Authors: TÜZÜN Elif , KARAKUŞ Selcan
Published: November 2020

We investigated the ultrasound-assisted adsorption of Basic Blue 41 (BB41) dye from aqueous solutions using a green and low-cost adsorbent such as a Salda mud (SM) in our study. BET, FTIR, and SEM techniques were used to determine the morphology and the functional groups of SM before and after dye adsorption. Furthermore, we calculated different adsorption kinetic, isotherm, and error models (SSE, HYBRID, and ARE) parameters to evaluate the optimum experimental conditions such as the initial dye concentration of BB41 (6.25-50 ppm), SM dose (0.05–0.2 g), pH (3–10), and sonication time (400-3600 s). The value of uptake (%) of SM for BB41 was %94 at 50 ppm,25 °C at 3600 s. Following this, we found that the pseudo second-order (Type2) model of BB41 was the best fitted model with highest R2 (0.973-0.999) values. We developed a simple, low-cost, and fast to remove BM41 from water using natural and efficient SM adsorbent, which exhibited superior adsorption performance in wastewater treatment under ultrasonic irradiation.
Calculation of the Cutting Forces and Torque when Milling with End Mills
Authors: Grubyi S.V.
Published: November 2020

This paper presents a computational sequence for calculating the components of the cutting force and torque when milling with carbide end mills. The calculation algorithm includes the transition from the tangential and radial components of the force to the force components in the machine coordinate system. On the helical cutting edge, two parts are highlighted: one on the cylindrical (peripheral) surface and the other one on the arc of the rounded tip of the tooth. These parts of the cutting edge are divided into sections where the calculation is performed, followed by summation of the force components along the axes of the machine co-ordinate system and the moment relative to the axis of the cutter. An analysis of the components of the force and torque depending on the depth of cutting, feed, number of teeth of the cutter, blade wear and radius of the tip rounding is performed. The ratio of forces and moments for various milling conditions of structural carbon steel and aluminum alloys is shown. The developed algorithm is applied in a computational program that can be used to perform operational calculations of forces and torque for various milling conditions. The calculated parameters can be used as technological limiters in optimization problems, as well as for strength calculations of tools, milling equipment, and the selection of components of milling machine drives.
A Study of Parameters of the Sewing Thread Cutting Process
Authors: Krasner S.Y. , Novikov Y.V.
Published: November 2020

Sewing thread cutting processes are widely used in semi-automatic machines in the garment industry. The lack of scientifically justified methods for designing mechanisms for thread trimming in semi-automatic sewing machines makes studying these processes a topical issue. There are works that examine cutting free-hanging yarn using scissors. However, these results cannot be used to develop mechanisms for thread trimming in semi-automatic sewing machines for the following reasons: the properties of free-hanging yarn and sewing thread vary significantly, and the cutting conditions for the thread that grips the blade of a movable knife are different as well. Another reason is that as a rule, sewing thread cutting occurs in a limited space, which imposes a significant restriction on the design parameters of knives and affects the cutting process. There are no such restrictions when cutting yarn. Cutting threads by the method of scissors does not provide complete cutting of all the components of the thread if the knife blades are not in tight contact with each other. To ensure complete trimming, a design scheme of cutting was developed, and calculation formulas were obtained for determining the force exerted by the thread on the movable knife, taking into account the mechanical characteristics of the cut thread.
Surface Friction-Electric Treatment of Aluminum Alloys
Authors: Edigarov V.R.
Published: November 2020

This paper examines a combined friction-electric treatment of surface layers of machine parts made of aluminums alloys. The temperature released during the friction process is the main technological factor of the treatment, and the heat released during the passage of electric current through the local volume of friction-thermal action is an additional heat source. The paper presents the results of studying a surface modification method involving friction-electric treatment of aluminium alloys with reinforcement by aluminium oxide particles under varied technological conditions: density of electric current, pressing force of the tool, shape of the tool working zone and speed of treatment. A hard alloy tool with high temperature resistance was used as a tool for friction-electric treatment. The tool was installed in a mandrel of a special design allowing supply of a modifier representing a mixture of aluminum oxide particles with a surfactant to the treatment zone. Using the friction-electric treatment of the surface layer of samples with reinforcement by aluminum oxide particles it was possible to increase the surface hardness by about 30–40 % and thickness of the hardened layer by 3–5 times due to the local deformation and passage of electric current through the treatment zone, and to improve wear resistance of the surface layer.
The Influence of the Interference Effects on the Aerodynamic Characteristics of the Reentry Vehicle and Its Parachute System Structural Elements During Their Separation
Authors: Kalugin V.T. , Lutsenko A.Y. , Slobodyanyuk D.M.
Published: November 2020

