Differences in the risk profiles of drunk and drug drivers: Evidence from a mandatory roadside survey

Background: The study assesses the prevalence rates of alcohol- and drug-involved driving in Catalonia (Spain). Method: Drivers were randomly selected for roadside testing using a stratified random sampling procedure representative of all vehicles circulating on non-urban roads. Mandatory alcohol and drug tests were performed during autumn 2017. A sample of 6860 drivers were tested for alcohol use, of these 671 were also tested for drugs. Standard procedures were employed by traffic officers to detect alcohol and drug use. Alcohol breath tests were performed with breathalyser devices and on-site drug screening systems were used to test for drugs. Results: The prevalence of alcohol use above the legal limit and drug use were 1.2 % (95 % CI: 0.9-1.5 %) and 8.3 % (95 % CI: 5.8-11.2 %), respectively. The most frequent drugs detected were THC (5.6 %, 95 % CI: 3.7-8.0 %), cocaine (3.5 %, 95 % CI: 2.0-5.5 %) and amphetamines (1.6 %, 95 % CI: 0.6-3.4 %). Alcohol use was detected more frequently on conventional roads, at weekends and during night-time hours. Drug use was detected more frequently in young males during daytime hours. Conclusions: Driver risk profiles associated with alcohol use and drug use differ. Positive alcohol use is not a predictor of drug use when controlling for all other factors.

Elevated Lithium Ion Regulation by a Natural Silk Modified Separator for High-Performance Lithium Metal Anode

Metallic lithium anode has long stood as the holy grail in the field of secondary batteries for its high theoretical specific capacity and low electrochemical potential. But its edge is blunted by the inherent uncontrolled lithium dendrite growth that can curtail the cycle life and raise safety concerns. In this work, a functional modification layer from a derivant of natural silk is developed to protect lithium anode via a facile automatic transfer route. Via offering abundant functional group sites, the Li-ion flux on the anode surface is made uniform efficiently. The silk fibroin-based modification layer also contributes to the in situ formation of a Li3N-rich solid electrolyte interphase film on the lithium anode. Consequently, a high-performance lithium metal anode with dendrite-free morphology and significantly enhanced cycle stability is achieved: when paired with LiFePO4 cathodes, the full cell achieves a long-term cycling stability of 3000 cycles at 5 C; when paired with sulfur cathodes (5 mg(sulfur) cm(-2)), a long lifespan for over 400 cycles at 1 C is achieved. This work offers a facile and practical approach for the interface modification of the high-performance lithium anode and as well as provides a new perspective for the application of biomass-based materials in advanced batteries.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 870-72-4. Name: Hydroxymethanesulfonic Acid Sodium Salt.

Skull Fracture Patterns and Morphologies Among Fatal Motorcycle Traffic Accident Victims in Vietnam

We aim to describe morphological structures of skull fractures and relevant factors in motorcycle accident victims in Vietnam. This work represents a retrospective cross-sectional study based on forensic reports of fatal motorcycle accident victims. Between January 2013 and August 2019, a total of 226 fatal motorcycle accident patients with skull fracture diagnoses were enrolled. Linear and depressed fractures were the common patterns (46.0% and 37.2% of cases, respectively), whereas stellate (11.5%) fractures were rare. Fractures of the temporal bone (68.6% of cases) and basilar skull (60.6%) were the most common, whereas fractures of the parietal bone were the least common (9.7%). Two or more patterns of skull fracture were recorded in 25.5% of cases, and 2 or more fracture locations were recorded in 76.6% of cases. Fractures of the parietal bone were associated with victims not wearing a helmet. In addition, fractures of the basilar skull were more likely to occur among victims with alcohol consumption. We found the common pattern of skull fractures was linear and depressed fractures, and the common location of skull fractures was temporal and basilar bone. Further studies that include larger sample sizes and collect more information should be conducted to better understand relationships between skull fractures and related factors.

