In a sustainable society the use of renewable energy and recycling of materials is of high importance. Wastewater treatment plants use large amounts of energy in the processing of wastewater. This study seeks to evaluate wastewater as an energy resource and to examine treatment plants potential to become sustainable energy producers. The study is based upon the internal processes of Himmerfja?rdsverket.

With this research we aim to examine foster parents and social workers perceptions about the relationship between foster parents and the foster child?s biological parents and their perceptions about the support to the foster parents in the contact with the child?s biological parents. The research will provide a deeper understanding of the actors? perceptions and explain possible differences in their opinions. This study has a qualitative approach and contains eight semi-structured interviews with foster parents and social workers in a smaller town in the south of Sweden.

Sisyla is a joint project between the counties of Skåne, Blekinge, Jönköping, Kronobergand Kalmar in Sweden. A geographic database has been built with the aim to study theservice situation of the area. The main purpose of this thesis is to find a method toinvestigate the quality of the Sisyla database and to apply it. The method is adjusted tothe standard ISO 19114.

The purpose of this study was to investigate the association between physical activity and perceived stress, energy and musculoskeletal disorders among office-workers and warehouse-workers and also to see if there were any differences depending on work-place and gender. The method that was used to collect data was three different validated questionnaires that measured stress and energy (the Stress-Energy questionnaire), musculoskeletal disorders (intensity and localization of pain, a Pain Drawing questionnaire with a VAS-scale) and physical activity (IPAQ ? the short version). Eighty-eight workers participated in the study. Forty-seven of them were office-workers and forty-one were warehouse-workers.

The purpose of this study is to examine the role social media canplay in a school library context, based on a theoretical model,called ?A new model for the public library in a knowledge andexperienced society? by Henrik Jochumsen, Dorte Skot-Hansenand Casper Hvegaard Rasmussen.The bachelor thesis aim to answer three research questions, theyare as follow: Which request of social media is there by teachersand pupils at a high school library? Which social media is the mostrequested by teachers and pupils at a high school library? Andshould the library services for teachers and students be improved ifsocial media were used at a high school library?The methodology used for this study was an inquiry investigation.My findings are presented in a context of previous, relatedresearch and the study shows that teachers and pupils are wellinformed of what social media is and they use social media whenthey are at school.The thesis also shows that the unit I study, a vocational trainingunit, is more or less interested in what the school library can do forthem with social media.They seldom are at the school library and they seldom use theteach platform were they can find library services.This result can open up for the school library to meet the users at anew arena with for example social media..

SAMMANFATTNINGIntroduktionKommunikationen i ett vårdteam har stor betydelse för samarbetet kring en skadad patient. När kommunikationen brister kan det leda till sämre omhändertagande av en traumapatient. Ledaren för teamet har en betydande roll för teamarbetet. På Försvarsmedicincentrum i Göteborg tränas teamen med medicinsk simulering med fokus på teamarbete.SyfteSyftet var att undersöka hur kommunikationen erfors och påverkade samarbetet inom teamet under en medicinsk simuleringsövning.MetodFokusgruppintervjuer genomfördes av teamen efter en övning i medicinsk fullskalesimulering. Frågorna var semistrukturerade.

Since events of September 11 and the subsequent conflicts surrounding the event, the war against terrorism has been constantly present. It has been used several methods and strategies to address these threats, including a method current in use, the targeting method. The method refers to use few but precise attacks to knock out key functions within these organizations, mostly individuals in the higher command and control structures within these organizations. The effectiveness of the method has been put in question when the majority of the terrorist organizations continue their strife, in some cases even increasing its intensity. The purpose of this study is to investigate which role the higher command plays in these organizations ability to wage war.

AimThe aim of this study was to find out how the research that has changed CPR training developed from a historical perspective. The question at issue was: When the recommendations for chest compressions/ventilation, defibrillator and education have been changed, what kind of research led to the development?MethodTo fulfill the aim of this study we chose a review process. First we read the international guidelines for cardiopulmonary resuscitation (CPR) published by the American Heart Association (AHA), from year 1980 until year 2010. Secondly we chose the most important changes that had been made within the issues we had selected, then we examined the research that had supported these issues.

IntroductionSuccessful training is a key for athletes to make progress in their development. Training must not just involve overload, but also must prevent the combination of excessive overload plus inadequate recovery. Athletes can experience short-term performance decrement without severe psychological or lasting other negative symptoms. Too much hard exercise or too little sleep can cause overtraining, a condition in which the subject can prevent to be away from the sport for several weeks or months. Previous studies have detected that it is important to avoid overtraining.

The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

A literature study and a field trial have been carried out in order to investigate the physiological response of potato plants to different soil moisture levels. Higher yield, quality and number of tubers can according to the literature be obtained if constant high soil moisture is kept during major parts of the growing season. A field trial was set up where drip irrigation was used as an alternative to conventional irrigation techniques to maintain high and constant soil moisture. The application of water in the drip irrigated area was monitored and adjusted on a daily basis so that the soil moisture stayed as close as possible to the recommended level. The sprinkle irrigated area was irrigated according to traditional practices with approximately 35 mm every 7th to 10th day depending on the whether.
