Published: March 2023

The aim of this study is to investigate the effects of the determinants of basic needs on the motivation of work participation in economic development and life satisfaction. In order to carry out this research, a detailed survey was conducted. Data were collected from 454 households in the city of Can Tho, Vietnam, and were analyzed using the partial least squares (PLS) technique. The findings indicated that the needs of existence, growth, relatedness, and association participation positively influenced work participation in economic development, while the needs for existence and growth positively affected life satisfaction. A significant relationship was also found between work participation in economic development and life satisfaction. The research scope was not limited to poor women but was extended to all residents living in poverty. These results are sources to gain a clear understanding of the desire of the poor for appropriate policies to be implemented for them to escape from poverty and enjoy a higher standard of living. This would help boost the local economy and achieve sustainable goals. The study extends the literature of life satisfaction with motivational theory by identifying factors that affects life satisfaction.

Authors: Saad AbdelGawad , Ali Elsayed , El-Didamony Mohamed , Azam Mostafa
Published: March 2023

Strawberries have a relatively short postharvest life due to their quick softening and decay. When the supply chain is too far along to make logistical adjustments to meet shelf life, quality loss and shelf-life reduction often accelerates with rising temperature. The purpose of this study is to use kinetic modelling to explain how characteristics of strawberry quality vary while they are being stored. To measure the qualities of redness (a*), lightness (L*), chroma colour (C*), weight loss (WL), total soluble solids (TSS), titratable acidity (TA), and total phenolic content (TPC), fresh strawberries were obtained from a farm and stored for 8 days at 4°C and 10°C. The experimental results showed that strawberry quality characteristics stored at 10 °C had a strong and significant impact. After being stored at 10°C, the properties of redness (a*) and lightness (L*) quickly converted to darker zone. During storage at 10 °C, a significant rise in weight loss and chroma was seen with a less apparent decrease in L*. Zero-order and first-order models are used to characterize quality changes that occur during storage. The WL, TSS, and TA properties were best described by the zero-order model. On the contrary, the hue change was described by the first-order model. The results demonstrate that kinetic models fall short in their ability to characterize changes in TPC property during storage. In comparison to strawberries stored at 10°C, the strawberries stored at 4°C carried out the desired result of weight loss, colour change, and TA change.

Published: March 2023

Bachground: In recent years, problems related to environmental damage and natural resource degradation are receiving increased attention from researchers throughout the world. This occurs mostly, through un-eco-friendly technology used to produce industrial products. Therefore, eco-friendly science and technology (green technology) which can empower and control the existing coal power plant for the virtue of society and the earth is required. Today, the design and application of electron accelerator has been well developed due to reliability, larger capacity, greater energy range, and cost reduction. Technologies that use particle accelerators are considered critical to advance high-tech processes in various economic fields, including material processing, sterilization of medical products, environmental protection, medicine, cargo inspection, chemical analysis, nuclear energy, etc. High-energy and high-power beams pose the ability to alter the physical, chemical, and biological properties of materials on an industrial scale. This technology has received more attention than other conventional treatment methods due to the need for smaller areas, high electrical efficiency, and production of by-products such as fertilizers. The electronic beam process in the treatment of off-gas, wastewater, and sludge, as well as the decomposition of emerging contaminants, is mentioned as a non-chemical, additive-free process that uses radiolysis to effectively decompose contaminants. The literature addresses various applications of electron accelerators in order to modify the physical, chemical, or biological properties of industrial pollutants in the liquid, solid, and gas phases through treatment by ionizing radiation to control environmental pollution. Many advantages can be achieved through this method, which is known as radiation processing.

