Nollenergihus i Borlänge : Är det möjligt med biomassa, solenergi och vindkraft?

This report is of technical character and treats how to plan a small building in Borlänge, Sweden.The technical components that have been treated in the report are the construction, foundation,installations and thermic abilities of the house. In addition to planning this house the report alsocontains a part that deepens in net zero energy buildings. The purpose of the report is toinvestigate if the house in Borlänge can be constructed to meet net zero energy buildingdemands.Energy efficient houses such as passive- and net zero energy houses are showing more frequenton the market in Sweden. Ongoing climate changes and growing consciousness about theenvironment in society have contributed to that the environment is a well discussed topic. Toconsume small amounts of energy and at the same time produce local energy is thereforesomething that lies in the future and future houses.

"Du måste helt enkelt äga ditt klassrum" : En studie om lärares ledarskap och strategier i mötet med störande elever

The title, ?You simply must own your classroom?, is taken from a quote from one of my informants.After review of earlier research on how teachers handle their leadership in the meeting with disturbing pupils and which strategies they use to solve problems in the classroom, interesting questions developed. What experiences do teachers have of disturbing situations in the classroom? Which strategies do they use to solve the problems? What kind of support do the teachers consider necessary in teaching? Are there any differences in teachers? experiences and strategies between the two selected schools? The study is supported by earlier research that deals with pupils? and teachers? perspective and strategies in different classroom cultures in terms of norm-breaking behaviour of pupils. The study is also supported by three different theoretical perspectives such as power structure, social order/disorder and support strategies.I conducted the study through interviews with sex teachers who work in the same municipality but in two separate schools.

Enstudie om lågtempererat värmesystem i vägg : -Fokus på inomhusklimatet och energianvändning

Today the human being see energy as a matter of course but the resources that is used for extract energy is today not enough for the world demand. Of all the energy that is used in Sweden today approximately 40 % goes to the building stock. This number will most likely increase if not necessary actions will be made on the already existing building stock since new houses constantly are built which will be added up on the already existing energy supply. This takes cause of action on the already existing building stocks, to fulfill the demands of the future use of energy that has been set by the authority. At the same time the thermal conditions cannot be influenced by the necessary changes that must be made.

Kan sex veckors plyometrisk träning förbättra maxhastighet, hopphöjd i vertikalhopp samt maxstyrka i knäböj  hos unga män?

Bakgrund: Maxhastighet är en viktig faktor inom många idrotter. Olika faktorer som påverkar maxhastighet är anaerob kapacitet, anaeroba energikällor, muskelstyrka samt förmåga att utveckla power. Plyometrisk träning, där explosiva hopp utförs, har som mål att förbättra stretch-shortening cycle (SSC) och power, vilka är viktiga faktorer vid sprint.Syfte: Syftet med studien var att undersöka hur sex veckors plyometrisk träning påverkade maxhastighet, hopphöjd i vertikalhopp samt maxstyrka i knäböj. Studien undersökte även sambandet mellan maxhastighet och hopphöjd samt maxhastighet och maxstyrka. Den här studien är viktig då ingen tidigare studie till vår vetskap har undersökt hur plyometrisk träning påverkar maxhastighet, hopphöjd och maxstyrka.Metod: Tre test användes för att mäta maxhastighet, hopphöjd samt maxstyrka.

VIBRATIONSSKADOR - FÖREKOMST OCH FÖREBYGGANDE : Analys av ett strukturerat arbetssätt inom bostadsproduktion

Ask any constructional worker and there is a high probability that this person knows a colleague with pain or other disorders caused by working with power tools.According to the Swedish Work Environment Authority 71 percent of the Swedish constructional workers is exposed to vibrations at least 25 percent of the working hours. Despite this, the number of reported occupational sicknesses caused by vibrations is as low as 1, 4 percent.JM Ltd. is one of the largest constructional companies in Sweden. Their main business is new housing and development of residential areas. God quality and low impact on the environment is a part of great importance in the company?s long-term goals.

