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.

Phytoestrogens are secondary metabolites produced by plants. Among the plants that make phytoestrogens are soya, red clover and some types of grass. The name phytoestrogen is a collective term for compounds such as genistein, daidzein, biochanin A and formononetin. These compounds are similar to oestradiol-17? in their chemical structure.

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

The sites I visit turned into routines a long time ago. Everywhere someone has decided what should be there and what will not fit. I retreat into my daydreams, away from everyday life. A longing for something different, something wonderful. I decided to go where I've never been, searching for something unknown.

Researchers and practitioners have recognized the need for ?transforming? every policy of the company into a competitive advantage tool. Thus, both the pricing approach and the supply chain practices of the firm have emerged as an important determinant of success. In this study, however, we are not only interested in these two aspects, but also in a third one-namely cultural conflicts as an obstacle and challenge. The interaction of the tree factors is extensively presented against the backdrop of Skanska and four of their closest Polish suppliers.

Introduction: On the surgical wards in most hospitals in Sweden patients with different surgical needs are cared for. Patients with gastrointestinal conditions are, for example, nurtured alongside patients with urological disorders or patients in need of observation for head trauma. When the nurse, in addition to these patients, have to care for patients with palliative care needs can be perceived as problematic for nurse and patient alike.Purpose: The purpose of this study is to explore nurses' perceptions of care for patients with palliative care needs on an acute surgical ward, based on a person-centered perspective.Method: A focus group interview was conducted with the strategic selection of nurses from two acute surgical wards in a county hospital in western Sweden. The data from the interview were analyzed with qualitative directed, deductive content analysis with person-centered care as a theoretical framework. The theoretical background shows that person-centered care includes partnership, participation and structured documentation.Results: The results of this study show that even a fourth category, organization, emerged and needed to be reported.

Places like nightclubs or pubs are frequently visited in order to find partners for love, sex and relationships. This study examins behavioral patterns and trends among young adults in these environments. A computer-based questionnaire has been implemented on entertainment establishments - two studentclubs, one youth club and three nightclubs - in Malmoe and Lund in southern Sweden. The emprical material contains at most 149 answers, and at least 109. Sex, love and relationships are less important than expected, but are still some of few big reasons for visiting nightclubs.

Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

The Sand Catcher                                                       The thesis project The Sand Catcher investigates the encounter between permanent structures and an ever-changing landscape. The migrating sand dune Råbjerg Mile in northern Denmark is 40 meters high and moves more than 15 meters every year. By introducing a solid structure on the site, the fast movement of the sand dune is emphasised and thereby our view of time and space.Through intuitively building models with varied openings and densities I investigated how architectural elements react with sand. From these experiments a series of spatial features and effects were found, generated from the meeting with the sand.The Sand Catcher is a solid and permanent structure. The sand is the liquid element that generates new spaces, circulations and experiences.

Varje år i Sverige sker ca 24 000 skallskador på grund av yttre trauma och 30 000 strokeskador. Ett betydande antal får sekundära skador på grund av den ökade vattenhalten kring den skadade hjärnvävnaden. Föreslagen metod är att inducera vattenflöde från skadad till frisk vävnad baserat på teorin om elektroosmotiskt flöde. Teorin bakom elektroosmotiskt flöde är att ett flöde induceras då en spänning läggs över ett medium. Elektroosmotiskt flöde tillämpas i industrin och kallas då electro-osmotic dewatering (EOD).

In 2007 the project with the renewal of the Vasa Park in Stockholm won the Siena Prize. The architects responsible for the project described how they aimed for upgrading the park within its historical framework. Since the project was a renewal and not a restoration of the park, I thought it would be interesting to study how the architects proceeded with this work. The aim of this essay has therefore been to examine how the last renewal of the Vasa Park has chosen to approach the history of the place. To understand the historical development of the park and how the renewal project was carried out, I started with a literature survey consisting of books, the program of the renewal and articles about the project.

Bakgrund: Smärta är ett vanligt problem hos intensivvårdspatienter till följd av kirurgi, trauma, invasiva procedurer och omvårdnadsåtgärder. Sjuksköterskan har ett viktigt ansvar att bedöma smärta och utvärdera smärtbehandling. Bedömningen försvåras av att många patienter har svårt att kommunicera för att de är intuberade, trakeostomerade, sederade, medvetandesänkta och/eller kognitivt påverkade. Flera bedömningsinstrument och publicerade rekommendationer finns tillgängliga, ändå visar tidigare studier på brister i sjuksköterskors bedömning och dokumentation av smärta samt utvärdering av smärtbehandling. Syfte: Att undersöka intensivvårdssjuksköterskors uppfattning om bedömning av smärta hos patienter med kommunikationssvårigheter.
