Osteonecrosis of the femoral head after COVID-19: a case series
Authors: Khamidov Obid , Ravshanov Zafar
Published: September 2022

It is known that COVID-19 has an adverse effect on various organs and systems of the human body. In the available literature, there are isolated reports regarding the development of osteonecrosis after suffering COVID-19. These papers discuss the role of commonly used corticosteroids in the treatment of COVID-19 in the development of osteonecrosis. Our article presents clinical observations of four patients with bilateral osteonecrosis of the femoral heads after treatment with COVID-19. The doses of prednisolone in three patients were 4500 mg, 735 mg and 525 mg. One patient did not receive corticosteroids. Our data showed that osteonecrosis in COVID-19 survivors developed at a shorter time compared to osteonecrosis in patients without coronavirus infection. Two out of four patients had a positive family history (myocardial infarction, hypertension, thrombosis). It is possible that hereditary vascular factors played some role in the genesis of osteonecrosis of the femoral head. Further evidence is needed to understand the development of osteonecrosis after COVID-19. Probably, the development of the disease is synergistically affected by many factors, including steroid and ischemic.

Towards a Better Understanding of Museum Visitors’ Behavior through Indoor Trajectory Analysis
Authors: Kontarinis Alexandros , Marinica Claudia , Vodislav Dan , Zeitouni Karine , Krebs Anne , Kotzinos Dimitris
Published: September 2022

Nowadays, electronic museum guides have evolved to a point that can act as navigational and informational devices in the museum context; thus they also enable the collection of large volumes of spatiotemporal visitor movement data, from which individual visitor trajectories can be extracted and analyzed.
These trajectories have individual characteristics expressed through unique semantics in each museum context (based on the museum, its exhibits and its visitors) and they are restricted in an indoor environment that provides additional constraints. This work presents the benefits, the challenges, and a direction for studying museum visitor movements through context-aware indoor trajectory modeling, mining and analysis.

Simulação do desempenho acústico de um modelo BIM a partir do esquema de dados IFC
Authors: Fengler Bárbara , Sá Karina , Rossatto Rocha Raquel , Giner José Carlos
Published: September 2022

O presente artigo tem como objetivo principal verificar a possibilidade de utilizar um modelo em Modelagem da Informação da Construção, BIM - Building Information Modeling, para estimar o desempenho acústico de uma divisória. Para a análise, foi realizado um projeto simplificado em software específico de modelagem BIM e exportado o esquema de dados Industry Foundation Classes, IFC. De posse do esquema de dados, foram extraídas todas as informações geométricas e especificações do projeto no arquivo IFC com auxílio da biblioteca IfcOpenShell em Python. Com os dados extraídos, foram realizados os cálculos para determinação do desempenho acústico com Análise Estatística Energética (SEA) em software de processamento de sinais. Para fins de comparação, foi realizada a simulação de desempenho acústico do mesmo projeto no software comercial SONArchitect ISO, seguindo os procedimentos usuais de simulação. As propriedades dos materiais consideradas tanto no cálculo por SEA quanto na simulação pelo software comercial foram as mesmas. Foi definido o parâmetro DnT,w para análise por ser requisito da norma de desempenho ABNT NBR 15575:2013. Apesar das limitações dos cálculos de desempenho acústico por SEA verificadas e da complexidade para extração das informações necessárias do IFC, foram obtidos resultados de DnT,w próximos, sendo entretanto notável uma divergência maior em baixas frequências, estando de acordo com estudos anteriores. Dessa forma, conclui-se que o objetivo principal do presente estudo foi alcançado, uma vez que mostra ser possível a realização de simulações de desempenho acústico com um modelo BIM.

Published: September 2022

Debido a la importancia que contrae el comportamiento organizacional representando un eje dinamizador para la eficiencia en una empresa, es necesario considerar la forma en la cual se desarrollan los individuos dentro del área de trabajo, puede ser favorable o no favorable según la situación en la que se maneje el caso. Por consiguiente, el objetivo de la investigación es analizar el impacto que tiene el comportamiento de los colaboradores internos dentro de las organizaciones a fin de convertirse en una llave maestra para alcanzar un liderazgo eficaz. La metodología aplicada es de carácter descriptiva, en la cual se recolecta información mediante datos bibliográficos para brindar interpretación del comportamiento de las personas en sus ambientes de trabajo a través del método analítico. Se encuentra que las entidades a fin de seguir siendo competitivas recurren a medidas para reducir sus costos mediante reingeniería en sus procesos y despidos de personal, lo cual impacta en la mente de los colaboradores al caer en un ambiente de incertidumbre quitando el sentido de pertenencia de los miembros de la organización. Finalmente se concluye que mayor responsabilidad recae sobre los altos mandos, al tener como deber implementar métodos orientados a los pensamientos y forma de actuar de los trabajadores, los cuales aporten positivamente al ambiente organizacional para hacer sentir realizados a los colaboradores internos.

