THE ROLE OF PREOPERATIVE PLANNING IN INCREASING IN THE TREATMENT EFFICIENCY OF HUMERUS SHAFT FRACTURES
Authors: Kononenko S.V.
Published: April 2022

Fractures of the humeral diaphysis often cause problems traumatologists encounter in their daily practice. With the development of industrialized society, the nature of injury in patients of working age has changed: low-energy injury is replaced by high-energy one. To ensure the treatment efficiency to patients with humeral fractures, thorough preoperative planning is mandatory. It often includes additional imaging methods as Xray and computed tomography. The purpose of this study is to determine the role of preoperative planning in improving the efficiency of the treatment of humeral shaft fractures. Materials and methods. The study involved 49 patients aged from 19 to 75 years with comminuted fractures of the humeral shaft. By the age distribution, patients of working age prevailed, by the sex distribution, men dominated. In most of the cases (81.6%), there were high-energy traumas. According to the AO classification, 20.4% of fractures were assessed as type 12B, 79.6% of the traumas belonged to the type 12C. 18.4% of the patients received conservative treatment, 81.6% of the patients underwent surgical treatment. In 42.9% of cases, CT with threedimensional reconstruction was performed to provide precise anatomical information of the humeral fractures. In 61.2% of cases, in order to develop optimal tactical repositions of bone fragments, we used a scheme of typical contact relationships between bone and various tissue of the studied area of the humerus.

Results and discussion. All patients were divided into 4 groups depending on the examination methods applied and the chosen tactics of preoperative planning. The first group consisted of the patients who, for preoperative planning purposes, were performed on only standard radiographic in two projections. The second group included patients who received CT with anatomical 3D models in combination with standard radiographs. The third group consisted of patients who underwent standard radiography in combination with the schemes of typical contact relationships between bone and possible tissue. The patients in the fourth group received radiographs, computed tomography with anatomical 3D models, and an applied scheme of typical contact relationships for preoperative planning. Additional research methods, namely some anatomical 3D modelling based on the CT findings, in combination with biomechanical features of changes in bone fragments contribute to the improvement in the quality of preoperative planning, the development of the algorithm of anatomical and functional intraoperative reposition, as well as reduce the risk of iatrogenic damage to important soft tissue structures.

Published: April 2022

In recent years, the issues of "extraesophageal manifestations" of gastroesophageal reflux disease has been receiving more attention from researchers and clinicians that can be explained by the complexity in diagnosis and treatment of the disease, and the necessity in collaboration between medical professional of different specialties as extra-esophageal manifestations can come to the fore imitating diseases of other organs. In the oral cavity there is a favourable environment for the development of beneficial, pathogenic and opportunistic microorganisms. The aim of this study is to investigate the state of oral mucosa microbiotope in patients with gastroesophageal reflux disease. The study included 90 individuals aged from 25 to 55 years, the two test groups involved 30 people in each who had clinically and laboratory confirmed diagnosis of gastroaesophageal reflux disease with hyperacidity and hypoacidity; control group consisted of 30 healthy individuals. The study has demonstrated that the number of microorganisms in the oral cavity differs significantly in sick and healthy people. The most significant changes have been found on the tongue (presence of a large number of opportunistic microorganisms and pathogens) and observed in patients with gastroesophageal reflux disease, especially with high gastric juice acidity. Changes in the micro-biotope on the tongue can be used for confirming diagnosis of gastrointestinal disorders (chronic gastritis, peptic ulcer disease, duodenitis), and gastroesophageal reflux disease in particular.

Authors:   Central Ukrainian National Technical University, Kuleshkov Yuriy , Chernovol Mikhail ,   Central Ukrainian National Technical University, Rudenko Timofey
Published: April 2022

