Evaluation of tensile strength in riveted, adhesive and hybrid joints
Authors: Chakradhar K V P , BalaRaju A , Veerapaneni Anil Kumar 
Published: December 2020

AbstractMany automobile industries prefer hybrid joining practices in the part-assembly of advanced lightweight automobile and commercial vehicles. The main cause for this is the greater need for mixed material design. One of the combinations is composite with aluminium, like a combination of Titanium-Aluminium, CFRPs with aluminium etc. This paper deals with comparative study of mechanical strength evaluation in riveted joints, adhesive joints and hybrid single-lap joints. Hybrid joints are a combination of riveted and adhesive joints. The riveted joint produces enormous stress around the holes of the fasteners, which is detrimental to its performance. The adhesive joint allows good load distribution; however, it leads to plastic deformation that is detrimental in the long run. The hybrid joint has better load bearing capacity when compared to the riveted or adhesive joints. Thus, the study indicates that a hybrid joint has better properties suitable for structural, automobile and aerospace applications.

Abstract
A airbrake make use of multiple rotors for CC brakes, coupled with stators. A rotor is sourced by spokes, and the brake system provides protection for the stators. Pressing the brakes along with the hydraulic actuators performs braking action and the frictional torque is provided to stop aircrafts from overheating disc brakes. A friction between the rotating and stationery disc causes them to heat up to around 500 °C with a surface temperature of 2000 °C. He3nce, the materials used in this environment should show high thermal shock resistance. This paper focuses primarily on the study and evaluation of the effect of alkaline earth acetates on the catalytic oxidation of Carbon Composites aircraft brakes.

Published: December 2020

Abstract
The Shielded Metal Arc Welding (SMAW) is a joining technique in which melting and joining of metals with the help of an arc between the workpiece and the filler rod. The core purpose of the paper is to examine the mechanical characteristics of welded metal under various standalone parameters like type of filler material, electrode diameter, and current for SMAW. This paper employed the half factorial Design of Experiment (DOE) using Taguchi L4 array. Varieties of welding filler materials used were E6013 and E7016, with an electrode diameter of 3.15mm and 4mm and the welding current of 90A and 110A. The desired output variables were tensile strength and Rockwell hardness of the welded joint. This paper found that when electrode diameter increases, the deposition rate increases, and hence HAZ increases, which decreases the weld strength. Using the welding filler E7016, we can obtain the maximum tensile strength for welded metals.

Abstract
Consequence modeling of ethyl acetate 40 KL aboveground storage tank was carried out under different scenarios. The toxic concentration of ethyl acetate beyond IDLH (i.e. 2000 ppm) covered up to 23 meters from the release source when there was a leak that occurred 2 inches from the bottom of the tank. The flammable vapor cloud enveloped up to 13 meters from the release source when the concentration of ethyl acetate was beyond 60% of LEL (i.e.13080 ppm). The mass of the fire ball was considered as 100% in order to get the worst case scenario during BLEVE. Based on the mass of the methyl acetate the diameter and duration of the fire ball was 190 meters and 12 seconds respectively during BELVE.

Highly reflective optical nanocavities for structural coloration by combining broadband absorber and Fabry–Pérot effects
Authors: Rossi Stefano , Jonsson Magnus P 
Published: December 2020

Abstract
Reflective structural colors are of interest for many applications as alternatives to dyes and pigments and many different solutions have been proposed. The ideal systems should provide high reflectance efficiency while keeping good chromaticity and offering tunability throughout the visible spectral range. It is challenging to achieve such combined features with a simple single structure. Here we address this challenge using a concept that combines the Fabry–Pérot effect with a broadband absorbing layer. Our easy-to-fabricate structures form highly reflective optical nanocavities with improved chromaticity throughout the visible compared with the two separate concepts. The addition of an additional cavity layer and a transparent top coating further improves the chromaticity and allows the formation of black surfaces.

Authors: Velasco V , Neto M B Silva 
Published: December 2020

Abstract
We formulate the problem of unconventional d − wave superconductivity, with phase fluctuations, pseudogap phenomenon, and local Cooper pairs, in terms of a synchronization problem in random, quantum dissipative, elasto-nuclear oscillator networks. The nodes of the network correspond to localized, collective quadrupolar vibrations of nuclei-like, elastic inhomogeneities embedded in a dissipative medium. Electrons interacting with such vibrations form local Cooper pairs, with a superfluid d − wave pseudogap Δ

Authors: Carr-Lopez Sian M , Strohecker Lorrie , Miyahara Randell , Mai Yvonne , Shek Allen 
Published: December 2020

Abstract

Purpose
The Department of Veterans Affairs (VA) Northern California Health Care System (NCHCS) uses a dashboard to identify monitoring needs for veterans prescribed chronic opioid therapy (COT). Schools of pharmacy require introductory pharmacy practice experiences (IPPEs); however, resources for providing IPPEs at medical facilities are limited. This article describes collaboration by a primary care service and a school of pharmacy to provide services for patients prescribed COT through remote access to the VA electronic health record (EHR) system.

Summary
Pharmacy students in a required population health IPPE provided clinical services for veterans remotely. Students were supervised by VA clinical pharmacists and granted remote EHR access privileges. Using personally owned laptops and VA cell phones, students performed prescription drug monitoring program (PDMP) activities, reviewed urine drug screening (UDS) results, called patients to assess pain, and documented progress notes. Students completed an assessment on the first and final days of the experience; a retrospective analysis was conducted to examine differences in student knowledge of and confidence in providing COT-focused services. The dashboard scorecard and student workload were tracked over a 1-year period. In that year, 143 students wrote 7,001 PDMP notes, reviewed 6,130 UDS results, and documented 202 pain assessments. Statistically significant improvements were reported in students’ level of confidence in performing population health activities for patients prescribed COT, including interpreting PDMP and UDS results and talking with patients.

