Konditionstester i rehabiliteringssammanhang : - En litteraturöversikt
During the past few years there has been an observed decrease in physical fitness within different patient groups. As a part of the rehabilitating physiotherapy treatment it is important to acknowledge the physical condition of the patient. Physical fitness testing might be difficult due to physical limitations within different patient groups. A broad range of exercise tests is therefore of importance in clinical practice. The aim of this overview was to describe exercise tests used in rehabilitation contexts, and to define areas of use and restrictions.

Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the manufacturing process, manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..
Agroprotein som fodermedel till slaktkyckling
Destillers dried grains with soluble (DDGS) is a by-product when producing ethanol. DDGS from wheat has a high crude protein content and a good amino acid profile, which makes it an interesting feed ingredient for poultry. The disadvantage of feeding DDGS from wheat to poultry is that it also contains a high fiber content that chickens don?t have the ability to break down. Lantmännen Agroetanol has developed a new protein feedstuff from DDGS by extracting wheat protein from DDGS, the product name is Agroprotein SD.
Hur rör sig polisens tjänstehundar? : en pilotstudie gällande tjänstehundars rörelsesymmetri mätt med tryckmätningsmatta
SammanfattningBakgrundDet är i Sverige svårt att tillgodose behovet av cirka 450 tjänstehundar och gällande hälsa är uppfattningen bland användarna att hundarnas fysiska hållbarhet blivit sämre. Med hänsyn till att det lider brist på tjänstehundar och att de tas ur tjänst tidigare än önskat vore det av stort värde att kunna förlänga en polishunds tjänstgöringstid. Ett sätt att förverkliga detta kan vara att använda undersökningstekniker vilka tidigt kan fånga upp lindriga förändringar i rörelsesymmetri, förändringar som kan vara ett första tecken på smärta. En tryckmätningsmatta kan registrera små förändringar i hur hunden belastar sina ben, förändringar som är svåra att se med blotta ögat. Det kan därför vara av intresse att ta fram ett normalmaterial för tjänstehundar så att det med tryckmätningsmattans hjälp tidigt går att upptäcka om en stoisk tjänstehund har ett förändrat rörelsemönster.Syfte & hypotesSyftet var att använda en tryckmätningsmatta för att skapa ett normalmaterial för en tjänstehundspopulation gällande parametrar registrerade med tryckmätnings-mattan.
Geotermisk fjärrvärme i Gunsta
Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW.
To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

ECG-Screening for young elite athletesAbstractBackgroundSudden cardiac death (SCD) during physical activity is a frightening and emotional tragedy that draws huge media attentions when it occurs. Fortunately it is a relatively uncommon occurrence but happens nonetheless to young athletes who often seems to be in perfect health. SCD is used as a term for sudden unexpected complications on the cardiovascular system that leads to a deadly outcome normally within the first hour of onset of symptoms and the cause is some sort of underlying cardiovascular disease that gets triggered by physical activity.Normally athletes gets divided into two groups dependent on age, over and under 35 years, and this studies focus is on the younger group since it is often during this period athletes are at the elite level. It is also in this category the most unexpected sudden deaths occur that is not due to coronary atherosclerosis, which is the dominant cause of death, and drastically increases, for people over 35 years old.AimThe aim of this study was to scientific and unbiased analyze peer-reviewed clinical articles todescribe the pros, cons and cost to implement an ECG-screening as a standard before physicalactivities for specifically defined elite athletes.MethodA systematic review was performed and after all data collection 21 articles was chosen to beused as a base for both background and analyze. At the end 10 articles was fulfilling the criteria to be used at the analyze and later the results.ResultsThe implementation of ECG-screening has reduced SCD in Italy by 89 % between the years 1979-2004.

Tame animals in the wilderness : livestock grazing around summer farms in Jämtland, boreal Sweden 1800-2011
The forest and mire landscape surrounding the north Swedish villages have been of fundamental importance through time for the farmers. In the Scandinavian summer farm system the forest and mire pasture was used to its full potential. The system consisted of smaller summer farms some kilometres from the main farm in the village, and were the livestock grazed in the forest around the summer farm. The livestock affect their environment, and grazed forests generally contain a higher biodiversity than an ungrazed forest. The overall aim of this thesis is to understand the impact of livestock grazing on a northern forest ecosystem over a long time period.

Dämplindningens inverkan på spänningens kurvform i en vattenkraftsgenerator
Harmonics are a well-known problem that has to be dealt with in the design of thegenerator. Internationally accepted standards limits the amount of harmonics allowedin the no-load voltage. These limits can be difficult to fulfill with integral slot winding,where the number of slots per pole and phase is an integer. The presence of thedamper winding often makes the problem with harmonics even worse and harmonicswith frequencies of order 6q±1 arise with significant amplitude. How the damperwinding is designed affect the content of harmonics in the no-load voltage and the aimwith these ? has been to investigate in which extent design of the damper windingaffects the contents of harmonics.Simulations with the 2-D finite element method have showed that if the damper barsis centered in the pole shoe, the amplitude of the harmonics of order 6q±1dependsboth on the ratio between the stator slot pitch and damper bars slot pitch and if thedamper bars are connected between the poles or not.If the damper bars is displaced with ¼ stator slot pitch alternately, the amplitude ofthe harmonics of order 6q±1 is reduced and the influence of the ratio between thestator slot pitch and the damper bars slot pitch will vanish.
Energibolagens framtida datainsamling
The Swedish energy companies have several different systems for data collection
of the energy consumption of their clients. Often computerized remote meter
readers are put in practice in order to register the energy consumption of
large companies. The majority of household clients, however, are read off by
the assistance of manual methods.
Household power consumption is read off once a year. As a result, these clients
are not debited for their actual consumption; their invoices during the year
are the result of estimations. At times when the electricity supply system is
highly loaded, electricity is more expensive.

Stockholms Universitet, Instutitionen för journalistik, medier och kommunikationJMK, Karlavägen 104Box 27 861, 115 93 STOCKHOLMTel: 08-16 20 00Titel: CCTV och Al Jazeera ? likheter och skillnader i de internationella nyhetsprogrammen Title: CCTV and Al Jazeera ?similarities and differences in the international news programsFörfattare: Hanna Strid, hanna.strid@gmail.com, Marta Kaszuba, marta.kaszuba@hotmail.com.Handledare: Christian ChristensenC-uppsatsHöstterminen 2013This essay aims to identify what similarities and differences there are between news broadcastings from Chinese CCTV and Al Jazeera English which has its national headquarters in Qatar. When national channels broadcasts internationally, it is interesting to see what they choose to convey as that day's news flow and how to represent their country. It can depend on many different things such as structures of media ownership in the country and cultural context. The research methods used have been empirical studies and comparative analysis of a total of ten broadcasts of the largest daily newscasts on both channels, both news programmes are called the News Hour.
