This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

Aim: The purpose of the study was to investigate how the assessment and grading is designed and practiced in the practical courses of physical education at GIH - the Swedish School of Sport and Health Sciences, along with how it could affect newly graduated physical education teachers? ability to assess and grade students. The study was based on Habermas?s system and life-world theory.What view occurs concerning proficiencies, basis for assessment and marking among teachers who are responsible for examinations within physical education at GIH?How is the examination structured within physical education at GIH?How are skills and proficiencies among assessment and marking further mediated to students in the teacher education at GIH?Method: The case study was realized by performing qualitative interviews with a total of four teachers at physical education at GIH. Additionally, syllabi were text-analyzed to improve the validity of the study.Results: From the results we found that the teachers experience marking as a complicated assignment, where particularly the didactic ability but also the practical ability form a formative and summative assessment.

Swedish school children's results have deteriorated in recent years and formative assessment is, in accordance with previous research, a way to develop students' learning and performance. A part of formative assessment is based on feedback that students should receive before, during and after a new assignment. In this study, we want to find out how students and teachers apprehend students' development in relation to feedback and what general attitudes towards feedback can be seen in both parties. The literature and theory discussed is linked to formative assessment, both at international and national level where many important aspects of formative assessment are essential in relation to pupils' further development. The theories are based heavily on human interaction and socio-cultural perspective as a concept.

Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available.

Pupil achievement and behaviour in schools was earlier seen as given by socioeconomic and biological factors. But since the late 1970s the school effectiveness research has come to give school factors a much greater role for pupils? attainments. Research has shown that schools´ pedagogical and social climate, which is to be seen as a complex product of deeply felt values and norms held by school principals and teachers and developed through practical actions, can explain variations in effectiveness between schools. Effectiveness is here to be seen as a higher mean cognitive and non cognitive student outcome than is expected with regard to initial attainment or family background.

With this study, our purpose has been to achieve profounded knowledge and understanding regarding the use of discretion among social workers specialized in social allowance issues. The Social Services Act, structured as a framework law in the Swedish context, provides the social worker with a certain degree of discretion, in order to enable accommodated decisions depending on client case specifics. This study problematizes these aspects of legal security, and our intention has been to examine which factors impact the assessments social workers carry out in statutory decisions of social allowance applications. To attain this, we narrowed down our intention into a number of distinct and delimitated research questions: (1) Which elements of the client case impact the social worker?s assessment? (2) Which external aspects influence the social worker?s assessments and decisions? (3) How do social workers decide the client?s credibility? In order to establish answers to our research questions, we have utilized a qualitative approach of research by exerting qualitative interviews in addition to a vignette study.

During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.

My aim is to find out about teachers? perceptions of methods concerning learning and assessment of oral proficiencies. My questions are: What perceptions are there among teachers concerning assessment of oral proficiencies? How do teachers describe their ways of promoting and assessing oral proficiency? In order to answer my questions and obtain data I have accomplished two focus groups interviews with seven language teachers. The result shows that teachers are concerned with several factors regarding assessment of oral proficiency.

AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.

The lack of fresh and clean water today causes severe problems, mostly in developing countries. Waterborne diseases like typhoid, cholera, amoebic dysentery and diarrhea create health problems and deaths among people. There is a need for low cost interventions like household-based water treatment and safe storage (HWTS). Solvatten AB is a Swedish company based in Stockholm. Their product, Solvatten, is a household water treatment unit that can treat water containing viruses, parasites and bacteria.

The aim of the study was to examine how social workers investigate and assess addiction cases whether gender matters or not. The following questions were asked in the study; ? Does the gender of the client influence whether a case is opened after the first meeting at the Addiction Unit? ? Do social workers consider there is a difference in handling an addiction treatment investigation when the client is a man or a woman? ? Do divergences exist in the assessment and the final decision process when the case concerns a man or a woman? The study is based on the qualitative method. The material is gathered from semi-structured interviews with social workers. Their job tasks include assessment and evaluation of addiction cases.

The students participating in my development work will work with a process book for handicraft studies. In the beginning of their studies, the students need practical knowledge about the development of the profession itself, but they also need to be challenged and learn how to solve problems on their own which will help them gain a deeper knowledge of the subject.    I focus on open questions to create a process with the students. This process is created when working with Solution-Focused-Education. Through ?assessment for learning? we can help the students to improve their self-assessment and understanding of the learning process.

Today's climate and environmental issues have now been up for discussion for quite long. Various environmental measures have been taken, but it is not always certain that those measures actually are for the better because of the complexity of our environment. Therefore, studies of whole life cycles are very important even if they are time and resource intensive.Real estate accounts for 15% of global carbon emissions, but also affects our environment in many other aspects. In Sweden this number is even higher. About 30 % of its carbon dioxide emissions originates from building sector and changes are therefore of great importance.
