Authors: Hayakawa Hisashi , Hattori Kentaro , Sôma Mitsuru , Iju Tomoya , Besser Bruno P. , Kosaka Shunsuke
Published: December 2022

Solar activity generally exhibits cyclic behavior in terms of sunspot group number and sunspot positions every ≈11 yr. These sunspot data have therefore played key roles in numerous analyses of solar–terrestrial physics. However, their reconstructions prior to the 1830s have remained controversial and included significant data gaps, especially from the 1720s to the 1740s. Therefore, this study reviewed contemporary sunspot observations for 1727–1748 to add several forgotten records by Van Coesfelt in 1728–1729, Dûclos in 1736, Martin in 1737, and Cassini and Maraldi in 1748. On the basis of these records, this study revised the sunspot group number and newly derived the sunspot positions in this interval. The results show clearer solar cycles in sunspot group number than those of previous studies and indicate regular solar cycles with limited hemispheric asymmetry over Solar Cycles 0 to −2. The sunspot positions also show sunspot groups mostly at heliographic latitude φ fulfilling ∣φ∣ < 35° in both solar hemispheres, with slight equatorward motions. Furthermore, the solar minima between Solar Cycles −2 and −1 and between Solar Cycles −1 and 0 have been located around 1733.5 ± 0.5 and 1743 ± 0.5, indicating cycle lengths of 11.7 ± 0.5 yr and 10.0 ± 1.0 yr, respectively. Our results provide a chronological missing link between the Maunder Minimum and the regular solar cycles observed since Staudach’s observations from 1749 onward. This lets us better understand the transition of solar activity from the grand minimum to the regular solar cycles.
Vortex Pinning in Neutron Stars, Slipstick Dynamics, and the Origin of Spin Glitches
Authors: Link Bennett , Levin Yuri
Published: December 2022

We study pinning and unpinning of superfluid vortices in the inner crust of a neutron star using three-dimensional dynamical simulations. Strong pinning occurs for certain lattice orientations of an idealized, body-centered-cubic lattice and occurs generally in an amorphous or impure nuclear lattice. The pinning force per unit length is ∼1016 dyn cm−1 for a vortex–nucleus interaction that is repulsive and ∼1017 dyn cm−1 for an attractive interaction. The pinning force is strong enough to account for observed spin jumps (glitches). Vortices forced through the lattice move with a slipstick character; for a range of superfluid velocities, the vortex can be in either a cold, pinned state or a hot, unpinned state, with strong excitation of Kelvin waves on the vortex. This two-state nature of vortex motion sets the stage for large-scale vortex movement that creates an observable spin glitch. We argue that the vortex array is likely to become tangled as a result of repeated unpinnings and repinnings. We conjecture that during a glitch, the Kelvin-wave excitation spreads rapidly along the direction of the mean superfluid vorticity and slower in the direction perpendicular to it, akin to an anisotropic deflagration.

Authors: Nikolov Nikolay K. , Kovacs Aiden , Martlin Catherine
Published: December 2022

We present the Space Telescope Science Institute Wide Field Camera 3 (WFC3) project webpage, Transiting Exoplanets List of Space Telescope Spectroscopy, TrExoLiSTS. It tabulates existing observations of transiting exoplanet atmospheres, available in the MAST archive made with Hubble Space Telescope (HST) WFC3 using the stare or spatial scan mode. A parallel page is available for all instruments aboard James Webb Space Telescope (JWST) using the spectral Time Series Observation mode. The webpages include observations obtained during primary transits, secondary eclipses and phase curves. TREXOLISTS facilitates proposal preparation for programs that are highly complementary to existing programs in terms of targets, wavelength coverage, as well as reduces duplication and redundant effort. Reference for the quality of the HST WFC3 visits taken more than 1.5 yr ago are made available via including diagrams of the direct image, white light curve and drift of the spectral time series across the detector. Future improvements to the webpage will include: Expanding program query to other HST instruments and reference for the quality of JWST visits.
On the solvability of an initial-boundary value problem for a non-linear fractional diffusion equation
Authors: Arıbaş Özge , Gölgeleyen İsmet , Yıldız Mustafa
Published: December 2022

