Published: June 2024

Abstract
The topography plays a significant role in determining the rate of soil loss. The Digital Elevation Model (DEM) retrieved from earth observation products can be used to calculate the slope length and steepness, which are important factors in the Revised Universal Soil Loss Equation (RUSLE) used to estimate soil erosion. In the present study, the effect of two DEM resolutions (30m and 90 m) on RUSLE model results was assessed and used to quantify the rate of soil loss in Settat province (Morocco), specifically in certain abandoned quarries. As a result, DEM-30 and DEM-90 soil erosion rates vary from 0 to 282.77 t.ha-1.yr-1 and 0 to 13.79 t.ha-1.yr-1, respectively. At the quarry level, the abandoned quarries showed soil loss rates ranging from 0 to 7.92 t.ha-1.yr-1 for DEM-30. Contrary to this, the soil loss rate for DEM-90 data was zero. To summarize, for more relevant and detailed conclusions, high-resolution data must be used to collect more information and describe the erosion process with as much detail as possible, especially for small areas.

Authors: Moni Mout Joya , Sarmah Ranjan Kumar 
Published: June 2024

AbstractThe Eocene Kopili Sandstone outcropping in the North Cachar Hills (NCHs) of Assam, India, was petrographically studied to unravel its diagenetic features, provenance, tectonic setting and palaeoclimate conditions. The modal analysis of the Kopili Sandstone reveals that the detrital mineralogy is dominated by quartz (48.78 to 83.70 %), with variable amounts of rock fragments (0.37 to 7.35 %), feldspar (0.37 to 8.33 %), micas (0.36 to 7.84 %) and subordinate amount of heavy minerals. The matrix and cement content varies from 9.88 to 21.50 % and 1.12 to 19.41 % respectively. The Kopili Sandstone is classified as quartz arenite to sub lithic arenite. Compaction, cementation, dissolution and replacement are the observed diagenetic processes in the studied sandstones. Diagenetic transformations are manifested in the fractured detrital grains, overgrowth of quartz, corrosion of grain boundaries of quartz, modification of grain boundaries, and silica and iron oxide cement precipitation in the interstices of the framework grains. The provenance is of granite-gneissic rock terrain. The detritus in the depositional basin is derived predominantly from craton interior with minor input from recycled orogen. The study discerns humid palaeoclimate conditions for the Kopili Sandstone.

Published: June 2024

Abstract
Pulmoddai mineral sand deposit which extends about 800,000m2 is located in the Northeast coastal zone of Sri Lanka. It is the largest and well known heavy mineral sand deposit in Sri Lanka. High-quality Zirconium-bearing minerals like Rutile, Zircon, and Ilmenite are concentrated in this deposit. This study focuses to analyse the spatial distribution of the heavy minerals abundance and sedimentlogical characteristics of the deposit. Five miles (8 km) long stretch along the coast of this deposit was selected as the study area. Ten traverses representing two traverses within each mile are demarcated across the coastline and are running from inshore to backshore. Forty sand samples representing inshore, swash zone, berm, and backshore region were collected. These samples were analysed using a dry sieve and heavy liquid separation methods. According to statistical analysis, sediments in the Pulmoddai mineral sand deposit are mostly fine-grained, moderately to moderately well sorted. Also, these are negatively skewed to nearly symmetrical and mesokurtic in nature. According to the linear discrimination function, these sediments are shallow marine agitated depositions controlled by aeolian, fluvial and marine depositional environments under the high impact of turbidity currents. The average heavy mineral concentration at the inshore, swash zone, berm region, and backshore (dune) region is 5.95%, 10.87%, 12.82%, and 23.5% respectively. The concentration of the heavy minerals increases towards the backshore and also increases towards the southern part of the study area.

