Karotenoider i tomater

The tomato is an important crop worldwide, and in recent years it has received great attention due to its rich content of carotenoids, which in studies indicate to have health benefiting properties. Many studies have been done in this area of research and in how to optimize the carotenoid content in tomatoes and tomato products. The objectives of this essay were to summarize present data in this field. The results were as follows:There are nine different carotenoids identified in tomatoes. Lycopene and ?-carotene are the ones that have been given the greatest attention.

Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

Mäns våld mot kvinnor ur ett teoretiskt perspektiv

The essay begins by asserting that the theoretical approaches of men?s violence against women are just as important to study as its extent. The purpose is therefore to analyse and compare two theoretical approaches which is done by a comparative text analysis of two texts written on the subject. The essay attempts to answer two questions; what the theoretical approaches are and how they can be understood in light of feminist theory.Previous research on men?s violence against women discuss especially three theoretical aspects.

Landsbygdsutveckling i Östergötland : - tre aktörsperspektiv och deras konsekvenser för landskapet

Rural development in Southeast Sweden- three different views and their consequences for the agrarian landscapeThis paper deals with the future for the rural areas of the southeast province of Östergötland, Sweden. The aim is to unveil, analyse and compare different views on rural development and their consequences for the agrarian landscape. Three views are considered, namely that of the different levels of Governments and their departments, that of the farmers and landowners and, finaly, that of the inhabitants of the rural areas.Differences in the views upon rural development is reflected in differences in the ways of thinking of landscapes. Is the open, and actively cultivated, landscape the ideal for all? Who is to decide what needs or ought to be done to achieve certain desired values and/or goals ? and who pays for it? The one thing that is, and should be, clear from the beginning is that all development, whether positive or negative in an area, bears consequences for the landscape.

VÄGTRAFIKBULLRETS INVERKAN PÅ UTFORMNINGEN AV BOSTADSBYGGNADER I STADSMILJÖ

The public interest in central living in today?s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today?s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software?s which calculates the levels of pollution, all this to investigate and improve the environment.

Effekten av mjölkkors rang på ?antistresshormonet? oxytocin, mjölkavkastning, mjölkflöden och besökstider i mjölkningsenheten i ett automatiskt mjölkningssystem :

The study was carried out at the Kungsängen Research Centre, Department of Animal Nutrition and Management, Swedish University of Agriculture Sciences, Uppsala. The technical development in dairy production has resulted in a housing system where feeding and milking is done automatically without human contact, a so called automatic milking system. The motives for utilising an automatic milking system, is to increase the animal welfare and to decrease the need for manual labour. However, the system does involve a change for the animals, among the effects is the deprival or the diminishment of a chance for synchronous behaviour and the animals have to agree among themselves in which order they use the feeding stations and the milking unit itself. How and if this affects the animals well-being and production is yet to be solved. A possible way to form an opinion on this, is to study the animals ranking order along with hormone profiles and production. The purpose of this work was to study the effect of low- vs.

Elevråd : Elevrådsarbete i två skolor

The purpose of this thesis is to determine whether the student councils at two schools really have the power to influence, or if it is a matter of mock democracy. I wanted to determine how the student councils work in reality. I conducted my investigation through personal and qualitative interviews with the board of the student council, a social studies teacher and the principle/school management at both schools. After the interviews I compared an analysed my findings. The results show that the two schools work very differently when it comes to studentdemocracy, and even have very different levels of ambition when it comes to the degree of influence that the student council should have at their respective schools.

Omgivningens betydelse för patienter med Alzheimers sjukdom : med inriktning på musik - En litteraturstudie

Background: Alzheimer?s disease belongs to the largest group of dementia and stands for the half of those 37 millions persons whom are affected of dementia in the entire world. Alzheimer?s disease affects the patients with changes on their behaviour. It is important as a nurse to prevent that the symptoms increase.

Resultatmanipulering: En studie av förekomsten av resultatmanipulering i svenska företag

The aim of this thesis is to examine the existence and prevalence of earnings management in Swedish companies. Theoretical frameworks often suggest that there are strong incentives to practice earnings management. The research area of earnings management has, to date, mainly focused on detecting earnings management. However, to our knowledge, no such studies have been conducted on Swedish companies. This thesis provides evidence of the existence and prevalence of earnings management in Swedish companies.

K3 eller K4 - Vad styr valet av redovisningsregelverk?

There will be changes in the accounting regulations in Sweden. Firms will be categorised as K1-K4 firms depending on the size of the company. There will be different levels of accounting in the four categories. Firms will always have the possibility to choose a more advanced accounting regulation than the one they are obligated to due to their size. The purpose of this dissertation is to investigate which factors that influence the management in K3 firms in the choice between the K3 and K4 regulation.

Beteendestudier och miljöberikning av gnagare

It is often challenging to create a new enrichment program for any animal. This is especially true with the additional challenge that I wanted to use only naturalistic enrichment, and I?m working with animals some of which are nocturnal. Even with a many hurdles, a little bit of enrichment can do a big difference and make a big difference in activity levels of the animals. Eskilstuna parkens zoo have a house called the MUSeum housing four kinds of rodents.

Xlight-Retro : En lampa för offentliga inomhusmiljöer

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

Hinder och framgångsfaktorer för personer med Aspergers syndrom : I steget från skola till arbete

The aim of this paper was to describe hindering and facilitating factors in the transition from upper secondary school and employment for a person with Asperger?s syndrome. In the process we used general systems theory and made semi-structured interviews with five persons in the network of institutions and associations working with the individual. Our findings showed that the hindering and facilitating factors were basically the same depending of the environmental adjustments. The interviews highlighted the following factors: the recent general unemployment rate in Sweden, selfawareness of the individual and the surrounding environment?s knowledge of the individual?s impairment in relation to Asperger?s syndrome.

Att förändra och förändras med tecken : En kvalitativ studie om uppleveser av teckenekonomi

The token economy program, which is a method for behaviour modification, has been used worldwide for different groups within different settings in order to vhange behaviour.Research has found the token economy program to be effective. However, research is limited to quantitative and experimental studies, and Swedish research in this field is brief. Nevertheless, the program is used in several institutions n Sweden. A qualitative study in Swedish settings could therefore be useful. The purpose of this paper is to examine the experiences of a token economy program using qualitative interviews.

GIS-program för ruttplanering. En studie av nyttjandet av GIS-program för ruttplanering inom tekniska förvaltningar bland kommunder i västra Sverige

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.
