In this thesis a method for evaluating investments in small scale hydro power is presented. An analysis of the future position that small scale hydro production will have on the Nordic electricity market is also carried out. This is done by an inventory of technology and economic and environmental aspects. The inventory is also a guide as to how the project should be implemented.Hydrolyzer is the name of the Excel tool developed to evaluate investments. The tool requests input data from the user and then evaluates the investment and generates a sensitivity analysis.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Syftet med arbetet är att undersöka hur lärare resonerar kring hur de arbetar med formativ bedömning och individanpassad undervisning i matematikundervisningen i grundskolan. Vi har därför undersökt detta område närmare genom en empirisk enkätstudie. Vårt urval har bestått av respondenter som dagligen möter denna problematik och som har erfarenheter inom området d.v.s. grundskollärare. Hälften av respondenterna hävdade att de individanpassade matematikundervisningen i stor utsträckning, resterande i måttlig eller liten utsträckning. Gällande frågan om formativ bedömning svarade omkring hälften av respondenterna att implementeringen av formativ bedömning sker i stor utsträckning och resterande i liten eller måttlig utsträckning.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

A unified model of stress and affect consciousness was proposed. The connection between affect consciousness and perceived stress was studied. Teachers (n = 19) were interviewed using Monsens affect interview, followed one month later by a questionnaire containing Perceived Stress Scale (PSS), State-Trait Anxiety Inventory (STAI-S, STAI-T) and Twenty Item Toronto Alexithymia Scale (TAS-20).Statistical analysis showed no connections between level of total affect consciousness and perceived stress. Though there were some indications of a negative relationship between affect consciousness and trait anxiety. There were also indications, using a complementary analysis, of a connection between level of affect consciousness on the subscale distress in the interview and perceived stress.

Praktiskt arbete inom institution innebär kontinuerliga riskbedömningar och beslutsfattande av eventuella åtgärder. Denna studie syftar till att undersöka vilka uppfattningar och resonemang personal vid två särskilda ungdomshem har kring risker och riskbedömning samt vilka beslutsstrategier som tillämpas. Vidare undersöks skillnader i bedömning ur ett genusperspektiv. Kvalitativ metod tillämpas och studien omfattar tolv intervjuer. Resultaten visar att risk och riskbedömning uppfattas som mångdimensionella begrepp omfattandes samtliga aspekter i det dagliga arbetet, dock förekommer interindividuella skillnader utifrån kunskap, erfarenhet och personlighet.

Cambodia, in Southeast Asia, has tropical monsoonal climate with distinct dry and rain seasons. Many people are poor and live in rural areas. Farmers mainly culture rice, and raise pigs, cattle and poultry as well. During two months, a minor field study was performed in Cambodia. The main purpose was to evaluate the impact of contributions done by projects that started in 2005 and were managed by the local organization CelAgrid.

Syftet med studien var att ta reda på om det går att predicera medarbetares livstillfredsställelse, psykosociala välmående och upplevd relation till närmaste chef utifrån chefers emotionsperception och emotionsreglering. Detta gjordes genom att 38 chefer utförde ett datorbaserat emotionsperceptionstest samt besvarade Emotional Regulation Questionaire. Deras närmaste medarbetare bestående av totalt 213 stycken fick sedan besvara en enkät bestående av delar från Satisfaction With Life Scale, SF-1 och QPS Nordic. Studiens huvudresultat visade att generaliserat kan resultatet från emotionsperceptionstestet och det självrapporterade användandet av omvärdering av känslor hos chefer förklarar 28 % av skattningarna på Satisfaction With Life Scale hos medarbetarna. Resultaten diskuteras i termer av att chefer skapar en positiv atmosfär på arbetsplatsen, identifierar sociala problem och löser konflikter effektivare när de är skickliga på emotionsperception och omvärderar sina känslor..

HiGtech är en projektgrupp på Högskolan i Gävle vilka konstruerar och bygger energisnåla tävlingsfordon. Ett av fordonen tävlar i Shell Eco Marathons prototypklass för bensindrivna förbränningsmotorer och drivs av en på högskolan konstruerad motor. Motorns effekt överförs till en kedjetransmission via en inköpt och modifierad centrifugalkoppling. Den nuvarande centrifugalkopplingen väger cirka 1,5 kg. Då en stor faktor för tävlingsresultatet är fordonets rullmotstånd, vilken beror av fordonets vikt, har målet med detta arbete varit att konstruera en specialanpassad centrifugalkoppling, vars vikt endast är hälften så stor som motorns nuvarande koppling.

AimThe purpose of this study has been to examine attitudes towards dance in a broad sense, among Swedish schoolchildren. The study has been done with three different questions in mind: What do pupils think and express about dance? Are there any differences in attitude towards dance between girls and boys? And how do the pupils relate to gender conceptions in connection to dance illustrations?MethodEight pupils 12 ? 14 years of age have been interviewed separately during physical education lessons. During parts of the interviews dance illustrations were used in order to encourage the pupils in their discussions, especially when asked to relate to dance and gender conceptions. The statements have been interpreted from a gender theoretical perspective.ResultsMy interview study shows that male pupils to a larger extent than female pupils inhabit hostile feelings towards dance as part of physical education lessons.

Sweden has a long and extensive wind band tradition. Today the interest for the traditional instruments is decreasing among children and teenagers. What can this be due to? Which conditions are needed for a functional wind band in the future? The purpose of this essay is to find answers to these questions and at the same time shed light on good examples, where the wind band activity works. To be able to answer the questions have I made four interviews with persons who have a big knowledge and interest about the subject.

The aim of my study is to answer the question whether there is a potential for services by working horses in the Swedish municipalities. The Swedish University for Agricultural Sciences (SLU) and Swedish Farmers Union (LRF) has started a cooperation called Climate School (Klimatskolan), with the purpose to increase knowledge in environmental and climate related issues in context of agriculture. This Master thesis is in the framework of the Climate School.Global warming is a problem that gets much attention today. Global warming and climate change are two subjects that are very much in focus on the political agenda. The municipalities of Sweden have a big responsibility concerning environmental work and to develop their own environmental thinking.

Social fobi är en av de vanligaste ångestsjukdomarna. Rädsla och oro i sociala situationer och prestationsrelaterade dito är utmärkande för dessa individer. Social fobi tenderar, om den inte behandlas, att bli kronisk och det finns indikatorer på att tillståndet förvärras över tid. Idag finns behandlingar som ger goda utfall direkt efter avslut, men huruvida behandlingseffekterna håller i sig över längre tid är mer höljt i dunkel. Internetadministrerade självhjälpsbehandlingar har en möjlighet att öka tillgängligheten för denna klientgrupp och det är då av vikt att den är av god kvalitet.
