Numerical Modeling of Electric Discharges Generated in Supersonic Flows
Authors: Nekris Alexander , Gnemmi Patrick , Mundt Christian 
Published: January 2023

A numerical solver is developed for the modeling of electric discharges in high-speed flows. For the formulation of the physicochemical model, common electric discharge modeling approaches are combined with detailed models for nonequilibrium aerothermodynamics and finite-rate chemical kinetics. The physicochemical model is based on the single-fluid assumption and takes into account the thermal and chemical nonequilibria in the gas mixture. For the numerical implementation, the finite-volume-based open-source CFD software package OpenFOAM is used. The verification of the calculation models for thermodynamic and transport properties as well as finite-rate chemical kinetics is carried out by means of one-dimensional simulations. The first validation of the solver is carried out by means of a three-dimensional simulation of an electric discharge with a constant input power of 10 kW generated on the surface of a wedge in a supersonic nitrogen flow. The numerically obtained results are compared with corresponding experimental measurements and theoretical calculations and show a fair agreement. The numerically calculated maximum temperature values, for example, are 20–40% above the measured values. However, it should be noted that the experimentally obtained values represent a spatial integration over the entire measurement volume and therefore do not indicate maximum temperature values.

Impact of smoking on oral cavity by comparing carbon monoxide and carboxyhemoglobin levels with salivary pH in smokers of Salem district
Authors: Apoorva S. R. , Jacob Mathew , Fenn Saramma Mathew 
Published: January 2023

Objective:
Saliva is the first biological fluid exposed to the smoke and other contents of the cigar, which can cause structural and functional changes in saliva. Salivary pH is an important biomarker for detecting oral diseases. Cigarette smoke contains many toxic gases, of which, carbon monoxide (CO), plays a deleterious role in causing systemic illness in a person. As a result, a measure of exhaled CO (eCO), similar to exhaled Nitric Oxide, has been evaluated as a potential breath biomarker to detect smoking status and validate smoking cessation to prevent other systemic defects caused by smoking. The present study would investigate the effect of CO and carboxyhemoglobin (HbCO%) on the pH of the oral cavity of individuals with smoked tobacco habit.

Materials and Methods:
For this study, 60 male patients aged 18–55 years with smoking habit of a minimum of two cigarettes or beedis per day for a minimum period of one year reporting to the Department of Oral Medicine and Radiology were divided based on their smoking habit and type of smoked tobacco into two groups with each group consisting of 30 participants. To determine the eCO levels and HbCO% levels, a breath analyzer (piCOTM Smokerlyzer®) was used. Patients were asked to hold their breath for 15 s, place their lips tightly around the mouthpiece of the breath analyzer, and gently exhale through the mouthpiece as long as possible. CO levels in exhaled breath (eCO) in parts per million and HbCO% in the percentage of red blood cells carrying CO (HbCO%) were displayed on the display monitor. A digital pH meter was used to calculate the salivary pH from unstimulated saliva samples. The salivary pH readings, along with the eCO and HbCO%, were recorded in the tabular column for each patient.

Results:
In the present study, the cigarette smokers had a higher mean value of eCO levels. Similarly, cigarette smokers had higher mean HbCo% levels than beedi smokers. It was also observed that salivary pH of smokers was found to be altered when compared to non-smokers.

Conclusion:
The current study found that the level of CO in exhaled breath correlates with the HbCO% present in the blood, alerting tobacco users to the hidden fatality and therefore serving as an indicator in tobacco cessation programs to raise awareness of the effects of smoking on oral health. Furthermore, along with CO levels the pH of saliva was altered, demonstrating the dangers of tobacco and its products.

La verdad fundacional de la biósfera planetaria se encuentra presente y desarrollada en la historicidad de la humanidad por diversas problemáticas que, a nuestra opinión, tienen graves episodios –entre otros- por la crítica y, a veces, perversa visión de una parte exigua de la sociedad que agreden de forma nociva y severa la preservación del planeta, derivando a una inmensa e irracional pobreza, exacerbación en el uso indiscriminado de los recursos naturales (distorsionando el equilibrio dinámico de los ecosistemas), inadecuada y regresiva calidad de vida comunitaria (con la cuestionable afectación de inmensas mayorías en el nivel de vida); asimismo, con insuficiencia extrema de alimentos para un muy extenso y continental sector de la humanidad universal. Es en esta visión pragmática de apreciación, que, nuestra meta es indagar sobre la problemática implicada en el discernimiento y apreciación del saber que nos trae una renovada visión ética, de salud ambiental y -fundamentalmente- de la administración de riesgos (en nuestra opinión: ciencia autónoma), como toda refundación hacia la imperiosa mejora del debido respeto y dignidad humana.

The purpose of this paper is to provide an explanation of the process of making glass gamelan which has recently become a topic of discussion among musicians of the musical arts. Musical art is an intangible form of heritage from historical civilization in the form of chanting music originating from gamelan. In general, gamelan is made of bronze, iron, or brass. So it is different with the gamelan in Song Meri Studio, this studio tries to innovate by introducing gamelan made of glass. This study uses a descriptive analysis method by describing the data from research conducted through field observations, interviews, and collection of video samples uploaded to the You Tube channel. The sample in this study is the Song Meri Studio located in Sukoharjo, Pacitan. The findings show that the birth of the glass gamelan has shattered the enthusiasm of the people in the Nitikan area, Sukoharjo, Pacitan to continue to perform in the midst of the incessant pandemic. By utilizing glass waste as a raw material for making gamelan, Sanggar Song Meri succeeded in attracting public interest and even the regent of Pacitan was inspired to continue to preserve culture even with limited tools. In short, the results of the research that to obtain high and low notes, the effort that can be done is to adjust the length and width of the glass blades, this is of course very different from the way of tuning gamelan within or copper in general.

The human resource management of a company is important in today's competitive business environment because employees are the support of the company. The performance of employees is crucial to the success of any corporation. Therefore, this study aims to identify the factors that contribute to better employee performance (EP). In this study, recruitment, selection, and training strategies are examined for their influence on EP in the UAE public sector, including the construction and related industries. Researchers used a structured questionnaire, a deductive approach, and a survey strategy to conduct the research. In this quantitative study, cross-sectional data was collected using the mono method. A sample size of 151 employees from the UAE public sector was used for this study. SPSS (statistical software) has been used to analyze the collected data. The analysis of the study confirmed a direct positive link between recruitment procedure (RP), effective selection (ES), training, and EP. The outcomes also showed a robust effect of ES on EP. In UAE public-sector corporations, training appears to be the least significant factor influencing EP. Public sector employers, such as construction and related industries in the UAE, should consider the significance and selection of enhanced EP. Doi: 10.28991/CEJ-2022-08-12-012 Full Text: PDF
