor markers that are expressed by tumor cells. Some of mesothelial cells markers are positive while some are negative. Markers like hyalurnon, phospholipids, protein phosphate inhibitors-1 are formed by mesothelial cells itself. Table below shows previously studied markers for mesothelial cells and their function.

Resident fibroblast produces extracellular matrix and collagen. Myofibroblasts are the cells that are produced for carrying out the process of wound healing. In general, myofibroblast are gone through the process of apoptosis after completing healing process. It has been suggested that they become persistence after its mechanism fails and leading to more production and contraction of Extracellular matrix (ECM) and collagen causing fibrotic diseases. 2.1  Myofibroblasts in fibrosis Myofibroblasts are defined as specialized subset of cells, which are considered as the key cells in tissue fibrosis. [9] Electron microscopy showed that myofibroblast have disorganized membrane (changes that occur in actin cytoskeleton), showed presence of stress fibers, microfilament bundles and also showed adhesions in the fibroblastic cells of granulation tissue. [10] Further electron microscopy showed the presence of gap junctions which connects myofibroblasts, thus strengthening the idea of resemblance between myofibroblasts and smooth muscle cell. Myofibroblast main functions are wound healing and connective tissue remodeling. 2.2 Fibroblast differentiation into Myofibroblast To study and analyze functions of myofibroblast, a series of both in-vivo and in-vitro experiments were carried out by Hinz and Gabbiani. [15] They defined the origin of myofibroblasts as a result of 2 step differentiation of fibroblast process. [78] In initial step, fibroblasts differentiate into proto-myofibroblasts during mechanical stress and results in production of stress fibers which contains cytoplasmic actin. They also function to express and establish cellular fibronectin and are also enable to produce contractile force. Term proto-myofibroblast was given to these activated fibroblasts to differentiate them from inactive fibroblasts which are unable to produce contractile force. TGF-ÃŽÂ ²1 along with ED-A fibronectin, under mechanical stress boosts further differentiation of proto-myofibroblast into myofibroblast. They are categorized by extensive ÃŽÂ ±-smooth muscle actin level of expression and produces stronger contractile force than proto-myofibroblasts. This is a lso contributing into connective tissue remodeling. Gabbiani and Hinz also stated that unlike dermal wound healing, in pathological wound healing myofibroblasts do not vanish through apoptosis instead they lead to tissue deformation. In fact, contractures triggered by them are recognized characteristic of organ fibrosis. [79] 2.3 Hypothesis surrounding Myofibroblasts origin The origin of Myofibroblasts in fibrotic tissue has been much debated, with disparate findings likely to stem from the range of different fibrotic diseases investigated and the array of technical approaches taken. [11] Most of the proposed theories have different cellular sources and mechanisms which lead to their origin (Figure 3). Previous studies on dermal fibrosis proposed that mesenchymal-like cells known as pericytes are resident source of myofibroblasts. Immunohistochemistry and double immunofluorescence of patients biopsies showed phenotype link between pericytes and myofibroblasts. [80] It has been described that pericytes can differentiate into osteoblast, adipocytes, and smooth muscle cells. Research carried out by Lin et al., on Col1a1-GFP mice and Humphreys et al., using FoxD1-Cre knock-in mice, both transgenic mice with aim to identify pericytes in genetically labelled renal stroma to suggest that major source of myofibroblasts is pericytes, a contractile cell. [12, 13] A limitation of the aforementioned studies is the lack of lineage tracing strategies and the use of non-specific markers to identify pericytes. Markers such as CD73, PDGFR- ÃŽÂ ² (Platelet-derived growth factor receptor- ÃŽÂ ²) and neural/glial antigen 2 (NG2) used in these studies are also expressed by resident fibroblasts. Endothelial to mesenchymal transition (EndoMT), similar process to EMT can be another potential source myofibroblasts. Study done by Zeisberg on three independent mouse models with chronic kidney diseases to study renal fibrosis found that EndoMT may contribute in fibrosis as about 30-50% myofibroblasts were