Debt and Emotional Labour in Present Day Serbia
Authors: Mitrovic Marijana
Published: September 2022

This article deals with the affective aspects of indebtedness in present-day Serbia. Based on ethnographic fieldwork conducted in Belgrade and Šabac during the period 2016-19, it analyses gendered aspects of affective states created and triggered by indebtedness. Indebtedness is here conceptualized to involve not just material and financial obligation, but also asymmetry in emotional labour. That way, the article contributes to the line of research that challenges understandings of debt as a binary relationship between creditor and debtor and argues for a perspective that encompasses the complex affective involvements of indebted subjects and the imbrication of indebtedness, emotional labour, love and care in the everyday life. The ethnographic fieldwork setting is kafana, a tavern with the live neofolk music, which is a space for reflection, expression or venting of the affects, but primarily for their modification, and therefore a primary site for research on postsocialist affect(s). Through the ethnographic vignettes of requesting, performing and consuming songs, as well as material obtained from the pre- and post-performance conversations with employees and customers who found themselves in different situations of debt, it analyses the affective registers of indebtedness and points out that the gendered asymmetry in care debt is formulated in the language and logic of emotional capitalism.

A Self-Similar Solution of Shock Propagation in a Mixture of Non-ideal Gas and Small Solid Particles in Magnetogasdynamics
Authors: Vishwakarma J P , Shrivastava Reena
Published: September 2022

Similarity solutions are obtained for unsteady, one-dimensional, self-similar flow of a perfectly conducting mixture of a non-ideal gas and small solid particles, behind a strong shock (cylindrical or spherical) driven by a piston moving according to power law in the presence of an azimuthal magnetic field. The small solid particles are considered as pseudo-fluid and assumed to be continuously distributed in the mixture. Effects of change in the values of parameters Kp, Ga (dust parameters), b (non-idealness parameter of the gas) and M−2A (magnetic parameter) on the shock strength, piston position and on the flowvariables in the flow-field behind the shock front are obtained. It is found that there is a decrease in the shock strength and the value of piston position due to the non-idealness of gas as well as due to the presence of dust-particles and the magnetic field. This decrease in the shock strength and the value of piston position is interpreted as a result of decrease in the compressibility of the mixture. Mutual effects of parameters are also obtained to investigate the deviations in the effects of parameters Kp, Ga and b due to the presence of magnetic field. It is observed that effects of parameters Kp, Ga and b on the shock strength and on the piston position are reduced due to the presence of magnetic field while the effects of these parameters on the flow-variables are enhanced due to the presence of magnetic-field.

Dynamic Universe Model Applications into Prediction of Blue Shifted Galaxies, VLBI Applications and other New Possible Avenues….
Authors: GUPTA SATYAVARAPU NAGA PARAMESWARA
Published: September 2022

Tensors are generally tough to understand interpret and appreciate. This is mainly because it is the number of equations that each tensor that will be subdivided into. The overall concept is difficult to comprehend. There is an additional headache, when tensors subdividing into differential and integral equations. Differential equations will not give unique solutions. Whereas Dynamic Universe Model gives a unique solution of positions, velocities and accelerations for each point mass in the system for every instant of time as its tensors subdivide into linear set of equations. This new method of Dynamic Universe Model is different from earlier mathematical methods. This can be used for solving general N-body problem. This method solved many unsolved problems earlier like Galaxy Disk formations, Missing mass in Galaxies, Pioneer anomaly, Noncollapsing Large scale mass structures, New horizons trajectory predictions etc. Now attempts to solve new problems like- 1. Mathematical Prediction of Existence of Blue shifted Galaxies 2. Explaining Very long baseline interferometry (VLBI) observations To support Dynamic Universe Model the we can find the following supporting observations 3.

Accelerating bulk viscous LRS Bianchi-II string cosmological models in S ́aez-Ballester theory of gravitation
Authors: Pradhan A , Dubey A S , Khare R K
Published: September 2022

In this paper, we obtain a spatially homogeneous and anisotropic Locally
Rotationally Symmetric Bianchi type-II string cosmological model of the universe for bulk viscous fluid distribution within the framework of scalar-tensor theory of gravitation proposed by S´aez and Ballester (Phys. Lett. 113:467, 1986). To prevail the deterministic solutions we consider time-dependent deceleration parameter (DP) which provides the value of scale factor as a = [sinh(αt)] 1 n , where α and n are arbitrary positive constants. This acclimates time-dependent DP representing models which generate a transition of the universe from the early decelerated phase to the recent accelerating phase. It is also observed that for 0 less than n less or equal than 1, our model is in accelerating phase but for n greator than 1, our model is evolving from decelerating phase to accelerating phase. The modified Einstein’s field equations are solved exactly and the derived model is found to be in good concordance with recent observations. Some physical and geometric properties of the models are also discussed.

