The complexity of the mast cell is becoming more prominent. From being the cell recognized just to contribute to allergic inflammation it is now also associated with wound healing, protection against tumor growth and in recognition and defense against a wide range of pathogens. The location of the mast cell in the barrier between the external and internal environment of the body enables the cell to quickly respond to invading bacteria, virus and parasites. Diarrhea due to Escherichia coli infection, listeriosis, toxoplasmosis, Newcastle disease and bovine respiratory syncytial virus are examples of mast cell activating diseases that can affect animals in, as well as outside, the agricultural sector. Additionally, ticks and tick-borne diseases are of concern.

In this study the author attempts to identify factors that are determinants for why some pupils in Swedish grade school have high status in comparison with their peers. The study takes on the characteristics of both an ethnographic and a literature study by comparing the findings of interviews carried out with students of a first grade class with previous research. The study identify several tools for analyzing of how status may be understood in specific situations.The study also finds that important factors for gaining high status amongst children in aschool classes might be the ability to apply access strategies to get accepted in social interactions, such as game play, have the ability to create games that are enjoyed by peers and social skills, to name a few. Overall the study shows that children's game play with each otherare crucial for their social interactions and their social position. The study also show that children that have earlier established relationships with other children in a specific group alsohave a better opportunity to establish a high status position..

AbstractDetta är en explorativ studie om processer bakom beslutsfattande. Studien innefattade 52 studenter, 20 män och 32 kvinnor. De fick genom ett frågeformulär svara på frågor kring det viktigaste beslut de fattat i verkliga livet. De flesta angav att det viktigaste beslut de fattat handlade om flytt- och resebeslut (29 %) eller studie- och karriärbeslut (44 %). Delar av frågeformulären kodades sedan utifrån kategorier från en tidigare publicerad studie kring centrala beslutsteorier och tre nya kategorier framkom; self-efficacy, self-actualization och what others will think.

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.

AbstractIn this essay I am examining the representation of popmusic with particular focus on gender and identity in two youth magazines called Kamratposten and Julia. Using the method of Norman Faircloughs critical discourse analysis I have studied ten interviews with popmusicians from each magazine based on the theorys of representations, discourses within popularmusic and queer theory. The intention with this study was to examine how popularmusic is represented in youth magazines. If the magazines were reproducing femininity and masculinity in the interviews with the musicians, and in the representation of popmusic in the magazines. And also if there were any differences and similarities between the magazines regarding the representation of popmusicians.The analysis lead to the conclusions that how popmusic is represented in the magazines depends on what the magazines wan´t to represent on the basis of their target groups and ideologies.

Bakgrund: Cancer är idag en av de vanligaste sjukdomarna i svenska samhället och klassas som en folksjukdom. Cirka 800 unga vuxna i Sverige drabbas varje år, skelettumörer, maligna lymfom och leukemi är de allra vanligaste cancerformerna hos ungdomar idag. För många unga vuxna med cancer är det till hjälp att få dela med sig sina upplevelser via bloggar för att lättare kunna hantera sin sjukdom. Att ta del av sjukdomsbloggar kan även hjälpa vården gällande förståelse och bemötande av unga vuxna med cancer. Syfte: Att utifrån bloggar beskriva individers upplevelse av att ha cancer som ung vuxen, samt att beskriva vilken betydelse bloggen har för individerna.

The purpose of this study was to highlight how women who have been victims of rape are described in discussion forums on the Internet and how the view obtained is affected by victim and gender constructions. By observing several discussion threads on Swedish internet forums, we have been able to explore how discussions and attitudes are made about women who are victims of rape and which characteristics are assigned females. This study analyzes these attitudes from a gender construction theory and a victim construction theory. Through this analysis, we wanted to gain a deeper understanding of attitudes about female rape victims and if the attitudes are rooted in victim and gender constructions. This study shows that women are often assigned responsibility to a rape if she put herself at risk and if she is assigned negative attributes such as promiscuous, as a liar or if she drinks too much alcohol.

The purpose of this study was to describe and analyze IntimatePartner Violence (IPV). How does contemporary science illustrate men as victimsand women as perpetrators in these relationships? Ten articles were presentedand analyzed in a systematic literature study. The results show that men beingabused by their female intimate partner, do exist and that they in many ways doconform to abused women. There are many underlying causes to the violence inclose relationships.

This thesis examines the subject of reference interviews and the ways librarians form an opinion of users information needs. Using literature and interviews with three librarians I look at the questions below: - Why and when are reference interviews needed? - What significance do they have? - What ideas exist about the performance of reference interviews? - Are there any differences in librarians views of the questions above compared to views in the literature? Results from literature studies and interviews show that reference interviews can be important when librarians try to find out more about users information needs. However its neither necessary nor possible to analyse all reference questions. Librarians therefore need to determine if a reference interview is needed or not.

This quantitative study explores how employee perceived efficiency within customer service is affected by standardized routines, digital tools, and motivational factors. The study is based on survey data collected from 42 employees across five customer service departments in a larger organization. The theoretical foundation integrates Weber?s bureaucracy theory, the Technology Acceptance Model (TAM), and the Job Characteristics Model (JCM), allowing for a multidimensional analysis to capture the employees' experiences of efficiency. Findings reveal a statistically significant positive relationship between perceived efficiency and both standardized routines and perceived digital tool usefulness and ease of use. Furthermore, the study identifies that skill variety and task significance are positively correlated with experienced meaningfulness, which indicates a potential mediating relationship between these motivational aspects and perceived efficiency.

To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.

This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.
