Utveckling av gran, Douglasgran, bok och tall under skärm av hybridlärk :

?Development of Norway spruce, Douglas fir beech and Scots pine with a larch Shelter wood? is a report written by Per-Olof Magnusson. The thesis is a compulsory part of forest engineer program at ?Skogsmästarskolan?, SLU, Skinnskatteberg, Sweden. The purpose of this report is to describe and evaluate an experiment with hybrid larch (Larix x eurolepis) as Shelter wood, and different tree species growth and survival depending on the density of the Shelter wood. The experiment is conducted by southern Swedish forest research centre, faculty of forestry, SLU in Alnarp. The hybrid larch ought to be an interesting alternative to birch (Betula sp.) as shelterwood on suitable sites in southern Sweden.

Tillväxtreaktion hos skärmträd i högskärm av gran i Medelpad :

Different methods for shelterwood cutting have been used in differ-ent parts of Europe since the middle ages. The use of Shelter wood cutting in Norway spruce (Picea abies (L.) Karst.) forests in Sweden met a revival in the early 1990s as an alternative for the dominating clear-cutting system when silvicultural costs increased dramatically for the latter. Shelterwood cutting systems involve some possible problems but also a lot of positive effects. Among the problems are increased risk of wind throw and damage of the remaining shelter trees caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity. This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden (62,4º N).

Kropp och själ bakom stängda dörrar : En kvalitativ studie om fysisk aktivitet hos kvinnor i skyddat boende

AimsThe aim of this study was to conclude whether women living and staff working in a women´s shelter feel experience a need of physical activity in the shelter and also what thoughts women living and staff working in the shelter have regarding possible access to physical activity. Following questions were adressed: Does women living and staff working in the shelter experience that there is a need of physical activity in the shelter? What does women living, and staff working, in the shelter think about the physical activity conducted in the shelter? Why does the women living in the shelter choose to participate in the physical activity? Are there any connections between symptoms which battered women can suffer from and symptoms which scientific studies say can be reduced by physical activity?MethodsThe study is based on five interviews in order to understand and illustrate how women living in a shelter relate to physical activity. The answers from the interviews has been correlated to scientific results and other literature in the area. Literature studies have also derived background information as well as a deeper knowledge regarding in what way violence against women affect the abused woman.ResultsThe results show a need for physical activity at the women?s shelter where this study was conducted.

Man har ju i alla fall tak över huvudet : En kvalitativ studie om natthärbärgets effekter på hemlösas självupplevda psykosociala hälsa

This is a qualitative study, whose purpose is to examine if night shelters effects homeless peoples self-perceived psychosocial health. In Sweden alone there are almost 18000 homeless people, and 12% of them uses a night shelter. The homeless can?t be seen as a heterogeneous group but instead homelessness counts as a state of being in. The Swedish National Board of Health and Welfare have done mapping over the homelessness since 1993 and the problem is an important part of what the welfare system has to fight against.

The violence against women is an important matter. In Sweden there are several organisations that takes care of the women and children in need.One of the many organizations you can turn to is women's shelter organizations. They are nonprofit organizations. They depend on the contribution of peoples free time and on the government's awareness of the work that the organization do. The social services has the main responsibility to take care of women and children in need.

Katterna på Kattstallet i Åkeshov : vilka katter är det som insjuknar?

The aim of this study was to see if there is any group of cats that are at greater risk to get sick and/or be euthanized during their stay at a cat shelter with no-kill policy.

Shelter use of horses during Swedish summer in relation to weather conditions and insect abundance

Outdoor housing of horses? best fulfils the horses? need for physical activity and it is an alternative to the more cost and energy demanding indoor housing in stables. Furthermore, if outdoor housed horses have access to shelter they can generally cope well with adverse weather conditions such as high or low ambient temperature, heavy rain or strong winds. In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to evaluate whether shelter use is related to weather variables (e.g., ambient temperature and wind speed) and insect harassment. The shelter-seeking behaviour was studied for three different groups of horses: Group 1) eight individually housed horses in paddocks that had access to three different shelter types (C: closed on three sides with roof, R: open on three sides with roof, W: closed on three sides without roof), Group 2) 25 group housed mares with foals on pasture with access to shelters C, and Group 3) ten mares without foals on pasture without access to shelter. Each group was studied for eight days.

SEMI : Ett projekt med syfte att presentera en ny lösning till katastrofbostäder

AbstractThe number of natural disasters are increasing. Disaster relief today is improving, but not enough.The purpose of my graduation paper is to present a new solution to shelters. It?s important to remember the human, social and environmental aspects when designing a shelter for disaster relief. Each group within the population has to be able to use the shelter and benefit from it.

