BACKGROUND AND OBJECTIVES
Because of the coronavirus disease 2019 pandemic and recommendations from a range of leaders and organizations, the pediatrics subspecialty 2020 recruitment season was entirely virtual. Minimal data exist on the effect of this change to guide future strategies. The aim of this study was to understand the effects of virtual recruitment on pediatric subspecialty programs as perceived by program leaders.

METHODS
This concurrent, triangulation, mixed-methods study used a survey that was developed through an iterative (3 cycles), consensus-building, modified Delphi process and sent to all pediatric subspecialty program directors (PSPDs) between April and May 2021. Descriptive statistics and thematic analysis were used, and a conceptual framework was developed.

RESULTS
Forty-two percent (352 of 840) of PSPDs responded from 16 of the 17 pediatric (94%) subspecialties; 60% felt the virtual interview process was beneficial to their training program. A majority of respondents (72%) reported cost savings were a benefit; additional benefits included greater efficiency of time, more applicants per day, greater faculty involvement, and perceived less time away from residency for applicants. PSPDs reported a more diverse applicant pool. Without an in-person component, PSPDs worried about programs and applicants missing informative, in-person interactions and applicants missing hospital tours and visiting the city. A model based upon theory of change was developed to aid program considerations for future application cycles.

CONCLUSIONS
PSPDs identified several benefits to virtual recruitment, including ease of accommodating increased applicants with a diverse applicant pool and enhanced faculty involvement. Identified limitations included reduced interaction between the applicant and the larger institution/city.

The sweet potato (Ipomoea batatas L.) is a vegetable of great economic importance since it can be used for in natura consumption, for processing in agribusiness and/or biofuel production. The objective of this work was to evaluate the yield of three sweet potato cultivars: BRS Amelia, BRS Cuia and BRS Rubissol in the Northwest Region of Rio Grande do Sul. The experiment was conducted in the field for two consecutive years (harvests 2014/2015 and 2015/2016). The experimental design was in randomized blocks, evaluating 3 sweet potato cultivars for 2 agricultural years, with 4 replications. As results, it was observed that potato weights in the first year of study ranged from 272.0 g to 320.2 g. In the second year of evaluation, it ranged from 133.9 g to 247.1 g. In relation to the average productivity, the values obtained in the first year were 15.2 t ha-1 for BRS Amelia, 19.8 t ha-1 for BRS Cuia and 16.2 t ha-1 for BRS Rubissol. In the second year of evaluation, the values were 12.3 t ha-1 for BRS Amelia, 16.1 t ha-1 for BRS Cuia and 13.1 t ha-1 for BRS Rubissol. Cultivars presented yields higher than the national average from Brazil in the two evaluated years.

Electrolyzed oxidizing water is an eco-friendly emerging technology considered as a novel broad-spectrum sanitizer. The efﬁcacy of electrolyzed oxidizing water against Colletotrichum gloeosporioides, Fusarium oxysporum, and Penicillium italicum at different concentrations of free chlorine (0.5, 1, 6, 12, and 30 ppm) was evaluated. The results showed that at concentrations of 6, 12, and 30 ppm of free chlorine the mycelial growth, sporulation and germination process were totally inhibited in the strains tested. The inoculated fruit application of treatments by applying 30 ppm of free chlorine presented the best results for fungus control on artificially inoculated banana, papaya, and Persian lime fruits. The fruit quality (weight loss, TSS, pH, titratable acidity) was also evaluated. The application of electrolyzed oxidizing water had not negative impact on fruit quality. The results obtained confirm the antifungal activity of electrolyzed oxidizing water against the strains tested, as well as its capacity to cure infected fruits.

Published: September 2022

Panasonic NCR18650B (LiNi0.8Co0.15Al0.05O2) lithium-ion power cell (LIPC) and its performance after exposure to excess direct current are considered in this paper. The basic fire hazard indicators (element ignition temperature, flame temperature, element heating time, etc.) were experimentally established and mathematically confirmed for the examined LIPC.
According to the results of experimental studies, the time of occurrence of an irreversible thermochemical reaction in a lithium-ion power cell was determined depending on the different DC current strengths. Additionally, the critical temperature of the onset of an irreversible thermochemical reaction and the total combustion temperature of the element have been established. The application of the Joule-Lenz and Fourier laws allowed for a mathematical notation of the dependence (influence) of DC strength over time and the heating of the element to a critical temperature.
The heating time of Panasonic NCR18650B LIPC (LiNi0.8Co0.15Al0.05O2) to a critical temperature of 100–150 °C under the influence of excess current was experimentally established and mathematically confirmed.
The determined critical indicators of the element (temperature, time, etc.) make it possible to further devise a number of necessary regulatory documents that will allow them to be certified, tested, and, in general, to better understand the dangers that they may pose. A mathematical model was built, which, taking into account the geometrical parameters of the element, makes it possible to calculate the onset of the critical temperature of such elements with excellent geometric parameters without conducting experimental studies

