Apart from recognizing and neutralizing threats, antibodies also have the ability to regulate immune responses against their specific antigen. IgG administered together with erythrocytes is well known to induce >99% suppression. This has been used to prevent haemolytic disease in new-borns since the 1960's, but the mechanism behind it is still not completely understood. The effect on the primary response is well established, but its influence on induction of immunological memory is still heavily debated. In this study adoptive cell transfer of splenocytes to irradiated mice was used to survey the effect IgG has on induction of immunological memory without disturbance from the primary IgG response.

The purpose of this report was to investigate how the abiotic factors (temperature, pH, nutrients, oxygen levels and water content) would affect the decomposition of oil-contaminated soil and how a variance in structured soil would affect the decomposition-rate. A minor field-study was made and soil where structured in five different ways (one was a default pile and was used as a reference). The study took place over 137 days and three samples were taken (start, middle, end) and analyzed for aromatic and aliphatic compounds. The result of this study shows that there is a significant difference between all methods for the aliphatic compounds and no significant difference for the aromatic compounds. The abiotic factors that affect decomposition vary from organism to organism, depending on what type of environment it will function the best.

The vast majority of parents want their children to succeed and become successful in one way or the other. The very first is that the child will graduate from school. In today?s society which is characterized by career-driven parents, especially mothers, one wonders if somewhere along the way parents are prioritizing their own careers over their children?s school achievements. This might be true in some cases, but in others it could merely be that parents are expecting more from their children?s future.

Today's society is characterized by constant changes. In order to adapt to the development, organizations must continuously come up with innovations and invest in new projects. As a result, the responsibility of organizations' leaders has increased. Parallel with this development, more and more firms incorporate mindfulness in the organizations, and many managers choose to practice mindfulness themselves. This case study is based on interviews with business leaders that have completed a course in mindfulness.

AbstractThis research is about pre-school children?s conceptions of the river and the water environment. The aim of this study was to apply a new teaching method based on the outside learning, as well as to test the method and see if it works, i.e. if children get more knowledge this way compared to ordinary methods like teaching in the class-room which involves showing pictures and discussion of them.The main questions in this study were how children get new knowledge through outside learning and how effective this learning method is, i.e. how much they noticed and learned about the river and the water environment as a result of that outside observation.

With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

This essay aims to explain the fluctuations in the Swedish transition rate to higher education between 1923 and 2002. With theories of human capital, and screening, as points of departure, seven variables are selected and their correlation with the transition rate investigated by use of graphs and tables. The variables are unemployment, youth unemployment, the supply of academics, cohort size, number of high school graduates from programs preparing for ensuing studies, relative wage trends for worker categories with differing levels of education, and structural phase. Results show that no single variable nor the theories of human capital or screening can explain the fluctuations in transition rate in full. Instead I propose a theoretic model which amalgamates the above and places risk aversion as the driving force behind the individual?s educational decision.

Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

The aim of this study is to explore how sports journalism can include and/or exclude athletics from a national community. This study put emphasis on finding patterns from articles by Swedish sport media on non-ethnic Swedish athletics. The theories central to this study are ethnicity and nationalism, as these concepts contain reflections on why certain groups of people are excluded and/or included. Norman Faircloghs critical discourse analytical model has been selected for the study method that analyzes texts in three levels: the text level, discursive practice and social practice. Four non-ethnic Swedish athletes have been chosen to explore how they were portrayed in the media.

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.

SAMMANFATTNINGNatriuretiska peptider är en är en grupp proteiner som via natriuretiska, diuretiska och vasodilaterande egenskaper reglerar vätskehomeostasen i kroppen (Levin et al, 1998). De frisätts bland annat när hjärtmuskelcellerna utsätts för stress och kan fungera som biomarkör för att utvärdera hjärtsjukdom. Analysering av typ B natriuretic peptide (BNP) i blod kan komma att vara till hjälp för den praktiserande veterinären vid diagnostisering av hjärtsvikt och även vid uppskattning av grad av hjärtsjukdom. Det har även visat sig att BNP kan användas för att uppskatta prognosen hos hundar med kronisk klaffdegeneration (Chetboul et al, 2009; Moonarmart et al, 2010).Kronisk klaffdegeneration är den vanligaste hjärtsjukdomarna hos hund och drabbar fram för allt små till medelstora hundar från medelåldern och uppåt (Kogure, 1980). Atrioventrikulärklaffarna, vanligtvis mitralis, blir nodulärt förtjockade med inlagring av glukosaminoglykaner och fibrosvävnad vilket leder till klaffinsufficiens.

Sexual dysfunctions concerning women with multiple sclerosis (MS) are common. Since the disease preferably affects young individuals when establishment of family occurs, the result of these problems have a great impact on the individual and her family. The purpose of this literature review is to throw light upon these problems and respond the questions if the nurse may be the right person to give sexual counselling and in which way this may be done. The theoretical framework was Antonovsky´s concept "sense of coherence". The result is presented in four themes: bodily aspects, social aspects, information/counselling, and practical implications for nurses.

In today?s society there is a discussion regarding students? level of knowledge and personalisation. The classrooms consist of heterogenic groups of students with different learning needs and levels of knowledge. The purpose of the present study is to find out how the students who participated perceive the teaching of English as an additional language with regards to personalisation, and how they believe differentiation can help develop and deepen their learning. This study has been conducted using a qualitative method with interviews as the core, complemented by observations. The results have been analysed and interpreted hermeneutically. The results show that those students who have a positive attitude to English education, irrespective of their grade, are those who see the benefit of knowing English outside the classroom, and thereby create a connection between reality and studying English.

This study deals with the complex phenomenon of occupational health. There is knowledge of how a good work environment should look like, but despite this, many employees experiences ill health in the workplace mainly in the form of neck and back pain. This study is a case study conducted in a high-risk workplace. The overall purpose was to describe and analyze the health situation of a specific company with neck and back problems. Mainly, eight interviews had been used as the data collection method, but additional observations had also been implemented.
