Effekten av tillskott av CLA på kroppsvikt och andel kroppsfett hos överviktiga och feta

Sahlgrenska Academyat University of GothenburgDepartment Of Internal Medicine And Clinical NutritionAbstractTitle: The effect of CLA on body weight and body fat amongst overweight and obese.Author: Sierra De Goldsmith and Amanda EgebergSupervisor: Frode SlindeExaminer: Anna WinkvistProgram: Dietician study program 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 12, 2012Background: Overweight and obesity represents a global problem as it is accompanied by an accumulation of body fat which increases the risk of developing diseases such as diabetes type 2, insulin resistance, cardio vascular diseases and certain types of cancer. Moreover, the prevalence is increasing worldwide. Many consider it difficult to reach a normal weight using only methods such as changing dietary- and exercise habits, this creating a market for products that facilitate weight loss and loss of body fat. The supplement of conjugated linoleic acid (CLA) is such a product. In animal studies, CLA has demonstrated a reduction in both body fat and weight.

Nationell naturvård i en lokal kontext : En analys av ett nationalparksförslag i Södra Jämtlandsfjällen

Local participation in nature conservation has gained more attention over the last decades due to international conventions as well as local and national initiatives. This development can be seen as a reaction to a more expert oriented nature conservation characterized by centralized control and strict preservation of so called "original" nature. The overall objective of this thesis is to contribute to research on new forms of conservation where democracy and local participation is included. The case study focuses on the process of producing a pre-study for a suggested national park in southern Jämtland in the Swedish mountain region, and aims to investigate to what extent local participation was included. The pre-study was led by the Swedish Environmental Protection Agency (SEPA) and the County Administrative Board (CAB) in Jämtland.

Utlakning av tungmetaller från Skörby deponi

The purpose of this thesis has been to assess whether leaching from one particular Swedishlandfill site, Skörbytippen, is contributing to elevated levels of heavy metals in a ditch runningfrom the landfill site to the lake Mälaren in the communal region of Håbo kommun. Since theditch is stretching approximately five km downstream from the landfill site, in situ observationsand maps with known points of inflow was utilized to determine appropriate test points for thecollection of samples.Soil, water and sediment samples were collected and analyzed for content of organic material, pHand conductivity. Data on plant-available elements and total amounts of heavy metals wasacquired through ICP-analysis.The results show that the Skörby landfill is currently in the methane-forming anaerobedevelopment phase, which indicates that the concentration of free and complex-bound metals inthe leachate water should be low due to chemical binding with other landfill compounds. The pHof the sediment samples was generally one unit higher than the soil samples and some of themeasured data, such as pH and conductivity, show that an environmentally disturbing dischargeof some kind of strongly alkaline chemical(s) has been made from Benders? takpanneindustri inclose proximity to the landfill.

Ekologiska livsmedel i offentlig måltidsverksamhet

In our everyday life we are faced with many choices that have consequences on the environment. One of these is the food we choose to eat since food production has a big impact on the environment. In organic production the aim is to have a natural production process, where environmental impacts are minimized. By choosing organic food it is therefore possible to contribute to a better environment. A large number of meals are served every day in the public sector, which makes it an important player in the consumer sector that could make a major difference for the environment..

EU:s omställning till en hållbar jordbruksnäring

Cultivable land is a limited resource and agriculture contributes to some of the most serious environmental problems facing the planet like, global warming, eutrophication and loss of biodiversity. The specialized, industrial agriculture with monoculture and extensive input of external energy, commercial fertilizer, and chemical pesticides are all essentially unsustainable. An adaptation to other methods of production is necessary to preserve the environment for future generations. The aim of this study is to describe the factors that distinguish sustainable from unsustainable agriculture. The results will be used to examine if and how the European Union (EU) works in order to create a more sustainable agricultural industry and to analyze the preconditions for such development.

Kadmium i skånska vattendrag : en metodstudie i föroreningsmodellering

Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.

Barns utemiljöer i Hebron : gestaltningsverktyg för barnperspektiv implementerat på Al Ibrahimyye plats

This is a final thesis for the Master?s Programme in Landscape Architecture at the Faculty of Landscape Planning, Horticulture and Agricultural Science. The subject of the thesis is the outdoor environment of children in Hebron.The thesis aim is to investigate children?s basic needs and desires in their outdoor environment, and how these can be met in the design of a site in Hebron. A starting point for thesis is that children?s environments in the city should not be separated from city life in general, so that children and adults can meet in the city outdoor environment.The ongoing political conflict between Israel and Palestine is presented in the thesis by describing its consequences for the city of Hebron and the lives of its residents, with a particular focus on the everyday lives of Hebron children.

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.

