The COVID-19 pandemic and its impact on mental health has remained immense and global in all senses. Various types of induced psychiatric disorders, both new episodes and exacerbation of the preexisiting ones has been reported - starting from adjustment disorder to full psychotic illnesses.
Various clinical symptoms, including systematized delusions, affective symptoms and self harm ideas has been mentioned needing upto prolonged admission and in patient care. Various etiopathogenetic models, incluing direct neural infection to cytokine storms or unmasking of the hidden vulnerabilities has been proposed however this needs further research. Traditional antipsychotic pharmacological agents has been proven to work well though special attention to pharmacological interactions is needed with caution for co morbid conditions and chance of side effects.
We collaborated in worldwide Task Force of early career psychiatrists and prepared the definition of our point of view.
Old English Power Structure in the Warlike Nature in Riddles no. 3, no, 29, no. 50 from the Exeter Book
Authors: Widodo Herditya Wahyu
Published: September 2021

Abstract: This study focuses on Old English nature-themed riddle texts from the Exeter Book, analyzing the natural imageries that are significant in investigating how the literary content of Old English riddles, as accepted forms of poetry, reveals the Anglo-Saxon culture of their original authors. I focus on the power structure in Anglo-Saxon society revealed in the riddles, by analyzing the topic of warlike nature in them, focusing on the riddles no. 3, “Storm”, no. 29 “Sun and Moon,” and no. 50, “Fire.” Natural experience described in these riddles is rendered by the Anglo-Saxons to reflect power hierarchy between male and female, servant and master, and human with God.  The Anglo-Saxon riddles identify and assign the potent warlike attributes and actions of nature, and assign them to the more powerful factions (God, Master, Male) over the weaker factions (Humans, Servants, Female). This is done by the authors as an acceptable cultural interpretation of these natural phenomena, put in the riddles to make it possible for the riddles’ intended Anglo-Saxon audience as clues to arrive at a culturally agreeable answer.

Abstrak: Studi ini berfokus pada teks teka-teki (Riddles) Inggris Kuno (Old English) bertema alam dari the Exeter Book, dengan menganalisa imaji alam yang signifikan, untuk mengetahui bagaimana teka-teki Inggris Kuno, sebagai salah satu karya sastra berbentuk puisi, mengungkapkan budaya Anglo-Saxon dari penulis aslinya. Saya berfokus pada struktur kekuasaan (power structure) dalam masyarakat Anglo-Saxon yang terungkap dalam teks teka-teki, dengan menganalisis topik sifat suka perang di pada teka-teki no. 3, "Badai", no. 29 “Matahari dan Bulan,” dan no. 50, "Api." Pengalaman hidup mengenai alam digambarkan dalam teka-teki ini oleh para penulis Anglo-Saxon dengan mencerminkan hierarki kekuasaan antara laki-laki dan perempuan, hamba dan tuan, dan manusia dengan Tuhan. Teka-teki Anglo-Saxon mengidentifikasi dan menetapkan atribut dan tindakan alam yang suka berperang (warlike) kepada faksi yang lebih kuat (Dewa, Tuan, Laki-Laki) di atas faksi yang lebih lemah (Manusia, Pelayan, Wanita). Hal ini dilakukan oleh para penulis sebagai interpretasi budaya atas fenomena alam yang mereka lihat, dan dimasukkan ke dalam teka-teki untuk memungkinkan pembaca Anglo-Saxon sebagai petunjuk untuk sampai pada jawaban yang dapat diterima secara budaya.

Graded concrete is one of the steps to reduce the use of cement in construction as well as to optimize the mechanical characteristics of the planned structural elements. This study aims to analyze the maximum load performance, deflection, stiffness, ductility, and failure patterns of graded concrete beams with variations in the quality of concrete in the compression fiber and tensile fiber. Gradation beams are made from a combination of 2 (two) different quality mixtures, namely 30-40 MPa, 30-50 MPa, and 40-50 MPa. The flexural testing of the concrete beams was carried out at the age of 28 days. The failure pattern of the graded concrete beams for each test object was observed and compared with the control concrete beams. The test results show that graded concrete blocks with uniform tensile strength of concrete produce higher beam loads, stiffness, and ductility as the quality of the concrete used in compression fibers increases. Beams with uniform compression fiber and different tensile fibers have higher load, stiffness, and ductility values as the concrete quality increases in the tensile fiber portion of the beam. The resulting beam deflection still meets the allowable deflection. Based on this, the graded concrete beam is declared to have good serviceability.Keywords: Graded Concrete Beam, Stiffness, Ductility, Failure Pattern
Experimental testing of scroll machine driven by compressed air for power generation and its integration in small scale organic Rankine cycle
Authors: REDDY Pavan Kumar , BHAGYASHEKAR M S
Published: September 2021

