Nyckeltal för ekologiska fotavtryck för stommar i flerbostadshus

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

Vem i hela världen kan man lita på? : En kvantitativ studie i hur gymnasieelever upplever att de arbetar med medie- och informationskunnighet i skolan

Our society has become increasingly digitized, and all around us information flows constantly. Knowledge about valuing different sources of information, and not least the information itself, are becoming increasingly important. Media and information have come to play a big role in our society, and knowledge of media and information literacy becomes important to learn in school. High school students are at the beginning of their adult lives as educated citizens.In this study, we measured high school students experience of media and information literacy, during their three years in high school. Students answered a questionnaire, with questions based upon theoretical concepts in media and information literacy.

En energiutredning och miljöklassning av Hemsta 12:16

The purpose of this study was to implement an energy analysis and environmental evaluation of the property Hemsta 12:16 in Gävle. Based on two different methods, Energy Balance calculation and Environmental Building, the result of the property's energy use, energy performance and environmental impacts are presented. Except that, measures to reduce final energy consumption are presented.      The proposed measures can reduce energy usage by 100 400 kWh / year, which represents a decrease of 18% of the present energy usage. This would represent a total savings of 63 000 SEK per year. In addition, the environmental performance is improved by adopting the suggested measures..

Nötköttsproduktion i Västerbotten

Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.

Prestionsmått : En granskning av tio välgörenhetsorganisationers årsredovisningar

Background and problemThe biggest difference between companies and non-profit organizations are their purposes. Companies? purpose is to generate profit to the shareholders. Non-profit organizations do not have any shareholders and their purpose is to offer service to receivers of benefits.There are a lot of non-profit organizations today and the competition for the donations is rough. Non-profit organizations can influence the publics? decision of who to support by creating a financial reporting that appeal to the public.PurposeThe purpose of this essay is to examine how non-profit goals are measured in non-profit organizations and if there are a practice on the subject.MethodologyWe choose a qualitative approach as we wanted to understand the reality by explaining it with words.

Effektivare röjningssätt med kedjeröjsågen?

After the mandatory rules for clearing was removed in 1994, the clearing area has increased in Sweden. After the storms Gudrun and Per, the areas became planted with new plants, mainly spruce, but also other tree species. Storm areas are now being invaded by naturally rejuvenated birch in the tilling tracks. Since the birch often is initially growing faster than the spruce it is inhibiting the growth and is also damaging the spruce. The purpose of this thesis is to study the new brush saw with chain and compare it with the conventional clearing saw, mainly in terms of performance and ergonomics. The results show that the new brush saw with chain is very good in almost all clearing operations compared to the conventional clearing saw.

Galoppträning och körning med två travare

The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.

Diversifieringsmöjligheter och deras effekt på avkastning : en jämförande studie av etiska och traditionella fonder

Aim: Based on portfolio theory, which highlights diversification, and CSR, which describes the value of social and ethical responsibility of corporations, this study examines whether there is a difference in risk-adjusted performance between ethical and traditional mutual funds. Ethical funds are limited in their opportunities of diversification and should therefore be limited in their potential perfomance. On the other hand, a focus on social and ethical responsibility can be profitable.Method: The study uses a quantitative approach where we used 25 mutual fund in each category, ethical and conventional mutual funds. The mutual funds and their data has been obtained from www.morningstar.se and www.pensionmyndigheten.se. Historical performance between 2009-2013 were processed to obtain the Sharpe ratio and M2.

Aktivt ägande och lönsamhet i svenska företag

Active ownership is widely regarded as positive for the development and performance of businesses. In this paper, we investigate the impact of ownership concentration and owner identity on return on equity (ROE) in Swedish companies between 1986 and 2008, and show that active ownership might suffer from opposing effects. We find evidence, albeit weak, that ownership concentration has a positive effect on profitability, but that it levels off at high levels of ownership shares. Furthermore, we propose that family ownership has a negative effect on profitability. Our results are dependent of choice of statistical method, but show nonetheless a need to reevaluate what seems to be a universally positive view of active ownership..

Effektmätning i pump

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.

Drivaxeltrycksreglering hos tunga fordon : För en ökad framkomlighet vid vinterförhållanden

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

Incitament för energibesparande åtgärder i den byggda miljön

More efficient energy consumption is essential to secure a sustainable future, not least within the building and real estate sector which answers for approximately 40 % of the EU countries total energy consumption. One part of EU: s work to reduce the energy consumption is the directive on energy performance of buildings which among other things have lead to stricter demands on energy performance in new and renovated buildings.One of the difficulties with making buildings more energy effective is that it often demands big investments and although it results in lower operating costs the extent of these savings and therefore also the repayment time can be difficult to decide beforehand. To make it interesting for property owners and also tenants to invest in energy efficient buildings powerful incentives are needed. Favorable loans to energy efficiency projects are one example of governmental instruments that have been tested in other European countries with good results.Reduced operating costs appear to be the main incentive for property owners to make their buildings more energy efficient. The best result of an energy efficiency project is usually achieved by cooperation between property owners and tenants but in order to make that interesting it is important that both parts can profit from the savings.

Effekten av avståndsoperatorer samt expansion med synonymer med avseende på återvinningseffektiviteten

This thesis examines the effects of proximity operators and query expansion with synonyms on retrieval performance. The queries were expanded with synonyms and structured with proximity operators where the permitted distance between terms varied from 1 to 3. The expansion terms were selected from the online lexical reference system WordNet. Initial query terms were selected from 28 topics that contained compound words and were chosen on the basis of their expandibility. The English morphological analyser ENGTWOL was used for normalization of query terms.

Analys av nivåproblematik i dränagetank på Ringhals 1

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.
