Studies have shown that air pollution, as well as bark fissure depth and sun exposure of a tree can have an effect on lichen growth as well as abundance of lichen species. The aim of this study was to find out the relative importance of these factors. 211 oaks in south eastern Sweden were surveyed for presence of 17 lichen species, as well as the total number of lichen species. Half of the trees were situated in urban areas and half in the countryside. For each tree the bark fissure depth was measured and the sun exposure of the trunk was estimated.

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

This essay investigates, on the basis of the medieval letters, diplomas, how the medieval monasticism contributed to the maintenance of the Danish society's gender structures.

Finally, a continuous comparison is made with Catharina Andersson's results in her dissertation, in which she examines the social structure in the Swedish medieval society. The primary material in the study is the Danish diplomas. 41 diplomas were found relevant for this study.

The aim of this Master thesis is to make a survey of the public library staff-relations at work and discuss relationship marketing as it applies to public libraries. Relationship marketing involves the establishment, maintenance and development of users and other library-related relationships, including the relations among the library staff itself. Good relations among the library staff is a necessary condition for good relations with others. The focus of relationship marketing is at the user?s needs, wants and demands instead of the library collections and services.

The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

The essay is written at the request of Nyköping municipality park management by PatRadestedt who wanted a design proposal for one of the five courtyards at the Tessin Schoolin Nyköping. The Tessin School is located 2 miles from the center of Nyköping and the schoolhouses approximately 900 students. To make a design proposal for the courtyard that lies atthe canteen I decided from the outset that I wanted to take some of the Tessin SchoolStudents' opinions and wishes regarding their own outdoor spaces. I had a workshop witheight students from the arts program with the image orientation in which they had to drawand tell them what they wanted to do in the courtyard. The outcome of the workshop, Iused to move forward in my future work with a concept that fit into the environment, wethen apply it in my final design proposal.

Collaboration is a form of organization on the rise in Sweden. For health care, it is ofinterest to collaborate with industry to ensure that needs for specialist education andtraining are met and that products developed meet the relevant requirements.Conversely, industry actors have an interest to have a close collaboration with healthcare in order to gain insight into customer needs, provide information about theirproducts and to test products in development.The starting point of this study is an agreement and regulatory framework for formsof collaboration between public health care in Sweden in general and thepharmaceutical industry, the medical device industry and the laboratory technologyindustry. The research questions concerns how this agreement has evolved and theprocess surrounding its emergence may contribute to knowledge about collaborationas a form of organization and the relationship to concepts such as legitimacy,corruption and institutional theory.By tracking the emergence of the current regulatory framework genealogicalthroughout history, the study uncovers how the agreements have played a role in andcontributed to the legitimization and institutionalization of collaboration practices andhow crises have changed the shape of the practices. A theoretical treatment ofrelevant concepts such as legitimacy, institutionalization of practices, corruption andstigmatization of organizations form the basis for an interpretation and analysis of theprocess.The conclusions of the examination of the historical process that led to the currentagreements contribute to empirical knowledge of how crises and stigma affect thelegitimacy of collaboration practices and how the repair of legitimacy can be donesuccessfully after a crisis. The treatment of the empirical material is also a historicalsource for the development of ethics agreements between public health care andpharmaceutical industry and the medical industry in Sweden..

Religiositet och andlighet tycks ha samband med fysisk och psykisk hälsa. I uppsatsen undersöks sambandet mellan andlighet och utbrändhet, två grupper behandlare jämförs och mätegenskaper hos skalorna Spirituality, Religiousness and Personal Beliefs Field-Test Instrument (WHOQOL-SRPB), Spiritual Involvement and Beliefs Scale (SIBS), Maslach Burnout Inventory ? Human Service Survey (MBI-HSS) och Utbrändhet i arbetet (UA) undersöks. Studiedeltagarna var 38 programledare för kriminalvårdens tolvstegsprogram och 39 behandlare i ett psykoterapinätverk inom beroendevården (svarsfrekvens 61,5%). Andlighet korrelerade med personlig prestation (personal accomplishment; r = 0,315, p < 0,05).

När unga behandlas inom ramen för institutionell tvångsvård finns det några aspekter som är avgörande för behandlingsresultatet; att personalen arbetar samstämmigt och i enlighet med relevanta metoder samt att de upprättar en främjande relation till den unge. Det krävs en kombination av dessa aspekter för att på bästa sätt ge den unge förutsättningar att främja sin utveckling. Föreliggande studie syftar därmed till att undersöka hur personal på tre särskilda ungdomshem, drivna av Statens Institutionsstyrelse, ser på metodtillämpning, relationella aspekter och samstämmighet. Studien bygger på en kvantitativ del som innefattar en enkätundersökning där behandlingspersonalen besvarar hur de ser på dessa aspekter, samt en kvalitativ del där institutionschefer, avdelningsföreståndare och annan personal delger sin syn på hur metodanvändning, samstämmighet och relationella aspekter förhindrar eller möjliggör adekvat behandling. Av materialet framkommer att metodanvändningen uppfattas, av personalen, vara ett hinder för de olika verksamheterna.

No infrastructures today are growing faster then communication network. The requirement of being able to communicate in a fast and qualified environment to a low cost increases in line with the development and competition. Itera Networks is no exception when it comes to rapidly developing new and better network solutions for themselves and for their customers. With these requirements in mind their needs for an analysis of the existing communication solution becomes very obvious. This project contains such an analysis in which various studies of the existing network environment have been made.
