AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method:  Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine.  Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

In this thesis an energy analysis of ethanol production at the ethanol plant of Lantmännen Agroetanol in Norrköping has been performed. The ethanol plant has been studied in combination with Händelöverket, the combined heat and power plant which provides the ethanol process with steam. The purpose of this study was to determine the energy consumption for the whole production chain from grain to ethanol. The analysis has included the energy consumption for cultivation of grain, production of chemicals, the production chain for wood chips, the steam production and the ethanol plant. The grain and wood chips are both considered raw materials there for the energy content in these are not included as energy input in the system.

The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle perspective is applied.

Värmeböljorna blir allt vanligare i Sverige vilket kommer kosta sjukvården miljardbelopp. Hur kan denna trend motverkas? Träd kanske inte är hela lösningen på problemet, men är en hjälp på vägen. Det urbana landskapet har idag högre temperatur än omgivande landsbygd. Detta fenomen, den så kallade urbana värmeö-effekten, beror bland annat på att hårdgjorda ytor absorberar solenergi, antropogena källor utsöndrar värme, luftföroreningar fungerar som växthusgaser och bristen av nerkylande vegetation. Dessa faktorer bidrar till en ohållbar temperaturstigning. Kandidatarbetets mål har varit att ta reda på hur träd bidrar till en temperatursänkning inne i städerna och att identifiera urvalskriterier för att välja träd ur temperatursynpunkt som samtidigt fungerar i urbana miljöer.

Bakgrund: Under senare tid har mediedebatten fokuserats kring olika dieters påverkan på viktminskning och välbefinnande. De moderna dieterna har debatterats av läkare, forskare och myndigheter, då extrema lågkolhydratsdieter innehåller alltför mycket fett vilket vissa menar kan leda till framtida folksjukdomar. Syfte: Syftet var att undersöka ett begränsat antal dieters påverkan på viktminskning och välmående samt att belysa betydelsen av en helhetssyn på våra kostvanor. Metod: Denna litteraturstudie är baserad på fyra vetenskapliga artiklar som var relevanta och intressanta för syftet. Resultat: Samtliga av de artiklar som undersökte sambandet mellan olika dieter och vikt visade på en tydlig viktminskning hos alla deltagare.

AbstractAt a time when the discussion of feminism is hot in the media, in the schools and in the cottages so I have been interested in how feminist worlds order might look like and what are the roads there. There are plenty of barriers in the community, some of them you easily could influence.This essay problematize and define the problems behind the difficulties of reaching a feminist world order, but also the factors that are important to achieve this world order. How colonization that began several hundred years ago spread and secured the patriarchal society and its influence all the way to the society of today. But even more immediate factors, on how we ourselves are involved in shaping our society in terms of where we live, how we educate ourselves, and what jobs we choose. Status symbols in society as economics, profession and political influence are all to be reckoned with when it comes to influencing society.

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

Sometimes relatives have taken me on one side and told me they cannot bear it any more:"Isn't there something you can do to end it all?"More often requests for euthanasia have come from those who are ill. I remember visiting a man with lung cancer. He asked his wife to leave the room. As she closed the door he leaned over and grabbed my arm.

To be able to feel a sense of belonging, people need to have the possibility to take part of the information from the society. Hearing-impaired don?t have the same possibility as hearing people when they want to take part of the information, therefore they don?t get the same benefit. This contributes to a feeling of not belonging and a sense of limitation in different social occasions. Therefore the society needs to be accessible to everyone regardless disability.

AbstractProblem: This thesis was made by a commission from Svensk Logistikanalys AB (SLA). SLA is a relatively new firm who is working as a freight broker for firms that wants to lower their freight costs. SLA contacted Jönköpings international business school because they experienced a problem with too many firms, that had SLA?s concept introduced to them, but turned down their services. On the basis of this, following purpose of the report has been stated.Purpose: In this thesis we will study companies that have said no to the services of SLA.