The object of this study is the structural and technological parameters of the gas blower unit in the gasification chamber of a gas generator. The task to enable uniform distribution of air masses in the gas generator has been solved using the ANSYS Fluent software. The study is based on a simulation of the movement of air flows in the characteristic cross-sections of the gas generator, in particular the cross-section of the gasification chamber at the border of the oxidation and reduction zones. Seven structures of the gas blower unit were analyzed, the effectiveness of which was determined by the coefficient of variation. The most effective was the design whose value of the coefficient of variation is the smallest and equal to 93 %. At the same time, the total area of zones with no movement of air masses, that is, the absence of a gasification process, does not exceed 12 % of the total cross-sectional area of the gas generator. The speed of air masses at the boundary of the oxidation and reduction zones is aligned in the entire cross-section of the chamber and is V»4.5 m/s. The average value of the vertical component of the speed of air masses in the cross-section at the inlet to the recovery zone of the gasification chamber is V»0.6 m/s. Under such conditions, the production of synthesis gas of high calorific value with the absence of resins, acids, heavy hydrocarbons, and mechanical impurities is ensured. The correspondence of the simulation results with experimental data is confirmed by the coefficient of determination, which amounted to 0.87.
The results reported here could be the basis of a modernized methodology for the study of aerodynamic, heat and mass exchange processes that occur during biomass gasification. This would make it possible to define the rational structural and technological parameters of gas generators and improve the efficiency of the gasification process as a whole.

Published: September 2022

In recent years, the demand for high-durability parts are rising too much. These challenges are difficult to overcome without an innovative framework based on an accurate database. The problems of high stress generated due to the hard friction and severe crystal dislocation during the forming process need to be solved. High frictional forces between the contact surfaces while forming lead to high sticking between the parts. In this work, forming process of the large sheet metal has been explored based on some parameters like material properties, stress generation, and their effects on the product quality. For this purpose, square sheet metal of 721*721*5 mm is considered, and the product formation through many forming steps was carried out. This work includes adopting some design steps, modeling, and analysis to control some parameters and minimize the generation stresses. The finite element software (ABAQUS/CAE) has been adopted for analyzing this process. In this simulation, the forming process evolution in different steps has been analyzed, and the influence of the effective parameters was performed. As a result, it’s found that the generation stresses are highly concentrated near the fillet zones and proportional to the pressure, and depend on the nature of contact and friction. Simulation results also revealed that the uniform pressure during forming will leads to minimizing the friction and stress generation (5 %) and this will improve the product quality. Also, it’s possible to identify and facilitate many difficulties and evaluate the possibilities before further investing in tooling. It’s concluded that any accurate process like this must depend on some sequence steps like design, modeling, and simulation. Moreover, folding the large surface area needs accurate and adjustable types of equipment.

This paper considers and analyzes a relevant issue of treatment of disturbed soils. The equipment to carry out various processes of mining reclamation of waste heaps and quarries with a significant reduction in the level of environmental risks through the operation of an energy-saving small-sized apparatus has been designed. The use of the developed soil reclamator is also adequate for pre-sowing and other types of agrotechnical tillage, plant care in agricultural fields, as well as in areas with a heterogeneous landscape. The functionality of the unit is able to provide energy autonomy and automation of the technological process. The low weight of the device makes it possible to reduce the pressure on the soil, which minimizes the environmentally hazardous formation of dust during the treatment of waste heaps, the destruction of its structure, the machine degradation of the fertile layer during the processing of all types of territories. The device also reduces the risk of fertile soils slipping from the slopes of mine dumps due to the fact that the soil reclamator is self-propelled and functions without the need to involve a heavy tractor. The mathematical modeling of the operation of the proposed technical support for the treatment of waste heap reclamation in comparison with the opposed analog proves the ecological and economic efficiency of the eco-adaptive soil reclamator. The average value of profit ratios, when using the proposed soil reclamator, is 121.82 % higher than with the involvement of opposed equipment. Indicators of the negative environmental impact of the designed equipment are 100 % lower than the environmental impact when operating the analog. The proposed technical solution can be effectively applied both in schemes of sanitary cleaning of settlements, and in the process of modernization of agricultural machinery