A turbocharger is a unit of modern internal combustion engines designed to boost it. Since a drive of the turbocharger is most often carried out from the energy of the exhaust gases, the conditions of its operation can not be called favorable: the temperature of the exhaust gases sometimes reaches 7000C, high chemical activity of the exhaust gases, high speed of rotation of the turbine. The consequence of difficult operating conditions is the wear of its elements. One of the main causes of wear of the active elements of the turbocharger is abrasive wear. Various methods of restoration and strengthening can be used to restore machine parts. However, not all methods can provide the necessary resource for the restoration and strengthening of parts working in abrasive and corrosive environments. One of the modern directions of increasing the wear resistance and other properties of reducing coatings is the use of composite materials. This article presents the results of research on the development of a new method for restoring and strengthening parts with composite materials based on the use of chemical vapor deposition of metals CVD - method (Chemicikal Vapor Deposition) by decomposition of organometallic compounds. It is shown that the developed composite material obtained by the CVD-method of decomposition of organometallic compounds provides an increase in wear resistance of at least 2.0...2.2 times in comparison with new parts composite material. Vapor-phase deposition of metals, Chemicikal Vapor Deposition-method, decomposition of organometallic compounds.

With the increasing proportion of the elderly population, neurodegenerative diseases such as dementia are becoming more prevalent worldwide. Vascular risk factors are considered significant targets for cognitive decline prevention. We reviewed the effect of cardiovascular risk factors on cognitive decline prevention in the elderly to evaluate the quantity and quality of evidence in managing the elderly population with cognitive decline. Data analysis was available from 25 studies that explored the effects of controlling cardiovascular risk factors on the risk of cognitive impairment. These risk factors include diabetes mellitus, high blood pressure, high cholesterol levels, and exercise and physical activity. The most positive evidence was found for exercise and physical activity. On the other hand, diabetes mellitus and cholesterol modifications showed no positive impact on cognitive function. Studies on hypertension control were incongruous. There is a need for large-sample, robust randomized clinical trials to provide sufficient evidence for the modification of various cardiovascular risk factors in preventing cognitive decline.

Background:Dyslexia is a typical learning disability that does not affect intelligence but causes problems with reading, writing, and spelling. It is influenced by certain genes, due to which several researchers have attempted to identify the susceptible gene. Dyslexia is incurable and diagnosis is difficult because it always overlaps with other learning disabilities. Hence, timely assessment and intervention consequently give the best results. Therefore, our aim was to find the relation between dyslexia and single nucleotide polymorphisms (SNPs) in several candidate genes like DYX1C1, KIAA0319, and DCDC2 in Indian population. Methods:In the present study, 103 individuals with dyslexia and 100 controls in the age group between 6 to 15 years were taken. Thirteen SNPs in the KIAA gene, seven SNPs of DCDC2, and three SNPs of the DYX1C1 gene were analysed by the Mass Array technique. Results:The association of dyslexia with SNPs rs3756821, rs6935076, rs4576240 of the KIAA gene was found significant. A significant association was found with rs600753 of the DYX1C1 gene and dyslexia and we could not find any association of the DCDC2 gene with dyslexia. Conclusions:Prerequisite genetic analysis is necessary for the diagnosis of dyslexia as it is a crucial educational barrier. Treatment is known to be most effective if dyslexia is identified in the early stages for effective intervention for children before they experience prolonged reading failure. Further, it helps in prenatal diagnosis for early intervention.

Published: April 2022

In recent years, a new direction of energy saving in small refrigeration machines has been widely studied in the world, namely the use of new classes of substances as a working fluid. Studies of the thermophysical properties of colloidal solutions of nanoparticles with oils and refrigerants show the high prospects for the use of this class of substances in refrigeration. Therefore, the task of studying heat exchangers operating as part of small refrigeration machines on nanofluids seems relevant. The article provides information on the prospects for the use of nanoparticles in heat exchangers of a re-frigeration machine running on isobutane. The influence of nano impurities is considered in the ex-ample of theoretical and experimental study of the capacitor. At the same time, modern studies of the influence of nanofluids on the heat exchange characteristics of heat exchangers of refrigeration ma-chines were taken into account. Experimental study of a small refrigeration machine running on iso-butane with nanoparticle impurities was performed on a calorimetric stand, which allows the machine to operate in a wide range of modes with support for specified cycle parameters and high-precision determination of the key performance of all elements of the refrigerator, including compressors and heat exchangers. The study showed the high prospects for the use in small refrigeration machines of condensers such as "pipe in a pipe" and the possibility of significantly improving their heat transfer characteristics through the use of nanofluids as a refrigerant. The results show an increase in the heat transfer coefficient in the condenser by 4.5-16 %.

