ABSTRACT System development has become more and more concentrated on development for the Web and this has resulted in larger target groups. It will most surely continue to be so considering that the Web will be the infrastructure of business and services in the future. A big target group involves that the owner of a system can earn a lot of money from the paying users, but that assumes that the system can meet user needs. If a system on the Web does not satisfy the user?s demands then they will use the competitor?s system instead because it is only a mouse-click away.

This Master degree project has been performed at the Braviken paper mill on papermachine 53 (PM53) which produces newsprint paper. The current economic situationhas contributed to declining demand for newsprint, which means it is extra important tobe competitive by high energy efficiency. Particularly as energy prices are expected torise when the economic growth returns.One way to increase energy efficiency is by reducing the water use in paper and pulpmills and consequently save energy through reduced heating of water. The thesis's maintask is to evaluate whether a water purification plant (microflotation plant) forpurification of process water in PM 53 is profitable. The microflotation plant enablesreuse of warm process water instead of losing the energy to receiving waters.

The aim of this studie is to describe, analyse and understand the benefits and disadvantages with using digital tools in education. In my qualitative method three primary school teachers were interviewed about how digital tools should be used in educational purposes, also what benefits/disadvantages they could see with the investment of digital tools in their school. I also did observations in two classrooms and interviewed a school politican to get a wider perspective. The collected information identifies that some benefits of using digital tools is the contribution to a more equivalent education, more opportunites for cooperations and that fewer pupils have to struggle with their fine motor skills when producing a text. Some of the disadvantages with using the tools is that they breaks sometimes, it´s easy to get dependent and if something happens (like power outage) it´s unusual that schools have a good an action plan.

Författare: Elin Sjöberg och Linda WibergHandledare: Anders IsakssonDatum: 2008-05-20Ämne: KandidatuppsatsE-post:  elin_sj@hotmail.comlindowiberg@hotmail.comSedan en tid tillbaka har fokus på företags ansvar gentemot miljö och samhälle ökat, detta har bland annat resulterat i att allt fler företag väljer att publicera hållbarhetsredovisningar. Hållbarhetsredovisningarna visar den ekonomiska utvecklingen som är bunden till sociala, etiska och miljörelaterade förhållanden. Samtidigt har saker börjat hända på finansmarknaden då både institutionella investerare och vanliga kunder ställer krav på att fondbolagen ska erbjuda produkter som har en etisk inriktning, så kallade social responsible investment, SRI. Informationen för att göra SRI-anpassade beslut och för att bedöma om ett företag får ingå i en etisk anpassad fond hämtas från flera källor, där hållbarhetsredovisningar är en av dem. Forskning visar på att det som redovisas i hållbarhetsredovisningar inte alltid är den information som en analytiker behöver för att på ett effektivt sätt kunna göra sin värdering av företaget.

Syftet med detta examensarbete är att göra en jämförande studie mellan faktorerna som enligt en teoretisk ram påverkar en miljöinvestering och faktorerna som ingår i ett företags bedömnings-modell. Respondentbolaget begärde i ett tidigt skede att få vara anonymt och benämns därför som Företaget. Det är en multinationell koncern med verksamhet i många skilda branscher, men med fokus på norden och produkter som kan kopplas till lantbruk. Den teoretiska referensramen har sin utgångspunkt i begreppen värde och investering samt hur deras koppling till miljö och miljöinvesteringar för att identifiera de faktorer som påverkar en miljöinvestering. Faktorerna som ingår i den teoretiska referensramen och som jämförs mot respondentbolagets faktorer är:? Investeringens värdetillförsel? Investeringens miljöpåverkan? Hur investeringen påverkar produktionsförutsättningarna? Krav från samhället? KundkravKopplingen däremellan bedöms enligt en femgradig skala.

Uppsatsens syfte är att undersöka två företag med olika ägarförhållande och vinstintresse, för att se om de skiljer sig åt avseende vad de prioriterar att kommunicera av sitt CSR-arbete till sina intressenter, samt vilka CSR-kategorier företagen väljer att arbeta med. Vår avsikt är att undersöka om och hur ägarförhållande och vinstintresse kan bidra till att forma företagens CSR-strategier. Området är intressant att undersöka då ägarförhållande och vinstintresse som bidragande faktorer till att forma CSR-arbete och kommunikationen av detta är relativt outforskat..

