Published: March 2023

To date, the number of scientific studies devoted to the study of speech genres in Uzbekistan is increasing. This is important in determining the specific features of speech genres in the Uzbek language system. Speech genres characteristic of colloquial speech, often used in everyday life, expressing the features, topics, interests, and traditions of people's daily speech occupy a certain place in the language system. Modern forms of speech genres that have been practiced since human society until now reflect centuries-old historical views. Therefore, the study of the modern form of each speech genre and the history of its origin makes it possible to compare the historical and modern forms of these speech genres

Published: March 2023

The presented study comprises the one-pot synthesis and the characterization of quercetin- and caffeic acid-functionalized chitosan-capped colloidal silver nanoparticles (Ch/Q- and Ch/CA-Ag NPs), and their antibacterial and anticancer activities. The formation of Ch/Q- and Ch/CA-Ag NPs has been confirmed by ultraviolet–visible (UV–vis) spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM). The characteristic surface plasmon resonance (SPR) absorption band has been found at 417 and 424 nm for Ch/Q- and Ch/CA-Ag NPs, respectively. The formation of a chitosan shell comprising quercetin and caffeic acid, which surround the colloidal core Ag NPs, was confirmed by UV–vis, and FTIR analyses, and monitored by TEM microscopy. The size of nanoparticles has been determined as 11.2 and 10.3 nm for Ch/Q- and Ch/CA-Ag, respectively. The anticancer activity of Ch/Q- and Ch/CA-Ag NPs has been evaluated against U-118 MG (human glioblastoma) and ARPE-19 (human retinal pigment epithelium) cells. Both NPs showed anticancer activity, but Ch/Q-Ag NPs seemed to be more effective on cancer cell lines (U-118 MG) in comparison to healthy ones (ARPE-19). Furthermore, the antibacterial activity of Ch/Q- and Ch/CA-Ag NPs against Gram-negative (P. aeruginosa and E. coli) and Gram-positive (S. aureus and S. epidermidis) bacteria was determined, and dose-dependent antibacterial effects were found.

Published: March 2023

Se preparó un nanocompósito por medio del método de polímerización in situ. Las materias primas para la elaboración de este nanocompósito fueron un hule de silicona cargado con diatomeas y óxido de grafeno reducido, ambos de grado industrial. Mediante microscopia electrónica de barrido (SEM) se analizó la morfología de la superficie del compósito observándose conjuntos de láminas de óxido de grafeno reducido (OGR) en la superficie del hule de silicona (HS). Con el propósito de estudiar la dispersión del OGR se realizaron estudios mediante microscopía electrónica de alta resolución (STEM) y microscopía óptica por luz transmitida, estos métodos fueron útiles para poder discriminar las áreas donde existe HS, pero no para poder distinguir entre las áreas donde existe OGR y diatomeas. Los resultados obtenidos por STEM son útiles para el estudio de fenómenos a nivel micro y nano escala en sistemas de nanocompósitos. El análisis realizado por microscopia óptica por luz transmitida puede ser útil para poder explicar fenómenos de formación de caminos de conductividad térmica. Este compósito tiene aplicaciones potenciales para ser usado como disipador de calor en la industria de la arquitectura y electrónica. Los materiales usados son de grado industrial y esto disminuye el tiempo requerido para realizar pruebas previas para aplicaciones industriales.

Authors: Siddiq Abu Bakker , Sharif Sherajul Mustajib
Published: March 2023

COVID-19 is a devastating global crisis leading to unprecedented challenges in public health, food systems, the workforce, etc. The calamity has aggravated the situation for informal workers by putting them at risk of economic fallout. The informal workers remain exceptionally vulnerable as their livelihood depends on in-person daily labor. As the pandemic unfolds worldwide, informal workers face tremendous socio-economic challenges and health-related vulnerabilities. This research sheds light on this terrain to explore the impact of COVID-19 on informal workers in Bangladesh from a socio-economic perspective. At the same time, it also analyzes the legal aspects from a critical point of view. It employs a qualitative research methodology. Primary data were collected through 30 in-depth interviews with informal laborers such as taxi-driver, street vendors, domestic workers, hotel and restaurant stewards, and private tuition providers. Ten key informant interviews were conducted with trade union leaders, relevant practitioners, and researchers. It finds that informal workers face diverse challenges, such as the inability to manage family expenditure, drop-out of their children from education, lack of information on health protection, internal migration, etc. It also reveals a significant policy implementation gap in crisis management by analyzing fiscal and monetary policy, non-therapeutic measures, and social safety programs.

Characterizing the bulk compositions of transiting exoplanets within the M dwarf radius valley offers a unique means to establish whether the radius valley emerges from an atmospheric mass-loss process or is imprinted by planet formation itself.