Den kulturpolitiska forskningens intellektuella bas och inriktningar ? En författarcociteringsanalys av artiklar publicerade i International Journal of Cultural Policy 2002-2007

The aim of this thesis is to map the intellectual base, and identify the general research interests, of Cultural Policy studies. In addition to this the thesis also aims to trace the uses of theoretical and conceptual approaches within the identified research interests. This is done by analysing citations from 130 articles published in the leading scientific journal International Journal of Cultural Policy between the years 2002-2007 using the bibliometric method author cocitation analysis (ACA). The results of the ACA confirm the overall notion that the research field of cultural policy studies is an ambiguous one, even when it?s studied with a quantitative method specialised in uncovering hidden structures within a given field as ACA.

Lindehults handelstr?dg?rd: en fallstudie med fokus p? j?rnv?gens nytta f?r en ?kad marknad

This case study's aim was to strengthen the state of knowledge about how horticultural companies in Sweden used railway transports between 1900s and the 1950s. Economic theories and a micro-historical perspective have been used to analyze the collected source material, and to describe Lindehult's market garden. The investigation is based on document analyzes, qualitative interviews, archive studies and literature studies to evaluate the sources' information through a source pluralistic method. The work has been based on historical source material in the form of payment vouchers, giving an insight into how the company's products were transported by rail across Sweden. Sture Hjalmarsson's diary and interviews have described the case and events that affected the company internally.

Metoder för att beskriva kumulativa effekter med avseende på biologisk mångfald och vägar :

Cumulative effects are seldom treated in Swedish Environmental Impact Assessments (EIA). This report treats these questions and which procedures and methods that can be used when assessing cumulative effects in EIA. This report is a literature study where also a case study is a part. The case study shows how existing methods for cumulative effects can be used in practice. The report is concentrated on biology and treats cumulative effects on premises of biodiversity and roads. Cumulative effects include both direct and indirect effects.

Lgy11: en kontrollerande läroplan. Samtal med fyra gymnasielärare

The autumn of 2011, saw a new curriculum being put to use in Swedish schools, a curriculum whose purpose was to supply the Swedish schools with a larger national equivalence. This new curriculum was meant to counter the strong variations in grading that the ministry of education felt was a result of the Lpo94, the curriculum previous to lgy11's introduction.With the introduction of the new curriculum there followed some changes to the objectives and emphasis on content prepared by teachers in the subject of religious studies. As a result this also affected the teachers planning and execution of the course and its content. From the perspective of a teacher-to-be I hold a great interest concerning how lgy11 affected the religious teachers planning of their lessons and teachings. This essay is written with the hope of being able to determine how some of the now active teachers perceive that they have been affected by the curriculum in its structure of teaching and planning and the content of material.

Kvinnor utan klass? : en feministisk studie av kvinnor som klassresenärer

This essay is an in-depth, qualitative study concerned with questions about female ?class-travellers?. A class-traveller is a person who is born and raised in a particular social class but changes his/her social belonging through studies, marriage etc. In this study I have interviewed three female class-travellers, all of which have made their ?journey? through studies at the University of Lund.The study is an attempt to enrich the research-field of class-travelling by applying a feminist perspective, and by making women's voices about class-travelling heard.

Kapitalstruktur i fastighetsbranschen : En studie av svenska noterade fastighetsbolag 2005-2010

Recent studies made by Margaritis and Psillaki,have shown that a lower debt ratio and higher efficiency are correlated in their studies performed oncompanies in New Zeeland. Other researchers have been able to show a connection between other industries than the one used in our studies,among these are Titman and Wessler. These studies have been done with a great selection of companies in different industries and time periods. However most of these researchers have used traditional ratios and variables.This study aims to find and analyze connections between returns and lower debt ratios in real estate companies listed on the Stockholm stock exchange. Instead of the traditional debt-equity ratio we will construct our own taking long term debts and property assets.

Dom kallar det Lean? En studie om Lean i sjukvården och dess påverkan på den professionelle läkarens medicinska beslutsfattande

The purpose of this media scientific study is to contribute to a better understanding about how blind people?s empowerment and participation may affect their role in the digital society.Earlier international studies in this area have shown that blind people not only need more knowledge then the seeing population about the computer, but also about the technology behind their tools for using Internet. The results from these studies have also shown that Internet increases the blind people?s independents and that those who use Internet feel more involved in the society.A qualitative method was chosen to study the three most common categories from the earlier studies: knowledge of technology, empowerment and participation. Are there differences in the results compared to our study in Sweden 2014?Interviews with eight blind, experienced computer users have shown that knowledge of technology is essential for their use of Internet and that the Internet increases their empowerment and their participation.
