Sedimentprovtagning av dagvattendammar som ett alternativ till flödesproportionell vattenprovtagning
Stormwater run-off from surfaces such as roads or rooftops is often polluted with heavy metals and nutrients. Many of these substances can cause great damage in biota if they end up in the recipient. In Sweden constructed wetlands and ponds for treatment of stormwater are frequently used, since research has shown that these treatment ponds are reducing stormwater pollution considerably to a low cost. The knowledge of these pollutant removal mechanisms and how follow-up and assessment of the ponds should be performed is still limited.To determine the pollutant removal efficiency of the stormwater ponds it is recommended that flow-weighted water samples are collected from both the inflow and the outflow of the pond. This method demands considerable resources of time and money for installations and analysis.
Lärplattformar : En fallstudie av lärplattformarna vid Umeå universitet
Umeå University currently uses two Course Management System, Moodle and Sakai (Cambro). Both Moodle and Sakai are based on open source code and are today the two more popular choices among Swedish Universities. They both have different strengths and weaknesses both from a technical perspective and a user perspective. This can create problems for a course responsible/teacher when it comes to planning the course structure at a distance course but also when planning the course structure on a campus course that uses a Course Management System. With this as my starting point my formulations of questions become:How do the Course Management Systems that Umeå University uses differs, both from a technical perspective and user perspective?What possibilities is there in the Course Management Systems to use a different Course Structure?Is there a noticeable difference on the view of Course Management System of teachers and students at different departments?The purpose with my essay is to create a basis that course responsible/teacher can use to plan the course structure.

Fysisk aktivitet som fallprevention i särskilt boende - en litteraturstudie
Our population are ageing. As this happens more people will be in need of long
term care facilities. We now know that some elderly people with certain
background factors are more likely to be injured or sick. One of the four biggest
background factors is fall propensity. Most of the reported falls come from long
term care facilities, approximately 60 % of the care takers in long term care
facilities fall one time or more each year.

Special attention is put on analyzing how the monthly fee and the location affect the price. The hypotheses are that the monthly fee and the distance to the central part of the city have a negative effect on the price. A number of additional price affecting factors was taken in consideration during this study.MethodThis study is mainly based on data supplied to us by Mäklarstatistik. The supplied data consists of information about tenant-owner apartment sales in Uppsala during a year under 2008 and 2009.
Överföring av radiocesium till potatis vid olika nedfallstidpunkter :
Agricultural land could be polluted by radioactive substances after a fallout. We would then need information about the level of contamination to decide whether the crops could be utilized as food under these circumstances. In an experiment carried out during the 1990ies the retention of 134Cs in potato haulm and the transfer to the tubers were studied. The experiment was carried out during three consecutive years. The plants were cultivated in pots under field conditions and the artificial deposition was sprayed directly onto the potato haulm at different times during the growing season.
?Vem behöver anledningar när man har heroin?? ? En kvalitativ studie om socialsekreterarens erfarenheter av motivationsarbete med heroinmissbrukare ur ett förändringsperspektiv.
The purpose of this essay was to examine the different aspects of motivational work with active heroin-using clients from a social workers point of view. The further purpose of this essay is to also examine what the advancements and discouraging factors in such a motivational work might be. To attain this purpose we focused on these following questions:What might motivational work with active heroin-using clients look like?According to the social worker, what factors constitutes for a beneficial progress in the engagement of motivational work with active heroin-using clients?According to the social worker, what constitutes for discouraging factors in the engagement of motivational work with active heroin-using clients?We chose to do a qualitative study by conducting separate interviews with six social workers working in a social services agency, all of whom are working with drug-addicted adults. We then analyzed the answers by using an abductive research strategy, testing the collected empirical data against our chosen theoretical perspectives.
Partneringupphandling inom anläggningssektorn : Kommunernas intresse i Mälardalen
Partnering is a collaboration method where the contractor and the client work together, based on a mutual trust towards each other and with a common goal for the project. The method originates from the United States where it was early adapted by the U.S. Army Corps of Engineers. It later spread internationally where the United Kingdom and Denmark were early in Europe to see the potential with partnering, to help aid with the issues they were having where construction projects kept running late, going over budget and lacked in quality. By using partnering you can achieve a shorter building time, improved work relationships and enhanced efficiency and cost effectiveness.
