Authors: Alali Amal S. , Alnoghashi Hafedh , Nisar Junaid , ur Rehman Nadeem , Alqarni Faez A.
Published: October 2023

According to Posner’s second theorem, a prime ring is forced to be commutative if a nonzero centralizing derivation exists on it. In this article, we extend this result to prime rings with antiautomorphisms and nonzero skew derivations. Additionally, a case is shown to demonstrate that the restrictions placed on the theorems’ hypothesis were not unnecessary.

In this investigation, using the biogenic approach, Plectranthus vettiveroides root extract was used to synthesize chitosan nanoparticles (P. vettiveroides CNPs). The produced nanoparticles (NPs) were characterized using UV-visible (UV/vis) absorption spectroscopy, Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). The typical absorption peaks in the UV/vis spectra were located around 253 nm. Functional groups were identified in P. vettiveroides CNPs by FTIR. As per SEM analysis, the NPs generated exhibited a spherical shape with an average diameter of 78.01 nm. In addition, the synthesized P. vettiveroides CNPs were examined for antioxidant and antibacterial properties and anticancer activities. They show a strong antioxidant activity compared to butylated hydroxytoluene as a standard antioxidant. P. vettiveroides root extract CNPs demonstrated the most significant zone of inhibition against Klebsiella pneumoniae (22 mm), followed by Escherichia coli (21 mm), Bacillus cereus (19 mm), and Staphylococcus aureus (17 mm). In addition, using MTT assay, anticancer efficacy against KB (oral cancer) cells was studied. The cytotoxic reaction was observed in a dosage-dependent manner. P. vettiveroides CNPs show bioefficacy because of their size and the existence of bioactive compounds, which can enhance antibacterial and anticancer activities by lysing bacterial and cancer cell walls.
Porous metal foam flow field and heat evaluation in PEMFC: A review
Authors: Aly Ayman A. , Abideen Saeed Jalil , Tao Yuning , Madsen Dag Øivind
Published: October 2023

A proton-exchange membrane fuel cell (PEMFC) generates electricity, heat, and water from oxygen and fuel. Hydrogen is recommended as a fuel because it is a renewable fuel when manufactured, for example, by water electrolysis using renewable energy power. Porous metal has excellent characteristics such as controlled permeability, low density, and high porosity. Corrosion is now the most major hurdle to the use of porous metal in PEMFCs, and owing to the porous metal’s complicated internal structure, additional challenges must be addressed in the coating preparation process. As a result, this article figures out how to successfully handle the porous metal corrosion problem in a PEMFC setting, which increases the porous metal utilization in the fuel cell industry. This article also examined the flow field in PEMFC and important characteristics. The influence of flow field in the fuel cell was also investigated.
A seven level fault tolerant hybrid cascaded inverter for renewable energy applications
Authors: Suresh Katta , Jayaram Nakka , Rajesh Jami , Kishore Pulavarthi Satya Venkata
Published: October 2023

The cascaded H-bridge (CHB) inverters are the prominent inverters used for renewable energy applications. Fault-tolerant operation is one of the foremost concerns to safeguard the continuous operation of the system under a fault on semiconductor switches and DC power supplies. A novel hybrid CHB inverter is proposed by adding a seven-level boost SLB module in cascade with the H-bridge modules. The proposed topology ensures the reliable and dynamic operation of the inverter during the occurrence of a fault. In addition to the fault-tolerant capability of the SLB inverter, the proposed design provides the voltage boosting and self-balancing of the switched capacitors. Extensive simulation results at different operating conditions substantiate the concept of the proposed novel fault-tolerant inverter structure. The prototype system is developed in the laboratory and the experimental results validate the proposed system configuration.

Published: October 2023

Unfortunately, eleven of our provinces were severely affected due to two severe
earthquakes that occurred in our country, the Republic of Turkey, on February 6, 2023. As a result, thousands of buildings were destroyed and
tens of thousands of our citizens lost their lives. From past to present,
such disasters have occurred in many parts of our world and will continue to happen. In order to raise awareness for researchers and academicians reading our article, we will give a new definition of convexity in this article,
and we will call it “earthquake convexity”. In this paper, we study some algebraic properties of the earthquake convexity. Then we compare the results obtained with both Hölder, Hölder–İşcan inequalities and power-mean, improved power-mean integral inequalities and show that the results obtained with Hölder–İşcan and improved power-mean inequalities are better than the others.
Some applications to special means of real numbers are also given.
Fast iterative regularization by reusing data
Authors: Vega Cristian , Molinari Cesare , Rosasco Lorenzo , Villa Silvia
Published: October 2023

