The potential microbial risk from using treated wastewater is a burning issue to be studied. In Sweden, only a small part of treated wastewater is reused directly, although water reuse could be beneficial. Disinfection is virtually never practised and no protective guidelines for water reuse are found in Sweden. Based on a 1 year monitoring programme of water quality, this paper estimates the micr
There is a need for integrated care and smooth collaboration between care-providing organisations and professions to create a continuum of care for frail older people. However, collaboration between organisations and professions is often problematic. The aim of this study was to examine the process of implementing a new continuum of care model in a complex organisational context, and illuminate so
The purpose of this project was to investigate the possibilities to manufacture wet-glued laminated beams for load bearing applications from Norway spruce side board lamellae and by that achieve products that are difficult to obtain from the centre yield of a log and also contribute to increased profitability in the sawmill industry.
Properties such as shape stability, strength an
En enkätundersökning har genomförts bland brandingenjörer i Sverige med syftet att få information om detektionstider samt reaktions- och beslutstider vid en utrymning av tre olika lokaltyper; varuhus, restaurang och danslokal/nattklubb. Reslutaten kan ligga till grund för fortsatta studier för att bestämma partialkoefficienter för dimensionering av de gångvägar som används vid utrymning. Den ger o
Popular Abstract in Swedish Gasturbiner har länge varit en ekonimsk och driftsäkert sätt att producera energi. Främst har dom använts för framdrivning av flygplan och production av elektricitet och värme. Dom ständigt ökade kraven på miljöfarliga emissioner har tvingat fram nya metoder för att producera kraft. Nästa generations kraftverk måste ha hög termisk verkningsgrad samt mycket låga emissionGas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. The requirements for these new power cycles are substantially better emissions, hig
To enhance the performance of gas turbine engines, high top-cycle temperatures are desired. However, the temperature is limited by current materials. To achieve the higher performance, and meanwhile maintain the metal temperatures of the combustors, vanes and blades below the allowable limits, sophisticated cooling techniques, such as impingement cooling, film cooling and convective internal cooli
A naturally contaminated sediment was partially extracted with selective supercritical fluid extraction (SFE) to remove a fraction of supposedly bioavailable PCBs from the matrix. Eels (Anguilla anguilla) were cultured in systems with untreated and pre-extracted sediment, respectively, and it was shown that the SFE treatment selectively removed bioavailable PCBs from the sediment, since relative b
A large gravel pit 30 km north of the Pomeranian ice margin has been investigated. Besides gravel, sand, fines and diamicton, several deposits of organic material are present, some of them showing a typical Eemian Pollen- and macroflora. Previous interpretations assume that the sediments below the Eemian peat belong to the Saalian, and those above the peat to the Weichselian. Sorted sediments in t
During the last few years the home care services have had to face an increased responsibility for medical tasks. A study in the city of Malmö in 1993, repeated in 1998, shows that 95% of the health care assistants are engaged in the administration of medication. The studies demonstrate that health care assistants have inadequate knowledge not only about medicines and their administration but also
A mixed initial-boundary value problem for a nonlocal, hyperbolic equation is analyzed with respect to unique solubility and causality. The regularity of the step response and impulse response (the Green functions) is investigated, and a wave front theorem is proved. The problem arises, e.g., at time-varying, electromagnetic, plane wave excitation of stratified, temporally dispersive, bi-isotropic
The aim of this essay is to explore the possibilities of achieving a stronger local democratic establishment. Research shows that the welfare gap between population groups and city districts are growing within societies. Citizens are also experiencing a decreasing trust in politicians and the participation in elections and party politics is decreasing. Therefore I find attempts to increase local d
Demokratiska Republiken Kongo är ett land med en synnerligen blodig historia med upprepade övergrepp, krig och interna etniska motsättningar. Det senaste kriget där både interna och externa aktörer stred är formellt avslutat sedan 2003 men väpnade konflikter pågår fortfarande i delar av landet. Över fem miljoner människor beräknas hittills ha omkommit och miljontals lever som internflyktingar. Båd
Studiens syfte var att nå en fördjupad förståelse för vilka faktorer som kan främja respektive hindra återgång till arbete vid en sjukskrivning för stressrelaterade besvär. Semistrukturerade intervjuer genomfördes med tio individer som genomgått behandling vid Alnarps Rehabiliteringsträdgård, en verksamhet som riktar sig till personer som drabbats av stressrelaterad ohälsa. Materialet analyseradesThe aim of this study was to reach a greater understanding of the factors that can promote or prohibit return to work after a sick leave due to stress-related illness. Semi-structured interviews were conducted with ten individuals who had undergone treatment at Alnarps Rehabiliteringsträdgård, a rehabilitation program for people suffering from stress-related problems. The data was analyzed by use
MMORPGs has become a growing phenomena in our society today. Many people interact online in virtual communities such as World of Warcraft. In this study, the goal was to explore the game's significance for young adults and the relationship these people have to the game. This thesis is based on five interviews with young adult users and their life around WoW. The reason for the study was to obt
This report summarizes the classification systems for surface lining materials in Europe and Japan. There is also a part including a discussion on differences, similarities and possible ways to link the two different systems together. In June 1994, an important agreement was made between the member countries in the European Community. The agreement stated that all member countries should have the
This report is about how to predict the none-thermal damages from soot and hydrogen chloride on metallic surfaces and electronics. The models described are C-Fast and ’A Probabilistic Methodology For The Fire Smoke Hazard Analysis Of Electronic Equipment’. The models can only be used for special conditions and they demand some knowledge from the user.
Smoke spread via ventilation systems relying on running fans or bypasses can be calculated with performance based fire safety analyses tools. The focus of this thesis work was to review existing methods for treating this problem and to further develop current analysis methods. Suggestions are also made for setting up guidelines as to what are tolerable amounts of smoke spread depending on building
The Swedish district heating market is becoming increasingly saturated, whilst the UK heat market is about to run into copious turmoil due to the faltering and decreasing levels of natural gas available. Swedish companies are looking to enter new market segments, and there seems to be something stirring under the surface in terms of district heating in the UK. The development of district heating i
