The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF). The literature study covers earlier work that has been doneregarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.

This bachelor thesis discus how store managers at Clas Ohlson motivate their co-workers at their everyday work.Motivation at work is essential, since engaging co-works makes the everyday routine work more effective. Otherwise that type of work can easily lead to unhappiness at the workplace which leads to less motivated workers, poor performance, even less motivated workers and this will start a negative circle.Other studies has shown that to in order to be pleased at a workplace and to keep qualified co-workers, the leaders needs to have knowledge in how they can use different techniques to increase staff motivation, but still motivation is not considered being an economic means of control. This has made me think about how leaders can motivate their workers at their everyday work.The questions at issue are:o How can leaders motivate co-workers in everyday work,o Which preferences the leaders consider control the individual motivation ando Which methods they can use to increase the motivation in the routine work.The purpose with this thesis is to study how leaders use their leadership to motivate workers to perform everyday work with more enthusiasm. To answer the question I have interviewed store managers at Clas Ohlson.In this thesis I have used a qualitative method, and I have compared relevant theories with the interviews I have done. Thus primary data has been gained through one-to-one interviews but also through mail interviews.

The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.

Introduktion: Läpp-käk-gomspalt (LKG) är en av de vanligaste medfödda defekterna. Det beräknas att det i Sverige föds cirka 200 barn per år med olika typer av läpp-käk-gomspalt, drygt 2/1000 födslar varje år. Defekten medför ett stort behandlingsbehov, vanligtvis utfört av ett specialiserat LKG-team. Teamet består av flera specialister inom olika områden, till exempel plastik- och käkkirurger, ortodontister, logopeder med flera då defekten bland annat medför påverkan av ansiktets utseende, talsvårigheter samt bett- och tandavvikelser. Läpp-käk-gomspalt kan påverka livskvaliteten hos barn och ungdomar och behandling och hjälp från olika vårdgivare kan hjälpa till att höja livskvaliteten.

Dynamisk motorisk talbedömning (DYMTA) är ett nyutvecklat test för diagnosticering av verbal dyspraxi. Verbal dyspraxi är termen för barn som har en nedsättning i förmågan att viljemässigt programmera motoriken vid talproduktion. Den här studien syftar till att stärka den kliniska användningen av DYMTA genom att bidra till insamlingen av referensdata från typiskt utvecklade barn. Studien tillhör ett större doktorandprojekt där sammanlagt tre magisteruppsatser kommer att bidra till insamlingen av referensdata av barn med typisk tal- och språkutveckling. I föreliggande studie undersöktes 16 barn i åldern 4:0?4:11 och 17 barn i åldern 7:0?8:11 med DYMTA och ett omfattande testbatteri.

In June 2006 the Swedish government decided that the use of energy in buildings should be reduced by 20 percent until 2020, compared to the level of energy used in 1995. To contribute to this goal, the real estate company ?Eskilstuna Kommunfastigheter AB?, set up own goals for their buildings. In 2009, the goal for schools was to have a maximum energy use of 118 kWh/m2year for heating and hot water.The school ?Hållsta skola?, just south of Eskilstuna, exceeds the limit since it used 270 kWh in 2008.

Background and problems: All that is stated in social media might not always sometimes be right, which has consequences for the individual's view of the described phenomena. The individual interprets and takes in mass media messages, which can lead to that the wrong information makes believed to be is correct one. The news media?s photo illustrations might pictures result in bad images of the suburbs. Hovsjö, residential area in the city of Södertälje, occurs in the media depicted as is a bad place to live due to the high rate of crime there.Purpose and Issues: My main research question is: How do young people view their residential area Hovsjö in comparison with the image they believe consider is given in that the news media gives the area? Further questions of the study are: How do the young people of the district describe their residential area? How do the youth's react to the news media images of Hovsjö? Has the neighborhood helped to form their identity?Method: In my data collection I have chosen a qualitative approach with observation and semistructured interviews.

This thesis concerns how Sweden relates to life cycle assessment (LCA) in the construction process. LCA means analyzing a products impact and the analysis includes the whole life span of the product. A building has a high complexity and the combination with its unique shape will make the LCA more comprehensive, unlike e.g. aluminum cans. Recently there has been a development of a working procedure in the construction industry.

During 2008 we experienced an expansion of large scale investments in foreign farmland. This increasing trend has become a political hot-spot, but there is not much research available within the field. Due to a lack of research it remains a vital task to outline the potential effects of this trend. Drawing on existing ideas from some of the main actors within the field, The Food and Agriculture Organization of the United Nations (FAO), The World Bank, International Food Policy Research Institute (IFPRI) and the latest G8 summit on agriculture, four main purposes are set out for this paper. First, to outline some of the underlying mechanisms behind the trend is considered crucial for the understanding of the nature of these investments.

Den vanligast förekommande sjukdomen hos unga kalvar med infektiös orsak i Sverige är diarré. Enterit kan leda till uttorkning, acidos, rubbningar i elektrolytbalansen och i värsta fall dödsfall. Snabbt insatt behandling är avgörande. Till kalvar med fungerande digestionssystem rekommenderas i första hand behandling med oral vätsketerapi. Endast lite forskning har utförts om hur kalvar helst dricker sitt vatten.

Background: Today, the tourism sector is one of the economically fastest growing sectors in the world. Volunteer travel is a type of service that is gaining in popularity and a number of tour operators organize these trips. Few aid agencies engaged in volunteer activities and therefore the interest in volunteer travel is caught by tour operators. These tourists travel in small groups and interact with locals. Today fifty million children in Africa are orphaned and Africans struggling with the care of these children by founding orphanages.Research questions:What does volunteers contribute with during their stay at orpahanges?What view does volunteers and orphanages have on volunteer tourism?Purpose: The purpose of this paper is to examine the positive and the negative effects that volunteer tourism contributes to orphanages.Method: The study is based on a qualitative approach with semi-and unstructured interviews, observations, and email interviews.

It is found that the properties of the record years of 1965-1975 is leaking a lot of energy andthese properties are facing a major energy efficiency. From the energy aspect, the facade isafflicted with poor thermal insulation which is a big problem. To address this problem addinginsulation is a good alternative to reduce overall energy consumption of a building. Thewindows on these buildings are also a problem from the energy point of view. Therefore,there are many reasons considered for energy upgrading.

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.
