Enhanced anticorrosion properties of nitrogen ions modified polyvinyl alcohol/Mg-Ag ions co-incorporated calcium phosphate coatings

Nitrogen ions (70 keV) were implanted on composite coatings containing polymer/Mg (magnesium)-Ag (silver) ions co-incorporated hydroxyapatite which was developed using microwave irradiation. Average crystallite size of modified coatings is reduced by 80% compared to the pristine. The variation of atomic bond strength of modified coatings is realized. The electrical resistance (77%), microhardness (4.3%), roughness (4.5 times) and pore size are enhanced on the nitrogen implanted coatings. Superhydrophilic surface is turned to hydrophobic on implantation. At higher fluence (1 x 10(17) ions/cm(2)) depicted an enhanced corrosion potential compared to the other coatings. Thus, the new insight on modified coatings is elucidated by correlating phase-structure, surface and corrosion resistance.

Cannabis use disorder and post-traumatic stress disorder: The prevalence of comorbidity in veterans of recent conflicts

Aims: Veterans have high rates of cannabis use, and rates of cannabis use disorder (CUD) are rising among this population. These rising rates are particularly true for veterans with post-traumatic stress disorder (PTSD), which is common among veterans of recent conflicts, Operations Enduring Freedom, Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND). Although prior work has documented links between PTSD and cannabis use, a better understanding of the intersection among CUD, PTSD, and other disorders in real-world clinical practice can inform prevention and treatment efforts. This study examined the prevalence and comorbidities of CUD and PTSD in OFE/OIF/OND veterans. Method: The study analyzed data from the Veterans Affairs Corporate Data Warehouse (2010-2016) for returning war veterans who were diagnosed with CUD (N = 46,268). The study determined prevalence of PTSD, and examined additional differences in comorbidities. Results: The prevalence of a comorbid PTSD diagnosis among OEF/OIF/OND veterans with a CUD diagnosis was 72.3%. Further analysis revealed additional co-occurring disorders. Veterans with a diagnosis of CUD and PTSD were more likely to have a comorbid diagnosis of depression (odds ratio, 1.69; 95% CI, 1.62-1.71), panic disorder (odds ratio; 1.58; 95% CI, 1.43-1.75), alcohol use disorder (odds ratio; 1.30; 95% CI, 1.24-1.35), opioid use disorder (odds ratio; 1.52; 95% CI, 1.43-1.62), and insomnia (odds ratio; 1.74; 95% CI, 1.65-1.84) than veterans without a PTSD diagnosis. Conclusions: Findings highlight that the majority of returning war veterans with CUD are highly complex. Our findings substantiate the need for urgent, comprehensive care for veterans with co-occurring CUD and PTSD, including integrated and transdiagnostic treatment approaches.

Differential Microwave Resonator Sensor for Real-Time Monitoring of Volatile Organic Compounds

In this work, a noninvasive microwave gas sensor suitable for accurate and real-time tracking of volatile organic compounds concentration is presented. The proposed differential sensor was comprised of two independent split-ring resonators in power splitter/combiner configuration to enhance the robustness of the sensor to changes in environmental parameters. The designwas fabricatedon a Rogers RT/duroid 5880 high-frequency substrate and operated at f(s) = 5.12 GHz and f(r) = 5.65 GHz, referring to the sensing and reference resonant frequencies, respectively. A thin layer of polydimethylsiloxane was used as an interface layer in the sensing resonator region with the strongest electric field to enable gas sensing with high sensitivity. The performance of the sensor was validated by introducing different volatile organic compounds, such as acetone, methanol, ethanol, and isopropyl alcohol. Time-based responses of the sensor demonstrated the capability of the sensor to monitor different concentrations of acetone vapor ranging from low, 387 to 1935 ppm, with the sensitivity of 0.02 mdB/ppm and high concentrations, 3878 to 62048 ppm, with sensitivity of 0.0125 mdB/ppm.

Fe-Catalyzed Anaerobic Mukaiyama-Type Hydration of Alkenes using Nitroarenes

Hydration of alkenes using first row transition metals (Fe, Co, Mn) under oxygen atmosphere (Mukaiyama-type hydration) is highly practical for alkene functionalization in complex synthesis. Different hydration protocols have been developed, however, control of the stereoselectivity remains a challenge. Herein, highly diastereoselective Fe-catalyzed anaerobic Markovnikov-selective hydration of alkenes using nitroarenes as oxygenation reagents is reported. The nitro moiety is not well explored in radical chemistry and nitroarenes are known to suppress free radical processes. Our findings show the potential of cheap nitroarenes as oxygen donors in radical transformations. Secondary and tertiary alcohols were prepared with excellent Markovnikov-selectivity. The method features large functional group tolerance and is also applicable for late-stage chemical functionalization. The anaerobic protocol outperforms existing hydration methodology in terms of reaction efficiency and selectivity.

