In the paper, the authors discuss the concept of staged readings, arguing that they are the predominant performance format for presentations of young playwriting. However, such presentations should not be understood as an intermediate stage between reading and performing but as a fully-fledged and independent artistic genre. Many staged readings thus lose the function of “first information” about the text and its author. Instead, they have become a proper way of performing a text, thus opening up a wider area for theatrical experimentation. Using concrete examples, the authors will reflect on practices characterised by the text becoming the main or even the only thing necessary for a theatrical event and reading (in all its possible ways and forms) becoming the key theatrical means.
Noise filtering options for conically scanning Doppler LiDAR measurements with low pulse accumulation
Authors: Päschke Eileen , Detring Carola
Published: August 2023

Abstract. Doppler lidar (DL) applications with a focus on turbulence measurements sometimes require measurement settings with a relatively small number of accumulated pulses per ray in order to achieve high sampling rates. Low pulse accumulation comes at the cost of the accuracy of radial velocity estimates and increases the probability of outliers, also referred to as "bad" estimates. Careful noise filtering is therefore the first important step in the data processing chain from raw data to the retrieved turbulence variable. It is shown that commonly applied filtering techniques have weaknesses in distinguishing between "good" and "bad" estimates with the sensitivity needed for a turbulence retrieval. For that reason, new ways of noise filtering have been explored, taking into account that the DL background noise can differ from generally assumed white noise. It is shown that the introduction of a new coordinate frame for a graphical representation of DL radial velocities from conical scans offers a different perspective onto the data when compared to the well-known velocity-azimuth-display (VAD) and thus opens up new possibilities for data analysis and filtering. This new way of displaying DL radial velocities builds on the use of a phase-space perspective. Following the mathematical formalism used to explain a harmonic oscillator, the VAD’s sinusoidal representation of the DL radial velocities is transformed into a circular arrangement. Using this kind of representation of DL measurements, "bad" estimates can be identified in two different ways. Either in a direct way, by singular point detection in subsets of radial velocity data grouped in circular rings, or indirectly, by localizing circular rings with mostly "good" radial velocity estimates by means of the autocorrelation function. The improved performance of the new filter techniques compared to conventional approaches is demonstrated, both through a direct comparison of unfiltered with filtered data sets, and through a comparison of retrieved turbulence variables with independent measurements.
Determining the ultraviolet radiation dose experienced by aerosols using ultraviolet-sensitive dyes
Authors: Fu Qingqing , Kruis Einar
Published: August 2023

Abstract. The application of ultraviolet (UV)-based air disinfection holds promise, but also presents several challenges. Among these, the quantitative determination of the required UV radiation dose for aerosols is particularly significant. This study explores the possibility of determining the UV dose experienced by aerosols without the use of virus-containing aerosols, circumventing associated laboratory safety issues. To achieve this, we developed a model system comprised of UV-sensitive dyes dissolved in di-ethyl-hexyl-sebacate (DEHS), which facilitates the generation of non-evaporating and UV-degradable aerosols. For the selection of UV-sensitive dyes, 20 dyes were tested, and two of them were selected as most suitable according to several selection criteria. Dye-laden aerosol droplets were generated using a commercial aerosol generator and subsequently exposed to UVC radiation in a laboratory-built UV irradiation chamber. We designed a low-pressure impactor to collect the aerosols pre- and post-UV exposure. Dye degradation, as a result of UV light exposure, was then analyzed by assessing the concentration changes in the collected dye solutions using a UV-visible spectrophotometer. Our findings revealed that a UV dose of 245 mW·s·cm-2 resulted in a 10 % degradation, while a lower dose of 21.6 mW·s·cm-2 produced a 5 % degradation. In conclusion, our study demonstrates the feasibility of using aerosol droplets containing UV-sensitive dyes to determine the UV radiation dose experienced by an aerosol.
Ellipsoid contact analysis and application in the surface conjugate theory of face gears
Authors: Chu Xiaomeng , Liu Yali , Zeng Hong
Published: August 2023

