Hur uppnår vi god inomhusmiljö i förskolan idag?
Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power. ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant. As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol. Etanolens framtid vilar på bra lösningar för framställning. I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle. Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.
Stråkröjning och skogsbränsleuttag i unga granbestånd jämfört med konventionella metoder : Två fältstudier vid Asa försökspark
Den här uppsatsen grundar sig på två fältstudier i nyutlagda demonstrationsförsök på Asa försökspark som ska användas i utbildningssyfte. Studie 1 bestod av försöksytor i ett 13 år gammalt bestånd som röjts till samma röjningsförband men med tre skilda metoder; motormanuell selektiv röjning, maskinell stråkröjning och som en kombination av bägge metoderna. Syftet var att beskriva det nuvarande tillståndet, simulera fram prognoser för beståndsutvecklingen och beräkna dess ekonomiska konsekvenser fram till och med första gallring och jämföra de olika metoderna med varandra. Studie 2 bestod av försöksytor i ett 23 år gammalt eftersatt bestånd där fyra olika åtgärder testades; ingen röjning innan gallring, underröjning i samband med gallring, sen röjning och skogsbränsleuttag. Syftet var även här att jämföra de olika metoderna med varandra genom beskrivning av det nuvarande tillståndet, göra prognoser för beståndsutvecklingen och beräkna dess ekonomiska konsekvenser vid första gallring och i den här studien även fram till och med den andra gallringen.
Värmepumpars inverkan på elkvaliten
Modern technology and fast development of heat pumps, the hunt for savings in energy consumption and the strive for environmentally friendly energy sources, convenience, and financial profit, have made heat pumps a reasonable alternative for the heating of houses.When the heat pump starts it will consume a considerable amount of current, which may result in a short-lived voltage-drop if the power grid is weak compared to the start-up current.The company Fortum Distribution which owns and administrates electrical network is interested in an investigation that deals with heat pumps affect on the quality of electricity.The purpose of this investigation is to study fast electrical fluctuations (flicker) as a result of start-up currents for single as well as multiple heat pumps on the same electrical station and from this evaluate whether there will be any problems installing heat pumps..

Delad berättelse ? dubbel glädje! Gruppterapi utifrån ett narrativt förhållningssätt.
During the autumn of 2010 a group of parents met together with two therapist at Mini Maria Hisingen. These parents did have children who had experience of using drugs. This study purpose´s to describe, analyze and understand what has been effective in the work together with this group of parents.The interrogative sentence is; Did we use a narrative approach and what impact did this approach had on the groupprocess? What did the group sessions contribute to the parents and would they recommend other parents to participate in similar sessions? All the sessions were recorded in video. The work was highly inspired by Michael White and his book Maps (2007).
Konstruktion av kapsling till marina navigationsinstrument
Denna rapport är en examensarbetsavhandling utförd vid KTH, Kungliga Tekniska Högskolan, under mars-augusti 2013. Arbetet har gjorts i samarbete med Nexus Marine som är en ledande tillverkare av marin navigationsutrustning för segelbåtar.Syftet med examensarbetet var att utveckla en ny konstruktionslösning för en vattentät kapsling till företagets instrument. Kapslingen skulle gå att öppna och stänga och skruv eller lim skulle inte användas i konstruktionen. Arbetet innefattade inte kapslingens yttre design som skall utföras i ett senare skede. Kapslingen skulle uppfylla de krav som finns uppställda för klassningen IPX7.Nexus Marines navigationssystem och nuvarande sortiment studerades för att ge en bild av vilka funktioner som kapslingen skulle innefatta och i vilken miljö den skulle användas.
"En skola för alla" : verklighet för elever med läs- och skrivsvårigheter och dyslexi?
Many researches have been done about the difficulties in teaching children with disabilities and like in this case dyslexia, which is the disability my essay is focused on. Earlier researches have investigated how and what teachers do practically when they have pupils with dyslexia and what help they have in their work. I wanted to investigate how the theories in National Compulsory School Curriculum (Lpo94) and about inclusive education in relation to the actual work in one Swedish school. My essay, with help of other research, has taken the expression ?school for all? and it?s meaning to what is possible to do in a real life work situation, with the assignments that schools have in Lpo94.
