En studie av hållbara alternativ till odlingstorv : - vid jordförbättring inom trädgård
Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

The Battle of Breitenfeld took place in 1631, during the 30-year war. It was the biggest battle the Swedish army has participated in. The essay analyses the battle from a Swedish-Saxon perspective, using the basic skills, ground tactical principles and management philosophy of decentralized command.The essay is based on a case study stemming from a qualitative text analysis, and is as such divided into three parts. The first part of the essay describes my theory, and explains what the different terms stand for. The second part narrates the battle and the participating armies.
Google digitaliserar bibliotekssamlingar En analys av hur biblioteksvärlden reagerar på Google Book Search
The wide spread of the Internet and new information technologies in recent years has come to effect how libraries manage and disseminate information. Search engines like Google are widely used by people who often find the information retrieval systems of libraries to be too complicated. In 2004 Google announced plans to digitise five major library collections. Organisations representing the publishing industry and authors have since then filed lawsuits against Google claiming that Googles scanning of library books infringe the rights holders copyright. Due to Googles potential impact on libraries this thesis aims to examine how Googles digitisation project, Google Book Search, has been received in the library community.
Ledinflammationer på häst och intraartikulär behandling med hyaluronsyra : en pilotstudie på hyaluronsyra X
Traumatic arthritis is a common cause of lameness in horses. One of different treatment alternatives of arthritis, is intra-articular injection with hyaluronan. As knowledge about pathophysiology of arthritis and function of hyaluronan is increasing, understanding grows about the mechanism of hyaluronan action in joints. Hyaluronan has, in addition to effects on viscosity, anti-inflammatory and analgesic effects. Extensive research and scientific studies have been made on exogenous hyaluronan.
Evaluation of ELISA and rapid test for the analysis of fecal Calprotectin
ABSTRACTBackground Calprotectin is a protein found in the cytoplasm of neutrophile granulocytes. In the course of inflammatory bowel disease (IBD), calprotectin is released during chronic inflammation in the gut. Activation of neutrophils during the inflammation is followed by activation and secretion of pro-inflammatory molecules such as calprotectin. Calprotectin is stable in stool up to 7 days and can therefore be used as a non-invasive marker for diagnosis, treatment and measurement of the disease activity in patients with IBD. The most common method for analysis of calprotectin concentration is ELISA.

Att agera "spjutspets" : - en analys av en funktion knuten till en kompetensutveckling inom äldreomsorgen
The purpose of my study was to examine a competence-development in care of older people in which some of the personnel have been ?spjutspetsar?. More specifically my aim was to investigate how the personnel managed to supervise others in the organization. My main research questions were: How do the care-managers and the care-workers persecute their functions as ?spjutspetsar?? What form has the internal meeting between the competence-development and the organization ideology taken? What possibilities and obstacles have the care-managers and care-workers been confronted? In my study my research method is based on eight qualitative interviews.
Ut ur Östersjön genom vassen : beskrivning av övergödningsproblematiken samt optimering av en reningsmetod genom skörd av vattenväxter
This study is based on AgroSeas business idea from environmental problems to valuable resource, with the objective to optimize a method to purify the already eutrophicated Baltic Sea by harvesting water plants, mainly reed. The nutrients will then be recirculated to arable land through residues from biogas production. The amount of nutrients that can be removed by harvesting the biomass
depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for an effective nutrient uptake is helophytes: reed, cattails, reed canary grass, reed sweet
grass in shallower water and lemnoideaes: duckweed and nymphaeids in the deeper parts.
Competitive species has high purification ability but requires regular maintenance to avoid channeling and overgrowth. Regarding time and method of harvest, effectiveness may be improved by: harvesting plants above the water level and after flowering, a border is kept, harvesting twice a season, a bigger machine and a regular maintenance.
This literature has illuminated a major environmental problem and it has been suggested
optimizations for a method for cleaning the Baltic Sea through harvesting water plants, but to get a
definite answer for the optimal method for each site tests should be carried out, this because many
factors determine to what is suitable for each, specific environment.

V?ld i ungas parrelationer - En kvalitativ studie om professionellas erfarenheter av v?ld i ungas parrelationer
The purpose of this study was to investigate and to bring attention to the phenomenon of violence in young relationships and to highlight the differences between adolescent and adult partner violence. Through semi-structured interviews with three school counsellors and three professionals who work with either adolescents or partner violence, gotten an insight into how they work with partner violence in adolescent relationships. The focus in the interviews was to get their perspective and experience on questions about the differences between adult and adolescent partner violence and the hardships that come with that. I concluded that youth exercise a lot of control and jealousy over each other, and that this has become normalized because of social media and different norms that are developing in the younger generations. It was also found that there are a lot of difficulties in the work with adolescent partner violence since it is hard to identify the expressions of violence in young relationships..
En ny förmånsrättslag - en konsekvensanalys
In the proposition Nya förmånsrättsregler, 2002/03:49, the government suggests a new bill of beneficial rights, or FRL. The proposition has several changes, mostly for The Banking system. One of the changes is that the banks´ individual beneficial rights shall be replaced by a general beneficial right, where the beneficial value never exceeds 55 percent of the value of insurance bonds. Previously, the beneficial value was 100 percent.The purpose of this essay is to evaluate the relationship between the banks´ activities, and the new bill of beneficial rights, especially what the effects will become for the public companies within the printing houses, with 1 - 49 employees in the Skåne Region.The survey includes a total of 142 companies and it was distributed via e-mail. The conclusions from the study are that there are tendencies of increased difficulties for companies to get their credits granted by the banks.

Prevention of diabetes type 2 among children and adolecents : Literature rewiew
The objective of this literature study was to describe the nurse?s preventive actions to prevent diabetes type 2 among children and adolescents in school age. It emerged from the analysis that the nurse is working according to three pillars; screening, lifestyle changes and counselling/education. This result showed that what often increase difficulties when working with screening are: undefined guidelines, lack of time and resources. Overweight/obesity is one of many indicators to develop diabetes type 2, therefore it is important that both BMI and waist are measured.

The authors had access to a temporary lab at Zenit and electron microscope at Halmstad University where material tests were performed. The authors have also had access to measurement equipment to measure amounts of ozone.During the work, the authors have mapped how an existing ozone generator works and then have their own development.
Automatisering av spraytorkningsprocess
ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.
