Authors:   Institute of Solid State Chemistry of the Ural Branch of RAS, Pasechnik Liliya A.
Published: May 2023

The results of the scandium behavior in sulfate systems obtained during the processing of alumina production red mud were presented. It is shown that ammonium sulfoscandate NH4Sc(SO4)2 crystallizing under the chosen conditions has great prospects as a gravimetric form. The precipitation of NH4Sc(SO4)2 has a high selectivity in the separation of scandium from other components of solutions, as evidenced by the higher separation factors between scandium and impurities of the most common metals βSc/M (for example, for a pair with aluminum βSc/Al = 4280). Additionally, the possibility of selective precipitation of a less soluble double salt KSc(SO4)2 has been established. The product of recrystallization and calcination contains 99% Sc2O3.

A brief comparative analysis of the existing methods of electrolytic production of silicon is made. The advantages and disadvantages of the electrolytes used based on molten salts and organic solvents are noted. It is shown that the greatest attention is paid to the principal possibility of electrolytic production of silicon mainly from KCl — KF melts with K2SiF6 and SiO2 additives, as well as from CaCl2 — CaO melts with SiO2 and CaSiO3 additives. The results of electrodeposition from low fluoride systems based on chlorides with the addition of K2SiF6 are presented, and tasks for the further practically oriented development of silicon electrochemistry are listed.
Epistemological assumptions of age-friendly cities: a scoping review
Authors:   Universidade de Brasília, Brasília, DF, Brazil., Maciel Tatiana Frade , Leides Barroso Azevedo Moura
Published: May 2023

Objective: To identify the concepts and theoretical perspectives that underlie studies on age-friendly city. Methods: This is a scoping review using six databases to identify studies published in indexed journals between 2007 and 2021 using the keywords ‘age-friendly’ OR ‘age friendly’ OR ‘cidade amiga’. Results: A total of 2,975 studies were found, which, after applying the exclusion criteria, resulted in 227. There was wide variation in the concept of the term, but many authors did so by replicating the WHO, and in 59.5% of studies there was no mention of any theoretical perspective. The ecological theory was the most frequent reference (26%), the term being used as an equivalent to active aging. Authors from four countries account for most articles (61%). Conclusion: It is necessary to articulate the concept of age-friendly city with a theoretical and cultural approach to understand more deeply the urban and social perspectives under the logic of population aging, mainly for Latin America. Theoretical analysis in these studies and in gerontology will favor more critical discussions about aging, ageism and the growing social inequality in progress.

OPTIMAL GERMINATION METHODS, ORNAMENTAL PLANT FEATURES, AND EX SITU CONSERVATION OF ENDEMIC CAMPANULA GRANDIS FISCH & C.A. MEY
Authors: Yücel Gül , Erken Kamil
Published: May 2023

This study aimed to investigate the ornamental utilization, two-year growth performance in natural habitat and cultural conditions, generative production methods, and morphologic and phenologic plant properties of Campanula grandis, which is an endemic species demonstrating ornamental plant potential and needs ex-situ conservation and cultivation. In addition, the germination and growth performance of seeds collected in the new season was compared with seeds that were kept for one year. Seeds stored dry for 3 months at 4 °C and then treated with 200 ppm GA3 exhibited the highest germination percentage (76%). Furthermore, GA3 treated seeds had best germination speed, shortening the germination time. This study also identified the ideal temperature for germination as 20 °C for the best germination rate. It was revealed that the number of flowers on the plant in natural habitat was 48 while in cultural conditions it was found as 165 flowers in biennial plants. The seedlings were planted in an ex-situ collection garden established for placing the Campanula grandis species under conservation. The Campanula grandis species has the potential for use as an ornamental plant for landscaping applications due to its lengthy flowering period, vigorous second-year stem growth, and numerous, enormous, flamboyant, blue-purple, and bell-shaped flowers.
Chemical Compositions Of Red Giant Stars in the Old Open Cluster NGC 7789