This work considers the aerodynamic characteristics of the reentry vehicle (RV) of a segmental-conical shape, and the parachute container hatch cover (PCHC) during its separation. Due to the aerodynamic interference, the hatch may collide with the RV. The authors propose a method of studying the aerodynamic characteristics of the PCHC and RV based on modelling using the dynamic mesh technology in the FlowVision software package. Stationary flow around the RV until the hatch cover separation, flow around the hatch cover and free flow are calculated. As the result of the calculations, the PCHC trajectories (excluding gravitational forces) under various initial separation conditions, as well as the aerodynamic characteristics of the RV are obtained. The cases when the hatch cover collides with the RV are identified.
An Analysis of the Efficiency of Electric Propulsion Engines for Maintaining a Low Orbit of Small Spacecraft
Authors: Volotsuev V.V. , Salmin V.V.
Published: November 2020

This paper examines the problem of maintaining the plane parameters of the working orbit of a small spacecraft using an electric propulsion engine. In low working orbits, due to the Earth’s atmosphere, a spacecraft is subjected to aerodynamic drag forces, which results in a decrease in the radius of the orbit and a potential termination of the useful target functioning. The time parameters of the cyclogram for maintaining the working orbit of a small spacecraft with an electric low thrust engine are analyzed taking into account the variability of the atmospheric density. The cyclogram consists of sections of the passive and active movement under the action of the low thrust engine. For the satellite under study, suitable thrust parameters of the electric engine are selected, which allow the correction of the plane parameters of the low orbit. Using the characteristics of the thrust and specific impulse of the electric jet engine, fuel reserves for correction over a long period of time are calculated. The results of the analysis confirm the effectiveness of the electric propulsion engine in terms of fuel consumption for correction.
Numerical and physical modeling of bar deformation under axial loading in the channel. Part 1
Authors: Ovchinnikov N.T. , Sorokin F.D.
Published: November 2020

In two parts of the work, numerical and physical modeling of the deformation of the bar in the channel under axial compression is carried out. The regularities of nonlinear bending of the bar in the plane are revealed. Bar shapes are determined by the load history and can differ at the same force value. The solution is to find the shape with the lowest potential energy. The first part of the work describes the numerical model of the bar and the results of its application. The shapes of the bar bending under gradual loading are obtained, the studies coinciding with V.I. Feodosev’s analytical solution. Further research shows that the solution to the problem has a more complex ramified structure with various additional shapes. Deformation of the bar under gradual loading occurs in the form of a sequential variant appearance of bending waves in the bar under forces determined by the degree of non-uniformity of the lengths of potentially unstable sections and forming a range of shape instability. In variant transitions from one initial shape with a loss of stability, it is possible to obtain various subsequent shapes that differ in the sequence of deformation of the sections with one number of half-waves, or the number of generated half-waves. When a straight bar is loaded in one step, an increase in the force leads to a sequential increase in the number of bending half-waves in the corresponding ranges of the existence of shapes. The results obtained can be applied to the analysis of the operation of such bar objects as drill, casing, tubing strings in the well and cased pipelines, pipelines in the well and tunnel.

Authors: Bolshikh A.A. , Eremin V.P.
Published: November 2020

The paper describes current trends in the design of load-bearing structural elements of modern airliners made using polymer composite materials. In modern passenger airliners, polymer composite materials are used to ensure mass perfection of both lightly loaded elements and critical units, including wing and fin boxes. By means of the finite element method, a box model was created using shell finite elements. Parametric optimization was carried out with account for the anisotropic properties of structural materials. The purpose of the work is to develop a methodology for calculating the structural strength elements of the box and justify the required thicknesses with restrictions on compressive / tensile deformations and loss of stability. The developed methodology makes it possible to obtain a box structure with a minimum mass, while maintaining the necessary stiffness and strength characteristics at the stage of preliminary design.

