Samband mellan luftföroreningar och klimatfaktorer - en statistisk unersökning
That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.
Möte i månsken : ett belysningsförslag för Fyristorg
The object of the thesis is to propose a new lighting plan
for the square Fyristorg in Uppsala, and to describe the
process which have led to it.
It all started when I choosed the place together with the
municipality of Uppsala.
I have been doing research and analyzed how the place
and it´s existing lighting works both during different times
of the day and also in the evening.
After researching the place and it´s existing lighting I´ve
decided to put up the following goals fot the new lighting
design.
1. The general light level of the place shall be experienced
as higher than today.
2. The light level of the place shall be adapted to the light
levels of surrounding places.
3. The lighting shall be free from glare.
4. The lighting shall be adapted to people passing by.
5.The lighting shall be adapted to the surrounding
architecture.

Omklädningsrummens psykiska och fysiska miljö : Niondeklassares upplevelser av miljön, trygghet och kränkningar i omklädningsrummen
Several studies has identified the locker room experience as a potential deterrent for participation in physical education. Both psychological and physical issues arise due to several factors. Psychological issues include different kinds of verbal and physical violations, comparisons between pupils, feeling of vulnerability along with a stressful schedule. The physical environment can contribute to negative experience for pupils in terms of filthy premises and cold showers. These factors may contribute to higher absentee rates in physical education.
Reading the Common Foreign and Security Policy of the European Union in terms of the issue of Terrorism : An analysis on the evolution of the CFSP of the EU under the issue of Terrorism
In the post Cold-War era, world politics was transforming itself through its emerging complex issues such as terrorism and influential and interdependent actors such as the European Union. In this new era, the European Union was developing its Common Foreign and Security Policy pillar both to present a coherent and unified EU policy and to prove its political potent in order to become an influential actor on world politics. On the other side, security environment was also transforming its content through emerging actors and issues. As one of the most prominent actors of the world politics, the EU was influenced by the transformation of security environment, whose economic ?soft power? proved necessary but insufficient for being a global power in this emerging security environment.
Utvärdering av möjligheten att tillvarata energi ur processvatten : En undersökning gjort vid Olofsfors AB på uppdrag av UMIA AB.
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Majs till mogen skörd :
Corn is an important food and feed crop in the world, in Sweden it?s up till now grown
on limited acreages mainly for silage. But I think it can get more important if you can
grow it also for grain, because it?s a good animal feed for example, for life stock-, pigsand
poultry. On of corns advantage is that it can produce the same amount of dry matter
as for example wheat, barley and rise but with 25% less water.
I will examine if it possible to grow corn for grain production in the south of Sweden.
Vindkraft eller kärnkraft - En jämförelse
The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).
Hot, våld och trakasserier : En studie om handlingsutrymme, politiska ledare och demokrati
Studies have shown that politicians are significantly more likely to become victims of violent crime than other citizens in Sweden. In fact increasing political rank and engagement are directly proportionate to increased risk for violence. Threat towards politicians is not only dangerous to the individuals involved but also to the democratic system as a whole.Political scientists the world over have done a lot of research on democracy, but I have been unable to find a single method or theory that examines how violence, threat and harassment affect political leaders and democratic systems.The aim of this study is to expand the existing model made by Tommy Möller, professor in political science. In his model he presents 11 factors that affect political leaders ability to act. My aim is to develop his model by adding a 12 th factor ?violence, threat and harassment?.
Projektering av småhus med solvärme som huvudkälla
In this report a study has been done regarding different heating systems on which are the mostcomprehensive with solar heating systems. The report has also been focusing if solar power can beused as a primary heating source for supplying more than 50 % of the buildings total heatingproduction. The University of Dalarna constructed a demo-house for this purpose and according tocalculations the total solar usage is more than 50 %. This house has been made for referenceregarding the design of the heating system of property 5:37.Further studies have been made to compare different heating systems that are compatible with asolar system, where the compared systems purpose is to be independent of direct using electricity. Asystem of this design is regarded as sustainable according to environmental as economic issues.
Incidenter på svenskt sjöterritorium : En analys av de åtgärder som vidtagits vid incidenter orsakade av Öst- respektive Västblocken under 1960-talet
Sweden has long been nonaligned in peace with the aim to remain neutral in the event of an outbreak of war. Building confidence for this neutrality was important for Sweden during the Cold War. This placed high demands on the Swedish Navy to detect and repel violations of Swedish territorial waters. The archives, which contain the secret reports on the violations that occurred during the 1960s, have recently been opened up.The purpose of this essay is to study how the incidents that took place in Swedish territorial waters in the 1960s were managed and to examine if the handling of them was different depending on whether they were caused by the east or west side. Furthermore, the aim is also to try to categorize and interpret these measures from the two pairs of concepts of deterrence and reassurance and integration and screening.In making it possible to answer the questions, all the reports - 66 altogether - which refers to the incidents which occurred during the years 1962 through 1969, have been studied.
Utveckling av provmetodik för HVAC på lastbil : Klimatprovning i klimatvindtunneln CD7
The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.
?I can feel cold in a way...? Sjuksköterskors upplevelser av att vårda patienter som avsiktligt skadar sig själva
Antalet patienter som vårdas på sjukhus i Sverige på grund av en avsiktlig självdestruktiv handling, har ökat under de senaste tio åren. Patienternas behov av vård kan variera och deras problem kan vara svåra att definiera i form sjukdomsdiagnoser. Förutsättningar för sjuksköterskan att upprätthålla en god vårdrelation kan påverkas och svårigheten att bedöma patienternas behov kan ge upphov till vårdlidande. Uppsatsens syfte är att beskriva sjuksköterskans upplevelser av att möta och vårda patienter som avsiktligt skadar sig själva. Materialet för studien utgörs av sju kvalitativa artiklar som bygger på intervjuer av sjuksköterskor, där upplevelser av att vårda den här patientgruppen beskrivs.

Plants as rhubarb and ginseng were used in China long time ago. The Egyptians had knowledge of herbal medicine such as aloe, myrrh and henbane, 1550 BC. The father of medicine Hippocrates used a large number of herbal medicines, and had many theories on the subject.Different parts of the plant can be used to extract the active ingredients.
Solenergi En del i ett långsiktigt, hållbart byggande
The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.
Varbergs Societetspark 1856 - 2008 : en promenadparks förvandling
The Societety Park (Societetsparken) of Varberg here in Sweden, established in the year 1883 (1856), is one of the most famous parks in Varberg. Today it is, more or less, only used as a park that you will walk through in the wintertime, under the summer season though, the park starts blooming and then it is used for public music and singalong evenings. Earlier it was an old health resort park with its fine old traditions.The Societetsparken was a private owned park until 1902 when the town purchased it. On this plot there was already a smaller park and it was established as early as in 1856. It was called Badhusparken (The Public Bath Park) and it belonged to the hot- and cold-bathhouses, and these baths were very well frequented.