Organic Rankine Cycle (ORC) is a proven technology in the field of waste heat recovery and present days ORC is extensively being used in exploiting biomass, geothermal and solar energy. The overall performance of ORC depends on the expander, making it a core component of the system. Generally, these expanders are classified into velocity type and displacement type. The velocity type expanders find their applications in large scale power generation and are not preferred in small scale power applications as their rotational speeds exponentially increase with a decrease in expander power output. As a result, the displacement type expanders are best suited for small scale power generation in ORC. Yet, till date expanders capable of producing power at small scale are not commercially available in the market for ORC application. As an effect commercially available scroll compressors are modified to work as expanders in ORC systems. The present study aims to examine the feasibility of using one such scroll compressor as an expander in ORC with and without modification. A test rig was developed to test the compressor running in reverse as expander using compressed air, before and after modifications. The scroll machine was tested for operating conditions consisting of pressure varying from 0.5 bar to 4.5 bar and the load varying from 0.2 kg to 2.2 kg for a constant airflow rate. The configurations tested were, scroll compressor with the suction port as inlet, modified scroll compressor with the suction port as inlet and modified scroll compressor with discharge port as an inlet. Based on the experimental test data obtained it is observed that, in all three configurations, for various loading conditions at given inlet air pressure there exists a maximum power generation point and a further increase in the load at given pressure has a negative effect on power output. Also, a significant increase in speed is observed from 300 to 4250 rpm at no load condition with increasing inlet air pressures. Maximum power of 210 W was achieved at a load of 1.1 kg with the inlet pressure of 4.5 bar for modified scroll machine when the discharge port was used as an inlet. Finally, it is recommended to use a modified scroll machine with discharge port as inlet as it gives more power when compared with other configurations for the same operating conditions.
Effect of fibrous porous material on natural convection heat transfer from a horizontal circular cylinder located in a square enclosure
Authors: MAJDI Hasan Shakir , MOHAMMED Akeel Abdullah , MOHAMMED Amer Abdullah , HABEEB Laith Jaafer
Published: September 2021

A numerical simulation study was carried out to investigate a steady two-dimensional laminar natural convective heat transfer from a uniformly heated inner circular cylinder placed inside an air-filled square enclosure with a porous material. The enclosure’s side and upper walls were isothermal, while the bottom wall was adiabatic. All the numerical calculations were performed in the range of Rayleigh numbers between 103 and 107. The material porosity (ε), the solid to fluid thermal conductivity ratio (kr), and Darcy number in the present study were 1.0, 0.5, and 0.01, respectively. The results showed that for Rayleigh numbers that are less than 106, the isotherms are almost parallel inside the three cold walls except for the corners of the adiabatic bottom wall. The rates of vertical velocity are higher than the horizontal velocity, especially at higher Grashof numbers. Also, the use of fibrous porous material with low thermal conductivity relative to the fluid thermal conductivity reduces the values of average Nusselt number, in addition to reducing the horizontal and vertical velocities along the horizontal axis.

Published: September 2021

Encapsulation of Phase Change Materials (PCM) for energy storage, thermal comfort and many other energy applications is receiving much attention due to the fact that material, physical characteristics and geometry of the container can affect drastically the thermal performance of the PCM. Phase change materials have usually low thermal conductivity which impairs their thermal charging and discharging characteristics. Different geometries were investigated including rectangular, cylindrical and spherical with and without extended surfaces to investigate the heat charge processes. Cylindrical geometries of circular sections were intensively investigated while cylinders and tubes with elliptic and elongated cross section received less attention, although they may have better thermal performance for thermal storage.
The present numerical investigation is aimed at contributing to better understand the effects of the elliptic geometry and how the different geometrical and operational parameters can affect the thermal performance of the enclosed PCM. The present investigation reports the results of a numerical study on elliptic cylinders containing PCM under melting conditions. The 2D inward melting problem is modeled by using a CFD code. The numerical model is based upon the enthalpy-porosity method along with the finite control volume techniques. The numerical predictions are validated against available experimental results. The inward melting process is analyzed for two orientations of the elliptic enclosures. Due to the flow field effect namely the Rayleigh-Bénard convection, the numerical results showed that the horizontal elliptic enclosure have higher melting rate and hence lower total melting time compared to those of the vertical elliptic enclosure.
La fundación de Estados Unidos y el ocaso del pensamiento político clásico
Authors: Corcho Hernández David
Published: September 2021