Abstract. The face gear tooth surface is a high-order variable curvature surface, and the curvature of the surface is complicated, so it is difficult to describe the characteristics of the face gear tooth surface by a specific equation. In this paper, the discrete curvature relation of the surface is used instead of an analytical equation to describe a spatial meshing surface, and the traditional meshing theory is neutralized to analyze the characteristics of the face gear tooth surface. Firstly, according to the structural characteristics of the face gear, the sampling method of the face gear tooth surface is analyzed, and the mathematical model of fitting the tooth surface contact point is established. Then, the discrete asymptotic surface development analysis method is studied, and the ellipsoid contact analysis method of the face gear pair is established by
simplifying the conjugate surface and its region. Finally, the contact analysis method of the discrete tooth surface is studied, and the
instantaneous contact ellipse of the face gear tooth surface is calculated, which formed a new numerical meshing method of space curved surface.

Authors: Samra Partap Singh , Singh Lakhvir
Published: August 2023

Finishing of cylindrical workpieces of SUS304 steel has been done using loosely bonded diamond based magnetic abrasives prepared by homogeneous mixing of magnetic powder (Fe powder of 300 mesh size (51.4μm)), abrasive powder (Diamond particles of 200 mesh size (41μm)), and lubricant. A central composite design involving four variables has been employed using RSM techniques to establish a mathematical model between parameters and response (percent improvement in surface finish), a series of experiments have been conducted using in-house fabricated setup. It has been found that magnetic flux density, quantity of magnetic abrasives, rotational speed of workpiece and percentage of abrasives in magnetic abrasives has significant effect on PISF. The maximum percentage improvement in surface finish was found to be 81% (0.04 μm Ra) at 1.0 Tesla of magnetic flux density, 40 mg of magnetic abrasives, 800 rpm as rotational speed of workpiece and 40% of abrasive. Scanning Electron Microscope (SEM) photographs shows that the surface generated by turning on lathe consists of deep scratches. The peaks have been sheared off to much smaller heights by MAF resulting in improved surface finish, but fine scratching marks produced by MAF appear on the surface.

Effect of Process Parameters on Surface Roughness of Mild Steel Processed by Surface Grinding Process
Authors: Balwinder Singh  , Balwant Singh
Published: August 2023

Surface grinding process is used mainly to grind flat surfaces. There are many conditions in manufacturing,where the work-piece material is either too hard or its shape is difficult to produce with sufficient accuracy by any other cutting methods, one of the best methods for producing such parts is to use abrasives. Grinding is basically a chip removal process in which the cutting tool is an individual abrasive grain. Surface grinding process cannot be efficiently carried out without the correct fluid. In the present study Horizontal spindle and reciprocating table type surface grinding machine fitted with test rig is used and cutting fluid is applied through the convergent nozzle to throw the cutting fluids at the cutting zone. This process can be utilized to create flat shapes at a high production rate and low cost. This paper investigates the effect of process parameters such as grinding wheel speed, work-piece speed and nozzle angle on the surface roughness value of mild steel specimen produced by surface grinding process. In order to evaluate the effect of selected process parameters, one variable approach has been used in the present study. Plots of various output responses have been used to determine the relationship between the output response and the input parameters. The value of surface roughness of grinded mild steel work-piece varies from 0.77 μm to 0.79μm.

Authors: Kumar Harmesh , Manna Alakesh , Kumar Rajesh
Published: August 2023

In this experimental study, wire cut electrical discharge machining (WEDM) is adopted in machining of silicon carbide particulate reinforced aluminium metal matrix composites (Al/SiCp-MMCs). In the experiments total six machine input parameters are varied using one factor at a time strategy to explore their effect on response characteristics including cutting speed, surface roughness and spark gap. Moreover Wire breakage was found to pose limitations on the cutting speed of MMCs. The present study also investigates the causes of wire breakage in machining of Al/SiCp-MMCs and suggests their remedial actions. Reinforcement percentage of SiC particles and pulse on time are found to have significant effect on the response characteristics. Test results reveal that in machining of Al/SiCp-MMCs, higher cutting speed could be achieved with optimum setting of pulse off time and spark gap set voltage without wire breakage. Additionally high wire feed rate, a high flushing rate and setting of optimum wire tension is required to avoid wire breakage. An optimum range of machine input parameters has been reported as the outcome of this work for the successful machining of Al/SiCp-MMCs with minimum chances of wire breakage for further research in this area.

