Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

Jag har under detta arbete undersökt hur företaget MAD ELF ART kan arbeta med miljö och sociala aspekter i produktionen. Min uppgift har varit att lokalisera en materialleverantör och producent som kan arbeta med detta på bästa sätt.Under arbetets gång har jag kontaktat flera materialleverantörer och producenter och undersökt hur de jobbar med dessa aspekter. Samtidigt har jag även fördjupat mig i hur man kan ta hänsyn till miljö och sociala aspekter i produktionen, för att undersöka hur vi bäst kan arbeta med det.Vad jag kommit fram till är att materialvalet är det viktigaste och det som skiljer en produkt från att vara en miljöbov och en fara för människor till miljövänlig. Därför har jag i bilagan presenterat en leverantör och producent av materialet 100% silke som är ekologiskt färgad och handvävd. Silke lämnar inget energi-fotavtryck och går att återvinna.

In 1999 the Swedish Parliament decided about 15 Environmental goals aimed to be achieved in time for the next generation. For example physical social planning must be based on programs and strategies how cultural-historical values has been attended, so called programs of cultural heritage. By law the Swedish municipalities are responsible for reaching these goals by creating program of cultural heritage. But only a few of the municipalities have these programs, meaning that many municipalities need to create programs of cultural heritage in the next five years.The aim of this report is to present a model of analysis on programs of cultural heritage in municipalities for preservation and development of cultural environments. By testing the model on the municipalities of Osby and Tomelilla methods on how to create a new program of cultural heritage or how to complete existing documents are formulated.One of the conclusions is that one document, program of cultural heritage, functions as landscape analysis, model of cultural valuation and strategy of developing cultural values.

The purpose with this article is to give examples how to remain and in a long run develop a higher interest in maintenance activities and knowledge. First reason is the changed age-distribution with more number of older employees among maintenance personnel staff and second reason is demand for education due the increasing demand in environmental responsibility.In spite of there is a lot of knowledge of maintenance in national organizations of interests it will not be used in a sufficient extent in many companies. This knowledge is an important base to use to re-built the missing or loosed skills in companies. The national organization UTEK is involved in European projects to validate knowledge of maintenance. Lost of or bad maintenance activities will always affect on the environment.Establish a network between companies is a good way to exchange information in their common business areas.

The municipalities of Sweden have a great responsibility when it comes to adapt the physical planning to a more sustainable development. The development of the society depends upon the growth of new communities and other public services, but to build new communities in a long-term sustainable manner you need good methods and guidance. This study presents four sustainability certification scheme intended to improve and adapt the planning, implementation and performance of new communities and infrastructure project to more sustainable methods based on economic, ecological and social sustainability. These systems are the latest versions of environmental classifications and similar rating schemes, but with a broader focus since they also include the social aspect of sustainability.This study aims to investigate what role sustainability certification schemes can play in local planning for sustainable development. The study compares the certification systems criteria to the tools and goals that the Swedish municipalities have been provided with, to lead efforts towards a more sustainable society.

This is a literature study of learning mathematics in general and algebra in particular. The goal is to explore and investigate the learning procedure and the difficulties pupils have with their understanding. Furthermore, to understand what qualities is requested of pupils in their effort to be successful in mathematics and algebra. I have also explored different pupil thinking styles in mathematics and what consequences that has on their learning and understanding. Moreover, I have investigated some different learning styles and how they can be addressed in teaching of mathematics in general and algebra in particular.

This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

Radon is a hazardous substance that cannot be perceived by our senses. It has long been known that exposure to high radon levels for a long period of time will ultimately cause lung cancer. The Swedish Radiation Safety Authority estimates that 500 people die annually due to this. Although most of them are smokers, even non-smokers suffer from lung cancer caused by radon. The statutory value for radon in homes today is 200 Bq/m³.

The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.

SummaryAt the summer festivals and it?s campsites there are each year thousands of tents left behind. Last year, at the Peace and Love festival in Borlänge, 220 tons of garbage was left behind at the festival area, much of which is tents. 69% of festival goers have at some point left behind a tent on a festival campsite. Many of these tents is purchased very cheaply, for a single festival.

Teachers and special education teachers play a vital role in the creation of a study environment that fosters productivity in students. The current study aims to further expand the knowledge regarding teacher?s perception of common work with developing an optimal study environment within the classroom and the educational institution. In order to achieve this, qualitative interviews have been performed and study results analyzed according Nilholm´s model of the three different perspectives on special education: The critical perspective, the compensatory perspective and the dilemma perspective.The study results show that the concept of order and study environment is not clearly defined among the interviewees. However, the concept appears to presuppose the teacher?s responsibility to create the sense of security and effective study environment to those students who express the wish to educate themselves (Children make the things right only if they have been shown the correct way to do it).

Recent corporate challenges require effective communication in order to secure a company?s reputation. Companies as a result, need to be committed to a series of corporate social and environmental practices along with their financial commitments to their shareholders and investors. In fact, businesses are required to go above their ordinary operations and involve all potential stakeholders that can be affected by their strategies. Companies also need to communicate social, environmental and economic consequences of their activities along with their CSR commitments to their internal and external stakeholders in order to make a better corporate image and improve their market opportunities.

This is a Bachelor?s degree project withthe aim of investigating how to preventwarranty errors in apartment buildings.Our goal has been to compile the mostcommon warranty errors and the reasonbehind them.To achieve this goal, we have studiedthe warranty protocols from fiveprojects. We also performed interviewswith people who work in house productionand people who work with warranties. Thepurpose of the interviews was to findout the underlying causes of warrantyerrors and what one could do to preventthose.Cracks in walls and ceilings were themost frequent remarks on the warrantyprotocols. Remarks on the floors,windows and doors were also common, butnot to the same extent.

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.
