Authors: Bhushan Bharat , Raigar Rakesh Kumar 
Published: August 2020

AbstractEngineering properties of pulses are important for seed quality understanding, designing of food processing operations and equipment. This study seeks to carefully evaluate engineering properties of green and brown rice bean varieties on different moisture content in a range of 14–34% (db). The average length, breadth, thickness, geometric mean diameter, thousand‐seed weight, true density, porosity, angle of repose, and terminal velocity significantly (p ≤ 0 .5) increased from 8.05 to 11.32 mm; 5.02 to 6.26 mm; 4.05 to 5.27 mm; and 5.45 to 7.18 mm; 127.48 to 254.86 g; 1,016.33 to 1,410.49 kg/m3; 17.61 to 58.96%; 23.41 to 36.39°; and 6.06 to 8.54 m/s, respectively, as the moisture content increased. The bulk density significantly reduced from 875.78 to 522.19 kg/m3for both varieties, whereas sphericity of green and brown rice beans showed an insignificant and significant decrease, respectively, with increasing moisture content. The hardness at an initial moisture level for green rice bean was higher in comparison to the brown variety and later on increasing the moisture level, the hardness decreased significantly for both varieties. The static regime of frictional coefficient produced similar results for both varieties, that is, maximum on wood followed by galvanized iron, mild steel, and aluminum surface.Practical applicationsRice bean production is expanding due to the increasing demand for local customers, lower prices, and excellent nutritional availability. The strategy used for harvesting, storage, and processing is still traditional and arduous to a greater extent. Nitty‐gritty data on engineering properties of rice bean is provided in this report, which is extremely helpful in the design of equipment used in harvesting operations, unit operations, and food processing operations. In this manner, the report will help to extend the production of rice bean and diminishing human drudgery.

AbstractIntroductionRecent studies have described several cardiovascular manifestations of COVID‐19 including myocardial ischemia, myocarditis, thromboembolism, and malignant arrhythmias. However, to our knowledge, syncope in COVID‐19 patients has not been systematically evaluated. We sought to characterize syncope and/or presyncope in COVID‐19.MethodsThis is a retrospective analysis of consecutive patients hospitalized with laboratory‐confirmed COVID‐19 with either syncope or presyncope. This “study” group (n = 37) was compared with an age and gender‐matched cohort of patients without syncope (“control”) (n = 40). Syncope was attributed to various categories. We compared telemetry data, treatments received, and clinical outcomes between the two groups.ResultsAmong 1000 COVID‐19 patients admitted to the Mount Sinai Hospital, the incidence of syncope/presyncope was 3.7%. The median age of the entire cohort was 69 years (range 26‐89+ years) and 55% were men. Major comorbidities included hypertension, diabetes, and coronary artery disease. Syncopal episodes were categorized as (a) unspecified in 59.4% patients, (b) neurocardiogenic in 15.6% patients, (c) hypotensive in 12.5% patients, and (d) cardiopulmonary in 3.1% patients with fall versus syncope and seizure versus syncope in 2 of 32 (6.3%) and 1 of 33 (3.1%) patients, respectively. Compared with the “control” group, there were no significant differences in both admission and peak blood levels of d‐dimer, troponin‐I, and CRP in the “study” group. Additionally, there were no differences in arrhythmias or death between both groups.ConclusionsSyncope/presyncope in patients hospitalized with COVID‐19 is uncommon and is infrequently associated with a cardiac etiology or associated with adverse outcomes compared to those who do not present with these symptoms.

AbstractWe describe a case of pretibial dystrophic epidermolysis bullosa in a 5‐year‐old girl, her mother, and maternal great aunt. All subjects had trauma‐induced blisters and erosions, with scarring, on the knees and lower legs, and nail dystrophy of variable severity. Genetic analysis in all three patients showed a 6849del18 mutation in the COL7A1 gene, causing the production of shortened collagen VII polypeptides and resulting in a mild phenotype, with localized acral blisters and nail involvement.

