PurposeThe purpose of this study is to increase the understanding of multiple stakeholders’ needs, benefits and challenges, with a focus on information sharing, to improve efficiency and safety in the transportation of dangerous goods by road, rail, and sea.Design/methodology/approachInspired by grounded theory, this study is based on 21 semi-structured interviews with stakeholders representing au
A new product, the surface emissions trap (cTrap), a device developed to stop and bind emissions effectively while having virtually no resistance to water vapor, was installed on a PVC flooring in a school with IAQ complaints. After the installation air concentrations of 2-ethylhexanol decreased rapidly and staff and students reported a considerably improved perceived IAQ. The amounts of 2-ethylhe
In many European countries, it is a political goal that future growth in local travel should be absorbed by sustainable transport modes. Concerns that increased walking and cycling produce more accidents have been countered by the "safety in numbers" (SiN) argument. According to SiN, the more walkers/cyclists there are in a population, the lower their risk. SiN has been demonstrated in cross secti
Simple models are less input demanding and their calibration involves a lower number of parameters, however their general applicability to vast areas must be tested. We analysed if a simple ecosystem model (PRELES) can be applied to estimate carbon and water fluxes of Boreal forests at regional scale. Multi-site (M-S) and site-specific (S-S) calibrations were compared using evapotranspiration (ET)
Modern society is becoming increasingly dependent on a continuous supply of electricity. In order to maintain the safety and security of society and its citizens, it is therefore necessary that electricity networks are resilient toward disruptions whether caused by natural disasters, sinister attacks, or other. Margin and sensitivity are two crucial aspects of the resilience concept which have so
Purpose: Individuals with tetraplegia depend on alternative interfaces in order to control computers and other electronic equipment. Current interfaces are often limited in the number of available control commands, and may compromise the social identity of an individual due to their undesirable appearance. The purpose of this study was to implement an alternative computer interface, which was full
This article identifies factors which contribute to households’ willingness to pay for improving and protecting a multiple-use water scheme in Ethiopia. It does so through descriptive statistics, a probit model and contingent valuation methods complemented with qualitative data. Estimates suggest farmers’ willingness to pay is based on gender, the prevalence of waterborne disease, the time to coll
A major obstacle in ex vivo gene transfer has been the loss of transgene expression soon after implantation of the grafted transduced cells. Recently, a lentiviral vector system has been developed which has proven to express high levels of transgenes in vivo after direct injection into the tissue. In this study, we have investigated the use of such a vector for ex vivo gene transfer to the brain.
Among the issues relating to the needs of citizens with reduced functional capacity, accessibility problems throughout society are gaining interest. The focus of this paper is on methodology for assessment of urban public bus transport accessibility. The aims are to describe the development of a pilot version of a new instrument, the Travel Chain Enabler, and to identify problems to target for fur
Human pluripotent stem cells provide new choices for sources of A9-type dopaminergic (DA) neurons in clinical trials of neural transplantation for patients with Parkinson's disease (PD). For example, "self" and HLA-matched A9 DA neurons may improve the patient-to-patient variability observed in previous clinical trials using fetal DA neurons and obviate the need for long-term immunosuppression in
The implementation of global anti-doping regulations was intended to provide a level playing field for all athletes entering sports competitions. However, studies have shown that the worldwide harmonization of rules has not been entirely efficacious. For instance, great variation has been found in how anti-doping organizations implement anti-doping regulations, and it has also been shown that athl
PURPOSE: To investigate whether TT virus (TTV) viral load may be used as a surrogate marker for functional immune reconstitution in HIV-infected patients receiving highly active antiretroviral therapy (HAART).METHOD: Fifteen protease inhibitor-naïve HIV-infected patients were included in a longitudinal study. From each patient, three serum samples taken before HAART initiation and three samples ta
This paper presents a novel approach for the elaboration of an integration strategy for controls and computing systems at large particle accelerator based research facilities. The approach is applied in a specific case study conducted at the world-leading neutron science facility European Spallation Source (ESS). First, an introduction to the term 'integration' in the Systems Engineering literatur
We present the PalCom Object Notation, a textual data representation format for communication between internet of things which support binary and textual data. The format does not require parsing of user data (or the “payload”) and is thus efficient to use also for large binary values such as digital images, audio and video as well as for short textual values. These can be mixed in the same messag
The electric and magnetic polarizabilities of the proton are now well known, owing to Compton scattering measurements on hydrogen targets; however, the neutron polarizabilities are still relatively uncertain, compared to the proton values. To address this problem, a multiinstitutional collaboration has conducted a program of elastic Compton scattering experiments on deuterium at the MAX IV Laborat
In this paper, we propose a class of Generalized Gough-Stewart Platforms (GGSPs) used, as a novel approach, to eliminate the classical isotropic constraint of GSPs (hexapods). GGSPs are based on the standard GSP architecture with additional rotations of the three strut-pairs. Despite the architectural generalization introduced in GGSPs, they do not require much more effort in order to be fabricate
Background and Aims: Small-bowel bleeding is the primary indication for capsule endoscopy (CE). Many experts advocate a "watch-and-wait" policy in negative CE. This meta-analysis examines the odds of rebleeding after negative index CE and the impact on long-term follow-up. Methods: A comprehensive literature search identified articles examining the rebleeding rate after negative CE. Demographic an
Introduction: In Italy the course to become a general practitioner (GP) lasts 3 years and includes both theoretical and practical study. Different from the theoretical part, until recently the practical activity has not been assessed at all. The Emilia Romagna Regional Health Authority has developed a special program called INFORMEG (Management of Tutoring during the Triennial Specific Training in
