As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Ever since Internet revolutionized the world, e-stores and e-commerce has grown into becoming a natural part of consumer's everyday life. Much thanks to it's facilitative and time saving characteristics. Online, consumers are provided with a huge assortment and the opportunity to shop any time they like. Yet, the absolute greatness of e-stores is the possibility to push prices below the physical store price, which seems to be most appreciated to a large extent by consumers worldwide. The fact that e-store sales in Sweden grew 14% last year verifies this.As more players step into the virtual world of e-commerce the competition gets tougher.

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

Lately it has become more common to question the companies? actions in how they affect their surroundings. Today, the expression ?Corporate Social Responsibility? often is mentioned in this connection. Corporate Social Responsibility (CSR), is a concept whereby companies voluntarily integrate social and environmental concerns in their business operation.In Sweden there is a big difference between different businesses when it comes to their Corporate Social Responsibility.

City of Malmö has ambitions for the district Hyllie to become a demonstrative area ofsustainable urban development. As a part of this the following report aims to investigate the potential in using noise barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and how they change over the year. A reference model of a photovoltaic noise barrier (PVNB) was constructed and used to find the dates on which the solar cells are shadowed depending on building heights and positioning of the barrier.The results show that two lengths with a total distance of 400 meters is appropriate for applying photovoltaic noise barriers.

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

This is a qualitative analysis that, based on systemic functional linguistics, or SFL, and genre theory, has aimed to study the genre pedagogical implications on written language as they occur in narrative stories and expositions whilst the model is introduced. Systemic functional linguistics is a linguistic theory that views the organisation of language as functional options for meaning; language is a set of resources to channel meaning through realisation. Genre theory elucidates the pragmatic and educational uses of SFL in the categorizing of language in configurations of meanings as they are set and understood in different cultures.  The purpose of the survey is to do so with focus on successful and less successful writers by attempting to answer two primal issues:How is development of written language in reference to the introduction of the genre pedagogical model visible in the studied texts?How does genre pedagogical teaching influence successful and less successful writers as visible in their writing with a certain purpose?To answer these issues the survey is based on narratives and expositions written by high school students who have been divided into two groups according to the purpose of the survey. One text in each genre has been written by the students before and after lessons based on the genre pedagogical learning wheel explaining the relevant genres.

Background: Today, the trademark is the heart of the company and the management of brandimage and identity require certain attention and care. In an increasingly tough business climatewhere the brand today has a central and important role, it is understandable that the companieswant to take maximum advantage of it. In the company the brand is a great resource with analready known identity and established values that can help new products to enter the market. Toextend the brand is a popular growth strategy but it is important to do it properly in order not tofail. J Lindeberg and Peak Performance are two Swedish fashion companies which both havemade brand extensions.

The aim of this report is to increase the knowledge and understanding of the problems within the production at AQ Enclosure systems, and thereby achieve a more stable flow throughout the whole process, a better working environment and better competition advantages. The internal flow along with the external cooperation is very important for the company, because it views flexibility and short leadtime as it is the most important competitive means. The part of AQ production that?s been investigated is the manufacturing of ATM-machines, where the costumer is Banqit. This company is a rater small company with about 4 % of the world market of ATM-machines.In order to achieve the aim of the report extensive interviews have been carried out with employees at AQ.

Syfte & problemområde:Syftet med denna uppsats var att undersöka hur dagens vuxna barn upplevt deras uppväxt i en familj med alkoholmissbruk. Jag ville även studera hur dessa personers nuvarande livssituation såg ut, och hur den påverkats av den specifika uppväxten, med en missbrukande förälder.Metod & material:Studien är en kvalitativ intervjustudie, där empirin har samlats in genom intervjuer med fem vuxna barn till missbrukare. Materialet tolkades och problematiserades utifrån ett systemteoretiskt perspektiv med fokus på familjen, och stämplingsteori med fokus på individen.Resultat & slutsatser:I resultatet framkommer det att flertalet av informanterna blev varse om att någonting inte stod rätt till vid 8-9 års ålder. Gemensamt för nästan alla som barn var känslorna av skam och kluvenhet över situationen med en mamma eller pappa som missbrukar.I fyra av fallen så fanns det en önskan om att fly eller hålla sig borta, men samtidigt en ambivalens gällande deras frånvaro, tre av dem kunde känna oro för föräldern eller syskon, medan den fjärde kände förväntningar på sig om ansvar i hemmet. Även känslor av ensamhet, utanförskap och dåligt självförtroende var typiska, känslor som kunde styrkas genom tidigare studier och kan eventuellt tolkas ses som representativa hos barn till föräldrar med alkoholmissbruk.

During the middle of the 18th century the development of Toyota Production System, TPS, started in order to streamline the processes. TPS was based on the principles of assembly line production but unlike previous performers Toyota let the manufacturing be constantly affected by demand. At the end of the 18th century TPS was described by Womack and Jones in the book "The machine that changed the world - the story of lean producion" where TPS got the name lean. The principles behind lean is to maximize customer value and eliminate waste which means making products and services more valuable to the customer. 1Lean was for a long time a philosophy and an approach limited to industries and production based companies.

Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.

A new phonological test, LINUS, for Swedish-speaking children between the ages of three and seven, has been developed at the speech and language pathology department at Linköping University. The aim of the present study was to create a reference manual for the long version of the new test. The participants in the present study were children between the ages of five to seven in a medium-sized municipality in the Northern part of Kalmar County, Sweden. In total, 124 native Swedish-speaking children (58 girls and 66 boys) with typical language development participated. The children were divided into two age groups, 5;0-5;11;31 and 6;0-6;11;31 years.

This EEF-project is a part of a larger project at SLU, Division of Reproduction, Dept of Clinical Science, with the intention of developing and evaluating new methods for the assessment of stallion semen quality. Over the last 10 years there has been an increase in the use of artificial insemination with cooled semen in Swedish horse breeding. At the same time, foaling rates have decreased. This has lead to a need for new and better methods of assessing the quality of stallion semen. This EEF-project was based on an objective method to calculate motility, with QualispermTM, in fresh and cooled stallion semen, and after selection. Today sperm motility evaluation is mainly done subjectively by visual assessment with a light microscope, and the correlation between these motility results and fertility have varied.