Published: June 2024

ABSTRACTThe Paleogene sediments of the Shillong Plateau are exposed in the southern part of Meghalaya and are designated as the Jaintia Group. The Lower Sylhet Sandstone Member (LSSM) (Therria Sandstone) is the lowermost member of the Shella Formation of Jaintia Group. To understand the depositional history of the studied sandstones, petrographic and geochemical approaches have been made. Petrographically, these sandstones are classified as quartz arenite and quartz wacke. They were derived from intermediate to upper rank metamorphic and plutonic source which were deposited in a craton interior and quartzose recycled tectonic setting. The paleoweathering indices of CIA, CIW, PIA and ICV indicate that the weathering at the provenance was intense. The tectonic discrimination diagrams suggest passive margin setting for their sedimentation and climatic condition during the deposition was humid in nature. The studied sediments were deposited in non-marine conditions as evidenced by the geochemical proxies and primary sedimentary structures existing in the LSSM.

Published: June 2024

Este ensayo se adentra en el tema de los estereotipos en el liderazgo femenino, analizando cómo estos prejuicios y creencias limitantes afectan la participación y el ascenso de las mujeres en roles de liderazgo. Por esta razón, los estereotipos en el liderazgo femenino son un tema relevante y complejo que se enfrenta a varios desafíos, que pueden ser asociados negativamente a los rasgos atribuidos a la debilidad.
De manera que, se expone a los estereotipos de género como imágenes socialmente compartidas, rígidas y generalizadoras, que describen los rasgos que se afirma poseen las personas de un determinado grupo social. Esto puede resultar en una falta de confianza en las mujeres, en la autoexclusión de los puestos de responsabilidad, dificultando la ascensión de las mujeres a los altos cargos. Asimismo, se plantea la necesidad de un cambio cultural y organizacional que promueva la diversidad y la equidad de género en las empresas.
Finalmente, se considera que para la construcción de sociedades más equitativas e incluyentes es importante desafiar estos estereotipos, demostrar que es esencial cambiar las percepciones de lo que significa ser líder, promover la confianza en las mujeres y derribar el techo de cristal en las organizaciones.

Published: June 2024

Making signals better than noise in communication has always been challenging for scientists. Researchers have been working on it in different ways. The computer-aided geometric design is a new research field emerging from the collaboration of computer algorithms and mathematical logic towards curve designing, in which the subdivision schemes used have a key position due to their flexible and smooth behaviour. Using parameters in these schemes allows for increased control over designing. A parameterized framework for generating a wide range of subdivision surfaces with tunable degrees of shape control is presented in the family of schemes. The properties of the proposed family make it suitable for use in isogeometric analysis, computer animation, and geometric modelling. The purpose of this paper is to construct and analyze a family of 4-point ternary subdivision schemes to smooth the curves based on the Laurant polynomial. This family is generated by tuning the weight parameter. The scheme is analysed for its different properties. The scheme has continuity. Visual performance of the subdivision scheme is also provided as an application of this proposed study.
Mеsozoic Tectonothermal Evolution of the Zagan Metamorphic Core Complex in Western Transbaikalia: 40Ar/39Ar and FTA Dating

Published: June 2024

Abstract
A model of tectonothermal evolution of the Zagan metamorphic core complex (MCC) based on the new data from 40Ar/39Ar dating of amphibole, mica, and apatite fission-track dating is discussed. A relationship with the long-range impact of processes from the collision of the North China (Amurian–North China) block with the Siberian continent in the Mesozoic era is proposed. The Zagan MСС was formed in the Cretaceous period on the southern flank of a high mountain uplift of Western Transbaikalia, composed of late Paleozoic granitoids of the Angara–Vitim batholith. According to 40Ar/39Ar dating of amphiboles and micas from the mylonite zone, the active development time of the Zagan MCC corresponds to the early Cretaceous epoch (131, 114 Ma). The tectonic exposure of the core from about 15 km to the depths of about 10 km occurred at a rate of tectonic erosion of 0.4–0.3 mm/year as a result of post-collisional extension of the Mongol–Okhotsk orogen. Apatite fission-track dating shows that further exhumation and cooling of the rocks to about 3 km occurred in the lower-upper Cretaceous epoch (112, 87 Ma). The erosional denudation rate was about 0.3 mm/year.MCC- metamorphic core complexes, AFT- apatite fission-track
More Biosurfactants and Fewer Synthetic Surfactants to Improve Alkali-Surfactant-Polymer Flooding: Feasibility Study and Large-Scale Field Application
Authors: Dong Yeliang , Liu Dexin , Fan Yu 
Published: June 2024

