Authors: Alkadasi Dr. Nabil Abdullah Noman 
Published: July 2023

Effect of treatment of mono-alkoxy pyrophophato coupling agent on mechanical properties of composites made from High Density Polyethylene and Magnesium hydroxide is reported here. The coupling agent in the form of solution (1.5%) was used for treatment of the filler. The treatment resulted in enhancement of mechanical properties of composites when compared with composites containing untreated Magnesium hydroxide. The properties under consideration were tensile strength, modulus at (%) elongation at break, elastic modulus, hardness, etc. Although good reinforcement was observed due to treatment of 1.5% coupling agent, observed was very much remarkable to compared to untreated one. Comparison of properties of composites filled with treated and untreated Magnesium hydroxide established that treatment of Magnesium hydroxide imparts better reinforcing properties. The properties under consideration were tensile strength, (%) elongation at break, elastic modulus, hardness, etc. Tensile strength was improved by 21.43%, elastic modulus was improved by 71.53%, while hardness was improved by 1.01%, at (0.37) volume fraction.

Impact of ICT Resources on Addressing Listening Comprehension Needs of ESL Learners
Authors: R SreeRekha 
Published: July 2023

The benefit of digital technology is all around us and has significantly contributed to English language learning (ELL) practices. The English language proficiency of the second language learners has always been a matter of great concern. Of the four language skills, listening the fundamental skill, remains as one of the most neglected skills in classroom activities. The existing language teaching system in Kerala pays little attention to develop it. When listening comprehension (LC) of the learner is not given the right opportunity to develop it that will lead to poor language proficiency. The focus of this paper is to analyse the listening comprehension needs of English as a second language (ESL) learners in Kerala and to suggest how ICT resources can be used to address them. The paper concludes with the finding that if integrated judiciously and used appropriately, ICT resources can play a great role in developing the language proficiency and Listening comprehension of second language learners.
The Diary an English Teacher Did Not Keep
Authors: B Hariharan 
Published: July 2023

Let me begin with a disclaimer. I am not very sure whether disclaimers are permitted in a volume of scholarly papers. And yet, disclaimers have a way of getting into the lived experience of some academicians, especially those who teach language and literature. We get to listen to unspoken disclaimers from students in the English language classroom, for example, when we ask questions. The unspoken has a particular narrative force for it puts our question under erasure. The disclaimer is written over in the language teacher’s classroom. There are different kinds of disclaimers like the one I make when I say that I am not an ELT specialist. It is quite possible to explain the potential of disclaimers and invest them with meaning. I build my disclaimer on the claim that I am not a language specialist in that sense and I do not have any formal training in the teaching and learning of English. My disclaimer that I am not an English Language Teaching specialist rests, perhaps paradoxically, on the claim that I am an English teacher. Disclaimers sometimes are followed by confessions. I never studied ELT or even ESP for that matter. I am aware of the possibility that my disclaimer could find some space alongside the disquisitions of those colleagues trained in ELT and ESP.
Role of Linguistics in Language Teaching
Authors: Shanavas Prof S.A. 
Published: July 2023

Linguists identify the distinctive features of language which make language stands apart from other means of communication. Linguists and Applied Linguists argue that language teachers should be aware of the linguistic theories formulated by both theoretical linguists and applied linguists. Language teachers act as communicators, educators, evaluators and agents of socialization. An awareness of the rules of linguistic theories places them ahead and the transaction process gets facilitated. This paper presents the role of Theoretical Linguists and Applied Linguists in theoretical formulations for language teachings. The paper also examines the theories of language acquisition. There have been discussions at the various levels about the role of linguistics in language teaching in the area of communication, in the inculcation of speaking skills and when the language teacher becomes educator, evaluator and agent of socialization.

This paper reports on the viscosity and density study of the 1,4,7,10,13 pentaoxcyclopentadecane (15C5) as binary system and 15C5 in present of KBr (the ternary system) in aqueous solutions at 25oC. The results of the viscosity and density depend on type of system, and concentration rang. The relative viscosity obtain was fitted well by the use of Jones-Dole and Falkenhagen equations to the viscosity parameters i.e. the apparent molar volume and the effective rigid molar volume at infinite dilution. The results indicate that 4.2 mole of water are engaged in one mole of 15C5 and the complexation volume 0.015 dm3mol-1 K+ with 15C5 has been determine. The results are interpreted in terms of molecular and occupation of crown ether cavity by solvent molecules.

