Relationship between moose (Alces alces) home range size and crossing wildlife fences
Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.
Kvinnors upplevelser vid missfall och deras efterfrågade stödinsatser : En litteraturstudie
Background: Miscarriage is a common phenomenon in our society. It is reported that approximately 17 % of all pregnant women in Sweden go through a miscarriage every year. For many women miscarriage is a tumultuous life event that often has a deep emotional impact. Miscarriage is a subject that often is prohibited to talk about in our western society. Consequently this means that nurses have an important role in the emotional support for these women.
KOGNITIV PROBLEMLÖSNING UNDER STRESS : PÅVERKAR FYSIOLOGISK AROUSAL PRESTATIONEN?
Förmågan att prestera under akut eller kraftig stress är en förutsättning för en del yrken. Forskningsresultaten gällande hur stress påverkar prestation pekar åt olika håll. Denna studie undersökte sambandet mellan fysiologisk arousal och kognitiv problemlösningsförmåga under stress. Trettiotvå polisstudenter testades på Ravens test av flytande intelligens APM set II både före och efter att antingen ha sprungit i tjugo minuter eller haft en självskyddslektion på ca fyrtio minuter. Resultaten från en mixed ANOVA för beroende mätningar visade på en signifikant interaktionseffekt (F (30) = 6,547, p < 0,05) ? en ökning i prestationen hos självskyddsgruppen med arton procent och en minskning med femton procent hos löpningsgruppen.
Studenters upplevelser av handledning : under specialistsjuksköterskeutbildningen med inriktning anestesisjukvård
The aim of this study was to learn how students in specialist nurse education with direction towards nurse anaesthetist experienced tutorial given during their specialist placement. The chosen method of the study was qualitative interview with phenomenological approach. Twelve nurse anaesthetist students were interviewed about their experiences during their placement at operation wards. The interviews were transcribed and analyzed according to Giorgios (1985) analyze method. The result showed that the students considered that a well functioned tutorial was essential for a successful clinic placement. The tutorial considered as satisfactory if the student and the tutor managed to have good communication and a good relation with each other.
Bakteriell produktion i humösa istäckta sjöar i norra Sverige
The main purposes of this study were to 1) quantify bacterial production in winter during ice conditions, and 2) to compare these production measures with values measured from summer and open water conditions in three humic lakes situated in northern Sweden. Another purpose of this study was to 3) examine whether clear-cutting significantly affected bacterial production or water chemistry in two lakes situated in catchments were a large part of the forest had been removed through logging compared to an undisturbed reference lake. In winter (March/April 2014), the bacterial production ranged from 0, 7 - 2, 2 µgC/L/day and in the summer of 2013 the production values was 4 ? 10 times higher. The main reason for lower bacterial production in winter was ascribed to lower water temperatures as well as to older and more recalcitrant DOC, as there were no significant differences in total dissolved nitrogen or DOC concentration or -quality, that could explain a lower production compared to summer.
Källor i Lagga, en uppländsk slättbygd : Geografisk och geologisk påverkan påkällvattens egenskaper
For centuries, springs have played a significant role in our society as water supplies, reasons for where to settle down, and in folklore. There are different reasons why and where a spring forms, e.g. in what kind of soil it has its outflow. Geographic and geochemical surroundings have an influence on spring-water quality.For this project some of the springs in the Lagga perish, Knivsta municipality, Sweden, were selected for a closer study. Water samples were collected from springs for analysis.
Modellering och optimering av Lycksele kraftvärmeverk
Stigande kostnader för bränsle samt pressade elpriser gör att produktionen för ett kraftvärmeverk bundet till ett fjärrvärmenät måste optimeras. I denna rapport presenteras en ?Mixed integer linear programming? modell över Skogsbacka kraftvärmeverk, dess ackumulatortank, extrapannor och Lyckseles fjärrvärmenät tänkt att kortsiktigt optimera energiproduktionen. Kraftvärmeverket har en panneffekt på 50 MW och turbineffekt på 16 MW. Modellen tar hänsyn till fjärrvärmenätets framledningstemperatur och returtemperatur samt hur dessa parametrar påverkar kraftvärmeverkets drift samt hur de påverkar ackumulatortankens lager och laddning.
