Though still well used in Swedish schools, textbooks are no longer under any governmental control or inspection. It is now responsibilities of the teacher, thus, knowledge is considered crucial. Therefore, the aim of this study was firstly to investigate if and how four biology/natural science textbooks, produced 1957-2008 for primary school years (3) 4-6, expressed any sex, gender and/or sexuality norms. Moreover, due to thoughts of queer theoretic Judith Butler, the study also investigated if and how these three norms interacted. By examining what the textbooks mediated, the purpose was finally to find out if and how the norms differed or not.

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.

The purpose of this work is to study a circulation project in Enköping municipality, where the society?s rest products are used to make beneficial products. In Enköping the rest products from waste treatment plants and private sewers are used to fertilize and irrigate Salix plantations that later are harvested and burned at the local combined heating and power plant, ENA Energy AB, to produce electricity and heat. Possibilities to apply this kind of project ona municipality in Russia are also explored.Guryevsk municipality in Kaliningrad region was chosen since there is a need to improve energy systems and reduce emissions to water and air. This municipality strives to become environmentally friendly.

In Sweden, a big part of the energy use is used in the housing sector. Political goals and targets are set up which the housing sector needs to work towards. Apartment buildings are a major part of the housing sector in Sweden and therefore reduction of energy use in these kinds of buildings are key to lower the energy use in Sweden. But there are not only political incentives to reduce the energy use. Some energy?saving measures are directly profitable and should thus be performed.

Målet med examensarbetet är att utveckla en marknadsplatsapplikation för Android. Marknadsplatsapplikationen ska tillhandahålla funktioner för att ge användaren förutsättningar att hitta och ladda ner applikationer över Internet ifrån marknadsplatsens serversida. Marknadsplatsapplikationen kommer likt en tunn klient vara helt beroende av innehåll från en serversida. Vid examensarbetets utförande existerade dock ingen serversida då denna ännu inte var färdigutvecklad.För att utveckla marknadsplatsapplikationen utan närvaron av en serversida, implementerades en emulerad serversida som utåt sett hade funktionaliteten av en framtida serversida. En mjukvaruarkitektur implementerades bestående av tre lager: användargränsnitt (GUI), kärnfunktionalitet (Core) och webbkommunikation (WebCom).

The aim of this paper is to describe, visualise- and analyse media’s discursive representations of female politicians in Swedish printed media. The focus of the analysis is to show if, and how these images can be understood and interpreted in terms of a socially constructed gender stereotyped suborder. The paper takes it's theoretical and methodological departure in the discourse analysis, which is combined with feminist political theory. Feminist political theory is concretised in the use of what Yvonne Hirdman calls the "gender system" which arranges the sexes into their respective genders and is based upon two rules/principles/logics: 1) the rule of distinctive separation, and 2) the male norm. Closely related to the aim of the paper lies also the critical theoretic assumption that people has to be aware of their own part in the production and reproduction of the discourse in order to change make a change.

Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..

Syfte:Att på den svenska marknaden undersöka effekten av resultatmanipulering, efter införandet av Svensk kod för bolagsstyrning. Metod:Kvantitativ datainsamling använd's för att utföra regressioner del's för beräkning av EM, del's för identifiering av signifikanta förklaringsvariabler. Informationen hämta's bland annat från årsredovisningar, SIS Ägarservice och Datastream. Studien har en deduktiv ansat's. Teoretiska perspektiv:Ett antal bolagsstyrningsteorier har behandlat's rörande agentprincipalförhållanden, institutionellt ägande samt separation av ägande och kontroll.

