Authors: Raghani Priyanka
Published: November 2022

Tourism and the hospitality industry make up a vital part of the economy, particularly in the developing countries, yet it is particularly susceptible to natural disasters and man-made catastrophes. The Travel is one of the world's biggest ventures and the economies of numerous countries are driven, generally, by their vacationer exchange. In the situation of pandemic Covid-19, India is no exception; the tourism industry has seen a tremendous decline during 2020. GOI has a pressing position to do in recuperation and improvement of the tourism industry. To stay away from the spread of the Coronavirus legislature of India forced a lockdown in the country. National and International travel limitations, made horrendously terrible impact on Indian travel industry by causing enormous harm towards nation's GDP and furthermore many individuals lost their jobs. The present study attempts to deduce the impact of Corona Virus on Indian Travel and Hospitality Industry and furthermore centres around re-establishing the Indian travel industry by proposing/prescribing the industry to change their method towards sightseers which brings back the withdrew magnificence.

To determine the degree of the liver failure in cirrhotic patients we use serum liver function tests In contrast with tests, serum cholinesterase values are low in liver failure. Purpose of the study is to establish if serum cholinesterase corelates with the level of liver disfunction. According to the Child-Pugh Score, 70 patients with chronic liver disease were selected and grouped into 3 categories. Serum cholinesterase, serum albumin and International Normalized Ratio were analyzed and correlations between them were calculated. We observed that the cholinesterase levels tend to decrease according to the Child-Pugh score, lowest in the C group and highest in the A group. The cholinesterase correlated with the albumin serum levels, value of MELD-Na score and Child-Pugh score and did not corelate to INR. In conclusion, serum cholinesterase can be used as an indicator of the liver disfunction grade.
Unfolding Smart Specialisation for Regional Economic Resilience: the role of Industrial Structure
Authors: Lazzeretti Luciana , Oliva Stefania , Innocenti Niccolò
Published: November 2022

The European Regional Development Funds for the programmatic cycle 2014-2020 aims to support regions that implement an innovation strategy based on Smart Specialisation. Within this framework, the European Commission emphasises the role of smart specialisation in favouring regional transformation, enhancing competitiveness and fostering resilience. However, the concepts of smart specialisation and resilience have been poorly combined. The article aims at investigating their relationship to understand if a smart specialisation strategy may promote the economic resilience of regions in response to major economic shocks. Drawing upon the concepts of adaptation/adaptability, the analysis investigates the relatedness of new industrial specialisations to the existing industrial structure before and after a shock occurrence. Evaluating the resilience of Italian provinces in relation to the economic crisis of 2008, the analysis aims to understand if provinces that resisted and recovered better followed a smart specialisation framework where new industrial specialisations are related to the existing industrial structure.

Authors: Wolf Jan , Marto Marco , Madaleno Mara , Marques João Lourenço
Published: November 2022

The adjustment of services of general interest to ageing and shrinking populations is a significant challenge in many European regions. This article analyses the response in the number of primary schools to changes in the student population in the municipalities of mainland Portugal between 2007 and 2016. It focuses on the time lag of this adjustment, the territorial factors that influence it and the role of spatial spill-over effects. The main finding is that the relationship between the number of schools and the number of students is not straightforward and can only be understood considering the broader geographic contexts and spatial dependence structures.
Tertiary industries’ value-added as a linkage’s engine: An interstate input-output application for Brazilian regions
Authors: Sanguinet Eduardo Rodrigues , Rodriguez-Puello Gabriel
Published: November 2022

Tertiary industries’ value-added have been considered an essential input for any production chain, as they have the potential to connect regions and services activities across networks. Moreover, spatially, services move more straightforward than the manufacturing of resource-based industries. This study estimates the interregional and inter-industry linkages regarding a set of services-related economic sectors and accounts for the trade in value-added (TiVA) measures, considering intraregional and interregional trade based on an interstate input-output application for Brazil. The main findings reveal that the poorest Brazilian states tend to lose linkages opportunities in services activities, remaining hostages to supply natural resources to production networks for subnational and foreign demand. On the other hand, the potential for gains from connections in the services’ networks reveals greater spatial dispersion across regional hierarchies, increasing the concentration in large urban agglomerations. In this regard, the paper concludes that the connectivity potential of services at the intraregional level can be an essential starting point to promote innovative systems away from large urban areas in the wealthiest regions inside Brazil, potentially reducing value-added imbalances in internal geography trade flows.