Published: May 2023

We have gathered optical-region spectra, derived model atmosphere parameters, and computed elemental abundances for 15 red giant stars in the open cluster NGC 7789. We focus on the light element group CNOLi that provides clues to evolutionary changes associated with internal fusion events and chemical mixing. We confirm and extend an early report that NGC 7789 stars 193 and 301 have anomalously large Li abundances, and that these values are apparently unconnected to any other elements’ abundances in these stars. A companion study of He i
λ10830 lines in both field stars and cluster members shows that star 301 has a strong He feature while star 193 does not. Possible explanations for the large Li abundances of these stars include helium flash-induced mixing events and binary interactions at some past or present times. In either case an internal eruption of energy could cause fresh synthesis of lithium via the Cameron-Fowler Berillyum transport mechanism. Rapid transport of lithium to the outer layers may have created significant chromospheric transient disturbances, producing enough helium ionization to allow for the strong λ10830 absorption in star 301.
Observing Atmospheric Escape in Sub-Jovian Worlds with JWST
Authors: Dos Santos Leonardo A. , Alam Munazza K. , Espinoza Néstor , Vissapragada Shreyas
Published: May 2023

Hydrodynamic atmospheric escape is considered an important process that shapes the evolution of sub-Jovian exoplanets, particularly those with short orbital periods. The metastable He line in the near-infrared at 1.083 μm is a reliable tracer of atmospheric escape in hot exoplanets, with the advantage of being observable from the ground. However, observing escaping He in sub-Jovian planets has remained challenging due to the systematic effects and telluric contamination present in ground-based data. With the successful launch and operations of JWST, we now have access to extremely stable high-precision near-infrared spectrographs in space. Here we predict the observability of metastable He with JWST in two representative and previously well-studied warm Neptunes, GJ 436 b (T
eq = 687 K, R
p = 0.37 R
J) and GJ 1214 b (T
eq = 588 K, R
p = 0.25 R
J). Our simulated JWST observations for GJ 436 b demonstrate that a single transit with NIRSpec/G140H is sensitive to mass-loss rates that are two orders of magnitude lower than what is detectable from the ground. Our exercise for GJ 1214 b show that the best configuration to observe the relatively weak outflows of warm Neptunes with JWST is with NIRSpec/G140H, and that NIRSpec/G140M and NIRISS/SOSS are less optimal. Since none of these instrument configurations can spectrally resolve the planetary absorption, we conclude that the 1D isothermal Parker-wind approximation may not be sufficient for interpreting such observations. More sophisticated models are critical for breaking the degeneracy between outflow temperature and mass-loss rate for JWST measurements of metastable He.
Explosion Mechanism of Core-collapse Supernovae: Role of the Si/Si–O Interface
Authors: Boccioli Luca , Roberti Lorenzo , Limongi Marco , Mathews Grant J. , Chieffi Alessandro
Published: May 2023

We present a simple criterion to predict the explodability of massive stars based on the density and entropy profiles before collapse. If a pronounced density jump is present near the Si/Si–O interface, the star will likely explode. We develop a quantitative criterion by using ∼1300 1D simulations where ν-driven turbulence is included via time-dependent mixing-length theory. This criterion correctly identifies the outcome of the supernova more than 90% of the time. We also find no difference in how this criterion performs on two different sets of progenitors, evolved using two different stellar evolution codes: FRANEC and KEPLER. The explodability as a function of mass of the two sets of progenitors is very different, showing: (i) that uncertainties in the stellar evolution prescriptions influence the predictions of supernova explosions; (ii) the most important properties of the pre-collapse progenitor that influence the explodability are its density and entropy profiles. We highlight the importance that ν-driven turbulence plays in the explosion by comparing our results to previous works.
Diffuse Emission of Galactic High-energy Neutrinos from a Global Fit of Cosmic Rays
Authors: Schwefer Georg , Mertsch Philipp , Wiebusch Christopher
Published: May 2023

In the standard picture of Galactic cosmic rays, a diffuse flux of high-energy gamma rays and neutrinos is produced from inelastic collisions of cosmic-ray nuclei with the interstellar gas. The neutrino flux is a guaranteed signal for high-energy neutrino observatories such as IceCube but has not been found yet. Experimental searches for this flux constitute an important test of the standard picture of Galactic cosmic rays. Both observation and nonobservation would allow important implications for the physics of cosmic-ray acceleration and transport. We present CRINGE, a new model of Galactic diffuse high-energy gamma rays and neutrinos, fitted to recent cosmic-ray data from AMS-02, DAMPE, IceTop, as well as KASCADE. We quantify the uncertainties for the predicted emission from the cosmic-ray model but also from the choice of source distribution, gas maps, and cross sections. We consider the possibility of a contribution from unresolved sources. Our model predictions exhibit significant deviations from older models. Our fiducial model is available at https://doi.org/10.5281/zenodo.7859442

