Texture is an important soil property and accurate particle size analysis of soil texture is therefore crucial. There are a number of well-established and newly developed methods available for determining soil texture. In order to compare the results of these methods, the differences between them must be determined. The difficulties, problems and differences regarding texture class determination were examined through a study performed on forest soil samples. The study compared different methods (pipette, hydrometer and field methods) and two types of dispersing agents (sodium pyrophosphate and sodium hexametaphosphate (calgon)) commonly used for particle size analysis.

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

The aim of this thesis is to study Viking Eggeling?s artwork Diagonal Symphony together with Eggeling?s own art theoretical writings. This method of reading Eggeling?s art theoretical writings with the aim to try and create a deeper understanding of his art and especially Diagonal Symphony is a new approach in Eggeling?s art historical discourse. The thesis starts with a description of how the field of art history has understood Eggeling and his art primarily through art historical research aimed at Hans Richter.

This study centres on learning to read and methods for teaching reading skills. The aim is to provide a survey of the concept reading skills and the methods developed on the basis of different theories and the methods preferred when teaching children in primary school and why. The study is based on interviews with eight teachers who are working on a dailybasis teaching Swedish in preschool class or lower primary school. The result of my study is that the majority of teachers do not use a specific method, but rather combine several different methods, thus adapting instruction to each individual pupil. .

Studier har visat att frivilligt barnlösa individer stereotypt har betraktats vara olyckliga och otillfredsställda, något som inte har fått vetenskapligt stöd. Syftet med den här tvärsnittsstudien var att undersöka om det föreligger några skillnader i livskvalitet och livstillfredsställelse mellan frivilligt barnlösa personer och föräldrar i den svenska populationen. Forskningsfrågan undersöktes med en enkät som bestod av självskattningsskalorna QOLI (Quality Of Life Inventory) och SWLS (Satisfaction With Life Scale). 130 deltagare genomförde studien varav 54 är frivilligt barnlösa individer och 76 är föräldrar. Studien visade att det inte finns några signifikanta skillnader mellan grupperna med avseende på livskvalitet och livstillfredsställelse.

Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

The object of this examination project is to produce a method of work sampling at Rapid Granulator AB. The aim is to perform the method at the company and evaluate if it is executable. The study is delimited to the basic construction of the 45-series in the assembly hall.Preparations to produce the method of the work sampling resulted in definitions of activities, a form and a product tree. Several days were spent studying the assembling to learn and understand the entirety.The work sampling result showed a large amount of no value adding time that was used in the assembling. Some of the activities could be reduced and we observed some problems during the assembly process.

The electronic music studio ?Elektronmusikstudion? (EMS) inStockholm was initiated in 1963. It has had several different managers throughout the years. EMS soon became a rather costly project. Furthermore there have been several conflicts among staff and users wich has contributed to EMS fairly turbulent history.

Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction.

During adolescence the teenager tries to become an independent individual, something that for many individuals can be experienced as"a hard time". In early childhood the individual was closely connected to the parents, but during adolescence friends and new contacts become more important. Studies in developmental psychology have most often adopted a parent-perspective, which is why a child-perspective is required. The aim of this study is therefore to measure the teenager's relationship with parents and friends and to look for possible correlations between these. As a means of measuring quality in the relationships, the IPPA, the Inventory of Parent and Peer Attachment, was used.

Swedish school children exhibit deteriorating knowledge results in terms of reading comprehension. Previous research shows that a method to increase the level of knowledge is the use of evidence-based learning techniques. Test based learning generates what is commonly referred to as a test effect, which proved to strengthen the relationship between learning and memory, as well as being applicable to various test formats. The purpose of this study was to investigate whether test based learning, in terms of learning english words leads to increased performance in a reading comprehension test, more specifically a cloze test. The study was based on a within-group design and was conducted three times over four weeks.

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.
