محمد علی طاهری، شعور(ط) را به عنوان یکی دیگر از سه عنصر جهان هستی علاوه بر ماده و انرژی معرفی کرده است. انواع مختلفی از میدان‌های شعوری طاهری (TCFs) وجود دارد که مستقیما قابل اندازه‌گیری نیستند، اما، می‌توان اثرات آنها را بر موضوعات مختلفی آزمایش کرد. قبلا، زنده‌مانی و مرگ انواع مختلف رده‌های سلول سرطانی تحت تاثیر TCFs ارزیابی شده است. این آزمایش با هدف تکرار نتایج بدست آمده و همینطور بررسی اثر دو نوع میدان شعوری(ط) ۱ و ۲ بر رفتار مرگ و بقای رده های سلولی Jurkat و LA-N-5 به ترتیب با مورفولوژی لیمفوبلاست و فیبروبلاستی که باعث لوکمی و نوروبلاستوما می‌شوند، طراحی شد. به این ترتیب، بعد از ۴۸ ساعت ، آنالیز چرخه ی سلولی با استفاده از فلوسایتومتری انجام شد. طبق داده‌های بدست آمده میدان شعوری ۱ باعث افزایش معنادار G2/M در Jurkat شد که پیشنهاد کننده‌ی افزایش میتوزاست. در مورد LA-N-5 نتایج نشان داد که میدان شعوری ۲ منجر به افزایش معنادار درصد فاز S شد. این افزایش با کاهش فاز G2/M همراه بود که نشان دهنده ارست فاز S است. اما، میدان شعوری(ط) ۱ تغییر معناداری ایجاد نکرد. این مشاهده، مشخص می‌کند که کاربرد میدان‌های شعوری(ط) مختلف می‌تواند منجر به نتایج متفاوت بشود.
The Word’s Unity of Existence: A Cognitive Science Theory on the Origin of Language and Grammar
Authors: Taheri Mohammad Ali 
Published: September 2023

What is certain is that to begin speaking and expressing themselves, humans did not actually ever sit down to deliberately invent words, grammar, dialects, or manner of speech. So, where did the grammar originate? Did humans first speak, and then discover the grammar, realizing that their speech adhered to precise principles? Or did they first invent the grammar and then began to speak according to grammatical rules? Since humans never intentionally thought about grammar, from the very beginning, they must have begun to speak intuitively and spontaneously in order to communicate their thoughts and intentions. How they used words and sentences to convey their thoughts and intentions is an important subject worth exploring, which we examine within a framework that we call the "the Word’s Unity of Existence." The ability to speak enabled humans to express their thoughts, and they were able to establish communication with each other in a completely different way from other living organisms. Language also allowed humans to connect with, interpret, and make sense of the world around them. It helped them to express their excitement, joy and sorrow, and evolve into an exceptionally unique being. It is expected that in the future, humans will continue to discover more of their abilities, just as they discovered free verse poetry and indulged in its enjoyment and drew out various genres of music from within their nature, and so on. But the question is, have all these abilities been placed in the human existence by chance, or are they part of a highly intelligent design that speaks of an "Innate Universal Unity of Existence”?

The paper tried to determine the impact of higher education and Africa's economic development: challenges for the Nigerian economy. It was observed from the study that high quality and of course market relevant education is capable of providing a genuine cure to economic problems. The paper employed the Solow growth model where on the process to promote economic growth and development, factors of production like capital and labour are employed. However the efficient use of these factors (capital and labour) demands that the workers are well trained and skillful through education. This study assumes a straight forward production function in which changes in output are due to changes in the quantity and quality of inputs, economies of scale and advances in knowledge. The findings of the study suggest that some of the chosen variables conform to theoretical predictions and as such affect economic development. The researcher recommends governments can induce changes in labour demand and supply through specific labour market policies and social protection programmes and offering opportunities for workers to upgrade their skills, and offering education and training at an affordable cost, help raise a corporation's and an economy's productivity and also Educational budget allocation stakeholders should focus more on increasing capital expenditure, recurrent expenditure, and human capital development to foster economic growth in the country.

