ABSTRACTThe stochastic behavior of both transfusion (demand) and blood donations (collection) is a challenge for the blood supply chain. Although donations are not fully within the control of blood supply chain, the blood service can marginally moderate it by postponing appointments in the case of having an overstock, or by triggering a call for additional blood when faced with shortages. Such shortages are often observed as a consequence of catastrophic events. Past studies show that the response to a call for blood after a disaster is substantive. Yet the consequential impact on the supply chain is not well understood. This is due to the perishability of blood and the fact that donors are not eligible to give blood for a certain period after a donation has been made. In this study, the donation process is modeled with a Markov chain and the impact of a call for blood resulting from a disaster is investigated. This article highlights new actionable insights that aid planners to mitigate the negative impacts of a substantial response to a call for blood.

What is blood? The many meanings of blood vividly attest to its polyvalent qualities and its unusual capacity for accruing layers of symbolic resonance. Life and death; nurturance and violence; connection and exclusion; kinship and sacrifice – the associations multiply, flowing between domains in a quite uncontainable manner. Whether expressed in the rhetoric of familial, racial, ethnic, or national exclusion, or in calls to violent action, idioms of blood often have exceptional emotional force. Drawing together the historical and ethnographic case studies presented in this volume – from the literal presence of blood in spaces of blood donation to the metaphorical deployment of sanguinary idioms in depictions of the economy – this introduction examines blood's special qualities as bodily substance, material, and metaphor. In sketching out a 'theory of blood', it suggests why such a comparative undertaking might be of value.

This article uses the conceptual space of "brown blood" to analyze United States v. Bhagat Singh Thind at the intersection of race and caste. The racial politics of blood has been somewhat submerged in the ongoing discussions of racism and racialization, which have been dominated by the representational politics of skin color. However, the Thind case, as I argue, hinges on an understanding of racial blood politics that intersected with casteist discourses that were also emerging globally. On the one hand, brown blood represents the romantic ideas associating brownness with assimilation. This dimension of brown blood allowed for the ascendance and mobility of savarna Indians in the late twentieth century. At the same time, the Thind case hinged upon the racialization of caste in India's late-nineteenth-century colonial-caste society. I show how caste-as-blood set in motion new migratory patterns and mobility regimes for perceived dominant caste peoples, which, ultimately, initiated further accumulationist possibilities. My analysis serves to illustrate the complex interactions of race and caste in current global geopolitics, an understanding that is especially important as more and more dominant caste Hindus have intimate relations with and power within the United States.

The 17th Century Parisian doctor who made blood transfusion history...In 1667 a Parisian doctor by the name of Jean-Baptiste Denis performed an operation that had never previously been attempted - he transfused blood into another human being. This was the first attempt at a procedure that over subsequent centuries was to save the lives of thousands of people. But at the time Denis was nearly convicted of murder.The victim of Denis's experiment was a middle-aged man suffering from mad rages. Denis believed that by transfusing the blood of a calf into the man the man would assume the placid natu

Blood doping, or the infusion of autologous blood into trained athletes, has been theorized to increase endurance capacity. However, a review of 16 studies which have investigated various aspects relative to the effect of blood doping on endurance capacity and related physiological and psychological parameters, such as exercise HR, VO2max, and ratings of perceived exertion, has revealed inconsistent results. Due to the fact that most research designs employed to date have experienced some methodological irregularities, the efficiency of blood doping as an ergogenic aid for athletes has not been established.

Acute organ damage and the ensuing multiple organ failure are the result of a pathophysiological process involving various cytokines. Once activated, these proteins cannot be eliminated even when the kidneys function at their maximum capacity. To counteract this mechanism, researchers in Japan have developed an innovative concept employing blood purification to remove the overwhelming cytokines.This book describes the use of hemodiafiltration to inhibit the cytokine storms which cause serious organ damage in patients with septic shock. Moreover, the technical construction of the blood purification system, which includes various machines, devices, membranes, fluids, etc., is explained in detail. Finally, leading experts discuss the concept of continuous renal replacement therapy as the standard care in critically ill patients with severe acute kidney injury.Describing the current state of acute blood purification, this publication provides new impulses and opens new avenues in the treatment of acute organ damage

In ancient times there was blood a symbol of life flow and energy. It was believed that it gives strength. Red paint and wine were used in traditional rites.Blood type is able to tell a lot of interesting things about its "owner" facts. Having information about your own blood type can be better to understand yourself and your body. The purpose of the article. In Article studies on the history of medicine, which form new ones, are considered ideas about the formation of blood groups. The novelty of the study due to the fact that the idea of ​​blood groups from year to year replenished with new data, which encourages the historical sketch. Main part. With increasing population and changing the environment reduces the possibility to get meat food. As a result, this led to the emergence "Vegetarian" second blood group A. Resettlement of peoples in Europe is the reason for the predominance of people with the second blood group there at this time. It is believed that the homeland of the gene of the third group B is located in the foothills of the Himalayas, in present-day India and Pakistan. The fourth blood group AB arose as a result of mixing holders of gene A and carriers of gene B. Today only 6% Europeans have a fourth blood type, which is the youngest in ABO system. The uniqueness of this group in the inheritance of high immunological protection, which is manifested in resistance to autoimmune and allergic diseases. Conclusions. Evolution human is impossible without a systematic change in gene frequencies population. Is evolution continuing now? Thoughts sometimes contradictory. Some believe that man has reached the top evolutionary tree, others disagree with such conclusions.

By KIM BELLARD People are fascinated by blood. Well, it would seem so, given our fondness for vampires, gory movies, and true crime stories. I'm not so keen on any of those,Continue reading...

This essay gauges the significance and legacy of Carolyn Cooper's Noises in the Blood: Orality, Gender, and the "Vulgar" Body of Jamaican Popular Culture (1993). It discusses the book's impact across and against the "Black Atlantic" paradigm, the rise and limits of global feminisms, and shifts in Black popular and academic cultures in the 1990s. Just past its thirtieth anniversary, the book's critical methodologies enabled much of contemporary thinking about race, gender, and popular cultures in the African diaspora. However, it also establishes some aesthetic and political refusals that are still necessary in an intellectual climate where the Caribbean continues to struggle against the hegemonizing demands of elite Pan-African solidarities.

In The Gift Relationship (London: Allen & Unwin, 1970) Richard Titmuss argued that the UK system of voluntary blood donation was economically, medically, & morally superior to the US system, in which many blood suppliers are paid. The argument was badly put & fiercely attacked, but substantially correct. Developments since Titmuss wrote, especially the acquired immune deficiency syndrome (AIDS) epidemic, have tragically reinforced his main point: 50+% of severe hemophiliacs in the UK have been infected with the AIDS virus through imported, paid-for blood products. Titmuss's normative argument is reconstructed, & defended against neoclassical economists who have been his fiercest critics. Policy implications are briefly discussed. 2 Tables, 33 References. HA
