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..

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.

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.

Rapporten innefattar en jämförande studie mellan olika typer av membran och beläggningar.Främst sker en jämförelse mellan materialens förmåga att andas.

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.

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

The purpose of my report is to create an interest in hand caning and different caning patterns, both for professionals and interested laymen. My hope is that they will use my report as a guide and an inspiration, for techniques such as braiding a cane seat. I also discuss how better to preserve cane furniture and different ways in which to finish it. Weaving is easier than you might believe.Today many people discard old and inherited furniture with elements of hand caning because it is too costly to have it repaired by a professional. Some people also remove the cane work and replace it with upholstery and fabric.

Green public procurement (GPP) can be used as an instrument to reduce carbon dioxide emissions, and consideration of environmental aspects within public procurement is becoming more common in Sweden and internationally. Two product groups that have been pointed out as especially important are transports and electricity, where the opportunities for public purchasers to reduce emissions are relatively large. This paper studies GPP which aims at reducing emissions, primarily of carbon dioxide, through environmental requirements within these two product groups. A theoretical analysis of cost-effectiveness, transaction costs and effects on technological development is performed, followed by a closer study of how these aspects appear in practice within GPP. The results indicate that a cost-effective allocation of reductions between the two product groups is most likely to be attained if the main part of emission reduction is achieved through environmental requirements on electricity. The cost for emission reduction within transports is relatively high, especially for heavy transports. For transportation services, more generally focused requirements on emission reductions could probably give greater environmental gains, but the existence of transaction costs steer the environmental requirements towards more technology specific types.

The purpose of this study was to to examine what teachers think about visual art and how the learning process in this subject does look like. To answer these issues, I made interviews with five teachers of visual art from different schools, and I examined several examples of pupils? artworks. The stories of the teachers were analyzed in relation to governing documents and with assumptions from sociocultural theory, postmodernism and pedagogical - aesthetic research as theoretical point of view.By the qualitative interview method, the observations of the pupil?s artworks, and by the analysis of the interviews with the teachers, I have come to the conclusion that teachers think differently about art but they try to keep themselves in line with the national governing documents.

Speedledger is a company that is working to automate electronic accounting for businesses, organizations and associations.In the current situation bank data is sent from the users internet bank to Speedledger via a virtual printer driver. The driver transforms the web page into a PDF and sends it to a server for interpretation.The problem is that PDF is not created for this sort of data transfer and makes the interpretation of data is very problematic.The goal of the thesis is to study whether there is a possibility to develop a browser add-on that can retrieve information on the customer's banking page and send it on to Speedledgers server for interpretation. My task was to implement a add-on for one of the three major browsers Mozilla Firefox, Google Chrome or Microsoft Internet Explorer, and then study the possibility of implementing it to the other two by reading the documentation.What I concluded was that it is possible to implement for all the three browsers. However, the techniques will differ slightly when developing these add-ons.  .

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.

During the past twenty years the immigration to Sweden has changed significantly. Earlier immigration mainly focused at filling the vacancies in the Swedish industry, today immigrants primarily come to Sweden as Refugees. This change of immigration combined with the restructuring of the Swedish industrial sector has resulted in great a deterioration of the chances for immigrants to gain entry to the Swedish labor market.This study aims at examining how the cooperation between authorities in the municipal of Hörby in Sweden fosters integration. The study primarily examines how the cooperation between authorities in a integration project can contribute to a better integration to the labor market.Through a qualitative study, five persons who occupy important roles in the project have been interviewed. The results of these interviews have been complemented by internal documents as well as extern material to validate the results.The most important findings that have been revealed are the importance of language in the process of gaining entrance to the Swedish labor market.
