Berättelser från kommunikativa mellanrum - Om socionomstudenters erfarenhetsbaserade lärande i projektet Unga möter Unga
In recent years there has been a growing interest directed towards focusing on the importance of clear evidence for interventions in social work. To enable the measurement it?s necessary to develop concrete models with manuals on how social work should be designed. Evaluation of the benefits is made in relation to how well the method can detect evidence of clear measurable results. When measuring the result it?s of importance to emphasis on pre and post the situation, not the situation where social work takes place.
Identifiering av områden med risk för fosforförluster genom ytavrinning : metodutveckling med GIS
The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.
Sponsring i Sverige
The purpose to this study is to find an understanding of the effects of how sponsorship can affect companies and their business and at the same time get a better understanding of how sponsorship is or can be used as a marketing tool in today?s marketing. By using a quality research method we have chosen to use a half structured research method to make it possible to find out how sponsorship as a marketing tool can be used from a company perspective in relation to our chosen thesis. To enhance the readers understanding we describe the base of sponsorship and principals for sponsorship, after that describes a deeper perspective of sponsorship, what sponsorship is, and what factors are needed to be taken into consideration. Further on we illustrate the figure that later on will constitute the analysis with attributes like: association, exposure, relations and integrated communication.
Survey of Fusarium species on yellow onion (Allium cepa) on Öland
It has been observed by both onion producers and a plant protection advisor on Öland (an island off the east coast of Sweden) that basal rot is the largest contributory factor to reduced onion quality and yield. Basal rot is mainly caused by species of Fusarium fungi. The aim of this study was to: a) investigate which species of Fusarium that can be found in onion produced on Öland, b) describe the symptoms caused by the different Fusarium fungi found and c) explore, through interviews with the onion producers on Öland, the mechanisms that may be involved in the observed increase in basal rot.Onion bulbs (Allium cepa) were sampled on two occasions. In total 181 onions from 11 different fields were analysed. In addition, eight onion producers were interviewed.
Corporate Social Responsibility : -Kan det bidra till demokratisering?
There is a growing awareness that multinational companies have opportunities to influence political conditions. Ethical activities made by multinational companies and ?Corporate Social Responsibility? (CSR) can therefore function as a positive input in society. The primary purpose of this master thesis is to investigate CSR´s contribution to strengthen human rights, and thereby to democratization. The research questions are listed below:1.
BIM i produktionsskedet
This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

The project was initiated by Medipharm which produce microbial inoculants which used
as additives to preserve forage. The main goal was to test three inoculants to produce
maize silege. The following Medipharm produced inoculants were tested, Milab 393,
Lactisil Wolecrop II, Lactisil 300 2. An untreated control was included in the study. The
trial was done at Swedish university of Agriculture and Science in Alnarp, Sweden.
Eurostar was the cultivar of the maize and was grown on 20, 5 hectares.
TILLFÄLLIGA EFFEKTTOPPAR I FJÄRRVÄRMEN : Kan man med hjälp av lagrad värme undvika att de uppstår i betonghus?
Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.
Transporttidsmodellering vid provpumpning i heterogen jord : spårämnesförsök i en isälvsavlagring
When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.
XRF-analys av förorenad mark : undersökning av felkällor och lämplig provbearbetning
X-ray fluorescence (XRF) detection of heavy metals is a cost- and time-effective method for investigation of polluted areas. Compared to laboratory analysis, XRF analysis is limited by high detection limits and uncertainties in some situations. Preparation of samples is known to affect the results of measurements.The purpose of this thesis is to bring a deeper understanding of how different factors affect the results of XRF-analysis. A large number of measurements have been made with the instruments Niton XLt 700 and Niton Xli 700. Results from measurements of lead, zinc and copper have been analysed.This study has shown that a greater moisture content will give a lower measured concentration for the same sample.
Utvecklingsprojekt Easy Load
In order to increase the independence in everyday life of the elderly population, we have developed a lifting aid for loading in the private car trunk. Independence from outside assistance affects self-esteem in a positive direction and can help increase the quality of life for a large group of individuals. As people age and experience changes in performance, it is important that aids and support is available, particularly to reduce the experience of aging and it?s increasing physical limitations. The aim was to develop a function prototype characterized by simplicity, which facilitates loading of the private cartrunk.The project was conducted at the request of Autoadapt AB, which is one of the leadingactors in car adaptations for individuals with disablilities.
Skogen Brun : ett nedslag i västsvensk skogshistoria
After the last is age there was a long period when there was no shortage of forest for peoples needs. People living in Sweden could use the forest resources at their will. Around 4000 years BC the inhabitants of southern Sweden started to use the agricultural system and people become more stationary. The farms were located together in groups and together they formed a social association, the village. Successively the population grew and in some areas the forest started to become a finite resource.
Renovering av utanpåliggande balkonger
Balkonger har funnits i Sverige i över 200 år och är nu på modet. De är i allmänhet utsatta för stora påfrestningar och orsakar ofta en vanlig typ av köldbrygga. I synnerhet de balkonger som byggdes till flerbostadshus i betong under miljonprogrammet måste renoveras. De är byggda med dåtidens teknik vilket innebär att de bildar en köldbrygga.Denna rapport är till för att vägleda fastighetsägare vid en renovering av utanpåliggande balkonger i betong. Metoder på marknaden har undersökts med hjälp av intervjuer och litteraturstudier.
Konceptstudie av drivmodul till bandskotare med hybriddrift
BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.
En arena för alla? : En studie om normbrytare på Stockholms stads idrottsplatser
In Stockholm there are currently five women, out of a total of 102 employees, working in public sports arenas. In sports arenas men are numerically superior amongst the workers as well as the visitors. These arenas are in many ways male dominated, masculinized environments. In this essay I investigate the reasons behind the uneven distribution, in terms of gender, among sports arena workers. I do this by interviewing seven female sports arena workers (the five current and two former), and by observing their workplaces.