able to express ÃŽÂ ±-SMA and fibroblast-specific protein-1(FSP-1) and also endothelial cell markers CD31. [16] This indicates myofibroblasts may originate from endothelial cells. Myofibroblasts may also be derived from bone marrow. An elaborate series of studies carried out by Direkze et al., used molecular staining techniques for the detection of Y chromosome markers in irradiated female mice which were transplanted with male bone marrow. [18] They used skin wounding and paracetamol administration to create selection pressure to encourage engraftment of bone marrow derived myofibroblasts. They were able to identify myofibroblasts in the gut through their ability to express o f alpha- smooth muscle actin and their morphologies. These findings are controversial however, as other groups have failed to identify BM derived myofibroblasts. A recent study carried out by Yi Ting Chen et al., did genetic fate mapping of Wilms Tumor-1 positive cells on peritoneal fibrosis models. Fibrosis was induced either by dialysis solution, overexpression of TGF-ÃŽÂ ²1, or sodium hypochlorite. [19] Results of this study postures as a challenge to the significance of mesothelial cells as probable source of myofibroblasts. It showed rather than mesothelial cells, underlying submesothelial resident fibroblast give rise to collagen producing myofibroblast. Results of genetic fate mapping of WT1+ mesothelial cells showed that after peritoneal injury, remaining mesothelial cells repair the disrupted peritoneal membrane by contributing to remesothelialization, but do not undergo MMT. While previous studies used Wt-1 as a biomarker and Cre recombinase to trace the fate of mesothelial cells. This makes it obvious that Chen finding still needs to be confirmed. This study also The last proposed theory for origin of myofibroblast is epithelial -mesenchymal transition. Epithelial-Mesenchymal transition (EMT) is commonly defined as process during which transition to mesenchymal cells, epithelial cells lose their cell-cell adhesion and their polarity. Followed by obtaining mesenchymal markers like FSP 1, HSP47, ÃŽÂ ±-SMA and vimentin but loses epithelial markers. [20] Myofibroblasts derived from epithelial cells through EMT proposed theory got strong piece of evidence from immunohistochemical study of peritoneal fibroblasts of continuous ambulatory peritoneal dialysis (CAPD) patients carried out by J-Heffernan et al. [14] Biopsies samples were taken from CAPD patients and divided into four groups: normal (I), non CAPD uremic (II), CAPD uremic (III) and non- renal patients with inguinal hernia (IV). Markers like desmin, E-cadherin, cytokeratins, ÃŽÂ ±-SMA and also CD34 were analysed for expression by mesothelial cells and resident fibroblasts. Group I and II did expressed CD34 but no other markers. The reverse pattern was observed in other two g roups. Degree of peritoneal fibrosis is connected with loss of CD34 expression. Myofibroblasts appear to originate from both by activations of resident fibroblasts and by mesothelial-to-mesenchymal transition of mesothelial cells. 3.0 Mesothelial-Mesenchymal Transition (MMT) Under regular conditions, Mesothelial-to-mesenchymal transition of mesothelial cells is an autoregulated biological process which functions to repair tissues but under uncontrolled situations (Long term Peritoneal dialysis) they can cause Peritoneal fibrosis. 3.1 Stages of MMT Mesothelial -Mesenchymal Transition (MMT) is similar process to Epithelial Mesenchymal Transition (EMT). Defined as a step-wise and complex process where mesothelial cells undergo modifications in their architecture and molecular functions. [21] [48] Simple steps in which process of MMT occurs starts with the downregulation of intracellular adhesion molecules causing loss of microvilli, apical-basal polarity and disrupting intracellular tight junction. These transition undergoing cells adopt front to back polarity, have increased in their migration capacity, morphological changes and are able to express ÃŽÂ ±-SMA. The main objective of this process is to repair wounded tissues and also play role in process like migration of cells, inducing neoangiogenesis and production of extracellular matrix. Molecules and signaling pathways that play role of either inducers or blocker during the process of MMT are TGF-ÃŽÂ ²1 induced signaling pathways and BMP-7 signaling pathway. They are member of superfamily of growth factors, along with activins/inhibin and growth and