Rock groundwater has always caused major problems when tunnelling. Water leaking into tunnels can cause large problems, not only on the construction itself but also on the environment. A continuous water leakage can lead to a declining water supply, and geotechnical problems can occur as subsidence in the ground. Therefore it is of great importance to predict the consequences that can appear in the surroundings due to a declining groundwater surface.The aim of the study was to investigate different methods for predicting leakage and changes in groundwater level due to tunnelling excavations in rock. This thesis was performed by comparing mathematical methods, actual groundwater changes and results from preliminary investigations.Investigations were made for three railway tunnels planned by Botniabanan AB.

Rabbits, Oryctolagos cuniculus, rapidly increases as pets. During the right circumstances, rabbits are friendly, social and playful. A rabbit who shows an abnormal behavior should always be examined by a veterinary, though there is almost always a medical problem. This essay is a result of a literature studie with the aim to find the prophylactic measures that may give pet rabbits a more healthy life. Rabbits have got a lot of common health problems, including dental, skin and gastrointestinal problems.

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

External forces have significant impact on organisations. This study analyzes the implications of one type of external forces in aid-focused NGOs through two qualitative case studies where it is investigated if Sida?s reporting requirements have the intended effects: learning and control using a theoretical framework where it is recognised that the requirements may also result in dysfunctional behaviour: decoupling and colonisation. The study shows that when the demands are the result of institutional pressure rather than an ambition to generate learning and control, the demands tend to be unrealistic and the NGOs therefore decouple the formal fulfilment of the demands from the actual activities. It is argued that a partnership, which incorporates trust and dialogue, is a prerequisite, not only for learning, but also control.

Swedish farmers have the possibility to be subsidized by EU rural development programme for grazing animals on pastures to promote the biodiversity of flora and fauna. The environmental remedy sometimes does not allow supplementary feed and at the same time the Swedish Animal Welfare Act and the Swedish Agricultural Board?s regulations for animal welfare and protection states that animals, in this case horses, shall be fed with food of good quality and adapted for the species. The regulations also state that they should have an individual feeding regime that enables them to maintain a normal body condition. The aim with this master thesis has been to investigate if it is possible to keep Gotland ponies on extensive pastures, during late spring and summer and still maintain animal welfare. The horses were assessed every fourth week using a welfare assessment protocol developed in line with the Welfare Quality® project (submitted, Viksten et al) where physical, behavioural and resourcebased parameters were observed. Twelve one-year old stallions of the breed Gotland ponies purchased from different breeders were used in the study.

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Cuttings of Lonicera xylosteum L. were treated with willow extract to study the response in rooting capacity. The extracts were prepared by mixing chopped pieces of Salix x smithiana Willd. with water in a warring blender. The investigation comprised 2 types of salix extracts based on differences and dynamics between twigs in winter dormancy and twigs with new shoots. To explore the rooting response, three tests were made.

Denna studie syftar till att undersöka om den grundläggande synen på identiteter USA:s ledande politikers besitter går att utläsa i strategiskt viktiga tal med koppling till USA:s insats i Afghanistan. Syftet är också att undersöka vad dessa synsätt haft för inverkan på konfliktrelationerna i detta fall. Den besvarar därför vilken grundläggande syn George W. Bush och Barack Obama uppvisat gällande identiteter. Den berör också vilken påverkan dessa identitetssyner haft för USA:s konfliktinställning och hur det förklarar konfliktutvecklingen.För att besvara dessa frågeställningar presenteras ett teoretiskt ramverk bestående av Carol Bacchis teori om problemformuleringens betydelse samt de essentialistiska och konstruktivistiska perspektiven.

Bakgrund: Det senaste decenniet har allt fler stormarknader och lågprisbutiker öppnat vilket har lett till att de mindre livsmedelsbutikerna blivit utsatta för större konkurrens. Parallellt med att stormarknaderna tagit marknadsandelar i dagligvarubranschen har även större fokus riktats mot ökat samarbete och informationsdelning i försörjningskedjan, så kallat Supply Chain Management (SCM). Inom dagligvarubranschen har Efficient Consumer Response (ECR) utvecklas ur samma idéer som SCM men med fokus på livsmedel och dess försörjningskedjor. I grund och botten handlar ECR om företagens gemensamma arbete för att integrera verksamheter, minska kostnader samt producera största möjliga nytta för slutkonsumenten. Med tanke på den ökade konkurrensen i dagligvaruhandeln samt det faktum att det finns ont om tidigare forskning om små och medelstora företag (SME:s) relaterat till SCM/ECR, är det intressant att undersöka hur dessa företag påverkas av samarbetet.

A new code for corporate governance was introduced for major companies in Sweden in July 2005. This act is to some degree a follower to the Sarbanes-Oxley Act that was introduced in the U.S.A. after the Enron scandal. The purpose of this thesis is to evaluate the effect on the controller in response to the introduction of this new act. Three controllers in major Swedish companies was interviewed and asked if and how they had been affected by this new act.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

The society is developing fast and the development is constantly on-going, new technology results in new opportunities and new problems for both companies and consumers. The use of Internet has heavily increased around the world; this means that the companies can use Internet as a channel of communication to reach the consumers. The most recent type of marketing is web marketing. The fact that web marketing is constantly changing raise the question of how effective different types of web marketing are.The purpose of this study is to investigate four selected types of web marketing. This is achieved by comparing the response from the consumers and the cost for the different types of web marketing.

The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

The purpose of this study is to determine if and how male or female everyday languagesdiffer. The study is based on ten interviews with five men and five women living inHalmstad, who are between the ages of 22-29. The interview results were analyzed andcompared with previous research on the subject. The result shows that there is adifference between the male and female informants use of language. Women laughing,using italics, hedges, the word så ?so? and response signals to a greater degree than men.The reason may be that men and women basically use different conversation styleswhen they communicate, that men prefer a public speech, intended to provideinformation and knowledge.