I denna uppsats behandlas hur klassningssällskapens regelverk kan bidra till ett örlogsfartygs överlevnad vid vapenverkan. Syftet är att undersöka om regelverken kan användas för att implementera stryktålighet genom sina notationer och krav på redundans, separation och skydd mot splitter.Arbetet inleds genom kunskapsuppbyggnad av teorier som behandlar örlogsfartygs överlevnad, vilka sedermera bildar arbetets teoriram. Sedan sker en analys av regelverken samt en fiktiv operativ miljö skapas för att ta fram taktiska uppgifter samt hot, vilka sedan omvandlas till verkansdelar och kritiska system. Därefter skapas modellerna som tillsammans med verkansdelarna används i simuleringen som genomförs i simuleringsverktyget Semiautomatsikt fartygs verktyg för AVAL. Simuleringarna mäter utslagssannolikheter av olika funktioner ombord vid påverkan från de framtagna verkansdelarna.

Syftet med uppsatsen är att fördjupa kunskapen om och förståelsen för processen från delaktighet i en dysfunktionell familjesituation, präglad av en familjemedlems missbruk, till separation, frigörelse och integritet. Utifrån detta syfte ställdes frågorna: Hur upplevs processen från den påverkan som det innebär att leva tillsammans med en alkoholist till att frigöra sig och hitta sitt eget sätt att leva och hur kan man utifrån symbolisk interaktionism och teorin om spegeljaget fördjupa förståelsen av denna process?Som metod har används kvalitativ intervju med en kvinna som har levt med en alkoholiserad man. Uppsatsen belyser frågorna ur en social synvinkel och utgår från det teoretiska perspektivet symbolisk interaktionism som sätter fokus på interaktionernas betydelse. Teorin om spegeljaget visar på betydelsen av andras spegling för människans självbild.Uppsatsen kommer fram till att kvinnans liv på ett genomgripande sätt har påverkats av att leva i en relation med en man som missbrukar alkohol.

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Odling av mikroalger för framställning av biogas är ett relativt outforskat område. Den forskning som hittills utförts har påvisat lovande resultat tack vare möjligheten att utnyttja resurser som idag går till spillo, eller till och med utgör miljöproblem; mikroalgerna kan rena både näringsrikt vatten (exv. avloppsvatten) och koldioxidutsläpp (rökgaser från industrin) då de tar upp föreningar innehållande kväve, fosfor och kol från dessa källor. Den producerade biogasen kan ersätta fossila bränslen. Dessutom skapas en rötrest som kan återföras till odlingsmarker vilket sluter näringskretsloppet.

Within all industries, there is a change in working time required; this also includes the construction sector. However, the way construction sectors are differentiated is by not having been given the opportunity to be practiced or tested.  The aim of this thesis that we have done in collaboration with the Concrete Industry was to investigate the possibility of developing an automated method for quality assurance of SKB at the site. The idea is to make the O-funnel to be more utilized and therefore ensuring that the appropriate concrete quality is provided which eventually would lead to a better development in the production process.The project has involved theoretical work and laboratory experiments. The theoretical work gave us a good foundation at the beginning of the project. After gathering the information and material, the laboratory experiments began by SCC in their laboratory in Hammarby. The collected data from the various laboratory tests formed the foundation for trying to relate measurements for consistency of SCC with each other and therefore find out how measurements from O-funnel varies with different concrete mixtures.

Inledning: Att som förälder få ett barn som vid födseln är sjukt eller får en sjukdom strax efter födelsen är traumatiskt och medför stora påfrestningar för föräldrarna. Barnet behöver medicinsk vård och specifik omvårdnad vilket kan medföra att den så viktiga anknytningen mellan främst mor och barn blir fördröjd och försvårad.Syfte: Studiens syfte är att beskriva mödrars upplevelse av att knyta an till sitt barn, när barnet vårdas på en pediatrisk vårdavdelning under nyföddhetsperioden.Metod: Fenomenologisk ansats med kvalitativa intervjuer. Resultat: I studiens resultat framkommer tre huvudteman, att knyta an försvåras av separation, att knyta an genom amning samt att knyta an genom delaktighet. Separationen mellan mor och barn medför att mödrarna upplever att anknytningen försvåras. Utebliven information gör att mödrarna upplever ovisshet, rädsla och att inte ha kontroll.
