Tidig elit? : En kvantitativ studie om eleverna på Sveriges elitinnebandygymnasier
Syfte och frågeställningar:Studiens huvudsakliga syfte var att undersöka vilka elever som går på Sveriges elitinnebandygymnasier efter reformen av den gymnasiala idrottsutbildningen.Ytterligare ett syfte var att urskilja påverkansfaktorer i utvecklingsprocessen som innebandyspelare.- Hur ser förekomsten av relative age effect ut på elevpopulationen?- Hur upplever eleverna sina förväntningar och egna förmåga i sitt innebandyutövande?- Hur ser elevernas idrottsbakgrund ut?Metod: Enkätundersökning har använts som metod i denna studie. Totalt har 132 elever på Sveriges elitinnebandygymnasier besvarat enkäten. Könsfördelningen var 46 flickor och 86 pojkar. Enkäten bestod av både öppna och slutna frågor där eleverna fick besvara frågor som rörde deras idrottande idag samt idrottsbakgrund.Resultat: Elevernas födelsefördelning var spridd sett till hela populationen.
Dygnsvariation av metanemission från en anlagd våtmark
The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. The wetland (in Nykvarn outside of Linköping, Sweden) takes care of wastewater to reduce the nitrogen loads. Measurements were carried out at three different occasions in the summer of 1998 on two sites in the wetland. One site was close to the inflow, inhabited by Lemnaceae, and another site was located further downstream inhabited by the emergent macrophyte Typha latifolia.
Fuktproblem i chilenska småhus
Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.
Harmonisering av redovisningsstandarder
Earlier models that measured de facto harmonization of international accounting mainly used indices and other related statistical models. Those approaches do not account for the relative importance of individual balance sheet items or expense items being harmonized. This paper therefore proposes a different approach using Runsten?s (1998) permanent measurement bias model. That way it is possible to quantify the harmonization process by accounting for differences among companies.
Aktieåterköp och undervärdering: : En empirisk studie av signalling-teorin
This paper tests the information signalling hypothesis on a sample of firms making open market stock repurchases. Using an earnings-based valuation model, we find that a majority of repurchasing firms are undervalued relative to their economic value. This result is consistent with previous academic studies, which claim that undervaluation is the prevalent factor explaining the observed abnormal return following the announcement of a repurchase program. We do not, however, find any evidence that the repurchase is consciously made by management to provide the market with new information. .
Kv. Tvättstugan, ett flerbostadshus med massiv trästomme : Ett examensarbete om akustik- och brandkrav samt en jämförelse av energi- och fuktaspekter
Title: Kvarteret Tvättstugan, an apartment building with massive wood construction. A thesis about acoustic and fire requirements and a comparison of energy and moisture aspects. Earlier restrictions in the Swedish legislation have resulted that only a small percentage of the apartment buildings that have been built are designed with a massive wood construction. It has been allowed to build unrestricted with wood since 1994 as long as the function of requirements are fulfilled. This change in the rules together with the great environmental benefits of wood has led to that more companies choose to build apartment buildings with wood. One of these companies is Folkhem Production AB.
Systematiskt arbete för att hantera osäkerheter vid mätning : vid Q-Med AB i Uppsala
This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.
Planteringsförbandets betydelse för kvalitetsegenskaper i Contortatall (Pinus contorta var. latifolia)
In Sweden, large scale planting of Lodgepole pine (Pinus contorta var. latifolia) started in the beginning of the 1970?s. At first, the aim was production of pulpwood, but later, also production of timber became considered realistic. Today, Sweden has more than 520 000 ha of Lodgepole pine.
Förändrad attityd - nya vanor! : En kvalitativ kohortstudie om motionsvanor och medvetenhet hos barn som medverkat i en intervention mot övervikt och fetma
AimThe aim of this study is to examine the long term effects of e12 and how they have influenced the lifestyle and perceived awareness about nutrition and exercise in relation to factors from Social Cognitive Theory (SCT) that e12 took in consideration. The questions asked were; How has e12 affected the attitudes, skills, self-efficacy and knowledge relative to exercise? How has e12 influenced the individual?s habits of exercise? How has e12 affected the perceived awareness regarding the impact of nutrition and exercise on the body weight?MethodThe study is pursued by a qualitative method using semi structured interviews on six individuals between the ages of 16-18 years old that completed the project 4-5 years ago. A questionnaire regarding nutrition and exercise habits was also used as part of the study. All individuals from the year of interest were first contacted by the senior physician connected to the project.
Entrén vid Universitetssjukhuset i Lund : hälsosjukhuset med frånvaro av trivsamhet
Scientific research shows that humans regain their strength when they are spending
time in nature. Ulrich, Kaplan & Kaplan, among others, has shown in their research
that nature can reduce stress and decrease the after effects of stress. Lund University
Hospital, USiL, is a big working place and has a large number of patients. To be a
patient often means that you lose control of your daily life which could cause stress.
For the personnel high workload can be a stress factor.

Reglerstrategi för fria ventiler : ? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar
As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.
Vattentäta och ?andande? textilier
Rapporten innefattar en jämförande studie mellan olika typer av membran och beläggningar.Främst sker en jämförelse mellan materialens förmåga att andas. Vattentäthet testas på nyamaterial och efter olika sorters nötning så som martindale, flexing och tvätt för att få en ökadförståelse för materialen. Verktyget som används i studien för att mätaånggenomsläppligheten är hudmodellen. Resultatet presenteras med ett Ret-värde vilket är enförkortning på Evaporative resistance of a textile. Metoden används för att på ett bra sättsimulera hur huden svettas.Projektet har utförts på Swerea IVF som är ett forskningsinstitut beläget i Mölndal.Hudmodellen är en av de senaste stora investeringarna på Swereas textil och plast avdelning.Resultatet av studien visar att laminat andas bättre än beläggningar, dock har bärarmaterialetstor inverkan på resultaten.
Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity
Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.
E-BUSINESS, WHAT IS IT GOOD FOR: AN EXPLANATORY STUDY OF FIVE COMPANIES? E-BUSINESS SOLUTIONS
The notion of firms interacting with technology is not new; these types of systems were already in place in the mid eighties. E-business users worked with connections between their inbound logistics and procurement systems, and suppliers? order-entry systems. When these connections were described for the first time the vertical links between two, or more, value chains in a value system received more attention in firm strategy. The design of the linkages in the value system was said to be a product of the need for coordination and relative bargaining power.
