Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.

This paper aims to describe the geographical changes of Swedish international aid politics since 2007, which was the year the new aid reform of decreasing collaborating countries, came up. To decrease the number of aid receiving countries due to efficiency is not a new idea within Swedish aid politics, but Sweden received criticism from the (DAC) Development Assistance Committee, saying Sweden was active in too many countries, and the government established a policy to decrease the amount of countries given aid. Despite the government?s recent work, science has shown on a failed country focusing. This is followed up in the paper trough examination of statistics to measure the extent of the reduction.

This bachelor thesis is intended to gather the knowledge and experimental data on the winter wheat crop production relevant for Swedish conditions, with focus on sowing time, row spacing and seed rate. This essay is a literature study with a minor component based on interviews with farmers producing winter wheat. The work is divided into a background part where basic knowledge of winter wheat physiology, development and environment interactions are described and one part where results of field trials studies are presented. Optimal date of sowing winter wheat depends on annual weather variations. Because it is difficult to forecast the weather the choice of sowing date should be based on weather statistics, production experience and previous results depending on sowing date.

Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. Kongsbergs Automotive has developed a new gear shifter platform (Shift-by-Wire) that is sold to Alfa Romeo and used in of their car models. However, the company is not pleased with the components sound quality, therefore the main purpose of this thesis is to develope a number of concepts that is supposed to enhance these NVH-aspects.To get an understanding of the problem an analysis of the causes of the emitted sound has been done parallell to a product decomposition, function decomposition and a Ishikawa-diagram. Together with these methods has a litterature study been performed to get familiar with the physics of an impact and especially the emittment of noise.

The objective with this essay is to establish the benefits of inserting media as an obligatory topic in the upper secondary school. In order to succeed with this I will not only type this essay I will also produce a medial production in the form of a film.  I have interviewed two senior masters on Södertörns College where I have reviewed different questions that relate to the matter's weight in school values and the society. In the study I will also reflect over existing research within the area and to link these to the issue and those interviewed opinions. In the film I also present statistics within the communication technology's increase and an explanation how one obligatory topic becomes an obligatory topic..

Title: A Business Perspective on Reducing the Climate Impact from Tetra Paks Transportations of Goods. Authors: Pär BerglundSebastian Lyngström Supervisors: Lars J Nilsson, Environmental and Energy Systems, Lund UniversityNils Månsson, Department of Business Administration, Lund University Problem Analysis: Increased awareness concerning climate change will put pressure on companies to reduce their climate impact. Problems arise when trying to reduce the impact from transportations due to companies? limited control on forwarding agents and difficulties measuring the emissions. Purpose: From a business perspective, this report will enable a reduction of the climate impact that arises from Tetra Paks transportation of goods.

Syftet med denna studie var att undersöka hur fetma/övervikt påverkar lederna och utveckling av artros och hur sjuksköterskan kan informera, undervisa i förebyggande syfte. Metoden är en litteraturstudie. Tolv vetenskapliga artiklar granskades enl. Polit et al (2001) kriterier för vetenskaplighet. Därefter inleddes analysen där fyra huvudteman framträdde: BMI och påverkan på lederna, Smärtpåverkan vid artros, Genusskillnader vid artros och övervikt samt Sjuksköterskans undervisande roll.

The Swedish social insurance agency provides financial support for families and children, but also for people with work injury, illness and at old age. During 2012 they saw the amount of notifications of insurance increasing in Sweden, which is a development that cost our society a great deal of money. With the aim to pursue a sustainable development I have therefore devoted this project to wellness and stress management within preschool.The employees of preschool are often dealing with a lot of stress, due to the big groups of children that causes high noise and sound levels. The high noise and sound levels is a contributor to stress which additionally can damage the health and cause impaired hearing loss. About half of the people around their forties until the age of retirement have difficulties understanding speech in large groups.The purpose of this project has been to investigate the causes of negative stress for my target group, women between 30-60 years old who works in preschool.

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.

Return handling is often regarded as a slow and complex process. Studies have shown that it is not unusual for a return to cost up to nine times as much as a standard outbound delivery. An efficient return handling process is therefore essential to all competitive companies dealing with logistics. This report investigates, analyzes and gives suggestions on development with the purpose to improve the return handling process at LensLogistics AB in Kista, north of Stockholm, Sweden. The study has been conducted from a deliberately practical point of view in order to suggest improvement suggestions possible to implement and thereby change the entire return handling process.

Myxomatous mitral valve disease is a common disease in older dogs of small- to medium-size breeds. The mitral valve, and less commonly the tricuspid valve may be affected which causes them to leak blood from the ventricle to the atrium of the heart during systole. With increasing severity of mitral valve leakage the forward stroke volume ejected into the aorta decreases, which may lead to an increase in blood pressure in the pulmonary vein resulting in pulmonary edema. A decrease in cardiac output may lead to a decrease in blood pressure, but the body may respond in order to normalize the blood pressure. Franzén showed in 2007 that the systolic blood pressure was increased in dogs with severe mitral insufficiency.

Obesity is the most common nutritional disorder, and is defined as an accumulation of excessive amounts of adipose tissue in the body. Obesity is a condition where an animal exceeds its optimum body weight by more than 10-25%. Risk factors associated with obesity may include breed, age, castration or high energy intake relative to energy consumption. The consequences of obesity are believed to be metabolic and hormonal changes, as well as cardiovascular and respiratory diseases, orthopedic problems, tumors and premature death. Prevention and early detection of obesity leads to better health care.
