TuFT: Tunnel Fire Tools - Teknisk dokumentation

Inom ramen för det svenska forskningsprojektet Taktik och metodik vid brand i undermarksanläggningar har ett enkelt planeringsverktyg utvecklats som bl a erbjuder stöd till beslutsfattare involverade i planeringen av räddningsinsatser i väg- och järnvägstunnlar. Verktyget, som har utvecklats vid Lunds universitet, heter TuFT och är en förkortning av Tunnel Fire Tools. TuFT kan beskrivas som ett myWithin the Swedish research project Rescue tactics and methodology during fires in underground facilities, a simple decision support tool has been developed. The tool can, for example, aid decision makers involved in the early phase of road and rail tunnel fire risk assessments. The tool has been developed at Lund University and has been termed TuFT, which is an abbreviation for Tunnel Fire Tools.

Animals and Humans : Reccurrent Symbiosis in Archaeology and Old Norse Religion

Animals have always been an important part of the human life-world, and they stand out as significant forces in the Old Norse mythology – here they became imaginary creatures with strong characters. The relationship between animals and humans in Scandinavia from Roman Iron Age to the Viking Period is explored in the book. Real animals and fantastical creatures in Midgard became mouthpieces for hu

On Modeling of Heat and Mass Transfer and other Transport Phenomena in Fuel Cells

Depending on specific configuration and design, a variety of physical phenomena is present in fuel cells, e.g., multi-component gas flow, energy and mass transfer of chemical species in composite domains and sites. These physical phenomena are strongly affected by chemical/electrochemical reactions in nano-/micro-scale structured electrodes and electrolytes. Due to the electrochemical reactions, g

The canonical equation of adaptive dynamics for life histories: from fitness-returns to selection gradients and Pontryagin's maximum principle.

This paper should be read as addendum to Dieckmann et al. (J Theor Biol 241:370-389, 2006) and Parvinen et al. (J Math Biol 67: 509-533, 2013). Our goal is, using little more than high-school calculus, to (1) exhibit the form of the canonical equation of adaptive dynamics for classical life history problems, where the examples in Dieckmann et al. (J Theor Biol 241:370-389, 2006) and Parvinen et al

Classroom acoustics and hearing ability as determinants for perceived social climate and intentions to stay at work.

Background noise and room acoustics may impede social interactions by interfering with oral communication and other cognitive processes. Accordingly, recent research in school environments has showed that social relationships with peers and teachers are described more negatively in rooms with long reverberation times (RT). The purpose of this study was to investigate how RT and hearing ability (i.

99mTc-Labeled Superparamagnetic Iron Oxide Nanoparticles for Multimodality SPECT/MRI of Sentinel Lymph Nodes.

The purpose of this study was to develop multimodality SPECT/MRI contrast agents for sentinel lymph node (SLN) mapping in vivo. METHODS: Nanoparticles with a solid iron oxide core and a polyethylene glycol coating were labeled with (99m)Tc. The labeling efficiency was determined with instant thin-layer chromatography and magnetic separation. The stability of the radiolabeled superparamagnetic iron

Actual diversity performance of a multiband diversity antenna with hand and head effects

Using the metric actual diversity gain (ADG), diversity performance is investigated for a compact mobile terminal prototype with two internal, triple frequency band antennas in four different cases of user interaction. ADG is presented as a preferred alternative to apparent diversity gain and effective diversity gain. Absorption due to user proximity causes degradation and imbalance in mean effect

Comparison of fertility and seasonal effects on grassland microbial communities

The activity of saprotrophic fungi and bacteria, and the balance between them, can affect decomposition. Arbuscular mycorrhizal (AM) fungi are also important for the nutrient and energy transfer in soil. Microbial community composition and activity are believed to have seasonal patterns, and are known to be highly influenced by environmental factors such as pH and nutrient conditions. To evaluate

Increased expression of the oxidative pentose phosphate pathway and gluconeogenesis in anaerobically growing xylose-utilizing Saccharomyces cerevisiae

Fermentation of xylose to ethanol has been achieved in S. cerevisiae by genetic engineering. Xylose utilization is however slow compared to glucose, and during anaerobic conditions addition of glucose has been necessary for cellular growth. In the current study, the xylose-utilizing strain TMB 3415 was employed to investigate differences between anaerobic utilization of glucose and xylose. This st

Discovery of a potent and long-acting bronchorelaxing capsazepinoid, RESPIR 4-95

BACKGROUND: Current drugs including beta-agonists have limited smooth muscle relaxant effects on human small airways. Yet this is a major site of obstruction in asthma and chronic obstructive pulmonary disease (COPD). OBJECTIVE: This study explores human small airway relaxant effects of RESPIR 4-95, a novel chemical analogue (capsazepinoid) to capsazepine. Capsazepine was recently shown to relax s

The ATLAS TRT electronics

The ATLAS inner detector consists of three sub-systems: the pixel detector spanning the radius range 4cm-20cm, the semiconductor tracker at radii from 30 to 52 cm, and the transition radiation tracker (TRT), tracking from 56 to 107 cm. The TRT provides a combination of continuous tracking with many projective measurements based on individual drift tubes (or straws) and of electron identification b

Towards the computational homogenization of discrete microstructures

The main objective of the current work is the extension of a computational homogenization scheme towards the simulation of discrete micro-structures. On the micro-level so-called multiple particle systems (MPS) are introduced for which a continuization scheme, resulting in a formulation analogous to a homogenization scheme, is developed . Furthermore, three types of constitutive behavior are appli
