The short- and long-term effects of heavy-resistance training (85% of one-repetition maximum (RM)) on elbow flexion and knee extension dynamic and isokinetic strength and on morphology in the biceps brachii and vastus lateralis muscles were evaluated during 1 year in 35 Scandinavian men and women, aged 70-77 years, 12 of whom formed a control group. After the first 11 weeks of training (n = 23; 3

The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. The moisture in the paper is controlled by adjusting the set point of the steam pressure controllers. There exist several commer

This paper analyzes MIMO propagation channels for personal area networks. Such channels show important differences to propagation channels in wide-area networks, due to the different environments in which the systems are operated, as well as due to different mobility models, ranges, and presence of humans in the environment, and the impact of the antenna arrangement. We present results from a rece

Self-organization and pattern formation represent the emergence of order in temporal and spatial processes. Self-organization in population ecology is gaining attention due to the recent advances concerning temporal fluctuations in the population size of dispersal-linked subunits. We shall report that spatially structured models of population renewal promote the emergence of a complex power law or

Objective. Helicobacter pylori infection is an established risk factor for non-cardia gastric adenocarcinoma. Infection with H. pylori strains harbouring the cagA pathology island may augment this association. H. pylori infection may at the same time reduce the risk for oesophageal carcinoma. However, prospective data on the association between CagA seropositivity and gastric or oesophageal carcin

The ground volume is penetrated by a duct system for injection and extraction of heat. The heat transfer properties between the ground and such a system is here characterized by a heat transfer length. The heat exchange between the soil and the ducts is represented by a heat source/sink distribution in the storage region.

Absolute regional cerebral blood flow (CBF) was measured in ten healthy volunteers, using both dynamic susceptibility-contrast (DSC) magnetic resonance imaging (MRI) and Xe-133 SPECT within 4 h. After i.v. injection of Gd-DTPA-BMA (0.3 mmol/kg b.w.), the bolus was monitored with a Simultaneous Dual FLASH pulse sequence (1.5 s/image), providing one slice through brain tissue and a second slice thro

Physicochemical changes of dietary fibre in the presence of NaCl or CaCl2 (0, 100 or 400 mM) during boiling (4 or 25 min) of blanched/frozen carrots were investigated, Addition of NaCl (100 mM) to the boiling water reduced total dietary fibre (TDF) content, due to a reduction of insoluble polymers. Higher concentrations had no further effects. NaCl showed minor effects, on molecular weight distrib

A study of effects induced in the Be is core level spectrum and in the surface band structure after Si adsorption on Be(0001) is reported. The changes in the Be is spectrum are quite dramatic. The number of resolvable surface components and the magnitude of the shifts do decrease and the relative intensities of the shifted components are drastically different compared to the clean surface. The sur

DNA aneuploidy, which reflects changes in nuclear DNA-content, as determined cytometrically is a candidate prognostic factor in squamous cell carcinoma of the head and neck. The aim of this study was to compare two different preparation methods with respect to their use in detecting aneuploid tumor cell populations in malignant tumors of the head and neck. Fresh frozen tumor material was used. The

First International Symposium on Problems with cold work at Grand Hotel Saltsjöbaden, Stockholm, Sweden on November 16-20, 1997. Organised by, National Institute for Working Life, Solna, Sweden in co-operation with National Institute of Occupational Safety and Health, Cincinnati, USA; National Institute of Occupational Health, Moscow, Russia; National Institute of Public Health, Tokyo, Japan, unde

The aim of the present study was to model apparent serum half-lives of polybrominated diphenyl ethers (PBDEs) with 7-10 bromine substituents. Workers with occupational exposure to PBDEs have elevated serum levels of PBDEs, but these substances are also found in the general population and are ubiquitous environmental contaminants. The calculations were based on exposure assessments of rubber worker

This report is the thesis of the research and development project entitled: Development of a Resource Saving Concept for the Establishment of a Climate Suitable for the Storage of Objects Worthy of Preservation in Storerooms at Museums and in Archives. In short: The ZEPHYR project. This work is the result of a research and development project. The aim is to improve the possibilities of using pass

A simulation of the n -> pi* absorption and the pi -> n fluorescence of acetone in aqueous solution is reported. The model has an explicit solvent representation with an effective ab initio treatment of the solute. The model attempts to balance quantum chemistry, intermolecular interactions and statistical thermodynamics. It includes a non-electrostatic perturbation on the solute which models the

A sensitivity study was performed with a nonlinear elastic finite element model for monotonic analyses of wood-framed shear walls. The objective was to provide information about simplifying a model of wood-framed shear walls with no significant loss in accuracy. The simplifications concern features such as slips in joints between frame members, slips in hold-down connections, and bearing between a
