För många fattiga länder, främst i Afrika, har det blivit uppenbart att skuldbördan har utvecklats till en skuldfälla som är mer eller mindre omöjlig att ta sig ur. 1996 presenterade Internationella Valutafonden (IMF) och Världsbanken HIPC-initiativet; Highly Indebted Poor Countries, som är en strategi för hur skuldbördan för världens fattigaste länder skulle kunna skrivas ner till en mer hanterbar nivå. Initiativet kan sägas ha vuxit fram ur den kritik som IMF och Världsbanken har fått för tidigare skuldlättnadsstrategier. Samtidigt presenterades en strategi för fattigdomsbekämpning; eng. Poverty Reduction Strategy (PRS).

Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.

Energy consumption is at present a major political issue, and numerous projects that comprise many nations are currently in process to increase energy efficiency and bring down energy dependency. As a member state of the EU, Sweden now faces the challenge of implementing substantial energy-saving measures until the year 2016. One of these measures is the project ?Green Islands? financed by the EU that intend on creating sustainable islands in areas around the Baltic Sea. The Archipelago Foundation leads the project that concerns the Stockholm archipelago, where focus has been placed upon decreasing energy usage in businesses and services on Utö among other islands.

Sahlgrenska Academyat University of GothenburgDepartment of internal medicine and clinical nutritionAbstractTitle: Can exclusive enteral nutrition replace steroid treatment in pediatric Morbus Crohn?Author: Hanna Rymark Lehnér and Josephine PetterssonSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012Background: Morbus Crohn is a chronic inflammatory bowel disease which periodically causes great suffering for the patient. There is solid scientific evidence that treatment with steroids effectively induces and preserves remission. However, side effects are many and a great risk for stunted growth and skeletal development exists in children. A widespread view is that exclusive enteral nutrition is as effective as steroids in pediatric Crohn´s.

This final thesis is performed on commission of Hargs Bruk Ltd. Hargs Bruk manages one of Sweden?s largest privately owned forests. A main part of the managed forest is situated in Roslagen in eastern Uppland. Since 1934 felling calculations have been performed within the estate every tenth year.

To investigate the possibilities for effective soil tillage, that could imply lower costs, lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006. The experiment contained two treatments that were repeated three times and were carried out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the other. The experiment was conducted according to the guidelines of organic growing and seedbed preparation was done the same way in the two treatments. The pigs, three groups of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform an even tillage by strip-grazing, i.e.

I den tillverkande industrin ställer idag kunder krav på korta leveranstider samtidigt som de tillverkande företagen ser tid som en begränsad resurs. Detta innebär att företag tvingas fokusera på att reducera ledtiden och däribland produktionsledtiden. Vid tillverkning av kundanpassade produkter finns inte möjligheten att hålla lager för att snabbt kunna besvara kunders efterfrågan och därför måste dessa företag sträva efter att effektivisera sina processer för att reducera ledtiden.Syftet med detta examensarbete är att undersöka hur ledtiden kan reduceras i ett produktionssystem för kundanpassade produkter. Två frågeställningar har upprättats för att uppfylla syftet:1. Vilka möjliga orsaker finns till långa ledtider i ett produktionssystem som tillverkar kundanpassade produkter?2.

During the past decade environmental challenges have been intensified and given increased attention. This implies that businesses in all sectors strategically need to manage these challenges. The service sector is often considered as a sector with a low environmental impact if the direct environmental aspects are assessed. Still, it has been argued that the environmental impact that the sector gives rise to can create severe indirect environmental impacts. The products and services that are produced by this sector have a relatively limited use of physical resources which may make the environmental impact challenging to visualize. Banks belong to the service sector and it is partly banks that make the development of societies possible.

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

The purpose of this thesis was to analyze conception and foaling results of Swedish warmblood and Standardbred trotters using breeding statistics during the years 2000-2006. Key issues in this thesis were: Have the conception and foaling results of stallions changed during the period 2000-2006? What is the effect of the use of various breeding methods? Is testicle size correlated with conception and foaling results? How important are age, breed and level of inbreeding of the stallion for conception and foaling results? Breeding statistics were available for 537 Swedish Warmblood stallions and 305 Standardbred trotter stallions. To be included in the analyses, a stallion must have mated at least ten mares in total over the period 2000-2006. This criterion was met by 313 Swedish Warmblood stallions and 272 Standardbred trotter stallions.

Fragmentation and Reduction of forest area is a threat for many forest species and their habitat. Deficiencies in forest quality, such as lack of dead wood and old trees, are one explanation of the threat. The most important action to prevent the continued loss of forest types is to protect forest, but also to restore and to create areas that not previously had high nature values. Hence one of the key strategic roles for Fritid- och Naturkontoret, Uppsala municipality, is to monitor biodiversity in the context of urban planning. The majority of the Uppsala municipality residents live in urban areas and most of them spend some of their spare time in natural areas in cities and their immediate surroundings. Exploitation in and around Uppsala is high, but it is important that there is enough nature close to houses to meet the residents? needs of recreation.

The purpose of this thesis is to investigate the degree of influence of holes in the web of steel beams with long spanson weakening of their bearing capacity. Making holes in the web of the beam generally reduces the bearing capacity of the beam. However, it might be necessary seen from both an architectural perspective as well as from a building services perspective by creating an opportunity for building installations.The objective of this thesis is to examine how much an I-beam can be weakened without sacrificing safety and functionality. The investigation has been done by using Finite Element Method through commercial software.The regulation for structural design of building structures in Sweden used to be specified in the document known as BKR. But this was replaced by the European norm Eurocode back in May 2011.

Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

By using pollen analysis, 14C-dating and historical sources, I studied the history of vegetation and land use at an abandoned forest settlement near the Lade summer farms in the parish of Mora, Dalama. The aim of this paper is to investigate the agricultural establishment and development, the effects of this on forest vegetation, and the origin and development of summer farming. The analysis of pollen in a peat core revealed that a settlement was established at Lade around 1000 AD. Cereal cultivation, hay-making on the mire and extensive forest grazing were intro-duced as a complete agricultural system. Pollen analysis and the presence of ancient fields suggests that cultivation took place on permanent fields. Barley was the main crop, but rye and hops/hemp were also grown at the settlement.

Abstract The global average temperature has increased by 0,74°C over the last 100 years. Most probably, the explanation is due to increasing use of fossil fuels and the agricultural expansion of land use. The new life stile of mankind leads to increasing concentrations of greenhouse gases in the atmosphere. Food consumption contributes with approximately a quarter of the total greenhouse gas emission per person and year, why it is an important task to reduce these. The aim of this work is to quantify energy use and greenhouse gas emissions for (Swedish) herbs produced in Swedish greenhouses. The study is based on a LCA (Life Cycle Assessment) and collected data from participating companies producing herbs in pots.