Este artículo analiza cómo la expansión del comercio y la manufactura afectaron al pensamiento político clásico en la última etapa de las Trece Colonias y los primeros años de Estados Unidos. Gracias a una combinación de análisis histórico y de teoría política, observa los cambios inducidos por la sociedad comercial en aspectos clave del pensamiento político clásico, como la representación, propiedad, libertad y el sentido de la historia. Su principal aporte está en buscar causas para esas transformaciones doctrinales en factores extradiscursivos, pues buena parte de la bibliografía sobre la historia de las ideas políticas en esta etapa se centra en los “lenguajes” e “ideologías”.
Analyzing and Detecting Drifts in a Flowmeter by Discrete Fourier Transform
Authors: Ben Salamah Mohammad J. , Savsar Mehmet
Published: September 2021

Large flowmeters are used in many industrial facilities, including power plants, cooling-water stations for refineries, and petrochemical plants. These flowmeters are employed for various purposes, including billing. Just like all machines, flowmeters are subject to failure. Drift is a particular type of failure in which the flowmeter produces an error in measurement that would incrementally increase with time. Maintenance technicians calibrate and fix all measuring equipment, including flowmeters. Nevertheless, downsizing policies and budget cuts in most contemporary industrial facilities have made these technicians overwhelmed with work. A mathematical and computer-based drift-detection scheme is developed to reduce the burden of the maintenance staff. The detection scheme only uses the flowmeter's flow data and the discrete Fourier transform (DFT). The detection scheme was applied over the flow data from an actual flowmeter that drifted during its operation. DFT application over the data produced by the flowmeter led to expected results and other unexpected results. This paper discusses both results and suggests areas for further study. Practically speaking, the scheme would facilitate the early detection of drifts in flowmeters having seasonal flow regardless of type or manufacturer.

Published: September 2021

A mathematical model of reaction-diffusion problem with Michaelis-Menten kinetics in catalyst particles of arbitrary shape is investigated. Analytical expressions of the concentration of substrates are derived as functions of the Thiele modulus, the modified Sherwood number, and the Michaelis constant. A Taylor series approach and the Akbari-Ganji's method are utilized to determine the substrate concentration and the effectiveness factor. The effects of the shape factor on the concentration profiles and the effectiveness factor are discussed. In addition to their simple implementations, the proposed analytical approaches are reliable and highly accurate, as it will be shown when compared with numerical simulations.
Improvement of Static Voltage Gain of a Non-Isolated Positive Output Single-Switch DC-DC Converter Structure Using a Diode-Capacitor Cell
Authors: Murali D. , Annapurani S.
Published: September 2021

There are different low switching stress non-isolated DC-DC power converter structures developed for Photo-Voltaic (PV) applications with a view to achieve high voltage conversion ratio. The work proposed in this research article investigates the performance analysis of a coupled inductor and diode-capacitor multiplier cell based non-isolated high gain single-switch DC–DC conversion scheme with a single-ended primary-inductor on the input side. The presented converter suitable for renewable energy applications has the merits such as continuous input current, high voltage conversion ratio, and reduced voltage stress across the power switch. The multiplier cell consisting of two diodes and two capacitors is mainly used to enhance the converter output voltage level. A MATLAB / SIMULINK model of the suggested topology has been developed to validate its performance. During the simulation of the converter, a DC voltage of 50 V was given at the input side. The load end received a DC voltage of approximately 900 V. Thus, through this study, it was found that the addition of diode-capacitor cell can significantly improve the static gain of the suggested converter. The findings of this research may serve as a base for future studies on improvement of voltage gain of DC-DC converters.