Prevalence and determinants of chronic kidney disease in urban adults’ populations of northern Cameroon

Background Chronic kidney disease (CKD) is a major health problem with growing prevalence in sub-Saharan Africa. Aim Assess the prevalence and determinants of CKD in Garoua and Figuil cities of the North region of Cameroon. Methods A cross-sectional survey was conducted from January to June 2018 in the two cities, using a multi-level cluster sampling. All adults with low estimated glomerular filtration rate (eGFR) (< 60 ml/min/1.73 m(2)) by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation and/or albuminuria (>= 30 mg/g) were reviewed three months later. Logistic regression models (accounting for the sampling strategy) were used to investigate the predictors of the outcomes. Results A total of 433 participants were included, with a mean age (95%CI) of 45.0 (43.4-46.6) years, 212 (48.7%) men, 294 (67.9%) from Garoua and 218 (45.6%) with no formal education. Risk factors for chronic nephropathy were highly prevalent including longstanding use of street medications (52.8%), herbal medicines (50.2%) and non-steroidal anti-inflammatory drugs (50%), alcohol consumption (34.4%), hypertension (33.9%), overweight/obesity (33.6%), hyperuricemia (16.8%), smoking (11.3%) and hyperglycemia (6.5%). The prevalence of CKD was 11.7% overall, 10.7% in Garoua and 13% in Figuil participants. Equivalents figures for CKD G3-5 and albuminuria were 2.8%, 2.0% and 4.5%; and 9.1%, 9.3% and 8.5%, respectively. History of diabetes, increase systolic blood pressure, hyperglycemia and hyperuricemia were predictors of CKD. Conclusion The prevalence of CKD is as high in these northern cities as previously reported in southern cities of Cameroon, driven mostly by known modifiable risk factors of chronic nephropathy.

Crystallization characteristics of amorphous trehalose dried from alcohol

Trehalose forms a glass that can be used to preserve labile substances under desiccation. The crystallization characteristics, namely crystallization temperature (T-cry) and isothermal crystallization behavior of amorphous trehalose, dried from alcohol (methanol, ethanol), was analyzed and the results were compared with those for the amorphous trehalose freeze-dried from water. The use of alcohol as a solvent lowered the T-cry from 184 +/- 6 degrees C for the case of an aqueous solvent to 103 +/- 5 degrees C/methanol and 120 +/- 8 degrees C/ethanol. The formation of multiple forms of crystals and partial melting were suggested by the thermal analysis. Isothermal crystallization experiments showed that the alcohol-originated amorphous trehalose was eventually exclusively converted into beta-form crystals. The induction period (t(ind)) before the start of isothermal crystallization was markedly shortened when alcohol was used as the solvent compared to water. The t(ind) values for various amorphous sugar samples including the alcohol-originated ones could be correlated with difference between T-cry and the sample temperature.

Differences in use of inhalants among sexual minorities in the USA in 2015-2018

Objectives: Inhalants are substances with underestimated abuse potential associated with cardiac problems, dizziness, seizures, and decreased level of consciousness. Inhalants are commonly used by the LGB population, who are vulnerable to their harms. US epidemiologic inhalants data are scarce. The aims of this study are to: i) investigate associations between inhalant use and sexual identity groups; ii) examine associations with use of other drugs among lesbian/gays who use inhalants. Methods: Data came from the 2015-2018 NSDUH (n = 168,560). Participants ages 18 or older were asked if they had used any inhalants in their lifetime and past-year. We investigated the associations between inhalant use with sexual identity categories heterosexual, lesbian/gay, and bisexual using logistic regression models with complex survey design. Results: Total prevalences of lifetime and past-year use of inhalants were 9.4% and 0.5%, respectively. Lesbian/ gay population (L/G) and bisexuals (B) reported higher odds of lifetime (L/G: aOR = 3.71, 95%CI = [3.19,4.30], B: aOR = 1.82, 95%CI = [1.64,2.03) and past-year (L/G: aOR = 11.57, 95%CI = [8.95,14.96], B: aOR = 2.81, 95%CI = [2.02,3.92]) inhalant use compared to heterosexuals. Among L/G, men had higher odds of lifetime (aOR = 4.11, 95%CI = [3.06,5.52]) and past-year (aOR = 15.67, 95%CI = [7.27,33.76]) inhalant use versus women. Use of marijuana (aOR = 2.76, 95%CI = [1.48,5.16]), other illegal drugs (aOR = 2.70, 95%CI = [1.60,4.56]), and non-medical use of psychotherapeutics (aOR = 2.67, 95%CI = 1.77,4.05) were associated with past-year use of inhalants among L/G. Conclusion: LGB population is at elevated risk of inhalant use and of concurrent use with other drugs. Gay men had significantly higher odds of inhalant use compared to lesbians and bisexuals. Informative and in-site harm reduction measures are warranted to prevent harms from inhalant use.

