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.
Traditionell ekologisk kunskap i en framtid med lokala, självförsörjande och urbana samhällen
Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..
100 tigrar i djungeln : En studie om Posttraumatisk stressyndrom hos barn
Abstract This essay will present actual research around the concept of Post- Traumatic Stress Disorder, how it can reveal itself in school children and how it can influence young people?s learning ability and capacity to retain knowledge.The purpose is, above all, to clearly diagnose PTSD so that children with this complex of problems can receive good possibilities in learning and understanding.The question at hand is responded to by interviewees with an expertise on the subject and one ?story?, collectively with literary studies.The results illustrate that there can be neurological and biological, as well as social explanations for PTSD but it is seldom a permanent diagnosis. It is though something to take very seriously. PTSD can lead to severe psychobiological consequences, mostly by causing damage in one particular part of the brain, known as hippocampus. The hippocampus is essential in terms of memory and concentration.

Jakten på vårdplatser som inte finns : En kvalitativ intervjustudie
Bakgrund: Vårdplatserna på svenska sjukhus har minskat drastiskt det senaste decenniet. Detta har inneburit en högre beläggning på de kvarvarande och medfört längre väntetid på landets akutmottagningar. Platsbristen skapar, ibland dagliga, överbeläggningar och utlokaliseringar av patienter.Syfte: Att undersöka hur sjuksköterskor och läkare upplever att vårdplatssituationen påverkar deras arbete och vad detta får för konsekvenser för patienterna.Metod: Kvalitativ design med semistrukturerade intervjuer med tre läkare och nio sjuksköterskor från akutvårdsavdelning med inriktning infektion, mottagning med akutintag och akutmottagning. Analysarbetet genomfördes med Malteruds (2009) innehållsanalys. Resultat: Vårdplatssituationen kommer sig av en brist på vårdplatser inom främst medicindivisionen, samt en oförmåga att hålla de platser som finns öppna på grund av sjuksköterskebrist. Bristen på vårdplatser har inneburit en oförmåga för läkare och sjuksköterskor att utföra sitt arbete i enlighet med sin kompetens och beprövad erfarenhet.Slutsats: Svårigheterna med att finna platser till patienterna på deras hemavdelningar samt de ständiga omflyttningarna av patienter medför svårigheter för vårdpersonalen att ge god medicinsk vård och omvårdnad vilket medför stora risker för patientsäkerheten.
Avel för hållbarhet och livslängd hos köttdjur
The purpose of this literature study was to investigate the possibilities to improve longevity and stayability of beef cattle with breeding. The breeding goal for beef breeds is to produce animals with high capacity for growth and good feed efficiency. Longevity and sustainability are two important features to include in the breeding goal. If longevity is increased each cow can produce more calves and the number of female calves used for recruitment can be reduced and only the best heifers need to be selected for breeding. The benefits of longer life is that it lowers the costs of recruitment animals, it increases the number of young animals that become available for slaughter, and it increases the proportion of high producing animals in the herds.
Ekonomiska sanktioner ur ett sjömaktsteoretiskt perspektiv
Fleets have the ability to affect an adversary?s use of the seas for transportation. Nations have in numerous occasions exercised this power in order to ravage their opponent?s trade in times of conflict with the purpose of diminishing their military might. Great naval thinkers like Mahan and Corbett have described this use of seapower during conflicts in great depth but theories regarding the use of seapower to affect a nation?s peacetime economy in order to achieve limited political goals is lacking.
Högskolebiblioteket i den pedagogiska processen
The information society creates new demands on the knowledge making individual; besides being literate one has to be information literate. And in the educational society there is an ongoing change from teaching to learning, the focal point being the active student and life long learning. The aim of this dissertation is to within a context of learning and teaching elucidate the relation between user education and subject education by examining what significance the academic libraries user education has for the development of information literacy within students. Some epistemological theories connected with learning is presented as well as aspects of the information search process and of information literacy. Universities and their libraries view of information literacy and the goal of their user education is being focused on in an empirical study.
Mot en hållbar utveckling : Vad motiverar företag att arbeta för en bättre miljö?
De negativa klimatförändringarna är 2000-talets stora moraliska dilemma. Transportsektorn bidrar idag med cirka 27 procent av världens alla utsläpp. Därmed kan det finnas ett stort utrymme för branschen att minska sina utsläpp och därmed sin miljöpåverkan.Syftet med denna studie är undersöka vad som motiverar företag att ta hänsyn till miljön i sina beslut, dagliga som långsiktiga strategiska beslut.Studien är genomförd med en kvalitativ ansats och data har samlats in genom semistrukturerade intervjuer med 8 företag. Samtliga företag är verksamma inom transport- och logistikbranschen.Studien visar att majoriteten av de undersökta företagen idag arbetar med att förbättra miljöprestandan, och en stor del av det miljöarbete som företag gör bottnar i en strävan efter ökad lönsamhet. Företagen förklär sina effektiviseringsåtgärder med en ?grön exteriör? som kommunicerar miljöarbetet.

Övervakningssystem för båtelektronik
Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.
Teoretisk och experimentell utvärdering av Lättelement AB:s takinfästning
Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.
Återförvilda Sverige?: En studie av rewilding som strategi för att bevara kulturlandskapet och gynna biologisk mångfald
Through millennia, humans have shaped the European landscapes. Agriculture, hunting andforestry have influenced virtually every ecosystem on the continent and formed what we todaythink of as the cultural landscape; a mosaic pattern of cropland, fields, pasture and forests. Thepast two centuries, globalization, industrialization and urbanization have come to pose a threatto the existence of these landscapes. European farmlands are now being abandoned at analarming rate, and the associated loss of landscape preservation, biodiversity and ecosystemservices is a concern to the scientific community and public alike.This thesis studies if the implementation of the relatively new conservation strategy rewilding(recreating self-sustaining ecosystems and reintroducing keystone species) can be a part of thesolution to preserve cultural landscapes and biodiversity in Sweden. Through interviewssupplemented with studies of published works, expertise from different fields has beencompiled to provide an overall picture of the capacity of rewildings as conservation method.