differentiation factors (GDFs). Main attention is on growth factors because equilibrium between these factors maintains the epithelial like-phenotypic characteristics of Mesothelial cells and also in acquiring mesenchymal cells characteristics. Studies not only showed that high levels of cyclooxygenase (COX)-2, CTGF and VEGF are expressed by mesothelial cells that undergo MMT. But also that there is connection between expression of these molecules and rate of transport of solute across peritoneal membrane. These molecules are also caught up into fibrotic, angiogenic and also in inflammatory responses. [49][50][51] 3.2 Cell Signaling Pathways Activation of TGF- ÃŽÂ ², master molecule in peritoneal fibrosis during Peritoneal Dialysis, starts MMT signalling cascade with activating receptors that triggers smads- dependent (GSK-3, ÃŽÂ ²-catenin, Lef-1/Tcf, integrin-linked kinase) and smads-independent signalling (H-Ras/Raf/ERK) pathway. [48][52][53][54] Smad are intracellular proteins that functions to transfer signals from TGF-ÃŽÂ ² to nucleus for gene transcription. Smad dependent signalling pathways activates when TGF-ÃŽÂ ² and BMP-7 binds with their respective receptor type II (TGF R-II and BMP R-II respectively). The binding leads to activation of receptors type I of TGF and BMP-7. These receptors type I functions to carry out phosphorylation process. TGF R-I phosphorylates Smad2 and Smad3 in TGF-ÃŽÂ ² pathway and Smad1, Smad5 and Smad8 by BMP R-I. These activated Smads forms heterodimers with Smad4. Followed by translocation of these complexes into the nucleus where they function to activate genes involved in either process of MMT and rMMT (Fig. 5) Presence of few other BMP-7 modulators may affect the signalling of BMP-7. Smad dependent signalling pathway of TGF-ÃŽÂ ² and BMP-7 are controlled by Smad7 and Smad6 respectively. In case of Smad independent pathway of TGF-ÃŽÂ ² and BMP-7 involves a protein kinase TAK1, which functions to regulate processes like transcription and apoptosis. In TGF-ÃŽÂ ² signalling pathway, TRAF6 initiates activation of TAK1 which further leads to activation of p38 and MAPK-JNK signalling pathway. Receptor type I of TGF-ÃŽÂ ² phosphorylates Shc, which helps in activating MAP kinase ERK1/2 signalling pathway. p38 pathway act as blocker of mesothelial cells conversion to mesenchymal. Maybe its due to the fact that XIAB, a protein belonging to the family of inhibitor of apoptosis protein helps BMP-7 to activate p38 signalling pathway. TGF-ÃŽÂ ² also encourages PI3-K/Akt pathway by inactivating GSK-3ÃŽÂ ², to stabilize ÃŽÂ ²-catenin and snail and to activate mTOR. This results in localisation of ÃŽÂ ²-catenin into the nucleus, where they interact with LEF1/TCF, in order to feed into Wnt signalling pathway. They also contribute in the transcription of mesenchyma l-related genes. Furthermore, localisation of snail into the nuclear encourages transcriptional repression of E-cadherin and several other adhesion molecules. Smad dependent or independent pathway, both depicts the fact that TGF-ÃŽÂ ² plays a key role in developing fibrosis by promoting mesothelial to mesenchymal transition. Another fact is BMP-7 plays role of antagonist to TGF-ÃŽÂ ². Utmost studies has used TGF-ÃŽÂ ²1 as their target goal to design therapeutic treatment for peritoneal fibrosis. Most of them intend to control TGF-ÃŽÂ ²1 activity either via drug or synthetic proteins design specifically for this purpose. 3.3 Evidences of Mesothelial-mesenchymal transition (MMT) There are more than enough studies results which clearly supports the process of MMT occurring fibrosis but in 2003, Yanez-Mo et al., published breakthrough in-vitro and in-vivo study where they were able to demonstrated MCs undergoes mesenchymal conversion. [46]. Primarily in vitro studies were carried on by isolating mesothelial cells from patients undergoing peritoneal dialysis. These isolated cells were characterized using immunostaining, western blotting, flow cytometry and reverse-transcriptase polymerase chain reaction. Mesothelial cells from omentum from healthy persons were used as control and all results were compared. Morphological analysis sample showed varies morphologies ranging from cobblestone like appearing cells to fibroblast like cells. Mixed morphology and non-epithelioid were also observed in few samples. Level of E-cadherin, cytokeratin and vimentin were analyzed for the mesothelial-to-mesenchymal transition in mesothelial cell cultures. Results