Published: September 2021

Backward facing step arrangement is a classical case for fluid dynamics and heat transfer research. It is well characterized and therefore, used for benchmarking. However, ongoing studies reveal that the geometry also provide advantages in industry, especially in combustion and burners. This work utilizes computational fluid dynamics to investigate a specific laminar back facing step flow heat transfer case. Aluminium oxide nano particles are considered as an additive to water base fluid, forming nanofluid with different volumetric concentrations. Laminar flow passes a back facing step and encounters three circular grooves at bottom surface. All surfaces are adiabatic except the grooves. Constant surface temperature applies to the grooves. According to the simulation results, a separation bubble after back facing step and a reattachment point occur. Grooves alter expected wake due to physical and thermal interference. Investigation parameters are nano-particle concentration and Reynolds number. Reynolds number changes between 10 and 250. Nano particle volume fraction percentage changes between 2 and 6 percent. Sectional heating downstream of the step poses interesting heat flux in the presence of Aluminium oxide nano-particle concentrations. There is a pseudo-linear relationship between parameters and heat transfer. Combined effects of enhanced thermal conductivity and secondary flow structures are seen. As expected, thermal convection increases as flow velocity and nano-particle concentrations increase. Heat flux and accordingly Nusselt number are highly affected from Reynolds number since flow structure changes dramatically. Also, direct proportion is seen between nano-particle concentration and enhanced convection.
Joint Power Allocation and Bit-Loading for Multicarrier Systems with Discrete Modulation
Authors: Nofal Abdul-Nasser , Assimi Abdel-Nasser , Jaamour Yasser M.
Published: September 2021

In this paper, we propose two algorithms for joint power allocation and bit-loading in multicarrier systems using discrete modulations. The objective is to maximize the data rate under the constraint of a suitable Bit Error Rate per subcarrier. The first algorithm is based on the Lagrangian Relaxation of the discrete optimization problem in order to find an initial solution. A discrete solution is found by bit truncation followed by an iterative modulation adjustment. The second algorithm is based on Discrete Coordinate Ascent framework with iterative modulation increment of one selected subcarrier at each iteration. A simple cost function related to the power increment per bit is used for subcarrier selection. A sub-optimal low complexity Discrete Coordinate Ascent algorithm is proposed that overcome the limitations of the Hughes-Hartogs algorithm. The Lagrangian Relaxation algorithm provides a suboptimal solution for non-coded system using M-QAM modulations, whereas the low complexity Discrete Coordinate Ascent algorithm provides a near optimal solution for coded as well as for non-coded system using an arbitrary modulation set. Numerical results show the efficiency of the proposed algorithms in comparison with traditional methods.

Published: September 2021

The main goal of this research is to calculate a triple integral included continuous integrands numerically by two composite rules. The first rule is the Mid-point method on the third dimension Z and the first dimension X with a suggested method on the second dimension Y, that is denoted by MSuM. The second rule is the suggested method on the third dimension Z and the first dimension X with a Mid-point method on the second dimension Y, that is denoted by SuMSu. The number of partial intervals is equals on the three dimensions. The study represented two theorems with the proofs to get such rules and the correction terms (the error terms) for each of rule. Moreover, to accelerate convergence and get better results, Romberg acceleration is used with both rules. These rules recalled by RO(MSuM) and RO(SuMSu) respectively such that the obtained results were high accuracy by relatively few partial intervals and shorter times.
Vida de sanitarista
Authors: Hamilton Mario
Published: September 2021

Este libro no es un informe de investigación sino el relato de una vida apasionante, pero incluye un minucioso informe de acciones en el terreno de la salud desde el punto de vista organizativo y administrativo, que son un aporte fundamental para la comprensión y el desarrollo de esas actividades en América Latina, en particular, en Brasil y Argentina. La actividad educativa de Mario no se limitaba al aula. También en su tarea de administrador y organizador enseñaba y transmitía saberes y prácticas. Prueba de ello son desde los remotos tiempos de la encuesta de morbilidad en Argentina hasta los multitudinarios congresos internos de la Fiocruz, donde su presencia era un estímulo permanente para que todos los funcionarios, de cualquier nivel, pensaran con fervor militante los procesos de la actividad. Toda su vida fue eso que postulé como la forma de incorporación de los descubrimientos que se realizan en las disciplinas que forman parte de las ciencias sociales. Esos productos no se incorporan a las prácticas profesionales mediante lo que es habitual en las ciencias fácticas —la incorporación tecnológica— sino a través de lo que llamé la militancia sociopolítica del científico social, de la que es un ejemplo —otra vez— paradigmático, el recorrido profesional de Mario. El compromiso militante de Mario era permanente, desde los tiempos de los equipos político-técnicos en Argentina, hasta la solidaridad política en el exilio primero y ya incorporado en plenitud a la vida brasileña, desde donde irradió ese compromiso hacia los diversos movimientos que luchaban con la consigna de la salud como deber del Estado y derecho del pueblo (CEBES, ABRASCO, el “partido sanitario”), y el permanente intento de una práctica centrada en la creación de un Servicio Único de Salud.