Discrete inverse problems correspond to solving a system of equations in a stable way with respect to noise in the data. A typical approach to select a meaningful solution is to introduce a regularizer. While for most applications the regularizer is convex, in many cases it is neither smooth nor strongly convex. In this paper, we propose and study two new iterative regularization methods, based on a primal-dual algorithm, to regularize inverse problems efficiently. Our analysis, in the noise free case, provides convergence rates for the Lagrangian and the feasibility gap. In the noisy case, it provides stability bounds and early stopping rules with theoretical guarantees. The main novelty of our work is the exploitation of some a priori knowledge about the solution set: we show that the linear equations determined by the data can be used more than once along the iterations. We discuss various approaches to reuse linear equations that are at the same time consistent with our assumptions and flexible in the implementation. Finally, we illustrate our theoretical findings with numerical simulations for robust sparse recovery and image reconstruction. We confirm the efficiency of the proposed regularization approaches, comparing the results with state-of-the-art methods.

Published: October 2023

Lower-grade glioma (LGG), a prevalent malignant tumor in the central nervous system, requires accurate prediction and treatment to prevent aggressive progression. We aimed to explore the role of disulfidptosis-related genes (DRGs) in LGG, a recently discovered form of programmed cell death characterized by abnormal disulfide accumulation. Leveraging public databases, we analyzed 532 LGG tumor tissues (The Cancer Genome Atlas), 1,157 normal samples (Genotype-Tissue Expression), and 21 LGG tumor samples with 8 paired normal samples (GSE16011). Our research uncovered intricate relationships between DRGs and crucial aspects of LGG, including gene expression, immune response, mutation, drug sensitivity, and functional enrichment. Notably, we identified significant heterogeneity among disulfidptosis sub-clusters and elucidated specific differential gene expression in LGG, with myeloid cell leukemia-1 (MCL1) as a key candidate. Machine learning techniques validated the relevance of MCL1, considering its expression patterns, prognostic value, diagnostic potential, and impact on immune infiltration. Our study offers opportunities and challenges to unravel potential mechanisms underlying LGG prognosis, paving the way for personalized cancer care and innovative immunotherapeutic strategies. By shedding light on DRGs, particularly MCL1, we enhance understanding and management of LGG.
Agricultural history in pastoral society of Mongolia
Authors: Cho Byounghak , Jeong Buyong , Kim Kisun
Published: October 2023

The Mongols originated in Central Asia. They were a pastoral nomadic people, moving across the steppes of Central Asia with their herds of horses. After Mongol empire's invasion of Europe, Western Europeans were exposed to the true size and scope of the Eurasian landmass. They were exposed to different cultures, beliefs, values, attitudes, and institutions. The papacy and Europe were thus forced out of their narrow religious-geographic perspective. They began to realize that they had to deal with and relate to the non-Christian world with its many different peoples, religions, and cultures, as well as agriculture. The Europeans gradually assigned the Mongols and other Asians a permanent place in the natural order of things. After his defeat at Ulan Butung in 1690, the Oirat Khan in Mongol region, Galdan, retreated to Khovd, as a conflict with his nephew prevented him from going to the Jungar Mongols, and poor diplomatic relations with Central Asia blocked the region behind him. After the Khalkha invasion, interactions with the Qing and exchanges with Tibet were limited by Emperor Kangxi, whose economic policy restricted a nomadic economy. The poor pastures and scarce livestock in Khovd forced Galdan to creatively pursue two strategies. First, he asked Russia for military support to occupy Khalkha to solve the poor pasture problem. Second, he promoted agriculture, because it was more productive than nomadism. He recruited the Uyghur Taranqi, who had moved to Yili, and focused his efforts on developing agriculture. Beijiang’s agriculture among the Jungar Mongols was flourishing during the Baatar Hong taiji period. This paper explains the origins and development of agriculture in Western Mongolia and Khovd during the seventeenth century.
THE CONCEPT ON THE TERM OF MONGOLIAN THROAT SINGING
Authors: Lkhaasuren Kherlen
Published: October 2023

Mongolian “throat singing” has been developed in association with life, religion and traditional customs of the Mongols since ancient time. Today, being considered as one of the authentic art of the nation, khoomei finds its significance in academic research of scholars not only from Mongolia, but also from other countries. The preliminary and important subject of the study related to throat singing refers to the origin of term "throat singing", its meaning, and appellation. The Mongols have created and developed their unique culture in the context of their lifestyle, economy, natural environment and their traditional customs for the centuries in their history. Khoomei is definitely an essential part of their culture, and an exceptional category of the nation’s art, which was brought up to the days as the true “Mongolian” piece.
Mongolian and other languages vocabulary interaction
Authors: Davaajav Gundsambuu
Published: October 2023