Published: March 2023

Background and aim: Exposure to noise causes auditory and psychological effects in humans. Among the sources of sound generation are the means of transportation, which can cause anger and aggression. The present study was conducted with the aim of investigating the relationship between living in different places in terms of traffic and noise sensitivity with aggression in housewives in Yazd city.
Method: This was a cross-sectional study conducted in 2019-2020 among housewives in Yazd city. First, the city of Yazd was divided into three areas with high, medium and low traffic using GIS software, and 100 people from each area, were included in the study in a stratified random manner. Information was collected using Weinstein's bass and Perry questionnaires and sensitivity to sound. Finally, the data was statistically analyzed using SPSS version 24 and R version 4.0.2.
Findings: Findings revealed that those who lived in high traffic have a higher aggression score (P-Value=0.009), while no significant difference was observed in the noise sensitivity score among people of different groups (P value=0.071). In addition, a direct and significant relationship was observed between aggression and sensitivity to sound (r=0.28 and P value<0.001). Only two variables of noise sensitivity and place of residence were included in the regression model and (R Square) was equal to 0.096.
Conclusion: The results showed that the two factors of traffic load and noise sensitivity have a direct and significant relationship with aggression score among housewives in Yazd city. It is also suggested to use different sound insulation and barriers in buildings.
Gradient Bending Model of Inhomogeneous Piezoelectric Beam
Authors: Vatulyan Alexander О. , Nesterov Sergey A.
Published: March 2023

The problem of bending a horizontally inhomogeneous piezoelectric cantilever beam is studied taking into account scale effects. The lower and upper surfaces of the beam are electroplated. Three types of loading are considered: load uniformly distributed along the length; transverse force at the other end of the beam; supply of electric potential to the upper electrode. The beam bending is modeled based on the Euler-Bernoulli hypotheses and the quadratic distribution of the electric potential. Based on the application of the variational principle of gradient electroelasticity, a system of differential equations of bending and electrostatics is obtained, as well as an extended range of boundary conditions. To find the bending moment and deflection of the middle line of a homogeneous beam, exact analytical expressions are obtained. In the case of an inhomogeneous beam at large values of the scale parameter, the solution is based on the shooting method. On specific examples, the calculations of moments and deflection are carried out, both in the case of a homogeneous and inhomogeneous beam. The influence of the mechanical and electrostatic gradient parameters, the electromechanical coupling coefficient, and the inhomogeneity parameter on the distribution of deflections has been clarified.

Authors: Beshtokov Murat Kh.
Published: March 2023

We study a boundary value problem for a loaded moisture transfer equation with two Gerasimov - Caputo fractional derivatives of different orders (α, β), variable coefficients, and a nonlocal integral boundary condition. On a uniform grid a difference scheme of order of approximation 𝑂(ℎ2 + 𝜏2) for 𝛼 = 𝛽 and 𝑂(ℎ2 + 𝜏2−𝑚𝑎𝑥⁡{𝛼,𝛽}) for 𝛼 ≠ 𝛽 is constructed. The study is carried out by the method of energy inequalities. For different ratios between the orders of fractional derivatives α and β, for solving the posed nonlocal boundary value problem, a priori estimates in the difference interpretation are obtained, from which the uniqueness of the solution of the posed problem, the continuous and uniform dependence of the solution on the input data, and the conv ergence of the solution of the difference problem to the solution of the original differential problem at a rate equal to the order of approximation of the difference scheme.
Effective Method for Constructing Amplitude-Frequency Shell Characteristics
Authors: Yudin Anatoly S.
Published: March 2023

Timoshenko type equations are used, taking into account the transverse shift. The shell has the properties of constructive anisotropy. Forced oscillations in the frequency range, including the first significant low-frequency resonances, are considered. The internal scattering of vibrational energy is taken into account by the method of complex amplitudes. The influence of a number of parameters on the amplitude-frequency characteristics (frequency response) of input compliance is investigated. A semi-analytical method of constructing a solution is used. In the case of a cylindrical shell freely supported at the ends, Fourier series are used in two coordinates. The problem of forced oscillations is solved by decomposing the amplitudes of displacements according to their own forms of oscillations. At the same time, the separation of equations for determining coefficients by harmonic numbers is provided. The algorithm on this basis allows you to quickly build the amplitudefrequency characteristics necessary for analysis.