This paper reports on the γ-ray properties of the 2018 Galactic nova V392 Per, spanning photon energies ∼0.1 GeV–100 TeV by combining observations from the Fermi Gamma-ray Space Telescope and the HAWC Observatory. As one of the most rapidly evolving γ-ray signals yet observed for a nova, GeV γ-rays with a power-law spectrum with an index Γ = 2.0 ± 0.1 were detected over 8 days following V392 Per’s optical maximum. HAWC observations constrain the TeV γ-ray signal during this time and also before and after. We observe no statistically significant evidence of TeV γ-ray emission from V392 Per, but present flux limits. Tests disfavor the extension of the Fermi Large Area Telescope spectrum to energies above 5 TeV by 2 standard deviations (95%) or more. We fit V392 Per’s GeV γ-rays with hadronic acceleration models, incorporating optical observations, and compare the calculations with HAWC limits.
Spectral Evolution of Ultraluminous X-Ray Pulsar NGC 300 ULX-1

Published: November 2022

We report on results from a 1 yr soft X-ray observing campaign of the ultraluminous X-ray pulsar NGC 300 ULX-1 by the Neutron star Interior Composition Explorer (NICER) during 2018–2019. Our analysis also made use of data from Swift/XRT and XMM-Newton in order to model and remove contamination from the nearby eclipsing X-ray binary NGC 300 X-1. We constructed and fitted a series of 5 day averaged NICER spectra of NGC 300 ULX-1 in the 0.4–4.0 keV range to evaluate the long-term spectral evolution of the source, and we found that an absorbed power-law model provided the best fit overall. Over the course of our observations, the source flux (0.4–4.0 keV; absorbed) dimmed from 2 × 10−12 to below 10−13 erg s−1 cm−2 and the spectrum softened, with the photon index going from Γ ≈ 1.6 to Γ ≈ 2.6. We interpret the spectral softening as reprocessed emission from the accretion disk edge coming into view while the pulsar was obscured by the possibly precessing disk. Some spectral fits were significantly improved by the inclusion of a disk blackbody component, and we surmise that this could be due to the pulsar emerging in between obscuration episodes by partial covering absorbers. We posit that we observed a low-flux state of the system (due to line-of-sight absorption) punctuated by the occasional appearance of the pulsar, indicating short-term source variability nested in longer-term accretion disk precession timescales.
Multiple Regions of Nonthermal Quasiperiodic Pulsations during the Impulsive Phase of a Solar Flare

Published: November 2022

Flare-associated quasiperiodic pulsations (QPPs) in radio and X-ray wavelengths, particularly those related to nonthermal electrons, contain important information about the energy release and transport processes during flares. However, the paucity of spatially resolved observations of such QPPs with a fast time cadence has been an obstacle for us to further understand their physical nature. Here, we report observations of such a QPP event that occurred during the impulsive phase of a C1.8-class eruptive solar flare using radio imaging spectroscopy data from the Karl G. Jansky Very Large Array (VLA) and complementary X-ray imaging and spectroscopy data. The radio QPPs, observed by the VLA in the 1–2 GHz with a subsecond cadence, are shown as three spatially distinct sources with different physical characteristics. Two radio sources are located near the conjugate footpoints of the erupting magnetic flux rope with opposite senses of polarization. One of the sources displays a QPP behavior with a ∼5 s period. The third radio source, located at the top of the postflare arcade, coincides with the location of an X-ray source and shares a similar period of ∼25–45 s. We show that the two oppositely polarized radio sources are likely due to coherent electron cyclotron maser emission. On the other hand, the looptop QPP source, observed in both radio and X-rays, is consistent with incoherent gyrosynchrotron and bremsstrahlung emission, respectively. We conclude that the concurrent, but spatially distinct QPP sources must involve multiple mechanisms which operate in different magnetic loop systems and at different periods.
Stellar Obliquity from Spot Transit Mapping of Kepler-210
Authors: Valio Adriana , Araújo Alexandre
Published: November 2022

