Småskaliga vindkraftverk på byggnader i urban miljö : Möjligheter och hinder för ökad implementering

Intresset för småskaliga vindkraftverk på byggnader har ökat under de senaste åren. Allt fler människor blir mer energi- och miljömedvetna samt ser fördelarna med att elektriciteten produceras där den konsumeras; i den bebyggda miljön.Det är dock en större utmaning att installera ett vindkraftverk i urban miljö, jämfört med i öppet landskap, då det finns många faktorer som skall beaktas. Stadens komplexa uppbyggnad gör att vindens hastighet och riktning varierar och ger upphov till turbulenta strukturer i den omgivande luften. Många av dagens vindkraftverk kan ej operera effektivt vid turbulens, därför måste dessa vindkraftverken placeras på höga höjder för att nå den laminärt strömmande vinden över staden, vilket ger orealistiska längder på de master som krävs, även om vindkraftverket monteras på en byggnad. För att kunna utnyttja de vindar som uppkommer i urbana miljöer bör vertikalaxlade vindkraftverk med en helixformad geometri på rotorn användas.

Sample cradle prevents pre-analytic error on platelet counts but is not essential for hemoglobin measurement and prothrombin time

Introduction: It is recommended to place all the vacuum tubes directly on a sample cradle after vein puncture to prevent analytic error. This recommendation is not always easy to follow because the samples are taken by different professionals under different situations.  The three most common analyses, platelets count, haemoglobin and prothrombin time were tested.  Therefore, it was interesting to compare results from the three most common analyses with or without sample cradle, to evaluate the influence of this step on the result. Methods: Three analyses were preformed, using blood from 50 different persons. Each person gave two vacuum tubes, each contained 4.5mL of venous blood for the study.

Trädslagsinverkan på markvegetationens utveckling i odlingsförsök med tall och contorta :

In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.

Utveckling av en äldre villaträdgård : från oplanerad till planerad

The result of this work is a plan for the development of an 1128 m2 elderly raised garden. The purpose has been to create an overall plan covering the long-term development of the garden. The work process has covered a description of the garden of today, review of requirements, analysis of the garden sections, design of a new plan as well as starting the construction of the new garden. The plan covers a time period of a couple of years to create the new garden since the construction work is carried out during spare time with small resources available. The planning must contain review of functions such as protection from insight, eating area and compost area. Also the esthetic expression must be planned. Colors, shapes, choice of material and plants together make up the esthetic expression. It is recommended to include anything you wish to create in the garden. In a raised garden one has to overcome the step to remove trees and shrubs and think different.

Balancing packaging complexity by introducing platforms - A study at Carlsberg Breweries

Many consulting firms offer tailor-made solutions within complexity management, but these are not general frameworks built upon theories. Carlsberg are dealing with a large complexity within their one-way glass bottles, as they are growing by acquisitions, and are not attained enough economies of scale. This thesis balances the packaging complexity, with platform theory as a foundation. Twelve platforms were developed at Carlsberg, containing 21 bottles, and the calculated savings potential for applying these are EUR 28,9 million..

Karlskrona: örlogsstad och världsarv : en fallstudie om stadsidentitet

In 1998, 'the Naval Port of Karlskrona' was inscribed as a World Heritage Site by UNESCO and thus, it is equally protected as China?s Great Wall and the Pyramids of Egypt.The essay is a case study of Karlskrona, one of Sweden's most well planned cities, where famous urban planners and architects such as Erik Dahlberg and Nicodemus Tessin the Elder has been involved.Today, Karlskrona is a rather unknown small town in Sweden's outskirts, where population growth has been a problem. When Karlskrona was founded, in the late 17th century, Sweden was a major power. The Blekinge archipelago was in the middle of the Baltic dominion and Karlskrona represented a midpoint in the kingdom. Therefore, Karlskrona has a small town charm with the history and style of a cosmopolitan city.By initially studying how the town?s character of today is expressed, the history of Karlskrona is explored.

Hur påverkar inavel fruktsamheten hos häst?

Inbreeding has become a problem in some horse breeds. Studies show that it may lead to inbreeding depression which affects e.g. reproduction traits. In the wild there are mechanisms that make horses avoid mating with close relatives. When selection is done by humans this mechanism is removed and intensive breeding for a few traits, for example good racing results, can become a problem.

Upplevelse av delaktighet hos vuxna med lindrig utvecklingsstörning

Levnadsvillkoren för individer med utvecklingsstörning har under de senaste decennierna förändrats till det bättre. Att känna sig delaktig i sitt liv och ha möjligheten att själv påverka livssituationen är viktigt för dessa människor. Uppsatsförfattaren ville med den här studien undersöka om skillnad finns i hur aspekter av delaktighet uppfattas av två grupper; individer med utvecklingsstörning och personer i deras omgivning. En enkätstudie genomfördes med en omarbetad version av ?The Arc?s Self-Determination Scale? (Wehmeyer, 1995).En rangkorrelation visade på samband mellan vissa frågeområden.

Biomass losses during short-term storage of bark and recovered wood

Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).

Hästar i skrämmande situationer : en jämförelse mellan hanterad respektive fri habituering

In connection with riding and handling of horses, many accidents that can cause severe injuries to both horses and humans are existent. The cause is in most cases that the horse is frightened. The horse's fear also affects its usefulness and it has been shown to have adverse effects on the horse's welfare. To increase safety and improve the welfare of both humans and horses, it is important to find appropriate training methods to reduce the fear of horses in frightening situations. This experimental study compares handled habituation to free habituation.

Implementation of a Data Handling System for a Scientific  Magnetometer on a CubeSat

Since their invention in 1999, CubeSats have become a widespread standard for small picosatellite missions. CubeSats allow for quick development of satellite payloads and launch in space without the high costs of a normal satellite. Emphasis during the CubeSat design process is placed on use of commercialoff- the-shelf (COTS) components and reuse of previously-designed units.This report describes the interfacing of a scientific magnetometer, the Small Magnetometer in Low-Mass Experiment (SMILE) to such a CubeSat mission, the Space Weather using Ion spectrometers and Magnetometers (SWIM). Design of a complete platform for use in multiple such missions is presented here.Modularity is one of the key aspects followed in the course of the work. A new board containing the analog pick-up and compensation circuitry for SMILE has been designed to fit inside a CubeSat frame.

Sjuksköterskestudenters attityder till personer med HIV : en enkätundersökning

Bakgrund: HIV/AIDS är idag en sjukdom som varit känd för oss i snart tre decennier. Synen på människor som har HIV har förvisso ändrats. Trots förändringar upplever personer med HIV fortfarande negativa attityder, diskriminering och socialt utanförskap både ute i samhället och inom sjukvården. Vid en närmare granskning av litteraturen visar det sig att attityder och rädslor finns kvar mot personer med HIV även hos sjukvårdspersonal. Syfte: Att undersöka sjuksköterskestudenters attityder till personer med HIV.