Authors: Bandyopadhyay S.
Published: August 2023

Unsaturated polyester resin (UPR) has the resistance against boiled water, acid and alkali, and hence, is widely used in corrosive environment and elsewhere, although fracture strength of polymeric materials is generally low relative to metals and ceramics. Despite the fact that polymer components are mostly produced near-net-shape, machining, particularly drilling, is often required to prepare it for assembly. In the present paper, drilling of unsaturated polyester resin is undertaken for the evaluation of machinability of unsaturated polyester resin (UPR). Observation of cutting force requirement, type of chip formation, and eccentricity of drilled holes produced are made. Formation of burr at the edge of drilled hole is also explored under varying cutting conditions.

Published: August 2023

Healthcare is a promising application of the cloud computing technology. Healthcare network over the cloud has been described in this paper. The existing processes for patients’ vital data collection require a great deal of labor work to collect, input and analyze the information. These processes are usually slow and error prone, introducing a latency that prevents real-time data accessibility. This scenario restrains the clinical diagnostics and monitoring capabilities. A solution has been proposed to automate this process by installing health kiosk and integrate the devices. The information becomes available in the “cloud” from where it can be processed by expert systems and or distributed to medical staff. This design is able to make the system more user-friendly while retaining all the benefits of more complicated processes.

With the character of low maintenance, cloud computing provides an economical and efficient solution for sharing group resource among cloud users. Unfortunately, sharing data in a multi-owner manner while preserving data and identity privacy from an untrusted cloud is still a challenging issue, due to the frequent change of the membership. In this paper, we propose a secure multiowner data sharing scheme, named Mona, for dynamic groups in the cloud. By leveraging group signature and dynamic broadcast encryption techniques, any cloud user can anonymously share data with others. Meanwhile, the storage overhead and encryption computation cost of our scheme are independent with the number of revoked users.

A Capable System for Hiding Image in an Image
Authors: Ganesh R. , Thabasu Kannan S.
Published: August 2023

In this paper, we have proposed a new method by for hiding an image using steganographic called GanKan. This method is based on Least Significant Bit (LSB) replacement and can be used for 24 bit color image capable of producing a secret-embedded image. This paper clearly showed that this GanKan new method is better than LSB technique for 8 bit color image and 24 bit color image. Firstly LSB method for both 8 bit and 24 bit color image are described and then the GanKan method for 24 bit color image, compare their result by calculating Peak Signal-to-Noise Ratio (PSNR), Mean Squared Error (MSE), Root Mean Square Error (RMSE) and histogram analysis. LSB Algorithm embedded MSB of secret image into LSB of cover image. In the case of 24 bit color image two methods are described. In first method, last 2 LSB of each plane (RGB) of cover image, is replaced by 2 MSB of secret image. In the second method, last LSB of each red plane is replaced by first MSB of secret image, last 2 LSB of each green plane by next 2 MSB of secret image and then last 3 LSB of blue plane is replaced by next 3 MSB of secret image. This means that total 6 bits of secret image can be hided in 24 bit color image. Experimental results showed that the embedded-image is visually indistinguishable from the original cover-image in the case of 24 bit.

Published: August 2023

Australia has the highest rate of melanoma worldwide. It is estimated that 1,300 people will die from metastatic melanoma in 2023. Melanoma is highly mixed, or heterogeneous, as a result of the cancer cells evolving diversely over the course of the disease. This project focuses on how tumour heterogeneity is involved in melanoma progression and spreading. We mixed different populations of cells to mimic the heterogeneity state in the tumour, to understand how the cells grow, migrate and invade. The outcome of this study may be important in developing new therapeutic options especially for advanced melanoma patients.
Conocer, exhibir y aprehender visualmente el territorio nacional: la monarquía isabelina (1833-1868), una Galería de costumbres de todas las provincias de España de Manuel Rodríguez de Guzmán (1818-1867) y otras imágenes de la nación en Palacio
Authors: Cánovas Moreno Álvaro
Published: August 2023

A lo largo del siglo XIX, la mayoría de países se vieron sumidos en complejos procesos de nacionalización. Es decir, se trató de que la ciudadanía de esos países naturalizara y asumiera su pertenencia a una nación. Y las monarquías no fueron ajenas a este fenómeno; pues los reyes y reinas de la centuria intentaron asumir o encabezar el proyecto nacionalizador.

