A Method to Introduce Building Performance Simulation to Beginners

Competence in performing Building Performance Simulations (BPS) is a fundamental asset for an energy specialist. However, teaching BPS to new students can be challenging, often due to the overwhelming capabilities of the software. The consequences for students are frustration and lack of confidence using the software, dividing group work based on previous expertise and, mostimportantly, the inabil

High antibiotic susceptibility among bacterial pathogens in Swedish ICUs

Local infection control measures, antibiotic consumption and patient demographics from 1999-2000 together with bacteriological analyses were investigated in 29 ICUs participating in the ICU-STRAMA programme. The median antibiotic consumption per ICU was 1147 (range 605-2143) daily doses per 1000 occupied bed d (DDD1000). Antibiotics to which >90% of isolates of an organism were susceptible were de

Så spred sig tobaken över världen.

Tobaksrökning är som tur är på nedåtgående i de flesta länder. Ändå är tobaksodlingen fortfarande en stor industri och många hoppas på att hitta nya användningsområden för denna giftiga växt. Lars Olof Björn och Ingvar Kärnefelt berättar tobakens historia ur ett både botaniskt och mänskligt perspektiv.

Turnover of 125I-labelled tissue kallikrein following intraduodenal or intravenous administration

UNLABELLED: Tissue kallikrein is released in the body both physiologically and in many inflammatory disorders. Little is, however, known about the turnover of released tissue kallikrein in humans. Approximately 1 mg of tissue kallikrein (mol wt 43,000 Da) was purified from 85 L human urine by: (1) ultracentrifugation, (2) filtration through an aprotinin-coupled Sepharose 4B column, followed by (3)

Spatial distribution of flying neodiprion sertifer (Hymenoptera, Diprionidae) males in a mature Pinus sylvestris stand as determined by pheromone trap catch

Field studies were conducted during three years to determine the vertical (height level) and horizontal (distance from stand edge) distribution of flying Neodiprion sertifer (Geoffroy) males in a non-outbreak population. Sticky traps baited with synthetic female pheromone (25, 35, 75-diprionyl acetate) were used in a mature stand of Scots pine (Pinus sylvestris L.) in Central Europe (southern Bohe

Sex pheromone of the pine sawfly Diprion pini (Hymenoptera : Diprionidae): Chemical identification, synthesis and biological activity

The main component of the sex pheromone secretion of female Diprion pini L. (Hymenoptera: Diprionidae) from insects collected both in Finland and in France has been identified as a threo-3,7-dimethyl-2-tridecanol (8 ng per female) stereoisomer by GC-MS and synthesis. The secretion also contains lower and higher homologues in small amounts (1-4% of the main component). Combined gas chromatographic-

Optimal Trade-Off between Economic Activity and Health during an Epidemic

This paper considers a simple model where a social planner can influence the spread-intensity of an infection wave, and, consequently, also the economic activity and population health, through a single parameter. Population health is assumed to only be negatively affected when the number of simultaneously infected exceeds health care capacity. The main finding is that if (i) the planner attaches a

Secondary Nucleation in Amyloid Formation

Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive. This thesis and the work herein is part of an ongoing effort to map out the aggre

TNFR1 is associated with short-term mortality in patients with diabetes and acute dyspnea seeking care at the emergency department

Background: Circulating levels of TNF alpha receptor 1 (TNFR1) and 2 (TNFR2) are associated with increased long-term mortality and impaired kidney function. Aim: To study association between circulating levels of TNFR1 and TNFR2 and short-term mortality in patients with diabetes and dyspnea. Population and methods: Patients aged ≥ 18 years seeking at emergency department (ED) during daytime on wee

Thermal conductivity of uterine tissue in vitro

Thermotherapy of the uterus has emerged as an alternative to hysterectomy in the treatment of menorrhagia, from whence it follows that the thermal properties of uterine tissue have become of importance. This study presents measurements of the thermal conductivity and the water content of uterine tissue in vitro. A steady-state thermal conductivity apparatus, based on the comparison of test samples

Electrical Characterisation of III-V Nanowire MOSFETs

The ever increasing demand for faster and more energy-efficient electricalcomputation and communication presents severe challenges for the semiconductor industry and particularly for the metal-oxidesemiconductorfield-effect transistor (MOSFET), which is the workhorse of modern electronics. III-V materials exhibit higher carrier mobilities than the most commonly used MOSFET material Si so that the

Food security in a changing climate : The role of cropland intensification and land acquisitions across Africa

Food security is one of the world’s greatest challenges. The current food system shows an entanglement across the globe which means that local farmers reliant on subsistence agriculture no longer operate in isolation of larger-scale processes within the global economy or the changing biophysical system of the planet. The persistently high number of undernourished people, volatile food prices, incr

The Not so Simple Stellar System ω Cen. II. Evidence in Support of a Merging Scenario

We present multiband photometry covering ∼5° × 5° across ω Cen collected with the Dark Energy Camera on the 4 m Blanco telescope, combined with Hubble Space Telescope and Wide Field Imager data for the central regions. The unprecedented photometric accuracy and field coverage allows us to confirm the different spatial distribution of blue and red main-sequence stars, and of red giant branch (RGB)
