The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

WesDyne TRC är ett helägt dotterbolag till kärnkraftsteknologiföretaget Westinghouse Nuclear och arbetar främst med oförstörade provning och visuella inspektioner av reaktortankar. Inom kärnkraftsindustrin finns ett starkt intresse och behov av att kunna utföra noggranna geometriska uppmätningar inuti en reaktortank. I detta arbete utfördes först en förstudie där lämpliga tekniker undersöktes för att finna den mest lämpade för ändamålet. Den teknik som ansågs ha störst potential var aktiv triangulering med laser. Efter vidare fördjupning inom området utvecklades och konstruerades en prototyp med tillhörande programmering, som därefter testades och verifierades.

This Master Thesis has been conducted as an assignment of the Swedish Defence MaterialAdministration and the Swedish Armed Forces and aims to examine the Target Location Error(TLE) of a Forward Observer System. The targeting accuracy of the system is vital if the systemis to be used as a sensor for precision munitions. The analyzed system, EOI (FOI 2000), wasdelivered to the Swedish Armed Forces in 2007. The targeting sequence starts with deciding theposition of the system with a GPS-receiver, continues with methods where the north direction issettled and ends by measuring the distance, direction and elevation to the target. When allparameters have been measured the system calculates the position of the target.

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

Today more and more municipalities interact across a wide range of sectors. The reasons tostart interacting are varying and for those who succeed with this form of work, there arebenefits in terms of efficiency and knowledge exchanges. But are the reasons that interactalways obvious? Sweden currently has 290 municipalities of varying size and allmunicipalities have basically the same mission, to deliver services to its residents.Information technology allows municipalities to digitize much of the workload, but theintroduction of the technique is not without problems. For small municipalities, there are greatdemands to deliver reliability and support for their internal and external services.

In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.

This research overview examines what research says about upper secondary school students' difficulties with complex numbers. The three main areas covered are general difficulties with complex numbers, how to teach the subject, and whether the history of complex numbers can be beneficial in this teaching. A historical deep dive into the history of complex numbers is also included to further investigate this idea. The results show that upper secondary school students struggle with complex numbers in various ways. The name of the subject creates a negative connotation, as it is initially perceived by students as fictional and complicated. Furthermore, a consequence of the inherently abstract nature of complex numbers is that gaining a comprehensive understanding of them is challenging.

The purpose of this paper is to evaluate the work situation for temporary workers within the field of journalism. During the past decade, influential external forces such as commercialization, new technologies and increased competition have brought great changes within the industry. As a result, employers value flexibility of manpower, not least to reduce cost, where the flexible employee is usually leased by the media company from a manpower company. Today it is a normal practice with manpower companies and this way of hourly paid form of employment. Although the temporary worker can sometimes benefit from this kind of employment, there are also significant setbacks like job insecurity.

Syftet med denna studie var att undersöka pedagogers uppfattningar om hur de använder vardagliga och icke-planerade samtal för att främja barns språkutveckling, samt vilken potential detta arbete kan ha.Undersökningen utgick ifrån en kvalitativ forskningsmetod i form av intervjuer som genomfördes med sex aktiva förskolepedagoger. De genomförda intervjuerna transkriberades och bearbetades för att kunna sammanställas till ett tydligt resultat.Resultatet av studien har bland annat visat att pedagogerna är väl medvetna om att barn utvecklar sitt språk i samspel och har därför tänkt till angående hur de vill stötta dem i denna utveckling och hur de kan vara en språklig förebild. Pedagogerna skiljer sig i sina beskrivningar av om och hur de använder sig av de vardagliga och icke-planerade samtalen som en språkutvecklande metod i förskolan.En viktig slutsats som dragits av studien är att vissa av pedagogerna är väl medvetna om vad de önskar att uppnå med de vardagliga och icke-planerade samtalen och har tillsammans med sitt arbetslag lyft detta som en medveten metod för språkutveckling, medan andra inte alls lyft det i arbetslaget.Genom denna studie hoppas jag kunna inspirera förskolepedagoger och andra som jobbar med eller på annat sätt samtalar med barn att fånga upp och ta tillvara på de vardagliga och icke-planerade samtalen. De har stor potential ? glöm inte bort att ta vara på dem..

The purpose was to determine achieved energy efficiency, costs and profitability for the studied projects. It was concluded that the Energy Collaboration is a good way of selling energy efficiency services, since the customer takes no risk and energy savings of about 15-25 % can be achieved with simple measures.

Problem formulation: The awareness and importance of Corporate Social Responsibility (CSR) is growing within both corporations and society at large. The corporate progress in sustainable development can be both profitable and essential for the potential to compete globally. The value of sustainability reporting may differ between industries and companies of different sizes. The demands for sustainability reports are expected to increase. By 2010, no previous survey on sustainability reporting practices had been conducted within Swedish corporations. Purpose: The aim of the current study was to examine sustainability reports within Swedish corporations during 2010 and to compare the findings with preceding surveys to determine differences over time and between corporations.

Ett etiskt problem bland företag är att avgöra när det är tillåtet att ge och ta emot gåvor. Problemet består i att lagtexten är otydlig samt att prejudicerande fall som säger var gränsen går mellan gåva och muta saknas. Gåvor kan därför vara direkt olämpligt i affärssammanhang. På en konkurrensutsatt marknad kan relationen mellan säljare och köpare vara avgörande för om en affär blir av eller inte. Gåvor kan därför påverka företagets framtid, och ytterst utgöra skillnaden mellan konkurs och succé.

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.