Solceller som energikälla och solskydd för tält

This degree project is an investigation of solar cells and their ability to deliver electric power as well as reducing the need for cooling. The main object of interest is a BASE-X shelter. The shelter is purchased by the Swedish Defence Materiel Administration, FMV to be used for command and camp in the new force called Nordic Battlegroup, NBG. The demand on the equipment is firstly that it should have a small weight to be easy to transport and handle and secondly to be easy to bring up fast. Therefore the choice of solar cell technology fell on thin film cells.

Val av liggplats och väderskydd hos dikor vid utedrift vintertid

If you keep cattle in a herd outside all year round on big varying grounds, their possibilityto perform their natural behaviour increases. This way of keeping cattle requires that youprovide them with their other needs, like shelter and a dry and clean resting place.According to the animal welfare authority´s regulations on livestock farming, only animalsthat are suited to stay outside during the cold season are allowed to be kept outside. Theyshould also have access to a shelter or another building that gives them protection from theweather and wind and provides a dry and clean resting place.Research has shown that as long as cattle do not get exposed to precipitation and wind theywill manage low temperature well. Some of the things that will affect how well the animalshandle different climates are the isolation ability of the fur, the animals´ body size and thefeed intake. A dry lying place that is both insulating and moisture absorbent is also of greatimportance.

"Våld som våld... skulle jag tro": Kvinnojourers förhållningssätt till våld i samkönade relationer mellan kvinnor

The purpose of this thesis was to examine women's shelter representatives' views on domestic violence in same-sex relationships between women. The questions we posed were how women's shelter representatives relate to same-sex domestic violence, both from a theoretical and practical perspective, as well as if they are, or feel they should be, inclusive of women who are victims of same-sex domestic violence.We conducted a qualitative study, in which we interviewed eight women's shelter representatives. We then compared and linked our findings with previous research, including studies on the occurrence of same-sex violence, and ideas of similarity and differences between men's violence against women and same-sex domestic violence. We also linked our findings to theories on heteronormativity and structural theories surrounding same-sex domestic violence.We found that the competence and knowledge of women's shelter representatives varies greatly from individual to individual. Heteronormativity permeates the organisations to a great extent, from exclusive marketing and initial reception to a lack of interest regarding these issues.

Effekt på värdeutfallet av sågad vara vid övergång från 30 till 60 cm moduler : - en fallstudie av Moelven

The purpose of this study is to explain how the value of sawn wood changes when sawn wood are cut in 30 respective 60 cm lengths. The raw material into the saw mill will mainly be bucked in 30cm and 60 cm modules. There will also be two alternatives where the timber will be bucked special lengths, 370, 490 and 550 cm but also in 490 and 550 cm.The method used for the study is to simulate both cutting and sawing the woods. For cutting the simulator Timan is used and for sawing the simulator Timberopt is used. When data is generatedfrom the simulators, calculations of some key figures is done and also how much the revenue need to be increased for the sawn wood in order to cover for the increased costs of changing sawn woodfrom 30 cm to 60 cm modulesThe conclusion is that the single biggest reason, impacting the value of the sawn wood is the cutting at the saw mill.When going from 30 to 60 cm modules, the impact will be that the customers to the saw mill must pay more to increase the revenue by at least 10% for the sawn wood in order to justifice the changein production.It is also possible to increase the value of the products further by bucking the timber in three lengths, 370, 490 and 550 cm, in order to get 12 % increase of the share of longer sawn wood (>= 480 cm)..

Skogsbrandens påverkan på död ved :

Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris). Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.

Trä som fasadmaterial ? behandling och beständighet

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

Förekomst av agens i kattsnuvekomplexet på ett svenskt katthem

Conjunctival swabs from 12 cats in a Swedish animal shelter were analyzed by real-time PCR for FHV-1, Mycoplasma felis and chlamydiae. The purpose of this study was to see whether and to what extent these agents can be detected and if they were detected from cats housed in quarantine or in the adoption department. Samples were first taken upon arrival at the quarantine and then a second sample was taken two weeks after moving to the adoption department, or upon presentation of signs of disease. The cats spent the quarantine period in two separate quarantines: five in a new quarantine (quarantine A) and seven in a room in the old shelter (quarantine B). The difference between these quarantines was that in B the cats were often mixed together ant the hygiene routines were not as good as in quarantine A.