demonstrated not iceably low level of E-cadherin and cytokeratin expression in both cobblestones like cells and non-epithelioid cell as compared to omentum cell cultures. In non-epithelioid cells, vimentin has high expression level. Expression of snail and E-cadherin in mesothelial cells isolated from effluent and omentum were analyzed by the process of RT-PCR. While in omentum mesothelial cells, showed no presence of snail mRNA but increase in expression of these messenger RNA in effluent derived mesothelial cells. These results were established after carrying out in vivo studies of peritoneal biopsy samples. With dual aim of studying anatomical changes in peritoneal membrane and correlating them with functional parameter, Del Peso and team carried out a clinical study. [47] They used peritoneum biopsies taken from thirty-five steady patients which were still taking peritoneum dialysis treatment form last 2 years. They observe loss of mesothelial layer in about 74% patients, fibrosis in 46%, 17% showed presence vasculopathy. With submesothelial cytokeratin staining, 17% showed evidence of EMT. Interestingly, they found that myofibroblasts were present in all patients with EMT but only in 36% without EMT. 3.4 Potential therapeutic approaches to reverse MMT (rMMT) Several studies describe therapeutic strategies which are targeting anti-EMT of Mesothelial cells are emerging as promising treatment against fibrosis development. Tamoxifen is a drug used for treating breast cancer. The tamoxifen is oestrogen receptor and their activity affects action of TGF- ÃŽÂ ²1 has been reported. In year 1991, Clark and team showed noticeable decrease in level of peritoneal fibrosis, when given orally to peritoneal fibrosis patients. Loureiro and team also used this drug to study its effect in early stage of PD induced peritoneal fibrosis. [61] Theyused PD model of mice for in-vivo study and along with that they also did in-vitro study. In vitro studies were carried out with mesothelial cells (MCs) derived from omentum and effluent. Mesothelial cell sample cultures were checked for any change in morphology and also level of E-cadherin expression after treating them with Tamoxifen. For effluent derived MCs, MMT was not reversed by Tamoxifen but some mesenchymal molecules expression was reduced. In mice PD model, they confirmed that MMT and thickness of peritoneal membrane increases parallel. They also observed that Tamoxifen does reduce thickness of peritoneal membrane and improves its function. They also administrated P17 and P144, synthetic peptides that were designed to bind with TGF-ÃŽÂ ²1 directly. [62] It has been reported that in organs like liver, heart, skin these peptides have shown strong antifibrotic effect by blocking biological function of TGF-ÃŽÂ ²1. Bone morphogenic protein-7 (BMP-7) and Hepatocyte growth factor (HGF), are two molecules that were successfully demonstrated their ability to inhibit and reverse process of Mesothelial to mesenchymal transition and renal fibrosis in animal models by X Y D et al., and Yang et al. [64] [65] In vitro study carried by Yang and team, where they used histone acetyltransferase inhibitor (HAT) C646 in EMT model of HPMCs. [66] EMT was induced by treating with high glucose. C646 treatment of EMT model, found TGF-ÃŽÂ ²1/Smad3 signalling was blocked. This might provide with a novel therapeutic treatment for peritoneal fibrosis. Even though most of the therapeutic studies focused on mesothelial mesenchymal transition process and TGF-ÃŽÂ ²1, there are other factors that contributes to loss of functional properties of peritoneum.

Public Prayers at High School Sporting Events Essays -- essays researc

Public Prayers at High School Sporting Events The Supreme Court has just received Santa Fe v the people, in this case the students was banned from saying a prayer at a foot ball game . The constitution protects the right to free speech. Therefore, there is no reason for this case to have come up in the first place. If someone does not want to hear a prayer, they do not have to listen to it. If I were the judge I would rule that banning prayer at school events is unconstitutional. The first reason I would use that banning prayer is unconstitutional is the first amendment to the constitution says, â€Å" Congress shall make no laws against free expression of religion†. The right to free expression of religion is one of the fundamental freedoms this country was founded on. Therefore, if Cong...

