Simulering av översvämningar i Byälven
Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

Sjuksköterskors kunskap om och attityder till undernärng
ABSTRACTBackground and aims: Nutrition is a part of the medical treatment, and also a part of the nursingcare. In spite of this, malnutrition is a common problem in the health care sector. Studies show thatnurses have too little knowledge about nutrition and malnutrition and that nutrition has low priorityin the daily work. The aim with this study was to find out the nurses self-reported knowledge aboutand their attitudes towards malnutrition, nutrition screening, prevention and treatment of patientswith malnutrition.Methods: A questionnaire was handed out to 65 nurses in two different care units and 36questionnaires were answered.Results: The respondents from the two care units self-reported their knowledge about nutrition andmalnutrition low. Most of the respondents stated to have a big need of education about nutritionscreening and more than half of the respondents stated that they have a need of education forprevention and treatment of malnutrition.
"... människan kan förändras om man ger den verktyg" - En kvalitativ studie av elva frivårdsinspektörers synsätt på kontraktsvårdsutredningar för drogmissbrukare
The object of this essay was to illustrate and analyse what determines that a contract treatment investigation for a drug addict is initiated and what factors influence the investigation itself, from the probation service officer's perspective.We selected the following two questions:- What does the probation service officer see as being the deciding factor for a contract treatment investigation to be initiated?- What questions appear in a contract treatment investigation and how do they influence the investigation, according to the probation service officer?To find answers to these questions we conducted interviews with 11 probation service officers, during November and December 2005, at three different locations across Skåne. We decided to use the qualitative method for collecting the data we needed.In our essay we came to the conclusion that the will and motivation of the client is a deciding factor whether or not a contract treatment investigation is to be initiated. An important collaborator in this process is the social services. According to the probation service officers, many of the problems that may appear in the co-operation are due to the tough economic constraints experienced by the social services.
Konduktivitet i vattendrag som indikator på sura sulfatjordar
Increasing attention is being given to acid sulphate soils wherever they occur. The problems that leaching sulphate soils gives with significant lowerings of pH and mobilization of heavy metals influence large spectra of our society from fisheries to agriculture to construction. Mapping these soils is consequently of great importance and the methods of doing this is very much lacking in function and precision. This study was therefore carried out to investigate whether conductivity in running water can be used as a simple instrument to identify acid sulphate soils in the catchment. 31 coastal streams in the county of Västerbotten were analyzed for different catchment properties such as occurence of marine sediments and basic water chemistry including conductivity and sulphate.
Värmeåtervinning ur spillvatten i befintliga flerbostadshus
Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.
Mineral composition of New Zealand monofloral honeys
The objective of this study was to determine the mineral content in ten New Zealand monofloral honeys, in order to distinguish whether New Zealand monofloral honeys are a good source of minerals compared to honeys from other parts of the world. The ten monofloral honeys were collected from a local honey factory (Airborne Honey Ltd, Leeston), Clover, Honeydew, Kamahi, Manuka, Nodding Thistle, Rata, Rewarewa, Tawari, Thyme and Vipers Bugloss honeys were been investigated. The water content, water activity, pH, conductivity, colour and mineral content were evaluated. The water activity was averaged for all the ten New Zealand monofloral honeys and set to 0.59 aw, which indicates a high stability and long shelf life as a food stuff. A strong correlation between total mineral content, pH, conductivity and colour was obtained.
Kränkande behandling via sociala medier : En kvalitativ studie om skolpersonalens syn på kränkande behandling via sociala medier
The aim of this study is to examine if and to what extent the personnel at the local school perceive offensive treatment through the social media among the students and what the personnel thinks about the responsibility of the school to prevent this type of abuse. Offensive treatment through the social media has become a common occurrence among youth and affects health in both psychological and physical ways. As offensive treatment through the social media often takes place outside of school in the students spare time the responsibility of their health is unclear. But since it affects their school results the school has a responsibility to act, which is confirmed by legislation. However, the legislation does not mention offensive treatment through the social media and the school has no distinct guidelines to prevent this form of offensive treatment.
Fånggrödor i Norra Östersjöns vattendistrikt
70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the
requirements for good ecological status. This is mostly due to eutrophication caused by a too
high deliverance of nutrients from agricultural land or effluents. Losses of particulate
phosphorus through water erosion contribute to a great extent to this eutrophication. In the
action plan for the water district cover crops are mentioned as a measure for reducing losses
of phosphorus from arable land. This paper reviews the possible effect of cover crops in the
water district and discusses what crop that would be most suitable.
Spillvärmeåtervinning
SAPA´s resource of waste heat is the basis for this thesis to investigate the possibility of energy assets in their cooling water and possible uses for it. The energy in the waste water is greater than the current need which has three uses which are (1) heating the factory, (2) converting liquid propane to propane gas and (3) local domestic heating. The average energy load that is available is 1, 7 MW and the average temperature in the cooling water is 41°C. The total energy load at dimensioning out side temperature is approximately 1,6 MW for the three current uses. The temperature is currently too low to be used directly in the existing systems so an upgrade is needed.

"Jag Liksom står väl på mig" : - en studie om sex personer med funktionsnedsättningar och deras upplevelser av bemötande i kontakten med handläggaren inom den offentliga sektorn.
Treatment is both about the actual encounter and how individuals interact as well as the behaviour among the counterparts. Previous research shows that a person?s experience of how he/she is being treated is formed by conditions created by external factors, in literature known as the general view on treatment. The purpose of the study is to show how people with a physical disability experience the treatment from their Social Security Agency administrators. We have compared the empirical material with theories on treatment and power and analysed how this affect the interaction between the administrator and the disabled person.
Ett arrogant regelverk. En studie om hur vårdgivare inom läkemedelsassisterad behandling vid opiatberoende ser på och hanterar Socialstyrelsens föreskrifter.
The purpose of this study is to describe and analyze how health care providers, working at care facilities providing maintenance treatment programs for opiate dependence, perceive and manage the legal framework governing the treatment. The study is limited to a few particular rules within this framework which over the recent decade have been the subject matter of debate regarding i.a. their alleged lack of relation to scientific research and their frequently disastrous implications for program participants. The empirical material consists of interviews with five respondents working at four different care facilities and has been analyzed by using Lipskys theory on street-level bureaucrats as policymaking agents. The results of the study show that the rules are looked upon and dealt with in a liberal fashion and that the primary loyalty of the maintenance treatment staff is clearly directed towards promoting the well-being of their patients and helping them reach their treatment goals rather than strictly following the rules..
Geotermisk fjärrvärme i Gunsta
Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW.
To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.
