A survey of xenograft rejection mechanisms

Det finns idag fyra mekanismer beskrivna för avstötning av xenotransplantat. Dessa är hyperakut avstötning, akut humoral xenotransplantat avstötning, akut cellulär xenotransplantat avstötning och kronisk avstötning. Hyperakut avstötning medieras av naturliga xenoreaktiva antikroppar, vilka främst är riktade mot antigenet ?-Gal på svinceller och aktiverar komplement systemet (den klassiska vägen). Akut humoral xenotransplantat avstötning medieras också av xenoreaktiva IgM och IgG, som verkar skada xenotransplantatet bland annat genom aktivering av komplementsystemet och endotelceller.

Magnesium chloride in dry cow silage to prevent hypocalcaemia

Milk fever, or parturient paresis, is the second most common disease in Swedish dairy cows. The disorder is associated with the onset of lactation when some cows are unable to meet the metabolic demands of calcium to support milk production and therefore develop a state of hypocalcaemia. Clinical hypocalcaemia (milk fever) may lead to coma and death in severe cases but subclinical hypocalcaemia has also been shown to have negative effects on e.g. feed intake and production and to increase the susceptibility of the cow to develop secondary diseases. The nutritional strategy applied precalving is of great importance in preventing milk fever and e.g.

Empire and Multitude - Den globala klassanalysens nya subjekt?

This essay contains a comparative analysis of Erik Olin Wrights Marxist class analysis and Michael Hardt and Antonio Negris post-Marxist class analysis as presented in their books ?Empire? and ?Multitude: War and democracy in the age of Empire?. I discuss the shift in analytical focus from state level to global level that Hardt and Negri's analysis represent and the ensuing relevance of this for contemporary class analysis. The essay also address the challenge and implications posed to class analysis by the ever increasing economic globalization, from a material production to an ever growing immaterial service economy and the decrease in state power in controlling capital and labor movement. I propose that analytical understanding of class conflict help us to a better understanding of the mechanisms and dynamics that generate social and economical inequalities and that an updated Marxist class analysis still have much to contribute to our understanding to how these issues not only shape our society but also our capacity to counteract them..

Dynamic obstructions of the equine upper respiratory tract

Dysfunction of the upper respiratory tract is a common cause of impaired performance and intolerance to exercise in racehorses and include several upper airway obstructions. The ones termed dynamic obstructions are primarily seen during physical exertion and affected horses often appear to be normal during endoscope examination at rest. The correlation between diagnoses made at rest respectively exercise is low, suggesting that an examination at rest alone is likely to be insufficient. The upper respiratory tract is exposed to great differences in pressure throughout the respiratory cycle; variations that are further altered during strenuous exercise and affect the rigidity of upper airway structures. In presence of great fluctuations in pressure, stability is achieved through coordinated and synchronous neuromuscular mechanisms. Due to nerve damage or anatomical abnormalities, these functions may be disrupted and further cause a dynamic collapse of the upper respiratory tract when pressure changes become too severe. The etiology behind the neuromuscular dysfunction is not yet fully understood.

Bild och begrepp : Heideggers läsning av Kant ur ett fenomenologiskt perspektiv

This thesis explores some key aspects of early Heidegger?s interpretations of Kant from a phenomenological perspective. In general terms, it analyzes Heidegger?s claim that Kant?s faculties share a common root in the transcendental imagination, as a critical development of motives found in Husserl?s phenomenology.More precisely, the thesis argues that the motive for deriving Kant?s first faculty, intuition, from the synthesis of imagination can be understood as an attempt to account for the receptivity of a finite subject, without yielding to a causal description of sensibility. Phenomenology shares this problem with Kant?s critical philosophy.