Authors: Evdokimov R.A. , Tugaenko V.Yu. , Smirnov A.V.
Published: November 2020

The study introduces a method for determining the characteristics of long-period oscillations of the International Space Station structure by analyzing the displacement of the sighting axis of scientific equipment relative to the calculated position when observing the Earth’s surface from the Russian segment. The technique makes it possible to identify long-term oscillations through noise caused by high-frequency oscillations and measurement errors, as well as long-term trends associated with a change in the orientation of the station. The work was carried out as part of the first stage of the Pelican space experi-ment to develop the technology of wireless energy transmission in space. After processing the measurement results performed in the experiment sessions, it was possible to determine the maximum values of the amplitudes and angular velocities of the displacement of the sighting axis in order to clarify the requirements for the guidance system of scientific equipment used in the subsequent stages of the experiment.

X-ray image based pneumonia classification using convolutional neural networks
Authors: AlSumairi Sarah Badr , Ismail Mohamed Maher Ben
Published: November 2020

Pneumonia is an infectious disease of the lungs. About one third to one half of pneumonia cases are caused by bacteria. Early diagnosis is a critical factor for a successful treatment process. Typically, the disease can be diagnosed by a radiologist using chest X-ray images. In fact, chest X-rays are currently the best available method for diagnosing pneumonia. However, the recognition of pneumonia symptoms is a challenging task that relies on the availability of expert radiologists. Such “human” diagnosis can be inaccurate and subjective due to lack of clarity and erroneous decision. Moreover, the error can increase more if the physician is requested to analyze tens of X-rays within a short period of time. Therefore, Computer-Aided Diagnosis (CAD) systems were introduced to support and assist physicians and make their efforts more productive. In this paper, we investigate, design, implement and assess customized Convolutional Neural Networks to overcome the image-based Pneumonia classification problem. Namely, ResNet-50 and DenseNet-161 models were inherited to design customized deep network architecture and improve the overall pneumonia classification accuracy. Moreover, data augmentation was deployed and associated with standard datasets to assess the proposed models. Besides, standard performance measures were used to validate and evaluate the proposed system.

Published: November 2020

In recent years, handwritten character recognition has become an active research field. In particular, digitalization has triggered the interest of researchers from various computing disciplines to address several handwriting related challenges. Despite these efforts, there are still opportunities for the development and improvement of the recognition of the handwritten Arabic letters. In this paper, we designed and developed a deep ensemble architecture in which ResNet-18 architecture is exploited to model and classify character images. Specifically, we adapted ResNet-18 by adding a dropout layer after all convolutional layer and integrated it in multiple ensemble models to automatically recognize isolated handwritten Arabic characters. A standard Arabic Handwritten Character Dataset (AHCD) was used in the experiments to train and assess all the proposed models. Satisfactory results were obtained using all models. The best-attained accuracy was 98.30% using a typical ResNet-18 model. Similarly, 98.00% and 98.03% accuracies were obtained using an ensemble model with one fully connected layer (1 FC) and an ensemble with two fully connected layers (2 FC) coupled with a dropout layer, respectively.

Authors: Mesquita Amir Z. , Felippe Adriano de A. M. , Lage Aldo M. F. , Ribeiro Patrícia A. M.
Published: November 2020

Nuclear Technology Development Center (CDTN) offers the Training Course for Research Reactor Operator (Ctorp). This course is offered since 1974 and about 250 nuclear professionals were certificated by CDTN. Thus, a digital simulation system for the IPR-R1 Triga research reactor was developed to be a tool for teaching, training and recycling professionals. The simulator was developed using the LabVIEW® (Laboratory Virtual Instruments Engineering Workbench), with support calculation software, where mathematical models and graphical interface configurations form a friendly platform, which allows the trainee to be identified with the physical systems of the research reactor. A simplified modeling of the main physical phenomena related to the operation of the reactor and the reactivity control systems, reactor cooling and reactor protection was used. The digital simulator allows an HMI (Human-Machine Interaction) by manipulating system variables and monitoring trends in quantities during the operation of the reactor, showing an interactive tool for teaching, training and recycling for professionals in the IPR-R1 Triga nuclear research, allowing simulations of the start, power and stop operations. This paper presents the design and results of the user visual interfaces developed for the reactor operation simulator. This is the equivalent part of structured text programming and, therefore, the most significant part of the developed simulator.

