Alternativ till kreosotimpregneradestolpar i Vattenfalls elnät i Sverige
Då ett eventuellt förbud av nya kreosotimpregnerade stolpar kan bli en verklighet inom EU år 2018 letar Vattenfall efter andra alternativ. Stål, betong, limträ och komposit anses idag vara de mest konkurrenskraftiga alternativen och kommer att undersökas i denna rapport. Grundläggande tekniska egenskaper, miljöutsläpp och kostnader för de olika stolptyperna kommer att analyseras i rapporten och jämföras mot den kreosotimpregnerade furustolpen. Rapporten beskriver hur de olika stolpalternativen lämpar sig i Vattenfalls elnät i Sverige.P.g.a. sekretesskäl kommer exakta prisuppgifter inte att redovisas.
Potentiella armeringsfel inom byggproduktionen : En generell studie
Reinforcement is of great importance to fulfill the dimensioned strength of a concrete construction. This requires that the work needs to be carried out with adequate results that neither endangers the workers or the safety of the construction. Progressive development of the planning phase, construction documents, and construction methods is in constant need since the technology constantly evolves.In order for contractors to be able to get acceptances from their quotations requires that they have to increase their working pace in order to be able to leave a quotation with a lower price than the competition.Due to the increasing pace the different parts involved in the construction process is subjected to time pressure. The design stage, construction documents, work preparation and the execution are all affected when everything has to be finished quickly. To avoid problems, it is required that all parts are able to deliver good quality solutions and results under the influences of time pressure, which is not always easy.
Vad kostar en endemi? - Kartläggning, Resurshantering och Policyutformning av malariaproblematiken i Tanzania
Uppsatsen behandlar malariaproblematiken i Tanzania. Den syftar främst till att kartlägga de insatser som gjorts för att förhindra framfarten av malariarelaterad mortalitet hos barn under 5 år. Vitala aspekter i kampen mot sjukdomen är en effektiv Distribution av myggnät behandlande med insektsdödande gifter till gravida kvinnor och spädbarn vilka löper störst risk att drabbas av sjukdomen på grund av nedsatt immunförsvar.De ekonomiska implikationerna av malaria är dramatiska och drabbar det enskilda hushållet hårt, framförallt genom dess dramatiska reducerande av individens humankapital.I Tanzania kom dylika insatser i gång ordentligt först i början av 2000-talet. Brist finansiering för malariakontrollprogram tillsammans med utbildnings och informationsrelaterade implenteringsproblem har lett till att man ännu inte kunnat skönja några direkta positiva resultat i termer av sjunkande mortalitets siffror.En kontinuerlig ökning av likvida medel, dramatiska ökningar av förekomst av nät i Tanzaniska hem samt en bättre generell kännedom om sjukdomen och vad man som hushåll kan göra för att minimera riskerna har lett till förhoppningar om att resultat snart kommer tydliggöras. Från regeringshåll har en effektivare hälsorelaterad policyutformning tillsammans med tydliga strategiprogram för kontrollerandet av sjukdomen, speciellt i avseende på effektivt utnyttjande av biståndsmedel, ytterligare bidragit till att malariaproblematiken i landet verkar vara på väg att stagnera och avta..
Utlandsrekrytering: Hur organisationer anpassar sin kompetensförsörjning samt vilken funktion Eures fyller
Demografiska förändringar i form av en åldrande befolkning kommer att medföra att andelen arbetande minskar samtidigt som andelen icke arbetande ökar vilket leder till en arbetskraftsbrist i Sverige. Ett sätt att lösa bristen är att öka arbetskraftsinvandringen. Arbetsgivare har redan nu svårt att hitta den kompetens de letar efter inom landets gränser, men till deras hjälp finns nätverket Eures vars uppdrag är att underlätta för matchningen av arbetskraft inom EU/EES och Schweiz. Då konkurrensen om arbetskraft är hög krävs att organisationerna anpassar sin kompetensförsörjning för att kunna attrahera arbetskraft. Studien syftar till att undersöka hur organisationer anpassar sin kompetensförsörjning genom att utlandsrekrytera samt utreda vilken roll Eures spelar för organisationerna.Syftet undersöktes genom kvalitativ metod där sex intervjuer genomfördes med personer som utlandsrekryterat.