Syra-bas och laktat hos kolikhästar :

Ten colic horses and seven healthy horses were included in a prospective study aiming to evaluate acid-base disturbances in colic horses. Traditional acid-base methods and measurements of lactate were used to study prognosis and changes before, during and after surgery. Strong ion gap, anion gap and base excess were compared to evaluate their ability to predict lactate. Of the ten colic horses that went through surgery, seven survived, two were euthanised and one died. Significant differences in plasma lactate levels were seen between the group of survivals and non-survivals, p=0,000025. No differences were seen in pH and base excess between the two groups.

Designated Operational Entities. En legitim form av offentlig-privat governance inom ramarna för Clean Development Mechanism?

This thesis investigates the Designated Operational Entities (DOEs) under the Clean Development Mechanism (CDM) of the Kyoto Protocol. The DOEs serves as independent third-party auditors with the task of validating, verifying and certifying projects under the CDM. The majority of the DOEs are private entities. This is in line with the CDM objective of including the private sector in the climate change combat. The introduction of private entities in the role of DOEs can be questioned from a legitimacy point of view, but is corresponding to a development in international environmental governance where private actors are increasingly involved in governance arrangements.The thesis concludes the DOEs to be a form of public-private partnership and investigates the legitimacy of this form.

Follow the yellow brick road : Musikalfilmens återkomst

Youth culture and social problems associated with youth groups have existed for decades. We have chosen an explorative case study design to highlight young people's revolt against parents and society and how society has dealt with social problems of youth and how those were perceived. ?Raggare? were considered a major social problem in society. The material in the study comes from eight qualitative interviews and literature of previous research of the current youth culture.

Inflytandet av problemrepresentationer för jämställdhetsintegrering

This thesis uses the ?What's the problem?-approach developed by Carol LeeBacchi. This approach studies how the problem that a certain policy is supposedto take care of is represented. Each representation will rest upon certainassumptions and will accordingly support certain solutions while other solutionswill be considered less suitable to the problem as it is represented.The thesis therefore evaluates the competing problem representations forgender mainstreaming in Sweden. The theory chapter explores two developmentpossibilities for gender mainstreaming, based on diversity and deliberativedemocracy.

Svenska veteraners upplevelser av livssituationen efter genomförd internationell insats

The main focus of this study was to investigate how Swedish military veterans experience that events during an international service affect them after completed mission. This also includes the contact with their relatives. Secondly, this study deals with the course of the crisis, personal defense mechanisms, cumulative stress and post-traumatic stress syndrome (PTSD).The study was performed using a qualitative method and comprises individual interviews with six Swedish veterans. The responders were all men of different military positions, who participated in one or more international missions during 1993 to 2011.The results of this study show that, according to the veterans, the return back home is the most strenuous part of an international mission. With all the new experiences that an international service brings fresh in their memories, it is hard to re-adjust to the life of a civilian.In connection with the return back home, different degrees of stress reactions were also commonly seen, for example sleep disturbance, restlessness and exhaustion.

Plasmodiophora brassicae ? host and environment interactions

In this thesis, three separate experiments have been performed on different aspects of the interaction between the causal agent of clubroot, Plasmodiophora brassicae, and its hosts. In the first experiment the pathotype of the P. brassicae single spore isolate, which is currently used to construct a reference genome, has been classified using the ECD bioassay. The disease severity of infected plants was scored according to two different scales and the pathotype was determined according to three previously published guidelines. The results were compared to previous published studies describing the e3 isolate. The life cycle of P. brassicae is not well understood.

Mot mer makt? - En studie om utvecklingsländers maktsituation i Världshandelsorganisationen WTO

This thesis examines the power of developing countries within the World Trade Organization (WTO). The research question is if there is a change in the power relations between developing countries and developed countries from the establishment of the WTO in 1995 and until mid 2006, and if so, why this change is taking place? The thesis has its theoretical starting-point within regime theory and views it from a critical theoretical perspective. A multidimensional why of dealing with the concept of power is being used to answer if there is a change in the power relations? The conclusion is that there is a small change in the power relations and that the developing countries are gaining more, but limited power.

Dokumentation av en experimentell biogasanläggning

This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical devices as, flow meters, temperature   sensors, frequency converter and   more.
