Utrymningsvägars fysiska kapacitet. Sammanställning och utvärdering av kunskapsläget
An investigation has been made with the purpose to obtain information about evacuation capacity of various escape routes. Most of the data is although describing movement of people under normal conditions but some are coming from a test made to simulate fire and emergency situation. As a result of the investigation a number of diagrams are presented showing the walking speed and people flow in sta
Towards a learning organization: the introduction of a client-centered team-based organization in administrative surveying work.
Within administrative surveying work in Sweden, a transition to a client-centered team-based organization was made during 1998. The aim of this study was to describe the employees’ perceptions and expectations of job and organizational practices when working as a generalist in a client-centered team-based organization; job and organizational practices and well-being and effectiveness measures were
Gross nitrogen mineralization-, immobilization-, and nitrification rates as a function of soil C/N ratio and microbial activity
A laboratory experiment was designed to challenge the idea that the ON ratio of forest soils may control gross N immobilization, mineralization, and nitrification rates. Soils were collected from three deciduous forests sites varying in C/N ratio between 15 and 27. They were air-dried and rewetted to induce a burst of microbial activity. The N transformation rates were calculated from an isotope d

Direction of galvanically-induced vestibulo-postural responses during active and passive neck torsion
The direction of a postural response induced by galvanic vestibular stimulation depends on the head and trunk position. The relative importance of afferent information (proprioception) and efferent motor command/corollary discharge is unknown. We studied the direction of body sway evoked by galvanic vestibular stimulation in 9 healthy subjects during active and passive head positioning at 0 degree

Atrial fibrillatory rate and sinus rhythm maintenance in patients undergoing cardioversion of persistent atrial fibrillation.
The study set out to explore whether an index of atrial electrical electrophysiology can be used to predict atrial fibrillation (AF) relapse, and if the predictive properties differ as a result of arrhythmia duration. METHODS AND RESULTS: The study comprised 175 consecutive patients with persistent AF (median duration 94 days, range 2 to 1044) referred for cardioversion. Twenty-nine patients had a
Calculated optoelectronic properties of ruthenium tris-bipyridine dyes containing oligophenyleneethynylene rigid rod linkers in different chemical environments
Ruthenium tris-bipyridine dyes containing oligophenyleneethynylene (OPE) rigid rod linker groups ([Ru(bpy)(3)](2+), [Ru(bpy)(2)bpy-E-Ipa](2+), [Ru(bpy)(2)bpy-E-Ph-E-Ipa](2+), and [Ru(bpy)(2)bpy-E-Bco-E-Ipa](2+), where bpy = 2,2'-bipyridine, E = ethynylene, Ph = p-phenylene, Bco = bicyclo[2.2.2]octylene, and Ipa = isophthalic acid) have been investigated using DFT and TD-DFT calculations to elucida

Prospective, longitudinal quality-of-life study of patients with head and neck cancer: a feasibility study including the EORTC QLQ-C30
Despite modern advances in the treatment of head and neck cancer, the survival rate fails to improve. Considering the different treatment modalities involved, quality of life has been thought of as an additional end point criterion for use in clinical trials. A Nordic protocol to measure the quality of life of head and neck cancer patients before, during, and after treatment was established. Befor
Arbetssituation och stresshantering hos kabinpersonal
Allvarliga tillbud och olyckor inom flygtrafiken är relativt ovanligt, men när de inträffar ställs höga krav på kabinpersonalens förmåga att uppträda auktoritativt och effektivt. Det är dock inte bara vid ett direkt olyckstillbud det ställs stora krav på kabinpersonalens förmåga att hantera kritiska situationer. Det finns en hel flora av incidenter som kräver professionell hantering, t ex när passAlthough serious accidents or near-accidents are relatively rare in airline traffic, when they occur cabin attendants are expected to act effectively and with authority. However, the ability of cabin attendants to intervene professionally is also called for in other critical situations, such as when incidents that are frightening for the passengers occur or when passengers suddenly become ill. The
Efficient modelling necessitates standards for model documentation and exchange
In this paper, problems related to simulation model documentation and model exchange between users are discussed. Complex simulation models have gained popularity in the environmental field, but require extensive documentation to allow independent implementation. The existence of different simulation platforms puts high demands on the quality of the original documentation. Recent experiences from
Biomassebaserade energibärare för transportsektorn
Det finns en stor potential för ett ökat utnyttjande av biomassa för energiändamål i Sverige. En ökad användning av biomassa skulle kunna bidra till att minska utsläppen av koldioxid från förbränning av fossila bränslen, minska beroendet av importerade fossila energibärare samt påverka den regionala och lokala miljösituationen såväl positivt som negativt. Föreliggande studie behandlar framför alltThere is a large potential for increasing the use of biomass for energy purposes in Sweden. Increasing the use of biomass can reduce emissions of carbon dioxide (CO2) from fossil-fuel combustion and dependence on imported fossil fuels. Furthermore, increased biomass use will affect emissions of other air pollutants than carbon dioxide as well as environmental impacts from land use. The study deals
A human cell surface receptor activated by free fatty acids and thiazolidinedione drugs.
Fatty acids, which are essential nutritional components, are also involved in cardiovascular and metabolic diseases. Here we report a human cell surface receptor that we name free fatty acid receptor (FFAR), because it is specifically activated by medium to long-chain free fatty acids. The receptor belongs to the class of seven-transmembrane, G-protein coupled receptors (GPCRs) and also mediates r

Size-Resolved Respiratory Tract Deposition of Fine and Ultrafine Hydrophobic and Hygroscopic Aerosol Particles during Rest and Exercise
Airborne ultrafine particles (diameter <100 nm) are ubiquitous in the environment and have been associated with adverse health effects. The respiratory-tract deposition of these particles is fundamentally influenced by their hygroscopicity: their ability to grow by condensation of water in the humid respiratory system. Ambient particles are typically hygroscopic, to varying degrees. This article i
