Driving under the influence of prescription opioids: Self-reported prevalence and association with collision risk in a large Canadian jurisdiction.

Motor vehicle collisions are an important contributor to prescription opioid use-related morbidity and mortality. The purpose of the current study was to estimate the prevalence of driving under the influence of prescription opioids (DUIPO) in Ontario, Canada, and to measure the association between this behaviour and the risk of a motor vehicle collision.

Using horizontal curve speed reduction extracted from the naturalistic driving study to predict curve collision frequency.

Many models have been developed to predict collision frequency and evaluate safety performance on horizontal curves. The approach used in data collection or some assumptions made in the analysis methodology might lead to inaccurate results. For example, manual data collection, equipment limitations, and field experiments involving monitoring driving behavior for a specific region for a short-term are potential sources of errors in data collection. This paper aims at overcoming some of these issues in develo...


Efficacy of Cu(II) as an electron-shuttle mediator for improved bioelectricity generation and Cr(VI) reduction in microbial fuel cells.

Cu(II) ion was employed as an electron-shuttle mediator to enhance bioelectricity output and accelerate reduction rate of Cr(VI) in a dual-chamber microbial fuel cell (MFC). In the presence of Cu(II), power density and the Cr(VI) reduction rate were 1235.53 mW m and 1.191 g m h, respectively, which were 1.44 times and 1.17 times than that of MFC in the absence of Cu(II). A series of electrochemical analysis confirmed the presence of Cu(II) can diminish overpotential and diffusional resistance of M...

A qualitative exploration of driving stress and driving discourtesy.

Driving courtesy, and conversely driving discourtesy, recently has been of great interest in the public domain. In addition, there has been increasing recognition of the negative impact of stress upon the individual's health and wellbeing, with a plethora of interventions aimed at minimising stress more generally. The research literature regarding driving dis/courtesy, in comparison, is scant, with a handful of studies examining the dis/courteous driving behaviour of road users, and the relationship between...

Analysis of vehicle collision accidents based on qualitative mechanics.

In this paper, a method for vehicle collision analysis based on qualitative mechanics is presented. In collisions where accurate quantitative information is difficult to gather, this analytic method can act as a useful complement. Based on qualitative dynamic theories, reasonings of various factors including qualitative vector, collision behavior, translational and rotational motion are suggested. Using the law of momentum conservation within the frame of rigid-body dynamics, vehicle collision analyses base...

Internal radiation dose estimation using multiple D-shuttle dosimeters for positron emission tomography (PET): a validation study using NEMA body phantom.

Internal radiation dosimetry plays an important role in ensuring the safe use of positron emission tomography (PET) technology and is a legal requirement in most countries. We propose a new technique to estimate the internal radiation dose in PET studies by means of multiple D-shuttle dosimeters attached on the body surface of the patient.

Adaptive and dynamic RFID tag anti-collision based on secant iteration.

Radio frequency identification (RFID) has recently experienced unprecedented development. Among many other areas, it has been widely applied in blood station management, automatic supermarket checkout, and logistics. In the application of RFID for large-scale passive tags, tag collision is inevitable owing to the non-cooperation mechanism among tags. Therefore, a tag anti-collision method is a key factor affecting the identification efficiency. In this paper, we propose a tag anti-collision method based on ...

Bird-building collision risk: An assessment of the collision risk of birds with buildings by phylogeny and behavior using two citizen-science datasets.

Bird collisions with buildings are the second largest anthropogenic source of direct mortality for birds (365-988 million birds killed annually in the United States). Recent research suggests that this mortality occurs disproportionately across species. However, previous work had relied on regional and annual measures of relative species abundance. Our research identifies which species experience higher or lower collision rates than expected from local abundances using two sets of citizen science data: Minn...

To present the prevalence and concentrations of drugs in blood samples of drivers involved in road traffic accidents (RTA) and to discuss the effects of adopting different concentration cut-off values proposed or applied in other European countries on the number of driving under the influence of drugs (DUID) offences.

How does intersection field of view influence driving safety in an emergent situation?

Restricted intersection field of view (IFOV) can influence drivers' hazard detection abilities and driving safety in an emergent traffic event. However, no field studies or crash-data analyses have been conducted to prove the adequateness of the current intersection sight-distance design standards, which are adopted to ensure that the approaching-intersection drivers have a sufficient field of view to detect traffic hazards and travel safely at intersections. In this study, we conducted a driving simulator ...

Simulated car driving and its association with cognitive abilities in patients with schizophrenia.

Patients with schizophrenia commonly suffer from impairments in various aspects of cognition. These deficits were shown to have detrimental effects on daily life functioning and might also impair car driving. This study is the first to examine driving behaviour of patients with schizophrenia using an advanced driving simulator, and to explore the role of cognitive abilities of people with schizophrenia for driving.

Mechanistic alternatives for peptide bond formation on the ribosome.

The peptidyl transfer reaction on the large ribosomal subunit depends on the protonation state of the amine nucleophile and exhibits a large kinetic solvent isotope effect (KSIE ∼8). In contrast, the related peptidyl-tRNA hydrolysis reaction involved in termination shows a KSIE of ∼4 and a pH-rate profile indicative of base catalysis. It is, however, unclear why these reactions should proceed with different mechanisms, as the experimental data suggests. One explanation is that two competing mechanisms m...

Mass spectrometry is the science and technology of ions. As such, it is concerned with generating ions, measuring their properties, following their reactions, isolating them, and using them to build and transform materials. Instrumentation is an essential element of these activities, and analytical applications are one driving force. Work from the Aston Laboratories at Purdue University's Department of Chemistry is described here, with an emphasis on accelerated reactions of ions in solution and small-scale...

Cannabis smoking impairs driving performance on simulator and real driving: A randomized, double blind, placebo-controlled, crossover trial.

Driving experiments in real conditions are considered as a "gold standard" to evaluate the effects of drugs on driving performance. Several constraints are difficult to manage in these conditions, so driving simulation appears as the best alternative. A preliminary comparison is crucial before being able to use driving simulation as a valid evaluation method. The aim of this study was to design a driving simulation method for assessing drugs effects on driving. We used cannabis (THC) as a positive control a...