Kvinnor och Medier : En studie om hur tidskriften Glamour konstruerar stereotypa kvinnobilder på sina omslag
Sweden has an active and growing culture of feminist comic book artists that use comedy as a mean of disseminating political ideas and critic. In this essay I do a reparative reading of Sara Granér?s comic book All I Want for Christmas is planekonomi in order to find out if it advocates alternative orders and/or ways of expression. By exploring what the comic book does to me as a reader and how, using the term ?skev? ? a hybrid of queer that examines normativity not strictly tied to sexuality ? and gulesque theory ? a mix of feminism, cuteness, the grotesque and riot grrrl ?, I show that the comic book, through the use of comedy, works as a trojan My Little Pony, reclaiming the girly franchise, while challenging several so-called dichotomies, such as: femininity/masculinity; youth/adult; high art/kitsch.
Las Vegas på Svenska villkor - Att kombinera nätpoker med socialt ansvar
The main purpose is to illuminate how a company links certain values to its brand in an effort to achieve a competitive position. We have done this by studying the government owned company Svenska Spel and its entrance on the netpokermarket. With Corporate Social Responsibility as a guidance for the company they wanted to offer Swedish gamblers an alternative to the, often morally dubious, international actors. Our thesis has taken an internal (corporate) as well as an external (consumer) perspective on the result of this strive. Our conclusions are that although Svenska Spel is successfully integrating social responsibility into their netpokerbusiness, they are facing a difficulty in making the consumer fully appreciate it.

Risks Related to the Maritime Transportation of Oil and Gas (mainly Crude oil, LPG, and LNG) -A Conceptual Study and Empirical Outlook on the Baltic Sea and UK Territorial Waters to Mitigate Risks
Transportation of oil and gas by the Sea characterizes challenges from a safety viewpoint. In this type of transportation, different sizes of special tankers carrying oil and gas. The marine transportation of these scarce natural riches is involved with risks and hazards, which may lead to many losses; for instance, wasting oil and gas, injuries of people, damaging ships and properties, and damaging environment. The main purpose of this thesis is to evaluate the risks, hazards, and accidents during transportation of oil and gas (mainly Crude Oil, liquefied petroleum gas, and Liquefied natural gas) by the Sea with concentrating on transport safety. Hence, a better understanding of these risks and hazards can contribute to decrease of addressed losses.This study is carried out on risks associated with maritime transportation of oil and gas starting with describing the general casual chain (dealing with causes, incidents, accidents and consequences/causalities), continuing with describing risk analysis techniques (including event tree analysis and fault tree analysis) and risk control measures/options, and finally implementing aforesaid investigations on real data from two areas; namely UK territorial waters and the Baltic Sea.In this study, the results of analyzing data from 1991 to 2010 in UK territorial waters revealed that collision and grounding were two most common accidents in terms of crude oil tankers, LPG and LNG carriers in which 44% of all accidents were equally divided between collision and grounding.
"Vi har ju alla en tårtbit i det hela" - en studie om samverkan i arbetet med hedersrelaterat våld och förtryck
This paper deals primarily with the developmental potential and use of court -based mediation in Swedish law, and its relation to court-based conciliation and the judicial procedure as means to end a conflict. In Chapter 42, Section 17 of the Swedish Code of Judicial Procedure, a judge, before the parties have their main hearing, can act as a mediator between the parties to settle the dispute. The judge should, according to the law, always try to make the parties come to an agreement before the main hearing. This obligation can be fulfilled either through the use of court-based conciliation, or court based mediation. Mediation as such is rarely used in Sweden, and one of the goals of this essay is to try to provide a tentative answer to why that might be the case. The second goal is to try to find a consistent, yet flexible notion, of the concept of ?jurisdiction?, and to provide an explanation for the relation between mediation as an alternative method for dispute resolution and the judicial procedure. .
Analys av spänningsstabilitetsberäkningar i det svenska elsystemet
Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.
Trähägn en tänkbar metod för viltskydd i Svenskt skogsbruk?
This survey was made to investigate the possibility of using an alternative method of fencing inSwedish forestry. The most common way of fencing in Sweden today is made by a two meter highmetal net that is attached to turned impregnated poles. The fencing methods that have beeninvestigated is a fencing system made completely out of wood so called ?German wood fence?.Browsing of game in forest regeneration areas is often a big problem and some kind of protection ofthe plants is often necessary. There is several ways of building fences and the most common way isto use metal nets and impregnated poles, this leads to a problem when the fence has profiled itspurpose.
