New energy resources that can replace petroleum diesel are needed and biodiesel may be an excellent substitute. During storage and use, biodiesel can oxidize and form peroxides, leading to degradation of the fuel. It is therefore important to determine the peroxide content of the fuel. In this thesis the triphenylphosphine method, which involves GC-MS analysis has been compared to the standard iodometric method which involves titration with sodium thiosulfate. Working standards were made to see how well the iodometric method worked and also in order to make a calibration curve in GC-MS.

Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.

AbstractTitle: To Market a Company with the Help of Nationality ? A study in how marketing and branding works and is being perceived when it focuses on nationalityAuthor: Frida HanssonSubject: Media and Communication Studies CPeriod: Fall semester 2010Length: 38 pagesTutor: Else NygrenAim: Companies and various corporations are always on the hunt for the next big thing in marketing. One idea to market themselves and give them a chance to separate themselves from the cluster of companies aspiring to take your costumers away could be to market themselves with nationality. To investigate why and how some company?s chose to market themselves with nationality, and also study how this kind of marketing is being perceived by customers and non ?costumers.

AbstractThe purpose of this bachelor thesis is to describe the use of artificial insemination (AI) in sheep and discuss the possibilities for AI in Sweden. Male and female fertility, heat detection, semen handling and insemination techniques in sheep are described. Advantages and disadvantages of AI are discussed. In order to achieve genetic progress it is important with well planned and implemented breeding programs. The Swedish Sheep Recording Scheme and computer software from Elitlamm are the basis for sheep breeding in Sweden.

In most countries, the dairy industry focuses on the volume of milk produced instead of its composition. This results in a high content of water and a lower proportion of fat and protein. A high proportion of water is not desirable when processing the milk into various dairy products like cheese, cream and milk powder. High water content also increases the costs for transport and storage, and also an unnecessary, albeit marginal, strains on the world?s water reservoir.

The main purpose of this thesis has been to identify and discuss problems connected with the preservation of newspapers in Sweden. Another purpose was to see if the preservation of newspapers has been influenced by the fact that preservation studies in general concerns printed monographs and digital materials. This qualitative study is partly based upon interviews with four librarians experienced in working with newspapers and preservation. The thesis deals with cultural heritage in general and on a more specific level with newspapers where the following questions are dealt with: Why preserve? Who preserves? How to preserve? and What is preserved? Strategies used for preserving newspapers such as paper, microfilming and digitization are described as well as legal deposit, the Swedish microfilming programme and TIDEN, a digitization project of newspapers.

Research concerning movement patterns of wild animals has been advancing since GPS technology arrived. But studying the snow leopard (Panthera uncia) is still difficult because of the harsh territory it inhabits in Central Asia. This study took place in south Gobi, Mongolia, and aimed to estimate the time spent at kills and the maximum distance away from kills between visits. Snow leopards were monitored with GPS collars that took a location every five or seven hours. Potential kill sites were established by identifying clusters of GPS-locations in ArcGIS and visited in the field for confirmation.

This study was conducted to test the hypotheses that a forest managed by selective cutting can store more carbon than a forest managed by clearcutting. The study was carried out as a meta-analysis. The data that was found was analyzed by performing t-tests on the proportional effect that the two silvicultural methods had on the driving factors of CO2-efflux and carbon stores in coniferous boreal forest. In all areas tested, an effect in favor of selective cutting was found, but not all of them significant however. The soil respiration following selective cutting was significantly lower than that of clearcutting, and the primary production of a clearcut area cannot according to reason exceed that of an area post-selective cutting.

The Swedish field of digital X-ray imaging has since several years relied heavily on distributed information systems and digital storage containers. To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback?the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

It is of increasing importance to in the most effective possible way, manage and control all the transactions of raw materials, products and information that are exchanged between an organization and all its operators. These flows and the need for strategy and managing the processes of planning, implementing and control of the supply chain, has given name to the concept supply chain management. Supply chain management involves all movement and storage of raw material, and all the processes that is needed to manufacture a product from origin to consumption. Globalization, technology and increasing time and quality-based competition are all driving forces behind the concept and reasons for an increasing interest in supply chain management.The purpose of this essay is to by using a qualitative case study examine which decisive success factors that can be identified for effective supply chain management. We have compiled different theories on the subject to use for analyzing a case study Li & Fung, who is a successful supply chain management company.

Omställningen till ett mer hållbart samhälle spelar en betydande roll för att uppnå deEuropeiska mål och klimatavtalen, 20/20/20-målen. Ett av målen anger att andelen förnybarenergi ska öka vilket ställer högre krav på elnätets kvalitét. Framtidens elnät måste blimodernare, att det genom utvecklad styrning och övervakning kan balansera ökadeeffektvariationer och därmed erhålla en ökad stabilitet, så att god samverkan mellan förnybarelproduktion och elanvändning uppnås. Redan i dagsläget finns tekniska lösningar som gördet möjligt att konstruera ett sådant modernt elnät.Projektgruppens uppdragsgivare var Ystad Energi AB som ville undersöka möjligheten attansluta ett batterilager i samband med landanslutningen i Ystad hamn.När färjorna vid kaj ansluts till det fasta elnätet kan effektbehovet i Ystads lokala elnät öka iden utsträckningen att abonnerad effekt på överliggande elnät överskrids. I dagsläget är detinte möjligt att uppgradera till ett högre effektabonnemang eftersom transformatornsbegränsade maxeffekt som förser Ystad med elenergi redan är uppnådd.För att undersöka möjligheterna till ett batterilager, har dels Ystads effektbehov ochlandanslutningens tillkommande effektbehov analyserats.

The aim of this study is to find out whether there is any difference to be found in the attention ability before and after physical activity. The method used in this study was made of an experimental design. The participants were chosen through a cluster sampling and thereafter divided into a control group and an experimental group. A total of 64 pupils from upper secondary school participated in the study, 25 of them in the experimental group and 39 of them in the control group. Since the measure was repeated, both in respect of time and the comparison between the groups, a mixed design was used.

Within SM there are four sub-departments working with activities such as planning, purchasing, receiving inspection, storage and distribution.

Library architecture today is a complicated history. Public libraries are no longer merely a place for book storage, but also a virtual library a social meeting place and a place for study. All these diverse tasks and roles emerge in the democratic designing process of a new library and also transform into the architecture. The underlying process is the evaluation and negotiation of the libraries overall tasks and ideas, ideals and values. Multiple ideologies are incorporated in library architecture.
