Förstärkning av bro 17-803-1 : En jämförelse av förstärkningsmetoder

AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.

Behandling av hanhundar med deslorelin :

This article presents a survey of male dogs treated with the gonadotropin releasing hormone (GnRH) agonist deslorelin (Suprelorin®, Virbac) at three animal clinics in central Sweden. Filled-in questionnaires from 110 dogs were received. The paper also includes a review of existing litterature concerning reproduction in male dogs, focusing on endocrinology, the effects of gonadectomy and the GnRH agonist deslorelin. Continuous treatment with deslorelin produces infertility in male dogs. The pituitary is initially stimulated by deslorelin leading to a rise in luteinizing hormone (LH) and follicle stimulating hormone (FSH) secretion. As a consequence the testosterone levels also increase temporarily.

Genus i förvaltningsrätten : En diskursanalys av LVM-domar

Gender in Administrative Court of Appeal - A discourse analysis of verdicts concerning compulsory drug treatmentThe purpose of this study was to examine gender discourses that could be identified inverdicts concerning compulsory drug treatment. A discourse analysis was conducted of 46verdicts from an administrative court of appeal, located in central Sweden. The main findingsof the study was that the descriptions of women, more often than men, are based on factorsother than their addiction, such as appearance and social environment. Men are in all casesdescribed by their addiction and on their own behavior. Women are presented as they riskvulnerability, while men are presented already suffer from vulnerability.

Dogs' behavioural responses to repeated positive events

Assessing the emotional state in animals is important in order to establish the quality of their welfare, therefore it is important to investigate under what circumstances animals experience these emotions and to find indicators of their existence. The aim of this thesis was to detect possible behavioural indicators for positive emotions in dogs. These behavioural indicators could be helpful to increase both dogs? and humans? overall well-being in today?s society since they could help e.g. dog owners and caretakers to interpret behaviours displayed by dogs and their intentions so they can respond accordingly.The subjects used were 9 research beagles and each dog participated in three different treatments, assumed to be experienced as positive situations, where communicative interaction was initiated with the dog by engaging in 1) physical contact (P), 2) verbal contact (V) or 3) both physical and verbal contact simultaneously (PV).

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Möjligheter till ökat utnyttjande av fosfor genom grödan med mineralgödselmedel

The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

Energikartläggning av avfallsförbränningen i Uppsala

Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of the plant. The basis in such a system is to make an energy mapping.In this thesis an energy mapping has been performed at the waste incineration plant with the aim to identify and determine the size of energy flows. The investigated energy flows are used fuel, produced and used steam, produced district heating and cooling. Also the use of electricity to run the processes has been investigated.

Septisk tenosynovit i kotsenskidan hos häst : en retrospektiv studie av 21 hästar

Septic tenosynovitis involving the digital sheath is a relatively common problem in the horse and the prognosis has been considered as poor. However, there are only few studies confirming this. The purpose of this study is to increase the knowledge about the prognosis for septic tenosynovitis in the digital sheath. The literature indicates that half or a bit more than half of the treated horses will return to previous use. The recommended treatment is debridement of the wound, lavage and sometimes application of drains and broadspectrum antibiotics. The prognosis is considered as worse when the infection is established.

Solvärme med säsongslager i Lyckebo

The purpose of this thesis is to investigate and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather facts in order to provide a picture of its current condition and potential for continued use. The thesis investigates the plant's history and problems with the rock cavern losses, and how the operation developed. It also presents the calculations regarding the possibilities of again supplementing the facility with solar energy - which is not the case today - as well as the economic conditions for it. Regarding a re-launch of solar energy, primarily a concentrating solar collector has been studied, as it has the advantages of an integrated control system.

Behandlingsmetoder vid hopparknä: en litteraturstudie

Jumper´s knee is a common overuse injury due to repetitive microtrauma to the patellar tendon. It is especially common among athletes who are involved in sporting activities that involve jumping or fast running. The term jumper´s knee was adopted after Blazina published his original paper in 1973. Its pathology can be considered as a partial or total rupture of the patellar tendon in one of its three insertions. The aim of this literature study was to review the methods used to treat this condition and the results obtained focusing on pain relief and returning to previous sport or level of activity.

Förklaringsmodeller och behandlingsmodeller kring mäns våld mot kvinnor : En litteraturstudie

Young men who commit sexual abuse is a complex topic. This study is based on litterature on the subject and the material is processed through a qualitative content analysis. The study aims to study how the litterature describes the reasons why young men commit sexual abuse. It also aims to explore what is described to be effective treatment of young men who committed sexual abuse. The study found that most of the young men who commit sexual abuse comes from families where violence and psycohological abuse occurs. Many have themselves been victims of sexual abuse.

Rissepareringens effekter på viltets nyttjandegrad av GROT

Successful forest regeneration is a prerequisite for sustainable forest management. Therefore, it is important to prevent browsing damage on the commercially important tree species Scots pine. In this study I have tested a new alternative way to increase the available amount of forage and increase the use of these resources by especially moose. The method is based on a slash treatment at harvest, where the accessibility of slash as forage is increased during final felling or commercial thinning by gathering the slash and putting the Scots pine slash on top of the slash piles. This study has compared the availability of forage, the amount of browsed biomass and the number of fecal pellet groups between conventional and slash treated stands after final felling and commercial thinning in southern Sweden.