Many generations of foreign and domestic scholars have paid special attention to the issue of Mongolian words from the languages of the peoples of the East, which have historical and cultural ties with Mongolia. Their works have an important place in the history of Mongolian linguistics. In the 21st century of science and technology, a rich vocabulary of words and terms from European languages such as Greek, Latin, English, French, German, Italian, and Spanish that have had a significant impact on the Mongolian language vocabulary has been identified and summarized from a linguistic point of view. Thus, scholars have focused on the study of words that have entered the Mongolian language from a foreign language, but there is still no comprehensive study of words that have entered the Mongolian language from a foreign language. Therefore, in the framework of the material collected in this article, we have considered the interaction of Mongolian language and vocabulary of these languages with the example of words from Mongolian, Russian, and French into Mongolian, as well as words from Turkish, Russian, and French.
“Singing as a messenger” or on the issue of “words of the apostle”
Authors: Otgon Ts. , Davaajav G.
Published: October 2023

During the long years of historical development, the people of Mongolia have created many beautiful works that are a unique example of spirituality along with material wealth. As diplomatic relations expanded during the Chinggis khaan conquests, ambassadorships became increasingly specialized. The message to be delivered by the messenger was arranged in the form of short poems and sent to the messenger by heart. This is mentioned quite a few times in the “The Secret History of the Mongols”. Although the study of “The Secret History of the Mongols” has been translated into many languages, researches and translations have been carried out, but there is no study of small-form writings and genres in it. It seems that there are many things that have not been noticed in this text, which is the basis for studying the origin and development of mongolian poems and poetry. Therefore, in the future, it is necessary to deeply study the small form of writing and genre in this writing.
Inverse design and optical vortex manipulation for thin-film absorption enhancement
Authors: Bae Munseong , Jo Jaegang , Lee Myunghoo , Kang Joonho , Boriskina Svetlana V. , Chung Haejun
Published: October 2023

Optical vortices (OVs) have rapidly varying spatial phase and optical energy that circulates around points or lines of zero optical intensity. Manipulation of OVs offers innovative approaches for various fields, such as optical sensing, communication, and imaging. In this work, we demonstrate the correlation between OVs and absorption enhancement in two types of structures. First, we introduce a simple planar one-dimensional (1D) structure that manipulates OVs using two coherent light sources. The structure shows a maximum of 6.05-fold absorption gap depending on the presence of OVs. Even a slight difference in the incidence angle can influence the generation/annihilation of OVs, which implies the high sensitivity of angular light detection. Second, we apply inverse design to optimize two-dimensional (2D) perfect ultrathin absorbers. The optimized free-form structure achieves 99.90 % absorptance, and the fabricable grating structure achieves 97.85 % at 775 nm wavelength. To evaluate OV fields and their contribution to achieving absorption enhancement, we introduce a new parameter, OV circularity. The optimized structures generate numerous OVs with a maximum circularity of 95.37 % (free-form) and 96.14 % (grating), superior to our 1D structure. Our study reveals the role of high-circularity localized OVs in optimizing nano-structured absorbers and devices for optical sensing, optical communication, and many other applications.
Numerical study of static pressure on the sonochemistry characteristics of the gas bubble under acoustic excitation
Authors: Lu Chunyuan , Lou Zongyong
Published: October 2023

The extreme environment formed during bubble collapse can cause a series of chemical reactions inside the bubble, and multiple products (i.e., ˙OH, H˙, O, H2, and HO2˙, etc.) are produced, which is called sonochemistry. In this study, a new model is used to predict the sonochemistry characteristics inside an oxygen bubble oscillating in water. The influences of static pressure, ultrasonic frequency, and the equilibrium radius on the temperature inside the bubble and the yields of chemical products are analyzed. The numerical calculation results are obtained during bubble oscillations under a steady state, which is different from the previous studies that focus on the sonochemical characteristics at the bubble collapse. Numerical studies show that with the change in the equilibrium radius, the maximum bubble temperature fluctuates drastically, and the maximum yields of H2 and ˙OH show a Gaussian curve trend. The cavitation activity corresponding to the equilibrium radius depends on the combination of static pressure and ultrasonic frequency.
Numerical and experimental studies on the influence of gas pressure on particle size during gas-assisted extrusion of tubes with embedded antibacterial particles
Authors: Liu Bin , Huang Xingyuan , Ren Shaoyi , Zhang Xiaohui , Chen Shuiquan
Published: October 2023

