This paper presents the results of an empirical study of wireless propagation channels for vehicle-to-vehicle communications in street intersections, a scenario especially important for collision avoidance applications. The results are derived from a channel measurement campaign performed at 5.6 GHz in four different types of urban intersections. We present results on typical power delay profiles,

BACKGROUND: Family members of persons with pre-dialysis chronic kidney disease may experience feelings of vulnerability and insecurity as the disease follows its course. Against this background, the aim of the present study was to explore empowerment in outpatient care as experienced by these family members. METHODS: An inductive approach for qualitative data analysis was chosen. The study sampl

Low-intensity laser prepulse ( < 10(13) W/cm(2), ns duration) are a major issue in experiments on laser-generation of protons, often limiting the performances of proton sources produced by high-intensity lasers (approximate to 10(19) W/cm(2), ps or fs duration) Several effects are associated to the prepulse and are discussed in this contribution: i) Destruction of thin foil targets by the shock ge

DNA-lipid interactions play a significant biological and biotechnological role but remain poorly understood. In investigations of mixed lipid-DNA systems a novel bicontinuous cubic phase, composed of lecithin, water and dodecyltrimethylammonium with DNA as the counterion (DNA-DTA), was identified. The cubic phase is stable only in a narrow composition range and in the temperature range 20-65 degre

The hydrogen sorption behavior of the Mg2FeH6-MgH2 hydride system is investigated via in-situ synchrotron and laboratory powder X-ray diffraction (SR-PXD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), particle size distribution (PSD) and volumetric techniques. The Mg2FeH6-MgH2 hydride system is obtained by mechanical milling in argon atmosphere followed by sintering

We present angle-resolved photoemission spectroscopy measurements of the surface states on in-situ grown (111) oriented films of Pb1-xSnxSe, a three-dimensional topological crystalline insulator. We observe surface states with Dirac-like dispersion at (Gamma) over bar and (M) over bar in the surface Brillouin zone, supporting recent theoretical predictions for this family of materials. We study th

MAPKs (mitogen-activated protein kinases) are signalling components highly conserved among eukaryotes. Their diverse biological functions include cellular differentiation and responses to different extracellular stress stimuli. Although some substrates of MAPKs have been identified in plants, no information is available about whether amino acids in the primary sequence other than proline-directed

This paper reviewed the application of membrane bioreactor in treating high strength industrial wastewater by analysing operational parameters, limitations and mitigations of MBR for industrial wastewater. High strength industrial wastewater is difficult to classify but by its characteristics can be predicted using biodegradability criteria (BOD5/COD). Several factors need to be taken into conside

The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project focuses on mountain building processes in a major mid-Palaeozoic orogen in western Scandinavia and its comparison with modern analogues. The project investigates the subduction-generated Seve Nape Complex. These in part under ultra-high-pressure conditions metamorphosed outer continental margin and continent

Abstract in Undetermined Aims: The aim was to characterize written narratives produced by a group of participants with aphasia. Methods & Procedures: Eight persons aged 28-63 years with aphasia took part in the study. They were compared with a reference group consisting of ten participants aged 21-30 years. All participants were asked to write a personal narrative titled 'I have never been so

Stricter Swedish building regulations require a moisture safety design process to be carried out before houses are built. In order to predict moisture-critical conditions, a properly verified, user-friendly and reliable calculation tool that could be used in this design phase, is required. This paper initially presents a blind method that could be used in order to verify hyg-rothermal calculation

Introduced species are interesting systems for the study of contemporary evolution in new environments because of their spatial and temporal scales. For this study we had three aims: (i) to determine how genetic diversity and genetic differentiation of introduced populations of the house sparrow (Passer domesticus) in Brazil varies with range expansion, (ii) to determine how genetic diversity and

Regulatory restrictions on antibiotic residues in dairy products have resulted in the illegal addition of beta-lactamase to lower antibiotic levels in milk in China. Here we demonstrate a fast, sensitive and convenient method based on enzyme thermistor (ET) for the surveillance of beta-lactamase in milk. A fixed amount of penicillin G, which is a specific substrate of beta-lactamase, was incubated

Frågan om brukarinflytande inom välfärdssektorn har sin grund i de krav på humanisering, demokratisering och maktdelning som höjdes av den ideella brukarrörelsen på 1960- och 70-talet. I dag har tanken om brukarinflytande anammats av det offentliga och de krav på inflytande som tidigare höjdes av en social rörelse utifrån och underifrån, drivs nu politiskt inifrån och uppifrån inom den offentliga The roots of the idea of user involvement within social services can be found in the efforts of the rising service user movement in the 1960s and 70s. Today the concept of “service user involvement” has been adopted by the state and is widespread within political rhetoric’s as well as in human service practices. However, user involvement is known to be an imprecise phenomenon that can take on diff

We present an efficient model for the simulation of polycrystalline materials, particularly accounting for the interactions of solid to solid phase-transformations and plasticity. The underlying one-dimensional model is embedded into amicro-sphere formulation in order to simulate three-dimensional boundary value problems. Representative numerical examples are provided for both the micro-level and

Background: Different foods can modulate cardiometabolic risk factors in persons already affected by metabolic alterations. The objective of this study was to assess, in healthy overweight individuals, the impact of a diet combining multiple functional concepts on risk markers associated with cardiometabolic diseases (CMD). Methods: Fourty-four healthy women and men (50-73 y.o, BMI 25-33, fasting

Mobile robots and robotic manipulators have traditionally been used separately performing different types of tasks. For example, industrial robots have typically been programmed to follow trajectories using position sensors. If combining the two types of robots and adding sensors new possibilities emerge. This enables new applications, but it also raises the question of how to combine the sensors