Det bästa av två världar : Könsfördelningen inom Human Resources branschen utifrån det mjuka och hårda HRM-perspektivet
Human Resources (en benämning för personalarbetet) är ett yrke som idag blir allt populärare. Trots detta visar statistik att en majoritet av kvinnor både studerar och arbetar med personalfrågor. Studien har därför som syfte att undersöka varför Human Resources branschen har en ojämn könsfördelning. Detta görs genom en historisk inblick i branschens utveckling i relation till samhällets förändringar, där en analys av texter ger en bild av dagens personalarbete. De teoretiska utgångspunkterna består dels av socialkonstruktivism och dels av begreppen mjuk och hård Human Resources Management.
Barley starch, structure and properties
Starch is a naturally occurring substance in most plants and is used as energy storage. It is a component that mainly consists of amylose and amylopectin. Together they build a complex pattern which gives starch its specific properties. The proportion of amylose and amylopectin varies in different plants but generally starch consists of 25 % amylose and 75 % amylopectin. There have been discoveries of barley varieties containing 100 % amylopectin called ?waxy starches? or ?waxy barley? as well as varieties that have a high content of amylose, around 70 % and these are called ?amylotypes?.
Dynamiska egenskaper hos håldäcksbjälklag belastade med gångtrafik
Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.
Dog bite incidence and associated risk factors : a cross-sectional study on school children in Tamil Nadu
Dog bites pose a threat to public health globally and can lead to infection, disfigurement, incapacity, post-traumatic stress syndrome and even death. In geographical areas where rabies is endemic, bites from infected dogs account for over 90% of the human rabies cases.
Children have been proven to be at a greater risk of being bitten by dogs and subsequently contracting rabies than adults. In this cross-sectional study, a school survey was undertaken in association with a rabies awareness campaign in India, to investigate the dog bite incidence and various risk factors associated with dog bites as well as assessing the knowledge of safe interaction with dogs among children in the age group 10-18 years. A total of 1295
questionnaires were collected. 43.2 % (n=556) out of the respondents were boys and 56.8 % (n=731) were girls with a mean age of 14 years.

GIS-baserad habitatmodell för mindre hackspett, ett verktyg för att bevara skyddsvärda lövskogar inom Umeälvlandskapet :
Deciduous forests are, according to the National Environmental Quality Objectives, a priority area. Deciduous forests are rich in species and the occurrence of dead wood is an important factor for biodiversity. In order to identify valuable deciduous forests for bio-diversity, conservation needs good analyses and planning tools. Habitat models combined with geographic information systems can be used to study the spatial structure of suitable habitat. The Lesser spotted woodpecker (Dendrocopos minor) has been proposed as an indicator species for deciduous forests, since this species is highly specialized on insect larvae in dead wood and requires large areas of deciduous-rich environments.
Many riparian forest with high species richness and high nature conservation values are found along the Ume river in Umeå municipality.

Kastanjemalen Cameraria ohridella : livscykel och utbredning i Sverige 2006
Cameraria ohridella, the chest-nut leaf miner, is a new pest in Sweden. These moths make leaf mines on chest-nut trees, preferably on Aesculus hippocastanum, which results in brown blotches on the foliage and early loss of leaves. Since the first observation in Macedonia in 1985 it has spread rapidly through Europe. The moth arrived in Sweden in 2003 when it was observed in Malmö and surrounding areas.
In this paper a literature study describes the morphology and life cycle of the chest-nut leaf miner. Further more a test with pheromone traps examining the number of generations in Sweden is shown.
Landskapsplanering ur ett hållbarhetsperspektiv :
Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.
Utveckling av Innovativa Småskaliga Elförsörjningskoncept : - Minor Field Study i Namibia
A large part of the Namibian low income population lack access to grid distributed electricity. This mean they are effectively shut out from basic functions such as lighting, information technologies and hygienic food handling. Hence, finding ways of providing affordable off-grid electricity is an important, not to say critical, task.This master thesis is an innovation and concept development project that has been carried out in cooperation with organisations in Sweden and Namibia. The purpose of the project has been to (1) develop a concept for off-grid electricity supply in Namibia and (2) to gain a deeper knowledge within the area of innovation and product development for the Base of the Pyramid population, i.e. the poorest, but largest, socio-economic part of the global population.Essential in this project has been to acquire user understanding and to identify user needs to create a foundation for developing the concept.
