With the increasing costs in concentrate the importance in producing ensilage with a high quality is becoming more and more important. To succeed with this goal it is of importance not only to harvest in the right period, but also to be able to store the ensilage without a decrease in quality and nutrional values. To maintain a good ensilage the covering of the ensilage must be carefully made. An unsuccessful covering causes mould to grow in the ensilage, which both increases the work load and also increases the amount of feed which is wasted. A bigger amount of spoiled feed also increases the risk of feeding spoiled feed to the cattle.

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

A third party access to district heating networks has been proposed in Sweden, to increase the competition on the district heating market. Such third party access could create opportunities for the agricultural sector as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel. The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant. In the study, an estimation of the profitability has been made by estimating the cost of the investment, personnel, operating and maintenance costs and costs for the fuel and ash handling.

Every day we make numerous decisions. Some are better than others. Intuitive decisions usually results in less good decisions when we do not reason about our choices. Research has been interested about the process that is behind how we make good decisions. Decisions we face every day, such as when we shop, determined using various mental shortcuts that we use unconsciously.

The aim of this report is to investigate how the work handling at the department for arriving goods at EFG in Tranås is working, as well as how it could be improved and made more effective. EFG is a corporation who process and sell office furniture. The company is working with a project concerning delivery precision, the subject is therefore particularly interesting from the perspective of delivery accuracy. The number of orders has increased notably during the fall of 2005 and the spring of 2006. This has led to new demands at the department for arriving goods and the topic is as a result of that important also from this point of view.Interviews and investigations have been conducted at location since no written material earlier has been made in the topic.

Background: Bone anchored hearing system is a surgically implantable system for treatment ofindividuals with hearing loss. The Softband is intended for patients who can benefit from a boneanchored hearing system but who are not yet suitable for implant surgery.Objective: The aim of this study was to investigate whether an adhesive bone conductor, Adjoin, canbe used as an alternative to Softband.Material and Method: Twenty adult subjects with normal hearing participated in the study.Measurement of functional gain and speech intelligibility was performed with Softband and Adjoinwhich then were compared. A questionnaire was answered by the participants after the measurementsthat treated their subjective experiences with each option.Results: The objective measurements yielded no overall difference between Softband and Adjoin forthe group studied. The subjective results showed differences in the perceived comfort as well as whichof the two bone conductors that would be preferred to use in everyday life, with Adjoin being thepreferred option. No difference was detected on participants perceived gain, sound quality and speechintelligibility.Conclusion: Based on the measured results, Adjoin seems to be a suitable alternative to Softband.However, there are questions about how Adjoin works with long-term use..

Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

Syfte: Att utifrån litteratur beskriva hur sjuksköterskor kan identifiera smärta hos äldre personer med demenssjukdom, samt att undersöka vilka mätinstrument som finns att tillgå för att beskriva smärta. Metod: Litteraturstudien var av deskriptiv design. Litteratursökningen gjordes i databaserna PubMed och Cinahl. Resultat: Resultatet baserades på 14 vetenskapliga artiklar som visar att det finns många uttryck för smärta som sjuksköterskan kan använda sig av för att identifiera smärta hos äldre personer med demenssjukdom. Resultatet visade att det är mycket svårare att identifiera smärta vid omvårdnad av äldre demenssjuka, då de inte kan kommunicera som kognitivt intakta personer.

I have together with Frimeko AB developed new hallway furniture for preschools. The background to the project is the fact that all the existing hallway furniture?s on the market today have a similar design and same features. None of the furniture stands out immediately. Companies who work with school furniture in general have been inspired by each other, and therefore is the collections monotonous.

Today every organization is committed to some kind of environmental scanning in order to get necessary knowledge of the world around them. The acquisition, organization and storage of information in combination with a strategic use, is today an important factor for a successful organisation in any sector of our society.In this Master thesis I have studied how an organisation such as The Confederation of Swedish Enterprise (Svenskt Näringsliv) handles its information resources. I have also looked at the flow of information within the organization. The Confederation of Swedish Enterprise is Sweden?s largest business federation representing 50 member organizations and 55 000 member companies.

Nederbördsmätning är viktigt inom många områden och en relativt ny teknik är enoptisk distrometer som med hjälp av laserteknik mäter nederbördspartiklarnasdroppstorlek och fallhastighet. Syftet med detta arbete var att undersöka hur välThies distrometer stämmer överens med nederbördsmätning från ett vippkärl ochmanuella mätningar från institutionen för geovetenskaper vid Uppsala universitet.Institutionen för geovetenskaper överväger att gå över till denna teknik och därmedbehövdes distrometern utvärderas för olika faktorer som kan påverka instrumentet.Vid jämförelse mellan instrumenten visade det sig att distrometern totalt sett samladein mer nederbörd än de andra mätarna. Det är svårt att avgöra vad skillnaden mellaninstrumenten kan bero på men felkällor så som avdunstning och vätning hos vippkärletoch manuella mätningar kan ge mindre nederbörd. En annan orsak kan varafelkalibrering av datan från distrometern. Inga samband hittades för vindhastighet,vindriktning och typ av nederbörd mellan de tre instrumenten.En vidare undersökning gjordes för droppstorleksfördelningen för att ge exempelpå fördelar med en distrometer.

In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.

The purpose of this Bachelor?s thesis is twofold. Firstly it aims to make a contribution to the understanding of how five Swedish Diocesan libraries have carried out the digitizing of their rare book and manuscript collections. Problem areas related to this activity are also investigated. Secondly, it aims to examine the relative guidelines and standardization norms, which have been formulated on a national basis.

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

En säker bakteriediagnostik kräver en korrekt provtagningsteknik, ett lämpligt transportsätt och rätt odlingsteknik. På grund av centralisering av verksamheter och ekonomiska begräsningar, är transport av prover till mikrobiologilaboratorium mycket vanligt. Detta medför behov av ett transportmedium som håller känsliga bakterier vid liv under långa transport- och förvaringstider. Dessutom skall transportrören klara av maskinell utodling som kräver ett vätskebaserat provtagningsmedium. Denna övergång minskar även arbetsbelastning och förbättra ergonomin hos personalen.
