This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.

?Games children play? is a study about the importance of playing with a focus on a group of disabled children. I have made some observations by participating in these children?s play at an accommodation. My interest arouse when I worked as holiday substitute at an accommodation for disabled children.The purpose with the study is to carry out participation observations and look for signs and events that show the importance of children?s play.

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Climate change is expected to increase the frequency and intensity of extreme weather events, with significantimplications for the financial stability of insurance markets. This study analyses how nature-related insurancepayouts and required solvency capital may develop over the period 2025?2099 under three emissions scenarios: RCP 2.6, RCP 4.5 and RCP 8.5, and what this means for the long-term sustainability of insurance as an economic institution. Using Monte Carlo simulation of a non-homogeneous Cram?r-Lundberg model, claimfrequency is modelled as a negative binomial process calibrated against SMHI's climate projections, and claimsizes are approximated by a lognormal distribution fitted to Swedish insurance data (NATY, 2015?2023).The results show that accumulated insurance payouts amount to SEK 96.7 billion under RCP 2.6, SEK 106.0billion under RCP 4.5 and SEK 131.9 billion under RCP 8.5.

Costs of maintenance on combines are a subject of interest thus it constitute a large investment and cost for the individual farmer. Therefore it is important to have up to date knowledge and the right facts to be able to do reliable calculations on one of the largest investments for a farmer. The aim of this study was to compare costs of maintenance on combine/threshingmachine with the computer program for advising environmental issues in agriculture, STANK. Interviews took place and data were collected by handing out questionnaires to 20 farmers. A similar study conducted by Neuman (2003) investigated costs of maintenance and compared these with STANK. The results of this study have also been compared and examined related to data from SLA - Skogs och Lantarbetsgivarförbundet. The result shows that 18 out of 20 combines were given a higher cost of maintenance when using STANK compared to the numbers in this study.

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.

This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations.

Organic material used for biogas production can also undergo other treatments. The emissions and impact from the different treatments are evaluated in this environmental assessment, with a focus on energy and climate. The materials included in the study are organic household waste, slaughterhouse waste and liquid manure. Other than biogas production, the possible treatments for organic household waste and slaughterhouse waste are incineration and composting, and for liquid manure storing and spreading. The analysis is based on data and information from current and relevant literature, and relates to the conditions in the Swedish energy system.

This thesis assignment at C-level is focused on calculation models and prediction methodswhish can be used in the stage we call ?prospecting? of possible windmill locations. Thelocation is southeast of Halmstad at the Farm ?Stjernarpsgods?. The rapport has two mainareas directed towards this task.

Syftet med studien var att undersöka samband mellan lagsammanhållning och upplevt motivationsklimat i fotboll, samt skillnaden mellan kvinnliga och manliga fotbollsspelare i lagsammanhållning och upplevt motivationsklimat. I studien deltog 101 fotbollspelare mellan 15 år och 19 år (m=17.05, sd=0.93) från olika gymnasier med fotbollsinriktning i Halland. Lagsammanhållning mättes med ?Group Environment Questionarie? och motivationsklimat med ?The Perceived Motivational Climate in Sport Questionaire-3?. Studiens resultat visade att såväl positiva som negativa samband mellan lagsammanhållning och upplevt motivationsklimat, samt att män och kvinnor skiljer sig i vissa kategorier av lagsammanhållning och motivationsklimat.

The final thesis ?Hardy palms for scandinavian climate? describes the family Arecaceae both from a general point of view, and with individual descriptions of seven different species that are known for their coldtolerance. The descriptions of each species is brief and the intention has been to give an introduction to some specific species known for their hardiness. Seperate chapters discuss topics as hardiness, pests and other problems and a short instruction for growing palms on open land in scandinavian climate. Finally a short discussion about continued research on this topic and some conclusions ends this final thesis.

This study has been carried out in the spring of 2014 on behalf of PQR Consult AB in Stockholm. The aim of the study has been to analyse the energy usage of the building Skarpövägen 1 in order to explore the possibilites of saving energy by using appropriate equipment. These possible solutions have been simulated by using the programe IDA Indoor Climate and Energy, combined with a life cycle cost analysis. The laundry building, Skarövägen 23, has also been analysed due to its high amount of energy usage. The result of the energy analysis showed that the energy usage was much higher than the energy declaration.

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

In this thesis, input data for energy performance calculations on commercialpremises have been studied. In energy performance calculations, where internal heat gain parameters are unknown, template values that, in a reasonable way represent the activity in the room, are necessary. These values can be used as input data for whole-year calculations, or for calculations on shorter periods of time.The purpose of the Sveby project is to create standardized work practice in energy issues for the construction industry. The work in this thesis is conducted to correlate with the purpose of the Sveby project, with aims of contributing with information and guidelines for the continuing work with commercial premises.In this report, suggestions for template values for internal gains parameters, based on research and calculations in the field are presented. Suggestions on how these can be implemented in a user-friendly way for two energy performance calculation software are also given, VIP Energy and IDA ICE.