Girdling stimulates anthocyanin accumulation and promotes sugar, organic acid, amino acid level and antioxidant activity in red plum: An overview of skin and pulp metabolomics

Girdling is a widespread agronomic technique to increase the fruit quality characteristics (e.g. size, solid soluble content [SSC] and colour). However, the information on the fruit metabolic changes related to this practice still remains unclear and fragmentary. Moreover, girdling duration and application time may greatly affect the plant/ fruit metabolic responses producing sometimes counterproductive results. Fruit quality, metabolomic and antioxidant analyses were conducted to characterise the effects of two different girdling dates (4- and 2-weeks before the harvest, 4 W and 2 W, respectively) in skin and pulp of red-fleshed plum (Prunus cerasifera var. pissardii). Overall, the pulp metabolism was altered in both 4 W and 2 W Girdling by inducing accumulation of sugars (sucrose and trehalose), sugar alcohols (inositol and xylitol), organic acids (especially some TCA cycle intermediates such as alpha-ketoglutaric, citric, isocitric, fumaric and malic acid), amino acids (beta-alanine and L-proline), anthocyanins and other phenols. In the skin only girdling 4 W showed major significant differences compared to the control increasing the fruit quality characteristics (size, SSC, dry matter and red colour) and showing greater metabolic changes with respect to the controls. Furthermore, the total antioxidant activity was also increased in both skin and pulp respect to other treatment only in Girdling 4 W. This approach could be used with both P. cerasifera plums as well as other red-fleshed fruit species in order to ensure red-fleshed fruits production with a uniform red colouration and higher content of bioactive compounds.

Modified Drinking Motives Questionnaire-Revised: Psychometric Validation in a Psychiatric Sample of Young Adults with Predominantly Polysubstance Use

Introduction: Measures of motives for alcohol use provide an important avenue for understanding underlying psychological reasons that drive substance use and predict distinct patterns of use. The Modified Drinking Motives Questionnaire-Revised (MDMQ-R; Grant, Stewart, O’Connor, Blackwell, Conrod, 2007) measures five drinking motives: social, enhancement, conformity, coping-with-anxiety, and coping-with-depression. The MDMQ-R and its predecessors have previously been validated only in non-clinical normative samples. Purpose: Therefore, the present study aimed to validate the factor structure and internal consistency of the MDMQ-R in a diverse psychiatric sample of substance-using young adults that presented with either exclusive alcohol use or polysubstance use. Method: Participants were 255 substance-using young adults (18-26 years; M = 21.17) admitted to the young adult partial hospitalization treatment program at a private psychiatric hospital (62% female; 78% White; 43% students). Results: A confirmatory factor analysis revealed that items loaded on their respective latent factors (ps < 0.01; loadings between 0.50 and 0.90; reliabilities between 0.80 and 0.94). However, goodness of fit statistics were not reflective of model fit found in Grant et al. (2007) in the overall sample, as well as in alcohol-only and polysubstance-using samples. Discussion: Results suggest that the factor structure of the MDMQ-R did not replicate in the present sample. Potential explanations and future directions are discussed in light of the results, including generalizability and clinical utility.

Some studies on the mutual diffusion, Joule-Thomson inversion curve and virial coefficients of binary mixtures containing diethylamine and (C-5 – C-9) 1-alkanol

In this study, second and third virial coefficients and the Joule-Thomson inversion curves for the binary mixtures of diethylamine (DEA) with 1-pentanol up to 1-nonanol were calculated regarding the Peng-Robinson-Stryjek-Vera (PRSV) equation. Experimental densities were used to calculate the adjustable parameters of the PRSV equation. The estimation of the thermodynamic factor for the binary systems from the COSMO-RS model shows that the considered mixtures exhibit a negative deviation from Raoult’s Law. Besides, the diffusion coefficients for the binary mixtures in the whole composition range were determined regarding experimental viscosities. The results were analyzed to gain information about the liquid structure in the binary mixtures. It has been shown that intermolecular forces between DEA and 1-alkanol, which changes with the alcohol chain length, have a significant impact on the above-mentioned parameters. The investigation has shown that increasing the alcohol chain length reinforces the strength of intermolecular interactions. (C) 2020 Elsevier B.V. All rights reserved.