Authors: Martins Ana , Castro Lurdes , Fragata Isabel
Published: November 2020

Introdução: A lesão renal aguda é uma complicação frequente após implantação percutânea de válvula aórtica com impacto na morbimortalidade dos doentes. É importante identificar fatores de risco modificáveis para desenvolver estratégias preventivas. Pretendeu-se determinar a incidência, fatores de risco e morbimortalidade a 30 dias e um ano relacionada com a ocorrência desta complicação em doentes submetidos a implantação percutânea de válvula aórtica.Material e Métodos: Estudo retrospetivo em 149 doentes consecutivos submetidos a implantação percutânea de válvula aórtica no Hospital de Santa Marta. Os dados foram colhidos a partir dos registos periprocedimento, e estratificados pela existência de lesão renal aguda de acordo com a classificação AKIN.Resultados: Um total de 149 doentes, 43,0% sexo masculino com mediana de idade 82,00 [77,50 – 85,00] anos foram incluídos no estudo. A incidência de lesão renal aguda foi de 14,8% (n = 22). O sexo feminino (OR 0,138, IC 95%; 0,022 – 0,854; p = 0,033) apresentou maior risco desta complicação. Os doentes com lesão renal aguda tiveram internamentos mais prolongados (OR 1,043, IC 95%; 1,001 – 1,085; p = 0,043); a mesma está associada ao aumento da mortalidade aos 30 dias (OR 13,889, IC 95%; 2,371 – 81,363; p = 0,004).Discussão: O desenvolvimento de lesão renal aguda relaciona-se com variáveis pré-operatórias e é determinante da morbimortalidade. No entanto, o caráter retrospetivo e a reduzida dimensão da população estudada limitaram a capacidade de identificação e determinação do peso de cada um dos fatores.Conclusão: A lesão renal aguda é uma complicação da colocação percutânea de prótese aórtica com grande impacto na morbimortalidade, justificando a importância da sua prevenção.

Published: November 2020

Introduction: Lower limb amputees present a high risk of falling. This study aims to characterise fall history in unilateral lower limb amputees that are autonomous in the community, identifying differences between transfemoral and transtibial amputees and assessing fear of falling between fallers and non-fallers.Material and Methods: Descriptive, cross-sectional study of consecutive community-dwelling unilateral lower limb adult amputees of any aetiology, attending outpatient consultation in a Portuguese Physical and Rehabilitation Medicine central and university hospital department. Inclusion criteria: a prior 12 week individualised rehabilitation program for prosthesis training; regular prosthesis use for more than one year with autonomous gait; and a Functional Independence Measure® score equal to or greater than 100. Injury severity was classified according to the National Database of Nursing Quality Indicators® injury falls measure. In order to assess walking performance over short distances and fear of falling we used the 10-meter walk test and the Falls Efficacy Scale, respectively.Results: In a sample of 52 lower limb amputees, mainly men (80.8%) and of traumatic aetiology (63.5%), with a mean age of 57.21 ± 11.55 years, 36.5% reported at least one fall in the previous 12 months, all classified as minor injuries. Transfemoral amputees (n = 23) presented a higher number of falls (2.22 ± 3.23, p = 0.025) and lower gait velocity (0.77 ± 0.26 m per second, p < 0.001). Regarding fear of falling, we found no significant differences between fallers and non-fallers.Discussion: The prevalence of falls was low and of minor severity. Transfemoral amputees fell more often and were slower. There were no reported differences in fear of falling between groups.Conclusion: This paper contributes information about Portuguese lower limb amputees, whose studies are scarce and are rarely dedicated to falling.