In this paper, we consider an initial-boundary value problem for a non-linear fractional diffusion equation on a bounded domain. The fractional derivative is defined in Caputo's sense with respect to the time variable and represents the case of sub-diffusion. Also, the equation involves a second order symmetric uniformly elliptic operator with time-independent coefficients. These initial-boundary value problems arise in applied sciences such as mathematical physics, fluid mechanics, mathematical biology and engineering. By using eigenfunction expansions and Banach fixed point theorem, we establish the existence, uniqueness and regularity properties of the solution of the problem.
Nexus among foreign direct investment, financial development, and sustainable economic growth: Empirical aspects from Sudan
Authors: Adam Mustafa Hassan Mohammad
Published: December 2022

This study examined the nexus between foreign direct investment (FDI), financial development, and sustainable economic growth in Sudan during the period of the structural adjustment program and the full Islamization of the banking and financial system that took place in the 1980s. The research provides a comprehensive analysis using the most recent time series secondary data from 1990 to 2020 and the study employed co-integration, Granger causality, and VAR error correction technique to estimate the models, to clarify the claimed relationship between FDI and its effect on the financial sector and subsequently attending a sustainable economic development in Sudan. In this research, Augmented Dickey-Fuller (ADF) unit root tests are applied to test the stationarity of data and the data was found stationary at first difference. The results of the ARDL bounds showed the existence of a long-term relationship between the FDI and other independent variables but the short-term showed otherwise. The Granger causality test implies that the past values of FDI don't significantly contribute to the prediction of sustainable economic growth. Also, results show that there's evidence of observed causality running from the country's trade openness and the financial sector's development. The implication of these results shows there is a complementary relationship between sustainable economic growth and both financial development and trade openness in the short run. Interestingly, the findings of the study show that the effect of financial development on economic growth is further enhanced by the inflows of FDI.

The world’s energy matrix can be diversified with biodiesel from castor and jatropha oil. Hence, the objective of this study was to assess a conversion path for the valorization of castor and jatropha seeds. The results showed the maximum extraction of castor oil at 90 °C, 2 rpm, and 6 mm nozzle, achieving a yield of 36.97% and for jatropha oil at 100 °C, 1.5 rpm, and 10 mm nozzle, achieving a yield of 20.11%. The acid value and cloud point of castor and jatropha oil were 0.797 and 23.44 mg KOH/g, 10±1 °C and 12±0.55 °C, respectively; while the pour point was -3 °C for both. The acid value and cloud point for biodiesels ranged from 0.26-0.43 mg KOH/g, and -12.50-6.10 °C, respectively. The viscosity of oils and biodiesel ranged from 0.02-1.3 P. GC-MS indicated 66.38% of methyl ricinoleate in castor biodiesel and 31.64% of methyl oleate in jatropha biodiesel. The HHV for castor and jatropha biodiesel ranged from 32.37-40.25 MJ/kg.
Super Inequality: A General Theory of Mass Poverty
Authors: Aspalter Christian
Published: December 2022

This study has set its goal to connect the dots and to build a unified general theory of inequality, which is capable of explaining the aggregate forces of historical, local, communal, national, and international systemic oppression and mass poverty at the same time. The super-super rich and super powerful are to blame and be held accountable for inequality, as they are the ones that have not only built the systems and forces that created inequality on an historical, intergenerational, and global scale but are also the ones maintaining those very systems and forces that create and worsen inequality and hence mass poverty on an appalling scale. The newly created theory of super inequality is aimed to gather and strengthen forces of science—and particularly, but not only, social policy—to be able, down the road, to tackle the perhaps greatest social problem of our time: inequality.
New Nationalism, Social Democracy, and Development: A Commentary on Contemporary India
Authors: Kodoor Suresh
Published: December 2022

