The idea behind this project came from a feed study executed two years during the lambing season. Both years wool loss was experienced. Low temperature in combination with shearing was believed to cause the wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for wool loss and how common wool loss is in Swedish sheep herds.

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

Today, the tourism sector is the fastest growing industry in the world and also includes one of the foremost for instance in the number of work and added tax. The sector entails a lot of positive factors but also negative consequences, such as overexploitation and wear on natural areas. However, even the visitor industry contributes to smaller localities boost by creating new jobs where depopulation occurs. This study focuses on the town Kisa in Kinda Municipality. The purpose of the study is to highlight the importance of tourism for migration to a town and to show the importance of developing sustainable destinations.In the results of this study it emerges that more job opportunities are requested by respondents for increasing Kisas attractiveness.

Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.

Webbapplikationers komplexitet och mängden avancerade tjänster ökar. Loggning av aktiviteter kan öka förståelsen över användares beteenden och behov, men används i för stor mängd utan relevant information. Mer avancerade system medför ökade krav för prestandan och loggning blir än mer krävande för systemen. Det finns behov av smartare system, utveckling inom tekniker för prestandaförbättringar och tekniker för datainsamling. Arbetet kommer undersöka hur svarstider påverkas vid loggning av serverdata, enligt datainsamlingsfasen i web usage mining, beroende på lagringsstrategier.

I detta arbete studeras hur vinterklimatet i Sverige kommer att skilja sig åt mellan perioderna 2071-2100 och 1971-2000, med avseende på parametrarna temperatur, nederbörd, vind, snödjup och snöutbredning. Klimatmodelldata (CORDEX) i upplösningen 12.5 km baserade på tre olika strålningsdrivningsscenarier (RCP-scenarier) behandlades i Matlab och modellerades över Sverige. För att analysera upplösningens betydelse tillhandahölls även data i upplösningen 50 km för en tioårsperiod. Scenariot RCP 8.5 kan ge så mycket som 10 grader varmare vintrar, med uppemot 50% mer nederbörd. För RCP 2.6 förändras nederbörden med -5 till 20%, och temperaturen ökar med 1-4 grader.

Detta examensarbete har genomförts vid Mälarenergi Elnät AB i Västerås. Undersökningen föranleddes av regeringsbeslutet om att elmätare måste avläsas en gång per månad från 2009. Konsekvensen för Mälarenergi är att de måste investera i ett automatiskt mätinsamlingssystem. Syftet med projektet har varit att skapa en generell investeringsmodell för att ekonomiskt utvärdera ett antal mätinsamlingssystem. I rapporten har Milabs, Seneas, Enermets, HM Powers, Iprobes samt Techems och Viterras system analyserats.

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which harvesting methods that have been tried in Sweden and how they worked.

Det här är en studie kring ämnet flexibel utformning av offentliga rum, och ett förslag på hur Båstads hamnområde skulle kunna utvecklas till en plats som på ett mer tillfredsställande sätt kan användas året runt. Idag är hamnen en plats som präglas av några månader med intensivt liv och mycket rörelse under sommaren, för att sedan bli en tom och oanvänd plats vintertid. Förslaget har föregåtts av analyser, både under vinter och sommar, av hamnens rumslighet, aktivitet, rörelse och attraktioner, en litteraturstudie kring ämnet flexibel utformning av offentliga rum, samt två studiebesök på mindre orter i Sverige som kämpar med en liknande problematik. Förslaget har också föregåtts av en inventering av området, samtal med tjänstemän på Båstads kommun och näringsidkare i hamnen samt studier av tidigare planprogram och planer för hamnen framtaget av kommunen. Med utgångspunkt i resultaten av analyserna och med inspiration från litteraturstudien och studiebesöken har jag tagit fram ett förslag på hur Båstads hamnområde skulle kunna utvecklas, göras mer flexibelt och därav mer användbart hela året.

Platelet transfusions can be necessary during treatment of patients with thrombocytopenia or impaired platelet function. Platelet function in platelet concentrates (PC) deteriorate with storage time. Studying swirling is often used to control the quality of PC?s before transfusion but the method has some disadvantages. Therefore other methods can be useful, for example impedance aggregometry (IA, Multiplate® Analyzer) to measure platelet function.     In this study the change in platelet function over time was examined in buffy coat and apheresis platelets with IA where aggregation had been induced with adenosine diphosphate (ADP) and collagen.

The need for a more efficient electrical grid has made the smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a smart grid and to analyse the opinions of stakeholders. One finding is that the large capacity of Sweden?s existing electrical grid decreases the immediate need for smart grid solutions. However, the rapid increase in wind power might push the development of a smart grid in the coming years.

This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.

It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006).  Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage. In this paper we have tried to find out if reduced tillage is an alternative for farmers.
