Limited guidance is available to engineers on how people's walking speed in smoke can and should be represented in the fire safety design process of underground transportation systems, such as road and rail tunnels. To address this issue, the behaviour and movement of people in case of evacuation due to a fire in underground transportation systems has been investigated. In this paper, the relation
Mineral evolution is concerned with the timing of mineral occurrences, such as the earliest reported occurrences in the geologic record. Minerals containing essential Li have not been reported from rocks older than ca. 3000 Ma, thus the lithian tourmaline (fluor-elbaite) and mica (lepidolite) assemblage from a pegmatite near Zishineni associated with the ca. 3000 Ma Sinceni Pluton presents unusual
The registration of an observed point set to a known model to estimate its 3D pose is a common task for the autonomous manipulation of objects. Especially in industrial environments, robotic systems need to accurately estimate the pose of objects in order to successfully perform picking, placing or assembly tasks. However, the characteristics of industrial objects often cause difficulties for clas
Breast cancer is one of the most common cancers in women. It is most commonly treated by the surgical removal of the tumour in combination with (neo)-adjuvant therapy (hormone, chemo- or radio- therapy before or after surgery). However, a large number of patients are over treated, with approximately 60% being given adjuvant therapy when already cured by surgery alone. This causes many undesirable
Recent emission legislation in the marine sector has emphasized the need to reduce nitrogen oxides (NOx) emissions as well as sulphur emissions. The fulfilment of emission legislation limits with conventional marine diesel oil (MDO) requires complex and expensive aftertreatment systems and in this framework lean burn pilot ignited dual fuel (diesel and natural gas) is revealed as one of the most s
Biogas production from wheat straw is one strategy of converting biomass to bioenergy, but pretreatment of the lignocellulosic material is necessary in order to render the substrate biodegradable. In this study, four different mechanical pretreatments of wheat straw were investigated: roll milling, extrusion, pelletization, and hammer milling. The effects of the pretreatments on anaerobic digestio
Diverse organisms use Earth's magnetic field as a cue in orientation and navigation. Nevertheless, eliciting magnetic orientation responses reliably, either in laboratory or natural settings, is often difficult. Many species appear to preferentially exploit non-magnetic cues if they are available, suggesting that the magnetic sense often serves as a redundant or 'backup' source of information. Thi
Interest in learning in mature adulthood has become increasingly important as attention has been focused on what is seen to be an impending crisis in the near future, i.e., shortage of labour due to the ever-growing number of elderly and decreasing nativity rates. In some circles "alarmist demographics" have overshadowed an arguably more important concern, that of providing for aging individuals'
The Öresund Region, which encompasses a population of 3.5 million across Southern Sweden and Eastern Denmark, aims to be a regional ”powerhouse” in Europe for sustainability, innovation and clean-tech. It can therefore provide a ”laboratory” by which to experiment, implement, examine and evaluate the progress of (local) transition governance and infrastructural investments. The Urban Transition Ör
Popular Abstract in Swedish Det finns flera avancerade datormodeller att tillgå för att analysera och utvärdera brandsäkerheten i byggnader i samband med nyproduktion och ombyggnad. Denna typ av datormodeller kan, i många fall, göra bra förutsägelser av faktorer som är betydelsefulla för brandsäkerheten och därför är de viktiga verktyg vid brandtekniska analyser. Datormodellerna är dock komplexa o
Soft Magnetic Composites (SMC) based on iron powder have a strong potential for improving both the performance and the manufacturing of various electromagnetic components and devices, such as inductors, induction heaters and electrical machines. A new casting or moulding method we have developed makes use of a modified composite, termed SM2C, or soft magnetic mouldable composite. Use of it makes i
Protein interactions are important in understanding various protein relevant cellular and technological processes.This is a challenging task due to the intrinsically irregular shape and inhomogeneous surface distribution of neutral, charged, hydrophobic amino acid residues. This results inmore or less anisotropic interactions depending on external parameters such assalt and pH.

The pairing correlations of the nucleus 120Sn are calculated by solving the Nambu–Gor’kov equations, including medium polarization effects resulting from the interweaving of quasiparticles, spin and density vibrations, taking into account, within the framework of nuclear field theory (NFT), processes leading to self-energy and vertex corrections and to the induced pairing interaction. From these r
Peptide oligomerization dynamics affects peptide structure, activity, and pharmacodynamic properties. The thrombin C-terminal peptide, TCP-25 (GKYGFYTHVFRLKKWIQKVIDQFGE), is currently in preclinical development for improved wound healing and infection prevention. It exhibits turbidity when formulated at pH 7.4, particularly at concentrations of 0.3 mM or more. We used biochemical and biophysical a
Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr
The current research focuses in understanding how inlet pressure, EGR, combustion phasing, engine speed and pilot main ratio are affecting the main parameters of the combustion (e.g. efficiency, NOx, soot, maximum pressure rise rate) in the novel concept of injecting high octane number fuels in partially premixed combustion. The influence of the above mentioned parameters was studied by performing
Vehicle-to-vehicle (V2V) wireless communications can improve traffic safety at road intersections and enable congestion avoidance. However, detailed knowledge about the wireless propagation channel is needed for the development and realistic assessment of V2V communication systems. We present a novel geometry-based stochastic MIMO channel model with support for frequencies in the band of 5.2-6.2 G
This study investigates machining superalloy Inconel 718 with polycrystalline cubic boron nitride (pcBN) tooling both numerically and experimentally. Particular attention is given to mechanical and thermal stresses in the cutting tool arising from segmented chip formation and associated forces and temperatures. The temperature dependence of the mechanical properties of pcBN has been investigated a