As in the most parts of the world, India of today also is governed and determined by a socioeconomic order where the profit is privatized, while the cost is socialized. The world has been witnessing a vulgar polarization of wealth in favor of a few privileged with a vast majority of the populace getting pushed into the deeper ends of poverty and destitution. India is traversing this trajectory, more aggressively in the last couple of decades, since she opened up her economy to the forces of neo-liberalization. The worsening economic conditions would obviously trigger unrest and anger against those in power, and the ruling class in turn pre-empt the possibility of any such upraising by preoccupying the mass with emotionally charged divisive issues that pit them against one another. “Nationalism” has always been one of the most effective “emotional tools” in the hands of the rightist forces world over in the past in their efforts to ward off mass resistance, and now it is India’s turn to endure the enactment of the same. While capitalism is tightly preserving the economic structure that enables amassment of wealth for a few, fascism in the hands of the ultra-nationalists is acting as its gatekeeper to ensure that dispossessed do not gatecrash, revolt, and thrash the capitalist castle. The privileged work overtime to divide the very forces that could form a threat to their economic fortunes and system of loot. This paper is a detailed commentary on how the above said process is currently operating and how it is weakening the democracy, diversity, and sustainable development in India.

Published: December 2022

In this work, we question the practices of three first grade teachers in a basic problem-solving session. We identify the teaching skills and postures that emerge in the three practices based on the tools and methods developed by Bucheton. To explain the deep logic underlying the choices of these teachers, we analyze what each of them deploys in order to have a vision of the representations and strategies mobilized by their students to solve the problem posed. We specifically question certain didactical teaching skills that we see emerging and relate their capacity for transferability in a particular training framework.
La flexibilité des enseignants d’EPS dans la gestion d’imprévus relationnels et organisationnels
Authors: Pochon Sarah , Jelen Nathalie
Published: December 2022

Cet article rend compte de la flexibilité des gestes professionnels de deux enseignants d’EPS en poste dans un même établissement REP + lorsqu’ils font face aux imprévisibilités (relationnelle et organisationnelle) qui surviennent au cours des leçons. Mobilisant un cadre socio-didactique, les résultats montrent que les manières de s’ajuster aux imprévus en classe répondent à des intentions éducatives différenciées. Interrogeant les ressources plurielles mobilisées par les deux enseignants, l’enquête montre que si la dimension expérientielle joue un rôle dans les ajustements réalisés en classe, ce jugement expérientiel peut parfois être « erroné » et entraîner des limites d’efficacité dans les ajustements adoptés.

Authors: Filippi Pierre-Alain , Saujat Frédéric
Published: December 2022

Depuis la fin des IUFM, se sont succédé la masterisation (2010), les ESPE (2014) et les INSPE (2019). Ces réformes de la formation initiale des enseignants ont grandement transformé le travail des professionnels au sein de ces structures. En deçà des changements structurels, cet article s’intéresse au travail des formateurs à partir du grain fin de leur activité au sein de dispositifs prescrits par les réformes. Plus précisément, c’est à partir d’un épisode improvisé où une formatrice expérimentée, affectée par un échange entre pairs débutants, a tenté d’interrompre une situation de formation que nous mettons en évidence des conflits dans son activité d’ajustement provoqués par l’introduction non accompagnée de nouveaux dispositifs. Nous montrerons également comment un dispositif d’intervention-recherche a permis à un collectif de formateurs de revenir sur cette situation, d’en faire l’analyse et de s’engager dans un développement potentiel de leur activité d’ajustement d’en tirer des pistes potentielles de transformation de leur activité.

Authors: Pengiran Rosman Awangku Adi Putra
Published: December 2022

This chapter addresses digital footprints and how they can affect today's modern world, whether it be on the behaviour of humans, effects on society and governments, or even a person's ability to maintain their security or privacy. There is a possibility that leaving a digital footprint, regardless of the information that individuals post online, can have both positive and negative effects. The greater a person's digital footprint is, the more active they are in their interactions on the internet. It is necessary to bring attention to the matter at hand, which is the concept behind digital footprint being put into practise. It discusses digital footprints in a variety of contexts, such as real-life examples that illustrate how a digital footprint can have an impact in the actual world.