). TOI-1695 b’s radius and orbital period situate the planet between model predictions from thermally driven mass loss versus gas depleted formation, offering an important test case for radius valley emergence models around early-M dwarfs. We confirm the planetary nature of TOI-1695 b based on five sectors of TESS data and a suite of follow-up observations including 49 precise radial velocity measurements taken with the HARPS-N spectrograph. We measure a planetary mass of 6.36 ± 1.00 M
⊕, which reveals that TOI-1695 b is inconsistent with a purely terrestrial composition of iron and magnesium silicate, and instead is likely a water-rich planet. Our finding that TOI-1695 b is not terrestrial is inconsistent with the planetary system being sculpted by thermally driven mass loss. We present a statistical analysis of seven well-characterized planets within the M dwarf radius valley demonstrating that a thermally driven mass-loss scenario is unlikely to explain this population.

Interstellar neutral atoms enter the heliosphere at a relatively slow speed corresponding to the motion of the Sun through the local interstellar medium, which is approximately 25 km s−1. Neutral hydrogen atoms enter from the approximate location of the Voyager spacecraft and are eventually ionized primarily by collision with thermal solar wind ions. An earlier analysis by Hollick et al. examined low-frequency magnetic waves observed by the Voyager spacecraft from launch through 1990 that are thought to arise from the scattering of newborn interstellar pickup H+ and He+. We report an analysis of Voyager 1 observations in 1991, which is the last year of high-resolution magnetic field data that are publicly available, and find 70 examples of low-frequency waves with the characteristics that suggest excitation by pickup H+ and 10 examples of waves consistent with excitation by pickup He+. We find a particularly dense cluster of observations at the tail end of what is thought to be a Merged Interaction Region (MIR) that was previously studied by Burlaga & Ness using Voyager 2 observations. This is not unexpected if the MIR is followed by a large rarefaction region, as they tend to be regions of reduced turbulence levels that permit the growth of the waves over the long time periods that are generally required of this instability.
The Messy Nature of Fiber Spectra: Star–Quasar Pairs Masquerading as Dual Type 1 AGNs

Published: March 2023

Theoretical studies predict that the most significant growth of supermassive black holes (SMBHs) occurs in late-stage mergers, coinciding with the manifestation of dual active galactic nuclei (AGNs), and both major and minor mergers are expected to be important for dual AGN growth. In fact, dual AGNs in minor mergers should be signposts for efficient minor-merger-induced SMBH growth for both the more and less massive progenitor. We identified two candidate dual AGNs residing in apparent minor mergers with mass ratios of ∼1:7 and ∼1:30. Sloan Digital Sky Survey (SDSS) fiber spectra show broad and narrow emission lines in the primary nuclei of each merger while only a narrow [O iii] emission line and a broad and prominent Hα/[N ii] complex is observed in the secondary nuclei. The FWHMs of the broad Hα lines in the primary and secondary nuclei are inconsistent in each merger, suggesting that each nucleus in each merger hosts a Type 1 AGN. However, spatially resolved Large Binocular Telescope optical spectroscopy reveals rest-frame stellar absorption features, indicating the secondary sources are foreground stars and that the previously detected broad lines are likely the result of fiber spillover effects induced by the atmospheric seeing at the time of the SDSS observations. This study demonstrates for the first time that optical spectroscopic searches for Type 1/Type 1 pairs similarly suffer from fiber spillover effects as has been observed previously for Seyfert 2 dual AGN candidates. The presence of foreground stars may not have been clear if an instrument with more limited wavelength range or limited sensitivity had been used.

Enteric viruses are major causes of waterborne diseases and are present in large quantities in the stools of infected individuals. Its viability in the environment lasts for months, favoring the contamination of water used for consumption and recreation. The study aimed to monitor monthly the circulation of enterovirus (EV) and group A rotavirus (RVA) in recreational freshwater from an island region used as a bathhouse in northern Brazil, from January 2012 to December 2013. The viral RNA was obtained using guanidine isothiocyanate/silica after viral concentration by adsorption-elution method. The molecular detection was carried out by semi (EV) and nested-PCR (RVA) and the amplicons were sequenced on automated sequencer. At least one of these viruses was detected on 40.4% (42/104) of the samples. RVA was the most frequent (n = 32; 30.8%) when compared to EV (n = 20; 19.2%). Co-circulation between both was identified in 9.6% (n = 10). The highest viral positivity was found in SP02 (46.1%). The highest viral positivity was observed during high tides (57.7%; 60/104). Most EV samples were characterized as coxsackievirus (CV) A5 (85.7%, 12/14) and others as Sabin 1 poliovirus (14.2%, 2/14). The RVA positive samples were genotyped as G2, G3, G9, G12, P[8], P[4], and P[6]. These viruses were detected in 35.6% (37/104) of the samples with an acceptable concentration of fecal coliform bacteria. These results demonstrate the contamination of surface water intended for recreation by enteric viruses of Public Health concern even when bacterial indicators are within the tolerated limit, a factor that confirms the need for public policies aimed the sewage treatment before its release into water bodies.

