The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

Detta examensarbete syftar till att exemplifiera vilka informationsparametrar som är nödvändiga för att Building Information Management på ett bättre sätt ska kunna implementeras i produktionsfasen. För att uppnå detta mål har vi analyserat utvecklingen och nyttjandet av Building Information Management genom tre olika datainsamlingsmetoder; litteraturstudie, observationer och intervjuer.  I detta examensarbete har vi fördjupat oss i för- och nackdelar samt hur Skanska Sverige AB kan tillämpa Building Information Management som hjälpmedel i arbetsberedningar. Denna fördjupning har lett till att vi kan analysera vilka produktionsanpassade informationsparametrar som en produktionsledare behöver i sin tjänsteroll för att dra nytta av Building Information Management.Vi anser att användandet av en BIM-modell kompletterar produktionsledarens ledaregenskaper, vilket gör det lättare för denne att nå fram med informationen till yrkesarbetarna, då visualiseringen underlättar förståelsen inför aktiviteten. I denna rapport kan läsaren ta del av de slutsatser vi kommit fram till..

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

Intresset och möjligheterna för att exponera sitt kapital mot fastigheter har funnits länge men ökat under de senaste årtiondena. Historiskt sett har bara direkta investeringar skapat denna exponering men idag finns andra alternativ så som fastighetsfonder och börsnoterade fastighetsbolag. På Stockholmsbörsen finns det idag 18 fastighetsbolag som har haft en varierande effektiv avkastning. Då flertalet av dessa bolag profilerar sig på ett liknande sätt kan det uppstå svårigheter att verkligen förstå vad som skiljer bolagen åt och förstå vilken risk bolagen utsätter sig för.I kombination med en viss strategi följer en riskprofil som kan vara mer eller mindre attraktiv för en investerare. För att urskilja mönster måste en analys ske på nyckeltalsnivå och det går inte att enbart rekommendera ett bolag utifrån en viss strategisk inriktning på grund av att nyckeltalen kontinuerligt förändras.Att investera i ett bolag med god direktavkastning, hög belåning och en betydande substansrabatt har historiskt visat sig vara lönsamt.

The purpose of this paper is to examine and analyze past development of mutual funds in large and small mutual fund companies and see if there are any differences between these two segments. Limitations on the number of funds have been made by choosing Nordic mutual fund companies that invest in emerging markets over an 11-year period. The study is made on 66 mutual funds managed by 13 mutual fund companies in which the segment of small fund companies includes seven fund companies with assets under management less than 100 billion SEK and the segment of large mutual fund companies includes six fund companies with assets under management more than 400 billion SEK. In the comparison of the segments the Sharpe ratio has been used to calculate the risk-adjusted return. The study shows small differences of the risk-adjusted return between the segments.

Purpose: Aims of this paper is to evaluate a comparative study between China and Russia funds in respect of the risks and returns. We also want to examine what has affected the funds in their respective domestic stock market.                                                            Method: The study is based on qualitative methodology to complement the quantitative survey by first gathering of secondary data from Morningstar, and fund manager´s stories on fund and banking companies' websites.  Primary data is conducted by the interview with fund manager. The sample consists of all land funds for China and Russia has found more than 10 years on the stock market.Results and Conclusion: The survey shows that China funds will generate better in decline than Russia Funds in both return and risk-adjusted Sharpe ratio. Because the China funds had better risk diversification and its holdings spread across different industry area while Russia funds is more directed towards oil and gas industry.

Renewable energy and the charging of electrical vehicles will increase in the future. Therefore the risk of outages is also increasing, partly because renewable energy is intermittent and the production amount can change fast. Charging electrical vehicles is often demanding high effect in short time, which could make faults occur. It takes more advanced technology to short the outage time. Today Övik Energi has high reliability in the power grid, but in order to maintain the reliability, it is time to prevent problems that can occur in the future. This thesis has presented a suggestion for the placement of fault detectors Protrol IPS2, in which a total of four detectors is proposed.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Titel: Country of Origin som marknadsföringsinstrument- Om betydelsen av ursprungsland vid marknadsföring i ett internationellt perspektiv Problem: Vilken betydelse har ursprungsland (COO) för konsumentens köppreferenser? Går det att upptäcka skillnader i COO-begreppets betydelse för produkter med hög respektive låg upplevd risk? Syfte: Att kartlägga och förstå fenomenet ursprungsland/Country of Origin vid marknadsföring i ett internationellt perspektiv Metod: Genomgång och översikt av för kunskapsområdet relevant aktuell litteratur. Kvantitativ undersökning av betydelsen av COO för svenska konsumenters köppreferenser vid hög respektive låg upplevd risk. Slutsatser: COO är en av flera faktorer som medverkar till att påverka konsumentens köpbeslut. Betydelsen av COO som determinant i köpbeslutsprocessen ska inte överskattas, men går heller inte att avfärda.

Bakgrundsbeskrivning: Traditionellt har risk betraktats som något negativt ocholika typer av risker har hanterats av olika funktioner. Sedan ett antal år har IntegratedRisk Management (IRM) utvecklats som koncept för riskhantering. IRM innebärsamordning och integration av riskhanteringsarbetet. Problemställning: I vissa länder har lagstiftning tvingat företag att implementerasystem som IRM, men det råder fortfarande viss oklarhet i vilka motiven ocheffekterna är. Vi frågar oss därför vilka anledningar det finns att använda IRM? Vad ärmålsättningen och motiven? Vilket värde (effekter) skapar det egentligen för företaget?Vidare saknas det studier i vad IRM innebär i praktiken, särskilt erfarenheter frånnordiska företag.

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

Syftet med uppsatsen är att undersöka hur svenska pensionsfonder presterat under perioden 2005-01-01 till 2009-12-07. Detta vill vi undersöka då det sker stora förflyttningar av pensionskapital i stundande tid inom det svenska pensionssystemet. Undersökningen innehåller ett urval på 25 svenska pensionsfonder hos sju av de stora svenska pensionsförvaltarna. Fyra fondtyper har använts i undersökningen: En aktiefond, en blandfond och två olika räntefonder. Utifrån historisk data har vi tagit fram avkastning och risk för aktuell tidsperiod hos fonderna.

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Background: The global responsibility for multinational companies is a current matter of subject. Now when the world increasingly is getting globalized, economic growth is created, which brings a bigger demand of responsibility on companies. The leading companies from every industry is often becoming the frame for how the production process works and is therefore exposed to outer pressure which, for example, is coming from consumers and the media. Since consumers at present are more aware of what they are buying and where it comes from, it is important that the companies take social responsibility. We have therefore studied three big companies within the clothing industry to see in witch way they are taking their social responsibility.Purpose: Our purpose was to explore how companies within the clothing industry describe their work with Corporate Social Responsibility, code of conducts and where the incentive behind this work is coming from.Method: We have, through a qualitative study, examined how three large companies work with Corporate Social Responsibility.
