Systemlösningar för plus- eller passivhus : En studie med syftet att lösa energibehovet för ett specifikt hus.

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

Företaget i varseltider - Påverkan på dess effektivitet och produktivitet

Syftet med studien är att undersöka varsels effekter för företags effektivitet och produktivitet under lågkonjunktur. Vår studie bygger på intervjuer med både chefer och anställda från företaget Water Jet Sweden AB. Studiens resultat är att personal påverkas av företags beslut om varsel om uppsägning genom att arbeta mindre effektivt. Detta är så för att varslet sänker arbetsmotivationen och tryggheten vilket gör att personalen underpresterar, detta påverkar hela företaget negativt..

Analytikers värdering av Goodwill -En kvalitativ studie av goodwillens betydelse vid företagsvärdering

Time has passed since the new standards regarding goodwill were introduced. Duringthe period that occurred pre the financial crisis several companies managed to creategreat goodwill assets on their balance sheet. These assets were highlighted during thefinancial crisis and the aim of this study is to evaluate analysts contemporaryconsideration of these assets. The study will be of interest due to the fact that we nowfind ourselves in-between periods, post financial crisis and pre euro crisis. Ourempirical study has been carried out by interviewing analysts covering IT-companiestraded on the Swedish stock exchange.Our analysts were chosen with consideration to the fact that they were coveringcompanies where acquisitions are common.

Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Vermicompost for reduction of vegetable waste - and a possible means to produce fish feed in aquaponic systems?

Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water. The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission. The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed. Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed. As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting). The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture. Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied with 0.8 L per week.

"Herregud, det är ju en revolution". En undersökning av flerspråkigheten på Europaparlamentets intranät och de positiva och negativa effekter som uppstår i samband med dess flerspråkighet

This is a thesis on the Intranet use in the European Parliament. We investigated the use from a multilingual point of view, but also from a communication perspective. What we wanted to know was how a multilingual group, with presumably different computer skills, in the organisation handle the Intranet information. What are the positive and negative effects of a multilingual information exchange over an Intranet? To find out, we sent a questionnaire as an e-mail attachment to all members of a chosen committee and their assistants.

Vattentäta och ?andande? textilier

Rapporten innefattar en jämförande studie mellan olika typer av membran och beläggningar.Främst sker en jämförelse mellan materialens förmåga att andas. Vattentäthet testas på nyamaterial och efter olika sorters nötning så som martindale, flexing och tvätt för att få en ökadförståelse för materialen. Verktyget som används i studien för att mätaånggenomsläppligheten är hudmodellen. Resultatet presenteras med ett Ret-värde vilket är enförkortning på Evaporative resistance of a textile. Metoden används för att på ett bra sättsimulera hur huden svettas.Projektet har utförts på Swerea IVF som är ett forskningsinstitut beläget i Mölndal.Hudmodellen är en av de senaste stora investeringarna på Swereas textil och plast avdelning.Resultatet av studien visar att laminat andas bättre än beläggningar, dock har bärarmaterialetstor inverkan på resultaten.

Fågel fisk eller mittemellan?

The project is a thesis which intends to strengthen the form language and increase the user friendliness of an International Moth. This is a single handed dinghy with only one sail. It sails on two hydrofoils and receives a very high speed compared to its size, and are therefore often referred to as ?the Formula One on water ?. The result is a new concept where the aerodynamic forces have been used to stabilize the boat and relieve the hydrofoils.

Windows, RedHat och IPv6 - ett test!

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

Barns föreställningar om de första djuren som utvecklades på jorden

No previous studies have been conducted on elementary school in Sweden about children`s thoughts about the first animals on earth. The work takes up the children`s ideas of the first animals and the difference between girls and boys knowledge. The purpose of this work was to determine if student`s views are consistent with the science know today. In the interview, five girls and five boys participated. Mankind is asking where it all began, today we know that the first life arose for 4 billion years ago and it was from the water.

Utveckling av en LC-MS-metod för analys av gamma-hydroxibutyrat, gamma-butyrolakton, 1,4-butandiol, amfetamin och metadon

In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Internationella skillnader i uppfyllelsegraden av IFRS upplysningskrav för goodwill : En jämförelse mellan Sverige och Storbritannien

Since 2005 the International Accounting Standards Board (IASB) has prescribed a mandatory requirement that all ?Publicly Consolidated Entities? abide by the ?International Financial Reporting Standards? (IFRS). However, due to a difference in institutional elements, between countries, differences in financial reporting are still possible. This essay aims to identify such differences between Swedish and British companies in their adaptation of the IFRS, specifically differences in; ?Disclosure Requirements for Goodwill? specified in ?IAS 36 p 134?.

Den reviderade Kodens effekt på informationsgivningen i svenska bolags årsredovisningar

As of 1 July 2008 the revised Swedish Code of Corporate Governance applies to all Swedish companies whose shares are traded on a regulated market in Sweden. The purpose of this thesis is to investigate whether the introduction of the revised Code has affected the disclosure practice among Swedish companies. We investigate a sample of 43 small and mid cap companies listed on the OMXS Exchange that has previously not been covered by the regulation. We develop a disclosure index, measuring the disclosure level in annual reports before and after the introduction of the Code. The results from the study show that disclosure level has not increased after the introduction of the Code.

VäxtVäktare

Most people have been forced to throw away a pot-plant after its death. There are many reasons to the death of a plant, but mainly it?s because its owner forgets it, and therefore fails to water it. The purpose of this project is therefore to develop a product which can prevent this from happening, while the product has to have a low manufacturing cost to be able to compete whit other, similar, products on the market. During the project, a benchmarking has been done to give a clear picture of what the product has to compete with. The directives there are for CE-marking, and which of these who concerns the product has also been looked up.

Mail Exchange Protocol (MEP): Ett utkast till nytt protokoll för elektronisk post

SMTP, the current protocol for sending electronic mail (e-mail) over the Internet, has for many years suffered from several problems and limitations. When it was designed, well over twenty years ago, the requirements for e-mail were very different from those of today. A message was a text message in English, and both user and machine were explicitly named in the address. The protocol was not designed to transfer other types of messages, and no mechanism was included to verify the identity of the sender.In order to solve these shortcomings, a new e-mail protocol needs to be defined. This report specifies a basis for what such a protocol may look like.