Stellar obliquity, the angle between the stellar spin and the perpendicular to the planetary orbit, also known as the spin–orbit angle, holds clues to the formation and evolution of planetary systems. When a planet transits a star periodically, it may cross in front of a stellar spot, producing a noticeable signal on the transit light curve. Spot transit mapping can be used to measure stellar obliquity. Here we present the analysis of Kepler-210, a K-dwarf star with two mini-Neptune-size planets in orbit. Interestingly, the spot mapping from the outer planet, Kepler-210 c, resulted in a spot distribution with no spots detected at longitudes >38°, whereas the spots occulted by Kepler-210 b displayed all range of longitudes. The best explanation for this was that Kepler-210 c exhibited an inclined orbit, while the orbit of Kepler-210 b was parallel to the stellar equator. Thus, transits of Kepler-210 c occulted different latitude bands of the star. The observed maximum spot topocentric longitude of 38° implied an orbital obliquity of 18°–45° for Kepler-210 c. Further considering a symmetric spot distribution in latitude with respect to the stellar equator, the obliquity was restricted to 34.°8, implying a maximum spot latitude of 40°. The differential rotation profile calculated from the oblique orbit for Kepler-210 c agreed with that obtained from the spots occulted by Kepler-210 b. Combining results from both planets yields a rotational shear of ΔΩ = 0.0353 ± 0.0002 rad day−1 and a relative rotational shear of 6.9%. The causes of the Kepler-210 c misalignment remain to be explained.
Statistical Analysis of the Radial Evolution of the Solar Winds between 0.1 and 1 au and Their Semiempirical Isopoly Fluid Modeling

Published: November 2022

Statistical classification of the Helios solar wind observations into several populations sorted by bulk speed has revealed an outward acceleration of the wind. The faster the wind, the smaller this acceleration in the 0.3–1 au radial range. In this paper, we show that recent measurements from the Parker Solar Probe (PSP) are compatible with an extension closer to the Sun of the latter Helios classification. For instance, the well-established bulk speed/proton temperature (u, T
p) correlation and bulk speed/electron temperature (u, T
e) anticorrelation, together with the acceleration of the slowest winds, are verified in PSP data. We also model the combined PSP and Helios data using empirical Parker-like models for which the solar wind undergoes an “isopoly” expansion: isothermal in the corona, then polytropic at distances larger than the sonic point radius. The polytropic indices are derived from the observed temperature and density gradients. Our modeling reveals that the electron thermal pressure has a major contribution in the acceleration process of slow and intermediate winds (in the range of 300–500 km s−1 at 1 au) over a broad range of distances and that the global (electron and proton) thermal energy alone is able to explain the acceleration profiles. Moreover, we show that the very slow solar wind requires, in addition to the observed pressure gradients, another source of acceleration.

computed with the ÆSOPUS code under the assumption of thermodynamic equilibrium. In comparison to the previous version, ÆSOPUS
1.0, we updated and expanded molecular absorption to include 80 species, mostly using the recommended line lists currently available from the ExoMol and HITRAN databases. Furthermore, in light of a recent study, we revised the H− photodetachment cross section, added the free–free absorption of other negative ions of atoms and molecules, and updated the collision-induced absorption due to H2/H2, H2/H, H2/He, and H/He pairs. Using the new input physics, we computed tables of Rosseland mean opacities for several scaled-solar chemical compositions, including Magg et al.'s most recent one, as well as α-enhanced mixtures. The differences in opacity between the new ÆSOPUS
2.0 and the original ÆSOPUS
1.0 versions, as well as other sets of calculations, are discussed. The new opacities are released to the community via a dedicated webpage that includes both precomputed tables for widely used chemical compositions and a web interface for calculating opacities on the fly for any abundance distribution.