Authors: Pal Kamalendu
Published: December 2022

Technological innovation greatly supported global healthcare service in the recent coronavirus pandemic. The healthcare technical support came in two forms: (1) digitization of business functions and (2) development of new healthcare products. Healthcare-related data collection, preservation, and analysis using digital technologies support pandemic mitigation strategies. Gathering big data using the internet of things (IoT) technology, data analysis with the help of artificial intelligence (AI) techniques, mobile networking technologies for providing communication channels, and deploying the secure infrastructure are essential for the regular functioning of global healthcare services. In addition, healthcare operational data and infrastructure are highly vulnerable to traditional privacy and security-related issues. In addition, this chapter presents a survey of how security, trust, and privacy issues can deal with blockchain-based IoT computing architecture for securing healthcare information systems using lightweight cryptography.
A Review on the Pollination Services by Stingless Bees, Heterotrigona itama (Hymenoptera; Apidae; Meliponini), on Some Important Crops in Malaysia
Authors: Azmi Wahizatul Afzan , Wan Sembok Wan Zaliha , Hatta Muhammad Firdaus Mohd.
Published: December 2022

Stingless bees (Hymenoptera, Apidae, Meliponini) are common pollinators in the Malaysian agricultural ecosystem. Stingless bees are regarded as a good candidate for commercial pollination because of their specialized foraging adaptations and frequent visitation to cultivated fields. Unlike honeybees and bumble bees, stingless bees have not yet been commercially bred on a large scale for pollination purposes. Several studies outside Malaysia have shown that stingless bees' foraging activities may increase the production and quality of fruits. However, the role of stingless bees in producing quality fruits in open fields or in greenhouse crops in the Malaysian agricultural ecosystem is still unknown. In this review, the authors discuss the efficiency of stingless bees, Heterotrigona itama, pollination services on some important cultivated crops in Malaysia, namely chili (Capsicum annuum), cucumbers (Cucumis sativus), and rock melon (Cucumis melo) based on previous reports. The findings revealed that pollination by H. itama can increase fruit size and weight, seed number, and pericarp volume.

Authors: Agus Ali , Agussalim Agussalim
Published: December 2022

Domestication and propagation in stingless bees is called meliponiculture. The aims of meliponiculture are to make it easier to control the colonies health and development and to make it easy when harvesting stingless bee products (honey, bee bread, and propolis), furthermore, for advanced study and development like multiple colonies, to produce honey, bee bread, and propolis. Therefore, this paper focuswa on stingless bees Tetragonula laeviceps: the domestication and propagation technique, production of stingless bee products (honey, bee bread, and propolis), the daily activity of workers (foragers), the chemical composition (glucose, fructose, sucrose, reducing sugar, moisture, protein, ash, phenolic, flavonoid, vitamin C, antioxidant activity, minerals content, and amino acids) of honey from T. laeviceps, the pests and the challenges in meliponiculture of stingless bees.
Enacting Lifelong Learning in China
Authors: Li Shuyan , Torrisi-Steele Geraldine
Published: December 2022

In the last few decades, lifelong learning has gained favour as an educational paradigm. Inevitably, embedded in social, cultural, and economic contexts, the conceptualization and implementation of lifelong learning across the globe is far from homogenous. In China, although the notion of lifelong learning can be traced to Confucius, the term was introduced more formally in the late 1970s after the Cultural Revolution. In the present article, the authors engage in a critically reflective discussion of the lifelong learning in China. The authors offer historical and future perspectives on lifelong learning and how it is enacted in relation to labor distribution, skills, training, and future needs.
Investigating the Classroom Environment With Physical Computing
Authors: Parsons David , MacCallum Kathryn
Published: December 2022

To integrate digital technologies into the curriculum, teachers must support learners to use digital tools in authentic contexts. Physical computing, which involves the use of small portable electronic devices, provides an opportunity to achieve these goals. This article reports on the initial stages of a design-based research (DBR) project that will enable students to monitor and investigate their own learning spaces, with a focus on the impacts on their own well-being, and to propose solutions to any issues that they identify. The study focuses on a series of workshops, run with staff from an educational organisation, designed to explore environmental monitoring in the classroom and identify opportunities to apply the theory of situated cognition to authentic learning in context. The article reports on the first two phases of the DBR approach, defining the project focus and understanding the problem, to propose and refine a set of five design principles. The insights gained will be used in the subsequent phases of the DBR process.

