Standardisering av snöröjningsplan : Instruktioner, råd och tips för snöröjning av tak med stora spännvidder

The Swedish winters 2009/10 and 2010/11 were rich in snow and many roofs collapsed, mainly largespan frames. Investigations were made and the amount of snow was not the primary cause, insteadthere were several other causes. One of these was that in some cases roofs were shoveled in anunfavorable manner which affected the load patterns negatively, so causing the roofs to collapse.Most people lack the knowledge of how shoveling will affect the roof. Had there been an increasedunderstanding regarding shoveling, some roofs could have been prevented from collapsing.Through both qualitative and quantitative research in the form of interviews and calculations thetheoretically best ways to shovel a selection of roof types is presented in the report. The roofstructures covered are 3-compartment, continuous and Gerberspliced metal roof decks.

Skadeanalys och omkonstruktion av HMS Belos A-ram

In order to rescue a distressed submarine crew, the Swedish Navy is able to use a deep submergence rescue vehicle, DSRV. This mini submarine ascends, docks to the downed submarine and picks up the whole crew. The submarine rescue ship HMS Belos has a special crane located in the aft of the ship to lift the surfaced DSRV aboard, which then docks on to the on board pressure chambers located below deck. During inspections the aforementioned crane has shown to have problems with cracks in the structure, most of them located in the bolted joint between the top part of the crane and the two leg parts. A simulation of the forces acting on the structure in heavy sea condition was conducted; these values were then used as input values in a Finite Element Method, FEM, analysis of the joint.

Tre parker i Höganäs : bevara och förnya

The purpose of this master dissertation is to show an example of how to renovate three different parks in an area of national interest in Höganäs, Sweden aiming to deal with their heritage value as well as making them attractive to today?s user. The question formulation can be described as following: How can i as a landscape architect renovate parks with different characters conserving their existing qualities. By studying and documenting the park´s history and current usage and using methods of evaluating a park?s heritage value ( Kulturhistorisk värdering av bebyggelse, Unnerbäck 2002) i could conclude which qualities to conserve and suggest and motivate what features to add or renovate.

Samband mellan lågt tryck i dricksvattenledningar och magbesvär - En utredning av hur lågt tryck på dricksvattenledningsnätet vid lagning av läckor påverkar sjukligheten hos Göteborg Vattens abonnenter.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Utvärdering av VAV i nybyggt kontorshus

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Tankar om ett kök

The kitchen is one of the most important rooms in our homes. It is a place for social engagements, meetings between people and activity. How the kitchen looks today is a concept sprung from the Swedish kitchen standard of 1952. Eventhou this standard no longer exists it is a model of how kitchens are designed today. The kitchens most often sold today come from one of four major kitchen manufacturers in Sweden.My thesis investiges an alternative kitchen concept.

Människovana grävlingar som testdjur för grythundar. En studie om hur grävlingars beteende och fysiologi påverkas av hundars aggressivitet

In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).

Utmattning av vägbroar i armerad betong enligt eurokoder

Since 1 January 2010 it is a requirement to use the European standards, Eurocodes, in Sweden when constructing bridges. One chapter that has caused an extra amount of problems for the engineers is the one about fatigue analysis, which resulted in us doing this thesis.To do this we had to read all of the Eurocodes that direct, or indirect deals with fatigue and calculating of such. We have read the background documents for the Eurocodes and master?s thesis in the subject. We also studied the calculations of bridges constructed by different construction firms.We have chosen to limit the thesis to discuss only road bridges made of concrete due to the lack of method for verification of concrete in the national appendix.

Upplevelser i samband med en obotlig cancersjukdom : En litteraturstudie baserad på vetenskapliga artiklar samt självbiografier

BACKGROUND: One of the nurse?s areas of responsibility is to relieve suffering. Research has shown that nurses give an indication of an emotional load in the interaction with dying patients. This means that patients need of relieved suffering gets disregarded because of nurse?s fear of the unknown.

?Du kan göra skillnad i människors liv utan att ha en aning om det? : En kvalitativ studie om några socialsekreterares syn på suicidalitet

During 2010, 1446 people committed suicide in Sweden. Research shows that groups that are less favored in society have an increased risk of suicide. Social services often encounter groups of people that have a high risk of suicide, for instance welfare recipients or substance abusers. The purpose of this study was to shed light on how social workers talk about suicide and how this might affect interactions with suicidal clients. The study is based on qualitative interviews with five social workers in Stockholm.

FE safety analysis of a high speed wood planer cutter. An alternative method to achieve the requirements of EN847 standard

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

Motiv och attityd till kompetensutveckling på två små företag

The aim of this study was to gain insight into how two enterprises work with competence development and thereby study how the relationship between competence development and workers, employees, look like. The focus was on the workers motives and motivation towards a participation in a competence development course, their attitude to education, and how the transfer of skills gained from the course, into the workplace looks like. Further on, the work situations influence on the workers competence development has been taken into account.In the study, six people were interviewed in the role of either manager, coach or course participant who are employed in two different enterprises in the south of Sweden.The results showed that the participants were motivated by a strive for personal development or that the participants viewed education implementation as a part of the professionalcareer, which has resulted in a positive attitude towards the competence development course. The managers? motive for decisions about education was to change the prevailing attitude among the staff for the better and thereby strengthen the company?s brand. The work situation has encouraged the desire to participate in developmental education as the feeling of control has encouraged the workers to further development.
