Common species of freshwater mussels may, like the freshwater pearl mussel (Margaritifera margaritifera) have a drastic decline in number and there is several reasons, like sedimentation, a decline of host fishes, introduction of alien species, nutrition leakages from agriculture and pollutants of medic drugs and poison. Ann Gustavsson made in the year of 2007 a study over rejuventation of freshwater great mussels in nine watersystems and considered that the rejuventation within the populations were all along the line poor. This study orients from her work and points to determine if there is a connection between the poor juventation and pollution of nitrogen and phosphorous from industries and private sanitations. The study was performed with the software program ArcGIS9.2 to take out drainage areas for the concerned habitats and contact was made with the concerned authoritys. When it comes to supervision of private sanitations is it the countys and for industries is it the county administrative board.

The aim of this study was to find out how many and which of the herbs used for horses that have been scientifically studied with results to justify the use. In order to find out which herbs that are commonly used by horse-owners a phone interview was performed where six companies selling herbs for horses was contacted and asked to provide information on the most sold herbs for horses in Sweden. Devil's claw (Harpagophytum procumbens), chamomile (Matricaria recutita), dandelion (Taraxacum officinalis), nettle (Urtica dioica) and monk's pepper (Vitex agnus-castus) where the most sold herbs, followed by marshmallow (Althaea officinalis), burdock (Arctium lappa), marigold (Calendula officinalis), purple coneflower (Echinacea angustifolia/purpurea), cleavers (Galium aparine), licorice (Glycyrrhiza glabra), rose hip (Rosa canina), thyme (Thymus vulgaris) and vervain (Verbena officinalis), in no particular order. Of the most used herbs, research with focus on the use for horses was found for purple coneflower, licorice, devil's claw, monk's pepper, rose hip, thyme, and vervain. These studies did not cover the whole range of traditional use for the mentioned herbs, and more studies are needed to be able to claim that these herbs have, or have not, scientific support for use in equine management..

Social work is a social phenomenon, existing in most societies, that has given rise to a multitude of special organizations and professions. For that reason social work is dealing with a complex identity. The purpose of this study is to illustrate how social workers and the scientific discourse interpret the concept of social work. In addition to that the study intends to show similarities and differencies. The research process containes two studies, one based on qualitative interviews with five social workers and the other consisting a surway of academic litterature.

In Korsnäs district Dala Väst there were problems with information concerning their younger forests, mainly those in pre-thinning stage. They were divided into large, heterogeneous stands with often poor stand data quality. In 2006 an aerial photo interpretation of the young forests was conducted to fix these problems. Necessary information to get from the interpretation were silvicultural management suggestions, new stand delineation and new stand data. This thesis is supposed to evaluate the quality and usability of the interpreted data. To evaluate the interpretation an objective control inventory was conducted in 60 stands, either through callipering or counting stems.

With increased milkproduction in our dairy cattle, comes a risk for a reduced fertility. Studies performed on animals and humans have shown that it is possible to manipulate the oestrous cycle through exposure to pheromones. This means that pheromones could potentionally be used to make reproduction more efficient. To evaluate the bioactivity of the substances in question, there is need for a bioassay. In insects, pheromones can induce a changed cardiac activity.

The purpose of this Master?s thesis is to investigate the legal practice of valuation in arbitration board proceedings concerning freeze-outs after non-cash take-over bids. We find that the most important method for valuing the shares offered in exchange for the shares of a target company is to take the volume-weighted average of the quoted prices of the shares offered in exchange during the acceptance period of the take-over bid. This thesis is a complement to previous studies by Peter Jennergren (1996) and by Andrea Lundqvist and Victor Ludvigsson (2007) of how the Balken case (a freeze-out case that was eventually decided by the Supreme Court of Sweden, in 1996) has affected the legal practice of valuation in freeze-out arbitration board proceedings. We have undertaken an empirical study of 48 freeze-outs between 1985 and 2006 where shares in the bidding companies were offered in exchange for shares in the target companies.

The examination is focusing on the person who is working in the supervising position in a company. Two different case studies performed with qualitative interviews. One case study is in the service industry and the other case study is in the manufacture industry. The aim with this study is to bring greater understanding to the eventual problems of identity that a supervisor canexperience because of his/her working position boarder between groups. This considering three roles of the supervisor; one role as asupervisor, one role as a colleague and one role as a friend.

Previous research has focused limited attention on how personality affects job search for university educated people in work and no studies have focused on the difference between active and passive job seekers. This survey-based study that examined university educated economists and engineers with 5-25 years of experience, showed that career ambition mediated active job search for the personality dimensions of openness, agreeableness and extraversion and also gave clear evidence that active job seekers have lower levels of job satisfaction, and higher levels of career ambition, agreeableness and extraversion, compared with passive job seekers. These findings provide a more nuanced picture of the impact of different recruitment strategies and provide a starting point for in-depth studies on passive job seekers.

Plant tRNA isopentenyltransferases (tRNA-IPT, EC 2.5.1.8) have two roles, modification of tRNA and contribution to cytokinin synthesis. tRNA-IPT is among the best studied of the tRNA-modifying enzymes, but little biochemical information is available and none for the plant enzymes. Therefore two sets of experiments were conducted. The first one aimed to determine the kinetics and substrate specificity of the tRNA-IPT AtIPT2 from the higher plant Arabidopsis thaliana. The second project aimed to study the role of IPTs from the moss Physcomitrella patens in the production of cytokinin hormones.

Sexual harassments have since long been an issue all over the world and schools have not been an exception. Reports from Swedish secondary schools show how 47% of the female pupils state that they have, sometime during their time in school, been the victim of sexual harassment. Other studies claim that pupils exposed to sexual harassments will develop low self-esteem and a decreased sense of self. The Swedish curriculum state that all children shall have the right to a harassment free school environment, but still many pupils claim to be exposed to sexual harassment in school. Several studies have theorized about why sexual harassment is so prevalent in schools but what do the pupils think? This study aims to reveal and analyze pupil opinions about sexual harassment; what do they think it is and why do they think it occurs? This will be done from a post-structural feminist point of view with focus on the shaping of identity among the respondents.

There are many theories why animals play but none have jet been proven. During observation on Canids, play seems to be important when they learn to control the intensity of the bite and to facilitate the social structure within a group. When dogs play they perform behaviours that otherwise are used during hunting, reproduction and aggression that in another context would be for example hostile. The dog is one of the species that we humans have domesticated and they have been exposed to an intense and concentrated breeding so they can function in different areas, for example herding and hunting. This breeding has resulted in that the pure bred dogs can be very different between the breeds.

The main purpose of this essay is to identify opinions of masculine and feminine language in a written text. The aim is to examine whether the reader of a text can define the anonymous author?s sex, judging only by elements such as choice of words or sentence structure. Are there any differences between the sexes as they appear in written language, and is the common man able to make this distinction? The essay is based on several studies on people?s ideas on masculine and feminine language, as well as studies on actual differences.

The purpose of this thesis is to investigate the outreach services for children and youths in a specific area, in this case Västra Götalandsregionen.