The present study adopts a quantitative and cross-sectional approach. The sample included 129 university professors, between 18 and 74 years, from the Faculty of Physical Culture Sciences of the Autonomous University of Chihuahua. Satisfaction with Life Scale (SWLS) was obtained to measure the degree of teacher satisfaction (Atienza et al., 2000; Diener et al., 1985; Pons et al., 2002). The results globally showed significant differences between life satisfaction before and during the pandemic according to the means comparison test, using the T-test for related samples, with values ​​of 4.06 before and 3.6 during the pandemic. When categorizing the results according to the escalation, it was shown that 55.7% of the teachers perceived themselves as satisfied before the pandemic, while the opposite happened during the isolation, decreasing, with only 45.5% feeling satisfied. Only 27% felt very satisfied before, and this percentage decreased to only 14.5% during isolation. The  COVID-19 not only wreaked havoc on health, but it also had a negative effects on people's psychological, emotional, and social spheres, thereby modifying healthy lifestyles and leaving possible effects on physical and mental health as a consequence.

Land mines detection, mapping and clearance using Quadcopter in Yemen: A perspective study
Authors: Alwatiri Shawqi , Omar Zakarya , Algabri Yousif A.
Published: March 2023

People who live or work in areas where there have been armed conflicts may face the threat of landmines and explosive hazards, such as unexploded or abandoned ordnance, abandoned military vehicles, and equipment. Therefore, this is a tremendous obstacle to development and construction in such areas, which requires awareness of the threat and appropriate preventive action. This paper aims to facilitate the detection and elimination of planted landmines in Yemen. Two stages are proposed to be implemented in this study for the demining techniques: detection and clearance phases. The first phase uses a Quadcopter with detecting sensors to locate and map the mines' spot, while the second stage uses a Quadcopter to unload a mass on that determined location from a certain height. By employing these two stages, it is expected to quickly and accurately detect the locations of landmines. That will reduce risk, protect human lives, and provide a more efficient and safe way to sweep minefield workers using sample, small, and easy control equipment.

Published: March 2023

Healthy growth and development of children is the right of every child, both physically and mentally. Stunting is one of the features of delayed growth and development as a result of chronic malnutrition. The purpose of this study was to see the association maternal feeding patterns and quality of food consumption on stunting in children aged 18-24 months in Bogor City. This study uses a nested case-control study design by analyzing data from a cohort study of child development in five villages in Bogor. A total of 90 subjects aged 18-24 months were selected in this study consisted of 45 stunting subjects and 45 non-stunting subjects. The variables analyzed in this study maternal feeding patterns and quality of food consumption as measured by the energy density and other nutrients. Chi-square test was used to analyze the data. The results showed that there was a significant relationship between maternal feeding patterns (p=0.002) and stunting in children aged 18-24 months. There was a significant relationship between iron density measurement 2 (p=0.017) and calcium density measurement 2 (p=0.004) and stunting in children aged 18-24 months. Energy density and protein density did not show a significant relationship with stunting. Poor food parenting, as well as low intake of iron and calcium can increase the occurrence of stunting in children aged 18-24 months.
Forging Fraught Solidarities: Friendship and Feminist Activism in South Asia
Authors: Kanagasabai Nithila , Phadke Shilpa
Published: March 2023

Friendship has been central to the forging of feminist solidarities. Cross-border friendships and feminist activism in South Asia have disrupted narratives of violence and hostility between countries. Friendship then is deeply political for multiple reasons, often facilitating a powerful critique and unsettling hegemonic, heteropatriarchal narratives of affective relationships. Drawing on the narratives of feminist activists in South Asia, we explore the nuances of ‘doing activism’ with friends as well as how friendship itself inflects activism and the interrogations that these might bring to the fore. We reflect on the ways in which feminist activism has engaged with fun arguing that joy is intrinsic to feminist organising. We also examine feminist fractures and how these might impact our activism, our friendships, and what they reveal about structural inequalities. As we reflect on the transformative potential of feminist activism within the South Asian region over the last four decades and the friendships it has nurtured, we ask if friendship has fulfilled the promise of challenging existing structural hierarchies and reimagining our relationships, concluding that the answer must be yes and no.
Shaheen Bagh and the Politics of Protest in the Anti-CAA Movement in India
Authors: Sharma Yash , Singh Shatakshi
Published: March 2023