Self-assembly and mineralization of type I collagen (Col) with nanocrystalline apatite (nAp), by adding a solution of Ca(OH)2 to a stirred Col-H3PO4 solution by fast dripping, allowed the preparation of Col/nAp fibrils with good crystallographic control of the mineral phase. In this work, in addition, we have cross-linked the mineralized fibers by using different reagents, namely glutaraldehyde (GTA), tannic acid (TA), 1-Ethyl-3-(3-dimethyl aminopropyl)-carbodiimide combined with N-Hydroxysuccinimide (EDC/NHS), and genipin (GP), aimed at producing different types of biopolymeric Col/nAp-based drug delivery scaffolds. In parallel, we have investigated two different methods to impregnate the scaffolds with molecules of the cocrystal diclofenac-metformin (DF-MET). The result, when using TA as a crosslinking reagent, shows the sequence of mineralized fibrils impregnation followed by crosslinking leads to maximum cocrystal molecule loading. The impregnated material is expected to be useful in settings with excessive and prolonged inflammation, since they affect negatively the fracture healing/bone repair processes, especially during the early stages of healing.

Published: December 2022

Calcium phosphate is a natural biomineral and the major inorganic constituent of bones and teeth. Therefore, synthetic calcium phosphates that mimic the biogenic ones possess excellent biocompatibility as well as biodegradability and are promising materials for medicine. Due to their unique physiochemical properties, calcium phosphate nanoparticles (CaP NPs) are extensively exploited in nanomedicine as carriers of biomolecules, including peptides, proteins, and nucleic acids. In this regard, peptides are of particular interest as they are exceptionally selective and efficacious for the treatment of a broad range of diseases. Among various peptides for biomedical applications, cardio-specific peptides are particularly interesting since they represent a valuable alternative to conventional treatments. Moreover, they can contribute to overcome important clinical limitations, including drug resistance and non-specific biodistribution of traditional drug products. In this work, we have investigated the loading of a therapeutic mimetic peptide, which was previously shown to improve myocardial contraction and results in the restoration of cardiac function. Peptide-loaded CaP NPs were prepared by exploiting a biomineralization approach, by using a mineralizing solution containing Ca2+, Mg2+, and PO43- ions. Several experimental conditions were tested by varying the reaction time, as well as the drug concentration. Colloidal stability, morphology, size, as well as drug loading were evaluated to identify the best candidate to be tested in vitro in the future.

Published: December 2022

Hydroxyapatite (HA) ceramic scaffolds are commonly used as bone graft substitutes. Design of such scaffolds is a challenge to improve biological properties and extend the applications of HA ceramics in the field of bone tissue engineering. In this work, we investigated the processing and the in vitro properties of HA ceramic scaffolds mimicking human trabecular bone architecture. Samples of human tibial trabecular bone were collected (University Hospital Center of Limoges) and scanned by X-Ray μ-computed tomography (μ-CT) to generate 3D model database. From this computer-aided design, HA ceramic scaffolds were shaped layer-by-layer by additive manufacturing using laser stereolithography (SLA). Then, green parts were sintered to obtain dense ceramic scaffolds. The shaped parts were compared to the model (wall thickness, size, and geometry of the porous network) using image analysis. A good agreement was found. Only small differences were detected due to a light overpolymerization or to some unprinted very small details that were not linked to a polymerized area of the previous layer. Due to part shrinkage during sintering a magnifying factor has to be applied to the scanned CAO model to match the real dimensions of the trabecular bone sample. Human mesenchymal stem cell (hMSC) cultures were performed to investigate the biological properties of these scaffolds (cell attachment and proliferation of hMSC). These preliminary biological evaluations show the good biocompatibility and cell adhesion of the HA substitute. This work evidences the efficiency of SLA to produce ceramic scaffold architectures mimicking that of the natural trabecular bone with promising biological behavior.