The study of heat transfer during condensation in the middle of the pipes is relevant due to the constant need to improve the design of various heat exchangers (condensers of refrigeration and air conditioning systems, reactor safety systems, and power plant heaters). It is important to know the exact values of heat transfer coefficients in the case of condensation when their value is close to the heat transfer from the cooling side. Well-known theoretical, semi-empirical and experimental models and correlations for heat transfer calculation during condensation of working fluids inside smooth horizontal pipes have been described in the article. Selected models are widely used in various scien-tific publications for heat transfer prediction and construction of various heat exchangers with in-tube condensation. All correlations allow determining the average by tube perimeter, but local by the length of the tube, heat transfer coefficients in the case of annular and intermediate regimes of two-phase flow. All used dependences take into account current modes of phase flow. For choosing the best correlations, a comparison between selected models and experimental values of heat transfer coefficients obtained by different authors for condensation of ten working fluids inside smooth hori-zontal tubes with internal diameters more than 3 mm have been performed. Experimental values were selected from well-known works, in which heat transfer was studied during condensation of such fluids as fluorocarbons, immersion refrigerants, hydrocarbons and steam in the case of intermediate and annular phase flows with a detailed description of research conditions (geometrical parameters of investigated tubes and regimes parameters of condensation process, such as heat flux, mass velocity, vapour quality, and condensation temperature). Comparison of various models with experimental data of different authors allowed identifying the models that show the best convergence with experi-ments among all correlations. Recommendations (range of application) for use of models in engineer-ing practice are given.

Algorithmic and software developments are highlighted that provide a full cycle of processing the information parliaments of electric motors, from the transformation of a physical quantity into a unified signal, to data visualization. The structure of microcontrollers, which were used in the development of the measuring system, is investigated. In particular, the performance of the ESP8266 microcontroller, which was used to transfer data received from measuring sensors to a server application. The method of visualization of the obtained data using web-server technologies is highlighted. The proposed system was tested using a DC electric motor of the RS-775 series. The error of the measuring sensors used in the proposed system is determined by calculating the sample standard deviation from the expected results. Particular attention is paid to the development of server software in terms of processing signal parameters and visualizing its changes, the possibility of archiving arrays of received data, the possibility of changing the operating modes of the electric motor and ways of displaying information. The performance characteristics of a prototype device for measuring the torque of an electric motor based on an inductive sensor used as part of the proposed measuring system have been studied. The article presents the possibilities of using an information-measuring system in combination with additional measuring devices that can be connected to it using a local network, thus forming a distributed sensor network of measuring devices interconnected via a radio channel. The expediency of building such networks for remote objects, where unified (WI-FI, WI-MAX, GSM) data transmission technologies can be used, is substantiated.

Sparse and Incomplete Signal Dictionaries for Reconstruction of MR Images
Authors: M Devendrappa Deepak , Pilani Karthik , N Ananth Deepak
Published: April 2022

Compressed Sensing(CS) is a mathematical approach for data acquisition in which the signals are compressible and sparse w.r.t. to an orthonormal basis. These sparse signals are reconstructed from very less measurements. CS technique Is widely used in Magnetic Resonance Imaging (MRI) where the doctors suggest the patients to undergo MRI scans for diagnosing their body parts. During the prolonged MRI Scan, the exact slice of the MRI cannot be achieved due to the difficulties faced by the patient or irregular changes in the body position of the patient. The idea is to reduce the exposure time of the patient’s body against the MRI scan by considering only fewer samples. Is it possible to Reconstruct the signal by making use of a fewer number of samples that are less than the Nyquist rate? Yes, it is possible to reconstruct the signal by making use of the Compressed Sensing or sampling Technique. Compressed sensing is a new framework for signal acquisition and representation in a compressible manner less below the Nyquist sampling rate. In this article, Sampling and reconstruction are dealt here thoroughly as part of the research activity. Compressive Sensing Matching pursuit (CoSaMP) is a novel technique for optimization. It is an iterative approximation method for sparse and incomplete signal recovery. CoSaMP method along with Different transform techniques is used for reconstruction. The FFT_CoSaMP, DCT_CoSaMP and DWT_CoSaMP are proposed methods for MR Image Reconstruction, where DWT-based CoSaMP along with different wavelet families give the best results when compared to other CS-based techniques w.r.t. PSNR, SSIM and RMSE analysis.