To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.

A couple of hundred years ago half of the earth?s surface was covered by forest. Today, only half remains and every year an area the size of Nepal is disappearing. Deforestation, together with the burning of fossil fuels, is also one of the reasons for the increasing greenhouse effect. Another relatively unknown problem for the world?s forests is the trade with illegally harvested timber.

Many reports infer that questions of HBT and homophobia are either poorly addressed or not addressed at all in schools today. This study is based on interviews with teachers of students aged 13 to 15. It is an inquiry to the teacher's thoughts about, knowledge of, and sense of responsibility to inform students of the subjects 'Queer', 'HBT', and 'Homophobia'. Who is responsible for educating the students regarding these subjects and what do teachers think about including these subjects in their curriculum? How do the teachers describe their knowledge of the subjects? Do they require further knowledge themselves in order to educate others in a proper way? The study is grounded in queer theories.

?A culture center should be visually welcoming as well as attract a diverse range of visitors with different backgrounds.? This was the client?s request for a new cultural center in Nairobi. The location is in the heart of Nairobi?s industrial area, near several existing buildings that are already in use by the culture organization known as Go Down. I have chosen to keep most of the existing buildings and to use my new building as a complement for the desired program.

The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted as a tool to assist the industries in their efforts to change the relationship between the consumption of energy and production. This by improving energy efficiency and a shift to the best available technology. During the past 30 years the steel industry has reduced its energy consumption per ton of steel produced by 50 percent.

In 2010 there will be a political resolution to ensure that the Swedish society is accessible to all citizens including people with disabilities. For this purpose a national action plan for disability policy "From patient to citizen" (Govt. Bill 1999/2000:79) has been set out with the aim of ensuring that the disability perspective will permeate every sector of society and that the approach and response to people with disabilities will be improved. The Swedish National Council for Cultural Affairs is responsible for implementing the disability policy in the cultural sector.Since public libraries in Sweden are a part of the public cultural sector, they will also be affected by the political resolution regarding accessibility. The concept underpinning library services for disabled people must be that of equality of access.

SAMMANDRAGLerums kommun har en vision om att bli Sveriges ledande miljökommun till år 2025 eller tidigare. En stor del av arbetet, som kännetecknas av hållbarhet, kreativitet och inflytande, sker i Gråbo. Det är idag en ort som känns bortglömd och är lätt att passera utan vetskap om dess placering. Samhället har såväl synliga baksidor som är i behov av förbättring och förnyelse, som outnyttjade tillgångar som bör lyftas fram.Syftet med föreliggande arbete är att ta fram förslag på hur Gråbo kan förbättras både med avseende på hållbar samhällsutveckling samt estetiska och funktionsmässiga förbättringar av samhället.Arbetet påbörjades med en faktainsamling, som sedan låg till grund för en inventering på plats i Gråbo. Detta sammanställdes till en analys där tillgångar och problem presenterades med hjälp av Adobe Illustrator till flera kartor.

This thesis aims at determining the heat losses in a property vent stack and its roof valve. Upon request of a company, the vent stack is analysed for possible heat recovering solutions to be implemented, while relining of the drain system is executed and with a suitable payback time for the economic investments. The heat loss calculations are based on data for properties that are located in the Stockholm region, but also easy to change depending on the situation. The calculations are done on pipes made out of cast iron, which still is the most common type of drain pipe in Sweden, and these are the pipes that relining is usually made on. The calculations that needed to take several variables into account have been done in MatlabR2014a and the thermos dynamical properties that were used in those calculations have been extracted from EES.Three different types of heat losses in the vent stack have been taken into consideration in this thesis.

In some coastal areas in Sweden water shortage sometimes appears because the withdrawal of groundwater is greater than the groundwater recharge. It creates a situation where the available groundwater is insufficient to support residents and businesses with drinking water. The high withdrawal of groundwater also creates a risk for saltwater intrusion to drinking water wells. The problem most commonly occurs during the summer when the groundwater recharge is low, but the population is high, due to tourism and summer residents.The purpose of this study was to investigate how local water supply in areas affected by water shortage can be solved as sustainable as possible. The work was divided into three parts where the first part comprised of a literature review on water systems in which four different options were investigated: artificial groundwater recharge, rainwater harvesting, desalination and water reuse.
