The use of hydrochloric acid in the treatment of the bottomhole formation zone leads to the significant corrosion of metals, as well as hydrogen and chloride stress cracking of pump compressor pipes. In order to solve this problem, corrosion inhibitors are added to a hydrochloric acid solution. This article presents the results of a study of the anticorrosive activity of a number of derivatives of the class of 3-alkyl-5-amino-1H-1,2,4-triazole under the conditions of hydrochloric acid corrosion of low-carbon steel. During the study, selected 3-alkyl-5-amino-1H-1,2,4-triazoles were synthesized. Their structure was confirmed and proved using NMR spectroscopy and HPLC/MS spectrometry. Regularities of the anticorrosive ction of the investigated compounds have been established using polarization electrochemical studies and gravimetric direct corrosion tests. Corrosion rates, inhibition coefficients and degrees of protection have been calculated for all inhibitors. The probable mechanism of the inhibitory action of the studied compounds has been substantiated using quantum chemical calculations based on the density functional theory using the Gaussian program. It was shown that the structure of the alkyl substituents has the greatest effect on the inhibitory activity of the studied compounds. The mechanism was proposed for the adsorption of the inhibitor, which explained the increase in protective properties with an increase in the length of the alkyl substituent. The high hydrophobicity of the aliphatic fragment, not involved in the chemisorption process, additionally prevents the acid solution from contacting the metal surface, while the heterocyclic moiety ensures the sorption of the inhibitor on the metal surface. As a result, it was shown that derivatives of the homologous series of 3-alkyl-5-aminotriazole are suitable as inhibitors of acid corrosion of ST-3 steel. The minimum length of a hydrocarbon radical at which significant inhibitory activity was observed is 7 carbon atoms. Protection degrees of 65–85% were achieved when 3-heptyl-5-amino-1H-1,2,4-triazole additives at a concentration of at least 2 g/L were added to the hydrochloric acid solution.

Published: April 2022

A study on the influence of the method for obtaining trimetallic PtCuAu/C catalysts on their activity in the oxidation of methanol has been carried out. The structural characteristics of the obtained trimetallic catalysts have been studied by X-ray diffraction and transmission electron microscopy. The nanoparticles of the material obtained by the galvanic synthesis method had a size twice as large (~ 6 nm) than the nanoparticles of the material obtained by the co-deposition of metal precursors. According to the results from the accelerated stress testing of catalysts, it was found that the material obtained by the galvanic method of substitution of copper atoms with gold had a higher residual activity in the oxidation of methanol than the commercial Pt/C analogue. This study shows the potential of obtaining and using multicomponent platinum-containing nanoparticles deposited on a carbon carrier as effective catalysts for use in methanol fuel cells.

The kinetics and mechanism of hydrogen evolution reaction on the TiSi2 electrode in x M H2SO4 + (0.5 – x) M Na2SO4 (x = 0.5; 0.35; 0.20; 0.05) solutions were studied using the methods of polarisation and impedance measurements. The cathodic polarisation curves of TiSi2 were characterised by a Tafel section with a slope of 0.116–0.120 V at E ranging from –0.30 to –0.48 V (SHE). The value of hydrogen evolution overpotential at i = 1 A/cm2 for TiSi2 was 0.90–0.96 V. The kinetic parameters of the hydrogen evolution reaction on silicide were close to the theoretical values for the slow stage of charge transfer. Based on the measurements of the differential capacitance of the TiSi2 electrode (at f = 10 kHz), depending on the cathodic polarisation and acidity of the electrolyte, it was concluded that a thin dielectric film of silicon dioxide (Si + 2H2O →SiO2 + 4H+ + 4e–) was present on the surface of the silicide. The film was not reduced with low cathodic polarisations. The impedance spectra of the TiSi2 electrode at the potentials of the Tafel region were capacitive semicircles with a misplaced centre. The impedance spectra were described by an equivalent electrical circuit, the Faraday impedance of which consisted of a series-connected charge transfer resistance R1 and a parallel R2C2 chain corresponding to the adsorption of atomic hydrogen on the electrode surface. The impedance of the double layer capacitance was modelled using the constant phase element CPE1. The χ2 criterion for the circuit was (1.3-3.7)·10-4 (when using data modulus weighting), the sum of square deviations was (1.5–4.1)·10–2, and the error in the determination of the values of circuit parameters did not exceed 10 %.The experimental values of the slopes of lg R1,E-, lg R2,E-, and lg C2,E-dependences were close to the theoretical values of the slopes for the discharge-electrochemical desorption mechanism, in which both stages were irreversible and the transfer coefficients of the stages were not equal, when the Langmuir isotherm for adsorbed atomic hydrogen was fulfilled. The reaction of absorption of hydrogen with the kinetic control proceeded at the same time as the hydrogen evolution reaction.
A model of interdiffusion occurring during the formation of thin metal films on single-crystal silicon under conditions of limited solubility of the components
Authors: Афонин Николай Николаевич , Логачева Вера Алексеевна 
Published: April 2022