Published: December 2022

Background

and

Aim:

To evaluate the association between psychoacoustical characteristics of tinnitus and audiogram configurations and reveal which theoretical mechanism dominates tinnitus.

Materials and Methods:

The medical charts of 110 adult participants' 164 ears with tinnitus were retrospectively reviewed. Audiological results, edge frequency, and psychoacoustical characteristics of tinnitus were assessed. Participants were divided into two groups as follows: normal hearing (NH) and sensorineural hearing loss (SNHL).

Results:

No significant relationship was observed between age, gender, tinnitus pitch, and loudness between the two groups. In the SNHL group, there was a weak positive correlation between tinnitus pitch and frequency of maximum hearing loss (FMHL), and a strong positive correlation between the mean tinnitus loudness at the tinnitus pitch and FMHL. Besides, the edge frequency was positively and weakly correlated with the tinnitus pitch and FMHL. No statistically significant difference was observed between the groups regarding the tinnitus pitch. However, tinnitus loudness was statistically higher in the NH group. No relationship was observed between the audiogram shapes and tinnitus timbre, pitch, and FMHL. In addition, the most likened tinnitus timbre was found to be tonal/whistle in both groups. A moderate positive correlation was observed between the tinnitus pitch and edge frequency in the gradual slope audiograms.

Conclusions:

The findings obtained in this study supported homeostatic plasticity theories for the SNHL group, and hidden hearing loss for the NH group.
Neuroanatomical and Etiological Approaches to Secondary Narcolepsy
Authors: Senel Gulcin Benbir , Karadeniz Derya
Published: December 2022

Narcolepsy is one among the disorders of central hypersomnolence characterized by excessive daytime sleepiness not related to disturbances in nocturnal sleep or misalignment in circadian rhythms. The cardinal symptom of this group of disorders is disabling daytime sleepiness, characterized by the repeated episodes of irresistible daytime sleepiness or lapses into sleep in monotonous situations, but also under unusual conditions such as eating. Narcolepsy is defined as type 1 and type 2 on the basis of the presence of cataplexy. The most pathognomonic feature of narcolepsy type 1 is cataplexy, which is characterized by sudden episodes of brief loss of muscle tone-sparing consciousness, usually triggered by strong emotions. Other nonspecific symptoms associated with rapid eye movement sleep dissociation include fragmentation of nocturnal sleep, hypnagogic or hypnopompic hallucinations, and sleep paralysis. The pathophysiology of narcolepsy type 1 is well established as the deficiency of hypocretin (orexin) signaling in the lateral hypothalamus. In narcolepsy type 2, on the other hand, hypocretin levels are not decreased, and it has been suggested that there is probably a partial deficiency in hypocretin signaling system to cause excessive daytime sleepiness but not severe enough to cause cataplexy. Instead of types 1 and 2, primary (idiopathic) narcolepsy, familial narcolepsy, secondary (symptomatic) narcolepsy, and narcolepsy plus (hereditary forms with additional neurological symptoms) forms were suggested to better classify the clinical entities. In this paper, the diagnosis of symptomatic or secondary narcolepsy is reviewed and classified based on the underlying pathophysiologic mechanisms.

Published: December 2022

Anopheles darlingi is the main vector of malaria in South America. In French Guiana, malaria transmission occurs inland and along the rivers with a regular reemergence in the lower Oyapock area. Control against malaria vectors includes indoor residual spraying of deltamethrin and the distribution of long-lasting impregnated bednets. In this context, the level of resistance to pyrethroids was monitored for 4 years using CDC bottle tests in An. darlingi populations. A loss of susceptibility to pyrethroids was recorded with 30-minute knock-down measured as low as 81%. However, no pyrethroid molecular resistance was found by sequencing a 170 base pair fragment of the S6 segment of domain II of the voltage-gated sodium channel gene. Fluctuation of resistance phenotypes may be influenced by the reintroduction of susceptible alleles from sylvatic populations or by other mechanisms of metabolic resistance.
Socioeconomic Status of Guardians as a Risk Factor for Canine Visceral Leishmaniasis: A Cohort Study in an Endemic Area of the Federal District, Brazil
Authors: Marcolino Silva Debora , Passarella Teixeira Ana Izabel , Sierra Romero Gustavo Adolfo
Published: December 2022

