Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower
New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.
Mortalitet hos Newfoundland : med fokus på dilaterad kardiomyopati
Dilated cardiomyopathy (DCM) is the second most common heart disease in dogs. Since the disease is seen more frequently in certain breeds, among them Newfoundland dogs, a genetic factor is suspected. This study was partly undertaken to investigate whether there is a significant sex predilection regarding DCM. Moreover, the difference in mean age of death between male dogs and females with DCM was investigated, as well as males and females dying from DCM compared to dying from other reasons (i.e. without DCM).
Är borderline personlighetsstörning en kvinnlig diagnos? : En kvalitativ studie om borderline personlighetsstörning och könsskillnader
The aim of the study is to investigate how clinicians in psychiatric care for adults consider borderline personality disorder to be manifested in men and women, respectively. Could there be a tendency to over-diagnose women and under-diagnose men? In addition, the purpose of the study is to bring clarity to the reasons for gender differences within borderline personality as perceived by the clinicians. The study is based on an inductive approach, in which interviews have been conducted with twelve clinicians working with borderline personality disorders to gain a deeper understanding of how the clinicians consider the manifestations of gender differences.The clinicians described tendencies for women to deliberate self-harm, have mood swings and problems in relations. Men with borderline personality disorders are described as having a higher degree of e.g.

Olika områden olika förutsättningar : En jämförande studie av föreningslivet mellan Danderyds kommun och stadsdelen Spånga-Tensta
This study aims to investigate associations in two areas in Stockholm County with diverse socio-economic conditions. The study intends to examine the impact these differences have on what role the bureaucrats and politicians in the two areas think that the associations should have. Bureaucrats are those who design guidelines for associations and that is why they have an important role in the conditions of the associations. A comparison between the two areas has been made to see if the requirement in the guidelines for the areas are different according to where the members live. The two areas that have been used to compare the guidelines of associations are Danderyd municipal and the district Spånga-Tensta.
"Om vi säger att mobbning inte förekommer i förskolan lurar vi oss själva" : En intervjustudie om förskollärares föreställningar om barns maktrelationer och mobbning i förskolan
The study aims to describe and analyse the relationship between norm and practice regarding social services casework on honour-related problems. The relationship between norm and practice involves the difference between the way it is intended that social workers shall operate in these cases and how they perceive that this works in practice. We interviewed two focus groups of eight Swedish social workers, four in each group. We also held an individual interview with a social services business developer. Focus group interviews were based on two vignettes; one depicting an honour-related case and the second an "ordinary" case.

Breed differences in natriuretic peptides in healthy dogs
Measurement of plasma concentrations of natriuretic peptides have been suggested to be of diagnostic and prognostic value in canine cardiac disease. In several previous canine studies, however, a considerable overlap between investigated groups has been identified. A reliable natriuretic peptide test for use in clinical practice requires establishment of reference values for natriuretic peptides in healthy dogs and cut-off values for subclinical disease as well as for clinical signs of congestive heart failure. Numerous physiological, pathological and pharmacological factors, aside heart function, may influence concentration of natriuretic peptides. A potential effect of dog breed on natriuretic peptide concentration has been suggested but has, to our knowledge, not previously been specifically studied.
Maskulina Miljöpartiet : En studie om nyhetsbevakningen av Åsa Romson och Gustav Fridolin
Problem definition and purpose: A debated question in journalism today is if the mass media have the power to affect norms and values in the society. There are therefore many who believe that the media must works for democratic and equitable news coverage. Studies have shown that there are still many differences in how women and men are being portrayed in the Swedish media, even if Sweden is one of the most equal countries in the world. This inequality may affect the democracy and equality in the society negative.Previous studies have mainly been using gender as the only explanatory factor to explain the difference of coverage between men and women in the news content. The purpose of this study will therefore not only be to compare the coverage of the Green Partys two spokespersons, Åsa Romson and Gustav Fridolin, from a gender perspective but also to take in count other factors that could contribute to differences in the news coverage.Method and material: To find an answer to the purpose of this thesis a quantitative content analysis have been done on a total of 238 news articles in which Åsa Romson and/or Gustav Fridolin occur.Main results: The results of the content analysis show that Gustav Fridolin occurs more frequently in the news than Romson does, and that the articles he appears in is lager than the articles in which Romson appears.
Är korta spenar ett problem i samband med mjölkning? :
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.
Invandringspolitik : Idéanalys om dansk och svensk invandringspolitik
The purpose of this thesis is to analyze equalities/inequalities between the Danish and Swe-dish immigration policy based on Habermas theory about openings/closures and analyze the reasons to the differences between Danish and Swedish immigrant policy. Therefore this study has two question formulations, the first one was "Is there any equalities/inequalities between the Danish and Swedish immigration policy based on Habermas theory of openings and closings?" and the second was "Why are there equalities/inequalities between the Danish and Swedish immigration policy?" The results show that based on Habermas theory there are equalities between the Danish and Swedish immigration policy. On the question why, the re-sults show us that the factors who give the difference are work, people?s attitude to immi-grants and party politics.Keywords: Denmark, Sweden, Immigration policy, opening, closing..
Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :
The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

Private equity - styrning av tre portföljbolag; En komparativ fallstudie av ett buyout-bolags styrning av tre portföljbolag
By identifying effects that a buyout-firm has on management control systems in its portfolio companies, the aim of this thesis is to explain how such effects differs between the companies and finally to explain why the effects differs even though the companies are owned by the same buyout-firm. The study is conducted as a qualitative case study based on interviews with representatives from the studied buyout-firm and three of its portfolio companies.By analyzing the empirical findings with frameworks and theories within management control systems and value creation, we cannot only identify effects that are common for all portfolio companies but we can also observe differences between the portfolio companies.The identified effects that are common for all portfolio companies are: increased internal reporting burden, increased perceived risk of getting laid off among managers and co-workers and replacement of the board immediately after acquisition.The effects that are observed only for two portfolio companies are: increased focus on short-term planning, higher financial targets, replacement of company management upon acquisition and moving of decision authorities to higher organizational levels. Differences are observed although the portfolio companies are owned by the same buyout-firm due to: differences in management and co-workers equity stake in the portfolio companies, differences in business complexity and differences in planned exit-horizon..