A field experiment was conducted at College farm, Water Technology Centre, Professor Jayashankar Telangana State Agriculture University (PJTSAU), Rajendranagar, Hyderabad during 2018 to 2019 to study the effect of differential drip irrigation and fertigation schedules on yield and economics of summer sesame. The experiment was framed with ten treatments viz., two irrigation levels (0.8 and 1.0 Epan), two fertigation levels (75% and 100% recommended dose of Nitrogen and Potassium), two schedules (Equal and differential) and two treatments with soil application of 100% RDF with Drip irrigation (1.0 Epan) and conventional furrow irrigation (1.0 IW/CPE) and were replicated thrice in Randomized Block Design. The results revealed that, application of 100% recommended dose of Nitrogen and Potassium (RDNK) through drip fertigation @ 0.8 or 1.0 Epan either in differential dosages based on crop growth stage or in equal splits recorded significantly superior yields (1011, 971, 977 and 990 kg/ ha, respectively) compared to the other treatments. These treatments recorded 13.5 and 26.7% higher yields, obtained from soil application of recommended dose of fertilizer (RDF) with drip irrigation at 1.0 Epan (882 kg/ha) and furrow irrigation at a 1.0 IW/CPE ratio (774 kg/ha). Further, the highest water productivity of 0.24 kg/m3 was recorded with differential application of 100% RDNK under a drip irrigation regime of 0.8 Epan. This treatment also recorded the highest gross returns ( ₹ 96,489 /ha), net returns (₹ 53,604 /ha) and B:C ratio (2.95).
Face masks impede basic and complex emotion recognition: Variation across the broader autism phenotype
Authors: Laycock Robin , Chouinard Philippe A. 
Published: July 2023

AbstractThe broader autism phenotype is characterised by atypical face perception. There is little understanding of how face masks―now commonly worn to protect against transmission of COVID‐19―might impact face processing across the broader autism phenotype. Neurotypical participants had their autistic traits measured and viewed masked and unmasked faces displaying basic and also complex expressions. Face masks reduced emotion recognition for basic and complex expressions in all participants. Autistic traits were linked to lower face emotion recognition, though this was primarily due to reduced accuracy with basic (masked and unmasked) expressions. Autistic traits were not linked to greater challenges in interpreting the emotions of masked faces.

Published: July 2023

ObjectiveRural residence has been associated with health disparities in rheumatic diseases and other chronic conditions in the United States. This study aimed to determine if a relationship exists between geographic residence and health care utilization outcomes for people with rheumatoid arthritis (RA) and osteoarthritis (OA) in a US‐wide rheumatic disease registry.MethodsParticipants were in FORWARD, The National Databank for Rheumatic Diseases, a US‐wide rheumatic disease longitudinal cohort completing questionnaires between 1999 and 2019. Health care utilization variables (ie, medical visits and diagnostic tests) from six‐month questionnaires were analyzed by geographic categories (small rural/isolated, large rural, and urban). Double selection LASSO with Poisson regression was used to assess the best model when examining the association between health care utilization variables and geographic residence.ResultsAmong 37,802 participants with RA, urban residents were more likely than small rural residents to use in‐person health care by most measures including physician visits and diagnostic tests. Urban residents reported more rheumatologist visits (incidence rate ratio [IRR], 1.22; 95% confidence interval [95% CI], 1.18–1.27) but fewer primary care visits (IRR 0.90; 95% CI 0.85–0.94). Among 8,248 participants with OA, urban residents were also more likely than rural residents to report health care utilization by most measures.ConclusionIndividuals residing in urban areas were more likely than those in rural areas to report in‐person health care utilization. Specifically, urban residents with RA were more likely to report rheumatologist visits, but less likely to report primary care visits. Less disparity existed in OA health care utilization, although an urban–rural disparity still existed by most measures.

AbstractVanadium‐based intercalation materials have attracted considerable attention for aqueous zinc‐ion batteries (ZIBs). However, the sluggish interlaminar diffusion of zinc ions due to the strong electrostatic interaction, severely restricts their practical application. Herein, oxygen vacancy‐enriched V2O5 structures (Zn0.125V2O5·0.95H2O nanoflowers, Ov‐ZVO) with expanded interlamellar space and excellent structural stability are prepared for superior ZIBs. In situ electron paramagnetic resonance (EPR) and X‐ray diffraction (XRD) characterization revealed that numerous oxygen vacancies are generated at a relatively low reaction temperature because of partially escaped lattice water. In situ spectroscopy and density functional theory (DFT) calculations unraveled that the existence of oxygen vacancies lowered Zn2+ diffusion barriers in Ov‐ZVO and weakened the interaction between Zn and O atoms, thus contributing to excellent electrochemical performance. The Zn||Ov‐ZVO battery displayed a remarkable capacity of 402 mAh g−1 at 0.1 A g−1 and impressive energy output of 193 Wh kg−1 at 2673 W kg−1. As a proof of concept, the Zn||Ov‐ZVO pouch cell can reach a high capacity of 350 mAh g−1 at 0.5 A g−1, demonstrating its enormous potential for practical application. This study provides fundamental insights into formation of oxygen‐vacant nanostructures and generated oxygen vacancies improving electrochemical performance, directing new pathways toward defect‐functionalized advanced materials.

