Junior : utveckling av barnglasögon för Polaris Eyewear AB
Polaris Eyewear is one of the world's leading companies in innovative eyeweardesign. My assignment has been to, in collaboration with them, expand their range with a pair of children's glasses, while maintaining the innovative character they are so known for.The problem with childrens eyewear today is that most of the time the glasses tries to mimic the adult eyewear and the ?childish? type of designing is spared. From an ergonomic point of view, a child's nose is smaller than an adults and therefore needs a different type of shape and nosebridge. In addition, children have softer ears, which means that they need a different type of shaftend as well.

Slaktsvins basala behov i kommersiell uppfödning : Slaktsvins basala behov i kommersiell uppfödning oönskade beteenden, skador och välfärdspåverkan
The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

The healing process of human bone can be aided by the presence of differentmaterials. A material that is transformed into bone when in contact with bone iscalled a boneconductive material. By transforming into bone the material reduces thetime that it takes to heal a fracture. This report is a study of existing boneconductivematerials on the market to see if there is a material available that would be suitable totest on larger fractures. The wanted application is to be able to heal fractures up to50 mm which is a fracture too big for the body to heal on its own.The healing process of human bone can be aided by the presence of differentmaterials.
Evaluation of a standardized platelet concentration in samples from platelet concentrates measured over time with impedance aggregometry
Platelet transfusions can be necessary during treatment of patients with thrombocytopenia or impaired platelet function. Platelet function in platelet concentrates (PC) deteriorate with storage time. Studying swirling is often used to control the quality of PC?s before transfusion but the method has some disadvantages. Therefore other methods can be useful, for example impedance aggregometry (IA, Multiplate® Analyzer) to measure platelet function. In this study the change in platelet function over time was examined in buffy coat and apheresis platelets with IA where aggregation had been induced with adenosine diphosphate (ADP) and collagen.
SAB och Dewey vid Uppsala universitetsbibliotek : En attitydundersökning bland bibliotekarier på 6 biblioteksenheter
The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.
Selecting plant species for the occasion of the 300th anniversary of Carl von Linné at Möckelsnäs :
This report was an outcome of a cooperation between ?The Visitor and Knowledge Project Carl von Linné? and SLU, the Swedish University of Agricultural Science. The aim with the cooperation was to create a garden and to suggest suitable plants for an orangery already built. All species suggested should have a documented relationship with Carl von Linné. The project is located in the southern part of Sweden at an estate named Möckelsnäs not far away from Linné?s birthplace.
Att dela eller inte dela? : Vad som möjliggör respektive förhindrar produktdelningssystem
Product sharing systems is recently starting to become a more common phenomenon. Carpools exist in more than 40 Swedish towns and both Stockholm and Gothenburg have established bicycle sharing systems. Other products for which sharing systems have been established throughout Sweden are clothing and tools. From the point of view of the consumer, product sharing systems is a form of consumption which can be placed somewhere in between renting and privately owning a product, where the consumers usually pay a membership fee or a monthly fee to have access to the products whenever they need them. The concept is relatively new, and there are many products for which product sharing systems do not exist.
Full Circle: upstream and downstream migration of Atlantic salmon (Salmo salar) in the northern Swedish river Vindelälven
The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.
Arbetslöshetsförsäkringen och individen : en studie om krav, skyldigheter och hänsyn ur perspektivet geografisk rörlighet
This paper describes the rules of the Swedish unemployment insurance as regards the demands on the individual, the obligation posed on the individual based on these demands and the considerations taken by the law regarding the specific situation and personal circumstances of the individual. Special attention is paid to the demand to be available to the labour market and what is considered suitable employment from the viewpoint of geographical mobility. This paper treats ?Arbetslinjen? (Everyone able to work, thereby contributing to his/her own and others' support, shall have the opportunity to do so.), and the amendments of ALF, the law (1997:238) about unemployment insurance, that became active between 1/1 2007 and 1/1 2008, since many alterations were introduced in this period.The result illustrates the demands posed on the individual for him/her to be entitled to unemployment benefit, and the far-reaching demands posed on the unemployed for him/her to be considered available to the labour market from the viewpoint of geographical mobility. The result also shows some of the specific situations and personal circumstances of the individual taken into consideration, but since the amendments are as recent as 1.5 years, the list can not be considered complete, as practice is limited in this field.This paper also treats the Official Employment Agency's monitoring function of the unemployed's willingness to work, and the effect of the regulations not being followed as strictly as per the letter of the law by the Employment Agency officers, leading to insecurity regarding the rights of the individual..
Givarkonstruktion för beräkning av sådjup
This report shows the process of the development of a sensor module for the seed drills of Väderstad Verken AB. The module is supposed to replace existing solutions, provided that it is better from both a constructional- and an economical aspect. The purpose of the sensor is to continuously give the driver information about the level of height of the front- and drilling tools and the main purpose of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67.The methods applied have been taken from the book ?The Mechanical Design Process? by David G.
Hur påverkas kolesterolvärden hos postmenopausala kvinnor med hyperkolesterolemi vid intag av isoflavonoider?
Sahlgrenska Academy at University of GothenburgDepartment of Internal Medicine and Clinical Nutrition3AbstractTitle: How does isoflavones in combination with soy protein impact cholesterol levels in hypercholesterolemic postmenopausal women relative to milk protein?Author: Emma Edberg och Emma NilssonSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician stydy programme,180/240 hpType of paper: Examination paper, 15 hpDate: 2014-05-26Background: Hypercholesterolemia is a major risk factor for cardiovascular disease and the number one cause of death among women in Western countries. Declining levels of estrogen at menopause could be a contribution factor. Isoflavones is a vegetable substance, with structural and functional similarities to the human estrogen. This is a potential reason for possible cholesterol-lowering effects.
Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos
This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.
The diffusion of minimum tillage in agricultural China : a study of the factors influencing the farmers? choice of tillage system
The Chinese government´s aim to be self-sufficient in food production in combination with the increased food consumption in China has put high pressure on the productivity within the Chinese agricultural sector (He j et al, 2010). In order to increase the productivity, modernization and adoption of new farming techniques are essential. The opportunity to adopt and import foreign technology has lately been possible in China, as more authority and decision rights have been given to the individual farmers and the country has opened up for foreign trade (Zheng, 2012 & Fan, 1991).
A more open Chinese market enables new opportunities for foreign agricultural companies to expand their businesses by introducing their products to Chinese farmers. But to succeed with this strategy the Chinese farmers must be willing to adopt these, for them new innovations.
Minimum tillage is a tillage practice used worldwide that is suitable in northern China where drought and erosion are the main problems in the crop production (pers.com., Arvidsson, 2012).
Potential users? opinion of new innovations such as minimum tillage is closely related to adoption (Rogers, 2003).
Teknisk och ekonomisk analys av en bränslekonvertering vid SIA TallOils pelletsfabrik :
At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant
Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.
