Födosammansättning hos gråsäl (Halichoerus grypus) samt test av flotte för insamling av sälfekalier.

During the 1960´s and 1970´s the number of Grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the Grey seal population started to increase. Today Grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The Grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the Grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the Grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

Fällning av kisel från avloppsvatten vid Hellisheidarvirkjun - experimentell studie

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

?Poor, fucked-up, kinky, philanthropic Christian Grey? : en studie i maskulinitet och fantasier om manlig sexualitet i romansviten Fifty Shades of Grey

The current paper is a study of the character Christian Grey in the EL James trilogy Fifty Shades of Grey. The main aim is to find out how masculinity, sexuality and gender are constructed in this erotic fantasy. More over terms as femininity, unmanliness and gender have relevance to the study. Several studies have been done on romance novels and Harlequin in particular from a gender perspective, but few of them from a masculine point of view. Hence, no earlier study has been done on Fifty Shades of Grey with masculinity studies as the main tool of masculinity, or with theories of romance.

Local stakeholders? willingness to conduct actions enhancing a local population of Grey Partridge on Gotland ? an exploratory interview study

The population of Grey Partridge is decreasing worldwide as a result of anthropogenic activities. Increased agricultural production, requiring homogenous farming landscapes and increased use of pesticides are believed to be the main factor causing population declines in the Grey Partridge. Actions to enhance Grey Partridge populations are available; however, those actions are vain if the acceptance to conduct them is low. To gather information about acceptance among farmers, hunters and the County Administrative Board towards 18 available actions enhancing the Grey Partridge population, nine face-to face interviews were conducted as an exploratory case study. The results showed that willingness to conduct enhancing actions differ between and within the groups of stakeholders.

Identifiering av parametrar för tillståndsbedömning av en vattenkraftstation

The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..

Cutaneous Melanoma in the Grey Horse

Equine cutaneous melanomas arise much more often in horses with a grey coat color than in horses of other colors. Some scientists have in different studies come to the conclusion that the melanomas are neoplasms which can be classified by examining their histological and macroscopic features. The more defined and demarcated a tumor is, the more benign it tends to be. Other scientists believe that the skin lesions are the result of a pigmentation disorder that is linked to the greying of the coat color. According to this theory, the lesions are not malignant although they have the ability to metastasize.

Radialtätning till Retarder

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Den uppklädda människan : en diskussion kring den gropkeramiska klädesstilen

This thesis discusses the dress code during the Pitted Ware culture on the Swedish island of Gotland. Eight Pitted Ware grave-fields have been analyzed; only 74 skeletons have been identified with some sort of ornament that could have been attached to clothes. The grave-fields are rich in finds and in people nearly every age group is present. The analysis has shown that there are clear differences between the genders. The female always has some sort of seal tooth ornament around her waist and thighs.

Konstruktion av testrigg för moderna ångexpandrar

This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

Smart plombering och märkning

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

Ursprungs- och kvalitetsmärkningens betydelse för konsumentens val av krukväxter : en studie om mervärdet av Mäster Gröns co-branding med Svenskt Sigill

This essay has been made on behalf of the co-operative society Mäster Grön, which is selling ornamental plants to retailers in Sweden. The aim of this study has been to find out what added value Mäster Grön gets from their co-branding with the Swedish Seal of quality. The main topic of discussion was; how much value added does this co-branding give to Mäster Gröns pot plants? Are there differences from a customer point of view in value added between a garden center and a retail store? How much weight does the costumer put on the branding when buying a plant? Does the customer know what the values of Mäster Grön and Swedish Seal of quality mean? Two questions of lesser worth were asked to the consumers about what they thought about the protective plastic around the plant, and if they were interested in getting more information about the origin as well as the method of production of the plant. The study was divided into two parts, one in which customers were observed and one where the customers answered a survey.

Hur sexualiteten konstrueras i webbartiklar om filmen Fifty Shades of Grey : En foucauldiansk diskursanalys om hur den normala sexualiteten görs

This qualitative study aims to study how sexuality is constructed in web articles on the movie Fifty Shades of Grey. The study is based on a social constructivist perspective where language is seen as constitutive of reality. The study is based on a Foucauldian discourse analysis which is used in order to see what is excluded and included in the articles? construction of normal sexuality. The result shows that there are similarities in how the web articles produce normal sexuality.
