Norrländsk känsla för Japan
Sweden signed, in 1992, the Convention on Biological Diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board of Agriculture (SJV) in 1996, it appeared that there were around 780 cows and heifers of the SLB breed (SJV, 1997). SJV did in 2006 a plan for the development of livestock genet-ic resources and the number of cows of SLB was estimated at approximately 200. This meant that the SLB was in need of being conserved and SJV assumed it would be categorized as threatened.The primary objective of conservation of a breed is to reduce the loss of the original genetic variation (Lacy et al., 1995).
Rostfritt stål som ett alternativt material till koppar i tappvattenledningar för bostäder
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.
Sambandet mellan förändringar i fonders portföljsammansättning och prestation : Effekten av ett nytt aktivitetsmått
Tidigare forskning är inte enig om aktivt förvaltade fonder presterar bättre eller sämre än index. Då hänsyn inte tas till olika nivåer av aktivitet tycks de flesta studier visa att aktiv förvaltning är en förlustaffär för fondsparare. Vi introducerar ett nytt mått på aktivitet, aktivitetsgrad, som utgår från de åtgärder förvaltaren vidtar. Aktivitetsgraden definieras av mängden och storleken på förändringar i portföljsammansättningen som sker under ett kvartal. Vi undersöker aktivitetsgraden hos 22 svenska småbolagsfonder mellan 2008 och 2013 och finner att de flesta fonder har en låg aktivitetsgrad.
Självscanningssystemet : Dess för- och nackdelar
The purpose with our thesis is to understand and explain the advantages and disadvantages there is with the self scanning system. The advantages and disadvantages we will highlight from three different angels; the store management perspective, the staff perspective and the customer perspective. These three perspectives will together form an overall perspective over the advantages and disadvantages as the self scanning system has contributed with. Finally we will highlight the differences and resemblances we have found between the perspectives.Through a qualitative approach we have gathered data to our thesis. Furthermore we have based our theory chapter and our empirical chapter on the base of Grounded Theory.
Kall potatis i forskningens namn: Konstruktion av ett kompendium som stöder utveckling av processkunskap inom biologiundervisningen i gymnasieskolan
Inom ramen för examensarbetet konstruerades ett kompendium som ska förmedla
kunskap om den vetenskapliga processen genom integration av autentiska experiment i
skolan. Materialet ska hjälpa eleverna att konstruera sina egna experiment och samtidigt
bli medvetna om ?tänkandet bakom görandet?. Kompendiet riktar sig till elever i
gymnasieskolans biologiundervisning, och kan med fördel användas inom kursen
biologi breddning. Den experimentella metoden som används är blodsockermätningar
med eleven själv som mätsystem.
Implied Dividends and Equity Returns
This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.
Standardisering av snöröjningsplan : Instruktioner, råd och tips för snöröjning av tak med stora spännvidder
The Swedish winters 2009/10 and 2010/11 were rich in snow and many roofs collapsed, mainly largespan frames. Investigations were made and the amount of snow was not the primary cause, insteadthere were several other causes. One of these was that in some cases roofs were shoveled in anunfavorable manner which affected the load patterns negatively, so causing the roofs to collapse.Most people lack the knowledge of how shoveling will affect the roof. Had there been an increasedunderstanding regarding shoveling, some roofs could have been prevented from collapsing.Through both qualitative and quantitative research in the form of interviews and calculations thetheoretically best ways to shovel a selection of roof types is presented in the report. The roofstructures covered are 3-compartment, continuous and Gerberspliced metal roof decks.
Skadeanalys och omkonstruktion av HMS Belos A-ram
In order to rescue a distressed submarine crew, the Swedish Navy is able to use a deep submergence rescue vehicle, DSRV. This mini submarine ascends, docks to the downed submarine and picks up the whole crew. The submarine rescue ship HMS Belos has a special crane located in the aft of the ship to lift the surfaced DSRV aboard, which then docks on to the on board pressure chambers located below deck. During inspections the aforementioned crane has shown to have problems with cracks in the structure, most of them located in the bolted joint between the top part of the crane and the two leg parts. A simulation of the forces acting on the structure in heavy sea condition was conducted; these values were then used as input values in a Finite Element Method, FEM, analysis of the joint.