AbstractBackgroundThere are two main techniques for arterial reconstruction in RT: TA using a stab longitudinal incision which creates an elliptical opening and AP which fashions a circular defect. We hypothesized that AP creates a natural anastomosis lumen, similar to the donor renal artery, which optimizes RT perfusion.MethodsA retrospective review of a single‐institution database was performed between 2000 and 2018. Twenty patients who underwent AP arteriotomy were compared to 40 TA‐matched controls. Data were collected on creatinine (preoperative, nadir, and time to nadir), and DUS RI and PSV at 1 week, 3 months, and 6‐12 months post‐RT.ResultsttNC was shorter in the AP group (5 ± 4 vs 12 ± 13 days; P = .03). PSV at 1 week was lower in the AP group (186 ± 65 cm/s vs 232 ± 89 cm/s; P = .04). There was no difference in nadir creatinine value (P = .26), preoperative creatinine (P = .66), and initial postoperative creatinine (P = .80). RI at week 1 were not different between groups (P = .37). Follow‐up DUS showed the difference in PSV between groups became non‐significant (1 month P = .50 and 6‐12 months P = .53).ConclusionsAP arteriotomy in RT improves early perfusion and function parameters (ttNC and initial PSV) as compared to TA. AP arteriotomy optimizes early allograft reperfusion, which may have important long‐term implications and deserves further evaluation.

ObjectiveAntimicrobial peptides (AMPs) play essential roles in maintaining gut health and are associated with IBD. This study is to elucidate the effect of angiogenin (ANG), an intestine-secreted AMP, on gut microbiota and its relevance with IBD.DesignThe effect of ANG on microbiota and its contribution to colitis were evaluated in different colitis models with co-housing and faecal microbiota transplantation. ANG-regulated bacteria were determined by 16S rDNA sequencing and their functions in colitis were analysed by bacterial colonisation. The species-specific antimicrobial activity of ANG and its underlying mechanism were further investigated with microbiological and biochemical methods. ANG level and the key bacteria were characterised in IBD faecal samples.ResultsANG regulated microbiota composition and inhibited intestinal inflammation. Specifically, Ang1 deficiency in mice led to a decrease in the protective gut commensal strains of Lachnospiraceae but an increase in the colitogenic strains of α-Proteobacteria. Direct binding of ANG to α-Proteobacteria resulted in lethal disruption of bacterial membrane integrity, and consequently promoted the growth of Lachnospiraceae, which otherwise was antagonised by α-Proteobacteria. Oral administration of ANG1 reversed the dysbiosis and attenuated the severity of colitis in Ang1-deficient mice. The correlation among ANG, the identified bacteria and IBD status was established in patients.ConclusionThese findings demonstrate a novel role of ANG in shaping gut microbe composition and thus maintaining gut health, suggesting that the ANG-microbiota axis could be developed as a potential preventive and/or therapeutic approach for dysbiosis-related gut diseases.
Determinants of quality of life in Rett syndrome: new findings on associations with genotype
Authors: Mendoza Jonathan , Downs Jenny , Wong Kingsley , Leonard Helen 
Published: August 2020

BackgroundRett syndrome is a genetically caused neurodevelopmental disorder associated with functional deficits and comorbidities. This study investigated relationships between genotype, functional abilities and comorbidities and quality of life in Rett syndrome.MethodsThe International Rett Syndrome Database, InterRett, was used as a sampling frame for this observational study. Information was collected to describe functional abilities (walking and feeding), health (Sleep Disorder Scale for Children, the Rett Syndrome Behavioural Questionnaire), parental health (12-item Short Form Health Survey) sociodemographic factors (parental employment and education) and quality of life (Quality of Life Inventory-Disability) for 210 individuals with Rett syndrome. Univariate and multivariate regressions were used to analyse the relationships between the independent variables and quality of life.ResultsCompared with individuals with the p.Arg270* mutation, those with the p.Arg294* mutation type had the poorest quality of life (coeff −12.81, 95% CI –23.49 to 2.12), despite this being recognised as a clinically milder genotype. Overall better walking and feeding skills and seizure parameters were more associated with better quality of life and poor sleep and behavioural difficulties with poorer quality of life.ConclusionsThese findings suggest that genotype, functioning and health each have implications for quality of life and should be considered when counselling families and planning clinical and support management strategies.

Background
Many neurointerventionalists have transitioned to transradial access (TRA) as the preferred approach for neurointerventions as studies continue to demonstrate fewer access site complications than transfemoral access. However, radial artery spasm (RAS) remains one of the most commonly cited reasons for access site conversions. We discuss the benefits, techniques, and indications for using the long radial sheath in RAS and present our experience after implementing a protocol for routine use.

Methods
A retrospective review of all patients undergoing neurointerventions via TRA at our institution from July 2018 to April 2020 was performed. In November 2019, we implemented a long radial sheath protocol to address RAS. Patient demographics, RAS rates, radial artery diameter, and access site conversions were compared before and after the introduction of the protocol.