Coach Johnson Essay

1.Some Various forms of power include coercive, compliance gaining, expert, and reward power (Interpersonal Communication: Relating to others pg. 229-230). The kind of power that Coach Johnson has on his team very to comply with coach Johnson’s goals like going to the championships. 2.The turning point was when Gilbert decided to go talk to Coach Johnson because from there and on Coach Johnson yelled at gilbert had a bad conversation. Yes I think it was the same turning point for Coach Johnson because he felt more frustrated because he does not like people telling how to run things. If one has a positive turning point and the other has a negative, the person with the positive turning point might be calmer and actually talk things out. 3.The turmoil stage, the conflict was increase and unclear relationship happened when Gilbert approach the Coach. The stagnation stage, communication declined and both took each other for granted because they were mad at each other, Gilbert because he wanted more playing time and Coach Johnson because he doesn’t like people telling him how to run things. The de-intensification stage, decreased interaction and distance both were to mad at each other that they didn’t want to talk. The individualization stage, when both are more individual than being more of a team. The separation stage, when they try to eliminate further communication between them, this is when Coach Johnson decides to put James over Gilbert. The final stage is post-interaction stage, this happened when gilbert wants to quit the team and go his separate way. (Interpersonal Communication: Relating to others pg. 263-265) 4.Social exchange theory is an economic model of human behavior used to explain how people arrive at decisions, posits that people seek the greatest amount of reward with the least amount of cost (Interpersonal Communication: Relating to others pg.267). Well the cost would be the relationship and the rewards would be the rewards you are gaining from the relationship. Coach Johnson decided to put James in instead of Gilbert because he was not gaining any rewards from Gilbert because Gilbert was not playing good. 5.Attitude can be communicated verbally when Gilbert talked back to his coach. Attitude can also be communicated verbally when Gilbert talked back to his coach. Attitude can also be communicated non-verbally, this happened when his teammates seen Gilbert always mad through his face expression. Attitude affects long term relationships because when people have an attitude they tend to say things they don’t  mean. Gilbert might want to recognize his mistakes in the games and work harder and talk to Coach Johnson when he is calmer and relaxed, Gilbert should also apologizing to his team for not being his best on team.

7 freedom fighter Essay

Netaji as he was called was a very prominent figure in the Indian freedom struggle. His sole aim was the freedom of his country and he termed it as a necessity and didn’t agree with Gandhiji on the terms that it can be negotiated. He was well educated and believed that there should be complete intolerance for caste-differentiation, racism or religious separation. His was so active in the Indian National Congress that he was arrested several times by the British Government. Soon he realised that international backing was a must for India’s freedom and hence started meeting leaders from Japan, Italy, and Germany who were against the British forces in the World War 2. He even met Mussolini and Hitler at different times. He was completely against the racism that The dictators propagated but he appreciated the discipline and unity of their men. It was on Hitler’s Suggestion that he went to Japan and formed the Indian National Army and started the Campaign ‘Chall o Dilli’ which though failed, wasn’t enough to break his spirit. The Slogan ‘Jai Hind’ was also given by him which still prevails. Bhagat Singh See more: Satirical essay about drugs A revolutionary who was brought up in the patriotic atmosphere, Shaheed Bhagat Singh, where Shaheed means ‘Martyr’, from a very young age all he ever dreamed was of seeing his country free. He met Rajguru and Sukhdev who shared his thoughts and together they fought several guerrilla wars fighting and revolting every British law that was against the civilians and also against the right of humanity. The Jallianwalla Baugh Massacre is one such example of the colonial inhumanity. He even blasted bombs inside the Assembly hall shouting slogans of ‘Inqualab Zindabad’( Independence Prevails) to revolt against two laws-â€Å"Trade Union Dispute Bill† and â€Å"Public Safety Bill†. All three were arrested and hanged to death. Their death, instead of silencing the people, actually acted as catalyst that ignited the fire within people as even while leaving all three kept uttering-â€Å" Sar Kata Sakte Hai mar, Sar