En kvantitativ studie avseende kriminalvårdares empati
Empati har länge ansetts vara en god egenskap hos en medmänniska. Det definierats enligt Davis, som individers affektiva och fysiologiska reaktioner avseende någon annans fysiska och psykiska tillstånd. Tidigare forskning har visat att det finns skillnader avseende empati hos individer beroende på olika faktorer. Huvudsyftet med studien var att se om kön, ålder, arbetsplats, antal år inom yrket samt föräldraskap påverkade kriminalvårdares empati. Deltagarna var kriminalvårdare (N = 90) som arbetade på en anstalt och ett häkte.
Människovana grävlingar som testdjur för grythundar. En studie om hur grävlingars beteende och fysiologi påverkas av hundars aggressivitet
In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).
Kapitalstruktur inom Svenska industriföretag : - en studie av Modigliani & Millers teorem
This paper?s objective is to investigate whether Modigliani and Miller (MM) I & II proposition from 1958 with regard to capital structure, is still valid among public Swedish firms.We have chosen the 63 firms on the Stockholm Stock Exchange (OMX) that Affärsvärlden magazine?s general index (AFGX) has categorized as industrial firms. We based this selection on the assumption that these firms are relatively capital intense and have a clear focus on production and, therefore, mainly uses capital structure as a mean to finance their production and not as a means in itself.To be able to fully evaluate these firms we have calculated the current key ratios based each firm?s annual report. To make the figures comparable across the entire population we adjusted them to each firm?s turnover.The results we have reached concur with MM?s proposition I regarding capital structures independence of the firm value.
Utmattning av vägbroar i armerad betong enligt eurokoder
Since 1 January 2010 it is a requirement to use the European standards, Eurocodes, in Sweden when constructing bridges. One chapter that has caused an extra amount of problems for the engineers is the one about fatigue analysis, which resulted in us doing this thesis.To do this we had to read all of the Eurocodes that direct, or indirect deals with fatigue and calculating of such. We have read the background documents for the Eurocodes and master?s thesis in the subject. We also studied the calculations of bridges constructed by different construction firms.We have chosen to limit the thesis to discuss only road bridges made of concrete due to the lack of method for verification of concrete in the national appendix.
Upplevelser i samband med en obotlig cancersjukdom : En litteraturstudie baserad på vetenskapliga artiklar samt självbiografier
BACKGROUND: One of the nurse?s areas of responsibility is to relieve suffering. Research has shown that nurses give an indication of an emotional load in the interaction with dying patients. This means that patients need of relieved suffering gets disregarded because of nurse?s fear of the unknown.
?Du kan göra skillnad i människors liv utan att ha en aning om det? : En kvalitativ studie om några socialsekreterares syn på suicidalitet
During 2010, 1446 people committed suicide in Sweden. Research shows that groups that are less favored in society have an increased risk of suicide. Social services often encounter groups of people that have a high risk of suicide, for instance welfare recipients or substance abusers. The purpose of this study was to shed light on how social workers talk about suicide and how this might affect interactions with suicidal clients. The study is based on qualitative interviews with five social workers in Stockholm.
Nu ska vi jobba med serier : didaktiska reflektioner om serier och seriemassighet i bildundervisning.
Denna undersökningen är ett försök att se hur mycket av ämnesundervisning, kursplan och kursmål som kan rymmas inom serietecknande som (undervisnings) metod. Genom att knyta an till elevers egen kulturkonsumtion hoppas jag kunna knyta an ny kunskap till det eleven redan är bekant med. Serier blir då här som en brygga mellan det de redan vet och det de ska lära. Arbetet genomförs genom undervisningsförsök som vetenskaplig metod och genom diskursanalys av seriemediet. Jag tycker mig se genom detta arbete att man ur det seriemassiga, serierna i sig och serierelaterat innehåll i allmänhet, kan skapa en pedagogisk metod för bildämnet.Detta är ett s.k.
