The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.

The  change that has occurred during the past few decades concerning the development of electronic records, information technology and the constantly increasing quantity of information, have confronted the archival discipline with new challenges. In the digital world, the concept of ?record? has changed from representing something lasting and physical to something much more abstract and transient. The way to approach archival description has also changed, from focusing on the static preservation of archival records, to documenting the transactions of organisations, and to clarify operational processes. The discussion about the general purpose of the archival discipline, and its place in a changing world, has led to a new approach to archival description.

Our common future involves many important challenges. People and nature need to improve the relationship in order to reach an ecologically sustainable development. In a society where consumption of products steadily increases, the consumer awareness about social and environmental issues connected to the products becomes an importent factor. More and more companies choose to work more actively with these issues and more and more products get labelled by some of the eco labelling organisations. From the cradle to the gate means that a study has been done on a part of a products life cycle.

Wind power is a growing energy sector in Sweden. However, it still represents only a small part of the total electricity production, about 0.7%. In order to create good conditions and to facilitate the establishment of wind power in Sweden, the government has for example, created a national centre for wind use. The objective has been to reach the governmental goal, which is an expansion of wind power by 10 TWh by year 2015 compared to the level in 2002. The Swedish electricity market was deregulated in 1996 which refers to the introduction of a competitive market in electricity production and trade.

A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.

The Nasometer is a non-invasive acoustic measuring instrument that quantifies the ratio ofnasal resonance in speech. It can be used as a complement to perceptual judgment of speech impediments, for example, in patients with cleft palate and velopharyngeal insufficiency. Inorder to determine if a nasalance score is abnormal, it must be compared to norm data. The main purpose of the study was to collect reference nasalance scores in children between fourand five years of age in Linköping. An additional objective was to compare the results tonorm data collected in Umeå.

This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.

Recent studies show that manufacturing companies to a larger extent use historical cost accounting in their internal accounts, at the expense of calculated costs. The explanation behind this is claimed to be that firms are subject to careful scrutiny by the stock market. Consequently, top management stresses the need of evaluating all parts of the firm from external accounting. However, lower management levels express a general concern that the incentive to invest in machines will decrease. This master thesis aims to investigate whether or not there is an objective reason behind this concern.

Syftet med denna undersökning var att utforska den lärandes perspektiv genom att lära oss spela ett nytt instrument. Genom att försätta oss i en sådan situation och sedan granska våra egna läroprocesser hoppades vi kunna bemöta våra framtida elever med djupare förståelse. Vi ville på detta sätt försöka synliggöra faktorer som påverkar vårt lärande och bilda oss en uppfattning om hur vi påverkas av dessa.Undersökningen utfördes med oss själva som studieobjekt där vi under hela processen noggrant förde dagbok över våra upplevelser, både skriftligt och med ljudande inspelningar. Inspelningarna bifogas som en bidragande gestaltning till det avsnitt som kallas Processen. I Processen förekommer diskuterande tolkningar som fullföljs i Epilogen.Vår studie visar att det är svårt att till fullo sätta sig in i en nybörjares roll.

Sudan has always showed great potential in the poultry industry, but it has not been until now that this potential has blossomed and is growing quickly. As large agribusinesses1are taking over the market shares within the urban areas, smallholders2 have been put out of business. They are not able to compete with mass production and lack financial assets to improve their production techniques. Contract farming is defined as initiatives from agro industrial companies to secure access to smallholder produce and has in developing countries become a way of allowing the poor to participate in a larger market (Farrington, 1999). The aim with this study was to investigate the suitability of implementing the contract farming concept within the poultry industry in Sudan today. The study is a qualitative field study and the authors have conducted qualitative interviews with respondents involved in the poultry industry in Sudan.

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

This study is about the use of textbooks in teaching English as a second language and about teachers? attitudes and opinions of using textbooks during lessons. The aim of the study is to receive a deeper understanding of the use of textbooks in English teaching and to learn about why teachers choose whether to use the textbook approach or not. The study contains an analysis of the textbooks the teachers in our study used. The analysis shows the actual content and the types of texts together with the design and the structure of the textbooks.

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

A growing issue in the construction industry is how production can become moreefficient by using logistical solutions. Companies can minimize the cost of a project byreducing the time to perform the work.The purpose of this report was to examine the logistics related to pipe trenches forSIAAB. The report's focus has been on solving problems and planning that wouldfacilitate the work of the project Vaksala-Lunda Etapp 3.The case study consists of interviews with SIAAB's employees and an observationwhere the progress of a traditional pipe trench has been documented using checklists.Questions to the report?s case study come from the theoretical part, which is basedon literature on construction management and logistics in general. The observationlasted five weeks and the biggest time-consuming events that affected the pipe trenchduring this time, has received most attention.