Thin metal films are used in semiconductor and microelectronic devices to form ohmic and non-ohmic contacts to singlecrystal silicon. A common feature of the used Ме–Si systems is the low mutual solubility of elements and the polycrystalline nature of metal films. Solid-phase interactions during the deposition of metals on single-crystal silicon and the subsequent vacuum annealing results in the redistribution of the elements near the Me/Si interface. An important task facing the material science of solid-state electronics is to develop a mechanism of solid-phase interaction of metal thin films and single-crystal silicon. The aim of our study – was to develop a quantitative model of interdiffusion in the Ме–Si system under conditions of limited solubility of the components. The article suggests a mechanism of formation of Me–Si systems based on the diffusion and segregation of silicon near the intergrain boundaries of the metal and the limited formation of complexes during the diffusion-induced penetration of metal into silicon. The article suggests a model of reactive interdiffusion in thin metal film – single-crystal silicon systems under conditions of limited solubility of the components. Mathematical modelling was used to study the interaction of magnetron-sputtered metals Ti, W, and Nb with single-crystal silicon during isothermal vacuum annealing. The numerical analysis of experimental distributions of concentrations of Me and Si obtained by Rutherford backscattering spectroscopy allowed us to determine their individual diffusion coefficients in Me-Si systems. The model can be used for empirical studies of the redistribution of the elements of two-layer systems with limited solubility, as well as to forecast the technological conditions for the production of electronic devices.

Published: April 2022

Evolução e disseminação da Internet têm modificado comportamento de compras, especialmente, pela facilidade de acesso às informações. No Turismo, a Internet surge como parceira ideal devido à intangibilididade de produtos e serviços. Assim, o turista atual torna-se consumidor de novo mercado, conhecido como mercado virtual ou comércio eletrônico. Ademais, existem poucos estudos que consideram o comportamento de compra de serviços de hospedagem pelos residentes de Fortaleza/CE usando e-commerce, dado que, na maior parte das pesquisas científicas, Fortaleza é apresentada como destino turístico. Sendo assim, esta pesquisa analisa os fatores que influenciam o uso do comércio eletrônico na compra de serviços de hospedagem pelos residentes de Fortaleza/CE. Na consecução desse objetivo, utilizaram-se os construtos “Influência Social” e “Relevância do Preço” (UTAUT2), além dos fatores “Confiança” e “Risco Percebido” (SLADE et al., 2015). Para traçar o perfil do consumidor foram consideradas os fatores demográficos idade, nível de renda e escolaridade. Foi realizada uma pesquisa descritiva e quantitativa e a coleta de dados foi realizada pela aplicação de questionário eletrônico (Survey on-line) em uma amostra de 195 residentes de Fortaleza/CE. Na análise dos dados utilizou-se estatísticas descritivas, análise fatorial exploratória, teste exato de Fisher e, por fim, a análise de regressão linear múltipla. Resultados apontam que a influência social e o preço são os construtos que mais impactam no uso do comércio eletrônico na reserva on-line. A pesquisa demonstrou: 1) confiança não possui relação significativa com compra de serviços de hospedagem por meio eletrônico; 2) qual o perfil dos consumidores residentes em Fortaleza que fazem reservas on-line; 3) quais fatores influenciam ou não nesse uso, contribuindo para que plataformas digitais conheçam o mercado consumidor dos moradores de Fortaleza/CE relacionado à compra de hospedagem.

Published: April 2022

Objective: Early repolarization (ER) is a common finding in cases. It can be benign or malignant. We aimed to evaluate the effects of early repolarization morphology and electrocardiogram (ECG) findings on the clinic, prognosis, and mortality with angiography findings.
Method: This retrospective study included 442 patients who were admitted to the emergency department between January 2010 and December 2015 and had ER in their ECG. The patients were divided into two groups according to the horizontal and ascending ER morphology. According to the derivation, four groups were formed as inferior, inferolateral, anterior, and common. Besides, four groups were determined according to the angiography findings: left anterior descending (LAD), circumflex (Cx), right coronary artery (RCA), and normal.
Results: The average age of the patients in the study was 52.16±9.07 years and 260(58.8%) were male. Horizontal morphology was observed in 123(28%) of the patients and ascending morphology in 319(72%). Mortality was detected in 9(7.3%) of the horizontal group and 6(1.9%) of the ascending group (p=0.008). In the angiography results of the mortality group, 8(53.3%) patients had Cx, 4(26.7%) patients had RCA and 3(20%) patients had LAD occlusion. Angiography results of 318(74.5%) surviving patients were normal (p=0.001). Mortality; It had a strong positive correlation with family history, Brugada Syndrome, aVR ST-segment formation and the presence of syncope, and moderate positive correlation with gender, notch presence, QRS morphology in V1-2, and angiography results.
Conclusions: Early repolarization morphology may be a helpful finding for prognosis, mortality, and interventional angiography decisions.

