Authors: Carmela B. Bonifacio Anna , M. Mistades Voltaire
Published: April 2024

The major intention of this study is to design and validate manipulatives for homebased physics experiments. The Covid-19 pandemic has caused tremendous and rapid amendments to educational systems worldwide, immediately shifting from traditional on-the-ground teaching to virtual classroom instruction or modular learning approach to name a few. Similarly, it has made laboratory experiments problematic. Demonstrations are limited just to the four corners of the electronic gadget’s screen, while simulations can only do so much in terms of experiential learning; hence, the urgency of developing these low-cost laboratory kits for students’ use at home. The laboratory activities and kits went through thorough examination for validation by 3 experts in the field of Physics, all of them holding Masters-degree. The setup was found to be valid (overall mean of 4.67 from a 5-point Likert scale validation tool). The effectiveness, in terms of the performance of learners, was established using quasi-experimental methods involving 30 students (15 males and 15 females) in the control group and 30 learners (15 males and 15 females) in the experimental group. The control group was exposed to customary lectures via online classes with virtual simulations. The students in the experimental group attended the same online lectures and were provided with the home-based manipulative kit. The analysis and interpretation of data collected from the pretest-posttest scores of the student participants revealed that the laboratory manipulative kits are effective and highly acceptable. The normalized gain of the experimental group (g = 0.82, high gain) was significantly higher than that of the control group (g = 0.45, medium gain).

Published: April 2024

Peningkatan kadar air dalam proses penyimpanan biodiesel merupakan permasalahan yang harus dicari solusinya. Salah satu solusi yang ditawarkan yaitu melalui penggunaan sistem dewatering biodiesel dengan teknologi vakum termal yang dapat menurunkan kadar air pada biodiesel sehingga sesuai spesifikasi yang ditetapkan. Pada penelitian ini, sistem dewatering biodiesel dengan teknologi vakum termal memiliki komponen utama yaitu tangki evaporator biodiesel. Walaupun penurunan kadar air masih sesuai standar, namun optimasi perlu terus dilakukan agar kadar air pada biodiesel <200 ppm.  Penelitian ini bertujuan memperoleh aliran turbulen yang optimal dari tangki evaporator biodiesel yang dilengkapi sparger pipa dengan variasi lubang yang berbeda melalui simulasi CFD. Selain itu, simulasi ini diharapkan dapat memberikan pemahaman mengenai perilaku aliran biodiesel ketika melewati orifice plate dan sparger pipa sehingga diperoleh kondisi operasi yang terbaik. Penelitian meliputi simulasi CFD tangki evaporator biodiesel menggunakan orifice plate dan sparger pipa. Empat model yang diteliti yaitu tangki evaporator biodiesel yang dilengkapi orifice plate, sparger pipa A, sparger pipa B dan sparger pipa C. Berdasarkan hasil simulasi, tangki evaporator biodiesel yang dilengkapi sparger pipa C merupakan yang paling optimal dalam menghasilkan aliran turbulen. Hal tersebut berdasarkan sebaran kecepatan yang ditampilkan pada Re=5000, Re=10000, dan Re=50000. Dengan demikian, tangki evaporator biodiesel dengan pemasangan sparger pipa C berpotensi menurunkan kadar air lebih tinggi dibandingkan dengan pemasangan orifice plate, sparger pipa A dan sparger pipa B.

