Data warehouse system Àr nÄgot som har vÀxt fram under 1990-talet och det har implementeras hos flera verksamheter. De kÀllsystem som en verksamhet har kan integreras ihop med ett data warehouse system för att skapa en version av verkligheten och ta fram rapporter för beslutsunderlag. Med en version av verkligheten menas att det skapas en gemensam bild som visar hur verksamhetens dagliga arbete sker och utgör grundinformation för de framtagna analyserna frÄn data warehouse systemet. Det blir dÀrför vÀsenligt för verksamheten att de framtagna rapporterna hÄller en, enligt verksamheten, tillfredstÀllande god datakvalitet. Detta leder till att datakvaliteten hos data warehouse systemet behöver hÄlla en tillrÀckligt hög kvalitetsnivÄ.

To increase the knowledge about the growth of hazel (Corylus avellana)and size distribution of the shoots, circumference and stem diameter wasmeasured in a total of 54 clones in two areas in Östergötland. Further, thewidth of growth rings was determined for separate years. The diameter ofthe stems was measured both out from the centre of the stem andperpendicular to the first measure. The stems showed only a weaktendency to have an oval shape (with the longest side outwards from thecentre). The growth model did not improve when the degree of sunlightof clones was taken into the account.

The biogas plant KungsÀngens gÄrd, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

Fritidshemmens arbete med vila och rekreation befinner sig i skuggan av de ?vriga delar som ?terfinns i fritidshemmets uppdrag. ?tminstone r?der det ett forskningsgap g?llande hur l?rare i landet arbetar med dessa begrepp i praktiken. Genom v?r kvalitativa intervjustudie str?var vi efter att kunna bidra med mer underlag till forskningsf?ltet g?llande arbetsg?ngen kring vila och rekreation utifr?n ett policy enactment-teoretiskt perspektiv.

During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of HammerstaĂ„n in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net called strömöversiktsnĂ€t (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.

The purpose of this study was to examine what students themselves think about using computers in school. The study was conducted in a school in central Sweden. The students in focus were students with reading and writing difficulties, dyslexia or language difficulties such as an other native language. A total of eight students were interviewed. The interviews were analyzed using thematic analysis.

Dropout among youth players is a problem in Swedish icehockey. Leaders in youth hockey teams work closely with players on an almost everyday basis during season and have a big influence on players and their activities. This study aims to identify possible reasons for dropouts by interviewing coaches and leaders in icehockey clubs. A total of eight coaches and leaders in different ice hockey clubs were interviewed. Results show that the coaches highlight three reasons for early dropout; focus on competition, results and too much training in younger ages..

Studiens syfte Àr att undersöka om det finns ett sambandmellan sammansÀttningen av svenska börsnoterade bolagsersÀttningskommittéer och den ersÀttning som bolagetsverkstÀllande direktör erhÄller.De metoder vilka har tillÀmpats för att uppnÄ studiens syftehar varit tvÀrsnittsregression, OLS, t-test samtkontrollvariabler.Vi finner att det finns ett signifikant samband mellanmedelÄldern i ersÀttningskommittén och den ersÀttning sombetalas till VD i form av Total Pay och Noncontingent Pay.För övriga testade variabler finner vi inte nÄgot sambandmed de beroende variablerna..

Bakgrund: Enhanced recovery after surgery (ERAS) protokoll finns inom de flesta kirurgiska omr?dena men saknas till stor del inom hj?rtkirurgi, speciellt inom svensk sjukv?rd. Fler och fler kliniker implementerar ERAS-protokoll inom de olika kirurgiska specialiteterna. Postoperativt illam?ende och kr?kning (PONV) kan leda till on?digt lidande hos de patienter som drabbas.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Artificial sweeteners in beverage and their effecton hunger and energy intakeAuthor: Sofia Andersson and Sofia JakobssonSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2012BackgroundIn 2010 the total consumption of soft drinks in Sweden was estimated to 69 litres per person and17 % of the domestic production was estimated to consist of soft drinks sweetened with artificialsweeteners. The effects of artificial sweeteners on hunger is not yet fully understood. It isspeculated that they might increase hunger and hence increase energy intake.ObjectiveThe aim was to compile the evidence regarding the effects of an intake of a beverage sweetenedwith artificial sweeteners compared to sucrose on subsequent hunger and energy intake.Search strategyA systematic search for literature was performed in the databases PubMed and Scopus.Selection criteriaThe inclusion criteria were RCT, human studies, articles published in Swedish or English, studieson healthy adults and studies measuring hunger with a subjective scale or energy intake. Theexclusion criteria were studies who measured energy intake under other forms than standardisedor controlled, studies without a standardised dose of the beverage and articles needed to beordered against payment.Data collection and analysisFour articles were selected and examined according to a template developed by SBU. Theevidence for each outcome was weighed together and graded according to GRADE based on asummarised evidence form developed by the Sahlgrenska Academy.Main resultsAll four articles measured subjectively rated hunger.

Bakgrund: Bonussystem Àr nÄgot som började vÀxa fram under 1980-talet och Àr ett inte sÀllan förekommande debattÀmne. Inte minst i dagens situation med en stark recession och en finansiell kris om knuten. Flertalet artiklar har tagit upp Àmnet, dÀr man har ifrÄgasatt olika företags utdelning utav enorma rörliga ersÀttningar trots den svÄra tid vi nu befinner oss i. Företagen motiverar olika andledningar till varför de vÀljer att betala ut bonusar till sina vd:ar, som grundar sig pÄ olika typer av variabler.Syfte: Uppsatsens syfte Àr att undersöka vilken typ av variabler som visar starkast korrelation med storleken pÄ företagsledarnas bonusar, och att se om dessa kan tÀnkas pÄverka deras risktagande.Metod: Uppsatsen bygger pÄ en kvantitativ undersökning av sekundÀrdata som har inhÀmtats frÄn de utvalda företagens Ärsredovisningar. Undersökningen tar en deduktiv ansats, dÀr de valda teorierna appliceras pÄ de resultat som undersökningen visar.Resultat: De fem företagen som betalar ut högst total ersÀttning Àr ABB, Ericsson, AstraZeneca, Getinge och Scania.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.
