According to the theory of environmental Kuznets curve there is a relationship between carbon emissions and GDP. The relationship has an inverted U-shape. Carbon emissions rise initially and then decreases once a certain level of GDP is obtained.This essay interprets earlier studies in the field of environmental economics and uses public choice to seek answer on how the population acts on aggregate level. This essay analyses 115 countries in cross-sectional data. The analysis shows that there is a significant relationship between carbon dioxide emissions and GDP that is increasing at first and then decreases for a certain level of GDP.

AbstractThe aim: The aim of the study was to describe what women are most satisfied with in maternity care and if women´s childbirth experiences can be described by means of the QPP-I, who contains 32 statements related to maternity care. Design: The study is part of a national cross-sectional study which lasted for two weeks in Sweden in 2007. This paper analyzes one of the two questions with open answers, which reads: "What was the best with maternity care??. Results: The results showed that out of a total of 735 responses 717 could be placed in the existing instrument QPP-I.

Findus Sverige AB, referred to asFindus from now on, harvests peas during a period ofaround 50 days during the summer. The harvest generates about 30 000 tonnes of peas which gives around 40 000 pallets to distribute to the warehouses which Findus uses for final storage. Three hours after the peas are picked in the fields, they have to be frozen to keep their good taste and quality. Because of this the pallets are marked with a preliminary label with quality classification of the content. The Findus quality department then has one day to determine the correct quality of each pallet.

There is much research into the reasons why a temporary pain, in some individuals, becomes chronic. Many of the causal factors linked with pain also seems to coexist with social anxiety, public self-consciousness and, to some extent, private self-consciousness. The purpose of this study was to investigate and identify possible patterns of self-consciousness (private and public), social anxiety and pain. This was done by a cross-sectional study in which a questionnaire was distributed to students at Örebro University. A total of 302 completed questionnaires were received.

Forestry is an important industry in Sweden, with clear-cut as the most commonly used method for harvesting. Here the long-term impact of clear-cut on lake water quality (dissolved organic carbon (DOC), nitrogen, phosphorus and pH) has been investigated, based on 23 lakes sampled during autumn. Data for additional 15 lakes sampled for the Swedish monitoring program were also used. Lakes were classified as 5, 25, 40 and 60 year based on data of the forest age in the catchment, gathered from the Swedish national forest inventory. Clear-cut lakes were classified as 5 years (>20% of the catchment clear-cut during the last 10 years).

In this study I will analyze how men who buy sex interact with one another on two different Internet communities: ?Sekreterarakademin? and ?Flashback?. This analysis is carried out in an attempt to challenge the conventional image of the man who pays for sex.The aim is to examine the role of Internet forums for men who buy sexual services related to cross-border, both in terms of standard borders, gender boundaries, boundaries of sexuality and masculinity. I will also attempt to investigate what opportunities that are available to overrun different borders and how these opportunities affect the conditions of the various players. I will evaluate theories such as homosocialtet, hegemonic masculinity and normalization used by KAST (Köpare Av Sexuella Tjänster, the Swedish public support for clients of sexual services) and which are partially consolidated in studies published by KAST concerning issues related to internet based prostitution..

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

The purpose of this study was to examine how food managers of Östergötland County disucss around their possibilities of reaching the government´s orientation towards 25 per cent of the food - procured, prepared and cooked in the school meal - coming from certified organic production. The study was a cross-sectional study in wich a qualitative approach was used. The sample consisted six food managers in Östergötland. Data processing was done through a semantic content analysis.  The result showed that involvment and intrest were significant factors for the introduction of organic food in the school meal. The three municipalities with the highest percentage of organic food used the SMART - concept.

Simplicity, intimacy, freedom and one single threadcharacterize the knitting technique.In my project, I have studied ways of creating three-dimensional shape and structure using single threads and various knitting techniques. I applied my ideas in a collaboration with the singer Sofia Karlsson. The focus has been to design a portable object that can be used in pictures for the cover and promotion of her upcoming album.The material I studied, processed and used in creating the three-part object was linen. In the center stands a collar, that changes expression depending on how it is worn and which side is turned towards the outside. The collar interacts with a cylinder for her hands and a hairnet.

This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.

Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.

Detta arbete har sin utgångspunkt i ökad återvinning och minskning av sopberg. Ett exempel som vi har använt oss av i vår forskning är ett samarbete mellan Röda Korset och Kriminalvården. Varje år slängs 25 % av de textilier som välgörenhetsorganisationer får in och dessa sopberg skulle man kunna minska genom ökad återvinning. Kriminalvården har registrerat ett varumärke som heter Made in Jail, vilka tillverkar köksrelaterade produkter. Syftet med det här arbetet blev därför att utveckla idéer till hantverksprodukter som slukar mycket spill.Valet av metod blev kvalitativa intervjuer, som utfördes med tre personer med olika kopplingar till arbetet.

I Sverige fanns, mellan 1874 och 1994, ett förbud mot att bygga bostadshus med fler än två våningar i trästomme. Under denna tid försvann större delen av hantverks- och ingenjörskunnandet och man fick därför börja från början då förbudet hävdes. Byggandet gick till en början trögt, men tog fart i och med regeringens nationella träbyggnadsstrategi och utvecklandet av byggande med massivträ i början av 2000-talet. Limnologen i Växjö är ett bra exempel på hur långt fram Sverige ligger i utvecklingen, men det pekar också på områden inom tekniken som behöver förbättras.Den här uppsatsen behandlar översiktligt hur trähusbyggandet har sett ut i Sverige och beskriver sedan Limnologen med fokus på entreprenadform, stabilisering, brandskydd och akustik. Vidare beskrivs hur massivträtekniken har utvecklats och hur byggsystemet för massivträ har tagits fram..

Agricultural land could be polluted by radioactive substances after a fallout. We would then need information about the level of contamination to decide whether the crops could be utilized as food under these circumstances. In an experiment carried out during the 1990ies the retention of 134Cs in potato haulm and the transfer to the tubers were studied. The experiment was carried out during three consecutive years. The plants were cultivated in pots under field conditions and the artificial deposition was sprayed directly onto the potato haulm at different times during the growing season.

Calculations are an important part of planning around a construction project. From concept to completion of the project calculation is a tool to try to predict the actual cost. During the production stage in particular, deviations occur which makes the actual cost different from the calculations.This thesis is done in collaboration with JM Residential Stockholm. The study includes a cost follow-up in which a comparison was made between the calculated production cost and actual cost for the five projects. The aim of the study was to observe the most common reasons that a project deviates from the calculated production cost and then summing these causes in a number of categories.