Published: April 2024

Dans le contexte de rareté des ressources forestières, évaluer le degré d’exploitation des produits forestiers non ligneux est crucial pour comprendre les pressions exercées sur les produits forestiers non ligneux et in fine de mettre en place des stratégies visant une exploitation rationnelle et durable des produits forestiers non ligneux. Cette étude a pour objectifs d’analyser la dynamique d’exploitation des produits forestiers non ligneux. Un suivi de l’exploitation des produits forestiers non ligneux a été réalisé chez 260 exploitants répartis en 30 groupements. Un questionnaire et un guide d’entretien ont été utilisés pour la collecte des données complémentaires et ont été administrés auprès de 150 producteurs au niveau de quatre communes Les résultats montrent qu’entre 2012 et 2018, le volume d’exploitation du pain de singe est passé de 20,087 tonnes à 88,457 tonnes, de 1,19 T à 45,231 tonnes pour le Saba. Celui du miel est passé de 4 354 litres en 2012 à 6 694 litres, de10 280 litres à 35 563 litres pour l’huile de palme. Quant au Néré, son exploitation est passée de 79, 996 tonnes en 2012 à 263, 141 tonnes. La commercialisation des produits exploités a permis de générer plus de 208 859 000 millions de FCFA par an. Il ressort des enquêtes de perception que l’ensemble des produits forestiers subissent une forte pression et que leur disponibilité est de plus en plus faible. Dès lors, des stratégies résilientes sont à adopter allant de l’exploitation contrôlée à la conservation de ces ressources. In the context of scarce forest resources, assessing the degree of exploitation of non-timber forest products is crucial to understanding the pressures exerted on non-timber forest products and, ultimately, to implementing strategies aimed at rational and sustainable exploitation of non-timber forest products. The aim of this study is to analyze the dynamics of non-timber forest product exploitation. Non-timber forest product harvesting was monitored among 260 farmers in 30 groups. A questionnaire and interview guide were used to collect additional data, and were administered to 150 producers in four communes. The results show that between 2012 and 2018, the volume of monkey bread harvested rose from 20.087 tonnes to 88.457 tonnes, and from 1.19 T to 45.231 tonnes for Saba. Honey production rose from 4,354 liters in 2012 to 6,694 liters, and palm oil from 10,280 liters to 35,563 liters. Néré production rose from 79.996 tonnes in 2012 to 263.141 tonnes. The marketing of harvested products generated more than 208,859,000 million FCFA per year. Perception surveys show that all forest products are under heavy pressure, and that their availability is becoming increasingly limited. Resilient strategies must therefore be adopted, ranging from controlled harvesting to conservation of these resources.

Authors: Fegada Alfateh , Veres Zoltan
Published: April 2024

Entrepreneurial marketing “EM” is considered to be suitable for small businesses. However, innovation orientation “IO” as an EM dimension is a critical instrument that small and medium-sized businesses can use to obtain a competitive advantage. Thus, the general objective of this study is to explore and describe the significant relationship between IO and firm performance “FP” in SMEs in Khartoum-Sudan utilizing technological capabilities “TCPs” as a moderating variable. The resource-based view “RBV” provides the theoretical foundation for this study regarding the effect of innovation orientation on firm performance through technological capabilities. To achieve this objective, we assumed the following hypothesis: H1: Innovation orientation has a significant relationship with firm performance {profitability, sustainability, and customer satisfaction}. H2: We assume that TCPs can positively moderate the relationship between IO and FP. In this manner, our study is quantitative. Reliable with the purpose of this study. Furthermore, our study relied on the “Positivism philosophy”, a deductive approach to theory development. Accordingly, overall, 255 responses were received in responding to our online questionnaire. To analyze the data firstly PCA, Correlation, and Rotation matrix were utilized to test the appropriateness of the study pre-model and check the validity of the questionnaire measurements. secondly, we used Path analysis to examine the significant relationships between study variables. Consequently, the findings confirm both significant and insignificant relationships between IO and FP. Our analysis revealed significant relationships between innovation orientation, technological capabilities, and firm performance indicators such as profitability, sustainability, and customer satisfaction. Moreover, we found that technological capabilities play a crucial moderating role in enhancing the effects of innovation orientation strategy on firm performance. Anyhow, these results confirmed the partial support of the study’s hypotheses.

Two Dark Clouds on the Space-Time Horizon
Authors: SINGH TEJINDER P.
Published: April 2024

(i) Investigations of stellar systems known as wide binaries suggest that Newton’s law of gravitation breaks down at low accelerations. This can be explained by proposing a fifth force with $U(1)$ gauge symmetry, whose corresponding gauge boson is the sought for dark matter candidate. (ii) Relativistic causality (i.e. no faster than light signalling) permits nonlocal correlations stronger than those permitted by quantum mechanics. This can be explained if our universe possesses a second 4D spacetime with a signature opposite to ours. (iii) Such a fifth force, and a second spacetime, arise naturally in a recently proposed theory of unification based on an $E_8\times E_8$ symmetry. Our spacetime arises from breaking of an $SU(2)_R\times U(1)_{YDEM}$ symmetry, and the second spacetime arises from broken electroweak symmetry.

Authors: Rempel Anne M. L. , Persons Jane E. , Bengtson Kate , Nashelsky Marcus B.
Published: April 2024

Objectives. To examine sudden and unexpected or trauma-related deaths that occurred in the presence of law enforcement in Johnson County, Iowa, between 2011 and 2020.