NUMERICAL AND EXPERIMENTAL STUDY OF AEROSTATIC BEARINGS WITH VIRTUAL RECESSES AND MULTI-HOLE ORIFICES
Authors:   Le Quy Don Technical University, Trinh Quang Hung
Published: September 2022

Aerostatic bearings are ones which carry loads with nearly frictionless movement, thanks to external supply of pressurized air. The bearing pad and guide surfaces are kept apart and lubricated by a micrometer-thick compressed air film with a load capacity depending mainly on the pressure distribution. The flow of air through the gap complies with the Navier-Stokes equations and conservation of mass and energy. As Navier-Stokes equations are nonlinear differential equations, solving the aerostatic-bearing problem by numerical simulation using finite volume method in combination with experiments is considered to be effective and reliable. In this report, the influences of a virtual recess and multi-hole orifice on the performance of a rectangular flat aerostatic bearing were numerically analyzed using Ansys CFX solver. The results show that the presence of a virtual recess and its dimensions largely influence the bearing performance in terms of pressure distribution and load capacity. Similarly, the multi-hole orifice also has a significant effect on the enhancement of the performance of the bearing. The area of positive gauge pressure has been shown to be extended to almost entire bearing surface in both cases, which considerably improve the load capacity and stability. The effect of gas gap studied on the multi-hole orifice bearing indicates that the load capacity decreases with increasing the gas gap, being found to be in a fairly good agreement with the experiment.

SINGLE-PIXEL ENSEMBLE CORRELATION ALGORITHM FOR BOUNDARY MEASUREMENT ON AXISYMMETRIC BOATTAIL SURFACE
Authors:   Le Quy Don Technical University, Tran The Hung
Published: September 2022

Particle image velocimetry (PIV) measurement is an important technique in analyzing velocity fields. However, in traditional cross-correlation algorithm, the resolution of velocity fields is limited by the size of interrogation windows and the boundary layer was not captured well. In this study, single-pixel ensemble correlation algorithm was applied to analyze flow near the surface of an axisymmetric boattail model. The initial images data was obtained by experimental methods with the setup of PIV measurement. The results showed that the new algorithm was considerably improved resolution of flow fields near the surface and could be used to measure boundary-layer profile. Detailed characteristics of boundary-layer profile at different flow conditions were discussed. Interestingly, boundarylayer profile does not change much before the shoulder. However, the size of separation bubble on the boattail surface highly decreases with increasing Reynolds number. The study provides initial results of flow fields, which could be useful for further investigation of drag reduction by numerical and experimental techniques.

To guide an optical signal into an integrated optical circuit, small optical paths, which have a diameter about 2 μm, must be used. Conventional fibers are larger in size - about 10μm. Therefore we need a tapered structure to connect these types of optical paths. We found that transmission efficiency of taper depending on the parameters as length, curvature on either side, upper curve, etc... In this report, we focus only on the influence of the lateral curvature on the taper transmission coefficient.

Potassium (K), calcium (Ca), and magnesium (Mg) are important nutrients for the pummelo’s growth and productivity. However, these nutrients are strongly antagonistic to each other. This study aims to examine the effects of different K, Ca, and Mg ratios in soil on nutrient uptake of pummelo plant. Soil samples were collected under pummelo canopies at a depth of 0 cm to 20 cm. Leaf samples of 3 to 5 month old were obtained from the same trees. The soil’s chemical properties and nutrient concentrations in the leaves were determined. The results showed that the P uptake was inhibited by a high Ca concentration in soil. High K/Mg ratio in soil (0.52 ± 0.27) positively affected on K uptake. Low K/Mg ratios in soil (0.42 ± 0.20) negatively affected on K uptake, although exchangeable K in soil was much higher than optimum ranges. The K/Ca mole ratio in the leaves was higher than that in the soil; therefore, the uptake of K was better than that of Ca, despite the lower concentration of K in the soil. Moreover, the uptake of K was better than that of Mg, because the K/Mg ratio in the leaves higher than that in the soil. Low exchangeable Ca negatively affected on Ca uptake, although Ca/Mg mole ratio in soil was high (2.77 ± 1.18).
