Jämförelse av solhybrider

Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar cells efficiency decrease with increased temperature and can with help from a solar collector be cooled and the heat can be utilized. This thesis report compares heat production and electricity production with respect of, in first hand, a solar hybrids geometry in the cooler. The theory chapter describes solar heating and how different solar cell technologies work and their environmental impact at the production and how compatible these technologies are for the solar hybrid.

Conqueror för Indigo

Conqueror for Indigo is production treated with an active chemical to maximize the ink adhesion.ArjoWiggins has found that another chemical, the candidate compound, would improve the propertiesof the paper. ArjoWiggins therefore wish to replace the current compound. To strengthenthe patent requirements for ink adhesion needs to be determined. A theory is developed to whychemicals with certain properties maximize the ink adhesion. Experiments are performed but theresults are inaccurate.

Muskeldysmorfi och dopning : Sjukdomen och missbruket som hänger ihop

The key purpose of this research has been trying to understand, and study how assyrian/syriac youth create their identity under the influence of two or several different cultures. We have also looked upon how different factors such as history, religion, language, family and school play a role in the youths identity development.We have used a qualitative method in our study where we have interviewed six assyrian/syriac youth. Because of their Christian faith the assyrian/syriac group has been forced to migrate from their countries to different parts around the world. In the new countries the group has been forced to create and live in a diasporaculture. The city Södertälje in Sweden has developed to become a metropole for this ethnic group where they have founded a substantial diasporaculture.

Ekologisk och småskalig uppfödning av slaktkyckling och kalkon i Sverige :

In Sweden in January 2005, there is only one producer of organic broilers and none of organic turkeys. But there are, on the other hand, a few small-scale producers whose housing systems to some extent are similar to what is stipulated in the organic standards. The aims of this work are to investigate what housing systems are used by the Swedish small-scale producers of broilers and turkeys, what main challenges they are confronted with and if there is an interest and a possibility for a change-over to organic production. For the first part of this work a literature study was performed with the purpose of detecting the main health problems in conventional as well as smallscale production. A special focus was on coccidiosis and leg weakness as those were considered to be of particular importance. A study was made of Swedish small-scale poultry production units. In two groups of broilers from the same producer and in three flocks of turkeys the level of Eimeria oocysts in faeces and litter was investigated.

De tekniker och metoder som använts i det praktiska arbetet såsom kontextuellt utforskande och användbarhet definieras och förklaras för att sedan användas vid argumentation kring designval för webbplatsen. Den utvecklingsmetod som använts i det praktiska arbetet har varit en Agile Software Development-metod som kallas Extreme Programming.

Methane emission from nitrate-treated tannin rich feed for cattle in Vietnam

In developing countries such as Vietnam the population consumes more animal products for example milk and meat than before which requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing animal performance reduces methane emission in terms of amount of methane in kg-1 milk and meat which today is much greater in developing countries than developed countries. The aim of the study was to investigate tropical tannin-rich legumes for their potential as a feed supplement for ruminants made in vitro.

Utvärdering av tillverkningsmetoder för svarvbommar

Profitability must be obtained through low manufacturing costs, high quality and short lead times. One of the companies on the market is Sandvik Coromant, manufacturer of tools and chips for metal cutting. This master thesis investigates the methods of manufacturing for boring bars at the manufacturing unit GVH4 at Sandvik Coromant in Gimo, Sweden.

Att minnas det förflutna : Historieskrivning i strävan efter ett gemensamt Sydafrika

This thesis is intended to respond to the extent to which South African textbooks on the subject of history is linked to the governmental policy documents and whether they are producing and reproducing national identity. The two textbooks are aimed at students in grade 10. Both books were produced in 2008 but published by different publishers.The essay is based on Norman Faircloughs critical discourse theory which has been supplemented by Michael Billings theory Banal Nationalism, which assumes that it is the national words that remind us daily of our homeland that is producing and reproducing national identity.  The survey shows that both textbooks are closely tied to the government policy document for the teaching of history. The textbooks refer to the policy, both explicitly and implicitly. The two textbooks reproduce a common national identity in South Africa based on the discussions taking place in society.

System Monitor : Ett felsökningssystem för Paperline

When an error occurs in an IT system that is vital for the production of a major industry, the consequences can be great. To quickly identify and correct errors is important as a stop in a system can lead to a break in production, which is costly for the industry. Our task in this thesis has been to develop a system for ÅF that facilitates the debugging process of the system Paperline. The system's target audience is ÅF-call personnel that provides support for Paperline 24 hours a day if something goes wrong. The system consists of a Windows service, a database and a web application and is developed mainly with the techniques C#.NET, MVC 5, Google Charts, Javascript, HTML, CSS, and Entity Framework.

Annonsmediers miljöpåverkan : när ska miljön få en reklampaus?

The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room for a deeper investigation into editorial work within the framework of the thesis. Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production, printing and distribution. Production and discarding of media equipment was not taken into account.

Nyttjande av korsningar i mjölkproduktionen

Farmers? main reason for crossbreeding dairy cows is that they have seen a decline in functional traits, especially in the Holstein breed. Throughout crossbreeding, the farmers can combine functional and production traits of different dairy breeds and utilize the heterosis effects which emerge when two or more breeds are crossed. Results from different studies with Holstein crossed with Jersey, Brown Swiss, Normande and Scandinavian Red have shown that the crosses had higher fertility, longer productive life, had fewer stillborn calves and had easier calvings than purebred Holstein. The Holstein crosses have shown very good results and sometimes even better than the purebred Holstein for fat production, which gave higher amount of energy corrected milk (ECM) and higher income for the farmers.

Att placera företagsinkubation i en Community of Practice - En studie om lärandemiljön i företagsinkubatorer

The role of small businesses is fundamentally important for the economic development in countries. Within this context, business incubation is used as an entrepreneurship development instrument to promote and support new firms in the early stage of their existence. However, research in the field tends to disregard the perspectives of incubatee entrepreneurs. The performed investigation is based on interviews with entrepreneurs from two different business incubators at Swedish universities. This study uses a Situated Learning Theory (SLT) as a theoretical framework, to examine the entrepreneur's experience of the learning environment in a business incubator.

Utveckling av ett användbart IT-stöd : för att stödja operativa arbetsrutiner

Nuclear power production carries potential risks both for the environment and for the work force. Different safety measures are employed and they stem from local rules as well as from regulatory authorities. This work describes the development of a safety promoting tool at Forsmark Power Plant, one of Sweden?s three Nuclear power plants. We describe the development of a computer based system for Pre-Job Briefing and Post-Job Debriefing.

Det (väst-) europeiska samarbetet - från säkerhetsdilemma till stabil fred

In this essay the morphing of the interstate relations in the post-World War II Western Europe is taken in to consideration in discussing how these relations were stabilized and consolidated through community cooperation to achieve a state of stable peace. It concludes that the early 1900's of Western Europe comes close to being conditioned by Herz's security dilemma and then continues to analyze the development from this state to one of stable peace. In this analysis pivotal features of the ECSC, EEC and the EC are being scrutinized through the use of Boulding's Stable Peace theory and developments of the very same, in separate case studies, in order to account for the Communities? influence on the peace process.In doing this, conclusions are drawn that external pressures can be very effective in creating an incentive to move beyond an initial state of conflicting self-images and that a stabilizing process has got to provide a long term solution in order to sustain a trustful relationship. In order to provide this long term solution the community cooperations suggests that locking in through institutionalization, harmonization, and the creation of a state of irrevocable interdependence are highly effective..

Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca

The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.