Methods. We identified deaths in the presence of law enforcement using definitions from the National Association of Medical Examiners. We obtained data, including demographics, cause and manner of death, toxicology results, and circumstances and location of event leading to death, from comprehensive medical examiner investigative reports.

Results. There were 165 deaths that occurred in the presence of law enforcement: 114 were from a known disease, and 51 were either trauma related or the sudden, unexpected initial presentation of a previously unrecognized disease. Three deaths occurred in the context of physical restraint by law enforcement. Suicide was the leading manner of death among trauma-related deaths; the means of suicide was predictable based on in-custody (hanging) or precustody (firearm) circumstances.

Conclusions. Our findings highlight the potential role of medical examiners and coroners in improving completeness of data on reporting death in the presence of law enforcement to public health agencies. ( Am J Public Health. 2024;114(6):642–650. https://doi.org/10.2105/AJPH.2024.307616 )
Cut and capture system technology for demilitarization of underwater munitions
Authors: Schmit Steve
Published: April 2024

Munitions are encountered in a variety of underwater environments as unexploded ordnance (UXO) or munitions and explosives of concern (MEC). These items can cause unacceptable explosive risks to critical infrastructure, recreational divers, and fishermen. The primary goal of the demonstrations was to validate an underwater suite of tools that can be used to render underwater UXO and MEC safe in shallow water (i.e., up to 100 ft). US Navy underwater ranges in the Gulf of Mexico, south of the Naval Support Activity–Panama City, were selected for the first two demonstrations to fully display the integrated system by processing inert munitions, such as the Navy 5 in./38 cal and the Army 105 mm High Explosive (HE) M1 projectile. The third demonstration, however, occurred at the Naval Surface Warfare Center (NSWC), Crane, Lake Glendora Test Facility, in Sullivan, Indiana. Twenty US Army 105 mm HE M1 projectiles filled with TNT were successfully processed. Overall, this project showed that Gradient Technology’s high-pressure waterjet demilitarization technology can be reliably operated underwater at depths less than 100 ft of seawater when the supporting equipment is located on the deck of a vessel or floating pier system.
Creating authentic assessment in mathematics
Authors: Symonds Ria , Mott Lisa
Published: April 2024

Assessment of students’ mathematics knowledge within higher education (HE) has normally taken a very traditional approach. Closed-book assessments have long been the favoured mode of assessment (Iannone Simpson, 2011) which often requires students to recall facts, formulae, and methods. One could argue that this type of assessment is limited in its ability to effectively assess how well a student’s ability to authentically use mathematics has developed. Due to the recent pandemic, many institutions were forced to rethink their assessment methods so that they could be delivered online and remotely. As such, there has been a renewed sense of need for more ‘authentic’ assessments for mathematics-based programmes.In this paper, we will discuss our journey of creating more authentic assessments for apprentices enrolled on a new Data Science Degree Apprenticeship, particularly in mathematics/statistics. We will compare two years of delivery of the course; the first year of delivery which comprised of traditional assessment methods (coursework/exam) and the second year of delivery that used more authentic assessment methods. We will discuss the pros and cons of each model by reflecting on our practice and drawing on apprentices’ feedback.
Various Aspects of Approximative τ -Compactness in Banach Spaces
Authors: Das Syamantak , Paul Tanmoy
Published: April 2024

We study approximative τ -compactness in Banach spaces, where τ is the norm or weak topology. The family of Banach spaces with Fr´echet differentiable norms falls under the category of spaces where every w ∗ -closed finite codimensional subspace is approximatively compact in the duals, is observed. On the other hand, we derive that if every w ∗ -closed hyperplane in X ∗ is strongly proximinal, then X is Asplund. We conclude that a smooth Banach space is Fr´echet smooth if and only if every w ∗ -closed hyperplane is approximatively compact in its dual. The property approximative τ -compactness is characterized in a variety of ways for finite codimensional subspaces. It is established that a separable Banach space X is Asplund if and only if X ∗ admits a dual CLUR renorming. This property is discussed in the context of quotient spaces. Stability results for approximative τ -compactness in the spaces of Bochner integrable functions and polyhedral sum of Banach spaces are also presented.