During the gas-assisted extrusion process of plastic tubes embedded with antibacterial particles, the particles tend to agglomerate. The dispersion effect of these agglomerates using the nozzle-pressure-difference method is significantly influenced by the gas flow state. Therefore, this study establishes the nozzle dispersion model. The gas flow state near the nozzle is simulated and analyzed by using Ansys Fluent software. Gas-assisted extrusion experiments are conducted with different nozzle inlet pressures, and the size distribution of antibacterial particles is observed by using electron microscopy. The simulation results indicate that increasing the nozzle inlet pressure enhances the dispersion effect and expands the effective dispersion area. The experimental results demonstrate that using the nozzle disperses the agglomerates into particles with a diameter of approximately 100 nm. Furthermore, the nanoparticles diameter size decreases with the increase of the inlet pressure, validating the accuracy of the numerical analysis results.
Tomás Saraceno: semiotic regimes of posthuman temporalities
Authors: Charvát Martin
Published: October 2023

Since 2007, Tomás Saraceno has been developing a project that aims to break out of the anthropocentric understanding of communication and coexistence with other animal organisms. In this article, I point out the importance of using modern visualization technologies to analyze and investigate the structure of communication frameworks and their modalities in the animal world, specifically using the example of spiders. The visualization of what is normally invisible to the eye and inaudible to the ear rearticulates the realm of the visible and the audible, which Saraceno then uses for art-critical purposes, with the aim of forming a new type of posthuman attunement to the environment and other animal species. The condition for outlining and articulating Saraceno’s artistic vision is the use of the latest technologies of visualization, which operate on the principle of digital and algorithmic code. They synthesize different planes of affectivity and transform, modulate, and combine the different modes of signs into a single technical-organic complex: they offer new ways of seeing and feeling the world. Thus, hybrid ecology in Saraceno’s case does not imply a return to primordial ways of life, but on the contrary, it forms a semiosphere attuned to a specific plane of consistency that enfolds distinct modes of signs and develops them into an expression of hitherto unsuspected variants of life.

Morenas-Aguilar, MD, Ruiz-Alias, SA, Blanco, AM, Lago-Fuentes, C, García-Pinillos, F, and Pérez-Castilla, A. Does the menstrual cycle impact the maximal neuromuscular capacities of women? An analysis before and after a graded treadmill test to exhaustion.J Strength Cond Res37(11): 2185–2191, 2023. This study explored the effect of the menstrual cycle (MC) on the maximal neuromuscular capacities of the lower-body muscles obtained before and after a graded exercise test conducted on a treadmill to exhaustion. Sixteen physically active women were tested at −11 ± 3, −5 ± 3, and 5 ± 3 days from the luteinizing peak for the early follicular, late follicular, and midluteal phases. In each session, the individualized load-velocity (L-V) relationship variables (load-axis intercept [L0], velocity-axis intercept [v0], and area under the L-V relationship line [Aline]) were obtained before and after a graded exercise test conducted on a treadmill to exhaustion using the 2-point method (3 countermovement jumps with a 0.5-kg barbell and 2 back squats against a load linked to a mean velocity of 0.55 m·second−1). At the beginning of each session, no significant differences were reported forL0(p= 0.726; ES ≤ 0.18),v0(p= 0.202; ES ≤ 0.37), andAline(p= 0.429; ES ≤ 0.30) between the phases. The MC phase × time interaction did not reach statistical significance for any L-V relationship variable (p≥ 0.073). A significant main effect of “time” was observed forL0(p< 0.001; ES = −0.77) andAline(p= 0.002; ES = −0.59) but not forv0(p= 0.487; ES = 0.12). These data suggest that the lower-body maximal neuromuscular capacities obtained before and after a graded treadmill test are not significantly affected by MC, although there is a high variability in the individual response.