Effekter av evenemang för lokala företag : En fallstudie av Skidskytte-VM i Östersund 2008
Evenemang är för många nationer och orter idag ett prioriterat område. I Sverige anses evenemang vara ett viktigt utvecklingsområde och en möjlig tillväxtgenerator för turismnäringen. Hur evenemang påverkar lokalsamhället och vilka effekter de får för det lokala näringslivet på en arrangörsort är områden där det behövs mer kunskap. Detta för att skapa rimliga förväntningar på evenemangets effekter och för att veta vilken nytta ett evenemang egentligen har för lokala företag. Syftet med denna studie är att undersöka effekter av evenemang för lokala företag.
Grovkrossning av stubbar : en produktivitetsstudie
The Swedish parliament has decided that Sweden should increase its usage of renewable fuel sources to a level of 50% of the total energy consumption in Sweden by the year 2020. One way to reach that goal may be to increase the usage of stumps as a bio-fuel. In Sweden stump harvesting is possible on about 5-10% of the total harvested area and thus contribute with 1,3 - 2,6 TWh per year. An increase stump harvest doesn't come without its drawbacks for the environment. When harvesting stumps a tracked excavator is used to pry the stumps from the ground and then cut the stumps into smaller pieces.
Moibl interaktion i kollektivtrafik
In this paper we take a look at digital applications to help the user with public transportation. The main goal was to evaluate the problem a user can face when aiming to use the public transportation system, and to create a application for Apple Iphone that can enhance and help the user, no matter if he is familiar with the local public transportation system, or if he is less familiar with it. The aim was that the user wouldnt need any previous knowledge to be able to use our application. We combined Location-Based Services with Realtime-travelinformation and trip planning to examine if this combination could make both of the two different user-groups satisfied. To understand the problematics a user faces when approaching the public transportation-scene, Scenario-Based Design is evaluated as a method to grasp this problem.
Factors affecting bark-stripping by red deer (Cervus elaphus) : the importance of landscape structure and forage availability
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.
Optimal inkalvningsålder för rekryteringskvigor till mjölkproduktion : relaterat till data ifrån egen besättning
Heifer?s growth may be divided into three main phases: calf period, puberty and pregnancy. When the heifers are about three months old a critical period begins. This period ends when the heifer reach puberty and have her first oestrus at around 9-12 months of age. In the critical period the mammary gland starts to grow at a fast rate and Insulin-like growth factor-1 (IGF-1) transport the growth signals to the mammary glands.
Betydelsefull närhet och nödvändig distans : Sjuksköterskans professionella förhållningssätt inom palliativ vård
Palliativ vård innebär ett förhållningssätt där patientens livskvalitet står i centrum. Vården kännetecknas av en holistisk människosyn där patientens fysiska, psykiska, sociala samt existentiella behov ska tillgodoses. Från sjuksköterskans perspektiv kan palliativ vård bedrivas inom såväl primärvård som slutenvård och omfattningen av det palliativa vårdandet varierar beroende på inom vilket område sjuksköterskan är verksam. Oavsett kontext har sjuksköterskan en relationsskapande funktion och relationen har stor betydelse för patientens välbefinnande. Professionell hållning inom palliativ vård innebär att sjuksköterskan medvetet tillämpar ett empatiskt förhållningssätt.
Utvärdering av dimensionell stabilitet i PWR-patroner i Ringhals
Dimensional stability is an important aspect of fuel mechanical design and licensing of new fuel designs for nuclear power plants. Dimensional changes within the reactor can affect the safety margins against overheating of the cladding and the pellets, therefore it is crucial that the dimensional changes are kept to a minimum.The profits per produced kiloWatt hour continue to decrease for the Swedish nuclear power plants. Some reactors are even operated with a calculated loss. To reduce fuel costs and thereby improve the profit some reactors are operated with higher uranium enrichment, so that the assemblies can reach a higher average burnup. This increases the neutron fluence to the pellets, cladding an spacers.
