Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.

This article is about Abrahams Children foundation and its teaching method called IE- method. It?s about how a teacher can use the IE- method in the religion lesson. There were some questions in this article that had to be answered and the questions are:- How is the form of the religion classes when a teacher uses the IE- method?- What happens in the class when you study the interaction and the communication?- Does the student?s participation increase when they work with the IE- method?- What are the advantage and the disadvantage with the IE- method?- Can the teacher use the IE- method in other classes?To get to the ?correct? answer I used many methods like, observation in the class, qualitative interview with the teacher (Lisa Andersson) and with four students (Kim, Erik, Amanda, Patrik) and I also used questionnaire.

Since January 1st 2008, companies have the opportunity to become certified by the new common customs system Authorized Economic Operator (AEO). This opportunity is presented so that authorities together with operators are trusted to ensure that it is the correct cargo that gets transported. Attends Healthcare AB (Attends) has decided to implement this certification. To qualify there are a number of criteria that needs to be met. The aim of this thesis is to verify if Attends can meet the required criteria.

Bakgrund: Lager är en betydelsefull del i företags Supply chain. Det är här produkter tillfälligt lagras och hämtas i avsikt att kunna fullfölja ordrar till verksamhetens kunder. Vid planering av lagerlayouten ska flödet av produkter underlättas, det förekommer dock ingen universell lösning för artikelplacering i varje enskild organisation. Beprövning av artikelplaceringen är betydelsefullt eftersom det möjliggör en reducering av interna transportavstånd, tillgängliggör produkter och därigenom sparas tid i orderplocksprocessen.Syfte: Syftet med denna avhandling är att identifiera den lagerlayout och artikelplacering som Formac har i nuläget. Vidare ska de problem som är associerade med dessa påvisas och därefter analyseras förbättringsförslag i syfte att öka produktiviteten i orderplocksprocessen.Metod: Kvalitativ och kvantitativ data samlades in via ostrukturerade- och semi-strukturerade intervjuer samt direkta observationer.

The aim with this study was to investigate mortality in older respectively younger beech stands (Fagus sylvatica), the different types of dead wood in the forest and the availability of coarse woody debris (CWD). The research was carried out in previously managed and seminatural stands in Biskopstorp and Frodeparken, located north of Halinstad in Halland,Sweden. Data were collected from 22 stands with at least 50 % beech and with a minimum age of 5 1 years, ranging in size from 0,67 to 19,9 ha. A transect was placed in each stand, in which the diaineter on both dead and living trees with a minimum diameter of 50 mm was recorded. On seven to 13 dead trees, depending on the size of each stand, decomposition stage, primary and secondary cause of death, amount of fungi and the type of the dead wood was noted.

The logistic business Svenska Retursystem AB was founded by the Swedish retail sector in the year 2000, and their introduction of a grey plastic crate to the Supply chain for perishable goods changed the situation for the swedish horticultural sector. The new system revealed several challenges to be tackled by all actors, from the small family firm to the bigger organisations. Whereas the initiative comes from the customer himself, from the horticultural sector ?s point of view, a refusal of the new packing is a hard decision to take. It is however interesting that a comparison between the two systems, shows in favour of the corrugated board boxes, not only concerning environmental aspects but also for economical and ergonomical reasons.

ABSTRACT Poverty, and in particular child poverty, is a serious social problem. Statistics show that the number of children living in poverty has increased over the last ten years. Earlier research shows that there are huge gaps in our knowledge of how the actors in civil society handle child poverty. With this study we hope to help fill this gap. The aim of our study is to look at how four different organisations working in the civil society in Uppsala perceive and handle child poverty.

Lichens are adapted to bright and sparse forests on oligotrophic ground. Due to a slow growth rate and high light demand lichens will suffer from competition in eutrophic environments. Therefore, lichens have disappeared from managed forests where the forest industry has increased the productivity. A reduced abundance of lichens will affect both biodiversity of the forest and the reindeer winter graze lands. It is important to understand how and for how long fertilization affects the abundance and diversity of lichens in order to protect lichen rich ecosystems. We have registered the biomass and number of lichen species in eight plots (four nitrogen rich and four nitrogen deficient) and compared fertilized Sami settlements with their oligotrophic surroundings in the nature reserves of Tjeggelvas.

The EU market is being deregulated, which sees Swedish farmers that have traditionally been governed by different support systems being forced to adapt to a free market system and having to deal with the concept of Supply and demand. The farming sector has during the past several years experienced harder conditions and the deregulation of the market has directly affected farmers. The need for entrepreneurs and that way of thinking has been identified (McElwee, 2006). Swedish farmers are neither familiar with a free market or being required to think in an entrepreneurial manner, does this therefore implicate that Swedish farmers are not entrepreneurs?LRF is a national farmers? organization in Sweden and functions as a support for Swedish farmers.

Handling materials and packaging, which is the focus of this study, requires efficient logistics, both internally and between companies. To achieve an efficient material flow, good information systems, whose role is to collect, store, process and distribute information, are required. The assumption that packagings are handled in an efficient manner is currently not a matter of course, when many companies do not prioritize the internal management of the package.The purpose of this report was to investigate how medium-sized businesses working with distribution and handling of spare parts packaging can improve their internal management of packaging. In order to answer the purpose, we have used an abductive process and a qualitative data collection. The study had Logistic Center Ljungby (LCL) at Electrolux Laundry Systems (ELS) as a case company and two other respondents, Nibe in Markaryd and Enertech in Ljungby.

These days most companies conduct some form of work for the external environment, quality and safety. In connection with this work, some companies have chosen to get management systems certified by any applicable standard for one or more of the fields while other companies have chosen other ways that are not associated with certification.In light of the fact that the individual systems are becoming unmanageable an increasing number of these companies are faced with the decision whether to integrate and coordinate these different systems or not. In order to study the possibilities of a company?s system coordination an assessment of elements particularly interesting for the company was performed. The key elements and focuses in the evaluation were staff access to information, experiences from other companies and environmental work status for some of the organization's companies.

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.

The present study concerns a concept development of a product idea that Bengt Magnuson, associate professor, had when a heavy storm caused a widespread power failure of long duration. With a basic power-producing unit one should be able to get through a power loss. The product could also be useful for other tasks if different modules are connected, e g grass mower or snow-blower.According to the product idea the basic unit will be able to produce electric power enough for a fridge, freezer, TV, and a few electric lamps. Normally the basic unit can be used e g as a mower, when such a module is attached. An increased number of tasks would make the contraption useful and tempting for those who do not own an electrical power set in reserve.

Demand has become increasingly difficult to forecast in today?s volatile markets. Being able to produce towards real demand is becoming vital for companies, since inventories of finished goods are expensive to maintain and because miscalculated products tie up capital that in the end is never repaid. More and more companies are using postponement strategies to delay the process of producing until real demand has become known. Tooling Support Halmstad is a company within the manufacturing industry, which has become aware of the benefits with postponement strategies for parts of their production.

This thesis work has been performed at Volvo Aero Corporation in Trollhättan, at the department of ?hot structures? involving aircraft engine GP7000. The purpose with the study was to investigate the possibility to reduce size of the forging of flanges on the rear turbine frame when purchasing. Thereto examine the parameters that affect the flanges motion during the manufacturing process. The goal was to provide Volvo Aero with foundation to later bring in slimmed forgings.