Astorino, TA, Robson, T, and McMillan, DW. Classifying intensity domains from arm cycle ergometry differs versus leg cycling ergometry. J Strength Cond Res 37(11): 2192–2199, 2023—This study compared the distribution of exercise intensity domains in response to progressive leg cycle ergometry (LCE) and arm cycle ergometry (ACE). Seventeen active men and women (age and body fat = 26 ± 7 years and 18 ± 3%) initially performed graded exercise on each modality to assess maximal oxygen uptake (V̇o
2max) and peak power output (PPO). Using a randomized crossover design, they subsequently performed moderate intensity continuous exercise consisting of three 15-minute bouts at 20, 40, and 60% PPO on each modality. Gas exchange data (V̇o
2, V̇co
2, and VE), respiratory exchange ratio, heart rate (HR), blood lactate concentration (BLa), and perceptual responses were acquired. Only 2 subjects were classified in the same intensity domains across modalities, with LCE eliciting more subjects exercising at “vigorous” and “near-maximal” intensities than ACE. Time spent above 70 (22 ± 7 vs. 15 ± 8 minutes, d = 1.03) and 80 %HRmax (15 ± 6 vs. 9 ± 6 minutes, d = 1.04) was significantly greater with LCE vs. ACE. Compared with ACE, LCE revealed significantly higher (p < 0.05) peak (94 ± 6 vs. 88 ± 9 %HRmax, d = 0.81) and mean HR (73 ± 6 vs. 66 ± 6 %HRmax, d = 1.20), V̇o
2 (54 ± 5 vs. 50 ± 7 %V̇o
2max, d = 0.68), and BLa (5.5 ± 2.0 vs. 4.7 ± 1.5 mM, d = 0.48). The results exhibit that progressive leg cycling at identical intensities elicits a greater cardiometabolic stimulus than ACE.

Published: October 2023

Mitogen-activated protein kinases (MAPKs) are a group of serine-threonine protein kinases that can be activated by extracellular stimuli. MAPK14 (p38α) affects major disease processes, while inhibition of p38α has been shown to have potential therapeutic effects. Many inhibitors targeting p38α have entered clinical trials but have a long development cycle and severe side effects. We developed a multi-step receptor structure-based virtual screening method to screen potential bioactive molecules from SPECS and our MCDB libraries. Compound 10 was identified as a promising p38α inhibitor that may be used in the treatment of p38αMAPK pathway-related diseases, but corollary studies are warranted.

Published: October 2023

The role of cuproptosis, a newly discovered form of programmed cell death, remains poorly understood in hepatocellular carcinoma (HCC). This study was aimed at constructing a novel cuproptosis model for analyzing the clinical features, mutation characteristics and immune profile of HCC associated with cuproptosis-related genes (CRG), and to analyze the prognostic value of CRGs in HCC. We comprehensively evaluated HCC datasets containing clinicopathological information from The Cancer Genome Atlas and GEO, on the basis of 19 CRGs. The prognostic value of the cuproptosis-related risk score was established. Our results revealed two clusters associated with cuproptosis. Cluster B exhibited pronounced isolated innate immune cell infiltration and poor prognosis, and significant differences in prognosis and immune infiltration were observed between the groups with high and low cuproptosis risk. High copper mortality risk scores were associated with an elevated tumor mutational burden (TMB) and poor prognosis. Our findings suggest that evaluating copper-death subtypes provides insights into CRGs. Moreover, the copper mortality risk score model aids in characterizing prognosis and immune infiltration independently of the TMB.
Fast Feedback Responses to Categorical Sensorimotor Errors That Do Not Indicate Error Magnitude Are Optimized Based on Short- and Long-Term Memory

Published: October 2023

Skilled motor performance depends critically on rapid corrective responses that act to preserve the goal of the movement in the face of perturbations. Although it is well established that the gain of corrective responses elicited while reaching toward objects adapts to different contexts, little is known about the adaptability of corrective responses supporting the manipulation of objects after they are grasped. Here, we investigated the adaptability of the corrective response elicited when an object being lifted is heavier than expected and fails to lift off when predicted. This response involves a monotonic increase in vertical load force triggered, within ∼90 ms, by the absence of expected sensory feedback signaling lift off and terminated when actual lift off occurs. Critically, because the actual weight of the object cannot be directly sensed at the moment the object fails to lift off, any adaptation of the corrective response would have to be based on memory from previous lifts. We show that when humans, including men and women, repeatedly lift an object that on occasional catch trials increases from a baseline weight to a fixed heavier weight, they scale the gain of the response (i.e., the rate of force increase) to the heavier weight within two to three catch trials. We also show that the gain of the response scales, on the first catch trial, with the baseline weight of the object. Thus, the gain of the lifting response can be adapted by both short- and long-term experience. Finally, we demonstrate that this adaptation preserves the efficacy of the response across contexts.