Predicting Short-duration GRB Rates in the Advanced LIGO Volume
Authors: Dimitrova Tzvetelina A. , Butler Nathaniel R. , Ravi Srihari
Published: May 2023

Starting with models for the compact object merger event rate, the short-duration gamma-ray burst (sGRB) luminosity function, and the Swift-BAT detector, we calculate the observed Swift sGRB rate and its uncertainty. Our probabilistic sGRB world model reproduces the observed number distributions in redshift and flux for 123 Swift-BAT detected sGRBs and can be used to predict joint sGRB/LIGO detection rates. We discuss the dependence of the rate predictions on the model parameters and explore how they vary with increasing experimental sensitivity. In particular, the number of bursts in the LIGO volume depends strongly on the parameters that govern sGRB beaming. Our results suggest that nearby sGRBs should be observed to have broader jets on average (θ
jet ≳ 30°), as compared to the narrowly beamed appearance of cosmological sGRBs due to the detection-selection effect driving the observed jet angle. Assuming all sGRBs are due to compact object mergers, within a D < 200 Mpc aLIGO volume, we predict

Published: May 2023

Connecting the solar wind observed throughout the heliosphere to its origins in the solar corona is one of the central aims of heliophysics. The variability in the magnetic field, bulk plasma, and heavy ion composition properties of the slow wind are thought to result from magnetic reconnection processes in the solar corona. We identify regions of enhanced variability and composition in the solar wind from 2003 April 15 to May 13 (Carrington Rotation 2002), observed by the Wind and Advanced Composition Explorer spacecraft, and demonstrate their relationship to the separatrix–web (hereafter, S-Web) structures describing the corona’s large-scale magnetic topology. There are four pseudostreamer (PS) wind intervals and two helmet streamer (HS) heliospheric current sheet/plasma sheet crossings (and an interplanetary coronal mass ejection), which all exhibit enhanced alpha-to-proton ratios and/or elevated ionic charge states of carbon, oxygen, and iron. We apply the magnetic helicity–partial variance of increments (H

m
–PVI) procedure to identify coherent magnetic structures and quantify their properties during each interval. The mean duration of these structures are ∼1 hr in both the HS and PS wind. We find a modest enhancement above the power-law fit to the PVI waiting-time distribution in the HS-associated wind at the 1.5–2 hr timescales that is absent from the PS intervals. We discuss our results in the context of previous observations of the ∼90 minutes periodic density structures in the slow solar wind, further development of the dynamic S-Web model, and future Parker Solar Probe and Solar Orbiter joint observational campaigns.
On the Recent Discovery of Coronal [Fe x]λ6374 Emission in the Low-metallicity Dwarf Galaxy SDSS J0944-0038

Published: May 2023

Coronal emission lines, especially the [Fe x]λ6374 line, are now being used as tracers for intermediate mass black holes (IMBHs) in low-mass galaxies. We show that the recent discovery of [Fe x]λ6374 emission in the metal-poor starburst SDSS J094401.87-003832.1 by Reefe et al. is, in fact, a misidentified line. The line interpreted as [Fe x]λ6374 is Si ii
λ6371. We caution that current and future campaigns hunting for IMBHs with the [Fe x]λ6374 line need to account for possible contamination by Si ii
λ6371 emission.

Published: May 2023

Objective: This diagnostic study aims to determine the expression of salivary IEX-1 as a predictor of malignancy in epithelial ovarian tumors.  
Methods: Samples were obtained from ovarian cancer patients who were scheduled for elective surgery. Patients' saliva was collected before surgery and used as the study's research material. Research subjects who met the inclusion and exclusion criteria were divided into two groups based on the post-operative histopathological results, benign and malignant epithelial ovarian tumors. The salivary IEX-1 expression was examined using the Real Time qPCR method. We compared and analyzed the salivary IEX-1 expression ​​in benign and malignant epithelial ovarian tumors.  
Results: The results of this study were obtained from 47 epithelial ovarian tumors subjects, 22 malignant tumors and 27 benign tumors. The mean salivary IEX-1 expression in benign epithelial ovarian tumors was higher (1.976) than the malignant tumors (0.554) (p<0.001). The AUC value of IEX-1 expression was 0.949 (95% CI 0.894-1,000), cut off point of salivary IEX-1 is ≥ 0,9115 with sensitivity 84%, specificity 86,4%, positive predictive value 82.6% and negative predictive value 87.5%. There was a significant correlation between salivary IEX-1 expression and malignant epithelial ovarian tumors with an OR 5.031 (95% CI 2.039-12.4; p<0,001)
Conclusion: Salivary IEX-1 expression declines in tandem with the development of malignant epithelial ovarian tumors, providing a very sensitive and specific indicator of the presence of these malignant tumors.
Keywords: Expression of IEX-1, Malignant epithelial ovarian tumor, Salivary IEX-1, Tumor Marker.