The purpose of the study was to investigate the paybacks of linking senior high school geometry to Akan cultural practice. The study area was the Ashanti region, which houses a chunk of the Akan people. The targeted population for the study included experienced mathematics teachers and people who are well-versed in Akan traditional art. Ten participants were recruited, including seven experienced mathematics teachers and three craftsmen, using purposive and snowball sampling methods. Data collection was conducted through interviews to elicit in-depth information from participants using a semi-structured interview guide. The data was analysed using thematic analysis. According to the analysis, teaching geometry with an Akan cultural perspective fosters conceptual understanding and raises academic achievement through lifelong learning. Secondary, it produces students who are patriotic and innovative, ready to face real-life challenges instead of becoming a burden on society. The researchers concluded that the Akan culture is embedded with concepts that are geometric, and it serves as good tool for teaching and learning geometry at the Senior High School

In the absence of any visible solid surface, the rotation period of the giant planets has been inferred from periodic phenomena tied to the magnetic field produced in their deep interior. The main method relied on remote radio auroral observations, sometimes complemented by in situ magnetic measurements. For Uranus, such measurements acquired during the Voyager 2 flyby in 1986 yielded a rotation period of 17.24±0.01h1. This fundamental planetary parameter, referenced since then by the International Astronomical Union, is the basis of the Uranian longitude model2. Still, the period uncertainty limits its validity to a few years, after which the orientation of the magnetic axis was lost. Here, we use a novel approach, based on the long term (2011-2022) tracking of Uranus’ magnetic poles from Hubble Space Telescope images of its ultraviolet aurorae, to achieve a new rotation period of 17.247864±0.000010h. It is consistent with, although 28s longer than, the Voyager 2 period. This much more precise determination leads to a new longitude model now valid over decades, from before the Voyager 2 epoch up to the arrival of any future Uranus mission. It also has strong direct implications on formation scenarios, interior models, dynamo theories and studies of the magnetosphere. This novel approach stands as an alternate method to determine the rotation rate of any object hosting a magnetosphere and rotationally modulated aurorae, in our solar system and beyond.

Authors: Pabon-Rodriguez Felix M.
Published: April 2024

Addressing health disparities has become an important concern in public health, underlying the need to comprehensively investigate and understand the social determinants of health to foster equitable healthcare outcomes. This descriptive analysis examines the temporal and spatial patterns of social determinants of health in United States nursing homes from 2020 to 2023. Leveraging quarterly data obtained from the Centers for Medicare and Medicaid Services, the study provides an overview of key social drivers of health, including functional status, cognitive status, psychosocial factors, geriatric syndromes, and more. Through visual exploration, the study aims to elucidate trends and variations over time and across different regions. The analysis adopts a descriptive approach, emphasizing qualitative insights and policy considerations. This study contributes to a better understanding of the contextual factors influencing health outcomes in nursing homes, offering valuable insights for potential policy enhancements.
Deficient GATA6-ACKR3/CXCR7 signaling leads to bicuspid aortic valve
Authors: Pompa José Luis de la , Piñeiro-Sabarís Rebeca , MacGrogan Donal
Published: April 2024

The cardiac outflow tract (OFT) transiently links the ventricles to the aortic sac and gives rise to the arterial valves. Abnormalities of the arterial valves, mainly bicuspid aortic valve (BAV), are the commonest congenital anomalies.Gata6inactivating mutations cause cardiac OFT defects and BAV, but the cellular and molecular mechanisms are poorly understood. We find thatGata6STOP/+mice, generated by CRISPR-Cas9, display highly penetrant BAV (70%), and a membranous ventricular septal defect (43%). OFT development inGata6STOP/+mice is characterized by decreased proliferation and increased presence of ISL1-positive progenitor cells, suggestive of aberrant cardiovascular differentiation. In support, conditionalGata6deletion with theMef2cAHF − Credriver line recapitulatesGata6STOP/+phenotypes, indicating a cell-autonomous requirement forGata6in the SHF.Gata6STOP/+mice display dramatic reductions in OFT length and caliber, associated with deficient cardiac neural crest cells (cNCCs) contribution in the mutant OFT, potentially underlying the valvulo-septal defects. RNA-seq analysis ofGata6STOP/+OFT reveal multiple depleted pathways linked to cell proliferation and migration, and highlightACKR3/CXCR7as a candidate gene regulating migratory effects downstream of GATA6. Consistently, mesenchymal cell migration and invasion are drastically reduced in explantedGata6STOP/+OFT tissue. Supplementing wild type OFT explants with CXCR7 agonists decreases mesenchymal cell migration and increases invasion, these effects are suppressed in theGata6STOP/+explants, suggesting that CXCR7-mediated migration and invasion is Gata6-dependent. These findings demonstrate a requirement for CXCR7 downstream ofGata6in OFT development and suggest that the cellular defects associated with BAV in GATA6-deficient mice can be ascribed, in part, to reduced CXCR7 function.
Anterior Tenting vs. Wrapping Technique for Acellular Dermal Matrix in Breast Reconstruction under Post-mastectomy Radiotherapy in Rats
Authors: Kim Ji-Young , Jin Ung Sik
Published: April 2024

