Förbehandlingstekniker och LCA för rötning av organiskt avfall : Modellkonstruktion och Utvärdering med ORWARE

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

Affischen - Ett döende medium? : En kvalitativ studie av evenemangsaffischering

As students of graphic design the craft of print is close to our hearts. One of the most essential mediums of the evolution of printing techniques is the poster. In a world where digital mediums are being utilized to a greater degree everyday, our love for the printed poster makes us wonder if the days of the poster are counted.What we did was to take a closer look at the role of the poster in promoting events. We focused on the Stockholm area and did qualitative interviews with three different event promoters. Live Nation which is an international live entertainment promoter, Dramaten which is one of Sweden?s most well respected theaters and Stockholm Live which is a stand up comedy promoter in Stockholm city.From doing this we learned that economics play an important part in defining the role of the poster.

Utvärdering av digitala provtryckssystem

Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.

Survey of regulations concerning pesticides in Sweden and the EU : cultivation techniques and competition aspects for Swedish onion and apple producer

As a member of the EU, Sweden has, in some cases, transferred the controlling rights to the Union. This means that the rules defined by the EU must be followed in all member countries, including Sweden. The European Agricultural policy constitutes the largest part of the EU's annual budget and is in contrast to many other areas fully funded at EU level. The last decade, many new regulations on chemicals and pesticides have been introduced which brought great changes and a lot of work throughout the Union, including Sweden. Sweden has always had a strict policy on chemicals and has been at the forefront when it comes to sustainable agriculture and environmental management.

Vindpark Vänern : Fundamentteknik och Logistik

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Att motivera elever

Middle managers in social care find themselves in a middle position. The middle management position involves demands from several interested parties. The demands affect and generate feelings both within themselves and within others and the middle managers have to deal with them all.The aim of this study was to investigate the social care middle manager?s personal experiences of emotions in work.We have completed interviews with four middle managers who are assigned to carry out social care. When doing the interviews we used an interview guide divided into different interview areas.

Mars och Venus i cyberspace ? genusmönster i bloggen

The purpose of this thesis is to find out if people have changed the way in which they write since the introduction of the internet. Men and women have been writing books, articles, letters, diaries and different types of literature for centuries. To give the reader some background about the weblog as a literary media, this thesis has a whole chapter on half-public literature that includes the history of letters and diaries. The weblog is a unique way for anyone to be whoever they want, whether it be a man or woman, old or young. The reader has no possible way of knowing if the script is true or not.

Big Bath Accounting och bonus i börsnoterade företag

A company may use different accounting techniques to adjust accounting information and thereby attract investors. Big Bath Accounting is defined as a strategy used to make changes in the financial statements and reduce the results further when the companies expect negative results. This phenomenon has been observed empirically and occurs when including CEO change and negative results. The aim of this study is to test whether there is another factor affecting Big Bath Accounting, namely remuneration of the CEO. The CEOs should, by changing the accounting information, be able to influence their compensation.

Se men inte röra : Röntgen som verktyg i dokumentation av historiska stoppningar.

How can we use modern X-ray technology to raise awareness of the information that is hidden in historic upholstery? The materials and techniques add information to the history object in question and  about a profession that is sparsely documented in our country. The knowledge we have today has largely been obtained by studying damaged upholstery, or by removing the show cover and upholstery, a technique which involves high risk of damaging the upholstery. X-ray technology offers  a non- intrusive way to examine historical upholstery.Through case studies, I examined four artefacts. The artefacts went trough an inititial visual exam before being transported to The National Heritage Board in Visby where they underwent a thorough X-ray exam.

Är klassröstningen fortfarande signifikant? - en studie om kommunalvalen i Stockholm och Göteborg 2002

The association between social parameters (i.e. socio-economy and level of education) and voting behaviour has been reviewed and analysed based on data from municipal council elections in Stockholm and Gothenburg in 2002. Some social scientists argue that the class voting is in decline and that new social cleavages have emerged. However, by using regression analysis techniques, this study implies a strong dependence of voting behaviour on social parameters, such as socio-economic status (SES) and level of education. Socio-economy appears to be a dominant predictor in the analysis.

