This work is about silage contaminated with slugs (Arion lusitanicus). The hypothesis was: Do slugs affect the nutritional value and hygiene quality of silage? During the winter season 2007/2008 silages were discarded in big amounts due to the contamination of slugs. Both the Swedish Farmer Association (LRF) and the National Veterinary Institute (SVA) received phone calls from farmers and animal owners about contaminated silage. The Swedish University of Agricultural Sciences (SLU) and SVA decided to initiate this project as a master thesis.

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

The purpose is to analyze if the students have any use of their computer education at a senior high school level or if there is a demand for them to proceed studying. Does the students background have any importance or is it their own motivation that makes the student advance to higher education.In this report we ask ourselves the question, if the students have any use of the knowledge gained at senior high school in computer studies at a higher level. Do the students have any chance for employment based on their senior high school grades in computer studies after graduation?  Do the schools that follow the senior high school guidelines within programming and databases give these students an advantage towards those that have not received the same fundamental education?The method used for the survey is a group questionnaire.  The questionnaire was distributed at one and the same time and then collected to examine the results. The survey results showed that students who seek work based only on their senior high school grades, received only a temporary position for different lengths of time.

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

A significant amount of a teacher?s work consists of evaluation and marking of the students, which involves a great responsibility. This essay put the teacher?s evaluation of the students in focus. Today?s course Idrott och hälsa A, at the upper secondary school level, consists of 100 points and all students take this course apart from students attending apprentice programs.

Many companies have a specific dress code in the workplace. In some companies, the code is not very extensive, while other companies have uniform requirements. What is little understood however, is what effect different staff clothing might have on consumer response in terms of satisfaction, purchase intent, attitude, interest and so on. Some limited research has shown how different levels of congruence between individuals in their marketing, and the brand they are representing, can affect customers. To avoid any wrong focus in marketing it is key to understand the knowledge gap on the potential impact the personnel in the store have on its customers.

The background to this thesis is that we know very little about lesbian and bisexual women's sexual health in Sweden, particularly in relation to sexually transmitted infections (STI) and their transmissions. An internet-based questionnaire with self-selected participants targeted to the group WSW (Women who have Sex with Women) has been implemented. An international survey on the subject shows that the WSW has sexually transmitted infections. This is also in line with the results in this study. The most common sexually transmitted infection in the survey is chlamydia which 12.3 percent have had.

The aim of this study is to examine the existence of norms in three Spanish textbooks intended for upper secondary school in Sweden. One category of norms, gender norms, is selected for analysis. The focus of the analysis is on how gender norms are represented in the textbooks. The concept of gender also includes - in addition to the relation between man och woman - ethnicity, sexuality and disability. The three analysed textbooks are Caminando 3, Vistas 3 and El Sur paso 3.

In this thesis, the results of a survey regarding grade progression between secondary and upper secondary school in a municipality in the north of Sweden serve as the starting point for a study of the experiences and expectations of a number of 16 year old girls who are in the first year of upper secondary school. The study is performed by means of focus group interviews with female pupils from the three largest upper secondary schools in said municipality in an attempt to gauge their experiences of grades, grade assessment, teacher practices and perceived differences in how boys and girls are treated. The results show that most of the girls are disappointed with upper secondary school so far. Many of them feel that secondary school was both more fun and more rewarding in a sense of learning. Their appreciation of how this more rewarding atmosphere affected their grades differed between the various groups.

The increased competition in e-commerce puts pressure on e-businesses which makes it even more important to influence the visitors on their e-commerce sites. An often overlooked marketing tool is atmospherics. With the increased focus on e-commerce from both traditional and new e-businesses this marketing tool becomes even more relevant. The aim of this thesis is to investigate how the atmosphere on an e-commerce site influences the customers' thoughts, emotions and behaviors. We examine the effects the level of stimulus on a website has on the customer's emotions, attitudes, intentions, behaviors as well as the relationship between these variables.

This thesis suggests an explanation for how it is possible for individuals living in an unsafe neighborhood to expressa highlevel of security. Araby is the district in Växjö municipality withthe highest level of insecurity. Within the district, there is acategory of individuals in security-measurements showing a high degree of security. Inhabitants living in house in Araby also seem to show a higher level of security than inhabitants in the same accommodation in other neighborhoods in the municipality.The study's purpose is to understand how individuals belonging to an unsafe neighborhood can experience a high degree of security.Qualitative data were collected from an observation in Araby and from interviews with individuals living in house in the district.Previous research has shown that security in the surrounding area depends on several factors, such as disorders, the degree of social control and personal opinions. Thestudy shows how a distinction to places and people in the district can explain the degree of security.

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

This study illuminates chosen parts of the present opportunities, in the Western World, for parents and children to choose which school the child will attend (freedom of choice), along with possible consequences that may follow. My research questions are: 1) Do tendencies show that freedom of choice leads to increased segregation, and if that is the case, how is it manifested and does it matter? 2) What relations between the student composition of schools and teachers' expectations and attitudes toward students are there? 3) Do the results from previous studies match with the result from my interviews? The methods used for answering the questions are literature studies and interviews made with six teachers who are working in two upper secondary schools in the northern part of Sweden, i.e. three from each school.The result shows that freedom of choice, regarding schools, seems to lead to student compositions that contribute to increased segregation in societies. It leads to more homogenous student compositions, in the form of ethnicity and social class, in schools in general, with consequences like different expectations and attitudes among teachers depending on the status of the composition.

Pseudopregnancy is a condition that is estimated to affect 40 % of all female dogs. Common symptoms are decreased activity level, weight gain, mammary enlargement, milk production, nesting behavior, anorexia and maternal behavior. The symptoms are displayed during metoestrus. Prolactin is one of the causes behind pseudopregnancy, but the full process is not yet known. Due to the fact that the condition affects that many bitches and often is recurrent, it is relevant to examine how the condition affects the bitch?s behavior and performance.