Results
747 diagnostic cerebral angiograms and neurointerventional procedures in which TRA was attempted as the primary access site were identified; 247 were performed after the introduction of the long radial sheath protocol. No significant differences in age, gender, procedure type, sheath sizes, and radial artery diameter were seen between the two cohorts. Radial anomalies and small radial diameters were more frequently seen in patients with RAS. Patients with clinically significant RAS more often required access site conversion (p<0.0001), and in our multivariable model use of the long sheath was the only covariate protective against radial failure (OR 0.061, 95% CI 0.007 to 0.517; p=0.0103).

Conclusion
In our experience, we have found that the use of long radial sheaths significantly reduces the need for access site conversions in patients with RAS during cerebral angiography and neurointerventions.

Published: August 2020

BackgroundThe objective of this study is to estimate the sensitivity of cigarette quantity demanded to price and income changes in Montenegro.Data and methodsThe sensitivity of cigarette quantity demanded to price and income changes was estimated using micro and macro analysis. Micro analysis implied the use of Deaton’s model on Household Budget Survey data (2006–2017). In macro analysis, conventional static demand model is applied using error correction and autoregressive distributed lag time series methodology on annual time series aggregated data (2001–2017).ResultsThe same results were obtained using micro and macro analysis which contributes to the objectivity of the conducted research. Results derived from the Deaton’s model indicate a negative price elasticity of cigarettes in the range between −0.62 and −0.80 (conditional and unconditional), while in macro model estimated price elasticity is in that range and equals −0.68. Simulation results confirm the efficiency of excise tax policy changes, having an evident decrease in consumption and increase of public revenues.ConclusionAnalysis of the tobacco market and regulatory environment suggests that the increase of excise and other taxes on tobacco have an important direct impact on the reduction of cigarettes and other tobacco products consumption. Our estimates of long and short-run price elasticity show that direct impact is strong and very much in accordance with the results obtained so far for other low-income and middle-income countries. This paper gives a contribution to the analysis of price elasticity of demand for cigarettes, which was for the first time conducted in Montenegro.

Published: August 2020

BackgroundBosnia and Herzegovina (B&H) is among the top 10 countries in the world in terms of number of smokers. The cigarette prices in B&H are under a direct impact of state excise tax policy. The specific excise on cigarettes was introduced in B&H in 2009. Since then it has been increasing every year thus being the main driver of cigarette prices growth.MethodsIn this paper we estimate price elasticity of demand for cigarettes following Deaton demand model and apply it on microdata obtained from the Household Budget Surveys in B&H conducted in 2011 and 2015. Deaton model uses within-cluster information to estimate total expenditure elasticities and then uses between-cluster information to estimate price elasticities. For B&H, the cluster is defined as a municipality × in the year t. Our sample contains 14 252 households, divided into 267 clusters.ResultsOur results show that the price elasticity is statistically significant and amounts to −1.366. This means that if cigarette prices in B&H are increased by 10%, the demand for cigarettes would decrease by 13.66%.ConclusionsWe found a negative price elasticity of demand for cigarettes of −1.366. These results of the econometric estimate of elasticity of demand are more elastic compared with the results of similar surveys carried out on the sample of low and middle-income countries. It demonstrates that the demand for cigarettes responds strongly to the price increase.
Exaggerated pressor response to blood flow restriction resistance exercise is associated with a muscle metaboreflex-induced increase in blood pressure in young, healthy humans

Published: August 2020

Some researchers are concerned that exercise training with the blood flow restriction (BFR) technique induces an exaggeration in blood pressure response and potentiates adverse cardiovascular events. In the present study, we demonstrate that the blood pressure response to arm-curl exercise was intensified by the BFR technique, and the degree of intensification was associated with a blood pressure response to postexercise muscle ischemia of the elbow flexors, which elicit a muscle metaboreflex. Novelty: BFR technique intensifies blood pressure response to exercise, which was associated with a blood pressure response in postexercise muscle ischemia-induced muscle metaboreflex.

Published: August 2020

This study investigated differences in forest structure, organic layer thickness, soil organic carbon, and permafrost depth between late-successional (LS) and postfire (PF; 90–120 years since burn) plots under black spruce (Picea mariana (Mill.) B.S.P.) growing on fine-textured, poorly drained lacustrine sediments in the Copper River Basin, Alaska. Although live stem and seedling density and organic layer thickness were not significantly different between PF and LS plots (28 ± 7 cm and 31 ± 10 cm, respectively), we did find a significant difference in soil organic carbon (SOC) stocks (30 ± 10 kg·m−2 and 46 ± 12 kg·m−2, respectively) permafrost depth (90 ± 28 cm and 56 ± 12 cm, respectively). OLT was linearly related to 1 m SOC stocks for LS plots but not for PF plots, and LS plots had a greater proportion of highly decomposed (humic) material in the organic layer. The soil properties of PF plots appear to be on a trajectory of recovery toward those of LS plots with respect to SOC stocks, permafrost depth, and organic layer composition. However, PF plots remain different despite nearly 100 years since fire disturbance and thus they are potentially more sensitive to changes in future fire frequency or climate.
Glow discharge excited at low to high radio frequencies around active dipoles in the ionosphere
Authors: James H. Gordon , Yau Andrew W. 
Published: August 2020