Authors: Al-Hasani Noor R. , Royall Paul G. , Rayment Neil , Wolff Kim 
Published: September 2022

The aim: to evaluate combined microscopy techniques for determining the morphological and optical properties of methadone hydrochloride (MDN) crystals.
Materials and methods: MDN crystal formation was optimized using a closed container method and crystals were characterized using polarized light microscope (PLM), scanning electron microscopy (SEM) and confocal microscopy (CM). SEM and CM were used to determine MDN crystal thickness and study its relationship with crystal retardation colours using the Michel-Levy Birefringence approach.
Results: Dimensions (mean±SD) of diamond shaped MDN crystals were confirmed using SEM and CM. Crystals were 46.4±15.2 Vs 32.0±8.3 µm long, 28.03±8.2 Vs 20.85±5.5 µm wide, and 6.62±2.9 Vs 9.6±4.6 µm thick, respectively. There were significant differences between SEM and CM thickness measurements (U=1283, p<0.05), as the SEM exhibited thinner diamond crystals. The combined use of PLM and Michel-Levy chart enabled the observation of a predominantly yellow coloured MDN crystal, mean thickness at (428 nm) mean retardation value.
Conclusion: The SEM was superior and successfully determined MDN crystal dimensions for the first time, whilst the CM results were affected by the Rhodamine dye staining process used for visualisation. The qualitative analysis of the crystallinity status of methadone hydrochloride optimally achieved using a combination of PLM and SEM techniques

Metal yüzeyleri korozyonun etkisinden korumak için organik kaplamalar yaygın olarak kullanılır. Organik kaplamalar ile korozyon korumasının mekanizmaları bilinmesine rağmen, bu mekanizmaların gelişiminin tuzlu sis (ASTM B-117) ve yoğuşma kabini (ASTM D4585) gibi geleneksel hızlandırılmış maruziyet testleri ile izlenmesi mümkün değildir. Bu testlerde korozyon sadece görsel emarelerin ortaya çıkmasıyla gözlenebilir, bu durum kaplama altında korozyon başlangıcından çok sonra gerçekleşebilir ve dolayısıyla numuneler arasında farkların ortaya çıkması için uzun test sürelerine ihtiyaç duyulabilir.
Bu çalışmada bir organik kaplamanın iki farklı hızlandırılmış maruziyet testi etkisi altında yıpranması takip edilmiştir. Farklı sürelerde maruziyet görmüş numunelerin elektriksel empedans spektrumlarının ölçülmesi ve uygun eşdeğer elektriksel devreler ile modellenmesi kaplama altında meydana gelen yıpranmayı göstermiştir. Görsel inceleme ile herhangi bir korozyon etkisi görülmese de, EIS ile 60 saat tuzlu sis testinde korozyon başlangıcı gözlemlenmiştir, ancak 240 saat yoğuşma kabini korozyon başlangıcı için yeterli olmamıştır. Sonuçlar test edilen kaplama sistemi için tuzlu sis testinin, yoğuşma testine göre çok daha fazla yıpranma meydana getirdiğini göstermiştir.

But as soon as the object is used for its intended purpose, its technical resource begins to be consumed. Early diagnostics and condition detection are important for reliable and safe operation of technical facilities. The results of early diagnostics are used both for prevention of emergency situations and for operation of technical objects according to their condition. In this article, the task is to analyze the methods and algorithms of data mining used in the tasks of determining and predicting the state of technical objects. Neural networks, decision trees, growing pyramid networks, metric algorithms, and the support vector method are considered. Advantages and disadvantages of data mining methods and algorithms are given. Special attention is paid to algorithms and methods for identifying informative features in empirical data, in particular, filtering, projection, and wrapping methods. The use of these methods and algorithms is important to simplify the models used to classify the States of technical objects and improve the accuracy of diagnostics. Analysis of the world scientific literature has shown the relevance of using methods and algorithms for data mining in integration with methods for identifying informative features. These methods are usually used in conjunction with wrapper methods and filters to improve diagnostic accuracy and condition detection of technical objects.
