Kan mjölkkors utnyttjande av vallprotein bli bättre? : utfodringsstrategier och konserveringsmetoder

The purpose with this literature study was to investigate the possibilities for improvement of forage protein in dairy cows with focus on feeding strategies and conservation of forage protein. The utilization of forage protein in dairy cows is often not that efficient as it could be. The feed crude protein consists of both true proteins and non protein nitrogen. The digestion of proteins in the rumen depends on the protein Degradation rate and the ability of the microbes to synthesize microbial protein. The microbes need a balance between carbohydrates that provide them with energy and proteins that are degradable in the rumen.

Barnkullar och arbetslöshet - Stora barnkullar och möjligheter på arbetsmarknaden

Youth unemployment in Europe is a big problem today. The number of unemployed young people has risen past decades, from 10 % in1980 to over 20 % 2010. The purpose with this thesis is to deal with big cohorts and unemployment rate for young people 20-24 years old in Sweden. I have a look at three different generations, people born:1963-1967 and start working 19871968-1972 and start working 19941988 and start working 2008-2012Did these people from a baby boom face any specific difficulties when entering the labor market 20-24 years later? I have used Easterlin theory in my work and lokked at statistics from SCB (Statsitiska centralbyrån) in Sweden.

Flygplansavisningens miljöpåverkan vid svenska flygplatser

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

Aktiekursförändringar och sökfrekvens på internet

The purpose of this Bachelor thesis is to analyze if there is a correlation between stock prices and the amount of searches of the companies names on Google. The theories used in the study were Capital Asset Pricing Model (CAPM) and Efficient Market Hypothesis (EMH). Regressions analysis is used as the statistical method to see if there is a significant correlation between the stock prices and the amout of searches of the company name on Google. The data used were the rate of return of three companies (ABB, Oriflame and Sandvik) on the Nasdaq OMX Nordic stock market, the rate of return of the Nasdaq OMX Nordic stock market index (OMX Stockholm_PI) and the Google search frequency from Google Trends on each company. The result showed no significance and the conclusion of the thesis is that there is no significant correlation between the three studied companies and their search frequency on the search engine Google..

Feromoninnehållande substansers inverkan på hjärtfrekvensen hos tjur :

During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

Carry Trade : Vad säger teorin och hur ter sig verkligheten?

I nära tio år har främst amerikanska placerare utnyttjat strategin carry trade för att skapa positiva avkastningar. Strategin innebär att lån tas på en marknad med låga räntor för att sedan placeras på en annan marknad med högre räntor. Det är främst de japanska och amerikanska räntemarknaderna som har använts.Syftet med uppsatsen är att utreda om det går att få en positiv avkastning vid carry trade-affärer. Vi kommer även att belysa vilka risker som uppstår vid dessa investeringar, samt undersöka vad som kan göras för att minimera de risker som uppstår. Genom att studera andra länder med betydande räntedifferenser vill vi även utreda om denna strategi går att tillämpa på andra ränte- och valutamarknader än Japan och USA.För att uppfylla syftet har en kvantitativ studie genomförts baserad på sekundärdata, där vi skapat olika fiktiva affärer över tre tidsperioder för att kunna räkna ut och jämföra avkastningar.

Transferfunktionsmodeller modellering och prognoser av Sjötransportindex

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

Besparingsmodell för produktivitetshöjande arbete inom skärande bearbetningsteknik

The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.

Riskpremie i UIP - möjlighet till cross-currency arbitrage? - en jämförande studie av ränta och växelkurs mellan Storbritannien, Tyskland och Sverige.

The thesis explores the Uncovered Interest rate Parity (UIP) and the possibility of cross-currency arbitrage between England, Germany and Sweden. The data is gathered between May 1999 and December 2005 on a monthly basis and is compared using simple regression analysis. The aim is to find out whether UIP holds and, if it does not, a risk premium exists that makes it possible to make arbitrage gains on moving capital between England, Germany and Sweden. It is discovered that UIP does not hold and that cross-currency arbitrage possibilities exist. In the end a an attempt is made to practically show how the arbitrage possibility could be used for a real investor to make risk free gains from the Foreign Exchange market..

Mer än bara pengar? - En kvantitativ undersökning om huruvida U-länders statskapacitet påverkas av multinationella företag

This thesis takes as its starting-point the different stands on the ever ongoing growth of multinational corporations (MNCs) and its consequences. Two opposing branches of theories, arguing that the establishment of MNCs in developing countries is good respectively bad for these countries, are tested for the aspect of state capacity. A quantitative method is then used to test if there exists such a relationship at all and if so, which of the two notions that are right.The presence of MNCs is measured as FDI of GDP while state capacity is defined as a combined index for three of ICRG's Political risk indicators. The two variables are analysed, mainly by cross tabulation, using an extensive dataset of 130 developing countries measured for a period of 20 years.The outcome is though ambiguous: No solid correlation can be found, but countries with a higher rate of FDI of GDP tend to have a slight worse rate of state capacity throughout the analysis. Thus the result points in favour of the notion that MNCs are bad for developing countries? state capacity.

Biogasproduktion genom tvåstegsrötning av drankvatten

During the 19-century a global warming has been observed, which includes increases in global air and ocean temperatures, widespread melting of ice and snow, and rising global sea level. There is a clear connection between emissions of greenhouse gases caused by the human and the increase in temperature. Climatic changes caused by global warming can be stopped trough decreased emission of fossil fuels, for example by an increased use of biogas. Biogas is a renewable energy source which is produced through anaerobic (oxygen free) digestion of organic material. The gas is a mixture of methane (CH4) and carbon dioxide (CO2) and can be among others used as fuel in vehicles.

Dysartribedömning på svenska av typiska talare över 65 år med finska som förstaspråk

The aim of this paper was to investigate how 40 typical speakerswith Finnish accent, aged 65-84 years, performed in speech assessmentthrough Dysartribedömningen, a Swedish dysarthria assessment instrument.Their results were compared with results of a matched Swedish nativespeaking reference group. Both groups were assessed in areas offunction/structure, prosody/intelligibility and through a survey oncommunication. Results indicated that the performances of the Finnishparticipant group were estimated as more deviant than the Swedish,considering all areas. The Finnish participants were deviant in articulationand they had a significantly lower speech rate in reading. They also hadsignificantly lower scores in intelligibility compared to the reference group.The results of the survey of communication showed that the Finnishparticipants estimated their levels of activity and participation to besignificantly more limited compared to the reference group.

Annonsplacering : Hur placeringen av annonser i artiklar kan optimeras för högre Click Through Rate

The web as an arena for news reporting and information sharing to consumers has grown for many years in the expense of the traditional newspapers. The revenue stream has however not followed the same transformation which has led to a remarkably lower profit when news and articles are distributed through the web. Banner advertising is a method that is commonly used by online magazines to generate profit where advertisers pay to expose their message. One method to measure banner ads effectivity, and indirectly, what the advertiser would pay, is through Click-Through Rate (CTR), how many clicks a banner ad receives in relation to the amount of banner views. One of the variables that play an important role in the banner ad effectivity is the placement of the banner ad.

Bottensubstratets inverkan på föryngring av Flodpärlmussla

The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.
