Syftet med studien är att få ökad insikt i körledares förhållningssätt till och hantering av sångtekniska övningar i kör. Bakgrundskapitlet beskriver sångrösten som instrument, och olika ? i sångsammanhang ? vanligt förekommande begrepp samt ger en presentation av tidigare litteratur och forskning som anknyter till studiens syfte. Vidare presenteras ett sociokulturellt perspektiv i egenskap av teoretisk utgångspunkt.Undersökningen är genomförd med hjälp av den kvalitativa intervjun som metod. Fyra i nuläget aktiva körledare intervjuades och i resultatet beskrivs deras syn på vad röst- och sångteknik innebär och hur de går tillväga för att förmedla detta till sina korister samt vilka redskap som används för ändamålet.

Phytoremediation is a technique using the ability of plants to absorb pollutants in their biomass from contaminated soils and remediate it. The plants are then harvested and the soil gets purified. This method is more environmental-friendly than the normally used methods for soil remediation. Glasriket in Småland is an area with large amount of pollutants including arsenic, cadmium and lead. This area must be cleaned from these metals because of the high threat to the environment ant the health of people who live here.

This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters.

Semantic feature analysis (SFA) is a treatment technique used foraphasic word finding difficulties after stroke. The method has earlier beenevaluated with positive outcome regarding words that have been trainedduring intervention while more varied results have been presented regardinguntrained words. The aim of this study was therefore to evaluate the effectsof the method on naming in untrained nouns and verbs, in both confrontationnaming and in discourse. The present study is the first to evaluate SFA withSwedish-speaking persons. A single-subject design was used.

How can we use modern X-ray technology to raise awareness of the information that is hidden in historic upholstery? The materials and techniques add information to the history object in question and  about a profession that is sparsely documented in our country. The knowledge we have today has largely been obtained by studying damaged upholstery, or by removing the show cover and upholstery, a technique which involves high risk of damaging the upholstery. X-ray technology offers  a non- intrusive way to examine historical upholstery.Through case studies, I examined four artefacts. The artefacts went trough an inititial visual exam before being transported to The National Heritage Board in Visby where they underwent a thorough X-ray exam.

This candidate thesis concerns the ?all but forgotten? material from the bronze age site named ?Raä 977, Hansbo 1:3, Vojmsjön, Vilhelmina?. During 1975-76, an archaeological dig was carried out by Västerbottens museum led by Ulla Walukiewich in an attempt to preserve the information the site held, before it was destroyed by the erosion brought on by the recently regulated sea ?Vojm? (Vojmsjön). The archaeological dig yielded a stunning amount of finds, samples and information previously unknown.

Kommunala förskolan förutsättningarna har förändrats i och med införandet av nya styrformer som brukar sammanfattas under namnet New Public Management. Kraven på de anställda har ökat liksom stress och arbetsrelaterad psykisk ohälsa. Arbetspsykologiska stressmodeller förklarar stress utifrån olika antaganden om obalanser mellan t.ex. krav och resurser eller krav och kontroll. Den här studien syftade till att undersöka konkreta upplevelser av arbetsstress hos förskollärare i den kommunala förskolan.

The amount of electricity is limited in Namibia and the large distance between towns andvillages complicates the energy supply in the country. Therefore an alternative way to provideaccess to appropriate energy technologies is needed. The Government of the Republic ofNamibia (GRN) has adopted an approach of helping off-grid households by establishing EnergyShops in each region in Namibia and these shops are going to sell basic renewable energy andenergy efficient products. The Renewable Energy Efficiency Institute in Namibia (REEEI), theinitiator of this thesis, is coordinating the establishment of these Energy Shops.The main purpose of this thesis was to examine the needs of energy products for the Namibianpopulation and develop an assessment method for the Energy Shop in how to select appropriateenergy products already on the world market. The purpose was also to develop a method forchoosing an Energy Shop.

The rising demand for electricity and heat raises a big challange for the society and engineers. Many products have been introduced to the market to supply more energy to the energy systems. Absolicon AB is a Swedish company that develops and markets a combined heat and power generating product. The product, Absolicon X10, uses a parabolic trough to concentrate the radiation of the sun onto a receiver. The receiveris equipped with mono crystalline solar cells and is cooled by a circulating liquid media.

Arbetet behandlar sättet att sjunga folkvisan från bondesamhället till modern tid. Mitt syfte är att ta reda på om sättet att sjunga folkvisan har förändrats genom åren, vidare vill jag undersöka hur folksången har förändrats och vad det beror på. Jag har intervjuat fem kvinnor som alla är verksamma folksångerskor, använt mig av litteraturstudium och lyssnat till arkivinspelningar. I mitt arbete har jag kommit fram till att folksången har förändrats under årens lopp. En skillnad som blev tydlig för mig är att sångarna förr generellt sjöng på ett mer osentimentalt sätt och att sångarna i dag ofta lägger större vikt vid att tolka texten och att de drillar mer idag.

I dagsläget har världen en stadigt växande befolkning och där igenom en stadigt växande energiförbrukning. Med en växande energiförbrukning har det under de senaste åren uppenbarats diskussioner rörande samhällets hållbarhet och miljöpåverkan.  Samtidigt sker det en kontinuerlig teknikutveckling och människan är mer beroende av konstant elförsörjning än någonsin tidigare. Teknologiska framsteg, tillsammans med önskan att sträva mot ett mer hållbart samhälle med hög elleveranssäkerhet, har mynnat ett begrepp kallat smarta elnät.Till följd av att elnätet involverar en stor bransch råder det delad mening över vad som utgör ett smart elnät. Detta har lett till uppkomsten av olika definitioner och modeller av konceptet. I syfte att skapa en övergripande uppfattning har en litteraturstudie utförts för att sammanställa de huvudsakliga områden som utgör det smarta elnätet.

This thesis is a study of residential environments and a design concept for a proposed housing area in Tierp. The industrial era created a need for the central planning of housing. The confined environments that arised in cities during the 19th century, together with modernistic and democratic ideas, led to regulations in planning and housing. Though the overall goal has been the same: to create a good standard in living, the ideas of how to achieve that have varied. The starting point for following generations has been to attend to the insufficiencies of the earlier planning periods.

In this Bachelor thesis, we examine how the work of the librarian has changed over the past three decades. The research questions focus on the changes in librarians´ roles and working tasks regarding factors like technique, meetings between librarians and visitors and also how to give service to visitors.We have conducted interviews with librarians at university libraries as well as public libraries. In all, there were four interviews. We have also compared the two types of libraries.We have looked closely at these factors: the tasks of the librarians, the skills needed, how the library has been used as a democratic arena, and what kinds of meetings there are among librarians and users of the library. From these themes we have created interview questions, and our analysis is structured according to the themes.We have worked from a theory on different kinds of identities within the profession.

A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

In today?s horse keeping, there is an increasing awareness of the importance of movement and activity for the horses comfort and tenability, while tradition has it that horses should be kept in boxes and small paddocks. In order to develop housing systems that fulfils and optimizes the horses needs regarding movement and activity, we need to know more about factors that influence the activity patterns of horses. A first step is to be able to record and analyze the gaits in horses with an automated system. This could be done by use of accelerometer data.In this pilot study, existing accelerometer technique was used to characterize the different gaits in horses (walk, trot and canter) by studying how their respective signal patterns differ and how this is influenced by the size of the horse.The accelerometers being used in this study measures the movement in three different spaces; horizontal, lateral and vertical.
