Sleep is a vital part of life. Even so a lot of the mechanics regarding sleep is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are largely un-known.

During sleep the majority of the body?s production of anabolic hormones is produced and sleep is a general anabolic state of being. It has been to our recognition that a powernap is 4-6 times more effective when it comes to sleep intensity than the last 1-2 hours of a traditional eight hour sleep. With this in mind, and that elite athletes worldwide often sleeps in between their training sessions. This study has tried to prove a hypothesis which comes from the assumption that you can recover and perform better during times with intensive periods with better distribution of your sleep.We have in this study let three test subjects take part of a six week long program with two different training periods for legs.

Sleep has a substantial effect on health status where good sleeping habits proves positive on learning. The aim of the present study was to map the views and perceptions of sleep and its effects on health and school performance on 12-year olds. The goal is to visualize these views to give teachers the possibility to better plan the education in concordance with the students? abilities. The study is based on qualitative semi-structured interviews where 12 students aged 12 have partaken.

There is strong evidence that cognitive-behavioural therapy for insomnia (CBT-I) is effective. The aim of this study was to compare 7 group-sessions of mindfulness-based cognitive therapy for insomnia (MBCT-I) with 3 group-sessions of CBT-I, on sleep measures and sleep related psychological processes, such as pre-sleep arousal, thought control strategies and mindfulness. Participants (N = 44; age 18-66) with long term insomnia were stratified and randomized into waiting list, MBCT-I and CBT-I. Significant improvements were seen in both groups, compared to waiting list, for instance on insomnia severity, sleep latency and restorative sleep. Small improvements on psychological processes were also found in both groups.

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

Vårt syfte med denna studie var att göra en psykometrisk utvärdering av frågeformulären PSAS-C (Pre sleep arousal scale) och APSQ (Anxiety and preoccupation about sleep questionnaire). Teoretiska modeller har kommit fram till att kognitiv uppvarvning och förvrängd subjektiv perception av sömn skapar oro som kan bidra till utveckling av insomni. För att fånga upp oro vid insomni används idag två frågeformulär, PSAS-C och APSQ. Deltagare från en svensk longitudinell studie (n = 2333) ombads att svara på de två formulären. Båda skalorna visade på en god begreppsvaliditet och intern samstämmighet.

Tumour development occurs to a large extent because of dysregulation of the cell cycle. Of particular importance are defects occurring in the G1 phase. The reason why G1 is critical is because of the influence of several signals (external signals as well as cyclins and cdks) on this stage. The G1 phase can be divided into two parts, G1pm and G1ps. Each part has its ?own? restriction point which needs to be passed in order to progress to S phase.

According to Swedish tax legislation, investment funds are taxed differently depending on if the are Swedish or foreign. The difference between the investment funds lies within the taxation of received dividends and the opportunity to shift the liability of tax of received dividends on to the funds shareholders. This measure is only available to Swedish funds. The question in this thesis is whether this difference is discriminatory against foreign investors and therefore constitutes a forbidden restriction against the free movement of capital stated in article 63 EUF Treaty.The European Court of Justice (ECJ) has given several preliminary rulings on this type of legislation and its compatibility with the principle of free movement of capital. It is not compatible with the free movement according to the court.

Människors allmänna välbefinnande och livskvalitet påverkas av deras sömn.    Sömnproblemen ökar och resulterar i ökade kostnader för den enskilde, arbetsgivarna och samhället. Syftet med litteraturstudien var att beskriva effekter av sömnhygieniska åtgärder riktade till individer inom hälsovården med primär insomni. Resultatet visade att en kombination av åtgärder utifrån personliga behov gav bäst resultat men också att det rådde begreppsförvirring runt sömnhygieniska åtgärder och deras effektivitet. Fördjupad kunskap behövs vad det gäller de enskilda sömnhygieniska rådens effektivitet.

Kognitiv beteendeterapi för primär insomni är inte lika effektivt som KBT för annan problematik. Behandlingen har mest fokuserat på förändring av sömn och bortsett från andra faktorer som kan bidraga till problematiken. Denna studie syftade till att utvärdera effekten av att addera en intervention mot en ytterligare faktor, nämligen oro, till behandling. Studien hade en single subject-design med två betingelser, med och utan oroshantering, för- och eftermätning och sju deltagare. Resultaten tyder på att metoden konstruktiv oro tillförde bättre utfall på sömn, oro och daglig funktion.

Aim: The aim of this study was to examine health professionals´ experiences of giving advice regarding sleep to parents of infants and to perform and evaluate an intervention in the form of introducing information about the sleep of infants.Method: The study was designed as an intervention study with a qualitative approach where data was collected from two focus groups in the form of interviews. The intervention consisted of the information material Sugen på sömn. There were five participants whom three of them participated in the second interview. The interviews were processed by content analysis.Results: Health professionals´ experience of giving advice on sleep was summarized in three themes. The experiences of giving advice in interaction with parents, health professional themselves experienced the power to influence the parents with the advice they gave, while the parents' previous experience and knowledge impacted on how the advice came into practice.
