Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

Bakgrund: Amning är av stor betydelse för det nyfödda barnet och mamma, både ur närings- och trygghetsaspekter. Tidigare studier om sambandet mellan förlossningssätt och amning visar motstridiga resultat; vissa studier indikerar att sectio påverkar amningen negativt medan andra studier inte visar på något samband.Syftet: Att undersöka huruvida det finns demografiska och hälsorelaterade skillnader hos mammor gällande förlossningssätt samt om förlossningssätt påverkar amningsdurationen upp till två månaders ålder.Metod: Studien har en populationsbaserad kohortdesign och omfattar n= 35250 mamma-barn par i Örebro- och Uppsala län, där barnet fötts åren 1993-2001. Statistiska analyser har genomförts med Chi-square test, binär logistisk regressionsanalys och multivariat logistik regressionsanalys.Resultat: Visade att mammor som förlösts med sectio ammade i lägre utsträckning vid två månaders ålder i jämförelse med mammor som förlösts vaginalt. Många riskfaktorer identifierades för en ökad risk att förlösas med sectio: län, hälsofaktorer hos mamma och barn, paritet, mammans ålder, rökning samt socioekonomiska faktorer. Resultatet kan hjälpa barnmorskan i hennes profession, genom att kunskap erhålls om dessa samband.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

The present study concerns a concept development of a product idea that Bengt Magnuson, associate professor, had when a heavy storm caused a widespread power failure of long duration. With a basic power-producing unit one should be able to get through a power loss. The product could also be useful for other tasks if different modules are connected, e g grass mower or snow-blower.According to the product idea the basic unit will be able to produce electric power enough for a fridge, freezer, TV, and a few electric lamps. Normally the basic unit can be used e g as a mower, when such a module is attached. An increased number of tasks would make the contraption useful and tempting for those who do not own an electrical power set in reserve.

Syfte: Studiens syfte var att deskriptivt beskriva förskrivningar av Fysisk aktivitet på Recept (FaR®) i Primärvården i Landstinget Uppsala Län (LUL) 2009.Metod: Insamlad data från förskrivare, på 26 vårdcentraler i LUL, erhölls i form av utdrag ur journalsystemet Cosmic. Data bestod av avidentifierade recept vilka sammanställdes med hjälp av variabler i Excel. I Cosmic registreras data från receptet om patienterna (kön, ålder), ordinationen (förskrivningsorsak, träningsform, typ av aktivitet, intensitet, duration), förskrivarens profession, vårdcentral samt förekomst av ordination med hänvisning till stöd av friskvårdslots.Resultat: Under 2009 förskrevs 883 FaR ut i primärvården i LUL. Detta motsvarar totalt 0,55 % av alla de som besökt vårdcentral i primärvården med en spridning på vårdcentralnivå mellan 0,04 % till 2,45 %. Medelåldern för hela populationen är 49 år (åldersspann 18-86 år).

A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.

Bakgrund: Kvinnor rekommenderas av Världshälsoorganisationen att amma exklusivt i sex månader och delvis i två år eller längre. Studier visar att amning har hälsofrämjande effekter på både modern och barnet. Trots detta är amningsförekomsten en sjunkande trend i Sverige. Råd och stöd av sjuksköterskor har betydelse för amningsförekomsten. Studier visar att mödrar som har hög self-efficacy till sin förmåga att amma, ammar i högre utsträckning.Syfte: Att undersöka om en intervention i form av evidensbaserad amningsinformation kan öka mödrars self-efficacy kring amning samt om förekomsten av exklusiv amning ökade när barnet var fyra veckor gammalt.Metod: Studien genomfördes med kvantitativ ansats och var baserad på en kvasiexperimentell före- och efter design med en kontrollgrupp (n=23) och en interventionsgrupp (n=27).

In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.

Pyometra is a common and life threatening disease of intact bitches. The disease is caused by a hormonal influence on the uterus in combination with a bacterial infection. The most common treatment is ovariohysterectomy, but several medical options are available to maintain fertility or avoid surgery and anaesthesia. Drugs that can be used for medical treatment are for example progesterone-receptor antagonists, prostaglandins and dopamine agonist. The present study focused on treatment with the progesterone-receptor antagonistaglepristone in combination with antimicrobial therapy.

Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.

Carbon sequestration through restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. The landscape of Chepareria changed from eroded, over-grazed grasslands, to a mixture of open-grazed commons, pastoral enclosures and cultivations. The aim of this study was to investigate (1) if the soil organic carbon (SOC) is higher inside the enclosures than on the open-grazed commons, (2) if SOC is affected by duration of fencing and (3) what effect cultivation of pastures has on the SOC. Estimations of vegetation cover and deep profile (100cm) soil sampling was performed on six clusters containing; (1) open-grazing (OG) (2) 1-5 years of fencing (FENCED(1)), (3) 7-10 years of fencing (FENCED(2)), (4) 15-23 years of fencing (FENCED(3)), (5) maize from OG (A(OG)), (6) maize from fenced pasture (A(FENCED)).