Background: Abnormal thyroid function tests have been detected at various phases in people living with Human immunodeficiency virus (HIV) and the effect of highly active antiretroviral therapy (HAART) not well understood. However, there is insufficient study among Nigerians living with HIV.
Objective: This study is aimed to determine thyroid hormones in HIV positive individuals compared with HIV negative individuals in Umunze, Anambra State, Nigeria.
Materials and Methods: This cross-sectional study was carried out over a period of six months among 95 HIV positive and 30 HIV negative individuals attending USAID/FHI clinic of Immaculate Heart Hospital in Umunze, Nigeria. The subjects were divided into three groups on the basis of HAART (those on HAART [48] – GROUP 1, HAART naïve [47] – GROUP 2 and Control [30] – GROUP 3). The subjects were interviewed, examined and blood sample collected for determination of thyroid function parameters which include thyroid stimulating hormone (TSH), free triiodothyronine (fT3), triiodothyronine (T3), free thyroxine (fT4), and thyroxine (T4).
Results: Among the 125 subjects recruited for the study 67.2% were females and 32.8% males. The mean levels of TSH and fT3 was found to be higher in group 1 subjects than in group 2 and the group 3 subjects. The mean level of T4 was significantly higher in group 2 subjects than group 1 and the group 3 subjects. The level of T3 was significantly lower in control subjects in comparison to both HAART and non-HAART subjects. Primary hypothyroidism is the commonest pattern of thyroid dysfunction among the HIV positive patients followed by isolated low fT4.
Conclusion: Serum levels of thyroid hormones as shown in this study may be used as baseline periodic markers during antiretroviral therapy while people living with HIV may benefit from supplementation if appropriate. There is also need for a larger study to identify the risk factors for progression to overt thyroid disease in HIV infected subjects with thyroid autoimmunity.

Aims: This study aimed to isolate and characterize thermotolerant phosphate solubilizing bacteria (PSB) for potential agricultural applications. We aimed to identify promising PSB isolates and evaluate their traits.
Study Design: Conducted a comprehensive screening of PSB isolates and selected three top candidates based on their phosphate-solubilizing index. These isolates underwent various tests, including thermotolerance assessment, biochemical profiling, and enzymatic assays. Soluble phosphorus and pH levels were also monitored over time.
Methodology: Screened multiple PSB isolates, selecting PT26, PT31, and PT35. Conducted growth measurements under elevated temperatures, assessed biochemical profiles, and tested the antibiotic susceptibility. Also monitored soluble phosphorus and pH of PSB isolates over 96 hours and measured acid and alkaline phosphatase activities. Molecular identification was done through 16S rRNA gene sequencing.
Results: Among the selected PSB isolates, PT35 showed superior thermotolerance and potassium solubilization capacity, while PT26 exhibited indole-3-acetic acid synthesis ability. Soluble phosphorus levels varied among isolates, affecting pH. Acid and alkaline phosphatase activities differed significantly. Molecular identification confirmed PT26, PT31, and PT35 as Enterobacter cloacae, Klebsiella quasipneumoniae, and Enterobacter bugandensis, respectively.
Conclusion: This study highlights the potential significance of PT35, PT26, and PT31 in agriculture. Their diverse traits and metabolic activities offer adaptability to varying conditions, and thus can benefit soil health and nutrient cycling. These findings contribute to agricultural microbiology research, potentially enhancing sustainable farming practices and soil fertility.

Published: September 2023

The current study described the synthesis of H-ZSM-5 zeolites with hierarchical micro-meso- porosity (HM-ZSM-5-x) via the soft-templating route, employing organosilane surfactant, 3-[(trimethoxysilyl) propyl]octyldimethyl-ammonium chloride, as the mesoporous template. The catalytic performance was examined in the isomerization of o-xylene in a fixed-bed reactor at atmospheric pressure. Many techniques were conducted to characterize the catalysts. The X-ray diffraction (XRD) and Fourier Transform Infra Red (FTIR) results affirmed that all mesoporous zeolites possess the characteristic MFI structure, as well as good crystallinity. The N2 physisorption measurements signified that all HM-ZSM-5-x samples have higher surface areas and pore volumes than the micro-ZSM-5 sample, with the mesopores accounting for the vast majority of the total surface areas and pore volumes of HM-ZSM-5-x samples. Moreover, the mesoporosity of the obtained HM-ZSM-5-x zeolites can be simply tuned via the variation of the amount of TPOAC used. Compared with classical micro-ZSM-5, the HM-ZSM-5-0.15 sample possessed a higher o-xylene conversion and p-xylene yield that was attributed to its remarkable textural characteristics in terms of higher surface area and prevailing mesoporous character that led to a reduced diffusion limitation. Importantly, the catalyst manifested superb operational stability within 50 h, indicating high resistance against deactivation through coke deposition.

