Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).

Djurskyddskontroll av reptiler och sällskapsfåglar. Kan djurskyddsinspektören göra en bra bedömning?

Reptiles and birds are animals that many people don?t have much experience of, so it can be difficult to do a proper animal protection assessment of these animals. It?s hard to determine if these animals is skinny, fat or in good shape, to do that it demands handling of the animal and not many inspectors that works with animal protection have experience of handling reptiles and birds. To see if a reptile or a bird is ill is difficult, when the bird or reptile looking sick it?s often too late to do something. www.blocket.se is a sell and buy page on the internet there many animals switch owner.

Smart Control : En reaktion på EU:s ekodesignkrav

The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency.

VD-Avtalet - en studie av rättsläget

Chief executives and other persons in management positions are not applicable to the same protection system as other employees. Lagen om anställlningsskydd is not applicable for example. Instead all terms and conditions are in the employment contract, which get increased importance. The employment contract for a chief executive is comprehensive. This essay focuses on employment protection, wages and compensation, loyalty during the employment, secrecy and competitive clauses.

Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

Skanskas säkerhet på arbetsplatsen : Personlig skyddsutrustning

This degree projekt deals with Skanska´s safety at the construction site with focus on personal safety equipment. The purpose of this dissertation is to examine how the rules of personal safety equipment are applied and experienced at Skanska´s construction sites.In October 2004 Skanska started a projekt to make the construction sites more safe. With use of a questionnaire we have made a survey at different construction sites. 80 questionaires have been handed out to Skanska´s employees in the southeast region. While they were handed out we conrolled if the employees at Skanska´s construction sites used head protection, easy visible clothing, safety shoes and identification cards.The result of the survey shows how the rules are applied.

Konstruktioner av kvinnligt och manligt i våldtäktsdomar : En kvalitativ textanalys

The purpose of this study is to examine constructions of plaintiff [woman] and the defendant [man] in Swedish rape convictions from 2013. The cases in this study cover acquaintance rape. We also intend to analyze the constructions of the sexes in relations to each other. The study is completed by a qualitative text analysis, with inspiration of a hermeneutic interpretation. The result is presented by four categories: the worthy of protection of the woman, the penalty of the man, the complicity of the woman and credibility.

Djuren och den ädla människan : Aristokratins roll i den svenska djurskyddsrörelsens framväxt 1875-1905

The aim of this paper is to analyze the influence that aristocrats in Sweden had on the Swedish movement for the prevention of cruelty to animals, and why especially aristocrats started it. The sources I have been using are speeches and texts written by persons who were involved in the movement. I have also studied rapports from the three largest societies for the prevention of cruelty to animals. In the sources I looked for terms, expressions and opinions that can be paralleled whit the aristocratic ideal and opinion. Things that can relate to aristocratic urban people.

Elevers förståelse för begreppen area och omkrets

Syftet med detta examensarbete är att undersöka om och hur elever uppfattar begreppen omkretsoch area. Då vi båda studerar till matematiklärare anser vi att detta arbete kan stärka oss i vårlärarroll samt utveckla oss inom arbetsområdet geometri.Vi började med att göra en diagnos med ca 40 elever. Genom att djupintervjua tre av elevernafick vi en bättre förståelse för varför eleverna svarade som de gjorde på diagnosen.Genom att göra en läromedelsgranskning av de aktuella läroböckerna ville vi se om dessa kanspela roll när det gäller elevernas kunskap inom detta område.Resultatet visar att de flesta eleverna klarade att räkna uppgifter inom området omkrets ellerarea och använda sig av dessa begrepp när uppgiften var ?given?, på så sätt att eleverna får vetavad som ska räknas ut (area eller omkrets). Problemen dyker upp när eleverna får svårareuppgifter som är konstruerade på ett sådant sätt att de inte får en given metod att lösa uppgiften,det vill säga när det är oklart hur eleverna ska angripa uppgiften..

Död ved i vatten - funktionella strukturer och dess påverkan på öring (Salmo trutta, L.)

The background to this work was to see if there was a connection between large woody debris (LWD) and the presence of brown trout in our Swedish forest streams. Previous researches by Degerman et al. (2004) have shown that there is a strong correlation between the amount of dead wood and the presence of brown trout. The goal was then to find a way to restore, maintain and increase the trout habitats by constructing and adding manmade wooden structures that would mimic natural deadwood and its features in flowing water. The inspiration was partially taken from a water restoration program in the Klamath River of northern California, USA.

Det personliga betalningsansvaret i 25:18 ABL : Tidpunkten för en förpliktelses uppkomst i leveransavtal

Currently there is a tendency in the EU to adjust the minimum-capital requirement. In France and Germany the requirement for private limited liabilities has been totally abolished, whilst other countries have chosen to reduce their requirement. The Swedish law concerning the minimum-capital requirement is from 1st of April 2010 being lowered to 50 000 SEK. In common law jurisdictions such as United Kingdom and USA a minimum-capital requirement does not exist. The european main argument to keep such a requirement is that it accomplishes a creditor protection.

Rekgrupperna i de svenska ingenjörbataljonerna : Är de bara ögon i terrängen eller har de möjlighet att bita ifrån?

This paper describes the Swedish reconnaissance squads in the engineer battalions, their equipment, tasks and organization. An analysis is made to compare the present weapons and fire power of the reconnaissance squad with an extended weapon alternative. The analysis focuses on the abilities effect, protection and movement in different situations typical of a reconnaissance squad.The facts that are presented in this paper are mostly founded on the new field manual FältarbR Dyktjänst 2007, which regulates much of the reconnaissance activities. The aim of this paper is the making of a contribution in the developing progress of the new field manual and the reconnaissance squads in Swedish engineer battalions.The result of the analysis shows that the extended weapon alternative would be an asset..

Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.

Opportunities for improved environmental sustainability of a wine producer in South Africa : natural resource management and climate change adaptation and mitigation

South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.