The purpose of this study is to perform a zoogeographic analysis of terrestrial true bugs (Heteroptera) in the Lower Amudarya Territory, Uzbekistan. According to the findings of a literature review, there are 149 species of terrestrial hemipterans in the Territory. All hemipteran species, with the possible exception of five, have most likely been misidentified. Until now, reliable information on the zoogeography of true bug species in Uzbekistan’s north-western region has not been published. The composition of species, diversity, and the proportion of endemism vary greatly across the country’s zoogeographic regions. The Heteroptera fauna of the Khorezm and Karakalpakstan can be divided into four groups: most species belonging to the Palaearctic region, with 125 species constituting 83.89% of the fauna; the second group of Holarctic origin is characterized by no more than ten species, which constitutes 6.71%; the third consists of endemics, 13 species or 8.72%; and one species (0.67%) is cosmopolitan. Much more research is needed to investigate distributions in a more northern climate. The introduction of invasive Heteroptera to the north-western part of Uzbekistan will increase and deserves further consideration.

L’article rend compte de différents modes d’appréhensions culturelles de la toute première vague de pandémie COVID-19 et des mécanismes d’adaptation subséquents en Inde, au Bangladesh, au Japon, en Syrie, en Nouvelle-Zélande, en Afrique du Sud, au Kenya, en Tunisie, au Salvador, aux États-Unis, en Italie et en Belgique. La culture influence la façon dont une épidémie touche la société, selon l’interprétation de son origine, son mode de propagation et de traitement, ainsi que les réponses à la détresse et les pratiques de santé. Les réponses culturelles à la pandémie contribuent à en contrôler ou accélérer la propagation, voire à unir ou diviser certains secteurs de la société. La culture influence aussi la perception des interventions médicales et donc la présence ou l’absence de demandes d’aide aux services de santé. Les réponses culturelles variées soulignent l’importance de la culture en santé publique, en particulier en cas de crise, dans le choix des mesures sanitaires. Enfin, au creux de la première vague pandémique, l’expérience de rassembler des témoignages d’acteurs de cultures différentes a permis de tisser un lien au sein d’une « jeune » génération de psychiatres vivant dans différentes parties du globe, et les a aidés à faire face au potentiel traumatique du risque d’isolement et de repli, face aux défis de leurs contextes professionnels respectifs.

Droits des femmes, bioéthique et procréation médicalement assistée : perspectives islamiques
Authors: Guessous Nouzha
Published: May 2023

La dissociation de la sexualité et de la reproduction, et la technicité et l’extériorisation croissantes de ces dernières par la médecine reproductive contemporaine, perturbent la procréation, la filiation et la parentalité. Cela soulève des questions éthiques, sociales et juridiques que les individus et les sociétés abordent en fonction de leur contexte social et culturel. En outre, ces nouvelles possibilités bouleversent les normes patriarcales qui sous-tendent les relations de genre, et remettent la sexualité et le corps des femmes au cœur du problème. Pourtant, les croyances culturelles et religieuses peuvent empêcher l’accès à certaines possibilités de procréation assistée, tandis que certaines de leurs utilisations peuvent conduire à de nouvelles formes de coercition et de discrimination contre les femmes. Qu’en est-il de la situation dans les sociétés musulmanes où les normes sociales juridiques et traditionnelles, essentiellement religieuses, peuvent entrer en conflit avec ces pratiques nouvellement accessibles ? Comment ces nouvelles possibilités de parentalité sont-elles comprises dans les sociétés musulmanes, où l’organisation sociale, la culture et les lois patriarcales restent prédominantes ? Quelles répercussions peuvent-elles avoir sur les droits des femmes et des enfants ? Cet article aborde ces questions à partir de perspectives historiques islamiques et à la lumière des besoins exprimés aujourd’hui par les musulmans à la recherche d’alternatives respectueuses des droits humains.
Corps et sexualité des femmes au Maroc entre les lois, la culture et les pratiques sociales
Authors: Tauil Leila
Published: May 2023