We report the discovery of Specter, a disrupted ultrafaint dwarf galaxy revealed by the H3 Spectroscopic Survey. We detected this structure via a pair of comoving metal-poor stars at a distance of 12.5 kpc, and further characterized it with Gaia astrometry and follow-up spectroscopy. Specter is a 25° × 1° stream of stars that is entirely invisible until strict kinematic cuts are applied to remove the Galactic foreground. The spectroscopic members suggest a stellar age τ ≳ 12 Gyr and a mean metallicity

≈ −2.6, Specter is by far the least-luminous dwarf galaxy stream known. We estimate that dozens of similar streams are lurking below the detection threshold of current search techniques, and conclude that spectroscopic surveys offer a novel means to identify extremely low surface brightness structures.
Searching for Compact Objects in Binaries with Gaia DR3

Published: November 2022

We search for compact objects in binaries based on Gaia DR3. A sample of 10 targets is derived under the following conditions: the radial velocity variable, low temperature (T
eff < 6000 K), high mass function (f(M
2) > 1M
⊙), and ellipsoidal-like light curves. Two targets have LAMOST spectroscopic observations, one of which is a double-lined spectroscopic binary. The observational data of seven targets are not self-consistent, since their photometric periods are even shorter than the theoretical minimum orbital periods calculated by the stellar parameters from Gaia DR3. After excluding these seven inconsistent targets and another target contaminated by a near-bright star, the remaining two targets may contain compact objects worth follow-up observations. This work may serve as an example to demonstrate the feasibility of searching for compact objects in the massive Gaia data.
Variability from Thermoresistive Instability in the Atmospheres of Hot Jupiters
Authors: Hardy Raphaël , Cumming Andrew , Charbonneau Paul
Published: November 2022

The atmosphere of a hot Jupiter may be subject to a thermoresistive instability, in which the increasing electrical conductivity with temperature leads to runaway ohmic heating. We introduce a simplified model of the local dynamics in the equatorial region of a hot Jupiter that incorporates the back reaction on the atmospheric flow as the increasing electrical conductivity leads to flux freezing, which in turn quenches the flow and therefore the ohmic heating. We demonstrate a new time-dependent solution that emerges for a temperature-dependent electrical conductivity (whereas a temperature-independent conductivity always evolves to a steady state). The periodic cycle consists of bursts of Alfvén oscillations separated by quiescent intervals, with the magnetic Reynolds number alternating between values smaller than and larger than unity, maintaining the oscillation. We investigate the regions of pressure and temperature in which the instability operates. For the typical equatorial accelerations seen in atmospheric models, we find instability at pressures ∼0.1–1 bar and temperatures ≈1300–1800 K for magnetic fields ∼10 G. Unlike previous studies based on a constant wind velocity, we find that the instability is stronger for weaker magnetic fields. Our results add support to the idea that variability should be a feature of magnetized hot Jupiter atmospheres, particularly at intermediate temperatures. The temperature dependence of the electrical conductivity is an important ingredient that should be included in MHD models of hot Jupiter atmospheric dynamics.
Multiple Transitions in Vacuum Dark Energy and H
0 Tension

Published: November 2022

We study the effects of multiple transitions in the vacuum dark energy density on the H
0 tension problem. We consider a phenomenological model in which the vacuum energy density undergoes multiple transitions in the early as well as the late universe and compare the model’s predictions using the three sets of data from the cosmic microwave background, baryonic acoustic oscillations, and supernovae. The transient dark energy can be either positive (dS-like) or negative (AdS-like). We conclude that a transient late-time AdS-type vacuum energy typically yields the higher value of H
0, which can alleviate the H
0 tension. In addition, to obtain a value of H