Conclusion
The ongoing collaboration provides real-world population management experiences for future pharmacists and supports monitoring requirements for veterans prescribed COT. The program has helped NCHCS accomplish its teaching mission without dedicating clinic workspace or computers and gain an additional team to address quality measures and support population health activities.
Intubator Performance and Contamination with the Use of Barrier Enclosure Devices: Results from a Simulated COVID-19 Resuscitation
Authors: Ben-Yakov Maxim , Price Courtney , Dharamsi Alia , Tawadrous Davy , Choi Joseph M 
Published: December 2020

Abstract

Introduction
Medical institutions are using barrier enclosure devices during intubation procedures and other aerosol-generating medical procedures without evidence of their effectiveness or usability, potentially compromising patient care, and provider safety. Our objective was to determine the degree of protection offered by these devices and explore other usability factors for two popular barrier systems.

Methods
A simulated trial comparing an intubation box, a frame and plastic tarp system, and unprotected intubation was performed in an academic emergency department. Ten emergency physicians were recruited to participate. Our primary outcome was the degree of contamination from secretions measured by average surface area exposed to phosphorescent material. Secondary outcomes included: laryngoscopy time and time to barrier application, unsuccessful intubation attempts, and usability ratings for each system. Descriptive statistics were reported for all variables of interest and a linear mixed model was used to analyze contamination and laryngoscopy time. Usability was captured through electronic questionnaires using a five-point Likert scale.

Results
Contamination was more prevalent with the box, compared to the frame and tarp, and no device, however, this did not achieve statistical significance (13.2% versus 8.1% versus 12.2%, P = 0.17). A barrier system delayed intubation when compared to using no system (no system = 24.4 s [95% CI 17.3–27.5], frame = 54.4 s [95% CI 13.8–95.0], box = 33.8 s [95% CI 21.4–46.1], P = 0.02). In assessing usability, 30% of users preferred the use of a box barrier, 40% of users preferred the frame, and 30% would not use either in future intubation.

Conclusions
Compared to no barrier protection, an intubation box enclosure offers limited additional protection. A frame and tarp system reduces exposure at the expense of visibility and operator comfort. Finally, barrier systems do not appear to have a clinically significant impact on airway management.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic, caused by the coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has created an unprecedented threat to public health. The pandemic has been sweeping the globe, impacting more than 200 countries, with more outbreaks still lurking on the horizon. At the time of the writing, no approved drugs or vaccines are available to treat COVID-19 patients, prompting an urgent need to decipher mechanisms underlying the pathogenesis and develop curative treatments. To fight COVID-19, researchers around the world have provided specific tools and molecular information for SARS-CoV-2. These pieces of information can be integrated to aid computational investigations and facilitate clinical research. This paper reviews current knowledge, the current status of drug development and various resources for key steps toward effective treatment of COVID-19, including the phylogenetic characteristics, genomic conservation and interaction data. The final goal of this paper is to provide information that may be utilized in bioinformatics approaches and aid target prioritization and drug repurposing. Several SARS-CoV-2-related tools/databases were reviewed, and a web-portal named OverCOVID (http://bis.zju.edu.cn/overcovid/) is constructed to provide a detailed interpretation of SARS-CoV-2 basics and share a collection of resources that may contribute to therapeutic advances. These information could improve researchers’ understanding of SARS-CoV-2 and help to accelerate the development of new antiviral treatments.

Published: December 2020

Abstract
Accurately identifying potential drug–target interactions (DTIs) is a key step in drug discovery. Although many related experimental studies have been carried out for identifying DTIs in the past few decades, the biological experiment-based DTI identification is still timeconsuming and expensive. Therefore, it is of great significance to develop effective computational methods for identifying DTIs. In this paper, we develop a novel ‘end-to-end’ learning-based framework based on heterogeneous ‘graph’ convolutional networks for ‘DTI’ prediction called end-to-end graph (EEG)-DTI. Given a heterogeneous network containing multiple types of biological entities (i.e. drug, protein, disease, side-effect), EEG-DTI learns the low-dimensional feature representation of drugs and targets using a graph convolutional networks-based model and predicts DTIs based on the learned features. During the training process, EEG-DTI learns the feature representation of nodes in an end-to-end mode. The evaluation test shows that EEG-DTI performs better than existing state-of-art methods.

Abstract

Motivation
One avenue to address the paucity of clinically testable targets is to reinvestigate the druggable genome by tackling complicated types of targets such as Protein-Protein Interactions (PPIs). Given the challenge to target those interfaces with small chemical compounds, it has become clear that learning from successful examples of PPI modulation is a powerful strategy. Freely accessible databases of PPI modulators that provide the community with tractable chemical and pharmacological data, as well as powerful tools to query them, are therefore essential to stimulate new drug discovery projects on PPI targets.

Results
Here, we present the new version iPPI-DB, our manually curated database of PPI modulators. In this completely redesigned version of the database, we introduce a new web interface relying on crowdsourcing for the maintenance of the database. This interface was created to enable community contributions, whereby external experts can suggest new database entries. Moreover, the data model, the graphical interface, and the tools to query the database have been completely modernized and improved. We added new PPI modulators, new PPI targets and extended our focus to stabilizers of PPIs as well.

Availability and implementation
The iPPI-DB server is available at https://ippidb.pasteur.fr The source code for this server is available at https://gitlab.pasteur.fr/ippidb/ippidb-web/ and is distributed under GPL licence (http://www.gnu.org/licences/gpl).