Summary
Alkali-surfactant-polymer (ASP) flooding has achieved highly enhanced oil recovery (EOR) in the Daqing Oil Field; however, there are concerns about synthetic surfactants owing to their high cost and difficulty in biodegradation. Cheap biosurfactants conform to human concepts of green circular economy; however, known biosurfactants, as well as their mixtures with alkali, cannot reduce water/oil interfacial tension (IFT) to ultralow values below 0.01 mN/m, which is necessary for ASP flooding to effectively mobilize residual oil. Therefore, we investigate the feasibility of partially replacing synthetic surfactants with biosurfactants rather than completely replacing them to improve ASP flooding. First, through a series of IFT tests, a blend of rhamnolipids (RLs) and alkylbenzene sulfonate (ABS) in a 1:1 mass ratio is determined to be the optimal mixed surfactant and labeled RL/ABS-opt. Second, the interfacial activities, phase behaviors, and wettability alteration capabilities of ASP solutions with RL/ABS-opt are studied. Then, 1.0 wt% NaOH and 0.2 wt% RL/ABS-opt are determined to construct a new ASP system. Subsequently, the waterflooded cores are displaced using the new and the classical ASP systems. Based on the promising experimental results, the new ASP system floods a test block of 56 wells for 3 years. The EOR and surfactant costs are calculated to determine the technical and economic effects. Finally, the concentrations of surfactants before and after activated sludge treatment (AST) are tested by spectrophotometry to verify the biodegradability of RLs better than that of ABS. The laboratory and field results indicate that more biosurfactants and fewer synthetic surfactants could improve ASP flooding to be more environmentally friendly and cost-effective with a higher EOR.

Abstract

New research at Tell al-Hiba, ancient Lagash, has revealed evidence of significant flooding and widespread destruction in the Mesopotamian city during the Early Dynastic period. We identify and date a prominent water-formed feature that cut through its primary temple district. Geoarchaeological trenching and geophysical prospection indicate that an upstream river avulsion led to rapid fluvial sedimentation within the settlement. Further analysis of archaeological data, including newly reported radiocarbon dates, suggests that this environmental crisis occurred during or shortly after Lagash was attacked by Lugalzagesi, king of Uruk. This study therefore also contributes to an improved chronometry of 3rd-millennium BC Mesopotamia.

Published: June 2024

Abstract

Background
Genetic mitochondrial diseases are a major challenge in modern medicine, impacting around 1:4,000 individuals. Leigh syndrome is the most common pediatric presentation of mitochondrial disease. There are currently no effective clinical treatments for mitochondrial disease. In humans, patients are often treated with antioxidants, vitamins, and strategies targeting energetics. The vitamin-E related compound vatiquinone (EPI-743, α-tocotrienol quinone) has been the subject of at least 19 clinical trials in the US since 2012, but the effects of vatiquinone on an animal model of mitochondrial disease have not yet been reported. Here, assessed the impact of vatiquinone on disease progression and in two animal models of mitochondrial disease.
Methods
The efficacy of vatiquinone in vitro was assessed using human fibroblasts treated with the general mitochondrial oxidative stress inducer paraquat, the GPX4 inhibitor RSL3, or the glutathione synthase inhibitor BSO in combination with excess iron. The therapeutic potential of vatiquinone in vivo was assessed using tamoxifen-induced mouse model for GPX4 deficiency and the Ndufs4 knockout mouse model of Leigh syndrome. In both models, animals were treated daily with vatiquinone or vehicle and relevant disease endpoints were assessed.
Results
Vatiquinone robustly prevented death in cultured cells induced by RSL3 or BSO/iron, but had no effect on paraquat induced cell death. Vatiquinone had no impact on disease onset, progression, or survival in either the tamoxifen-inducible GPX4 deficient model or the Ndufs4(-/-) mouse model, though the drug may have reduced seizure risk.
Conclusions
Vatiquinone provided no benefit to survival in two mouse models of disease, but may prevent seizures in the Ndufs4(-/-) model. Our findings are consistent with recent press statements regarding clinical trial results and have implications for drug trial design and reporting in patients with rare diseases.