Zhuka Sakte Nahi† ( We can have ou r heads chopped but not bowed). Chandrasekhar Azad Chandra Shekhar Azad pronunciation (help ·info) (23 July 1906 – 27 February 1931), popularly known as Azad (â€Å"The Liberated†), was an Indian revolutionary who reorganised the Hindustan Republican Association under the new name of Hindustan Socialist Republican Association (HSRA) after the death of its founder, Ram Prasad Bismil, and three other prominent party leaders, Roshan Singh, Rajendra Nath Lahiri and Ashfaqulla Khan. He is considered to be the mentor of Bhagat Singh and chief strategist of the HSRA.Ram prasad Bismil Ram Prasad Bismil Ram Prasad Bismil About this sound pronunciation (help ·info) (11 June 1897 – 19 December 1927) was an Indian revolutionary who participated in Mainpuri conspiracy of 1918, and the Kakori conspiracy of 1925, and struggled against British imperialism. As well as being a freedom fighter, he was also a patriotic poet and wrote in Hindi and Urdu using the pen names Ram, Agyat and Bismil. But, he became popular with the last name â€Å"Bismil† only. He was associated with Arya Samaj where he got inspiration from Satyarth Prakash, a book written by Swami Dayanand Saraswati. He also had a confidential connection with Lala Har Dayal through his guru Swami Somdev, a preacher of Arya Samaj. Bismil was one of the founder members of the revolutionary organisation Hindustan Republican Association. Bhagat Singh praised him[1][2] as a great poet-writer of Urdu and Hindi, who had also translated the books Catherine from English and Bolshevikon Ki Kartoot from Bengali. Several inspiring patriotic verses are attributed to him; these include the poem Sarfaroshi ki Tamanna, although that is sometimes also said to be the work of â€Å"Bismil† Azimabadi of Patna.Surya Sen Surya Sen (Bengali: à ¦ ¸Ã  §â€šÃ  ¦ °Ã  § Ã  ¦ ¯ à ¦ ¸Ã  §â€¡Ã  ¦ ¨) (22 March 1894 – 12 January 1934) was a Bengali independence fighter (against British rule) who is noted for leading the 1930 Chittagong armoury raid In Chittagong of Bengal in British India (now in Bangladesh). Sen was a school teacher by profession and was popularly called as Master Da (â€Å"da† is a suffix in Bengali language denoting elder brother). He was influenced by the nationalist ideals in 1916, when he was a student of B.A. in Behrampore College.[1] In 1918 he was selected as president of Indian National Congress, Chittagong branch. Madan Lal Dhingra Madan Lal Dhingra (1883–1909) was an Indian revolutionary freedom fighter.[1] While studying in England, he assassinated Sir William Hutt Curzon Wyllie,[2] a British official, hailed Early life  Dhingra Studied at Amritsar in MB Intermediate college up-till 1900 and then went to Lahore to study in Government College Lahore. In 1904 he led a student protest against the principal’s order to have college blazer made out of imported cloth from England. He was thrown out of college. At that time he was Student of Masters of Art. He was under the influence of Nationalist Movement of Swadeshi. He deeply studied the literature concerning the cause of Indian Poverty and famines, as solution to these problems Swaraj and Swadeshi became key issues. Then Dhingra had to work as a clerk, at Kalka in A Tonga Service being run for British family’s transport to Shimla Tonga (horse-driven cart) puller, and a factory labourer. Dhingra attempted to organise a union there, but was sacked. He worked for sometime in Mumbai, before acting upon the advice of his elder brother Dr Bihari Lal and going to England for higher studies. In 1906, Madan Lal departed for England to enroll at University College, London, to study Mechanical Engineering. He was supported by his elder brother and some nationalist activists in England. Udham Singh Udham Singh (26 December 1899 – 31 July 1940) was an Indian revolutionary, best known for assassinating Michael O’Dwyer on 13 March 1940 in what has been described as an avenging of the Jallianwalla Bagh Massacre.[1] Singh is a prominent figure of the Indian independence struggle. He is sometimes referred to as Shaheed-i-Azam Sardar Udham Singh (the expression â€Å"Shaheed-i-Azam,† Urdu: Ø ´Ã™â€¡Ã›Å'Ø ¯ Ø §Ã˜ ¹Ã˜ ¸Ã™â€¦Ã¢â‚¬Å½, means â€Å"the great martyr†). Early life Singh was born Sher Singh on 26 December 1899, at Sunam in the Sangrur district of Punjab, India, to a Kamboj Sikh farming family. His father, Sardar Tehal Singh Jammu (known as Chuhar Singh before taking the Amrit), was a railway crossing watchman in the village of Upalli. His mother died in 1901, and his father in 1907.[2] After his father’s death, Singh and his elder brother, Mukta Singh, were taken in by the Central Khalsa Orphanage Putlighar in Amritsar. At the orphanage, Singh was administered the Sikh initiatory rites and received the name of Udham Singh. He passed his matriculation examination in 1918 and left the orphanage in 1919.

