Ett intressant ämne inom sömnforskningen är sömnighet, vilken ofta  mäts med subjektiva skalor som Karolinska Sleepiness Scale (KSS). Då många undersökningar görs på natt- och skiftarbetare, finns lite data för dagtidsarbetande att jämföra med. Syftet med föreliggande uppsats är att ur sömnighetsdata från förmätningen i en studie vid stressforskningsinstitutet, bilda en uppfattning om sömnighetsmönster hos dagtidsarbetande. Sömn- och vakenhetsdagböcker fylldes i av 821 personer under en vecka och resultaten analyserades med variansanalys för upprepade mätningar med inomgruppsfaktorerna veckodag samt tidpunkt och mellangruppsfaktorerna kön, ålder samt sömnlängd. Signifikanta huvudeffekter återfanns av dag, tid, kön och ålder samt interaktionseffekter av dag/tid, tid/ålder samt tid/kön.

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Motivation är en viktig komponent för att en person ska kunna genomföra en uppgift. Men hur personen handskas med uppgiften beror på vilken typ av motivation denne drivs av och i vilken grad. Tidigare forskning har visat att exempelvis stress har en negativ påverkan på motivation. Syftet med denna studie var att undersöka hur kön, ålder, antal arbetade år och stress är relaterad till inre och yttre motivation hos poliser i yttre tjänst. Deltagarna bestod av 142 personer, varav 36 stycken var kvinnor.

Syftet var att undersöka handbollsspelares generella efficacy, individuella - och kollektiva efficacy inom handbollssituationer samt nivån av utövandet. Studien bestod av två delar. Den första var kvantitativ med två frågeformulär; Schwarzers och Jerusalems Generell Self-Efficacy Scale samt Chase, Feltz och Lirggs Team Efficacy Questionnaire. Två lag från elitnivå (n=36) och två från lägre nivå (n=37) representerades. Resultatet visade att handbollsspelare på högre nivå har en högre grad av self-efficacy och kollektivt efficacy än de på lägre nivån.

Forestry and reindeer husbandry are entitled to use the same land for their operations. For this reason, conflicts occasionally arise between them. Soil scarification is a forestry operation which has a negative effect on the occurrence of reindeer lichen. Reindeer lichens are of crucial importance to reindeers and reindeer husbandry, especially in the winter when reindeers primarily feed on different lichen species (Cladina spp. and Cetraria spp.).

ABSTRACTThe aim of this study was to examine the relationship between job satisfaction, birth order and sensation seeking. The sample consisted of 179 jobholders in four different organizations in southern Sweden, with an average age of 44 years (SD = 12,12). A questionnaire consisting of three parts was used to map out and measure the participants? family background, birth order, job satisfaction and sensation seeking. The study showed no significant relationship between birth order and job satisfaction (p = 0,127).

Syftet med studien är att öka kunskapen om män som har en impulsiv aggressivitet riktad mot sin partner, och om männens brister i affektmedvetenhet (alexitymi) samt deras förmåga till empati och om de skiljer sig i dessa aspekter från män som söker hjälp för relationsproblem på Manscentrum. 20 män med våldsamt beteende och 20 med relationsproblem fyllde i Aggression Questionnaire-Revised Swedish Version (AQ-RSV), Toronto Alexithymia Scale (TAS-20) och Interpersonal Reactivity Index (IRI). Resultaten visade ett positivt samband mellan aggressivitet och alexitymi i hela populationen och ett negativt samband mellan alexitymi och empati. De våldsamma männen var också aggressivare enligt AQ-RSV än de med relationsproblem, men inga andra skillnader var signifikanta. De män som hade erfarenhet av våld i ursprungsfamiljen hade ett starkare samband när det gäller aggressivitet och alexitymi.

Construction of Identity and Charismatic Leaders deals with fundamentalism and Islamism within the United States, emphasising on similarities between fundamentalists and Islamists. The term "fundamentalist" is here referring to Christian extremists, while "Islamist" refers to the Muslim counterpart. The purpose of the essay is to make North American fundamentalism and Islamism comprehendible on a larger scale.In order to show similarities between these groups when it comes to values, structure and commitment to their tasks, it is important to understand the nature of the religious devotion.Analyzing the similarities of the two groups enables construction of general criteria for how anthropology of religious extremists can be outlined..

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

Studiens syfte är att undersöka hur stor del av de män och kvinnor som döms till fängelse som har uppmärksamhetsstörning (Attention Deficit Hyperactivity Disorder, ADHD). Den skall även besvara frågan om huruvida det finns skillnader mellan könen i prevalens, samt om det finns korrelation mellan ADHD och Antisocial personlighetsstörning (ASPD). Metoden som används är självskattningsformulär som är välbeprövade inom detta område, Wender-Utah rating Scale (WURS) och Mini Neuropsykiatrisk Intervju (M.I.N.I.). Formulären besvarades av 49 fängelsedömda män och kvinnor, vilka var inskrivna på kriminalvårdsanstalter i mellansverige. Resultatet av studien visar att en hög andel av den aktuella populationen har både ADHD och ASPD.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: Can nutritional support contribute to the healing of pressure ulcers in elderly patients?Author: Anton Kinnander, Sandra SmidelikSupervisor: Elisabet RothenbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 12-04-11Background The number of elderly patients with co-morbidity is increasing in the western world. It is therefore reasonable to predict increasing incidence and prevalence of pressure ulcers. One study, published 2009, found that as many as 59 % of geriatric patients within the Swedish health care system had developed pressure ulcers. Symptoms vary from mild erythema to severe deep tissue damage and development of pressure varies from hours to weeks.

My work deals with large scale design of the urban fringe. The thesis is divided in three parts; ?Current viewpoints?, ?Infra City ? conditions ? and ?Infra City ? project?. In the first part, I go through the history of trade shortly. Then I discuss the concept of nature, which ends up in a linkage between natural science and aesthetics in landscape architecture. The link between those two makes a project stronger and more multifunctional. The object of my case, Infra City, is a mall situated north of Stockholm on both sides of the E4 motorway going to Arlanda airport.