SIGNIFICANCE STATEMENTHere, we present the first investigation of the adaptability of the corrective lifting response elicited when an object is heavier than expected and fails to lift off when predicted. A striking feature of the response, which is driven by a sensory prediction error arising from the absence of expected sensory feedback, is that the magnitude of the error is unknown. That is, the motor system only receives a categorical error indicating that the object is heavier than expected but not its actual weight. Although the error magnitude is not known at the moment the response is elicited, we show that the response can be scaled to predictions of error magnitude based on both recent and long-term memories.
Conciliación paradigmática: la investigación holística
Authors: Arrieta García Emilio José , Pérez Romero Oscar Eliecer , Naranjo Manchego Robin Mario
Published: October 2023

When initiating a study, a researcher is likely to face the dilemma of selecting the paradigm and scientific approach that best suits his or her requirements and, even more so, to know that the available literature emphasizes research within the quantitative, qualitative and mixed paradigms. In contrast, a series of reflections are presented on holistic research based on the assumption that a conciliation or integration of paradigms allows novice researchers to find a valid option for the construction of the methodological framework, especially with regard to the application of appropriate data collection techniques and instruments which, in turn, contribute to the achievement of the objectives initially outlined. It is also relevant to consider within this discussion various contributions made by authors regarding epistemic models and the integrality achieved with holistic research in terms of the approach to events of interest to the researcher, assuming an integrative, explanatory and contextual attitude of the processes, avoiding as much as possible falling into the scientific reductionism that characterizes the paradigms of preference, beyond a simple combination of their characteristic techniques or those usually used in research under the so-called mixed approach.

In the virtual modality, the achievement of meaningful learning is based on the effective use of the different tools offered by the web. The experience presented here describes the results of a good practice aimed at fostering the collaborative work among the students of the Master’s degree in Computer Mediated Learning of the Pontifical Catholic University of Ecuador through the use of multimedia murals generated in different technological tools. It was applied to four courses (subjects) with a total of 226 students belonging to the first and second levels during the years 2021 and 2022. The teaching methodology implemented matches that of the “flipped classroom.” To conclude, it can be stated that the use of these resources turned out to be a great support to the development of the videoclasses because it favors collaborative learning and helps build knowledge on the web.
Rice bran stabilization using autoclave and optimization of crude rice bran oil recovery using ultrasound-assisted extraction
Authors: Pranowo Dodyk , Savira Tsamara Dhany , Sukardi
Published: October 2023

This research aimed to stabilize rice bran to reduce enzymatic reactions and optimize rice bran oil extraction using ultrasound-assisted extraction (UAE). The optimization was performed using response surface methodology (RSM). The results showed that rice bran oil has three primary fatty acids (oleic, linoleic, palmitic). Stabilization of rice bran using an autoclave (121 °C) for 10 min was recommended, with oil yield (14.2%), free fatty acid/FFA (0.41%), and gamma oryzanol (16.1 ppm). The storage significantly affected oil yield and gamma oryzanol but not FFA (p>0.05). The untreated and stabilized rice bran FFA during 18-day storage ranged from 1.33 to 5.73% and 0.41 to 1.12%. This confirmed that stabilization could inactivate lipase enzymes by reducing FFA. The optimization showed that the linear model best explained oil yield, total phenol content (TPC), and antioxidant activity (IC50), while the 2FI model was best fitted for gamma oryzanol. The optimal condition was found for UAE extraction at an amplitude of 90% and a time of 30 min. Verifying optimal conditions resulted in oil yield (13.6%), TPC (44.8 mg GAE/g), IC50 (207.2 ppm), and gamma oryzanol (15.8 ppm). Further in-depth studies are required to investigate using green solvents in the UAE and gamma oryzanol purification.
Discuss The Effect of The Third Organizational Efficiency Theory on Society and Economic Growth Via Depravity Axes Frustration by A Non-Linear Model (Depravity Aspects Benefits)
Authors: Seddek Laila F. , Abed Ahmed M.
Published: October 2023

TBL elements’ prosperity means saving and growth of the Triple bottom line, which are People, Profit, and Planet. Therefore, this work focuses on analyzing the effect of depravity over prosperity via citizen satisfaction level (CSL) and prosperity growth indicator (PGI) through spreading questionnaires addressing the productive and service companies in Egypt. The authors link CSL and PGI with minimizing service time and maximizing income parameters respectively and tracking prosperity via non-collinear productivity growth model with threshold effects. Therefore, argue that depravity resultin administrative, technician, and financial failure, which can be controlled by empirical proposed Automated Governance Self-Management (AGSM). The organizations' productivity has been tracked by the development efficiency index (DEI), which reflects depravity resistance level using smart poka-yoke ( ). The responses to the questionnaires discover that administrative depravity has two faces, one emphasizes its benefit on facilitating and speeding up the procedures, while the other is adverse and reduces the economic growth rate. The authors advocate changing administrative policies from centralization to traceable decentralization backed by delegation and economic liberty via controlling all activities according to time.
Social Media Strategies for Gender Artivism: A Generation of Feminist Spanish Women Illustrator Influencers
Authors: Palomo-Domínguez Isabel , Jiménez-Marín Gloria , Sánchez-Gey Valenzuela Nuria
Published: October 2023