A Data-constrained Magnetohydrodynamic Simulation of the X1.0 Solar Flare of 2021 October 28

Published: November 2022

The solar active region NOAA 12887 produced a strong X1.0 flare on 2021 October 28, which exhibits X-shaped flare ribbons and a circle-shaped erupting filament. To understand the eruption process with these characteristics, we conducted a data-constrained magnetohydrodynamics simulation using a nonlinear force-free field of the active region about an hour before the flare as the initial condition. Our simulation reproduces the filament eruption observed in the Hα images of GONG and the 304 Å images of SDO/AIA, and suggests that two mechanisms can possibly contribute to the magnetic eruption. One is the torus instability of the preexisting magnetic flux rope (MFR) and the other is upward pushing by magnetic loops newly formed below the MFR via continuous magnetic reconnection between two sheared magnetic arcades. The presence of this reconnection is evidenced by the SDO/AIA observations of the 1600 Å brightening in the footpoints of the sheared arcades at the flare onset. To clarify which process is more essential for the eruption, we performed an experimental simulation in which the reconnection between the sheared field lines is suppressed. In this case too, the MFR could erupt, but at a much reduced rising speed. We interpret this result as indicating that the eruption is not only driven by the torus instability, but additionally accelerated by newly formed and rising magnetic loops under continuous reconnection.

Introduction: The emergence and rapid spread of Enterobacteriaceae carrying extended spectrum beta-lactamases (ESBLs) and carbapenemases represent a great threat to clinical treatment due to their multi-drug resistance. This study investigated ESBLs and carbapenemases encoding genes in Enterobacteriaceae collected from diabetic foot infections (DFIs) in Ouargla, southern Algeria.

Methodology: A total of 70 Enterobacteriaceae strains were recovered from 76 patients with DFI between February 2017 and April 2018. Antimicrobial susceptibility testing was performed using the disc diffusion method, and the presence of bla genes was detected using polymerase chain reaction (PCR) and DNA sequencing. The genetic transfer of the plasmids was carried out by conjugation using the broth mating method.

Results: The most common isolate was Proteus mirabilis, followed by Escherichia coli, Morganella morganii and Klebsiella pneumoniae. The prevalence of ESBL and carbapenemase-producing Enterobacteriaceae was 11.42% and 2.85 % respectively. Plasmid-mediated AmpC was detected in 5.71% isolates. Conjugation experiments showed the transferability of blaCTX-M-2.

Conclusions: Our findings support the view that various pathogens found in DFIs differ from one part of the country to another. This study reports the first description of metallo-β-lactamase NDM-5 producing Klebsiella pneumoniae clinical isolate in Algeria.

Published: November 2022

Introduction: Malaria is a significant global health concern and adversely affects people in developing countries including Bangladesh. The causative agent Plasmodium falciparum is resistant to several currently available anti-malarial drugs, such as mefloquine, chloroquine, and artemisinin-based combination therapy (ACT), and this has been a major global challenge towards the control of the disease. There is urgent need for novel anti-malarial chemotherapeutic agents.

Methodology: The present study aimed to evaluate antimalarial activity of methanolic extracts of three Bangladeshi medicinal plants- Acorus calamus, Dichapetalum gelonioides and Leucas aspera - against both chloroquine sensitive (3D7) and resistant (Dd2) strains of P. falciparum. Histidine-rich protein 2 (HRP2) based ELISA was used to evaluate the in vitro inhibitory activity of the extracts.

Results: D. gelonioides extract showed moderate (IC50 = 19.15 µg/mL) and promising activity (IC50 = 10.43 µg/mL) against 3D7 and Dd2 strains respectively. A. calamus remained inactive against both 3D7 (IC50 = 72.29 µg/mL) and Dd2 strain (IC50 = 67.81 µg/mL). L. aspera initially remained inactive against 3D7 strain (IC50 = 60.51 µg/mL), but displayed promising activity (IC50 = 7.693) against Dd2 strain.

