1. 1. Application of Mathematical Programming to Short-Term Operation Planning of Hydrothermal Power System

   Författare :Hooshang Habibollahzadeh; Janis Bubenko; Denis Sjelvgren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydro power; Optimization; Short-Term Operation Planning; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The thesis contains the results of a reseach project on application of mathematical programming methods to short-term operation planning of large hydrothermal power systems. The project was aimed at devoeloping efficient solution techniques that are practially applicable to large systems. The problem is modeled as a large mixed integer program.. LÄS MER

3. 2. Oral health, experiences of oral care, associated factors, and mortality among older people in short-term care

   Författare :Susanne Koistinen; Anna Ehrenberg; Lena Olai; Katri Ståhlnacke; Ulrika Lindmark; Högskolan Dalarna; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; older people; oral care; oral health; oral health-related quality of life; self-perceived; short-term care; swallowing dysfunction; mortality; Health and Welfare; Hälsa och välfärd;

   Sammanfattning : Objective: The overall aim of this thesis was to describe oral health and oral health-related quality of life (OHRQoL), to compare self-perceived oral health with professional assessment, and to examine associated factors of importance for oral health, experiences, and mortality among older people in short-term care. Paper I describes oral health, daily oral care, and related factors among older people in short-term care and compares the older people’s self-perceived oral health with professional assessment of oral health.

4. 3. Thermal modelling and evaluation of borehole heat transfer

   Författare :Saqib Javed; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground source heat pump; fluid temperature; borehole; short-term; thermal response test; groundwater-filled; optimization; load aggregation; simulation; recovery; step-response; long-term; ground heat exchanger; times; design; ground-coupled;

   Sammanfattning : The use of ground source heat pump systems to provide heating and cooling inbuildings has increased greatly in the last decade or so. These systems have a highpotential for energy efficiency, which has environmental and economicadvantages. LÄS MER

5. 4. Genotoxic hazards in the rubber industry : application of short-term tests in work environment analyses

   Författare :Agneta Rannug; Stockholms universitet; []
   Nyckelord :;

   Sammanfattning : Excess mortality from a number of different types of cancer has been associated with work in the rubber industry. The aim of the present study - using short-term tests for mutagenicity - was to identify potentially hazardous additives and process fumes to which workers are exposed. LÄS MER

7. 5. Swallowing dysfunction among older people in short-term care : prevalence, effect of intervention, and risk of mortality

   Författare :Patricia Hägglund; Eva Levring Jäghagen; Per Wester; Mary Hägg; Karin Brunnegård; Per Östberg; Umeå universitet; []
   Nyckelord :swallowing disorder; dysphagia; elderly care; intermediate care; undernutrition; oral health; treatment; rehabilitation; quality of life; mortality risk; survival;

   Sammanfattning : Objectives: Swallowing dysfunction (dysphagia) is a common, but often neglected condition among geriatric patients that can cause severe complications such as malnutrition, aspiration pneumonia and death. The aims of this thesis were to (i) describe the study design and method of the multidisciplinary and multicenter project SOFIA (Swallowing function, Oral health, and Food Intake in old Age), (ii) study the prevalence of and the relationship between swallowing dysfunction and risk of undernutrition among older individuals in short-term care, (iii) study the effect of oral neuromuscular training on swallowing dysfunction among older individuals, and (iv) to investigate the association between poor oral health, swallowing dysfunction and mortality.