Nowadays, social networks play a central role in communication media. In this scenario, analysing the gender awareness fostered by the influencers is crucial.
The research explores the female representation portrayed by eight Spanish influencers who address the gender approach from graphic communication. All of them are women illustrators, cover topics related to gender, and use similar communication strategies.
The methodology includes three complementary techniques: first, desktop study to compare the illustrators’ profiles; second, content analysis to delve into the topics addressed and their artivism; third, a Delphi method to assess their contribution to promoting gender egalitarian values, in which experts specialising in communication, philosophy, sociology, psychology, and politics participate.
The results show that feminism is a prominent topic in their publications, stimulating a feeling of sisterhood among women, their core target. From a generational perspective, the influence of their message is more significant on millennials and centennials. Conclusions confirm that social media characteristics, artivism, content hybridisation and transmediality enhance their feministic discourse. Future lines of research may focus on identifying other channels and communication strategies more influential for broad target groups, especially men and generations older than millennials, since these external audiences seem crucial to spread gender awareness.
Retrieval, repetition, and retention: unveiling vocabulary acquisition strategies for ESL learners
Authors: Strong Brian
Published: October 2023

This paper explores the practical implementation of retrieval practice techniques for improving English as a Second Language (ESL) vocabulary acquisition. Effective strategies for fostering long-term retention and comprehension of vocabulary are of utmost importance in the field of ESL education. Three key retrieval practice techniques, namely, The Brain Dump, Low-Stakes Quizzes, and Flashcards, were examined, and their advantages, drawbacks, and potential impact on ESL learners were discussed. Additionally, the integration of digital technology with traditional retrieval practice tools is discussed, highlighting the evolving landscape of language learning strategies. This discussion emphasizes the significance of retrieval practice in enhancing ESL vocabulary acquisition, offering educators and learners valuable tools to reinforce memory traces, engage in active recall, and promote metacognition. However, challenges, such as time constraints, test anxiety, and rote memorization, must be carefully considered in their implementation. Overall, this paper provides insights into the practical utilization of retrieval practice techniques, offering educators a nuanced perspective on improving ESL learners' long-term vocabulary retention and comprehension.

Aim. The molecular identification of Pycnoporus sanguineus, a previously morphologically mushroom, was done to see the antibacterial activity against pathogenic bacteria Staphylococcus aureus and Salmonella typhi. Methods. A fragment of the D2 region of 28S rDNA was amplified by PCR, sequenced, and BLAST was performed using the consensus sequence. The maximum identity score was used to build a phylogenetic tree. Agar well diffusion was used to study the antibacterial activity. Results. Sequencing of a 700 base pair PCR amplicon was carried and a 616 base pair of D2 region of large subunit gene was generated. The 100 blast hits on the D2 region of LSU gene showed similarity to Trametes sanguineus voucher PRSC95 (GenBank Accession Number: JN164795.1) based on nucleotide homology and phylogenetic analysis. Antibacterial screening revealed that the crude extract had higher activity on Staphylococcus aureus, with a 3mm to 13mm zone of inhibition and a 100µg minimum inhibitory concentration, compared to Salmonella typhi. Salmonella typhi had a 5 mm to 15 mm zone of inhibition and a 200 µg minimum inhibitory concentration. Conclusion. According to the obtained result, the morphologically identified mushroom Pycnoporus sanguies can be referred to as Trametes sanguine, and it can be used for producinig antibacterial agents.

Ouémé catchment experiences increasing degradation of its natural resources due to anthropogenic pressure. Consequently, most of the agroforestry species as well as the cultural and Indigenous knowledge related to them are facing a very high risk of extinction. The present research aimed to assess the biodiversity of the useful woody species in this area and their cultural importance and then prioritize these woody species for conservation purpose. An ethnobotanical survey was carried out among 411 randomly selected households followed by an ecological survey conducted in 69 random plots of 0.15 ha. Ecological and ethnobotanical parameters were calculated and then analyzed. To determine the local priorities species for conservation, a local conservation priority index (LCPI) was computed for each species. The high value of LCPI for a given species indicates the need for a greater level of attention for conservation and management. Forty-five useful woody species belonging to 21 families dominated by Leguminosae (24.44%) and Anacardiaceae (8.88%) were reported. The forty-five species were categorized in six use categories by the informants: food, medicinal, construction, fuel, veterinary and technology. The most useful species were Elaeis guineensis (UV=0.24), followed by Parkia biglobosa (UV=0.19) and Vitellaria paradoxa (UV=0.18). The prioritization method yielded top ten ranked species: Adansonia digitata, Parkia biglobosa, Pterocarpus erinaceus, Irvingia gabonensis, Milicia excelsa, Tamarindus indica, Vitex doniana, Prosopis africana, Diospyros mespiliformis and Pterocarpus santalinoides.  With the aim of establishing the sustainable management in the catchment, we suggest that more attention be paid to the aforementioned species as part of rehabilitation activities.
Monkeying around Anthropocene: Patterns of human-nonhuman primates’ interactions in Brazil