Conclusions: This is the first time these plant materials have been assessed for their in vitro antimalarial properties. It is pivotal to conduct further phytochemical analysis of D. gelonioides and L. aspera to evaluate the presence of potential novel antimalarial drug compounds.
A potential role of cockroaches in the transmission of pathogenic bacteria with antibiotic resistance: A scoping review
Authors: Luckyjane Molewa Mapula , Barnard Tobias , Naicker Nisha
Published: November 2022

Introduction: The role of cockroaches in the cause of disease or human infections is not immediately obvious. The present study aimed to review the currently available research on the potential role of cockroaches in the transmission of pathogenic bacteria and bacteria with antibiotic resistance.

Methodology: A scoping review included the studies published for a period between January 2001 and December 2020. A search was performed through five databases, namely, PubMed, Sage, Springer, Sabinet, and Science Direct. A search strategy used was conducted according to the principles of Preferred Reporting Item for Systemic Reviews and Meta-Analyses (PRISMA). From 97 studies identified, 32 studies were included in the scoping review.

Results: The findings indicate that cockroaches may be a potential vector for a diverse range of pathogenic bacterial agents. Most bacterial agents isolated are antidrug-resistant and antibiotic-resistant which is considered the greatest threat to public health in the current period.

Conclusions: Cockroach infestation should be considered as a serious concern, given the possible role of cockroaches as reservoirs of antibiotic-resistant bacteria. Further research is needed which can provide a comprehensive understanding of the role of cockroaches in transmitting human infections.

Peut-on démontrer qu’il est bon d’être né ? Il n’y a pas que Cioran pour dénoncer l’inconvénient de la chose, il y a aussi Job et Jérémie. Plutôt que d’une démonstration, il semble y aller plutôt d’un argument de convenance. Mais un tel argument marque les limites de la métaphysique devant le fait de la naissance humaine. Ce qui y est cherché n’est plus l’explication par une première Cause, mais la légitimation par un Père. Oublier cela, oublier la primauté du généalogique sur le logique, c’est fatalement verser dans ce qu’observe ce couple de penseurs qui n’eut pourtant pas d’enfants – Hannah Arendt et Günther Anders : le remplacement de l’être-né par l’être-fabriqué.

Published: November 2022

Purpose: The role of speculators in distributing products across rural areas is increasing the poverty rate in Indonesia. Therefore, this study aims to develop a conceptual framework of the rural logistics system model to influence the welfare and sustainability of farmers.Design/methodology/approach: Conceptual framework was used to evaluate logistics and supply chain networks. The method consists of developing stages based on four components, namely network structure, management, resources, and business processes. Furthermore, it also proposed the management function of the rural logistics system models.Findings: The model of a rural logistics system obtained in this study consists of 1) a trade  related to the network of business, 2) a freight, related to the flow of goods, and 3) management functions related to crucial activities in rural logistics management.Research limitations/implications: This model is conceptual, therefore, future studies must accommodate optimizing models to predict the performance of rural logistics systems when they are applied in Indonesia.Practical implications: This study promotes the actors in intermediaries of the rural logistics system to synergize the distribution of goods effectively and efficiently. It also reduces the role of speculators in product distribution in form of availability and price in rural areas.Social implications: This model is a strategy to achieve the Rural Sustainable development Goals (Rural-SDGs) agenda and complements the Blueprint of The National Logistics System.Originality/value: There are fewer studies in rural logistics compared to other fields such as agricultural logistics, food logistics, disaster logistics, etc. Therefore, this study organizes the actors in the rural logistics network and plans management functions for the efficient distribution of products across Indonesia. It also raises the awareness of logistics management to improve the welfare of rural communities.

