Att gestalta en socialt hållbar begravningsplats
This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.
Handelshinder som policy. Exportkontrollens effektivitet och påverkan på Sveriges handel med krigsmateriel 1984-2010 kopplat till policyutveckling.
The purpose of this thesis is to analyze the regulatory power, efficiency and impact of export control on Swedish arms export from the 1980s onwards, linked to the delegation of authority of permit license to the Inspectorate of Strategic Products in 1997. An increase in the administrative sector, based on a collective decision making process and established criteria and guidelines, aimed to strengthen the control of arms export to non-democratic and problematic states. In short, the aim of the study is to investigate and analyze whether there was a decrease in the arms export to problematic states or not. On one hand, it is reasonable to assume that the introduction of the new regulation entailed a more strict arms export policy. However, previous research has showed that regulations are sometimes not effective since incentives to breach these may be present.The study begins by examining the Swedish case and situation in terms of arms manufacturing and export, as well as the delegation of authority and legislation applied to the field over time.
Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer
Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.
Mest för syns skull? : en studie av effekten på Sveriges utlandsexport av statsbesök
Detta är en undersökning av Sveriges statsbesöks effekt på Sveriges export. För att mäta effekten använder jag mig av en empirisk modell, den så kallade handelsgravitationsmodellen. Jag finner att det är svårt att hitta starka och statistiskt signifikanta bevis på att Sveriges statsbesök har en positiv effekt på exporten. När man isolerar för statsbesök i Europa utanför Norden finner jag till och med tecken på att de kan ha en negativ effekt. Jag har även jämfört effekten av Sveriges statsbesök med effekten av Storbritanniens och funnit att Sverige har en generellt lägre effekt än Storbritannien, oavsett vilken modell som används..
Kloridutlakning från flygaska : möjligheten till en lokal hantering
In Sweden, there are limits to how much leachable substances waste must contain in order to be deposited as hazardous waste. Fly ash from waste incineration often end up over the limit, mainly due to the chloride content. Fly ash is therefore often deposited abroad. The purpose of this study was to investigate the possibility to handle fly ash locally. To clarify how the law is applied, environmental reports and permit documents from ten waste sites with permission to deposit fly ash were studied.
Solenergi : en lönsam investering för ett lantbruk?
A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.
Att göra affärer i Kina - rättsligt skydd i lagen och i verkligheten
This thesis looks at the difference between the legal protection in law and the legal protection in reality when a small company working with international trade comes in contact with seller's breach of contract. The thesis uses a case taken from a company with over 30 years experience trading with China and looks at the legal protection available along with the different possibilities of dispute resolution available to a company and then looks at the reasons why this legal protection never becomes a reality and the thesis also analyses some possible reasons for this gap between law in the books and law in reality..
Hållbarhetsaspekter på tillvaratagande av spillvärme i borrhålslager- ur ett företags- och samhällsperspektiv
The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.
Odlingens och lagringens inverkan på utsädes grobarhet :
At seed-growing the aim is to produce a commodity with high germination capacity, good soundness
and purity, and also slight admixture of seeds from other species. The capacity of germination and the
vigour of the seeds may become impaired in consequence of mechanical damage, infection of diseases,
growth of mould, attacks of vermin, high drying temperature, secret germination, sprouting in the ears
etc. The germ belongs to the outer and most unprotected parts of the seed, and consequently this is
much exposed. Even quite sound seeds can instantaneously have low capability of germination. It can
be due to the fact that the seeds are in rest of germination, i.e.
Blankning i rättslig belysning
Shortselling and loan of shares are becoming a common complement to"traditional"trade in shares. To be able to lend shares, it is necessary to reregister the shares so that the shortseller is competent to sell these shares further. In a legal sense, the proprietorship of the shares has changed hands, though it is not obvious for those involved to see what happens to the prorietorship. The obscurity is principally whether a complete changeover of the proprietorship is made between those concerned. This essay makes clear which legal consequences loan of shares and shortselling get concerning the proprietorship, and how a conflict between the lender and the third party should be solved if the shortseller becomes bankrupt.
Gynnar eller motverkar kommunerna kostnadseffektiv miljöstyrning : en studie av kommunala taxor och avgifter
Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals.
The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.
Bakteriereduktion i diskmaskiner : Studie av olika metoder för att reducera bakterier
Bacteria are a problem that occurs naturally in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since this causes unnecessary energy waste and emissions of chemicals in the washwater. To solve the problem in a more environmentally-friendly way by directly attacking the bacteria with an appropriate bacterialreductionmethod can therefore be an attractive feature in a dishwasher. There are many different ways to treat surfaces that have been exposed to the bacteria. Some high-profile methods are UV-radiation, microwaves and oxidant (ozone) that all three have had success in reducing bacteria in different contexts.
Alternativ utformning av WTC i Växjö
Stationsområdet i Växjö genomgår omfattande förändringar, där bland annat planer för ett WTC finns. Ett förslag på nämnda byggnad har tagits fram, men det fick kritik. Man menade att det inte stämde in i stadsbilden. Vårt syfte och mål har därför varit att ta fram alternativa förslag på utformning av ett WTC, med hänsyn till kritiken. Vår metod bestod i att sätta oss in befintliga detaljplaner och utföra eget skissningsarbete.
Liv och rörelse på nya Kungsgatan : Ett arbete om framkomligheten på Kungsgatan i Eskilstuna
This report is about how accessibility in Eskilstuna's central trade street Kungsgatan can be improved, based on my background as spatial configuration designer, and by Eskilstuna's residents' opinions. In this report I explain what methods I have used, and how I attained my results. The goal of this project was to create ideal accessibility in the central part of Kungsgatan in Eskilstuna. Since Fristadstorget was rebuilt, and since the city is growing in terms of housing and residents, accessibility will in the near future be even more limited for visitors than it is today. My design proposal is designed based on street conditions, residents' opinions and Eskilstuna's existing ideas..
Vilka faktorer f?rklarar kapitalstrukturen och hur deras p?verkan f?r?ndrats under Covid-19? En kvantitativ studie av 214 bolag listade p? Stockholmsb?rsen
Studien visar att flera faktorer har en signifikant p?verkan p? kapitalstrukturen f?r de unders?kta f?retagen, b?de f?re och under Covid-19 pandemin. Analysen identifierade att l?nsamhet, f?retagsstorlek, tillv?xt, tillg?ngsstruktur, likviditet och risk alla spelade en viktig roll i hur f?retag strukturerade sin finansiering. L?nsamhet visade ett negativt samband med skulds?ttning, vilket indikerar att l?nsamma f?retag f?redrar att anv?nda interna medel i st?llet f?r att ?ka sina skulder.
