This study evaluated long-term effects of 12 weeks of supervised training, of at least 45 minutes duration with two sessions per week, on physical performance and psychological well-being after myocardial infarction (MI). Sixty-nine patients were randomized to either an exercise or a nonexercise group. Maximum exercise capacity 6 weeks post-MI was inversely related to the acute peak aspartate amin

Objective: Adductor muscle strain in ice hockey is a major problem associated with reduced hip strength. The aims of this study were to examine between-limb differences in hip adduction and abduction strength, and adduction/abduction strength ratios in male elite junior ice hockey players. Further aim was to explore whether these hip strength measures are related to a history of groin injury. Meth

By aiming to establish single-ended standoff combustion diagnostics, bidirectional lasing emissions of atomic hydrogen at 656 nm wavelength have been generated via two-photon resonant excitation by focusing 205 nm femtosecond laser pulses into a premixed CH4/O2 flame. The forward lasing strength is approximately one order of magnitude stronger than that of the backward one, due to the geometry of

This article presents the results of a study of the Swedish multi-family housing stock in relation to its daylight performance under overcast sky conditions. A total of 8573 rooms in 35 existing buildings were investigated using advanced lighting simulations to determine their point daylight factor, as defined in the current building regulations. The buildings were selected based on their architec

This study assesses the trade-offs between the conflicting objectives of reducing heating intensity and increasing daylight utilization in the context of Swedish residential spaces, specifically for a north oriented bedroom. The optimization process is conducted within the visual programming environment of Grasshopper, where the simulation engines of Energyplus, Radiance and Daysim are interconnec

This is one the 13 chapters included in the book titled "Daylighting and Lighting under a Nordic sky". The chapter focuses on daylight simulation for buildings. It begins with the fundamental elements existing in every daylight simulation scenario, i.e. the scene geometry, the sky model, the ground, the areas of interest, the space usage and the simulation engine. The reader is introduced to diffe

We present the hard X-ray generation of K α lines in high-Z elements – platinum and tungsten – targets using the kHz repetition rate TW-class 850 nm, 10 fs laser pulses. The estimated Pt and W Kα1 X-ray photon flux from the recorded spectrum was 1.3 × 10 7 and 1.4 × 10 7 photons/s, respectively, in 2π solid angle. The calculated values of the photon conversion efficiency were 1.3 × 10 - 8 for

The activity of 158Tb was measured in waste samples from the Ignalina NPP Unit I RBMK-1500 reactor using gamma-ray spectrometry. The origin of 158Tb and the other observed gamma-ray emitters has been studied by using SCALE 6.1 modeling and comparing radionuclide ratios in the RBMK-1500 radioactive waste. The results of the calculation of the massic activity of gamma-ray emitters were used for inte

Depletion of RBMK-1500 spent nuclear fuel (SNF) with and without an erbium burnable absorber was modelled, and onegroup burn-up dependent cross-section libraries for Origen-ARP were created. Depletion calculations for the generation of crosssection libraries were performed using the SCALE 6.1 code package with the TRITON control module, which employs the NEWT deterministic 2D transport code with t

The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot. PPC emerged from the knowledge gained from homogeneous charge compression ignition (HCCI) research. To extend the load range and thus reduce cylinder pressure rise rates, the fuel is directly injected during the comThe concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot.

The purpose of this work is to indicate the actinides input to the total radiation dose caused by the irradiated graphite of the RBMK-1500 reactor in comparison to the dose delivered by other nuclides. We used computer codes (SCALE 6.1 and MCNPX 2.7) to estimate the dose rate delivered by actinides giving special attention to the 244 Cm isotope as a critical contributor to the total activity of

Safe long-term storage of spent nuclear fuel (SNF) is one of the main issues in the field of nuclear safety. Burn-up credit application in criticality analysis of SNF reduces conservatism of usually used fresh fuel assumption and implies a positive economic impact for the SNF storage. Criticality calculations of spent nuclear fuel in the CONSTOR® RBMK-1500/M2 cask were performed using pre-generat

The activation of graphite in the nuclear power plants is the problem of high importance related with later graphite reprocessing or disposal. The activation of actinide impurities in graphite due to their toxicity determines a particular long term risk to waste management. In this work the activation of actinides in the graphite constructions of the RBMK-1500 reactor is determined by nuclear spec

This project consists of a thorough study of an energy efficient and moisture safe row-house, located in the Nordic climate of Sweden. Climate and site analysis, building scale design decisions and finally the evaluation and optimization of its energy performance were different steps of a holistic process aiming at the architectural quality, energy efficiency, comfort and the well-being of users.

The importance of daylight to occupants’ health and wellbeing has been extensively documented, as well as its role in reducing electric lighting use. As a result, most countries have today some form of regulatory framework, specifying minimum daylight requirements for built spaces. The present Swedish building code (BBR – BFS 2011:6) includes general recommendations for daylight provision of resid

Poststroke recovery requires multiple repair mechanisms, including vascular remodeling and blood-brain barrier (BBB) restoration. Brain pericytes are essential for BBB repair and angiogenesis after stroke, but they also give rise to scar-forming platelet-derived growth factor receptor β (PDGFR-β)–expressing cells. However, many of the molecular mechanisms underlying this pericyte response after st

One of the most important production processes in industry is metal cutting. If a product is not a machined metal part, it is likely that the mould, die and tools used to produce the product or parts of the product are machined. The tools, machines and time spent add to the cost of the finished product and both industry and academia spend considerable effort in increasing efficacy and minimizing t
