Kan ett ökat intag av omega-3- fettsyror påverka testosteronnivåer hos kvinnor med PCOS?
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Can an increased intake of omega-3 fatty acids have an effect on testosteronelevels in women with PCOS?Author: Ylva Dernbrant och Helene HagenborgSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundPolycystic ovary syndrome affects women of fertile age and consists of elevated testosterone levels and increased insulin resistance along with effects on ovulation and fertility. The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.
Scalable Services over DAB and DVB-T from a Receiver Point of View
TV and radio services have always been distributed over analogue broadcasting networks and been received on a TV -set or a radio receiver. Today this situation is changing due to digitalization and convergence between broadcasting, telecommunications and data communications. Other terminals, such as a PC, can also receive TV and radio services. Digital TV and radio can offer additional services such as e-commerce, electronic program guides and content synchronized to the TV and radio shows. If these services are to be received by several receiving terminals with different properties, the services must be adapted to the terminals.
Oljetemperaturens inverkan på motoroljans degradering i lastbil
The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.
Meeting, greeting & seating : a design proposal for Magomeni garden, Dar es Salaam, Tanzania
More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations.
Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist.
There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.
Att bryta isoleringen - sociala faktorer i nätbaserad distansutbildning
Detta projekt fokuserar på distansstudenter och deras studiesituation i tre
nätbaserade kurser. Genom en empirisk studie bestående av samtal med studenter
och lärare, samt deltagande observation, har vi försökt finna lösningar för att
förbättra studenternas lärandemiljö. De sociala faktorerna visade sig vara av
stor betydelse i en studieform som tidigare kännetecknats av isolation mellan
studenter och lärare. Projektet visar på hur en nätbaserad utbildningsplattform
genom enkla tekniska lösningar kan ta hänsyn till studentens behov i fråga om
att stödja kommunikation och samarbete..
Hur långt bär cykeln? : Gång och cykling i Västerbottens län - en studie av pågående arbete med regional gång- och cykelplanering
The craft of planners are planning for a better future. Knowledge about climate change, environment, health and availability effects the trend towards less car dependent societies in favour of public transport and active transport like walking and biking. This study takes place in Västerbotten, one of Sweden?s most north provinces with a population of 260 000 inhabitants. It is a sparsely populated area with two dominant cities, the other municipalities are largely unpopulated.
Revisorns oberoende : en historisk skildring utifrån skandaler inom näringslivet
We have performed a historical research, trying to establish the auditing conditions, in terms of adjustments over time. Our purpose with this essay was to demonstrate the facts behind the independence of the auditor, and hopefully give the reader some new information.Our questions at issue were: What in the debate, regarding the independence of the auditor, in concern of the scandals, is most relevant each decade?Witch aftermath has influenced the regulation regarding the independence of the auditor?What we thought was the best way to answer this question was to study a large amount of journals according to the current decade, since 1930 and forward. The journals presented different persons opinions regarding the scandals, and we used them as an instrument to analyse the regulations and after-effects of the scandals.Our conclusion is that in purpose to make the auditor independent, the debate among competent and well-informed people in the line of business has, through the decades, frequently recurred to strive towards a more homogenous auditing..
Hur säkerställs effekten av marknadsföring när den outsourcas?
Outsourcing is today a common phenomenon among businesses in most industries. The term outsourcing means transferring the responsibility of performing a certain function to an external supplier. There are usually certain methods to investigate the effects and the outcome of a function that is performed by the company itself. When this function is performed by an external party, the complexity of the function will increase.This leads us to our purpose: Based on different theories clarify how a company ensures a desired effect out of marketing when this function is outsourced to a certain retail- and advertising agency.In this essay we have defined us to study one of Sweden´s leading mobile operators who have outsourced their sales management to a retail- and advertising agency. To get an additional point of view, we have included one of the mobile operator´s intermediates, which is a selling agent whose sales function is led by the retail- and advertising agency..
Informationalismens Murar hotet mot information som positiv rättighet; en ideologianalys av WTO och dess avtal.