Published: April 2022

Since its implementation in 2004, the Canadian English Language Benchmark Assessment for Nurses (CELBAN) has been accepted as evidence of language ability for licensure of internationally educated nurses (IENs) in Canada. This article focuses on the complexities of sustaining an occupation-specific assessment over time. The authors reference the seminal work of Epp and Lewis, who developed the original CELBAN test forms and aligned the test results with the Canadian Language Benchmarks (CLB), and then go on to describe a research and development project that was carried out under the direction of Touchstone Institute and overseen by the Centre for Canadian Language Benchmarks (CCLB) to renew the test model and develop additional content. This is followed by a discussion of the maintenance strategies required to sustain a secure assessment within the evolving Canadian context.

Exploring the Impact and Acceptance of Wearable Sensor Technology for Pre- and Postoperative Rehabilitation in Knee Replacement Patients
Authors: Cooper D.M. , Bhuskute N. , Walsh G. 
Published: April 2022

Background:
Knee replacement operations are common, highly successful procedures that are increasing in frequency. The COVID-19 pandemic has emphasized the need for innovative care pathways that reduce face-to-face appointments. We report on the impact of introducing a wearable sensor for pre- and postoperative rehabilitation of 21 knee replacement patients at 2 hospitals in the U.K.

Methods:
The sensor (BPMpathway; 270 Vision) was provided during joint school prior to knee replacement and stayed with the patient until a maximum of 9 weeks post-surgery. Participant progress and exercise were monitored remotely, with exercise regimens altered as required. Participants and clinicians could communicate remotely via the device.

Results:
The median range of motion during the first week post-surgery was 63° (interquartile range [IQR] = 21°) and increased to 136° (IQR = 16°) by week 7. The rate of participant compliance with exercises using the device was 32.3% for thrice-daily compliance and 52.4% for once-daily compliance. The 2-way communication channel was well utilized by both participants and clinicians. We report a 35.7% reduction in face-to-face physiotherapy appointments compared with standard practice. Finally, >80% of users who completed the feedback questionnaire reported a positive experience using the device, finding it easy to understand and reporting that it motivated them to perform their exercises.

Conclusions:
The use of BPMpathway was well received, effective, and reduced face-to-face physiotherapy appointments.

Clinical Relevance:
Remote monitoring can reduce the burden to the outpatient physiotherapy service by supporting the post-COVID-19 surgical service recovery plans of the National Health Service and allowing patients to recuperate at home.
Development of a New Progressive Nonintrusive Theory to Reduce Computation Time with Particle-in-Fluid Flow Application

Published: April 2022

Summary
Solid-in-fluid flow studies and modeling approaches are categorized mainly based on the scale at which solid particles are modeled. Eulerian-Eulerian approaches treat solid at the same scale as fluid. These approaches are fast but suffer from improper physics and high dispersion effect due to averaging solid properties to upscale them to the fluid scale. Eulerian-Lagrangian methods try to solve the issue by modeling each particle individually. Modeling movement of each particle in fluid is complex, especially when modeling individual particle interaction with other particles and fluid is involved. Although such an approach is favorable due to its high accuracy in modeling solid behavior, it is computationally intensive and very time-consuming. It may take hours or even days to simulate a few seconds of a solid-in-fluid flow process when number of particles grows and goes beyond one thousand. In this paper, a theory is developed to reproduce and predict solid state variables such as location and velocity with a reasonable accuracy but at least four orders of magnitude faster. This solution uses the available information from previously finished simulations to build a progressive nonintrusive formulation based on the trajectory piecewise linearization (TPWL) theory that reproduces and predicts particles locations and velocities. Reproduction or prediction run accuracy is verified by comparing the results against a verification run and the reduction in computation time is also measured. The progressive nonintrusive formulation developed in this work is universal and is not limited to solid-in-fluid flow applications such as particle transport in wellbore or hydraulic fracture in petroleum engineering, and it can be applied to other engineering or science problems too.