Berlin Brandenburg Airport Project To Report To The Project Board And Critical Reflections On The Role Of Being A Project Manager Executive Summary Berlin Brandenburg Airport Project To Report To The Project Board And Critical Reflections On The Role Of Being A Project Manager )..   This will help to ensure that the project is implemented in light of the lessons which have been learnt far.   The most important lessons which have been learned so far should be considered at the next Project Board meeting.   These have been identified by reviewing the project’s progress to date (BBC, 2013; Local, 2013).   Therefore the lessons that need to be considered are: The importance of maintaining ongoing communication with all stakeholders (Wang and Huang, 2006). The importance of contingency planning (Anderson and Grude, 2009). The importance of feasibility studies and the appraisal of various management systems e.g. for fire safety or for baggage transportation (Kerzner, 2012) (based on BBC, 2013; Local, 2013). At the next Project Board meeting each of these three factors should be considered, as each one has had a detrimental effect on the project to date (BBC, 2013; Local, 2013). The Board should consider how ongoing communication is managed with stakeholders, as to date the project failures have been widely published (BBC, 2013; Local, 2013).   This has led to concerns being raised over the project’s implementation and the capabilities of the project team (BBC, 2013; Local, 2013).   Its well documented that stakeholder engagement is a key factor which may affect a project’s success or failure (see as an example; Phillips et.al. 2012; Wang and Huang, 2006; Yuan et.al. 2009).   Therefore, it is imperative that the Board considers the ongoing stakeholder engagement and seek to learn from our recent experiences. Additionally, another important factor that the Board should consider is the implementation of contingency planning for the remainder of the project.   To date, a number of technical issues have arisen, however due to the lack of contingency planning in the early stages of the project the costs have now risen and the delivery timeline has increased (BBC, 2013; Local, 2013).   If contingency planning was utilised in the early stages of this project it is more likely that it could have been delivered (Thamhain, 1986) in line with the programme and on budget with the required quality standards (Anderson and Grude, 2009). Furthermore, another important lesson that the Board should consider is the importance of undertaking feasibility studies (Soderlund, 2002) and the appraisal of various management systems e.g. for fire safety or for baggage transportation.   To date, the delays in this project have stemmed from critical systems failures (Kerzner, 2012).   The importance of undertaking meaningful feasibility studies to achieve project success is well documented (see as an example: Mackenzie and Cusworth, 2007; McNulty, 2004).   Therefore, to ensure that these problems do not arise again, it is imperative that the Project Board seeks to review and plan how feasibility studies will be conducted for the remaining duration of this project. Each of these factors and the impacts that they have had on the project’s implementation to date (BBC, 2013; Local, 2013) must be considered by the Project Board at their next meeting (Anderson and Grude, 2009).   If these issues are considered, discussed and plans are implemented to seek to redress these (in line with the recommendations that have been outlined for each one above) it is possible that the project will be delivered within the revised programme, to budget whilst meeting the quality standards that are necessary (Mackenzie and Cusworth, 2007; McNulty, 2004).   This is imperative to seek to ensure that no more delays are caused by the project team and to ensure that the costs and project programme do not need to be increased further (Thamhain, 1986), as this will have a detrimental impact on how our stakeholders view the project. 4. Critical Reflections of the Role of a Project Manager Project managers need to have a variety of skills in order to successfully implement projects in a variety of settings.   The key skills that are pertinent to them being able to attain success are as follows: Be organised (Frame, 1999) Be able to multi-task (Kerzner, 2013) Being able to prioritise (Atkinson, 1999) Be able to disseminate information clearly (El-Sabaa, 2001) Be a leader of people (Pinto and Trailer, 1998) Be able to foresee issues and seek to mitigate them (Kerzner, 2003) Be able to understand costs and predict when these may increase. Be able to plan a project and manage its programme (Brown, 2000) Be able to engage stakeholders positively (Verma, 1996) Understand and communicate priorities so that the project team delivers on time (El-Sabaa, 2001). Be aware of quality standards and ensured that they are adhered to throughout the project (Atkinson, 1999) Each of these factors affects the successful implementation of projects (Kerzner, 2013).   To date, many of these skills have been learnt from practically implementing projects, as project manager’s gain experience through undertaking these their skills improve (El-Sabaa, 2001).   Through my experience, I have already gained many of these skills.   However, it is necessary for me to improve my communication and engagement skills as most of the work that I have undertaken has been away from relevant stakeholders or insider my project team.   Therefore, it would be useful to engage with some external stakeholders so that I could enhance my communication and engagement skills in practice (Brown, 2000). 5.Conclusion In conclusion, this report was compiled to seek to inform the project board of how our stakeholders may be perceiving delays which have arisen during the Brandenburg Airport project (BBC, 2013).   A number of solutions have been provided for the Project Board to consider.   It is hoped that the implementation of these will enable the project to be completed to quality standards, on time and to budget. 6.