Published: April 2022

This work presents an internet of things (IoT) based building management system (BMS) for monitoring, control, and energy management in buildings to provide an efficient way of energy utilization. Existing systems mainly provide monitoring of different parameters with limited controlling/automation functions. Existing solutions also do not provide automatic decision-making, advanced safety management, and resource tracking. However, the proposed system provides a comprehensive way of monitoring, controlling, and automatic decision making regarding different environmental and electrical parameters in buildings, i.e., temperature, humidity, dust, volt, etc., by using a low-cost wireless sensor network (WSN). The architecture of the proposed system consists of five layers and uses analog sensors which are connected to Arduino Mega 2560 microcontrollers for data collecting, NodeMCUs ESP8266 for wireless communication, Raspberry Pi4 microcomputers for decision making, and nod-RED dashboard which runs locally on a Raspberry Pi 4to provide a friendly end-user interface. The system also uses the Message Queuing Telemetry Transport (MQTT) communication protocol through Wi-Fi and completely relies on the local devices in the architecture and does not need cloud computing services. The proposed system provides two different kinds of automation, i.e., safety automation for the safety of different devices with advanced features, and energy automation. The proposed system is also able to provide humidity control inside a room and to track and count the available resources in any facility. The proposed system is low cost, scalable, and can be used in any building. Simulation results show that the proposed system is highly efficient.
Optimization Algorithms based compensation of mismatches in Time interleaved Analog to Digital Converters
Authors: Naga Chakravarthi Manepalli Venkata , Bhuma Chandramohan
Published: April 2022

Time interleaved analog to digital converters (TIADCs) play a significant role in signal processing wherever higher sampling rates are required. However, TIADCs suffer from various mismatches like sampling time, dc offset, gain, bandwidth etc. This results in generation of erroneous signal. Numerous methods were proposed for estimation of these mismatches and for correction of the erroneous signal. Optimization algorithms like genetic algorithm (GA), differential evolution (DE) algorithm were also used for estimation of mismatches. An overview of these algorithms and their performance comparison, with respect to various signal quality metrics like signal to noise ratio (SNR), signal to noise, distortion ratio (SNDR) etc, is given in this article.

Published: April 2022

This paper conducts a comprehensive review and comparative analysis of the research on register published in Chinese and international authoritative journals from 2010 to 2021 by employing CiteSpace 5.8.R3, a visual bibliometric software. It describes the number of publications, the keywords with the strongest citation bursts, research institutions, journals and influential authors, and pinpoints the principal frontiers of register. The results indicate that the number of publications of Chinese register research has shown a significant downward trend on the whole, while international register research has shown a significant upward trend on the whole. The journal of high-cited papers on register studies in China has a low impact factor, while international hot papers on register studies have a high impact factor. Chinese scholars focus on the different research perspectives of the register (systemic functional linguistics, multidimensional analysis and corpus), while international research pays attention to register variation, especially English variation and Spanish variation, and register in academic writing. Influential scholars leading the trend of register research include Biber and Rooy. The findings of this study would provide some academic and pedagogical implications on the register for Chinese scholars.

Published: April 2022

In this qualitative cross-case study, we examine the role of familial habitus in providing early access to navigational capital and opportunities predictive of STEM success. Interviews with 18 students with non-apparent disabilities at a large, four-year research university in New England showed that parents and family played a key role in multiple dimensions of student experiences with disability. We organized the findings around three themes about family: (a) family’s framing of disability and academic ability; (b) family support of STEM interests; and (c) family as STEM role models. We extend these findings to highlight the importance of family more broadly, supporting research that indicates the critical role that parental involvement plays in the development of STEM aspirations and success.