Stubbskörd : från modell till verklighet
In the near future we need to reduce the greenhouse gas emissions significantly for the benefit of the environment around us. The European Union has de-manded a variety of climate and energy goals to be achieved by year 2020, the ?20-20-20? targets. With these aims, The European Union means that we must reduce our emissions from fossil fuels and instead increase our renewable fuels.
With stump harvest in the forest it?s possible to increase the use of renewable fuels and reduce our emissions from fossil fuels.
Nivågruppering i Engelska : En fallstudie på en gymnasieskola i en Stockholmsförort
The purpose of this degree thesis is to investigate what the English teachers in an upper sec-ondary school, think about teaching students in ability grouped classrooms. The questions that I have set out to investigate include what the teachers think about ability grouping in English, the school?s current organisation of ability groups, the pros and cons of ability grouping in English, differentiation in teaching and if students get more individualized teaching with abil-ity groups, how the teachers cooperate and what would be the optimal teaching situation in an English learning classroom.I did a lot of theoretical research on the subject and studied old essays on similar subjects. I also did some classroom observations to use as background information for my interviews. I interviewed five teachers of different sex, age, and teaching experience.
Lokalisering av sågverk i Västerbotten : en jämförelse mellan två alternativ
The number of sawmills in Sweden has decreased dramatically since the 1980s and the trend looks set to continue. The sawmills that are left instead becomes larger and are situated farther apart. In northern Sweden, they are concentrated along the coastline.In our study, we compared conditions for running a sawmill in inland areas and coastal areas and looked at what factors have the greatest impact on the profitability of the sawmill in northern Sweden.We chose to compare different locals conditions for a sawmill that only sawn pine timber and had an annual raw material requirements of 300 000 m3ub per year. By analyzing the kNN-data from the Swedish National Forest Inventory we have taken out the size of the timber volume at each site and its catchment. We have also looked at possible competitors in the areas that may affect the purchase price of the commodity.

Värmeslag hos hund : Förebyggande åtgärder, djurägarråd och omvårdnad
The objective of the essay was to identify the nursing care required by a dog suffering from heat stroke and how to educate and advice the owners how to start treating their dog and prevent the condition from occurring in the first place.
The essay is based on a literature study. Several databases were searched for scientific research to try find answers to the issues. Keywords concerning the subject were used and mixed in different combinations to sort out the suitable studies.
The results of the study indicate that the dog should be cooled by the owner directly after detection. The most crucial issue is to reduce the body temperature as quickly as possible or the morbidity will worsen.
Hybridlärkens tillväxt i Snogeholm : hur påverkas produktionen i blandbestånd jämfört med trädslagsrena bestånd?
The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests.
The purpose of this thesis was to document the production of hybrid larch planted in the Snogeholm landscape laboratory and to compare the production in the pure hybrid larch stand with the mixture together with pedunculate oak (Quercus robur).
The data collection in Snogeholm since the establishment has been carried out by the Swedish University of Agricultural Science (SLU). The fieldwork for the thesis was carried out in 3 stands, containing hybrid larch, pedunculate oak and a mixture of hybrid larch and pedunculate oak, in order to be able to compare the total stand production of the areas.
The results show that the total production of hybrid larch in the mixed stand only is 35 % compared with the total production of hybrid larch in the pure stand. Therefore, the hypothesis that the total production of hybrid larch is equal to the planted mixture with pedunculate oak was rejected.
The other hypothesis that the total production of a 2 hectare large stand containing a mixture of hybrid larch and pedunculate oak would be greater than the total production of two pure stands of 1 hectare containing hybrid larch and oak each was also rejected. In the studied case the total production was 45 % greater if hybrid larch and pedunculate oak was planted in pure stands.
The results from the case-study only indicate that the total production of hybrid larch and oak under the investigated conditions can be higher when planting the two species in pure stands compared with a mixture of the two species.
