The aim with this report was to exam and surveys the internal logistics of Proton Finishing?s production. The basic data should give the company suggestions of more efficient and improved internal logistics. We will also give from our perspective suggestions of improvement, which the company will be able to evaluate.To evaluate these problems we used different kinds of methods. A frequency study was made on the internal forklift.

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.

Funding is essential for companies to function. All companies must relate to the funding issue, whether they are working with it in an active manner or not. Funding can be done in two ways, either through equity or debt and the ratio between these are called capital structure. Already in 1958 Modigliani and Miller concluded that a company?s capital structure does not change the value of the company, thus the company?s debt in relation to equity is irrelevant.

In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.

The high feeding value of red clover makes it into an important species in Swedish agriculture. There are three different maturity types grown in Sweden, early, medium late and late. The time for heading, regrowth and winter hardiness is affected by the maturity type, but there can also be other factors that are affected by the maturity type, for instance fiber content. In a greenhouse experiment three red clover varieties of different maturity types were compared; early Titus, middle late SW Nancy and late SW Torun. The features compared were fiber content and differences in development rates.

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

This thesis aims to investigate if peer-groups based on industry classification perform as well as, or better than, peer-groups based on other measures that represent factors affecting the price-to-earnings multiple. In contrast with previous empirical studies, a solid theoretical approach is used in defining which factors, according to valuation theory, affect the P/E-ratio. The factors identified as explanatory are accounting measures, risk and growth. Furthermore, we have recognized several measures that represent these factors. These measures are tested for accuracy of prediction in terms of the P/E-ratio for peer-groups based on these measures relative to an industry classified peer-group.

Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate deciduous forest.

I denna uppsats undersöker författaren kapitalstrukturens i de svenska oljebolagen. Syftet med uppsatsen är att undersöka är hur kapitalstrukturen utvecklats under perioden 2001 till 2009 i de svenska oljebolagen, vilka metoder för kapitalanskaffning som använts under perioden, om bolagsrisken påverkar kapitalstrukturen, samt hur oljebolagen förhåller sig till Peak Oil och alternativabränslen och energikällor.Följande slutsatser kan dras från undersökningen: Mellan 2001 till 2009 har det egna kapitalet i bolagen legat i en stigandetrend, medan de långfristiga lånen varit i en nedåtgående trend. Bolagen har finansierat sin verksamhet med minst 50% eget kapital under perioden.? Bolagen har mest använt sig av nyemissioner när de tagit in nytt kapital, följt av olika former av lån och slutligen konvertibellån. En statistisk undersökning har visat att risk påverkar eget kapital. När risken ökar, så ökar det egna kapitalet.

Utifrån en historisk jämförelse av de tre äldsta svenska ETFerna undersöker vi huruvida svensknoterade ETFer är en bättre placeringsstrategi än aktivt förvaltade Sverigefonder. Studien genomförs med de fyra utvärderingsmåtten Sharpe Ratio, Treynor Ratio, Jensen?s alfa samt Information Ratio för att se om ETFer ger högre riskjusterad avkastning än jämförbara aktivt förvaltade Sverigefonder. De tre ETFerna, XACT OMXS30, XACT OMXSB och XACT OMXSBULL jämförs mot samtliga aktivt förvaltade Sverigefonder som har som strategi att investera i stora bolag listade på Stockholmsbörsen. Samtliga utvärderingsmått ger tvetydiga resultat men två av de undersökta ETFerna visar sig ha genererat högre riskjusterad överavkastning än de jämförda fonderna.

One can find it problematic to communicate in today?s information society and therefore has the importance of distributing information the right way grown. Managers possess the authority to control what information is to be distributed how and that has created a big need for managers to learn how to communicate. This study was conducted in hope of enlightening the phenomenon male and female management communication. We chose to do a case study on two managers on Solna Stad in Stockholm. One male and one female.

During sleep the majority of the body?s production of anabolic hormones is produced and sleep is a general anabolic state of being. It has been to our recognition that a powernap is 4-6 times more effective when it comes to sleep intensity than the last 1-2 hours of a traditional eight hour sleep. With this in mind, and that elite athletes worldwide often sleeps in between their training sessions. This study has tried to prove a hypothesis which comes from the assumption that you can recover and perform better during times with intensive periods with better distribution of your sleep.We have in this study let three test subjects take part of a six week long program with two different training periods for legs.

Ultrasound is a diagnostic aid often overlooked by the veterinary practicioner who works with farm-animals. However, it?s use increases, particulary for breeders where ultrasound has long been used to evaluate ovaries and to diagnose pregnancy or disturbances in reproduction. There is much knowledge in how to examine ovaries and uterus by transrectal ultrasound, but when it comes to doing ultrasound of other organs in the abdomen the knowledge is more limited. Cows are very large animals, so it is not possible to examine everything inside the abdomen with ultrasound, simply because the ultrasound beam has a limited penetration. There is also lots of gas inside the gastro-intestinal tract of a cow, mainly in the large intestine and the rumen, and that makes it impossible to examine the organs behind the gas since the ultrasound waves are reflected when reaching the soft tissue-gas interface.

Tidigare studier har visat en korrelation mellan muskelgrupper, särskilt gällande styrka mellan olika muskelgrupper i samma extremitet. Syftet med den här studien var att se om maximal isokinetisk muskelstyrka i låret korrelerar med maximal isometrisk handgreppstyrka hos friska individer >60 år. Exklusionskriterier var muskuloskeletala besvär, hjärt? kärlsjukdom, KOL, RA, Gonartros eller pågående infektion. Isokinetisk benstyrka mättes på 25 försökspersoner >60 år i Biodex System 3 och isometrisk handgreppstyrka mättes med Grip-D.

Denna uppsats kretsar kring två företags återhämtningsarbete vid uppkomsten av respektive skandal. Vidare skapas en djupare förståelse för teorin Service Recovery's betydelse och användning i praktiken. De två fallen där skandaler inträffat är grundade dels i ICA:s köttfärsskandal och dels i IKEA:s fjäderplockningsskandal. Uppsatsen har en deduktiv ansats vilket innebär att uppsatsen utgår från befintliga teorier som sedan testas med det insamlade empiriska materialet. Den teoretiska referensramen innefattar främst Grönroos teorier kring Service Recovery och kompletteras med teorier så som Service Recovery Paradox, kundförväntningar, sociala medier och immateriell påverkan.Uppsatsens forskningsfrågor besvaras främst med hjälp av en fallstudie med två företagsanalyser samt med en enkätundersökning. Studien är av både kvalitativ och kvantitativ karaktär där kvalitativ data samlats in via en e-mail intervju med Ylva Magnusson vid IKEA, och kvantitativt via en enkätundersökning.Uppsatsen har resulterat i kännedom om hur de två företagen arbetat med att återfå kundförtroende.
