A district heating plant has the advantage that it can take advantage of the waste heat from industries and use of cheap fuels to produce heat. But for the long term is competitive requires that energy is also saved in district heating plants. One way to save energy in a district heating system is to increasing cooling to the return temperature. This leads to less power needed to drive the distribution pumps,  and that more energy could be extracted from the same amount of fuel by an improved flue gas condensation.In Karlskoga the return temperature into the district heating plant is high. They would therefore reduce the return temperature in order to extract more energy from the flue gases.

The purpose of this study is to examine a preschool's work to counteract traditional gender roles, which strategies are used and how norms about gender roles are produced and treated. The study also examines whether the preschool has an intersectional perspective in it's gender work, which analyzes how they relate to other categories such as ethnicity, race, class, age and sexuality in their work. I have been observing and conducting four interviews with teachers at a preschool with a gender profile. In my analysis I have used Foucault's theories about discourse and power. The results show that the informants had a high awareness of gender and that the main strategies used were: an individual perspective, seeing the individual and not the sex, and a gender-neutral strategy, removing everything that is gendered, for example, in language and environment.

AbstractAccording to research made by Statistics Sweden on the members of the labor union IF Metall the number of reported musculoskeletal disorders for employees working under the collective bargaining agreement for the automotive industry has almost doubled since 2003. During 2004- 2006 and 2008 male assembly workers were the occupational group with the highest amount of reported work related disorders in Sweden. To prevent musculoskeletal disorders is according to Rose and Orrenius important both for the individual, the society and the industry by reducing economic and personal costs. The purpose of this paper is to identify and analyze how the manufacturing industry is affected by musculoskeletal disorders that occur when working with line assembly and how companies can prevent them. The report aims to provide the reader with an understanding of what musculoskeletal disorders are, to which extent they occur in assembly, how companies are directed by laws and regulations and how they affect the Swedish manufacturing industry and their employees.

Detta examensarbete är ett försök att skapa en enkel handbok, där man lätt kan slå upp fakta om olika typer av gjutlegeringar. Samtidigt är det en undersökning om hur man kan förbättra kvalitetssäkringen av gjutgods. För att uppnå det förstnämnda har grundliga litteraturstudier utförts och resultatet har blivit ett antal avsnitt som tar upp det viktigaste om gjutning och gjutgods. I dessa avsnitt kan man läsa om olika gjuttekniker, legeringars gjutegenskaper, olika typer av värmebehandlingar, gjutdefekter, vanliga metoder för kontroll etc. Undersökningen av kvalitetssäkringen, och om dess förbättring, möjliggjordes genom kontakt mellan olika företag och genom att prova tekniker, såsom finita element beräkning (FEM) och gjutsimulering, och dra slutsatser från dessa resultat.

Aim: The aim of this study was to compare how patients with diabetes type 2 self-estimate their self-consciousness, problem identification, stress management and the willingness to change before and after a daycare week. The aim was also to compare if the value on HbA1c have changed after the daycare week compared to before.Method: A total of 60 patients who recived offer to participate in a daycare week at a clinic on a university hospital in Sweden. Patients replied a form (SWE-DES-SF-10) before (n=60) and three months after (n=35) the daycare week. They also left a blood sample for HbA1c before (n=60) and three months after (n=42) the daycare week. The forms and HbA1c-values were analyzed using wilcoxon´s signed-rank test and paired t-test. Results: After the daycare week estimated the participating patiens their self-consciousness and problem identification higher than before the daycare week.

The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

The purpose of this study was to compare less experienced veterinarians? subjective assessments of lameness in horses on the lunge. Previous studies on subjective lameness evaluation have mainly focused on horses trotting in a straight line and the results have shown generally low compliance. With a web-based questionnaire, 43 veterinarians assessed 60 recordings that showed both fore- and hindlimb lameness, interspersed with sound horses that were trotting on the lunge in one direction. The horses showed mild to moderate lameness.

During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.

The complexity of the mast cell is becoming more prominent. From being the cell recognized just to contribute to allergic inflammation it is now also associated with wound healing, protection against tumor growth and in recognition and defense against a wide range of pathogens. The location of the mast cell in the barrier between the external and internal environment of the body enables the cell to quickly respond to invading bacteria, virus and parasites. Diarrhea due to Escherichia coli infection, listeriosis, toxoplasmosis, Newcastle disease and bovine respiratory syncytial virus are examples of mast cell activating diseases that can affect animals in, as well as outside, the agricultural sector. Additionally, ticks and tick-borne diseases are of concern.

In the digital era, new services have entered the public libraries, like seeking information on the Internet, in databases, newspapers online etc. But many citizens do not know that these services exist. The libraries have a democratic responsibility to inform about them. In the county of Östergötland a project started in 2001 where libraries in five small municipalities built websites in which they present all their electronic services available. One of the aims was with the help of different kinds of marketing to reach special groups of people, like adult students, small companies and politicians.

Arbetet bygger på att de informationssystem som används idag men som blir allt äldre och därigenom inte klarar de krav som ställs på dem. Detta medför att informationssystemen måste migreras till modernare plattformar, då företagen dels inte klarar sig utan dess nuvarande funktionalitet och dels måste vidareutveckla systemen.Detta arbete tar upp olika sätt som detta kan genomföras på och vilka problem som kan komma att uppstå när detta sker. För att kunna undersöka detta så genomfördes ett antal migrationer. Språken som migrationen kommer att ske mellan är Visual Basic 6 och Visual Basic .net. Migrationerna kommer att ske med hjälp av ett migrationsverktyg, samt ett ramverk som i arbetet skräddarsys för just arbetets typ av migrationer.Det arbetet kommer fram till är att det sker problem vid användande av ett verktyg och även att det inte ger tillräckligt med respons på vad som gått snett under migrationerna..

This study where designed to investigate if there are any positive relationship between the extent of physical activity during adolescent's leisure time and the academic performance, and also if there are any negative relationship between the academic performance and the time spent in front of the television or computers. Another part of the study tried to find out if physical activity has a direct and immediate influence on the performance in school. 91 pupils (51 girls and 40 boys) in the 8:th year of the Swedish primary school, from three different schools participated in the study. All 91 pupils first responded to a questionnaire concerning there activities in leisure time. They where then tested in a mathematical test and the results where compared with the extent of physical activity and TV/computer time they had stated in the questionnaire.

The aim of the thesis is twofold: the first aim is to identify a number of reproductive logics that are used to construct Swedish regulation of embryo donation for reproductive use as either ethical or unethical in the governmental ? and medical discussions ? and to examine how these logics are interconnected with notions of gender and parenthood. The second aim is to identify a number of tensions that arise in the application of the governmental ethical logic on the embryo and embryo donation and discuss how these tensions can be solved with a feminist material approach. I argue that the terminology used to distinguish between genetic, biological, social and legal parenthood in my material is insufficient for understanding the value of the embryo outside its pre-human status. I therefore argue for an embryonic feminist bioethics that is attentive to the embryos post-human status, and for a reformulation of the parenthood terminology in line with what I call ?reproductive ties?..