Purpose: This study describes an empirical study demonstrating the application of circular economy (CE) to respond to an urgent call to reduce plastic waste by utilizing waste from the furniture industry.Design/methodology/approach: this study employed the measurements of environmental impacts of plastic and wood-based toothbrushes using a life cycle assessment, complemented by an analysis of the wood substitution design process from a CE perspective.Findings: The findings from this study not only shed light on quantifying the benefits of product valorization improvement and retention but also provide a means of weighing the value against raw materials and production costs.Research limitations/implications: The developed model is still limited to the use of waste to replace existing product materials. This study also did not include other industrial waste such as agro-industrial waste or other degradable materials which may open up many chances for further studies.Practical implications: The study’s primary contribution is a design rationale that assists the substitution of plastic material with wood waste, using toothbrushes as a case example of the substituted products.Social implications: This newly developed material can give potential income sources for the communities.Originality/value: The novelty of this study lies to the substitution model of non-degradable materials to a more environmentally-friendly material which is studied thoroughly from functional analysis, design alternatives, and evaluation based on environmental, economic, and social aspects especially in case of personal care products (toothbrush).

In this paper, we establish an integral equality involving a multiplicative differentiable function for the multiplicative integral. Then, we use the newly established equality to prove some new Simpson's and Newton's inequalities for multiplicative differentiable functions. Finally, we give some mathematical examples to show the validation of newly established inequalities.
A Boolean model for conflict-freeness in argumentation frameworks
Authors: Wu Jiachao
Published: November 2022

The Boolean models of argumentation semantics have been established in various ways. These models commonly translate the conditions of extension-based semantics into some constraints of the models. The goal of this work is to explore a simple method to build Boolean models for argumentation. In this paper, the attack relation is treated as an operator, and its value is calculated by the values of its target and source arguments. By examining the values of the attacks, a Boolean model of conflict-free sets is introduced. This novel method simplifies the existing ways by eliminating the various constraints. The conflict-free sets can be calculated by simply checking the values of the attacks.

Published: November 2022

This article is dedicated to Giuseppe Mingione for his $ 50^{th} $ birthday, a leading expert in the regularity theory and in particular in the subject of this manuscript. In this paper we give conditions for the local boundedness of weak solutions to a class of nonlinear elliptic partial differential equations in divergence form of the type considered below in (1.1), under $ p, q- $growth assumptions. The novelties with respect to the mathematical literature on this topic are the general growth conditions and the explicit dependence of the differential equation on $ u $, other than on its gradient $ Du $ and on the $ x $ variable.

Digital literacy is critical in the current era of digitalization. Therefore, students are required to be digitally literate. This study aims to improve students’ digital literacy using an android-based e-module in chemical bonding. This study used a quasi-experimental method with a pre-experimental design that included a pretest and posttest for one group. For this study, 70 preservice teachers (10 males and 60 females) from the Department of Chemistry Education at a private university in Indonesia were recruited. The Digital Literacy Questionnaire (DLQ) was used to measure students’ digital literacy. To analyze the data, we used paired t-tests and N-gain. The results indicated a significant increase in digital literacy scores before and after treatment. Thus, it can be concluded that using an android-based e-module significantly enhances students’ digital literacy on chemical bonds. Due to its effectiveness, we recommend teachers use this e-module to elevate students’ academic performance, in general, in chemistry.

Published: November 2022

This paper presents a simple approach to providing location-based services (LBSs) for the remotely located educational and health institutes on demand, particularly in emergency situations i.e., COVID-19, using an antenna array. The proposed approach consists of the sum and difference patterns of the signal obtained from the antenna array at the base station of a wireless network. It provides the location of the targeting institute i.e., education and health, in terms of the angle-of-arrival (AoA) which can be used to steer the radiation beam in the targeted direction in order to provide the desired services i.e., emergency wireless communication link. In this way, fast and high bandwidth-based communication and networking can be possible for the mentioned organizations. We show antenna array design and location finding results in this paper. The obtained results in terms of antenna parameters and AoA show that the proposed approach is efficient, less complicated, and can be implemented in the next-generation wireless networks i.e., AI-enabled IoT and 5G systems, particularly for the educational and health institutes.
