Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.

Syftet med studien var att undersöka fallrelaterad self-efficacy mätt med Falls Efficacy Scale (Swedish version) (FES(S)) samt att beräkna rekommenderade referensvärden för totalpoängen på FES(S) hos friska äldre män och kvinnor indelade i åldersgrupperna 65-75 år samt > 75 år. Vidare syftade studien till att undersöka om det fanns några skillnader i resultatet mellan åldersgrupperna samt mellan män och kvinnor.Undersökningsgruppen bestod av totalt 70 individer över 65 års ålder, varav 45 var kvinnor och 25 var män. Testdeltagarna kontaktades via PRO i Uppsala. Även vänner och bekanta till författarna deltog i studien. Testdeltagarnas fallrelaterade self-efficacy undersöktes med hjälp av instrumentet FES(S), där testdeltagarna fick skatta hur säkra de känner sig på att utföra 13 olika vardagsaktiviteter utan att falla, maximal poäng 130.Resultatet visade att det rekommenderade referensvärdet för totalpoängen på FES(S) blev 124 poäng för kvinnor i åldern 65-75 år och 126 poäng för män i samma ålder.

Räddningstjänsten är ett yrke där risktagande är en del av vardagen för personalen, det finns många olika faktorer som påverkar hur och varför ett beslut tas före och under en räddningsinsats. Denna studie syftar till att undersöka skillnader i risktagande mellan befattningar inom räddningstjänsten, baserat på faktorer som sensationssökning och synen på den egna kontrollen av handlingar och dess konsekvenser. Metoden som användes var en webenkät baserad på två validerade tester för att undersöka dessa faktorer; Sensation Seeking Scale samt Locus of Control-test. Sammanlagt deltog 17 stycken respondenter och alla var män, befattningarna varierade mellan brandman, styrkeledare, insatsledare, ställföreträdande räddningschef samt räddningschef. Resultatet visade en signifikant skillnad i sensationssökning mellan befattningarna där de lägre befattningarna hade störst sensationssökning.

The contemporary angel-symbol is deeply rooted in our cultural history, with connotations and implications leading to that inner transitional space where all creative activity takes place. This essay investigates the history of the depiction of angels, visions of angels both ancient and modern, and includes psychological aspects of symbols as such. A closer look at surrounding symbols of angels will hopefully result in a greater understanding of the role of the angel-symbol within the context of visual culture, seen in the light of our own symbolic universe..

This paper is based on a literature review and interviews made with managers in small-scale nurseries for pot plant production. The review helped to identify the worst occupational hazards in pot plant production. The interviews provided a way to investigate how the nurseries act so as to avoid the worst hazards and what they do to even out work intensive periods during the season in order to get a more even distribution of work over the year. According to available statistics problems with back and shoulders are the most common of the physical disorders and the risk for occupational accidents are high for greenhouse workers. Most of the occupational injuries are connected to musculoskeletal problems. The handling of material is often manual and involves frequent lifting and carrying of heavy loads, the strenuous work postures and static muscular tensions these repetitive tasks are associated with causes straining and overloading.

During the last year?s Swedish agriculture have had difficult times, with decreasing prices and at the same time increasing production costs, which has led to bad profitability and faith in the future. The dairies in Sweden have also had a rough time and there have been large rationalizations during the years. In the beginning of the 20th century there were almost 1700 diaries in the Swedish countryside. There has been a large technical development during the 20th century resulting in a decrease in diaries to only 46 in the whole country today. They are owned by 15 diary companies, of which 7 large and dominate on the market and the rest are small-scale companies. With this development the confidence and feeling for the diary companies also has decreased.

This literature study summarizes the signals dogs use in intraspecific communication. The purpose is to clarify the way dogs communicate so that situations where their intentions are misjudged can be avoided. The signals are divided into olfactory, visual, auditory and tactile and every section starts with a short anatomic and physiologic description of the sense organ that is used to register the current signal type. The interspecific communication between dog and human regarding its development and function is brought up. To end with suggestions are given of how veterinary technicians in clinics can make use of knowledge about the way dogs communicate.

In the city of Kungälv, there are many important green areas without park lightning. This makes it unsafe to walk through the city's most attractive surroundings during many parts of the year. Partly in general and partly specifically for Kungälv, this paper shows that there are strong long-term arguments for making parks available by the use of lightning. This is not about lightening up the whole city, but finding the important green communication paths and parks. This paper also reflects upon how to lighten up these green communication paths and parks for best result. That is a question about creating good sight conditions ? safe and attractive parks which attracts people to use them. Offering a city's inhabitants good and attractive alternatives to using the car is an important task for city planers.

ABSTRACT This research explores how the Work Integration Center (AIC) supports unemployed immigrants in acquiring jobs and how the practical work helps immigrants in entering the labour market. It employs qualitative research approach through semi-structured interviews staff members at AIC and municipal commissioners of education and labour market in the municipality of Malmö. Its aim is to examine how governmental setup guidelines were represented in the practical work. These guiding principles of the organization are presented at the top of municipality. The findings suggest that even if the staff has no knowledge of the official measures of the integration plans, they have implemented the aims and criteria in their work with the immigrants.

The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below. Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment. Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.

This critical examination of the concept of cultural heritage is based on an overall phenomenological approach, with focus on Alfred Schütz?s further development of Edmund Husserl?s idea of the lifeworld. With strong emphasis on the subjective and intersubjective dimensions, the concept of cultural heritage is contextualized, analysed and criticized from different aspects for the purpose of enriching the discourse of cultural heritage.A literature based methodology is used, including a hermeneutic analysis of theoretical texts in the field of cultural heritage studies and the new Swedish Culture Environmental Law (?Kulturmiljölagen?) and related bills. Qualitative interviews deal with people?s notions about the concepts of culture, cultural heritage and intangible cultural heritage.

The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.
