This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

Den svenska handelsflottan har de senaste åren varit utsatt för massiva utflaggningar vilket har lett till att många sjömän har fått gå i land eller sökt arbete under annan flagg. Trots problemen med utflaggning och en potentiell minskad arbetsmarknad har sjöingenjörsprogrammet de senaste åren inte haft några större problem att fylla sina utbildningsplatser. Framtiden är fortsatt oviss och konkurrensen från andra sjöfartsnationer ökar. Syftet med denna undersökning var att undersöka vilka bakomliggande attityder och förväntningar som gjorde att studenter år 2013 valde att börja studera på det fyra åriga sjöingenjörsprogrammet i Kalmar, samt att mäta inställningen till den allt mer krympande svenska handelsflottan. För att genomföra detta arbete användes en enkätundersökning där förstaårsstudenterna på det fyraåriga sjöingenjörsprogrammet utgjorde populationen.

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

Environmental chemicals are transported to the Arctic through the air and oceans, once within the Arctic they spread through rivers, lakes and other watercourses. Polar bears and sledge dogs in-gest high concentrations of environmental chemicals since many of the chemicals are fat-soluble and their diet mainly consists of marine mammals. The aim of this study is to describe how environmental chemicals spread in nature, how they reach the polar bears, and finally how they affect the animals reproduction, with reproductive hormones and genitals in focus. The animals are exposed to a cocktail effect which complicates the assessment of the chemicals impact on the reproduction. Studies show that the genitals can decrease in size or become malformed, sexual maturation can be affected and the reproductive hormones can be disturbed.

FLUTD - Feline Lower Urinary Tract Disease ? is a complex disease and a common sight in the veterinary setting. Although FLUTD excluding urethral obstruction may be discomforting for the cat and its owner due to symptoms such as periuria, stranguria, hematuria, dysuria and pollakiuria, obstruction presents an acute and potentially lethal form of the disease as a result of uremia and disturbances in fluids, electrolytes and acid-base balances. A study of literature has been performed to investigate the causes of FLUTD with urethral obstruction and the actions available to the owner to avert them. Potential causes of obstructive and non-obstructive FLUTD have been found to include infections, uroliths, urethral plugs, neoplasia, anatomic abnormalities, trauma, neurogenic or iatrogenic causes. Most commonly a cause cannot be identified and the terms idiopathic FLUTD or feline idiopathic cystitis are used. As the mortality rate due to urethral obstruction likely is somewhere around 5.8-8.9% and FLUTD including and excluding urethral obstruction constitute great inconveniences, precautionary measures are warranted.

The main aim of this study is to investigate which structural ideas that lies behind the European Union?s marine operation Atalanta that has been put into motion to counteract piracy and robbery outside the coast of Somalia. In order to do this, we have with the use of the theory of weak states, intervention as well as sovereignty, investigated EU?s document in the question with the use of the idea centered analytical method. The questions that has guided this study, lies both on an empirical and theoretical level.

The Savi?s Warbler (Locustella luscinioides) is a recently established bird species in a few reedy shallow lakes of southern Sweden and has only been found nesting for the last twenty years. Little is known about the species' habitat preferences, breeding biology and demands for specific territory structures at breeding sites in Sweden. Knowledge of a newly established species? habitat requirements is essential to maintain a viable population and design action plans.

Floating housing is a concept gaining ground in Sweden. The dwellings are different in many ways from traditional homes, not only regarding flotation, but also several other technologies. The purpose of this thesis is to emphasize the qualities that exist in living on water. The ambition was to present a proposal for a floating residential area located in Jönköping, containing homes of varying sizes, and to present their technologies. In order to find inspiration and solutions studies have been made on existing floating homes in Stockholm and Kalmar, focusing on their technical and functional solutions.

Hemoglobin is built up from protein and heme groups which give the blood its red colour . Hemoglobin transports oxygen and carbon dioxide between the lungs and other tissues in the body. Normally, a piglet has a hemoglobin value of 130-150 gram per liter blood, and the lower limit before anaemia appears is 80 grams per liter blood. The immune defense is also dependent upon the presence of iron in hemoglobin, since iron participates in different enzyme systems. When the piglet develops anaemia, it becomes pale and thicker around the neck.

Antifouling paint containing the biocide bisTributyltinoxide (TBTO) has been used since1960 to reduce the occurrence of fouling on hulls on boats/ships. January 1st, 2003 theantifouling paints containing TBTO were prohibited. This ban covered all use of paintcontaining the substance TBTO. The ban was introduced because of alarming observationssuch as development of imposex in aquatic non-target organisms. Imposex is the impositionof male sexual characteristics on mainly female marine snails and occurs due to exposure toTributyltin (TBT).

The objective of this thesis was to get more knowledge about how to design a dairy farm reducing the working hours and the work tasks whit high work load. I will try to reduce the working hours and the tasks whit high work load on my own farm witch I am about inherit. Today, the old stanchion barn has room for about 60 cows and 74 young cattle and need two men to run it every day. The total acre is 188 hectare, 100 hectare forest, 65 hectare farmlands and 23 hectare natural pasture. I have studied two solutions. In the first solution, I will use my old barn for young cattle and build a new barn for the cows.

The piglet mortality rates have become a major issue in today?s pig production. While other production traits such as number of born piglets or produced piglets per sow have been improved, the mortality rate has escalated. High mortality rates before weaning does not only affect the economy but must also be looked at as both an animal welfare problem and an ethical issue. The background to this problem has been addressed many times, and its salvation has also been addressed by breeding.

A secondary and a pioneer tree species can with advantage be included in a mixed stand to increase the use of sunlight. Nitrogen-fixing plants have been shown to increase the supply of nitrogen in the soil by, for example, litter fall. This deposition acts as a biological fertilization, which may be used by non-fixing plants. Alder is a nitrogen-fixing, pioneer tree species that loses its nitrogen-rich leaves late in the autumn. The aim of this study was to examine the effect on the total volume of production, when different proportions of nitrogen-fixing Alder were part of spruce stands.
