Hackelselängdens betydelse för tuggtid och foderkonsumtion hos mjölkkor :

Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis. Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.

Kapitalstrukturens inverkan på företags lönsamhet och värde : En empirisk studie över svenska börsnoterade fastighetsbolag

How capital structure influences corporate performance and value has been in the interest of researchers and scholars for more than half a century, but an answer is yet to be found. The main objective of the present paper is to contribute with data for this cause and hopefully help to clarify this mystery. The method that was used was by analyzing the impact of debt on profitability and market valuation through linear regression. The study examined 17 Swedish property companies listed on Nasdaq OMX Large Mid and Small Cap over a 6 year period (2007-2012). The authors found a slightly negative relationship between debt-to-equity and profitability measured by return on equity (ROE) as well as by return on assets (ROA).

Engagerade ungdomar : en hållbar energistrategi

The consumption and energy use in today's society contributes to the on-going climate change that creates a debt of life quality for future generations (www, DN, 2007, a). The resources that are used by humans exceed by far what is sustainable (www, Regeringen, 2007, a). The purpose of this paper is to examine how a message about energy conservation should be designed to reach youths. This will be attempted by showing their thoughts on energy and environmental issues and also what it would take for them to get more involved in these issues. The views of the youths are gained by a number of focus group-interviews, which where carried out in the fall of 2007, with kids in the ages 12 to 19. Apart from these interviews, interviews where also conducted with representatives from different youth organisations in Sweden, which gave their views on how to get a message across to kids.

Gymnasiebehörighet och sociala faktorer med linjär regression /  The Influence of Social Factors on School Performance using the Linear Regression Model.

I det här arbetet har linjär regression använts för att undersöka omolika sociala faktorer påverkar om elever får gymnasiebehörighet. Undersökningen gjordes med kommunvis aggregerad data och faktorerna somundersöktes var utländsk bakgrund, försörjningsstöd, utbildningsnivå, arbetslöshet, disponibel inkomst, lärartäthet, andel lärare med pedagogiskexamen och skolornas kostnad.Statistiskt signikanta resultat erhölls för utländsk bakgrund, försörjningsstöd, utbildningsnivå, disponibel inkomst och lärartäthet. Enligtundersökningen påverkar utländsk bakgrund och försörjningsstöd gymnasiebehörigheten negativt. Utbildningsnivå och disponibel inkomst påverkarden positivt. Lärartätheten påverkar gymnasiebehörigheten positivt omandelen lärare i svenska som andraspråk och modersmål inte överstiger10,4 %.Resultaten för resten av de undersökta faktorerna var inte statistisktsignikanta och därför kan inget sägas säkert om dem utifrån den härundersökningen.Observera att inga slutsatser kan dras på individnivå.

Förstudier av kommersiella fastigheter : En analys av arbetssätt ur ett projektledarperspektiv

This thesis is written at WSP management and investigates the practice of pre-project planning and feasibility studies at Swedish construction companies, through the study of the ongoing feasibility study of the mall Sturegallerian in Stockholm, and through interviews with experienced project managers in the construction industry. There is currently a big span in the way Swedish construction companies plan the pre-project phase and the aim of this thesis is to present a more generic and standardized way that helps minimize project risks and maximize efficiency and profit. The result is a generic model which can be used in pre-project planning. The model describes the phases in the preproject planning process and the activities that span these phases. Is also describes the categories of professions that need to participate in the preproject planning group and which activities that each profession executes. The other result is a list of factors that need to be considered for a well performed pre-project phase, as found during the interviews. Among others the thesis stresses the importance of involving the client as a key participant in the process.

Kvalitet på vägdata : inventering av skogsbilvägars standard samt jämförelser med lokal bedömning och SNVDB.

During 2006 SNVDB (the national road data base for forestry) is being introduced to Holmen Skog. This data base contains all information about Holmen Skogs road systems. The information will then be used in different kinds of optimisation models which only produce correct and reliable results if the input data are of the adequate quality. Today there are reasons to believe that road data is of various qualities. The forest roads are often in a bad condition and have to be improved before a planned harvest. The cost of maintenance and construction of new roads is a large part of the total harvesting cost.

Genus och etnicitet bland ungdomar och personal på boenden för ensamkommande asylsökande ungdomar : En kvalitativ studie om riktlinjer kontra praktik

Studies show that 10-15 percent of Sweden's population, 65 years or older are estimated to have depression or depression symptoms. The symptoms of depression among elderly people are less than symptoms of young people. This could cause that elderly people with depression are not always discovered. Studies show that elderly people who live in residential homes show more signs of depression than elderly people living at home. If elderly people live in a supporting environment, can it prevent that a depression developed.The prevention of depression among elderly people is a topic that is not discussed among previously research.

Omega System Kalibrering: Strål X-Separation mätning och kalibrering

Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.

Provinssnickarens poesi

I have studied and worked with various joints and interpreted twenty-six of them to small models. I then placed these into a template so that I could record the properties and their expressions.The protocol show what the joint looks like, and what its strengths and weaknesses are. Moreover, they are translated into a freer text, a poem, that describes what I think and feel about the joint.Based on the protocols, I have selected a number of joints which I then interpret into furniture. I have chosen to move forward in slightly different ways with different joints. Sometimes it is the expression of the joint that has given birth to a new idea, it may be the poem itself that led me on to a form, combinations of joints and that I found interesting, and so on.My interpretations are then further translated into new poems that describe what I see and what I feel when I assemble and disassemble each piece of furniture..

Analys av institutionell kapitalförvaltning: Stiftelserna som bildades ur de forna löntagarfonderna

This paper studies the research foundations created in 1994 from the former wage earners? funds out of a portfolio management point of view. Firstly it describes the seven largest foundations and their different portfolio management structures. Secondly it analyses the performance of these foundations measured as the intercept, Jensen?s a, in a linear regression of the excess returns of a portfolio versus a proxy for the market, as well as the Sharpe-ratio.

Demokrati, ett uppdrag för skolan : En implementeringssudie angående demokratiuppdraget i skolan

The current study sought to examine if post-produced semantic memory cues are a good aid for memory recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory recall. The results were discussed in regards to modern models describing semantic memory.

Inkludering en del av en klass? : Hur 12 pedagoger tänker kring inkludering och dess innebörder.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Uppfyller BIM förväntningarna som arbetsmetod för broprojekt?

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