Los distintos agentes nacionalizadores se valieron de todo tipo de mecánicas, canales y soportes. No obstante, las imágenes jugaron un papel fundamental. Y atendiendo a que, en su expresión más elemental, el concepto nación refiere a una población y a unas costumbres determinadas, así como a un territorio concreto, creemos que sus representaciones visuales se resuelven como una atalaya privilegiada para comprender el complejo fenómeno de nacionalización española. Especialmente, en el caso de la monarquía isabelina (1833-1868).

Nuestro trabajo analiza el modo en que el trono desarrolló este proceso nacionalizador desde las representaciones visuales del territorio de la nación, así como su población y costumbres. Sin embargo, nos centraremos en la Galería de costumbres de todas las provincias de España que Isabel II encargó al pintor costumbrista Manuel Rodríguez de Guzmán (1818-1867) en 1853, para exhibir en Palacio. Un conjunto que reflejaba la nueva división territorial por provincias, aprobada en 1833. Igualmente, tanto el análisis de los lienzos realizados para el conjunto como los textos explicativos que para él se crearon, permiten estudiar los distintos aspectos que fueron enfatizados a la hora de representar visualmente la nación.
Comparison of Mental Health Professionals in terms of Locus of Control, 5-Factor Personality Test, Defense Styles and Coping Styles According to the Psychotherapy School They Feel They Have in Practice
Authors: KIVRIKOĞLU Funda
Published: August 2023

Personality plays an active role in all our behaviors, choices, beliefs and mechanisms to protect ourselves. It seems possible that there is an interaction between the career choices of mental health professionals, who are a professional group working on the structure and dynamics of personality, and their personality structures. Mental health professionals continue to work with many different schools. These are predominantly psychodynamic school and psychoanalysis, cognitive behavioral therapy, gestalt school and eclectically a combination of these and other schools. The aim of this research is to reveal the differences of professionals working in the field of mental health according to the psychotherapy school they choose, according to locus of control, five-factor personality scale, defense strategies and coping styles. The schools preferred by mental health professionals were examined in 3 different groups as "Psychoanalysis/Psychodynamic Therapy", "Cognitive Behavioral Therapy" and "Eclectic Approach". 90 people, including 21 psychiatrists, 29 psychological counselors and 40 psychologists, from the province of Istanbul participated in the research. In the evaluation of personality traits, four different scales were used: "Locus of Control Scale", "Five-Factor Personality Scale", "Defense Strategies Scale" and "Coping Styles". According to the results obtained from the research, it was seen that there was no significant difference between the schools chosen by the mental health experts in the direction of the research and the personality structures. However, it indicates that the neuroticism sub-dimension score has decreased over the years. Finally, a significant difference was found between individuals who adopted the CBT school and the sub-dimension of responsibility.

This article discusses the education and teaching of the Qur’an in schools. In order to produce a generation that excels in ethics, akhlaqul karimah. So each school has different visions and missions, with these differences there is a common thread that can be applied simultaneously, namely the application of learning the Qur'an. This study will discuss the methods used in learning the Qur’an, common problems, and solutions to the problems of learning the Qur’an in schools. The model for writing this article is by using a descriptive-analytic methodology, based on library research. The results of this study are that there must be continuity between teachers, students, schools, parents, the environment, and their relatives. So that it will be born from every school of generations who have good morals with the basis of the Qur'an as a guide to their lives. It will also bring the souls of the students closer to the Qur'an, which is expected to bring peace, prosperity, and happiness not only in this world, but also in the hereafter.