This article attempts to understand the pathways and politics of resistance within the anti-CAA/NRC (Citizenship Amendment Act/National Register of Citizenship) protests in India. Led and organised by Muslim women, the activists living in the locality of Shaheen Bagh emerged as a powerful symbol of resistance against, and reimagination of, hegemonic notions of nationalism, secularism, citizenship, and belonging in contemporary India. By exploring the resistance seen in Shaheen Bagh as a case study, our analysis tries to understand the ways in which the protest was a reflection of emergent solidarity, engendered in part by the communalisation of everyday life in India and the rise of Hindu majoritarianism. We contend that the actions in Shaheen Bagh should be seen as symbolising an organic resistance movement located at the intersection of gender and religion. This research aims to raise the following questions: How did the activists from Shaheen Bagh navigate its potential as a gender-based protest movement while framing a political opposition to CAA/NRC? How does the idea of Shaheen Bagh offer us new vocabularies of thinking about alternative democratic futures through the prism of prefigurative politics? This article suggests we need to resist a linear or coherent reading of the protest and instead attend to its fragmentary, contested, and contradictory forms.

Louis Armstrong’s Lip Problems: Satchmo’s Syndrome Reviewed
Authors: Rosset-Llobet Jaume , Rosset-Garric Queralt , Grimalt Ramon
Published: March 2023

Rupture of the orbicularis muscle of the lips in wind musicians is known as Satchmo’s syndrome because it is assumed that Louis Armstrong (nicknamed Satchmo) suffered this condition. But whether Louis Armstrong really had this problem or not has never been documented. AIMS: This
study is a biographical review and an analysis of the existing photographs of Armstrong’s lip with the aim of better understanding the origin and progression of his disorder. METHODS: A review was made of the most important biographies, newspapers, and magazines referring to Louis Armstrong
and med¬ical reports about Satchmo’s syndrome. Major archives related to Louis Armstrong were searched for documents, photographs, articles, videos, letters, and other items, using the terms “lip,” “embouchure,” “mouth,” and “problem.”
Information was sought on Armstrong’s playing technique, playing schedule, lip changes, lip problems, and other related health issues. RESULTS: It was found that Louis Armstrong suffered dermatological lip problems due to his intense playing schedule and the way he played from the very
beginning of his career. This first created swelling and superficial erosions that later became cracks and fissures. These lesions finally produced ulcers which evolved into scar tissue after healing. This made the mucosa thicker and stiffer, making it more difficult for the lip to vibrate
and forcing him to increase the tension and pressure in the area in order to play the trumpet. This created a vicious cycle with the scar tissue leading to further problems. These injuries even bled several times while he was playing and, on some occasions, left his mouth and clothes bloodied
in the middle of concerts. His biography does not make any reference to difficulties or symptoms that could indicate that he had orbicularis oris muscle rupture, except for the fact that he had trouble playing, a symptom common to any injury to the lips in a wind instrument player. CONCLUSION:
Analysis of the existing data indicates that Louis Armstrong’s lip problems were most likely due to mucosa fibromatous hyperplasia resulting from chronic microtrauma rather than a rupture of the orbicularis oris muscle. Therefore, we propose that this disorder should no longer be referred
to as Satchmo’s syndrome.

Authors: Zahn R , Schmidt M , Wallner A , Fischer T , Ohlendorf D , Wanke EM
Published: March 2023

OBJECTIVE: The feet of professional dancers are exposed to high work-related stresses. To date, data from the professional dance sector concerning this matter are lacking. The aim of this exploratory project was to analyze and evaluate skin health in the foot area with regard to the
prevalence of dermatoses, their locations, as well as gender-specific and load-specific differences. METHODS: Professional classical and neo-classical ballet dancers were examined at two time points: in a phase with increased stress (T0: daily training sessions, rehearsals, and high performance
frequency) (n=51, 35 females, 16 males) and after a 24-day rest phase (T1: n=35, 28 females, 7 males). In addition, gender-specific and load-specific (T0 and T1) differences were evaluated. RESULTS: All professional dancers were affected by skin lesions of the feet at T0. Hyperkeratosis (96.1%),
onychomycosis (27.5%), and subungual hematoma (11.8%) were the most frequent dermatoses of the feet of professional dancers. Onychomycosis affected the nails of the big toes in particular (right 15.7%; left 13.7%), and subungual hematomas were found exclusively on the nails of the first toe
(right 7.8%; left 7.8%). Women tended to be more frequently affected by hyperkeratosis, men more frequently by onychomycosis. There were no load-specific differences between the stress and rest phases. CONCLUSION: The prevalence of work-related dermatoses is equally high among female and male
dancers. The results can be used for further research and serve as a basis for specific measures of behavioral and environmental prevention in dance.

