Published: June 2021

Abstract
In the cold spray process, cross-sectional shape of the nozzle has a significant effect on spray pattern of coatings. The circular exit nozzle is parabolic in shape. So, spray pattern with the rectangular nozzle is wider than that with the circular spray nozzle. The goal of this investigation is to establish a design for the cold spray gun nozzle to gain more uniform spray profile of coatings. We have investigated the influence of expansion ratio, nozzle total length and the ratio of nozzle length of divergent section and parallel section of rectangular nozzle on behaviors of gas and particle by the computational fluid dynamics (CFD) in high pressure cold spraying. We have studied copper particles so far. In this study, we will examine aluminum particles. First, we investigate the influence of the size and shape of the rectangular section nozzle on the velocity, temperature, and particle distribution of aluminum particles by CFD. After that, the rectangular section nozzles were fabricated and coating formation experiments were conducted, spray patterns and coating cross-sectional structures were observed, and coating adhesion was also evaluated. The nozzle material was polybenzimidazole resin, which is difficult for aluminum particles to attach to nozzle walls.
Parametric Redesign of a Convergent-Divergent Cold Spray Nozzle
Authors: Zavalan Florentina-Luiza , Rona Aldo 
Published: June 2021

Abstract
The generation of a high velocity carrier gas flow for cold metal particle applications is addressed, with specific focus on titanium cold spraying. The high hardness of this material makes cold spraying titanium difficult to achieve by industry standard nozzles. The redesign of a commercial conical convergent-divergent cold spray nozzle is achieved by the application of aerospace design codes, based on the Method of Characteristics, towards producing a more isentropic expansion by contouring the nozzle walls. Steady three-dimensional RANS SST k-ω simulations of nitrogen are coupled two-way to particle parcel tracking in the Lagrangian frame of reference. The new contoured nozzle is found to produce higher particle velocities with greater radial spread, when operated at the same conditions/cost of operation as the commercial nozzle. These numerical results have shown the potential for extending cold spray to high density and low ductility particles by relatively minor rig modifications, through an effective synergy between gas dynamics and material science.
Computational and Experimental Analysis of the Phenomenological Gas Flow Behavior and Particle Kinematics During Low Pressure Cold Spraying

Published: June 2021

Abstract
In this paper, the phenomenological behaviour of gas flow and particles motion during cold spraying has been studied. Observations of particles behaviour show two features: a uniform jet over a short distance ahead of the nozzle exit and then, a progressive dispersion. These behaviours are explained using a computational analysis based on a direct numerical simulation of the gas flow and the kinematic interactions with the particles. The CFD computation demonstrates that the gas stream starts to be unstable inside the nozzle with more turbulence as it moves towards the exit of the nozzle. The flow is self-oscillated along the flow direction and drives the motion of the Cu particles outside the nozzle. The zone of gas flow instability does correspond to the zone of experimental particle dispersion. Outside the nozzle, the particles form a straight jet over a certain distance that corresponds to the zone of the experimental uniform particles jet. Then, they are deviated and become more and more dispersed towards a very sparse jet along the flow direction. This phenomenon is explained by a Magnus lift force that deviates the particles trajectory when the gas flow becomes highly turbulent while developing a vorticity shedding.

Authors: Rahmati Saeed , Jodoin Bertrand , Veiga R.G.A. , Zúñiga A. 
Published: June 2021

Abstract
In this study, a new physically-based finite element approach is proposed to model and predict the superficial oxide layer removal and the occurrence of localized metallic bonding during particle impacts. The process physics, based on explosive welding theory and experiments, and method implementation is presented. Prediction of critical velocity of copper is obtained and compared to experimental data to validate the model. Moreover, the model is also able to show the bonding locations at the interface between particles and substrate. The predicted bonding locations are consistent with experimental data from literature for several metals.

Published: June 2021

The paper considers the methodology of individualization of training based on adaptive testing of network electronic educational and methodological complexes in two closely interrelated levels – the methodology of designing, developing adaptive tools and the methodology of their application in teaching university students. The design of an adaptive network electronic educational and methodological complex – a universal educational resource that is able to support the learning process at all its stages-contains three consecutive stages (levels) – didactic, logical and physical, each of which has a content component of the developer's activity that determines the requirements for the structure and content of the created course. The methodological approaches to the use of an adaptive network course in the educational process are different for teachers and students. As criteria for evaluating the effectiveness of learning content assimilation in the information and communication educational environment of the university, the following are defined: transient process time response, which a student spends for learning of fixed stream of input information until prepared for the testing (E.A. Solodova's adaptive learning mathematical model); the level of assimilation of the information received, defined in tests and evaluated in a 100-point scale (as the condition of completeness of the educational process, according to V.P. Bespalko).