Background: PtRu/C electrocatalysts present good results in methanol electo-oxidation. The activity of these electrocatalysts is strongly dependent on the synthesis method. Additionally, the use of mesoporous carbons or nanostructured carbons increases the performance of electrocatalysts applied in alcohol electro-oxidation. The hydrothermal carbonization method is an alternative to obtain different nanoarchitectures without involving harsh conditions. Aims: Thus, this work aimed to evaluate the influence of synthesis time on the properties of PtRu/Carbon hybrids prepared by the hydrothermal carbonization method. Methods: PtRu/Carbon hybrids were prepared by hydrothermal carbonization at different times of synthesis (6 h and 12 h). It used cellulose as a carbon source and reducing agent and H2PtCl6.6H2O and RuCl3.xH2O as metal sources and catalysts of the carbonization process. The materials were treated at 900 °C and characterized by energy-dispersive X-ray spectroscopy, thermogravimetric analysis, B.E.T isotherms, X-ray diffraction, transmission electron microscope and cyclic voltammetry. The electro-oxidation of methanol was studied by chronoamperometry. Results: The increase in synthesis time from 6 to 12 hours, apparently, resulted in an increase in mean particle size, reduction of mesoporous volume and increase in superficial area and total pore volume. The chronoamperometry of methanol electro-oxidation on these PtRu/Carbon hybrids indicated a higher electroactivity to the material prepared in 6 hours. Discussion: Probably, the higher electroactivity of material prepared in 6 h is associated with smaller particle size, mesoporous structure and surface oxides content. Conclusions: Therefore, it is possible to affirm that the synthesis time is an important parameter that affects the physical-chemical properties of metal/carbon hybrids obtained by the hydrothermal carbonization method.

Background: Agriculture is a vital part of the economy that feeds a part of the world expanding population. However, the sector faces several difficulties, including water constraints, soil degradation, and climate change. The demand for increased security and safety in agricultural activities worsens these problems. This paper suggests an IoT-based agriculture environment and security monitoring system address these issues. Aims: The main objective of this work is to develop an intelligent monitoring and automated irrigation system that minimizes water use based on individual conditions and enables real-time environmental Methods: The Arduino Uno R3 microcontroller based on Microchip ATmega328P is used to gather environmental data such as humidity, temperature, soil moisture levels. The Arduino board is integrated with a relay and RTC module to water plants at precise times. It also has a passive infrared sensor to detect intruders. ESP32 camera is also used to record the current condition of the agricultural ground automatically. A sample of reading in an interval of 1 hour is recorded. This method involves wirelessly transmitting the data to cloud-based platforms. Results: The value of the sensor at the start of a wet condition is 0. When this occurs, the motor pump turns off, and the measured value is communicated to the microcontroller through NodeMCU. The motor pump automatically turns ON and OFF when plants receive enough amount of water. Discussion: It has been observed the water pump starts as soon as the temperature threshold of 19.5 °C is achieved. It has been observed that as humidity increases, it is unnecessary to water the plants as the plants take up water vapor from the surface of the leaves under humid conditions. Conclusions: This research offers a convenient prototype model that can simultaneously measure temperature, moisture, and humidity, identify intrusion, and remotely monitor it over the internet. It was concluded that with the decrease in moisture of the soil, the plants need to be watered.

Background: The quest for new energy sources is one of the most significant aspects of the renewed environmental consciousness that prevails in the contemporary world. The omnipresent use of fossil fuels and other harmful sources became one of the principal worries of the political and scientific communities, that since the past century started a campaign in search of alternatives. Aims: The aim of was to discuss contributions of energy recovery derived from MSU to the Brazilian panorama of electrical sources, adopting circular economy applied to a municipality. Methods: a revision of the literature was undertaken, to gather concepts and cases, taking circular economy, waste management and municipality as keywords. Results: The gathered papers present the prominence of circular economy in the intellectual scenario of environmental debate; also, a lack in previous treatment of collected residue, especially the sorting of materials by population, which impacts negatively the recovery. Discussion: The key aspects of the problem include promoting popular engagement in the cycle, identified as an important asset for a successful process. This includes the latin american scenario, that began to change recently with pilot plans implemented in some regions. The efficient way is to engage both industry and population in the process. Conclusions: One of the cleaners panoramas of energy sources, such facility could be installed in Brazil, following a south American upraising that already has Santa Rosa, Peru, and Barueri, in Brazil itself. An opportunity to develop regions and municipalities.
