The aim for this study was to investigate if it is less stressful for cow and calves in loose housing systems when separation is made so they can see and touch each other (Physical Contact-PC) instead of just hearing each other (Hearing Contact-HC). The behavior of eight cow- calf pairs (n=4 pairs per treatment) on an ecological dairy farm with cubicle housing were studied for four hours directly after separation and four hours the day after separation. The first four cows that gave birth were used for treatment PC, and the following four cows that gave birth were used for treatment HC. The only selection criteria used was that both cow and calf were healthy. Separation took place 3-4 days after birth and the calves were put separately in two different pens while the mothers were let loose into the cubicle system.

Purpose: The purpose of this thesis is to investigate potential associations between usage of the cash flow statement report and time perspective in which companies? acts and set goals. Method: Our approach is quantitative, using empirical data summarized in a statistical procedure. The result is thereafter analysed through the developed analysis model from which conclusion is drawn. Results: We have in the investigation stated that the usage of the cash flow statement report varies depending on the time perspective in which companies? acts.

During the last two decades, technology has developed rapidly. It has become a natural part of everyday life, which we today take for granted. It isn?t until the last few years that technology has quickly become a big part in the school environments. Computers, tablets and other technology is today a big part of the education and teaching.

We have made a qualitative study of what the students at Södertörns högskola use Södertörns högskola?s intranet Kurswebben for and how they experience the use of it. For this purpose we have made a qualitative interview examination with six students. The empirical material has been analysed according to our own analytic model which is based on existing usability theories and consists of the tree parts content, function and design.Our conclusion is that the students use Kurswebben mainly to keep themselves updated, download teaching material and schedules. According to our study, the students most of the time experience their use of Kurswebben as simple, but sometimes have a reluctance to visit it.

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

The idea with this study is to examine if there are a connection between how optimistic people are in relation to how stressed they feel. The result from the survey is based on materials from a questionnaire has been sent to fifty persons of varying age and sexes. The questionnaire has also been sent to students from Karlstad University but also to friends and acquaintances. The data is measured with SE- and LOT-tests. The issues concerned in which scope respondents experiences themselves stressed and optimistic and how the connection is between experienced stress and optimism in relation to results on the figure tests.

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

The European bison is a species which is no longer present in the wild fauna of Sweden. Reintroduction has been proposed in several different forums. Reintroduction is an attempt to reestablish a viable population of a species in an area to which it is native. To make such an operation successful in the long run it is essential to know the attitudes of the stakeholders involved. This study has sensed the attitudes towards reintroduction of European bison to Sweden.

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

The visions of the United Nations concerning sustainable development and conservation of biodiversity can only be realized if the human population succeeds in creating coexistence between human and wildlife. Landscape architects are able to influence on how landscapes are to be maintained and developed. The negative impact of infrastructure on wildlife has become a critical problem in Sweden and other parts of Europe. Wildlife crossings has been developed as a solution for the problems of road barriers in the landscape. The crossings are made to give animals a better opportunity to cross roads.

The background to the work bases on the consumers view around Swedish and foreign meat products, and how the attitude around the meat products is pursued in the shops. The consumers request high meat quality and security . Many consumers value local produced and ecological meat products but the price is too high. We have done verbal interviews with consumers on three different shops, where we asked questions and had dialogues around Swedish meat products where the consumers have told us their arguments and opinions about Swedish and foreign meat. The result shows that the majority of consumers consider that it is important to know that meat is produce in Sweden.

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

The interest in the significance of public health for economic growth has increasedsteadily in recent years and a clarification of this connection may be of importance forthe status of public health. Aim: The aim of this literature based study is to describewhat previous research has shown in terms of the connection between public health andeconomic growth, focusing on high-income countries. Method: The study is based ontwelve scholarly articles retrieved from four scholarly databases. Result: The resultclarify that there is a positive long-term correlation between good public health andeconomic growth in high-income countries. Good health has a positive effect onproductivity, which leads to increased economic growth.

SammanfattningSyfte och frågeställningar Syftet med denna uppsats var att undersöka hurvida en LCHF (Low Carb High Fat) kost skulle kunna vara en hälsosam livsstil utifrån hur den påverkar olika hälsomarkörer hos normalviktiga personer där en viktminskning ej har eftersträvats. Frågeställningen var följande: Hur påverkar en LCHF-kost med maximalt 30 gram kolhydrater per dag under 3 veckor normalviktiga kvinnors BMR (Basal Metabolic Rate), blodlipider, blodglukos, blodtryck, kroppssammansättning, midje- och höftmått samt deras kroppsvikt?Metod En experimentell studie har genomförts på 8 normalviktiga kvinnor mellan 20 och 35 år. Samtliga försökspersoners BMR, blodlipider, blodglukos, blodtryck, kroppssammansättning, midje- och höftmått samt kroppsvikt mättes vid normala levnadsförhållanden innan studiens start samt efter 3 veckor av en strikt LCHF-kost med endast 30 gram kolhydrater per dag.Resultat BMR sänktes i genomsnitt med 4,4% vilket var signifikant (P<0,05). HDL (High-density lipoproteins), LDL (Low-density lipoproteins) samt totalkolesterol höjdes signifikant (P<0,01) med 21%, 25% respektive 22%.