Depuis des décennies, les féministes marocaines historiques réclament l’égalité des sexes à tous les niveaux de la société en dénonçant systématiquement le Code de la famille et le Code pénal qui les privent d’une égalité pleine et entière dans les sphères privées et publiques. Jusqu’au « printemps arabe », les questions liées au corps des femmes et à la sexualité étaient encore des sujets tabous, bien que ces questions soient au cœur du Maroc et de la majorité des sociétés musulmanes où « l’honneur des hommes dépend des corps des femmes ». Depuis les soulèvements au Maroc et dans le monde arabe, de jeunes féministes subversives n’hésitent plus à aborder publiquement la question du corps et de la sexualité en défendant le droit des femmes à disposer librement de leur corps. Le manifeste historique du collectif 490 « Hors-la-loi », publié au Maroc en septembre 2019 – équivalent au « Manifeste des 343 salopes en France » en 1971 – illustre parfaitement cette révolution en cours. Soutenus par un large éventail de la société civile, les auteurs de ce manifeste dénoncent le caractère obsolète des lois répressives pénalisant l’avortement et les relations sexuelles hors mariage qui poussent la société marocaine, divisée entre un projet social conservateur et moderne, à l’hypocrisie sociale et aux pratiques clandestines jugées illégales. Ce moment historique peut-il révéler les prémisses d’une véritable révolution égalitaire et démocratique au Maroc ?

Le Grand-Est a été fortement touché lors de la première vague de l’épidémie de Covid-19. Dans les suites de la phase aiguë de la maladie sont apparus chez 5 à 10 % patients des symptômes persistants ou résurgents à type de fatigabilité intense, de maux de tête, de gêne respiratoire, de désadaptation à l’effort, perte d’odorat, douleurs musculosquelettiques, dénutrition, etc. La souffrance peut également s’exprimer sous forme d’angoisse, d’insomnie, d’états dépressifs voire d’un syndrome de stress post-traumatique. Dès mars 2020, la Fédération thermale du Grand-Est appelle à innover et à se réinventer pour répondre aux nouveaux besoins de santé face à la situation pandémique inédite. Le projet Covidtherm est initié pour mettre en œuvre dans les établissements thermaux, alors vides de tous curistes, une cure adaptée aux patients porteurs de symptômes persistants de la Covid-19 ; des soins d’accompagnement et de remise en forme des professionnels de santé épuisés physiquement et psychologiquement. La cure thermale offre le temps de repos essentiel pendant la phase de convalescence, permet la réappropriation des rythmes chronobiologiques dont le sommeil qui est le pilier de la récupération, la reprise d’une activité physique adaptée, la resocialisation. Elle constitue une unité de temps et de lieu propice à l’apprentissage de l’auto-gestion de la maladie. L’objectif de la cure thermale post-Covid-19 est de permettre aux patients de retrouver une autonomie, un équilibre psychologique, des capacités physiques, une vie sociale et professionnelle proche de celle de leur vie antérieure, de prévenir les séquelles au long cours par une action globale. La population cible correspond aux personnes souffrant de la persistance ou la résurgence des symptômes apparus de novo dans les suites de l’infection à Sars-Cov2 et persistants après 12 semaines. Le chemin thérapeutique repose sur un certain nombre d’invariants : (1) prescription de la cure Covidtherm par le médecin traitant, hospitalier ou spécialiste, avec transmission des éléments nécessaires à la continuité de la prise en charge ; (2) évaluation des besoins en soins par le médecin thermal, le kinésithérapeute, le psychologue et le diététicien prenant en compte les aspects sociaux et professionnels ; (3) mise en œuvre des soins de crénothérapie associés à des soins spécifiques adaptés aux symptômes. Les auteurs présentent le protocole d’évaluation du traitement thermal. Ce projet est une proposition thérapeutique innovante qui vise à mettre en place un parcours de soin adapté et répondre aux attentes des personnes atteintes de symptômes persistants au décours de la Covid-19 en situation d’errance médicale.