This thesis examines the ideological implications of an emerging shift in human rights-issues regarding information. As Intellectual Property becomes increasingly important to the economy of developed nations previously commonly owned or unprotected information runs a real risk of becoming privatized. The World Trade Organization and its binding agreements GATS and TRIPS are subjected to a critical ideology-analysis, with special efforts to elucidate possible effects on the public service realm and its commitment as provider of free information as a human right. The result suggests that not only does a threat to information as such a right exist, but that its ideological basis however seemingly rooted in a liberal/neoliberal context actually in its express views on information deviates from liberal/neoliberal theory in many ways, and that there are theoretical inconsistencies in that same ideology..
Rekommendationer eller konversationer - Effekten av innehållet i word of mouth på mottagarens inställning till det omtalade företaget
We investigate the effects of various types of word-of-mouth (WOM) messages on consumer bahavior. The message is varied along two dimensions where one is valence and the other is whether or not it contains an explicit call for certain behavior or attitude change. We use an experiment in the form of a web-based survey. Five different scenarios were designed to represent neutral, positive, and negative WOM. The latter two came in two different versions - one with a recommendation and one without.

Hälsoprofilbedömning - en metod för förändring av levnadsvanor?
It`s important that every person take responsebly for her own lifestyle to promote health.Today the individuel often knows the consequense of a certain lifestyle, but she doesn`t know how to change the negative behavior. Health profile assesment (HPA) is a method where you through conversation transfer knowledge and awarness about the member. The healthprofiler also motivate to a healthier lifestyle. Our purpose with this studie was to examine how individuels effects of a health profile assesment also illuminate which part of the health profile assesment the individuels have noticed and which way of living they change. To answer our purpose we used a quantitative transverse study in the way ofquestionnairexamination as we shared to a selection (n=193) on different companies inOstergotland and Scania.
Oralt intag av grönt te och dess effekt på uppkomsten av UV-inducerad hudrodnad, erythema solare ? En systematisk litteraturöversikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Oral intake of green tea and its effect on the appearance of UV-induced erythema, erythema solare ? A systematic literature reviewAuthors: Ernita Antoni Mulliqi and Pernilla GustafssonSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietetics programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: UV irradiation of the skin can cause erythema, clinically called erythema solare. The condition can exert pain as well as discomfort and may in the long term lead to negative effects including skin cancer. Green tea contains catechins which are substances with anti-inflammatory effect that may have positive effects on the skin. The intake of green tea is believed to have a protective effect against UV irradiation, since green tea extracts in lotions in previous studies have shown to increase the skin tolerance level against UV irradiation.Objective: To examine the scientific basis and determine whether an oral intake of green tea has a protective effect against UV-induced erythema.Search strategy: Searches in the scientific databases PubMed and Scopus were made to find suitable articles.
Resursskola, berättigad skolform eller tvivelaktig placering? : -en studie ur elevperspektiv.
The purpose of this report is to investigate teachers views of whether pupils with Asperger Syndrome, autistic symptoms or ADHD shall go in ordinary classes or special groups. The study tells you about what difficulties these pupils often have, what adjustments they need in their schoolsituation and the positive and negative effects of joining a special group.A teacher for special needs, two teachers in special groups and two teachers in ordinary classes have been intervjued and earlier made researches have been studied.The conclusions of this study are that the decision of whether a pupil shall go in a normal class or a special group must be made individually. Most pupils who are capable to profit from the training in a normal class and pass their examination, shall go in a normal class. The greater part of the recommended adjustments are possible to do in a normal class. But it requires more resourses and teachers with better knowledges about theese handicaps..
Malmö - möten och mångfald? En studie av bostadssegregationen i Malmö med fokus på Västra Innerstaden och Limhamn-Bunkeflo
This is a study about residential segregation in Malmö. The aim is to highlight the segregation that is taking place in the city as a whole. I therefore focus on two residential areas in Malmö which are not often mentioned when speaking about segregation; Västra Innerstaden and Limhamn-Bunkeflo. I present different theories on housing segregation and discuss them in relation to these specific residential areas. I investigate how the socio-economic and ethnic characteristics of the inhabitants in these residential areas are connected to Malmö being a segregated city.