Published: March 2023

OBJECTIVE: Dexterity is one of the abilities required for different types of work and is divided into manual and finger dexterity. The aim of this study was to examine whether there was a difference in manual and finger dexterity between musicians and nonmusicians, and between musicians
divided by instrument groups and nonmusicians. METHODS: The study included 128 participants (96 musicians, 32 nonmusicians). Musicians were divided into three groups as wind, string, and keyboard instrument players. The Minnesota Manual Dexterity Test (MMDT) for manual dexterity and Purdue
Pegboard Test (PPT) for finger dexterity were used. Independent samples t-test and Mann-Whitney U test were used for MMDT, and the Mann-Whitney U test was used for PPT between musicians and nonmusicians. The Kruskal-Wallis H test and one-way ANOVA were used for comparisons of the MMDT and
PPT between nonmusicians and musicians divided by instrument groups. RESULTS: There were no differences between musicians and nonmusicians in terms of MMDT and PPT (p>0.05). When musicians were divided by instrument groups, there was a statistically significant difference in only the left-hand
subtest of PPT (p=0.038). In pairwise comparisons, significant differences were found between wind and string instrument players (p=0.036), keyboard and string players (p=0.012), and nonmusicians and string players (p=0.015). Wind and keyboard players and nonmusicians were more successful
than string players in terms of left-hand finger dexterity. CONCLUSION: Future studies can be designed that investigate the effects of bilateral asymmetrical-symmetrical training on finger dexterity of the left hand and evaluate the performances of musicians in areas other than music.

The aim of this study is to provide an overview of various models to study drug diffusion for a sustained period into and within the human body. Emphasized the mathematical compartment models using fractional derivative (Caputo model) approach to investigate the change in sustained drug concentration in different compartments of the human body system through the oral route or the intravenous route. Law of mass action, first-order kinetics, and Fick's perfusion principle were used to develop mathematical compartment models representing sustained drug diffusion throughout the human body. To adequately predict the sustained drug diffusion into various compartments of the human body, consider fractional derivative (Caputo model) to investigate the rate of concentration changing depending upon the change in the order of fractional differentiation in all the possible compartments of the body, i.e., systemic circulation and tissue compartments. Also, assigned a numerical parameter value to the rate of drug flow in different compartments to estimate the drug concentration. Results were calculated and figures were depicted by using MATLAB software (version R2020a). Illustrated graphical effects of change in concentration rate by assuming various intermediate values according to the fractional derivative (Caputo model). The resultant graphical representation concludes that considering the order of the differential equation values, the drug concentration varies depending upon its rate of constants in compartments concerning time. Considering the initial case for rough estimation where the body is indicated as a whole compartment, following division of the body into two model compartments. Whereas, the model I represents stomach, liver, and systemic blood, and model II consider arterial blood, liver tissue, and venous blood.

Let G be a graph with p vertices and q edges and  be an injective function, where k is a positive integer. If the induced edge labeling   defined by for each is a bijection, then the labeling f is called an odd Fibonacci edge irregular labeling of G. A graph which admits an odd Fibonacci edge irregular labeling is called an odd Fibonacci edge irregular graph. The odd Fibonacci edge irregularity strength ofes(G) is the minimum k for which G admits an odd Fibonacci edge irregular labeling. In this paper, the odd Fibonacci edge irregularity strength for some subdivision graphs and graphs obtained from vertex identification is determined.