Published: June 2024

Abstract

This work investigated effects of friction stirred processing (FSP) parameters on the wear resistance of 7075 aluminum alloy. The results indicate the significantly higher wear rate and average coefficient of friction during the stabilization stage of samples W1 (welding speed: 60 mm/min; rotation speed: 1000 rpm) and W8 (welding speed: 80 mm/min; rotation speed: 1200 rpm), with increases of 45% and 40% for the wear rate, respectively, and 19% and 13% for coefficient of friction in comparison with the untreated material. The optimized FSP parameters can considerably improve the wear resistance of the material by affecting the heat input, which altered the grain size and distribution in the welded zone. X-Ray diffraction and scanning electron microscopy/energy dispersive spectroscopy studies provided the mechanism underlying grain size and plastic nano twin structures contributions to wear resistance.

Published: June 2024

Abstract

The synthesis of water-soluble nanoparticles is a well-developed field for ferrite-based nanoparticles with the majority consisting of iron oxide or mixed metal iron oxide nanoparticles. However, the synthesis of non-agglomerated non-ferrite metal/metal oxide NPs is not as well established. The synthesis and characterization of uniform 20 nm, biologically compatible cobalt oxide (CoO) nanoparticles (NPs) is described. These nanoparticles have two principle components: 1) a CoO core of suitable size to contain enough cobalt atoms to be visualized by X-ray fluorescence microscopy (XFM) and 2) a robust coating that inhibits NP aggregation as well as renders them water-soluble and biocompatible (i.e. stealth coatings). Stable cobalt oxide NPs are obtained with octadecyl amine coatings as reported by Bhattacharjee. Two strategies for solubilizing these NPs in water were investigated with varying degrees of success. Exchanging the octadecyl amine coating for a nitrodopamine anchored PEG coating yielded the desired water-soluble NPs but in very low yield. Alternately, leaving the octadecyl amine coating on the NP and interdigitating this with a maleic anhydride-vinyl copolymer with different hydrophobic sidechains followed by opening the maleic anhydride ring with amine substituted PEG polymers (the water solubilizing component), yielded the desired water soluble NPS were obtained in good yield. Characterization data for the nanoparticles and the components of the coatings required for bioorthogonal reactions to ligate them with biotargeting agents are also described.

Abstract

Congenital dyserythropoietic anemia (CDA) is a rare heterogeneous hereditary disorder characterized by ineffective erythropoiesis and morphological abnormalities of erythrocytes and bone marrow erythroblasts. Currently, six types of CDA with different genetic mutations have been identified, with CDAII being the most prevalent. CDA II is an autosomal recessive disorder with the causative gene on the SEC23B gene at 20q11.2. To date, 110 mutations in the SEC23B gene have been reported in CDA II. This paper reports a case of congenital dyserythropoietic anemia type II caused by a new SEC23B mutation and accompanied by a large segmental deletion at the SEC23B gene locus. In addition, we reviewed the diagnostic and therapeutic advances in CADII

Method
A total of 313 student athletes, 133 females and 180 males, enrolled in the sports sciences faculties undergraduate programs of three different state universities, participated in the research in which the relational screening model was adopted. The data was obtained by using the "Personal Information Form", "Social Media Addiction Scale", "Fear of Missing Out in Social Environments Scale" and "Body Appreciation Scale". Data were analyzed by using Pearson correlation and Regression analyses.
Findings: The results obtained in the study showed a negative relationship between social media addiction and body image (p < .05); There is a positive relationship between social media addiction and fear of missing out (p < .05); It was determined that there were negative (p < .05) significant relationships between fear of missing out and body image perception. Moreover, it has been revealed that social media addiction negatively predicted body image (p < .05); fear of missing out positively predicted social media addiction (p < .05); the fear of missing out predicted body image negatively (p < .05).
Conclusion
As a result, it may be possible to state that addiction to social media in student athletes negatively affects their body image, and having the fear of missing out leads to social media addiction and lowers their body image.