Microplastics are an increasing threat to marine fauna and oceanic habitats, potentially affecting sea turtle nesting beaches. Hawksbill sea turtles (Eretmochelys imbricata) are a Critically Endangered species with decreasing population trends. There are several hawksbill rookeries in the southern Caribbean Sea, particularly on Los Garzos Beach, the main nesting site of continental Venezuela. A preliminary physical analysis of microplastics sampled from 10 sites on Los Garzos Beach reported high numbers (94 ± 2.5 items) of 14 different materials and colors. Microplastic counts at 10 sites averaged 1504 ± 405.61 items m-2, higher than other sea turtle nesting sites worldwide. There were no statistical differences in the concentration of microplastics at the sampled sites of Los Garzos Beach. However, the concentration of microplastics on this beach is higher at the midpoint of the falling tide (3520 ± 405.61 items m-2) and the top of the sea turtle nesting area (3840 ± 405.61 items m-2). We speculate that this debris could harm the nesting environment of hawksbill sea turtles in the region. While this study presents preliminary values for microplastics in an important hawksbill turtle nesting beach in Venezuela, it also serves as a baseline for long-term studies that can help determine the impact and sources of plastic pollution in sea turtle rookeries.

The biodiversity of epibenthic communities in rocky reefs in the Mexican tropical Pacific has been studied minimally during the past three decades. This study describes the abundance and distribution of algae and invertebrates in a deep rocky reef from this region. Samples were taken at 20 m depth in 2012 by randomly placing 50×50 cm quadrats. Also, photographs were taken of each quadrat to quantify the coverage of organisms. Throughout the study, the algae were the most abundant group (17748.5 cm m-2), of which encrusting calcified (6350.9 cm m-2), turf (3040.3 cm m-2), and larger-sized articulated corallines (2700.9 cm m-2) had the highest coverage. Regarding invertebrates, zoanthids (1153.3 cm m-2) and corals (746.7 cm m-2) had high coverage. All of the algal groups were found on vertical and horizontal substrates. The detrended correspondence analysis showed that larger-sized articulated corallines and encrusting not calcified groups were prevalent on the horizontal substrate and corals on the vertical substrate. These abundance and distribution patterns represent the first quantitative study of rocky reefs from the region. Considering the rapid influence of human activities in this coastal zone and the fact that rocky reefs have been minimally studied, there is a clear need for long-term monitoring programs to establish reef communities' patterns and processes, which are useful in conservation programs.

Published: March 2023

Hoya medusa M.D.De Leon, Cabactulan, Cuerdo & Rodda, sp. nov. (Apocynaceae, Asclepiadoideae) is described from the Philippines. Even though numerous taxa with a shrubby habit from this area are known, it can be immediately separated because of its urceolate corolla and prominent elongated corona lobes. No other species in the genus possesses such a combination of characters.

Published: March 2023

Body mass is one of the most influencing factors of metabolic rate and gas exchange of animals, and also related to activity pattern and occupancyof ecological niches. This study aimed to understand the relationships between body mass (MB) and morpho-functional features ofthe lungs of Iguana iguana, through morphological and morphometric characterization of the structural elements of the respiratory system.Iguana iguana has lungs of the transitional type, the heterogeneously distributed parenchyma being faveolar in cranial and medial regionsand trabecular in the caudal region. Within the parenchyma, 43.6 ± 25.5% corresponds to faveoli, 18.0 ± 5.9% to interfaveolar septa, and38.7 ± 31.6% to trabeculae. Within the interfaveolar septa, 9.4 ± 4.0% corresponds to blood capillaries, 4.4 ± 1.0% to type I pneumocytes And 3.9 ± 1.1% to type II pneumocytes. Allometric analyses showed that lung (MB 0.8949) and parenchymal volume (MB 1.030) scale with MB in I. iguana just as in other lizards with unicameral or transitional lungs, which was unexpected for lung volume, since reptilian lung volume is generally considered to scale as MB 0.75. The functional orphology of the lungs in I. iguana seems to play an important role to meet the metabolic demands through ontogenetic growth.
A review of sexual dimorphism of eye size in Colubroidea snakes