Placing a flow tube on the wellhead to suction flame during a well control operation is key to creating a safe environment near the wellhead. Aiming at the problem that the internal flame of the flow tube can easily leak during the rescue of a high-pressure gas well, we propose in this paper to use the self-excited negative pressure effect to improve the capacity to suction flame. Based on the coupling method of the Reynolds averaged Navier-Stokes equation and mixed combustion model, a gas well combustion model is established. The accuracy of the model is verified by proportional scaling experiment. Furthermore, the sensitivity analysis of key structural parameters of self-excited negative pressure flow tube is carried out, and the structure of the flow tube optimized. The result shows that the optimized flow tube has a suction flow about twice that of the horn flow tube, and the suction scope is increased by 61.5%, which greatly improves the flame suction capacity. The research work can provide guidance for structural design and optimization under self-excited negative pressure effect.

Generally, Brushless DC (BLDC) machines attract many industrialists due to their unique characteristics like better output, stabilized performance, and high torque to current ratio. BLDC drive has a long life, and they do not need maintenance; however, the drive has low starting torque and high cost. Thus, Non-stop monitoring and future prediction methods can reduce fault occurrence and improve system performance. In this paper, we have proposed the prognosis of BLDC drive faults using the Autoregressive Integrated Moving Average (ARIMA) Algorithm. Here, we consider the open circuit (OC) and short circuit (SC) faults in BLDC drive to prognosis by ARIMA technique. The ARIMA has a fixed structure, and it is particularly built for time series data. By data acquisition system, the drive parameters such as current, torque, and speed will be continuously obtained. Filtering out the high-frequency noise present in the data is the main principle of the ARIMA model. Matlab/Simulink platform is used to implement the process and analyze the results using prediction efficiency, the fault analysis in speed, flux, torque, current, and voltage.

Due to the population growth of the organisms at an unpredicted rate, biological sequence data generation keeps on increasing day by day. Rapid technological development leads to the improved version of sequencing machines which makes it to generate massive amount of Genome sequences much easier than before. Biologists engaged in large Genome projects sequenced huge amount of Genome sequences for different organisms and stored in the biological databases everyday which results in data storage crisis in the field of Bioinformatics. Handling of huge volume of Genome data creates a challenge in storage, analysis and transmission. Compression of Genome sequence data is essential to address this challenge. In this paper, a simple but effective compression algorithm for Genome sequences namely DNA Digital Dictionary (D3) is proposed using an efficient encoding scheme for better compression. The proposed algorithm is demonstrated using Genome sequences of different organisms. Experimental results of the proposed algorithm are compared with the state of art tools and recent existing algorithms. It is observed that the proposed algorithm “D3” outperforms the existing methods in terms of compression ratio and compression time. The average compression ratio for the proposed technique is 4:1 and the time complexity is O(n).

Published: March 2023

Wireless Sensor Network (WSNs) plays a vital role in smart grid (SG) environment. Due to the fault tolerance characteristics, cost reduction and large scale convergence. SG introduce many unique challenges caused by system and functional devices. To solve this problem, a WSN based SG network is used for identifying faults. During the process of data transmission, faulty nodes are occurred in the transmission line. Due to the nodes failures, calibration, network failures, low battery, dried sensors, environmental changes and software failures etc., which leads to the interruption in data delivery and spoil the entire WSN based SG network. In order to tackle these problems, the new WSN model is designed to detect the faults in the transmission line based on the SG environment. In this paper, Adaptive Zigbee-Aquila communication protocol (AZACP) is used to find the optimal shortest path for transferring data. AZACP finds the shortest optimal path for transmitting the sensed data to base station with low cost and less time consumption. Fault detection is the process of automatically identifying the fault in the transmission line and isolate the faulty nodes to ensure the efficient data transmission in WSN. Here, Enhanced Recurrent Equilibrium Neural Network (ERENN) is introduced to identify the fault in data transmission. It recognize the strength of the signal to transmit the sensed data and checks the quality of the data in transmission line between the nodes. The proposed approach is implemented in MATLAB software and compared with existing approaches like Adaptive Error Control (AEC), Gallager Humble Spira (GHS), Genetic Algorithm-Ticket Based Routing (GA-TBR), Improved Grid based Routing and Charging (IGRC) and Emperor Penguin Optimized Self-healing Strategy (EPOSH). The proposed approach provides better performance in terms of evaluating performance metrics like throughput, delay, reliability, average residual energy, number of total transmission, network lifetime, efficiency and Bit Error Rate (BER).