Published: October 2023

In Anthropocene, approximately 70% of all terrestrial ecosystems are highly modified by human activities and more than a half of all primate’s species in the world are endangered. Here we present results of a systematic review on published articles with an Ethnoprimatology approach, aiming to assess the nationwide pattern and quality of proximity/interaction between human-nonhuman primates in Brazil, a country vulnerable to high deforestation rates while having the highest primate biodiversity in the world. The first article was published 29 years ago and add up to only 36 published articles until present time. Most studies were conducted in Atlantic forest, but higher number and diversity of interactions was described for Amazon. Sapajus, being a generalist and semi-terrestrial primate, was the most cited genus and had the greatest diversity of interactions, including garbage foraging and crop-raiding. Alouatta, the second most cite one, had more symbolic/mystic relationships. Some specialized or forest-specific primates are scarcely mentioned. Studies carried out in both rural and urban environment are almost equal in number but showed differences in types of interactions they describe: garbage foraging, crop-raiding by primates and food offering by humans happening in more urbanized areas and symbolic/mystic relationships and beliefs around nonhuman primates described in rural/indigenous settlements. We urge future studies to describe interactions and proximity carefully specifying the context where they occur. It is relevant to maintain the growing curve of Ethnoprimatological studies in Brazil as a way to aggregate information about different populations of species and help to base conservation strategies of co-existence.
Diverging Paths

During the Early Bronze Age (EBA), a relatively small number of European societies developed into highly centralised and hierarchical political entities. In contrast to the intensive research focused on these groups, little attention has been paid to their relationship with neighbouring populations, which had a much more egalitarian structure. In the southeast quadrant of the Iberian Peninsula, over a century of research on the EBA (ca. 2200 –1550 BC) communities has failed to identify distinctive traits leading to the definition of archaeological entities beyond the El Argar group, which according to many authors reached the form of an early state organisation around 1750 BC. This study aims to go beyond previous culturalist approaches and to focus on how communities with very different social organisations interacted in this macro-region as well as in a border region between El Argar and La Mancha. To that effect, we analyse primarily settlement size as an expression of the demographic and economic strength of a community, and ‘enrockment’ (enrocamiento), a concept that defines the degree of protection and spatial distancing of a settlement from its surrounding land and neighbouring communities. This large-scale comparative approach reveals the distinctiveness of highly dispersed and well-protected communities settling in the belt immediately north of El Argar and shows how this cost-intensive strategy changes with increasing distance from El Argar, when flat land and often larger settlements become dominant. The combination of settlement patterns and economic organisation also highlights the marked differences between El Argar and all the other communities living in the Iberian Peninsula.

Introdução: Inúmeros estudos têm demonstrado forte relação entre obesidade e doenças psiquiátricas, especialmente doenças do humor. Contudo, poucos avaliaram a correlação entre obesidade mórbida e temperamento afetivo. Objetivo: Estudar a existência de temperamento afetivo em obesos mórbidos antes do tratamento cirúrgico da obesidade. Métodos: O material para leitura e análise foi selecionado a partir de pesquisa em plataformas virtuais com foco nos temperamentos afetivos (hipertimia, distimia e ciclotimia). Inicialmente foi realizada busca por descritores relacionados ao tema (temperamento, obesidade mórbida, cirurgia bariátrica, transtornos do humor” e seus equivalentes em inglês com busca AND ou OR), considerando o título e/ou resumo, e a seguir a leitura do trabalho na íntegra. Resultados: As comorbidades psiquiátricas mais frequentes no sobrepeso e obesidade foram os transtornos do humor, de ansiedade e da compulsão alimentar. A prevalência estimada de temperamentos afetivos em obesos mórbidos é cerca de 65%. Conclusão: A prevalência de temperamentos afetivos é maior em obesos mórbidos, candidatos a cirurgia bariátrica, em comparação a população geral. O temperamento ciclotímico é o mais comum na população de pacientes com obesidade mórbida.
