The past and ongoing structural change in Swedish agriculture has led to an increasing number of large-scale farms. The biological factors associated with large-scale farming operations may cause increasing variability, risk and reduced yields due to sub-optimal timing and management of field operations. The theory of economies of scale suggests that largescale production may benefit from lower costs due to scale efficiencies. Thus, large-scale farms may face cost reductions in terms of long term inputs factors, e.g. agricultural machinery.

Subjektivt välbefinnande är en del av den positiva psykologin och utgår ifrån människors subjektiva bedömning av hur nöjda de är med sitt liv. Forskning inom området har visat att god livskvalitet har betydelse för högre grad subjektivt välbefinnande och andra studier relaterar till betydelsen av bra självkänsla. Studien undersökte hur gymnasieelevers kön, självkänsla och livskvalitet står i relation till subjektiva välbefinnandet. 92 elever deltog, varav 44 var män. Enkäten bestod av The PANAS scale, Satisfaction With Life Scale, The Self-esteem scale och Life Satisfaction Questionnaire.

Emotron is a company specialised in developing, producing and marketing equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes.The project is to look at Emotrons end of line test. The company has seen that at the final test-ing there is a bottleneck that restricts the outflow and prevents an increase in the number of tested products.The purpose of this project is to review how Emotrons end-of-line test works today and if there is a possibility to make the test more efficient in such a way that the quality is not at risk, while increasing the outflow of tested products.The projects first step is to look at and analyse what is causing the bottleneck at the end-of-line. When the analysis is complete, the next step is to review whether there is a possibility to solve the bottleneck and if so in what way can this be done. Emotrons most overall objective of the project is to increase the outflow of the number of tested products without jeopardizing the quality.An analysis has been made on frequency inverters, soft starters and shaft power monitors.

Android is one of the leading software platforms for the new generation of smartphones. The market for applications is growing rapidly. So to be able to compete with such large competition the applications need a solid and stable development methodology. Therefore have we created an application based on a test-driven development, to investigate if the methodology was applicable on the Android platform. The conclusion is that Android?s suitability for test-driven development is dependent on the application that is being developed and if difficulties concerning the testing framework can be avoided.

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on a balanced system using three coils. One that creates a magneticfield and the other two will sense the differences when a metallobject is in the coilsystem. This report starts out by investigating possible solutions for this specific task followed by a description of the physics that the metaldetector use.

The spatial population structure of the saprotrophic basidiomycete Tulostoma brumale was investigated at a site in south eastern Sweden. Sporocarps were mapped and collected, and somatic incompatibility tests between mycelial cultures cultivated from the sporocarps were used to identify genets. Calculations of the size and numbers of genets and their distribution were performed. The spatial distribution of the tested sporocarps and the identified genets are presented graphically in a grid. The total number of identified genets within the investigated area (1210 m2) was 27 based on 48 tested sporocarps.

Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.

This rapport handles the presence of two kinds of watermills in the Swedish landscape. The first is a small type with a horizontal shovel blade and the other a bigger kind with a vertical standing shovel scoop. The rapport seeks for information of their capacity and how long they existed as flour producing units. A important issue is how small can a brook be and still run a mill. Finally the reasons for their disappearance in one selected parish is shown..

The vegetable production in Sweden is concentrated to the very southern parts of the country. This is also were the major wholesalers are located. In recent years, there has been an extreme focus on price on the food market. As there are only a few big wholesalers and also very few food retail chains, these have a great impact on the producers. The pressure from prominent vegetable-producing countries, providing low price products, such as the Netherlands and Spain is strong.

In this paper the authors aim to examine the effects on consumers using different strategies in a campaign within social marketing. A model by Evans et al (1996) has been used in order to see the different steps in which advertising catches the viewers? attention and eventually leads to action or purchasing. However, in the case of this thesis, the intention of the chosen campaign is to change the consumers? attitudes and behavior towards alcohol.

Syftet med studien var att belysa hur motivation på arbetsplatsen kan betraktas från ett inre och yttre perspektiv, med utgångspunkt från ett antal specifika faktorer såsom samhörighet, kompetens, autonomi och kontroll i tillvaron. 126 respondenter, 99 kvinnor och 27 män besvarade en enkät som bestod av demografiska frågor, frågor kring chefens stöttande av autonomi, frågor om samhörighet, kompetens och arbetsmotivation samt ett testbatteri bestående av IMI scale, Work Extrinsic and Intrinsic Motivation Scale och Locus of Control. Studiens resultat visar att chefens stöttande av autonomi påverkade de anställdas inre arbetsmotivation positivt. Studien visar även på att det finns ett svagt samband mellan inre arbetsmotivation och tillfredsställelsen av de anställdas behov av autonomi och samhörighetAbstractThe purpose of this study was to see how work place motivation can be seen from an intrinsic and extrinsic perspective, with starting point from specific factors such as relatedness, competence, autonomy and control. The 126 respondents of the study, 99 women and 27 men, answered a questionnaire that consisted of a few demographic questions, questions about if the boss is supportive of autonomy, questions about relatedness, competence and work place motivation.

In light of the coming workforce shortage in Sweden the competition for human capital will be intensified on the market where employers compete in order to attract skilled labor. The competition will be most noticeable in the knowledge-intense industries, where the employees are seen as the companies? most valuable asset. The purpose of this paper is to examine how small knowledge-intensive companies can improve their position in the labor market by using the HR-model People Capability Maturity Model in order to affect their companies' Employer Brand. We take the basis of the theoretical framework in which we examine and identify the key dimensions of the Employer Brand concept and present the People Capability Maturity Model more closely.

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