Eye size is interesting in snakes because in most species body length differs between the sexes, while the eye’s performance depends on its absolute size. So, does the smaller sex see less well? We hypothesized that eye sexual mensural dimorphism (SMD) would be smaller than Body SMD. We found among 26 snake populations that body length SMD was female biased in 47.6% and male biased in 38.1% of samples. Often the larger sex’s head was further enlarged but the SMD of absolute eye size was mitigated or annulled by the smaller sex’s eye being enlarged within the head, and the head enlarged relative to the body. Overall generally the SMD of eye size was smaller than body SMD. This accords with a hypothesis that eye size affects the evolution of head size and its SMD, both reflecting and emphasizing that absolute eye size is functionally important. Although Colubridae exceed Viperidae in length, Viperidae have larger eyes in absolute terms. In Colubridae the females have larger eyes and in Viperidae the males have larger eyes. Additionally we examine to what extent SMD in different characters is correlated, and briefly review other aspects of SMD, including some aspects of Rensch’s rule.

The record of a new species ofEchinolaophonteNicholls, 1941 (Copepoda, Harpacticoida, Laophontidae) from Jeju Island (Korea) formed the basis for a detailed and exhaustive phylogenetic revision of the genus. Comparison of all 15 species currently assigned toEchinolaophonte(including the new Korean species) revealed that its current composition cannot be maintained. The phylogenetic relationships withinEchinolaophontewere elucidated through the analysis of 135 morphological characters and the inclusion of four outgroups. As a result, four species were removed fromEchinolaophonteand placed in two new genera:Parechinolaophontegen. nov.forE. tropicaUmmerkutty, 1970 andPseudechinolaophontegen. nov.forE. minutaCottarelli & Forniz, 1991,E. mordoganensisKuru, Sönmez & Karaytug, 2019 andE. veniliaeCottarelli, Forniz & Bascherini, 1992.Echinolaophonte longantennataApostolov, 1990 had to be excluded from the analysis, due to the fragmentary and imprecise description. Accordingly, the phylogenetic relationships of the ten species remaining inEchinolaophonteare clarified. The new Korean species is described asEchinolaophonte musasp. nov.Furthermore, the subspecies E. armiger f. briani Lang, 1965 is elevated to species rank asE. brianiLang, 1965. A detailed phylogenetic discussion is provided and a key to the species ofEchinolaophonteis given.
Dans l’interstice du silence de la méditation : la spiritualité ?
Authors: Nizard Caroline
Published: March 2023

À la lumière de terrains ethnographiques au sein d’une retraite silencieuse Vipassana et d’une formation MBSR, mindfulness based stress reduction , cet article s’intéresse au processus de transformation, à la performativité des perceptions corporelles, des pratiques qui amènent à la construction du sujet comme méditant, en mettant l’accent sur le silence, parfois interprété comme une expression de la spiritualité. Si la MBSR se définit comme « laïque » alors que le courant Vipassana se présente comme issu du bouddhisme Théravada, comment les pratiquants peuvent-ils être amenés à rencontrer les mêmes expériences ?

L’écospiritualité : se relier aux êtres de la Terre
Authors: Chamel Jean
Published: March 2023

À partir de l’ethnographie des réseaux enchevêtrés de la collapsologie de l’écopsychologie, cet article montre comment l’écospiritualité, vécue au travers de pratiques de mise en relation directe avec le cosmos et les êtres qui le peuplent, repose sur la vision moniste d’une « immanence transcendantale ». Cette spiritualité écologique répond au besoin de donner du sens à un monde qui n’en a plus guère pour ces écologistes, en mettant l’accent sur un idéal d’harmonie à (re)composer avec les « autres qu’humains ». L’écospiritualité n’implique donc pas nécessairement une relation au divin – ce qui est le sens original de la notion de spiritualité – mais celle-ci reste possible et est mobilisée par les acteurs se réclamant d’une écospiritualité chrétienne de type panenthéiste, non sans risquer d’être réduits à des « adorateurs de Gaïa ».
Lecteurs et glaneurs sur le Bon Coin : deux formes de travail amateur dans le commerce du livre d’occasion
Authors: Chabault Vincent
Published: March 2023

Bénéficiant d’une visibilité médiatique certaine, les reventes de biens durables sur le marché de l’occasion s’expliquent avant tout par des facteurs économiques dans un contexte de crise et d’accroissement des inégalités. Par ailleurs, l’appropriation des technologies numériques, mais aussi de nouvelles valeurs de consommation en faveur du réemploi et de la lutte contre le gaspillage, encouragent chacun à donner une seconde vie aux produits achetés. En analysant les étapes de re-commercialisation de livres sur le Bon Coin, cet article met en lumière les savoir-faire mobilisés par les particuliers et le sens donné à cette activité. Cet engagement leur procure des revenus ainsi que des rétributions d’ordre symbolique permettant d’expliquer l’investissement de ces néo-libraires sur un temps dédié au loisir.