Published: April 2022

Addressing labor shortages within nursing and allied health professions, which have been exacerbated by the COVID-19 pandemic, requires increasing persistence and equity among community college students pursuing these fields. In this study, we adapted and combined three values-based interventions (values affirmation, goal congruence, and utility values) into one treatment, delivered via interactive text messages, with the goal to support reenrollment­ among pre-allied health students during the pandemic. Using institutional data from a statewide community college system, we randomized pre-allied health students who were enrolled in Fall 2019 and/or Spring 2020, and who had a valid mobile number on file, into treatment (n = 1,649) or control (n = 1,650) groups. Fully treated students received an average of 17 text messages over 8 weeks of Summer 2020; control students received business as usual support from the college. After adjusting for baseline differences in prior enrollment, the treatment significantly increased reenrollment by 3 percentage points (74% vs. 71%). Examination of individual differences revealed that effects were concentrated among men (+11 percentage points), Black/African American students (+7 percentage points), and students who were not enrolled in Spring 2020 (+13 percentage points). Values-based interventions, therefore, can be an important tool for addressing shortages and inequities in healthcare education and the labor force, an important step toward improving public health. Moreover, community colleges seeking to engage students who withdrew before or during the COVID-19 pandemic should leverage evidence-based practices to boost reenrollment.

Authors: Sarmiento-Moscoso Luis Santiago , Álvarez -Córdova Juan Santiago
Published: April 2022

Este artículo presentó un análisis de los principales determinantes que inciden en la diferencia salarial en el mercado laboral para el Ecuador en el año 2019, clasificando el estudio en trabajadores formales e informales. Para ello, se estimaron las diferencias salariales a través de descomposiciones econométricas, a partir de datos de la encuesta de empleo y desempleo de las cinco principales ciudades del Ecuador. La metodología aplicada se basó en técnicas de reponderación junto con estimaciones de modelos de funciones de influencia recentradas (RIF). Entre los principales hallazgos, se mostró que las diferencias salariales fueron justificadas por las características de los individuos y por la estructura productiva; además, que Guayaquil es la ciudad con mayor brecha salarial en el mercado laboral formal, mientras que, en Cuenca, las mayores diferencias salariales se registran en los trabajadores informales. Los factores claves que explican principalmente la brecha salarial son: la educación, el tamaño de la empresa y la rama de actividad. Esto evidencia la gran precariedad laboral que existe en los diferentes territorios del Ecuador, destacando la necesidad de una mayor convergencia productiva impulsada por reformas laborales que promuevan el acceso al trabajo formal y fomenten la inversión privada.Palabras clave: Diferencia salarial, desigualdad, mercado laboral, métodos de descomposición.

This article presents an analysis of the main determinants that affect the wage difference in the labor market for Ecuador in 2019, classifying the study into formal and informal workers. To carry out this study, wage differences are estimated through conometric  decompositions based on data from the employment and unemployment survey for the five main cities of Ecuador.  The applied methodology is based on reweighting techniques together with estimates of recentered influence function (RIF) models. Among the main findings, they show that the salary differences were justified by the characteristics of the individuals and by the productive structure. In addition, it is shown that Guayaquil is the city with the largest wage gap in the formal labor market, while in Cuenca, the largest differences in wage are registered in informal workers. The key factors that mainly explain the salary gap are: education, the size of the company and the branch of activity. This evidence shows the great job insecurity that exists in the different territories of Ecuador, highlighting the need for greater productive convergence driven by labor reforms that promote access to formal work and encourage private investment.Keywords: Wage difference, inequality, labor market, decomposition methods.

A suinocultura brasileira tem sido reconhecida com um dos maiores produtores mundiais, onde atualmente ocupa a quarta posição de maior produtor e exportador de carne suína. A carne suína é conhecida devido à presença principalmente de ácidos graxos poli-insaturados (PUFAs), sendo assim mais susceptível a oxidação e a rancificação, assim diminuindo o tempo de prateleira. Para minimizar essa oxidação tem se adotada a prática de incluir aditivos antioxidantes na ração, sendo os principais o ácido ascórbico (vitamina C) e o tocoferol (vitamina E). As principais ações dos antioxidantes podem ser a interceptação e diminuição do oxigênio livre, sequestrando os radicais hidroxil, quelando íons metálicos e decompondo compostos. O objetivo desta revisão é abordar sobre os antioxidantes na alimentação de suínos e seus efeitos nos produtos cárneos oriundos do processo de industrialização. A metodologia emprega nessa revisão foi um estudo descritivo, com base em artigos científicos publicados em diferentes periódicos.