AbstractFerroptosis as programmed cell death received considerable attention in cancer research. Recently, studies have associated ferroptosis with photodynamic therapy (PDT) because PDT promotes glutathione (GSH) deletion, glutathione peroxidase 4 (GPX4) degradation, and lipid peroxide accumulation. However, PDT‐induced ferroptosis may be potentially prevented by ferroptosis suppressor protein 1 (FSP1). To address this limitation, herein, a novel strategy is developed to trigger ferroptosis by PDT and FSP1 inhibition. For enhancement of this strategy, a photoresponsive nanocomplex, self‐assembled by BODIPY‐modified poly(amidoamine) (BMP), is utilized to stably encapsulate the inhibitor of FSP1 (iFSP1) and chlorin e6 (Ce6). The nanosystem promotes intracellular delivery, penetration, and accumulation of ferroptosis inducers in tumors with light irradiation. The nanosystem presents high‐performance triggering of ferroptosis and immunogenic cell death (ICD) in vitro and in vivo. Importantly, the nanoparticles increase tumor infiltration of CD8+ T cells and further enhance the efficacy of anti‐PD‐L1 immunotherapy. The study suggests the potential of photo‐enhanced synergistic induction of ferroptosis by the photoresponsive nanocomplexes in cancer immunotherapy.

Published: July 2023

AbstractSensing technologies based on plasmonic nanomaterials are of interest for various chemical, biological, environmental, and medical applications. In this work, an incorporation strategy of colloidal plasmonic nanoparticles (pNPs) in microporous polymer for realizing distinct sorption‐induced plasmonic sensing is reported. This approach is demonstrated by introducing tin‐doped indium oxide pNPs into a polymer of intrinsic microporosity (PIM‐1). The composite film (pNPs‐polymer) provides distinct and tunable optical features on the fiber optic (FO) platform that can be used as a signal transducer for gas sensing (e.g., CO2) under atmospheric conditions. The resulting pNPs‐polymer composite demonstrates high sensitivity response on FO in the evanescent field configuration, provided by the dramatic response of modes above the total‐internal‐reflection angle. Furthermore, by varying the pNPs content in the polymer matrix, the optical behavior of the pNPs‐polymer composite film can be tuned to affect the operational wavelength by over several hundred nanometers and the sensitivity of the sensor in the near‐infrared range. It is also shown that the pNPs‐polymer composite film exhibits remarkable stability over a period of more than 10 months by mitigating the physical aging issue of the polymer.

AbstractLiving cells efflux intracellular ions for maintaining cellular life, so intravital measurements of specific ion signals are of significant importance for studying cellular functions and pharmacokinetics. In this work, de novo synthesis of artificial K+‐selective membrane and its integration with polyelectrolyte hydrogel‐based open‐junction ionic diode (OJID) is demonstrated, achieving a real‐time K+‐selective ion‐to‐ion current amplification in complex bioenvironments. By mimicking biological K+ channels and nerve impulse transmitters, in‐line K+‐binding G‐quartets are introduced across freestanding lipid bilayers by G‐specific hexylation of monolithic G‐quadruplex, and the pre‐filtered K+ flow is directly converted to amplified ionic currents by the OJID with a fast response time at 100 ms intervals. By the synergistic combination of charge repulsion, sieving, and ion recognition, the synthetic membrane allows K+ transport exclusively without water leakage; it is 250× and 17× more permeable toward K+ than monovalent anion, Cl−, and polyatomic cation, N‐methyl‐d‐glucamine+, respectively. The molecular recognition‐mediated ion channeling provides a 500% larger signal for K+ as compared to Li+ (0.6× smaller than K+) despite the same valence. Using the miniaturized device, non‐invasive, direct, and real‐time K+ efflux monitoring from living cell spheroids is achieved with minimal crosstalk, specifically in identifying osmotic shock‐induced necrosis and drug‐antidote dynamics.
