A research of 14 toxic affected study sites in Sweden showed a significant increased proportion of deformed diatoms. The six metal polluted study sites in the region of Dalarna showed a 4, 2% average of deformed Fragilaria (deformed diatoms reference sites, 0, 1%). The results also indicate a significant increased proportions of deformed diatoms in the eight pesticide polluted sites in the south and middle of Sweden, compared to the reference sites, howsoever the toxic content was low. The results indicate that there are no lager differences in neither teratological forms nor variations that segregate metal polluted and pesticide polluted shells. One of the reasons may be that both heavy metals and pesticides can affect the development of the diatom shell..

One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.

This master thesis concerns the subject of a reference service named Book-a-librarian. The service makes it possible for the library-user to indulge in a subject with the help of a librarian after having made an appointment in advance. The main purpose of this thesis is to study the function of it. The methods used are a mix of literature and empirical studies to be able to comprehend and explain the practical nature of the service as well as placing the service in a theoretical framework. The empirical study is performed by a questionnaire, where librarians working with the service are asked to participate.

Det är vanligt förekommande att företag låter sig leverantörsfinansieras med handelskrediter. Den internationella forskningen är omfattande rörande vilka egenskaper och förhållanden sommotiverar leverantörsfinansiering. Syftet med denna studie är att visa vilka faktorer som är bestämmande för användandet av handelskrediter i svenska små och medelstora företag. Undersökningen inriktas på att studera vilket samband lönsamhet och skuldsättning har till handelskrediter. Företags ålder och storlek studeras också i förhållande till handelskrediter.Studien genomförs med en multipel regressionsanalys där den beroende variabelnhandelskrediter representeras av leverantörsskulder.

This bachelor thesis is about communication problems and treatment during the reference interview. The purpose was to investigate the reasons of why users? information needs are not always understood by the librarian and what to do about it. I have also investigated what kind of skills that can be useful for librarians to have and how a librarian can act in a way that makes the user feel welcome during the reference interview. The method I used was a literature study and an own study through interviews of library users.

In 2006 the government assigned the Council of Cultural Affairs the task of making an update, consisting of 50 literary titles, to be added to the existing list called Alla tiders klassiker ? en klassikerserie för skolan (All-time classics suited for school).      The idea of ??a literary canon can be considered to be a tool for transferring socially, historically and culturally constructed norms and values ??from one generation to the next in order to create and maintain a common frame of reference. The common frame of reference affect the individual's thoughts and actions as well as their sexual desires and their own perception of self as a sexual being.

SammanfattningVi har undersökt hur kreditprocessen påverkas ur kredithandläggarens perspektiv, av att det kreditsökande småföretaget använder sig av en extern rådgivare eftersom tidigare forskning tyder på att det blivit svårare för dessa företag ett erhålla finansiering från banker. Ändringen i förmånsrättslagen 2004 är en bidragande faktor till småföretagens prekära situation eftersom det försämrade bankens utdelning vid en eventuell företagskonkurs. När en småföretagares kunskaper inte räcker till, kan en extern rådgivare konsulteras för vägledning i kreditprocessen. Vårt syfte med uppsatsen var att beskriva kredithandläggarnas uppfattning om den externa rådgivarens olika funktioner i kreditprocessen samt att analysera hur kreditprocessen påverkas av att en extern rådgivare agerar i småföretagets intresse. Vi har genom en kvalitativ undersökning och studerat fyra kredithandläggare i fyra olika banker med erfarenhet av vårt ställda problem och fångat deras respektive betraktelser.

The law of preferential rights has, since the 70?s, given företagshypotek a high priority after a company has claimed bankruptcy. After the costs concerning the insolvent estate and the liens, företagshypotek has received full refund. The effect has been that the unprioritized creditors often have not recieved any of their claims after the bank have re-cieved theirs. Many countries have during the last decades deviated from this law and in 2003, Sweden decided to take the same path.

This thesis studies the negative impact that control signal saturation may have on a controlled system. Different methods that are used to compensate for this problem are also studied and evaluated. Both sensitivity to disturbances and the effect the method has on the systems'ability to follow a reference signal will be examined. Stability will be discussed, but no conclusions whether the systems are stabilized or not can be drawn. Control signal saturation will lead to a slower behavior in general.

The purpose of this study is to investigate whether intensive teaching of reading strategies at an individual level can affect reading comprehension for students in second grade. A quantitative method with quasi-experimental design is used. All students in the experimental class trained on reading comprehension strategies at their particular level five times each. Before and after training a reading comprehension test was made. The reference class did the same test.

The objective with the study was to evaluate what key persons at LFV Group (Luftfartsverket) think about-presented core values and their implementation within the company. Another objective of the study was to describe and compare the process of implementation of core values and how this affects organization culture at two selected reference companies. A qualitative method was applied in the form of semi-structured interviews with key persons at Luftfartsverket and the other reference companies.As the result a four-step program is proposed to describe the implementation process of core values: presentation, introduction, realization and follow-up. Within the implementation process it is possible to distinguish another process, which is based on core values, - introduction of new employees. The implementation of core values has contributed towards the development of the organizational culture as well as creating a successful company governed by core values..

In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

This is a study about the communication interaction in the context of the reference work at some public university-libraries and some private company libraries in Gothenburg and Borås. The primary purpose of the study is to investigate the communication interaction in a library situation. The second purpose is to deepen the knowledge, understanding and to establish what is important in this communication. Focus has been on how the intermediaries communicate and how she or he perceives this communication. The intermediary needs to manage the communication with all the different patrons and different information needs of the patrons.
