Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

Syftet med föreliggande studie var att undersöka om det fanns könsrollsskillnader i kroppsuppfattning och självkänsla utifrån könsrollerna maskulinitet, femininitet ochandrogynitet, om det fanns samband mellan kroppsuppfattning och självkänsla och även omdet fanns skillnad mellan könen gällande de två variablerna hos gymnasieelever (n = 79). Könsroller mättes enligt formuläret Bem Sex-Role Inventory SE ? BSRI-SE,kroppsuppfattning i enlighet med skalan Body-Esteem Scale for Adults and Adolescents ?BESAA och självkänsla enligt Rosenberg Self-Esteem Scale ? RSE. Resultatet visade attmaskulinitet korrelerade positivt med kroppsuppfattning och självkänsla. Vidare fanns ettnegativt samband mellan femininitet och kroppsuppfattning och självkänsla och gällandeandrogynitet fanns ett positivt samband med självkänsla.

Environment and sustainable development are very current topics in today's society, bothnational and international. The government's bill 2004/05:150 ?Swedish environment objectives - a common commission? contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: ?Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment.

Cambodia is located in Southeast Asia with a tropical monsoon climate and distinctive wet and dry seasons. Poverty is a widespread problem in Cambodia and 30 percent of the population were classified as poor in 2009. About 80 percent of the populations live in rural areas where poverty is an even greater problem. In agriculture, rice cultivation is dominating and the crop is cultivated on 85 percent of the arable land. Livestock keeping is also a traditional part of Cambodian agriculture.

The purpose of this study was to exam the possible differences in the experienced self-confidence and motivation among the elite players in bandy and amateur players in bandy. In addition, any differences between boys and girls within the same area to be studied. A total of 112 athletes participated of whom 52 of them classified as elite players and 60 amateur players, with 62 boys and 50 girls. The athletes filled at one point in the questionnaires The Sport Motivation Scale, Harter?s (1980) ?competence scale? and The Sport Confidence Inventory.

Det perfekta kroppsidealet gör sig ofta påmind i samhälls- och mediadebatten. Dagens västerländska kroppsideal domineras av en smal och fettfri kvinnokropp. Under tonåren är fokuseringen på kroppen mer påtaglig än under någon annan del i livet. Strävan efter det slanka idealet är svårt att uppnå och kan medföra att individen inte förmår att acceptera sin kropp. Syftet med denna studie var att få en bild av och jämföra kroppsuppfattningen hos unga kvinnor som går på gymnasiet i Luleå respektive Jokkmokk.

This is a Master´s Thesis based on my own idea instead of that of a company. It is a survey that focuses on finding out more about which part of the development process that is blocking the establishment of electronic scorecards on the golf market. Why has it not been introduced on the market in a larger scale yet, considering the technology we possess today? This question is investigated through interviews with the Swedish Golf association, and three companies that have chosen different paths to implement an electronic scorecard. The interviews focuses on finding out what developers and the association believe to be the main problem, before taking the next step in releasing electronic scorecards on a larger scale.

This thesis presents the results of the implementation and evaluation of two machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi cation methods. The results of the evaluation did not match those obtained by the original authors.

Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

 Tidigare forskning inom studentliv och studenternas framgång är ett väl undersökt område. Könsskillnader, känsla av sammanhang (KASAM) och socialt stöd är några av de faktorer som har visats påverka studenternas akademiska self-efficacy. Studiens syfte var att undersöka relationen mellan kön, KASAM, socialt stöd och studenternas akademiska self-efficacy. 124 högskolestudenter i Mellansverige deltog genom att svara på en enkät bestående av College Academic Self-efficacy Scale, Social Support Questionnaire 6 (SSQ6) samt Sense of Coherence scale (SOC-13). Materialet analyserades med Pearsonkorrelation, regressionsanalys och t-test.

This thesis is about informal seatings, those which are planned to merge into the city core environment and to supply a flexible public space. The thesis discusses how a diverse range of elements could result in different functions and social meanings. These are illustrated with visual examples and conceptual drawings. The position of the seating in a small public place is important, as well as its location in the city. Furthermore, the detail design of the seating, such as the form and dimensions have to be considered in order to create an informal seating appropriate for the user. This leads to the broad scope of this thesis which deals with the small scale - how the seatings can create a good environment in a small place; and the big scale - how a site can influence the city. This thesis suggests the physical design of some informal seatings and also investigates how these seatings can strengthen the place through their function and how they relate to their surroundings.

This master thesis aims to investigate and quantify the potential associated with increasing the usage of edible by-products as food for human consumption on the Swedish market. The main emphasis is on the Swedish production of offal and the obstacles that currently inhibit greater usage of these products as foods.The results indicate that the Swedish market for offal is limited. Only a small amount of the edible by-products that are produced in Sweden every year are consumed as foods and a considerable amount seem to be downgraded into animal feed or thrown away. The utilization of these products is restricted by economical, technical, legal, and cultural factors that all need to be taken into consideration. On the whole, large-scale slaughter plants seem to be more inclined to utilize these products effectively, as the profit from doing so increases proportionately to the produced volumes.

Stroke is caused by a bleeding or infarct in the brain and is one of the most common diseases in Sweden today. The purpose of the study was to evaluate if Ronnie Gardiner?s Rhythm Therapy (RGR-therapy) has any effect, regarding motor control and the subjective experienced health related quality of life, on people who have been affected by stroke. The examination group consisted of eight people. The intervention consisted of RGR-therapy once a week during a period of nine weeks.

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.
