Composition of fractions from air-classified wheat flour

The unique ability of wheat to produce leavened bread is mainly due to the gluten proteins present. As consumers are more and more attracted to bread with high fibre content the use of wheat gluten will also increase in order to obtain bread with good volume and appetizing characteristics. Air-classification is a technological method used to separate particles by size and shape by means of air-streams into two fractions, fine and coarse. When used on wheat flour it is known to alter the flour composition in the fractions obtained compared to the original flour. This method is not widely used in the milling industry but could possibly be of interest if protein rich fractions with favorable protein quality can be produced.

The aim has been the basis of the representation levels of society discern what is valued and given priority as well as the measures and the strategies used in implementation. The empirical data underlying the study is qualitative studies with respondents from a university, a hospital, a school, the Swedish Embassy and an organization in order to create an image of different levels in society means to implement preventive measures on HIV and AIDS to their citizens. The result demonstrates that there are clear shortcomings in its implementation guidance on prevention measures for HIV and AIDS as lack of resources is based.

Anpassad skötsel - exempel på hyggesfritt skogsbruk i Mellannorrland :

Total protection is often the option chosen when protecting forests with high environmental values. An alternative to total protection is application of management regimes that do not interrupt continuity of tree cover. This study focuses mainly on continuous cover forestry (CCF) in forest stands already protected. All objects are situated in the county of Jämtland in northwest Sweden. The purpose of the study was to attain a greater knowledge about CCF practices.

Undersökning av modulationsscheman för existerande bredbandsteknologier

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Effekt av tillskott med isoflavonoider från sojabönor på LDL-kolesterol hos vuxna - En systematisk översikt

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Effects of isoflavone supplementation from soybeans on LDL-cholesterol levels in adultAuthors: Malin Blomgren Alegria and Ruut ReivaaraSupervisor: Lena HulthénExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2013-04-08Background: One of the most common causes of death in Sweden is due to cardiovascular diseases such as heart attack and stroke. Hypercholesterolemia is one of the risk factors for cardiovascular disease. In Asia, hypercholesterolemia is less common than in the Western countries. In Asian countries, soy products are consumed in larger quantities than in the Western world, which has led to implemented research with the intention of examining soy's potential effect on cholesterol levels.Objective: To investigate whether there is scientific evidence that isoflavone supplementation from soy bean may have a lowering effect on LDL-cholesterol.Search strategy: The databases used for the systematic literature search were PubMed, Scopus and Cochrane. Keywords used were cholesterol and 9 versions of this, and isoflavones and 11 versions of that.Selection criteria: RCT articles, on humans, written in English, published from 2011 onwards, that focused on interventions with isoflavones from soybeans and its effect on blood cholesterol, the participants were over 18 years old and the study time was at least 24 weeks.

En studie av högskolebibliotekariers uppfattningar om distansstudenter som användargrupp

The purpose of this Masters thesis is to investigate how a group of academic librarians perceive distance learners as a user group. We have in our study been influenced by phenomenography, which is both a set of theoretical assumptions and a methodology. The theoretical frame of reference consists of Carol Kuhlthaus different levels of education and Michael Buckland´s information barriers. Using a qualitative method consisting of nine interviews with academic librarians and structural factor such as academic library policies, we have been able to conduct our study. The results of the study are presented in grouped categories of quotations that reflect various perceptions.

Förtroendeklyftan : politiskt deltagande och förtroende i Europa och Sverige

The purpose of this essay is to study causes for the lack of political trust in Europe and especially in Sweden. The essay starts with a presentation of two theories about the reasons for low political trust. Robert D. Putnam among others presents a theory that gives social capital an important role when viewing the low political trust. As Putnam sees it a person that participates in any kind of organization, political or not, develop trust for other human beings that in the long run affects political trust.

Optimering av informationsinsamlingvid prototyptillverkning

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Långa skuggor med shadow maps

Skuggor i 3D-miljöer är ett mycket efterforskat område, och detta arbete koncentrerar sig på shadow map-algoritmen. Det finns ett problem med denna algoritm, för då en shadow map projiceras på en yta som är större än sig själv så bildas stora trappstegseffekter, vilket kallas aliasing. Problemet som har undersökts är hur olika shadow map-algoritmer i en miljö med långa skuggor beter sig, där ett minimerat antal artefakter så som brus och aliasing är synligt. För detta undersöktes Percentage-Closer Filtering (PCF), som är en variant av shadow map, med olika samplingstekniker ? och även en vidarebyggnad med Percentage-Closer Soft Shadow (PCSS) implementerades.

Behandling av hanhundar med deslorelin :

This article presents a survey of male dogs treated with the gonadotropin releasing hormone (GnRH) agonist deslorelin (Suprelorin®, Virbac) at three animal clinics in central Sweden. Filled-in questionnaires from 110 dogs were received. The paper also includes a review of existing litterature concerning reproduction in male dogs, focusing on endocrinology, the effects of gonadectomy and the GnRH agonist deslorelin. Continuous treatment with deslorelin produces infertility in male dogs. The pituitary is initially stimulated by deslorelin leading to a rise in luteinizing hormone (LH) and follicle stimulating hormone (FSH) secretion. As a consequence the testosterone levels also increase temporarily.