Comparative Transcriptome Analysis of Hybrid Population Provides Insights Into Starch Content in Sweet Potato (Ipomoea batatas L.) Storage Root

Sweet potato is an important starchy crop, which is mainly utilized as food, animal feed, and fermented to produce fuel-grade alcohol. However, the genetic mechanism regulating starch content in sweet potato is not yet fully understood. In this study, transcriptome analysis was performed in sweet potato cultivars Luoxushu 8 (high starch), Zhengshu 20 (low starch), and 12 hybrid F-1 lines (six high-starch lines and six low-starch lines), which detected a total of 85,493 genes. The high and low-starch content groups were compared and found that 47 and 64 genes were up-regulated and down-regulated, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that seven differentially expressed genes were significantly enriched in the ATP-binding cassette (ABC) transporter pathway. Among them, five genes (annotated as ABCB1) that might involve in the auxin transport were significantly down-regulated in high-starch group. Meanwhile, the storage root sizes of Zhengshu 20 were higher as compared with Luoxushu 8. Simultaneously, four of the five differentially expressed genes enriched in the starch and sucrose metabolism pathway were up-regulated in high-starch group. These results provided the basis for the study of starch content in sweet potato storage root.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 105-13-5, in my other articles.

Effect of multiscale reinforcement by fiber surface treatment with polyvinyl alcohol/graphene oxide/oxidized carbon nanotubes on the mechanical properties of reinforced hybrid fiber composites

Polyvinyl alcohol-graphene oxide-oxidized carbon nanotube (PVA-GO-OCNT) hybrid coatings were adopted to modify glass fibers (GFs) and carbon fibers (CFs), and modified GF/CF-reinforced polyurethane hybrid composites (PVA-GO-OCNTs-HFs/PUs) with different concentric hybrid structures were prepared. The synergistic effect of the hybrid structure and surface modification of hybrid fibers (HFs) on the mechanical properties of hybrid composites was investigated systematically. The results show that the hybrid structure can optimize the comprehensive mechanical properties of HF-reinforced composites (HFRCs) by combining the performance advantages of the two types of fiber reinforcement, and the strength of the interface between HFs and polyurethane (PU) plays a crucial role in whether the advantages of the hybrid structure can be fully achieved. In addition, the mechanical properties of the composite were significantly enhanced, and the structural advantages of the hybrid structure were further improved after HFs were modified by PVA-GO-OCNT hybrid coating. The hybrid effect on the tensile strength of HFRCs with CF as the core and GF as the shell changes from a negative hybrid effect (5.4%) before modification to a positive hybrid effect (4.3%). The hybrid effect in tensile failure strain of HFRCs with GF as the core and CF as the shell changes from a negative hybrid effect (2.1%) before modification to a positive hybrid effect (2.1%). Moreover, the interlaminar shear strength of HFRCs modified by PVA-GO-OCNT hybrid coating is significantly higher than that of unmodified HFRCs.

Divergent, Strain-Release Reactions of Azabicyclo[1.1.0]butyl Carbinols: Semipinacol or Spiroepoxy Azetidine Formation

The azetidine moiety is a privileged motif in medicinal chemistry and new methods that access them efficiently are highly sought after. Towards this goal, we have found that azabicyclo[1.1.0]butyl carbinols, readily obtained from the highly strained azabicyclo[1.1.0]butane (ABB), can undergo divergent strain-release reactions upon N-activation. Treatment with trifluoroacetic anhydride or triflic anhydride triggered a semipinacol rearrangement to give keto 1,3,3-substituted azetidines. More than 20 examples were explored, enabling us to evaluate selectivity and the migratory aptitude of different groups. Alternatively, treatment of the same alcohols with benzyl chloroformate in the presence of NaI led to iodohydrin intermediates which gave spiroepoxy azetidines upon treatment with base. The electronic nature of the activating agent dictates which pathway operates.

Fire hazard prevention and protection in neurosurgical operating rooms revisited: A literature review challenged by a recent incident report

We present the case of an 11 month old boy with history of sagittal synostosis who underwent a cranial vault reconstruction for repair. During the case, surgical irrigation spilled onto the plug in the operating room table, resulting in sparks and a small fire. The fire was contained and extinguished. The patient suffered no injury. We discuss previous cases of fires in neurosurgical operating rooms and identify a new source of ignition for fires. We also explore recommended best practices for fire prevention and safety to identify ways to prevent instances like this from occurring in the future.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 111-41-1. COA of Formula: C4H12N2O.