Doby?ins fokus : Detaljerna och debatten om Gud i ?urkina rodnja

Nathan Söderblom, Swedish archbishop 1914 - 1931, understands his role as bishop from an integrated theological conception that episcopacy is a gift to the church and the apostolic succession a heritage of utmost value. Episcopacy is an important tool to make the churches come together. in his work for peace during the Great War it was through his position without any power that he could approach the politicians. His calling was not only for Sweden; he had a responsibility for the whole world. In the Ecumenical Cope for the 1925 Stockholm meeting Söderblom expressed his views on the importance of the Uppsala see.

Energieffektiv torkning av kläder : en studie av torktumlare med varm- respektive kallvattenanslutning

Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.

Direct-EGR tillämpat på HCCI

The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Utveckling av elektronik och solpanel till portabel solcellsdriven lampa

Syftet med detta projekt har varit att utveckla en solpanel och elektroniken till en portabel solcellsdriven lampa. Huvuddelarna i systemet är en solpanel, en ljuskälla, ett batteri och ett USB-uttag för att användaren ska kunna ladda t.ex. en mobiltelefon. Målet har varit att leverera produktionsunderlag för en färdig slutprodukt.En solcell är en halvledare som direkt omvandlar solljusets energi till elektrisk energi i form av likström. Den spänning och ström som alstras av en solcell är beroende av ljusinstrålningen, temperaturen, cellens effektivitet och belastning.

Passivhus av helväggselement i träull

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

En karneval går inte att stoppa! : En designpedagogisk undersökning om barn och normer

A carnival can not be stopped! A design pedagogical study of children and norms In Basel, the only Protestant carnival in Europe takes place. The carnival is called Fasnacht. For three days, there is a wild and uninhibited play with tradition, crossing borders and social criticism.The aim of this thesis is to expand the understanding of the concept of the carnival, and how to use it for an educational purpose. Three children from Basel have been involved in an workshop where they designed and talked about norms and power structures through the carnivalesque principle. The study is based on the questions: How can you use the carnival as a starting point for designing and talking about norms and power structures together with children? And; How can the design process support such a project? To spot this, I made arrangements for a design educational project.

Cow power : hållbar mjölkproduktion i framtiden

För att få mjölkproduktionen mer hållbar och göra den till en naturlig del i samhället samt att integrera den med miljön i största möjliga utsträckning har en projektgrupp på Wageningen Universitet i Nederländerna fått i uppdrag att göra en lösning som innefattar detta. Detta genom att se produktionen från olika synvinklar och inte använda traditionell filosofi när det gäller stallbyggnader för mjölkkor samt genom att se på alla inblandades faktiska behov. Projektgruppen har studerat kons, lantbrukarens, miljöns och även allmänhetens behov och utefter det skapat prototyper på mjölkgårdar för att göra produktionen mer hållbar.Projektet har döpts till Cow Power, som till svenska kan översättas som Kraften från kon. För att få bättre insikt i projektet kontaktade vi universitetet som bjöd in oss med varm hand. Redogörelsen av projektet grundar sig främst på det material som sammanställts av projektgruppen samt personliga samtal vi hade med de som var involverade i projektet vid vårt besök på Wageningen Universitet.

Trettio år av jämställdhetspolitik : Från kvinnor i arbete till jämställdhetsintegrering

Thirty years of gender equality politicsFrom women?s work to gender mainstreamingThis Bachelor thesis examines how the Swedish state has practiced gender equality as a political project during 1972 until 1999 through the budget bills, using a ?What?s the problem represented to be?? approach aiming to uncover which discourses policies are based on. The method also studies what assumptions underlie policy problems, what is left as unproblematic within the policies and what effects are produced by specific problem representations. A central question for the thesis is what has remained and changed within Swedish gender equality politics. The history of the Swedish welfare state is presented as a background on how gender equality policy has affected the everyday life of women and men.

Bergerosion i utskovskanaler

Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.