Diurnal rhythm of the savannah elephant (Loxodonta africana africana) in Maasai Mara National Reserve, Kenya

Elephants are hindgut fermenters, which affects their diurnal rhythm. To reach their nutrient demands, elephants must eat almost constantly throughout the light part of the day. Sexual dimorphism may also affect their behavioral patterns. To understand the elephants' normal living habits and foraging behaviour, we conducted a pre-study in the Mara Triangle, the north-western part of the Maasai Mara National Reserve. Each of four to six observers randomly chose a focal animal within the group of elephants by the criteria that they were adults and visible.

Visbys färger : exteriör färgsättning av bostadshus i Visby innerstad 1860?1930

The main aim of this research is to survey the general colour scheme for private dwellings inVisby, built 1860?1930. During this period the visual appearance of the town of Visby changedsubstantially, since the increased local production of lime led to the plastering of many woodenbuildings. Which colour schemes were chosen for the different building types of the historic centreof Visby, and which colours came to dominate the time period? The methods used for answeringthese questions have partly been field studies on site and sampling of selected buildings, andpartly critical reading and observation of iconographic material (paintings, drawings, aquarelles,postcards and photographs).

Relationer mellan kvinnor : Avund och konkurrens mellan kvinnor i Försvarsmakten

Syftet med denna studie är att undersöka kvinnors erfarenheter av konkurrens och avund kvinnor emellan inom Försvarsmakten. Tidigare forskning redovisar att friktioner mellan kvinnor skapas på grund av samhällets genusordning, att kvinnor är det underordnande könet vars prestationer inte värderas samma som männens.  Det visar sig också att kvinnors behov av bekräftelse och identifikation genom andra kvinnor skapar slitningar. En enkätundersökning ifylld av kadetter på alla Försvarsmaktens skolor visar att avund och konkurrens är ett tämligen vanligt förekommande fenomen. De kvinnliga kadetterna upplever att männen bidrar till att skapa avund och konkurrens kvinnor emellan. De uppger även att de i högre grad känner konkurrens gentemot männen på grund av att Försvarsmakten är en organisation gjord av män för män och en frustration bland kvinnorna är uppenbara på grund av kvinnors och mäns olika förutsättningar i Försvarsmakten..

Kvinnor, kriminalitet och könsmaktsordning : En kvalitativ studie om återanpassningsarbete på Färingsöanstalten ur ett genusperspektiv

This thesis explore women?s needs when reentering society after having served a sentence at the female prison Färingsö, outside Stockholm and whether those needs are being met in the reentry strategies that are being provided. Parallel to this the thesis also examines if there, based on nonconformity and gender theories, is a socially constructed representation of women maintained in the rehabilitation work.The method of this thesis applied semi-structured interviews and used snowball sampling to expand the network of informants to obtain the data necessary. Totally five interviews were carried out. Previous research has shown that women in prison have much more complex problems than men and that there is a need for reentry strategies that take gender in account.The results showed that in terms of being able to reenter back in society, women needed help to structure a previously chaotic life.

Dairy fat biomarkers and cardiometabolic health

Commonly held dietary guidelines discourage full-fat dairy consumption due its to high levels of saturated fatty acids, which are believed to aversely influence cardiovascular disease risk. Cardiovascular diseases cause more than one third of deaths in the developed world. With dairy often providing a large part of energy and nutrients in Western diets, research into its effects on human health is warranted. Several recent studies have suggested a protective role of dairy in the development of cardiometabolic disease. However, many of these have used imprecise methods of dietary assessment, based on questionnaires or interviews. Biomarkers are emerging as a means of evaluating diet in a more objective way. Currently used dairy fat biomarkers are minor fatty acid constituents of dairy that preferably are unique to dairy and not influenced by endogenous metabolism.
