Syns inte - Finns inte? En kvalitativ studie om unga som valt att ej dricka alkohol.

The purpose of this study was to examine how young people who have chosen not to drink alcohol experience themselves and their surroundings. The aim was to find out what role temperance plays in their perceived identity. I also wanted to find out how they experienced the views of them, temperance and the temperance movement in their surroundings. Finally, I was interested in the question about alcohol, witch significance they believed it had for them and their surroundings. As theoretical ground, I used Howars S.

Development of green space in Dar es Salaam, Tanzania

In Dar es Salaam, as in many cities in developing countries, green areas are decreasing due to the fact that the growth of buildings, infrastructure and services has become a priority. As the population increases more buildings and infrastructure are needed and much of the building activity takes the form of uncontrolled settlements, which encroaches the public green space. Dar es Salaam has approximately three million inhabitants, of which about 70 percent are living in informal settlements. The aim with this study is to make a design proposal for a park and recreation area where the Msimbazi river basin in the centre of Dar es Salaam is today. The basin consist of a few playing fields, footpaths and some urban farming, but apart from this it mostly consists of unused grasslands, swamps and forests. Because it is an unsafe place and badly connected to the rest of the city infrastructure, it has become a barrier. The annual flood combined with the constant still shallow water creates a good breading ground for malaria mosquitoes.

Analys av off-design prestanda för ett absorptionskylsystem

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

Taket och botten: tre amerikanska remakes av japanska förlagor

Det kommer konstant ut amerikanska nyinspelningar av andra länders filmer. Vad är det som skapar behovet av nyinspelningar? Vi har analyserat och jämfört tre japanska skräckfilmer med amerikanska nyfilmatiseringar (s.k. ?remakes?) för att försöka förstå vad det finns för kulturella särdrag i respektive länders gestaltning av filmberättartekniska konventioner av rum och tid och skillnader i kunskapsnivå om filmens händelser mellan protagonist och åskådare..

Växthusvävens fukttransmission ? Hur struktur och materialval påverkar växthusvävens fuktgenomsläpplighet

Växthus används för att ge ett bättre odlingsklimat åt grödor och växter. För ytterligare förbättring av förhållandena används växthusvävar som exempelvis kan reglera temperatur, fuktighet och ljustillförsel. Väven som behandlas i denna rapport är en så kallad energiväv som främst har till uppgift att minska energiåtgången vid uppvärmning.När väven är fördragen nattetid, ökar luftfuktigheten då grödorna avger fukt dygnet runt. Fukten kan kondenseras mot energiväven, vilket gör att det bildas droppar på väven som kan falla ned på växtligheten. Den höga luftfuktigheten kan medföra svampsjukdomar och i övrigt också bidra till att tillväxten avstannar.

Varannan vatten - Ett rekommenderat sätt att dricka : en intervjustudie om unga vuxnas upplevelser av fenomenet

Högtider är i Skandinavien förknippade med alkohol och festligheter, detta är en del av vår kultur. Konsumtionstillfällena är få och oftast placerade vid veckoslutet, det är mer accepterat att vara full en fredagskväll är mer än en måndagsmorgon. Beslut från regeringen avser mål och insatser för bland annat användandet av alkohol samt att minska bruket av det. Att begränsa alkoholens negativa effekter har länge varit en viktig fråga för folkhälsan. I och med detta skapades kampanjen Varannan vatten, för att minska berusningsdrickandet i samhället.

Analys av energianvändningen i kvarteren Carolina och Jenny : en fallstudie

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

Stubblyftningens initiala effekt på emissioner av växthusgaser från en granmark i Småland :

In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead. This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.

Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Klimatförändringars påverkan på kulturmiljöer i Uppsala stad ur ett geovetenskapligt perspektiv

Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.

Rattfylleri : Varför kör alkoholister rattfulla?

This essay is about the consequences of alcohol and driving. The topic was chosen because of all the accidents that have taken place during the last couple of years, where the drivers have been under the influence of alcohol. A number of these accidents have had severe consequences, and in some cases the outcome has been deadly. The author has interviewed members of Länkarna; a non-profit organisation that helps people with alcohol related problems.The purpose of writing this essay was to find a reason why alcoholics drive while being intoxicated. Is there really a reason? It is important to look at this because a drunk driver is hazardous to himself and to other drivers.

Bastu-frigidarium,energieffektivt system för återhämtning

Sweden is considered to have one of the world's highest animal welfare standards in agriculture. Despite this, there are shortcomings in animal husbandry. One example is overcrowding, which is a way to increase stock size without making costly investments in the buildings. It can be carried out systematically to increase profitability or due to, for example uneven calving during the year. The European Commission criticizes the fact that stocking density is not controlled under Swedish welfare inspections.

Koldioxidavgång vid ekologisk odling på organogen jord

The background of this work is the media discussion about the effect of cultivation on peatsoils on greenhouse gas emissions. It has been argued that row sown and intensivelycultivated crops such as carrots are more likely to emit carbon dioxide than for example grassleys. The association KRAV (an association promoting organic farming) shall, from this yearadapt their environmental policy to be more climate smart and have asked the question if thecultivation of some crops is more climate smart than others? Carbon dioxide emissions fromsoil are due to degradation of organic material and the rate is controlled by microbial activity.The microbial activity is determined by a variety of factors such as temperature, soil organicmatter quality and water content. I have measured the carbon dioxide emission from fourdifferent crops at two different farms.

Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.