Published: September 2023

Abstract

Objectives
Occupational falls are a major problem for older workers, especially those in the tertiary industry. Recently, it has been suggested that frailty is associated with occupational falls, but it is unclear whether this holds true for older workers in the tertiary industry. This study examined the relationship between frailty and occupational falls among older workers in the tertiary industry.

Methods
This was an Internet-based cross-sectional study. We recruited 5000 older workers (age, 60–75 years) employed in the tertiary industry who were registered with an Internet research company. Frailty was assessed using the Frailty Screening Index’s five items, and participants were classified into robust, pre-frailty, or frailty groups. Occupational falls were defined as falls experienced in the past 12 months while at work. The relationship between frailty and occupational falls was analyzed by logistic regression analysis.

Results
It was found that 6.1% of participants had experienced at least one occupational fall in the past 12 months. On the multivariate analysis, the adjusted odds ratio (aOR) for falls was higher with pre-frailty (aOR: 1.95, 95% confidence interval: 1.30–2.94, P = .001) and frailty (aOR: 4.26, 95% confidence interval: 2.74–6.65, P &lt; .001) compared with robust. Similar results were obtained when the outcome was occupational falls with injury.

Conclusion
Our findings suggest that frailty is associated with occupational falls among older workers in tertiary industries. We recommend that employers introduce frailty screening, and consider countermeasures based on the screening results to prevent occupational falls among older workers.

Published: September 2023

AbstractSkyrmions are vortex‐like localized magnetic structures that possess an integer‐valued topological index known as the skyrmion number or topological charge. Skyrmion number determines the topology‐related emergent magnetism, which is highly desirable for advanced storage and computing devices. In order to achieve device functions, it is necessary to manipulate the skyrmion number in confined nanostructured geometries using electrical methods. Here, the reliable current‐controlled operations for manipulating the skyrmion number through reversible topological transformations between skyrmion chains and stripe domains in confined Fe3Sn2 nanostripes are reported. The results of micromagnetic simulations are successful in numerically reproducing the experiments and explaining them through the combined effect of current‐induced Joule heating and magnetic hysteresis. These findings hold the potential to advance the development of topological spintronic devices.

AbstractBitterness elicits unpleasant sensations in humans, which can hinder the acceptance of foods and medication adherence. Therefore, identifying and masking bitter tastes is crucial for developing palatable foods and promoting medication compliance in the food and pharmaceutical industries. To achieve this, employing agonism and antagonism of bitter taste receptors as effective strategies at the molecular level is essential. In this study, a bioelectronic tongue is developed to characterize the agonism and antagonism of bitter taste receptors. The human bitter taste receptors hTAS2R16 and hTAS2R31 are produced using an Escherichia coli expression system and reconstituted into nanodiscs (NDs). Subsequently, hTAS2R16‐ and hTAS2R31‐NDs are immobilized on the surface of graphene field‐effect transistors (FETs) to construct bioelectronic tongues. The developed system sensitively detected the bitter agonists, salicin and saccharin, at concentrations as low as 100 fM, with high selectivity in real‐time. The dose‐dependent curves shifted and K values decreased by the antagonists of hTAS2R16 and hTAS2R31, indicating antagonism‐based masking of bitter taste. Therefore, the developed bioelectronic tongue holds promise for identifying bitter tastes and evaluating the masking of bitterness based on the agonism and antagonism of hTAS2Rs.