This study compares outcomes between anterior tenting and whole wrapping techniques in prepectoral breast reconstruction using ADM. Fifteen rats were divided into control, anterior tenting, and whole wrapping groups, each receiving two silicone implants. Only silicone implants were placed in the control group. The anterior surface of the implants was covered with ADM in the anterior tenting group, whereas the implants were fully wrapped with ADM in the whole wrapping group. Animals were irradiated on one side of the back three weeks postoperatively and sacrificed three months postoperatively. The range of change in tonometry values with or without irradiation in whole wrapping tended to be larger than that of anterior tenting (p < 0.05). The cellular capsule was significantly thinner on the side covered by ADM (p < 0.05). There were no significant differences observed in the other microscopic features of the cellular capsule. The microscopic analysis of ADM revealed significant increases in total capsule thickness and collagen density with radiation exposure, while a significant decrease was observed in ⍺-SMA positive area, CD3 positive cell counts and F4/80 positive area (p < 0.05). In patients with the possibility of adjuvant radiation therapy, the anterior tenting technique is recommended over whole wrapping.
Oxygen evolution reaction on IrO2(110) is governed by Walden-type mechanisms

Published: April 2024

Oxygen evolution reaction (OER) is a key process for sustainable energy, although renewable sources require the use of proton exchange membrane electrolyzers, with IrO2-based materials being the gold standard due to their high activity and stability under dynamic anodic polarization conditions. However, even for the (110) facet of a single-crystalline IrO2 model electrode, the reaction mechanism is not settled yet due to contradictory reports in literature. In the present manuscript, we disentangle the conflicting results of previous theoretical studies in the density functional theory approximation. We demonstrate that dissimilar reaction mechanisms and limiting steps for the OER over IrO2(110) are obtained for different active surface configurations present on the IrO2 electrode. In contrast to previous studies, we factor Walden-type mechanisms, in which the formation of the product O2 and adsorption of the reactant H2O occur simultaneously, into the analysis of the elementary steps. Combining free-energy diagrams along the reaction coordinate and Bader charge analysis of the active site under constant potential, we elucidate why mononuclear- or bifunctional-Walden pathways excel the traditional OER mechanisms for the OER over IrO2(110). Our computational methodology to identify the reaction mechanism and limiting step of proton-coupled electron transfer steps is universally applicable to electrochemical processes in the field of energy conversion and storage.
Self-organizing neuromorphic nanowire networks are stochastic dynamical systems

Published: April 2024

Neuromorphic computing aims to develop software and hardware platforms emulating the information processing effectiveness of our brain. In this context, self-organizing neuromorphic nanonetworks have been demonstrated as suitable physical substrates for in materia implementation of unconventional computing paradigms, like reservoir computing. However, understanding the relationship between emergent dynamics and information processing capabilities still represents a challenge. Here, we demonstrate that nanowire-based neuromorphic networks are stochastic dynamical systems where the signals flow relies on the intertwined action of deterministic and random factors. We show through an experimental and modeling approach that these systems combine stimuli-dependent deterministic trajectories and random effects caused by noise and jumps that can be holistically described by an Ornstein-Uhlenbeck process, providing a unifying framework surpassing current modeling approaches of self-organizing neuromorphic nanonetworks (not only nanowire-based) that are limited to either deterministic or stochastic effects. Since information processing capabilities can be dynamically tuned by controlling the network’s attractor memory state, these results open new perspectives for the rational development of physical computing paradigms exploiting deterministic and stochastic dynamics in a single hardware platform similarly to our brain.