Privacy and Internet Policy Research Paper Example | Topics and Well Written Essays - 1750 words

Privacy and Internet Policy - Research Paper Example Everybody person has the right to privacy of personal information which is private in nature. George Reynolds, in his book â€Å"Ethics in Information Technology,† argues that â€Å"Privacy is the right to be left alone – the most comprehensive of rights, and the right most valued by a free people† (Reynolds, 2010). People prefer to keep their private information secret because they do not want it to be misused by others. So they safeguard it with the help of laws as also with the help of software etc. The concept of consumer profiling is also relevant in this context. It deals with sketching of important psycho-graphical and demographical information concerning the user of a product. Such data consists of details like gender, age group, education, place of living, profession, income scale, marital status etc. Some companies explicitly gather personal information about the users of internet when they register at their websites by way of making them fill certain forms. The threat in this case is that personal data is collected and certain companies sell this information to other firms without the consent of consumers. Thus, the internet exposes individuals to the threat of leaking their private information. Therefore, protecting consumer data is a significant concern while using the internet for various purposes. Though all companies have a privacy statement, explicitly given on their websites, one cannot rule out the possibility that â€Å"existing privacy enhancing technologies fail in the event of a vendor operating against their stated privacy policy†. , leading to loss of customer privacy and security† (Pearce & Bertok, 1999, para. 1). Personal information transacted through online can be misused, which will lead to failure in safeguarding customer privacy. There are some laws to prevent the misuse of personal data, but these are not sufficient to fully safeguard privacy. Therefore, there is an urgent need to enhance or supplement the existing regulations to completely

Bacterial Meningitis Research Paper Example | Topics and Well Written Essays - 1250 words

Bacterial Meningitis - Research Paper Example d deep kissing, suffer from chronic ear and nose infection, and who have contracted pneumococcal pneumonia are at a higher risk of developing this disease. This ailment is characterized by high fever, headaches, increasing drowsiness, and irritability. Immediate medical attention has to be obtained, upon suspecting the presence of this disease. In general, it is advisable to undergo hospitalization. The recommended therapy is to administer antibiotics. Despite the reported 10% fatality rate of this disease, early diagnosis and treatment have ensured recovery in the majority of the patients. The most common cause of meningitis is bacterial or viral infection that has commenced in some other region of the body. Some examples are, the ears, sinuses, or upper respiratory tract. On occasion, meningitis results from autoimmune disorders, fungal infections, and medications. Bacterial meningitis proves to be contagious with regard to people who are in close physical contact (Johnson, 2013). The inflammation of the meninges or the membranes that enclose the spinal cord and the brain, constitutes bacterial meningitis. The cause of the inflammation is bacterial infection that can prove to be fatal. These bacteria are present in the mouth, nose, throat, and spread from an infected individual to another via coughing, osculation, or the sharing of food or beverages. This infection can also spread from an infection of the brain, ear, nose, sinus, or throat. Such infection can also be spread by a head injury or head surgery (Drugs.com, 2013). Among children and young adults, meningococcus or Neisseria meningitides, and Streptococcus pneumonia occur frequently. These are the principal causes of meningitis in the US, and there are vaccines available for Neisseria meningitides, and Streptococcus pneumonia. These vaccines have been recommended for all the people who are special risk. The bacteria tend to spread from individual to individual via coughing and sneezing (Johnson,
