Miljöanpassade tjänsteresor. En kvalitativ studie av privata aktörers resepolicy
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.
Hästar i skrämmande situationer : en jämförelse mellan hanterad respektive fri habituering
In connection with riding and handling of horses, many accidents that can cause severe injuries to both horses and humans are existent. The cause is in most cases that the horse is frightened. The horse's fear also affects its usefulness and it has been shown to have adverse effects on the horse's welfare. To increase safety and improve the welfare of both humans and horses, it is important to find appropriate training methods to reduce the fear of horses in frightening situations. This experimental study compares handled habituation to free habituation.

High blood pressure is one of the greatest risk factors to develop cardiovascular diseases, which is the leading cause of death worldwide. Milk is a nutritional food product and previous research suggests that low fat dairy products may have blood pressure lowering effect.Objective: The aim was to examine the scientific basis of how low fat dairy products affect blood pressure.Search strategy: Twelve searches were conducted on PubMed and Scopus, where the chosen search terms were combined to produce a broad search as possible in the particular area. The search terms used were dairy, dairy products, milk, blood pressure and hypertension.Selection criteria: Studies on normotensive or hypertensive individuals who received low fat dairy products were included.
Naturreservat : en bra naturvårdsåtgärd för att bevara enskilda arter och/eller bevara den biologiska mångfalden?
The examination of the adequate nature conservation methods in a natural reserve, to conserve a specific species and / or increase biological diversity is the subject of this study. This work is based on four species, that can be found during the Spring season, liverleaf, wood anemone, brimstone and woodpecker. The incidence and availability is studied and closely observed for these species in twenty forests, i.e. ten forests which are nature reserves and ten forests with the similar characteristics as the nature reserves habitat, but are not nature reserves in Gnesta mucipality, Södermanland. Measurements of the tree crown and the diameter of the tree trunks where noted to study how these factors could affect the outcome of the abundance and incidence of the four species.

Vilka faktorer inverkar vid valet av transportföretag? : En fallstudie om företagskunders resonemang och prioriteringar vid köp av transporttjänster och val av transportföretag.
During the last couple of years the focus for many businesses have moved from just being price oriented to include such factors as quality, flexibility, service, delivery precision and environmentally friendliness. The shift in viewpoint arises from the increasingly competition on the market and the hard economic atmosphere. It has become more important to differentiate the company and its products to be able to increase market share. The purpose with this master?s thesis was to get a better understanding on how companies (customer to DHL) are reasoning and prioritizing when choosing Swedish carriers.
Library anxiety: en undersökning av psykologiska aspekter kring studenters upplevelser av sitt universitetsbibliotek
This essay investigates the psychological aspects in students' experiences of their university library and the information seeking process. Focus of the investigation is library anxiety, a kind of fear towards the university library with cognitive, affective and behavioural aspects. Twenty students at Uppsala university, who was about to conclude or recently have concluded an academic essay, were interviewed about their experiences of the university library, Carolina Rediviva. Five respondents stated experiences of fear, anxiety and apprehension in the library and it is on these informants that the greater part of the analysis and discussion draws. The essay suggests a model of library anxiety where outer environmental aspects of the library, such as the library environment, roles and routines of the library and library staff, interacts with inner personal aspects of the individual such as personal experiences, intellectual capacity and sensitivity to stress and anxiety.
?Vi läkare är inte utbytbara!?: - en studie om identitetsskapandevid fusioner i sjukvården

Health care units are forced to make some structural changes in order to become effective and efficient. As a result merger and acquisitions has become a part of the health care sector, and seems to be an increasing phenomenon. Mergers and acquisitions have mainly been studied in the industry.
Är en schimpans bättre på att skapa avkastning än en professionell fondförvaltare? : En jämförande studie om historisk avkastning av förvaltade fonder och slumpmässigt genererade portföljer
Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Karlshamn-Wislanda Jernväg : Maktelit och nätverk i Karlshamns stad vid banans tillblivelse 1855-1874
The aim of this essay was to describe the power elite of the Swedish town Karlshamn, and its influences on the local political process before the realization of the narrow-gauge railway Karlshamn-Wislanda-Jernväg. During the mid 19th century, a revolutionary period began in the Swedish pre-industrial epoch. The political and institutional regulatory frameworks were disassembled and restructured, away from protectionism and centrally controlled administration, for the benefit of free trade, local self-government and liberalism. The changes were carried through during times marked by a drastic increasing native population and upcoming demands for adjustments to meet the growth of the industrial-, trade- and labour markets. An essential industrial development factor was the building of the national railway network, which started after some important decisions in the Swedish Riksdag during the 1850´s.
Revolutionen är en man : Genus, nationalitet och nyhetsvärdering i de svenska mediernas rapportering om den arabiska våren
In this study we examine four Swedish newspapers? visual coverage of the Tunisian and Egyptian uprisings in 2010 and 2011 ? commonly known as the ?Arab Spring Revolution?, the ?Jasmine revolution? and in Sweden also the ?Women?s revolution? ? focusing on three main perspectives: news values and framing, postcolonialism, and gender.By means of a comprehensive content analysis and an in-depth semiotic analysis, the purpose of this study is to investigate how Swedish written media frames the revolution and its initiators and partakers through news photographs, headlines, lead paragraphs and photograph bylines, and to determine whether or not it reproduces earlier trends of media coverage and framing of non-Westerners and non-Western societies.The purpose of the extensive content analysis is to attain data for empirical research of the visual portrayal of the uprisings? first twelve weeks in Sweden?s four largest newspapers Dagens Nyheter, Svenska Dagbladet, Aftonbladet and Expressen. The analysis reveals that episodic framing is regularly used in all four newspapers, and that media demonizes Tunisians and Egyptians by constructing them as a brutal, uncivilized and threatening group which almost exclusively consists of men, and whose members are neither quoted nor named. It also shows that women are symbolically annihilated by media and that the very few women who do occur are gender stereotyped in accordance with established media conventions and postcolonial tradition, with the interesting exception of women being quoted to a larger extent than men. The analysis furthermore confirms the low occurrence of female journalists in Swedish foreign reporting, as well as demonstrates that the gender of the journalists does not influence what types of stories are written or how they are framed.The variable frequencies obtained from the content analysis provide indicators which are subsequently explored in the semiotic analysis of four news photographs.
Product Return Process - Developing a Web-Based Return Form to Improve the Information Flow between an Apparel Company and Its Retailers
Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more reactive and also has less visibility.
Aktivitet, läggnings- och resningsbeteenden, tillväxt samt renlighet hos kvigor i liggbås respektive djupströbäddsbox :
The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter.
The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.