We present the first space-borne observation of optical emissions of both neutral and ionized argon atoms resulting from a radio-frequency glow discharge (RF-GD) from a sounding rocket payload. The Observations of Electric-field Distributions in the Ionospheric Plasma — a Unique Strategy-C (OEDIPUS-C) payload was designed to separate into two sub-payloads on its up-leg. This separation permitted a number of two-point measurements, including those on radio wave propagation from the active dipole antennas on the upper sub-payload to the synchronized receiving dipoles on the lower sub-payload. A white-light video camera on the lower sub-payload recorded strong luminosity around the active dipoles during the first 15 s after sub-payload separation, when argon gas jets were providing propulsion to separate the two sub-payloads. Parts of the ejected argon appeared as a glowing volume where the large radio-frequency (RF) fields from the two active dipoles excited the optical emission, as the sub-payload separation increased from 2 to 55 m. The shape and intensity of the luminosity were well repeated as a function of the swept frequency (0.025–8.000 MHz), but their frequency dependences were distinctly different from those of sounder-accelerated electrons measured onboard, and deduced to result from the nonlinearity of the glow discharge. The observation is to our knowledge the first of its kind, and is interpreted in terms of a RF-GD energized by the strong near electric fields of the transmitting dipoles.

In this study, we investigate the effect of fluorine (F[Formula: see text] flow rate on the crystal characteristics and chemical bonds of Al-Doped ZnO (AFZO) Films. At first, 1 wt% Al2O3was mixed with 99 wt% ZnO to form the Al-doped ZnO ceramic target, the radio frequency (RF) magnetron sputtering method was used to deposit the AFZO films by introducing different flow rates of F2gas using F2/(Ar + F2) mixing atmosphere during the deposition process. F2flow rates (F2/(Ar + F2)) were changed in the range of [Formula: see text]%, and F2ratio was controlled using the mixing gases of (F2(5%) + 95% Ar) and pure Ar. AFZO films were deposited on the EagleXG glass and the films’ thickness was about 330 nm by controlling the deposition time. After AFZO films were deposited, their crystalline structure and electrical characteristics were well investigated. Finally, a comparative study of surfaces of AFZO films was investigated using X-ray photoelectron spectroscopy (XPS) to find the variations of the chemical bonds as the deposition temperature and F2flow rate were changed.

Published: August 2020

We introduce the novel technical results of the enhanced logging system for customer virtual machines (VMs) in an Infrastructure as a Service (IaaS) cloud. The main contribution is that the enhanced system can work with a better system's accuracy and speed, with the simplicity of the design and implementation. We measure the accuracy of the unenhanced logging system, then find a quick solution to enhance the system based on the results of the measurement. To measure and enhance the unenhanced system, we increase the main memory and CPU cores of the VMs then collect the accuracy results from each increment configuration. We analyze the results and propose to use the taskset tool to enhance the accuracy of the system. Found three main findings include: firstly, the accuracy of the enhanced system is about 20% on maximum better than the unenhanced one; the enhanced system accuracy becomes 100%; lastly, the enhanced system can detect a file with the smaller file size as almost 12% smaller. The findings can be a basis to design the logging systems in an IaaS cloud, to decrease hardware and energy investment. To the best of our knowledge, the contribution and findings are not in the literature.

Published: August 2020

Resistive leakage current based condition assessment of metal oxide surge arrester (MOSA) is one of the most extensively employed technique to monitor its degradation. An extraction method is customarily required to extract the resistive component from the total leakage current. The existing methods to extract the resistive current are complex and less accurate. Therefore, this paper describes a simple and accurate circuit-based method to extract the resistive current using equivalent model and measured leakage current of the arrester. The accuracy of the proposed method is validated through experimental results on ABB’s 120 kV surge arrester, EMTP and QuickField software simulations. The performance of the method is also analyzed and verified experimentally on 72, 180 and 240 kV rated ABB’s surge arresters. The obtained results of resistive leakage current have shown the maximum error of 0.001%. Simple and easier computational steps with higher accuracy are the key benefits of the proposed technique.