AbstractDesigning Sb/carbon composite is an effective strategy to enhance the cycle stability and rate capability of Sb anodes for sodium ion batteries. However, the introduction of carbon often leads to a loss in specific capacity and initial Coulombic efficiency (ICE). In this work, a new perspective is adopted by focusing on improving the “sloping capacity” contribution of carbon (C) in Sb/C composites, rather than solely increasing the platform capacity of Sb as traditionally done. Theoretical predictions indicate that constructing Sb/C composites with high Sb and carbon interfacial areas can provide more Na adsorption sites, thus enhancing the “sloping capacity” of amorphous carbon. Guided by DFT, a rational Sb/C/NSCDs‐2(N) is successfully developed by self‐embedding Sb nanodots into 2D‐amorphous carbon sheets doped with N/S. Sb/C/NSCDs‐2(N) exhibits abundant Sb/carbon interfacial areas and excellent nanoscale effects, demonstrating ideal electrochemical sodium storage performances. Impressively, the Sb/C/NSCDs‐2(N) provides a “sloping capacity” close to 160 mAh g−1. Significantly, owing to the fact that these interfaces and defects are not in direct contact with the electrolyte, the side reaction of electrolyte is effectively inhibited, leading to no decrease of ICE.

Published: September 2023

AbstractCovalent organic polymers (COPs) memristors with multilevel memory behavior in harsh environments and photoelectric regulation are crucial for high‐density storage and high‐efficiency neuromorphic computing. Here, a donor–acceptor (D–A)‐type COP film (Py‐COP‐3), which is initiated by keto–enol tautomerism, is proposed for high‐performance memristors. Satisfactorily, the indium tin oxide (ITO)/Py‐COP‐3/Ag device demonstrates multilevel memory performance, even in high temperatures, acid‐base corrosion, and various organic solvents. Moreover, the performance can be modulated by the photoelectric effect to maintain a great switching behavior. By contrast, Py‐COP‐0, with similar structure and chemical composition to Py‐COP‐3 but without keto–enol tautomerism, exhibits binary storage performance. Further studies unravel that both the formation of conductive filaments and charge transfer within D‐A Py‐COP‐3 film contribute to the resistive switching behavior of memory devices.

AbstractEasy and convenient reading for blinds is of great significance for lowering their learning, entertainment, and communication barrier, and improving their living quality. The general solution is to learn braille, far from satisfying the meet of the blinds’ daily learning and communication. Here, a new‐type conductor/insulator‐identifiable e‐tattoo proximity sensor is developed by simply depositing the circular interdigitated electrodes on organic semiconductor. The discriminable recognition toward conductors and insulators is realized only based on a single e‐tattoo device. The sensors not only enable recognition of the protruding characters like braille based on distance difference, but also enable recognition of the handwriting ink‐brush and pencil graphite characters based on the unique advantage of the sensors in distinguishing conduct and insulator. These results open a new route to realize the material category recognition, provide a user‐friendly way to help the visual impaired effectively reintegrate into society, and broaden the application field of proximity sensors.

AbstractDriving the pseudocapacitive redox intercalation in 2DMXenes with neutral electrolytes is important for safer, more sustainable, and improved electrochemical charge storage. Single transition metal MXenes, such as Ti3C2, have shown great promise for energy storage, owing to their high conductivity and redox activity. Mixed metallic MXenes, such as out‐of‐plane ordered Mo2Ti2C3, have remained underexplored in energy storage because of the absence of redox activity in most of the electrolytes. Simultaneous structural modifications and instigating intercalation pseudocapacitance in neutral electrolytes could be a viable strategy for enhancing their electrochemical properties. Herein, a facile synthesis of partially oxidized Mo2Ti2C3 MXene (PO‐Mo2Ti2C3) exhibiting improved charge storage capability is demonstrated. Optical, structural, and spectroscopic analyses indicate the formation of oxide nanostructures upon thermal oxidation of Mo2Ti2C3 . This leads to an enhanced energy storage capability with remarkably improved cyclability as well as a high Coulombic efficiency in a neutral LiCl electrolyte. This work highlights the importance of structural modifications of MXenes to enhance their charge storage and shows the promise of less explored double transition metal MXenes in energy storage.