Current control measures of canine visceral leishmaniasis (CVL), a chronic and fatal zoonosis with potential transmission to humans, are not efficient enough to reduce its spread. The search for improved control measures should include studies of risk factors for infection and illness. This study aimed to identify the risk factors for CVL in an endemic locality of the Federal District, Brazil, from June 2016 to December 2018. Biologic samples and data on dog characteristics, owner household characteristics, and dog care were collected. A combination of serological and molecular tests was used to identify infected animals. The 248 dogs screened for inclusion were predominantly asymptomatic/oligosymptomatic. The baseline prevalence of infection was 27.5%. One hundred six of 162 susceptible dogs were monitored for an average period of 10.7 months. The estimated CVL incidence was 1.91 cases/100 dog-months. The multivariate analysis using a proportional Cox model included the potential risk factors, with P ≤ 0.25 in the univariate analyses. Greater purchasing power (hazard ratio [HR], 1.04; 95% CI, 1.01–1.06; P = 0.03) and paved yard (HR, 0.19; 95% CI, 0.13–1.01; P = 0.05) remained in the final model as risk and protection factors, respectively. The use of repellent collars in dogs was associated moderately (P = 0.08) with protection against CVL. Our findings reflect the challenge of identifying strong interventions for reducing CVL incidence. Increased owner wealth had a counterintuitive effect on CVL, making the intervention scenario more complex for a zoonosis traditionally associated with poverty.
Language Maps from Africa to Europe
Authors: Al Hosani Naeema
Published: December 2022

Language maps, which reflect linguistic pluralism, multilingualism and the spread of languages across countries and empires were part of an evolving human history. Historically, language came under the impact of geography, political conflicts and colonization. Due to these factors, languages penetrate borders or ended up in isolation or even in extinction. In this context, the paper investigates selected language maps of many African, Asian, European and South American countries in order to underline the connections between language, politics, immigration, war and other related elements. The paper argues that current language maps in some geographical regions are similar to the political maps of the nineteenth and early twentieth centuries because colonial languages continued to exist in these countries even after the departure of the colonizers. Further, the paper explores the spread of a variety of languages and their penetration in some countries, which constituted a great part of the European Union, in order to examine the impact of geo-politics on the changing status of language maps in Europe.

Published: December 2022

Nanocomposites assembled with TiO2 and graphene were synthesised under solvent free conditions. The calcinated nanocomposites have been characterized by PXRD, SEM-EDAX, HRTEM and Nitrogen adsorption-desorption techniques. Nanotitania was found to be formed in anatase phase with larger surface area (268.2 m2g-1) and with increase in graphene content, the absorbance increased towards visible region. Their biological applicability has been evaluated by examining their anti-bacterial activity against E. coli (ATCC29181), S. aurues (ATCC6538) and their anti-fungal activity against C. albicans, C. rugosa (ATCC10231) organisms. It has been observed that the biological activity has increased with increase in % graphene from 0.1 to 0.5 and showed a steady decrease with 1.0 % graphene.

Comportamiento kantiano y equilibrio cooperativo durante la pandemia
Authors: VITE TISCAREÑO IVONNE , Sánchez Buelna Pablo
Published: December 2022

Este artículo analiza el comportamiento estratégico de los individuos durante la pandemia y con ello dar una posible explicación de porque algunas normas sanitarias poco restrictivas fueron exitosas en algunos países, mientras que en otros países tuvieron que aplicar diferentes medidas con incentivos positivos o negativos, para lograr que se redujeran los contagios. Se estudian dos distintos tipos de estrategias, la estrategia kantiana y la racional. Se define como estrategia kantiana a los agentes que siguen una norma social, donde se basa en la reciprocidad de las personas y tiene como consecuencia que los individuos internalizan las externalidades que generan a los demás, mientras que el comportamiento racional busca la maximización propia, tomando como dado el comportamiento de los demás. Se comparan los equilibrios kantianos y los de Nash y se encuentra en qué condiciones, a pesar de ser distintas estrategias, llegan al mismo equilibrio y en cuales otras circunstancias se llegan a equilibrios muy distintos. Finalmente, se analizan ambas estrategias, para entender la aplicación de las políticas sanitarias en diferentes países durante la pandemia. Se encuentra que cuando los agentes siguen la estrategia kantiana, se puede sostener un equilibrio cooperativo, sin necesidad de otro incentivo, mientras que cuando los agentes se comportan de manera racional, necesitan incentivos positivos o negativos, para no desviarse del equilibrio socialmente óptimo.