Published: November 2020

Introdução: É ainda parca a evidência científica quanto ao entendimento que as crianças têm sobre o conceito de morte, recentemente apontado pela International Children’s Palliative Care Network como área prioritária de investigação. Em particular, a evicção da emoção nesta área de investigação é uma lacuna importante. Este estudo visa desenvolver uma visão aprofundada da dimensão emocional da compreensão da morte pela criança, procurando, também, relacioná-la com a dimensão cognitiva.Material e Métodos: Entrevistámos crianças (três a seis anos), com recurso a um livro ilustrando o cenário hipotético em que uma criança se deparava com a de morte de um familiar. Colocámos questões para avaliar os subconceitos cognitivos da morte e a dimensão emocional (o que sentiria a criança e o que lhe devia ser dito pelos pais).Resultados: Dos 54 participantes, a maioria disse que a criança se sentiria triste (n = 46, 85%) e que os pais deveriam informá-la (n = 47, 87%); estas respostas não variaram significativamente com a idade. A compreensão cognitiva do conceito de morte das crianças que referiram a tristeza foi significativamente superior.Discussão: Mesmo as crianças mais pequenas sentem a morte, não sendo possível desligar as compreensões cognitiva e emocional. Adicionalmente, as crianças devem ser informadas, com vista a uma elaboração adequada e multidimensional da morte.Conclusão: Este estudo fornece informação valiosa aos profissionais de saúde e outros adultos interessados sobre a forma como a criança em idade pré-escolar se posiciona em relação à morte.

Efficacy of Some Bacterial Biocontrol Agents as Seed Treatment against Root Knot Nematode, Meloidogyne incognita on Tomato
Authors: Nyodu Karter , Das Debanand
Published: November 2020

Pot experiment was conducted to evaluate the efficacy of two formulations (talc formulation and vermi formulation) of four bacterial nematode biocontrol agents viz., Bacillus subtilis, Bacillus pumilus, Bacillus megaterium and Pseudomonus flourescens as seed treatment against root knot nematode, Meloidogyne incognita on tomato. All the bioagents were tries at 10 and 20g / kg of seed. The experiment was terminated at 60 days after sowing the seed. The results revealed that all the treatments significantly increased the plant growth parameters and reduced the nematode multiplication over untreated control. However, maximum plant growth parameters and minimum galls per root system, eggmasses per root system, eggs per egg masses and final nematode population was recorded when seeds of tomato (var. Pusa Ruby) was treated with talc formulation of Pseudomonus flourescens @20g/kg followed by seed treatment with vermi formulation of Bacillus subtilis @ 20g/kg of seed.
Effects of contact stress on patellarfemoral joint and quadriceps force in fixed and mobile-bearing medial unicompartmental knee arthroplasty

Background Unicompartmental knee arthroplasty (UKA) is an effective treatment for end-stage, symptomatic unicompartmental osteoarthritis of the knee joint. However, patellofemoral joint degeneration is a contraindication to medial UKA. Therefore, the objective of this study was to evaluate the biomechanical effect of medial UKA using fixed-bearing (FB) and mobile-bearing (MB) design prostheses on the patellofemoral joint. Methods A three-dimensional finite-element model of a normal knee joint was developed using medical image data. We performed statistical analysis for each model. The differences in contact stress on the patellofemoral joint and the quadriceps force between the FB and MB designs were evaluated under a deep-knee-bend condition.Results At an early flexion angle, the results of contact stress showed no significant difference between the FB and MB medial UKA models and the intact model. However, at large flexion angles, we observed a significant increase in contact stress with the FB models. On the contrary, in the case of the MB models, we found no statistically significant increment compared with the intact model. Our results indicate that with medial UKA, the contact stress increased and greater quadriceps force was applied to the patellofemoral joint. However, performing UKA on a patellofemoral joint with osteoarthritis should not be difficult, unless anterior knee pain is present, because the increase in contact stress is negligible. Conclusions Our results show no significant difference in contact stress on the patellofemoral joint between the medial UKA and intact knee joint models. Such a mechanism was easily found in MB medial UKA. Therefore, this study biomechanically showed that degenerative changes in the patellofemoral joint should not be considered an absolute contraindication to treatment with medial UKA.
