Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

A nonsense mutation in the DMRT3 gene has been shown to have a large impact on pattern of locomotion in horses. Horses that can perform several other gaits in addition to the normally occurring gaits, walk, trot and canter, are often hetero (CA)- or homozygous (AA) for this nonsense mutation. Horses that only can perform walk, trot and canter are often homozygous for the wild-type gene (CC). For example the Icelandic Horse is a gaited breed. Five-gaited Icelandic horses can perform both flying pace and tölt, except for the normally occurring gaits, walk, trot and canter, and are often homozygous for this nonsense mutation (AA).

The field trial Exploatering av höga P-AL-tal (Exploiting P in heavily P dressed soils) started in 1982-1983 and included seventeen study sites placed across Sweden. Each site included three treatments, one unfertilized control (A), one aiming at replenishment of harvest removal, i.e. fertilized with 15 kg P ha-1 year-1 (B) and one over-fertilized (C) with 30 kg P ha-1 year-1. In this thesis data from the five longestrunning study sites are analysed based on four hypotheses. The hypotheses stated that in soils with high P-AL values and a pH over 6.0 P-AL will not decrease over time in the control (A) or in the replenishment treatment (B), that P-AL and P-HCl in the top soil will increase at all sites for the over-fertilized treatment (C) and that yields will not decrease as long as the P-AL is above 12 mg P 100 g-1 soil. My conclusions from the analysis of data from the selected sites are as follows: - A pH above 6.0 cannot guarantee a stable P-AL value in an unfertilized but phosphorus-rich soil. - The P-AL of unfertilized soils decreased faster at lower soil pH than at higher pH. - In the replenishment treatment (B) the rate of P-AL decrease seems to fall at a pH of 6.5. However, the influence of the soil type cannot be ignored. - P-AL and P-HCl did not increase in all over-fertilized treatments.

The purpose of this thesis is to examine whether institutional ownership has an influence on CEO compensation in companies where the institutions have invested. In order to fulfil the purpose of the thesis a quantitative study was carried out within the Swedish corporate context where we have studied Swedish institutional investors and companies quoted on the Stockholm Stock Exchange. Our period of study was the financial year of 2007.The empirical questions at issue is; Was there a connection between Swedish institutional ownership and the size of the CEO compensation, and, does Swedish institutional ownership lead to a certain type of CEO compensation in terms of structure?Our results did not suggest that an increased institutional ownership neither leads to a certain type of salary level nor a certain kind of salary structure. These results contradict earlier American research, which has been done within this area and has previously shown a secured connection.The reasons for our results may be many and it is difficult to state any concrete conclusions to why we received differing results.

Bakgrund: Övervikt hos barn och ungdomar är ett internationellt folkhälsoproblem.

This essay includes an osteological analysis on the 1122 scattered human remains from The Pitted Ware culture site at Ajvide, Gotland. The scattered human remains have been found in the cultural layers, during archeological excavations at Ajvide between the years 1983-1987 and 1992-2009, where a burial ground was discovered. During the excavations, 85 skeletons graves were found, with complete and incomplete skeletons of 87 individuals. But aside from the graves, scattered human bones were discovered at The Pitted Ware culture site. One of the aims of the essay was to examine the bone material of the scattered human remains, and to determine whether this could possibly be a different type of burial custom than the skeletons graves.

Lerbodaälven is a river in the municipality of Kil which, due to high phosphorus content is not meeting the requirements for good ecological status according to the Water Framework Directive. The purpose of this report is to investigate the causes for the high content of phosphorus that has been measured in Lerbodaälven between 1995-2010. Four questions will be answered in this report. 1. Does the sewage treatment work affect the phosphorus level in Lerbodaälven? The result from the time series analysis shows that the sewage treatment works have a small impact on the phosphorus level in Lerbodaälven.

The purpose of this study is to gain a deeper understanding of women's violence against men in intimate relationships, get an idea of ??what forms of expression that this type of violence has and to highlight the men's experiences of violence.There is little scientific research in the field in Sweden. Crime Prevention Council has determined that eight percent of all complaints involving domestic violence in 2010, reported by men over 18 years. You can only speculate on how large number of unreported cases is among abused men. The international studies highlight that the abused men feel ashamed of having been subjected to violence by a female partner.I have been based this essay on two theoretical premises, Per Isdal theory of "violence perspective" and Elaine Bergqvist's definition of the suppression technique.The study was conducted through a qualitative content analysis.

This is a study of some risk factors for Diabetes Mellitus (DM) in dogs. As a pilot study it is meant to give information to be used in a planned later, larger and better controlled study. The present study hypothesized that suboptimal feeding (high percentage of homemade and table foods), lack of activity and overweight contribute to the risk of DM. Twenty consecutive dogs diagnosed with DM at the Veterinary University Clinic in Uppsala between 2000 ? 2003 were chosen as the experimental group.

MålsättningAtt utreda skillnader i tillgänglighet till insulinpump mellan olika patientgrupper samt vad som orsakar ett byte till insulinpump.MetodData från 7224 individer med typ 1 diabetes vid tio olika vårdenheter analyserades för att utreda effekterna av njurfunktion, kön, långtidsblodsocker, insulindos, diabetesduration samt ålder. Jämförelsen mellan patientgrupper utfördes med logistisk regression som en tvärsnittsstudie och Cox-regression för att utreda vad som föregått ett byte till pump.ResultatGenom logistisk regression erhölls en bild av hur skillnader mellan patienter som använder insulinpump och patienter som inte gör det ser ut i dagsläget. Cox-regressionen tar med ett tidsperspektiv och ger på så sätt svar på vad som föregått ett byte till insulinpump. Dessa analyser gav liknande resultat gällande variabler konstanta över tiden. Kvinnor använder pump i större utsträckning än män och andelen pumpanvändare skiljer sig åt vid olika vårdenheter.

Social media is by many believed to be the core of a new type of Public Relations. This new PR is called PR 2.0. Most larger companies today are to be find using dif- ferent types of social media to interact with their publics. Each year companies invest more money in this type of digital public relations. Social media is a relatively new online phenomenon and still used at a very early stage.

Advertising is something that we get in touch with on a daily basis and more or less everywhere. Advertising is used in different mediums, such as magazines, television, radio, internet, cellphones et.c. The aim of the present study is to find out if there are any recurrent dissimilarities how advertising is constructed among the mediums regarding rhetorical and semiotical theories. Two different mediums have been chosen for a comparison, printed advertisments versus internetbanners. The study has been based on a total of ten qualitative image analyses.

The purpose of this thesis is to examine the performance of different types of queries in the AltaVista query-based search engine. Thirty information needs have been collected from an ask-a-question service on the World Wide Web, which means that they are based on real users information needs. This is done to avoid partiality in the study. The author has invented different types of queries for each and every one of the information needs in accordance with the search syntax available for AltaVista. The types used are Boolean expressions, queries including proximity operators, phrases and queries directed towards a specific field.

This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.