The carbon footprint of alternative jet fuels produced in Brazil: exploring different approaches

Although the potential of Alternative Jet Fuels (AJF) to reduce greenhouse gases (GHG) emissions has been widely reported upon in the literature, there are still discrepancies among the results. These may be due to the different GHG accounting methods, including those used by different Low-Carbon Policies (LCPs). To have a clearer understanding of the life cycle performance of AJF, the carbon footprint of ten pathways was estimated, comprising promising feedstocks – such as soybean, palm, sugarcane, sugarcane residues, forestry residues, used cooking oil, beef tallow, and steel off-gases – and ASTM-approved technologies: Hydroprocessed Fatty Acids, Alcohol-to-Jet, and Fischer-Tropsch. Six methodological approaches were used: the attributional and the consequential life cycle assessment, as well as guidelines for the four LCPs: Renovabio (Brazil), CORSIA (aviation sector), RFS (United States), and RED II (Europe). Soybean-based pathway (24 to 98.7 gCO(2e)/MJ) had the low to no potential for reducing GHG when compared to their fossil counterparts, mainly due to land use change. Of all food-based pathways, AJF produced from sugarcane performed the best (-10.4 to 43.7 gCO(2e)/MJ), especially when power surplus was credited. AJF from palm oil could present significant GHG reduction for palm expansion in degraded pasturelands. By contrast, Fischer-Tropsch of lignocellulosic residues showed the highest potential for reducing GHG (-95% to -130%). Different from food-based pathways, the potential GHG reduction of residues-based pathways converged within a narrower range (-130% to -50%), except when residual feedstocks have to be redirected from their current economic use. It could lead to GHG emissions higher than fossil fuel.

Temporal stability of driver injury severity in single-vehicle roadway departure crashes: A random thresholds random parameters hierarchical ordered probit approach

This study examines contributing variables affecting the driver injury-severity in single-vehicle roadway departure crashes. To capture the threshold heterogeneity and unobserved heterogeneity, the random thresholds random parameters hierarchical ordered pro bit (HOPIT) approach is employed using the crash data collected from 2014 to 2017 in the State of North Carolina. Three injury severity levels are considered: severe injury, minor injury, and no injury. Attributes that potentially affect crash severity are examined, including driver, crash, roadway, and environmental characteristics. A series of likelihood ratio tests are conducted to examine the temporal stability of factors across different studied years. The marginal effects of factors in different injury-severity models are compared. Significant temporal instability is found among the studied year periods. The threshold value estimated using the random threshold random parameters HOPIT model is found to be random parameters and determined by specific explanatory variables. Additionally, the effects of some factors (e.g., alcohol, curved roadway, passenger car, SUV, and wet/water surface) on injury severity are relatively stable, while others (e.g., female driver, collector, and clear weather) present temporal unstable effects. Regarding the temporal instability, decision-makers need to treat the factors carefully to avoid developing incorrect countermeasures. (C) 2020 Elsevier Ltd. All rights reserved.

Smoke in the air – Associations between experimentation with cannabis and the use of tobacco and nicotine products among 15-16-year-old school students

Background: Cannabis is the most popular illicit drug among adolescents in developed countries, including Finland. The aim of this study was to estimate 1) how cannabis experimentation among Finnish adolescents changed between 2003 and 2019, and 2) whether the associations between cannabis experiments and factors related to it, especially the use of tobacco and nicotine products, changed during the same time period. Methods: The analyses are based on the European School Survey Project on Alcohol and Other Drugs data, collected from Finnish adolescents aged 15 to 16 in 2003, 2007, 2011, 2015, and 2019 (N = 20,630). Results: Experimentation with cannabis among Finnish adolescents has increased since the beginning of our follow-up. At the same time, alcohol use and smoking have decreased markedly, and attitudes toward cannabis use have become more relaxed. The association between smoking and cannabis experimentation has become weaker over time. However, the use of tobacco and nicotine products, especially polytobacco, is still a strong risk factor for experimentation with cannabis. The higher the number of tobacco or nicotine products used, the higher the probability for cannabis experimentation. Conclusions: Experimentation with cannabis has previously been concentrated predominantly on adolescents who smoke, but recently non-smokers are increasingly trying cannabis. It is possible that alternative ways of using cannabis may have increased its use. Despite the strict cannabis policy in Finland, its use has increased, which may be an indication that youth cultures and images of different substances play a significant role in adolescents experimenting with cannabis.