La psammothérapie, également appelée psammatothérapie sablothérapie ou arénothérapie, est une thérapie thermale externe qui utilise la chaleur sèche lors de bains de sable. C’est une médecine traditionnelle pratiquée dans différentes régions du monde, notamment en Italie, au Portugal, en Afrique du Nord, en Asie et au Brésil. Elle peut être réalisée dans un environnement marin ou dans des centres dédiés pour les régions non côtières. Elle représente une ressource thérapeutique complémentaire pour les maladies chroniques rhumatismales et respiratoires, comme la broncho-pneumopathie chronique obstructive. Les mécanismes d’action rapportés sont liés à l’effet thermique, la composition physicochimique du sable utilisé et l’action du climat marin.
Service public français entre digitalisation, externalisation et invisibilisation

Published: May 2023

L’État social, qui est entré depuis les années 1980 dans une logique marchande, soumet aujourd’hui le service public à un nouveau défi : celui du capitalisme de plateforme. Le périmètre de l’action humaine des services publics ne cesse de se réduire au profit de l’augmentation des entreprises privées digitalisées (start-ups), ce qui a pour conséquence l’invisibilité de l’usager. Comment cette transformation réinterroge-t-elle la place des services publics traditionnels, mais également la place de la solidarité dans des politiques publiques digitalisées ? Que devient l’activité du service public lorsque l’usager n’est plus visible ?

Insects have been a component of the human diet for ages, but their popularity as human food has only expanded considerably in recent years due to their potential as a large future food supply with high nutritional content and considerable environmental benefits. One of the promising insects with potential in foodstuff application is the red palm weevil (RPW),Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae). It is believed that with the advancement of new knowledge and technology, edible insects, specifically RPW larvae, would gain more acceptance globally, expand their market, and serve as a more sustainable alternative to meat. The aim of this article is to provide an overview of RPW larvae as human food. This study further emphasises that RPW larvae are suitable for human consumption since they are nutritious. The trade-in edible insects, particularly RPW, presents tremendous potential, as many nations have begun to recognise them as human foods, and other nations, such as Thailand, even produce them on a food business scale. In order to present a more comprehensive perspective, the possibility of the RPW’s mass rearing is also examined. In addition, the global acceptance of RPW cannot be separated from several advantages compared to similar insect larvae of other species in terms of mass-rearing and distribution, as well as nutritional value, which indicates the larvae’s high potential for processing into food products. It is envisaged that this study would give an overview for policymakers to plan and implement more appropriate policies and regulations to assist the growth of the RPW industry.

Edible caterpillars are the most traded edible insects in Cameroon, particularly in the humid forest zone, where they are excellent sources of proteins and fats for many indigenous peoples. Their large consumption and their wild harvest have been a major concern, and there is a need for sustainable management. However, specific data on species’ diversity and trade are scarce. Hence, the present study aims to provide an overview of the socio-economic exploitation of edible caterpillars in the bimodal rainforest zone of Cameroon. Semi-structured interviews were conducted with caterpillar traders in six localities covering the three administrative Regions (East, Centre, and South) of the bimodal forest zone of Cameroon. The socio-demographic characteristics of traders, the traded species, quantities, and prices were recorded. Fresh and live samples were also recorded for morphological identification. A total of 129 traders were interviewed, with the majority being women (94.8%). Eleven species of caterpillars were involved in this trade, with the most remarkable diversity observed in the Centre Region. The traded quantity per species varied significantly with Regions, with the overall most exploited species beingImbrasia oyemensis (13,250.44 kg/year),Imbrasia truncata (4,992.30 kg/year) andAnaphe venata (2,589.51 kg/year). The price of caterpillars differed significantly depending on whether the locality was rural or semi-urban.Notodontidae sp. was the most valuable species (US$ 3.63/kg), followed by species of the genus Anaphe (US$ 3.1±0.5/kg). Special attention should be given to the most traded species to enhance their sustainable exploitation. Further studies on the bio-ecology, habitat and life cycle of these caterpillars are needed for the sustainable management of these beneficial insects. Forest authorities should enhance the regulations governing their exploitation and logging of their host trees.