В XVIII в. на основании общего интереса к святыням Востока, а также единой тенденции для крупных монастырей изготавливать гравюры на память для паломников, многие греческие гравюры свидетели русско-афонских отношений попадают на территорию Российской Империи. Сохранились такие гравюры и в Церковноархеологического кабинете Московской духовной академии, собрание которых насчитывает 29 эстампов. Пять гравюр из этого собрания имеют надписи на греческом и на славянском языке. Надписи свидетельствуют о месте и времени создания гравюры, о граверах и заказчиках, являются источниками кратких исторических сведений. В статье приведены выявленные дополнительные факты об этих гравюрах, которые свидетельствуют о наличии церковных, экономических и политических отношений на базе культурных связей между Российской Империей и странами православного Востока.

Introduction Early defibrillation remains the highest priority in the chain of survival for out-of-hospital cardiac arrest. Shock delivery should be performed within 5 minutes of collapse to achieve a 50% survival rate. Google Maps has been one of the most popular mobile navigation applications worldwide. Our primary objective was to assess the efficacy of Google Maps in locating nearby public automated external defibrillators (AEDs). Methods Local and non-local populations were enrolled. Participants were randomly assigned to locate AEDs with or without the assistance of Google Maps. Participants used Google Maps on the same smartphone and cellular data network, an activity tracker recorded data for distance covered and time required to retrieve the AED. AEDs were located within 150 seconds of the starting point. Results Out of 100 recruited participants there was no difference in baseline characteristics. In the local population group, Google Maps assistance did not show statistical significance in successfully locating the AED within 150 seconds. Correspondingly, the travel time also showed no difference (173.52 ± 50.99 seconds for Google Maps vs. 206.20 ± 159.53 seconds for control group). The result in the non-local population group revealed no significant difference in successfully locating AEDs within 150 seconds: Google Maps (18.52%) vs. control group (39.13%); p=0.126. The recorded travel time between the Google Maps group and control group were similar (307.59 ± 220.10 seconds vs. 284.0 ± 222.37 seconds; p=0.709). Conclusion In Thailand, using Google Maps mobile assistance was found to be unhelpful in accessing nearby public AEDs.

A Klebsiella pneumoniae (bactéria gram negativa e imóvel) é encontrada no trato intestinal de mamíferos. Quando ocorre um desequilíbrio as bactérias multiplicam-se intensamente, ocasionando doenças infecciosas. Portanto o objetivo deste artigo é correlacionar à prevalência dos isolados de animais, com a microbiota existente nas mãos dos proprietários, alertando sobre o risco da transmissão cruzada. Foram utilizados 114 cães para coleta de amostras, realizadas em diferentes sítios anatômicos e das mãos do proprietário, utilizando swabs estéreis umedecidos em 2 mL solução de salina tamponada (PBS) colocados em um tubo de ensaio. Posteriormente, 0,1 mL de cada diluição foram cultivadas nas placas de ágar MacConkey incubadas em condições de aerobiose à temperatura de 37°C por 24 horas. Em seguida foram realizadas provas bioquímicas e utilização de ágar cromogênico para triagem das amostras suspeitas de Klebisiella spp. Depois, foi realizada identificação por meio de espectrofotometria de massa. Foram coletadas, de 114 cães, 456 amostras de diversos sítios anatômicos entre animais e tutores. Das 456 amostras, 70 (15,35%) apresentaram características semelhantes às de Klebsiella spp após triagem em provas bioquímicas e no Chromagar. Em relação ao número de amostras, das 70 sugestivas de Klebsiella, 9 amostras (12,85 %) foram confirmadas. Com o presente estudo, foi confirmada a presença de Klebsiella pneumoniae em oito cães e em um tutor. E, ainda, constatou-se que mais estudos são necessários para desvendar a possibilidade de transmissão, assim como o mecanismo para que isso ocorra.

To analyze the pathophysiological aspects of lupus mastitis (LM), clinical presentation, epidemiology, radiological and histological findings, and treatment, to disseminate it to the academic community and draw attention to this pathology as one of the differential diagnoses in the management of breast lesions in males, especially in the case of breast cancer in men. A literature review was done by searching scientific studies in the PubMed / Medline, Scopus, Scielo, Embase, Web of Science, and Google Scholar databases. Relevant scientifically validated studies related to lupus mastitis in men were selected. The analysis, review and selection of articles carried out in pairs, blindly and separately, based on the reading of the title and abstract, with a third reviewer in case of disagreement. The LM should be suspect in patients known to have lupus erythematosus who present painful breast nodules associated with skin changes. However, LM can be the initial manifestation of lupus and mimic, both clinically and imaging, malignant neoplasms. The histopathological diagnostic criteria are well-established, finding mainly hyaline fat necrosis and lymphoplasmacytic infiltrate. Treatment must be drug-based as invasive procedures can exacerbate the injury. Due to physiological and anatomical aspects, this condition can appear and evolve differently in men. The knowledge of this pathology is necessary to carry out the correct approach since the non-identification of the disease and its erroneous management can lead to complications and irreversible sequelae to the patient.