A robotics and Internet of Things (IoT) combination is the foundation of the surveillance robot. Using a remote control, the user can manage the robot. The robot moves and broadcasts live video in response to user instructions. The Raspberry Pi's microprocessor is used to direct robot movement. In order to deliver live video content that people may view, the robot must travel around a given region. As a consequence, monitoring is done. Numerous industries, including defence, healthcare, apartment security, and others have numerous uses for the surveillance robot. When under risky conditions, a person cannot work. These situations and places include a burning structure, a region with hazardous chemicals or radiation, and a war. An unsuccessful surveillance system was created
and put into use.

The conventional version with effective and negative waveform is broadly utilized in electrostatic purifier studies. Dust elimination efficiencies and electric losses for exceptional frequency and voltage values have been in comparison for each card. It has been proven that the proposed version can carry out cleansing with excessive
performance in spite of comparable loss variation.
Women Entrepreneurship: Vocal for Local
Authors: Priya Gupta  , Divya Dwivedi
Published: December 2022

Vocal for Local is not a new concept in India. It began as a revolution during the Gandhian English periods when English goods were exploited and thrust was given to Indian local goods to protect Indian culture and ethics and to retain India’s economy. The goal of vocal for locals is to support local small entrepreneurship and to create a nurturing atmosphere for them to reach their full potential inside the country. India has historically been a country with abundant natural resources. We may lack sophisticated technical advancement, but nature's support is abounded. It is possible to utilize
our local products and avoid foreign products and their brands if we have alternatives available in our home country. If we can support each other in our home country, then self –reliance becomes possible. This will automatically increase the country’s wealth by not importing; reduce the dependency of the foreign country and also the mobilization of local goods to other foreign countries. With the support of our country’s local product, it will have future possibility local for global. This research paper will
provide the direction to develop the identity of local brands. Despite the hardships we've all endured in recent months as a result of the lockdown, both existing and aspiring entrepreneurs are focused on their businesses that aren't influenced by outside forces. Women are firmly moving ahead when it comes to defying preconceptions and pushing boundaries. By starting their own business, they are reinventing professional routes and carving out a niche for themselves. In many ways, India's food industry reflects the nation's extensive geographical, cultural, and agricultural variety. In terms of its contribution to GDP, employment, and investment, the food processing segment is one of the key segments of the Indian economy. This industry has had a booming growth throughout the five years ending in 2018–19.

Published: December 2022

Indian Railways is the largest public sector undertaking in India but suffers from a major problem of inefficient waste management system. This is a problem of dry and wet waste generated inside the running train and around the railway tracks resulting in unhygienic trains and unclean railway tracks. Everyday nearly 23 million people travel in 7000 passengers trains inIndia. The area around the railway track in India is about 16000 kms which has never been cleaned. It is estimated that approximately 6289 tons of plastic finds its way into India’s railway tracks every day. This enormous generation of waste is leading to undesirable health issues besides environmental pollution. In this
backdrop, in this project a prototype technological modelis being developed which can help to solve this problem. A smart dustbin is placed in each compartment of all the bogies in a train wherein both the dry and wet waste are collected, segregated and crushed. With the help of the belt conveyor, this crushed dry and wet waste is carried from all the compartments and bogies to the centralized bin of the train. This technological prototype model facilitates to manage the enormous dry and wet waste
generated inside the running train effectively and efficiently. This will benefit the recycling industries to generate the revenue besides helping to keep the trains and railway tracks clean.