Enhancement of black soldier fly (BSF) larval body weight with nutraceutical metabolites is a crucial step in utilising BSF larvae as food and feed. As BSF larvae are found in natural habitats comprising decaying organic matter and thriving with yeast species, we hypothesis that metabolic interactions between BSF larvae and the yeast present in their gut will have the greatest influence on the nutritional composition and life cycle of the BSF larvae. In the present study, we compared BSF larvae that were fed withSaccharomyces cerevisiae (Sc), a yeast species used for rearing BSF andCandida spp. (Cs), yeast-like fungi that are common in the BSF larval gut environment. The effect of the yeasts on 5th instar larval body weight was tested, and alteration of metabolic regulation and its impact on related pathways was analysed using liquid chromatography-mass spectrometry (LC-MS) and MetaboAnalyst 5.0 version. The Cs feeding treatment significantly increased larval body weight compared to the Sc treatment. The metabolic pathway analysis demonstrated that the significantly over-accumulated metabolites in the Cs treatment (compared to the Sc treatment) were tyrosine, purine, histidine and vitamin B6 metabolism, while the significantly down-accumulated metabolites in Cs (compared to the Sc treatment) were arginine biosynthesis, phenylalanine, tyrosine and tryptophan biosynthesis, and valine, leucine and isoleucine biosynthesis. In addition, metabolites related to phenylalanine metabolism, D-glutamine and D-glutamate metabolism, and alanine, aspartate, and glutamate metabolism were down-accumulated. However, further study is required on both the BSF and yeast gene expression related to these metabolic pathways in order to better understand yeast-insect metabolite interactions. The overall conclusion of this study is that a supply of yeasts that are adapted to the BSF digestive system contributes to altered metabolic pathways in the BSF larvae and enhances larval body weight, as well as improving nutrient status.

Published: May 2023

In this paper, we studied the estimation of a stress-strength reliability model ($R = P(X>Y)$) based on inverted exponentiated Rayleigh distribution under the unified progressive hybrid censoring scheme (unified PHCS). The maximum likelihood estimates of the unknown parameters were obtained using the stochastic expectation-maximization algorithm (stochastic EMA). The asymptotic confidence intervals were also created. Under squared error and Linex and generalized entropy loss functions, the Gibbs sampler together with Metropolis-Hastings algorithm was provided to compute the Bayes estimates and the credible intervals. Extensive simulations were performed to see the effectiveness of the proposed estimation methods. Also, parallel to the development of reliability studies, it is necessary to study its application in different sciences such as engineering. Therefore, droplet splashing data under two nozzle pressures were proposed to exemplify the theoretical outcomes.

Published: May 2023

In this paper, we describe an experience to test the predominant presence of Delaunay triangulations in the artwork of Okuda, a quite famous, young, contemporary Spanish artist. We addressed this task involving, as a citizen science activity in a STEAM (Science, Technology, Engineering, Art, Mathematics) education context, several hundreds of students (of different kinds: secondary education, university undergraduates, in particular, following teacher training degrees). Each student was asked to select an Okuda archive and, with the concourse of a dynamic geometry program provided with some computational geometry commands, to measure the ratio of coincident triangles in Delaunay's and artist's triangulations, over an ample region of the chosen artwork. The results show a very large percentage of coincidence ratios. We conclude with some reflections about how to interpret this fact, and about the potential role of future, enhanced, dynamic geometry systems to automatically address similar issues, concerning mathematical properties of figures from the real world.

Published: May 2023

In this paper, under some conditions in the Banach space $ C ([0, \beta], \mathbb{R}) $, we establish the existence and uniqueness of the solution for the nonlinear integral equations involving the Riemann-Liouville fractional operator (RLFO). To establish the requirements for the existence and uniqueness of solutions, we apply the Leray-Schauder alternative and Banach's fixed point theorem. We analyze Hyers-Ulam-Rassias (H-U-R) and Hyers-Ulam (H-U) stability for the considered integral equations involving the RLFO in the space $ C([0, \beta], \mathbb{R}) $. Also, we propose an effective and efficient computational method based on Laguerre polynomials to get the approximate numerical solutions of integral equations involving the RLFO. Five examples are given to interpret the method.

Published: May 2023

This paper presents a novel family of bivariate continuous Lomax generators known as the BFGMLG family, which is constructed using univariate Lomax generator (LG) families and the Farlie Gumbel Morgenstern (FGM) copula. We have derived several structural statistical properties of our proposed bivariate family, such as marginals, conditional distribution, conditional expectation, product moments, moment generating function, correlation, reliability function, and hazard rate function. The paper also introduces four special submodels of the new family based on the Weibull, exponential, Pareto, and log-logistic baseline distributions. The study establishes metrics for local dependency and examines the significant characteristics of the proposed bivariate model. To provide greater flexibility, a multivariate version of the continuous FGMLG family are suggested. Bayesian and maximum likelihood methods are employed to estimate the model parameters, and a Monte Carlo simulation evaluates the performance of the proposed bivariate family. Finally, the practical application of the proposed bivariate family is demonstrated through the analysis of four data sets.
