Friidrottsungdomars fysiska kapacitet över tid : En retrospektiv studie av intagningstesterna vid friidrottsgymnasiet i Växjö mellan åren 1982 ? 2009
Background: Today when leisure time is spent, spontaneous sports activities decrease, due to a more comfortable way of living and physical capacity among non active adolescents decreases. There for it´s interesting to see how the physical capacity level has changed over time among young people participating in organized leisure time sports.Studies around the world show that young people standing outside organized sport activities have tended to decrease their physical activity levels over the last few decades. Less leisure time is spent doing physical activity and sometimes gets put into context with increased time spent behind the computer or inactivity.Design: A retrospective study of the test results on physical capacity between 1982 and 2009 for students applying to Växjö track and field high school. A total of 635 students (15 years old) have done 11 physical tests during the years. Five of these tests, with enough participants (at least 100) and documentation over at least 10 years, were used in this study.Results: This study shows that young track and field athletes have maintained the same physical capacity from 1982 to 2009.
Vidhäftning mellan prefabelement och pågjutningsbetong : Undersökning hur skrovligheten påverkar vidhäftningskapaciteten vid skjuvning
Self-compacting concrete has soon been around for a decade. Recently the prefabrication industry has started to use this fairly new concrete type in larger scales, mainly because of its distinctive properties. There are still certain areas that need to be thoroughly examined, such as bond capacity. There have been very few studies regarding shear capacity due to the fact that the procedure is complicated.This report will highlight a method to examine the shear capacity of different surfaces that have been prewetted as well as non-prewetted surfaces. The surface areas follow BBK 04?s and Eurocode 2?s demand for surface roughness. A smooth surface will be completed in order to confirm if the different shapes influence the bond strength by shear stress or not. The purpose of this essay is to measure the bond strength within the shear capacity as well as examine the impact it has on surface roughness and treatment for shear bond.The method used to identify the shear capacity is called L-shaped Push-Off Test.
Arbetsminneskapacitet: relation till verbalt flöde och indirekt minne för inhiberat material
Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.
Jämförelsestudie för tre olika metoder att beräkna genomstansning i betong : Skillnader i genomstansningskapacitet för metoderna i BBK04, EK2 och BHB
Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.
Utvärdering av anaerob behandling av hushållsspillvatten och tekniker för efterbehandling
The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.
Planseparerad spårtrafik i Göteborg
The City of Gothenburg has an urgent need to upgrade its public transport. The capacity of its light rail transit (LRT) has reached maximum capacity within the inner city limits years ago. The construction of an underground metro will be very expensive and time consuming due to the soft clay beneath the city. The apparent need of developing another type of mass rapid transit (MRT) is urgent. An elevated metro have turned out to be a success in Greater Vancouver, but is it possible for the system to operate well in Gothenburg with its narrow streets and current land use; will its route coexist with the current LRT or will the noise disturb people too much?.

?-galaktosidas assay för studie av promotorregion i kloritdismutas från Ideonella dechloratans
Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.
Känsla av sammanhang på Samhall : Arbetare med nedsatt arbetsförmåga
Sense of coherence amongst employees with reduced work-capacity at Samhall.Sanela Jakupovic TrostekScientific essay in public health, 15 hp, Academy of Health and promoting Working Life, University of GävleThe aim of this study was to examine how employees at Samhall who has reduced work-capacity experienced their sense of coherence (SOC). The study includes gender, age and civil status in the analysis. The study includes 34 respondents which are divided as 20 men and 14 women. To measure SOC a quantitative method with a 29 standardized questionnaire was used.It was found that the employees felt, in general, low SOC, which means more difficult adaptation to their life situation. Noteworthy is that 70 % of the men in this study showed low SOC compared to 35,7 % of the women.One conclusion that can be drawn is that within Samhall, it showed that women had a higher SOC mean value than men which means they are more equipped to handle, understand and find meaning in their work life. Keywords: Antonovsky, Samhall, disability, work-capacity, sense of coherence (SOC).
Geotermi i Ungern : Undersökning av Ungerns energisituation inriktat på geotermi samt kapacitetsfaktorn för det största geotermiska värmeverket i Mellaneuropa.
Hungary?s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy.

Att lära av varandra? : En undersökning om arbetslag utifrån ett lärarperspektiv
The purpose of this study is from a teacher?s perspective to examine how schoolteachers experience the possibilities of learning from each other within their work team and to shed some light on how teachers believe that cooperation affects their ability to learn and improve on a daily basis. My research questions are: What is the general discussion among the teachers concerning daily capacity building from enhanced teamwork? How important is well-functioning cooperation between co-workers for learning and daily capacity building? What are the prerequisites for a well-functioning learning situation within the work team?The study is based on five qualitative interviews with teachers within the same school but from different teaching backgrounds based on what grade they teach, what subjects they teach, and they belong to different work teams within the school. The interviews are semi-structured.The results have been analysed from a perspective based on the theories of organisational pedagogy and learning organisations.The results implies that the work teams does not function as a forum for exchanging experiences and learning from each other.
Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]
Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. Thus, the wastewater will be more concentrated and will originate from the households only. The Sjöstad project includes the idea of a local treatment plant for the household wastewater. To evaluate this possibility, Sjöstadsverket, an experimental treatment plant was constructed.
Bättre åtkomst till avverkningstrakter med anpassat marktryck från avverkningsmaskinerna
The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.
