Deformation and recrystallization of sulfide interlayers at the Golets Vysochaishii Gold-Ore Black-Shale Deposit
Authors: Onishchenko S. A.
Published: January 2024

Research subject. The relationship of sulfide interlayers in silt-pelitic rocks with the cleavage of the axial surface at the Golets Vysochaishii gold-ore black-shale deposit (Bodaibo ore district). Methods. The structure of rocks was studied in out-crops, borehole cores, sanded samples, transparent and polished sections. The chemical composition of minerals was determined. Results. It was established that sulfide and sulfide-containing interlayers undergo deformation and recrystallization together with the host silt-pelitic rocks during plastic dynamometamorphic transformations of rocks. Conclusions. Metamorphic transformations of rocks took place in two stages. During the folding-thrust deformations of the first stage, a cleavage of rocks is formed, which leads to the splintering of sulfide interlayers with the orientation of the lenses along the cleavage. Metamorphic transformations of the second stage are manifested in sulfide and sulfide-containing interlayers in the collective recrystallization of their composing minerals with the replacement of surrounding rocks deformed at the previous stage. The second stage is characterized by changes in the mineral composition of rocks, manifested in the substitution of pyrrhotite with pyrite, increase in the iron content of chlorites and carbonates.

Research subject. Spatial distribution of bioavailable strontium in the South Trans-Urals. Aim. Development and test of a methodology for obtaining a bioavailable strontium map suitable for studying migrations and mobility in the Bronze Age in the Southern Trans-Urals. Methods. Sampling was conducted in 73 loci located in a uniform network in a 25 ± 5 km grid and in 22 additional loci (transects along the intermediate lines in places of complex geological structure). The determination of strontium content was carried out by the ICP-MS method. The strontium isotope composition was measured using an inductively coupled plasma magneto-sector multi-collector mass spectrometer (MC-ICP-MS). Statistical methods included analysis with stem-and-leaf plots; Student’s t-test; ordinary kriging (the mean is unknown) with linear semivariogram; analysis of correlation according to Pearson’s test. Results. The surveyed area is 36 sq. km2. The sample size is 357. Samples for different types have similar mean and median values; the differences occur in the fourth fractional digit. Criterion 1 (n ≥ 0.001) can be used to determine local variability, and Criterion 2 (0.706 < n < 0.716) can be used to assess the origin of ancient individuals, animals, and archaeological objects. The interpolated maps for each sample type were created. All bioavailable strontium maps show similar spatial patterns. Cross-validation revealed areas of the lowest accuracy. Conclusions. The similarity of the distribution of anomalies on the maps of different types suggests the feasibility of the sampling technique. There is a clear tendency for the zones of elevated 87Sr/86Sr values to be associated with the older lithology (0.7106, mean). The lower values (0.7091 ± 0.002) are associated with the younger lithology. Given the complex geological structure and a wide range of rocks in the study area, a positive result is the low differentiation of the zoning of the identified anomalies, which correspond to large structural-formation zones of the Urals. The presented method demonstrates its suitability for studying sublatitudinal migrations of the ancient population of the Southern Trans-Urals.

Published: January 2024

El presente trabajo tuvo como objetivo realizar una revisión sistemática del uso de imágenes Sentinel-2 para el monitoreo de la cobertura boscosa a nivel global, para lo cual se empleó el protocolo propuesto por Prisma 2009. La búsqueda de los artículos científicos publicados entre el 2015 y 2021 se realizó en las bases de datos: Scopus y Science Direct, analizándose un total de 65 artículos en los que se detalla los diferentes tipos de clasificadores utilizados para procesar las imágenes S-2, la exactitud temática lograda en la cartografía, así como el aumento, mantenimiento o retroceso de los bosques y sus principales causas a nivel mundial. Como resultados se encontró que Random Forest (RF) es el clasificador más utilizado para el procesamiento digital de las imágenes S-2, el cual logra en la mayoría de los casos una exactitud temática superior al 85%. En los trabajos multitemporales, se ha encontrado que la cobertura boscosa en Sudamérica y África se ha visto disminuida por actividades como la agricultura y ganadería. Mientras que, en algunos países asiáticos la cobertura boscosa se ha incrementado como consecuencia de la implementación de programas de reforestación y manejo forestal comunitario. Por lo que lo resultados sugieren que las imágenes Sentinel-2 presentan un enorme potencial para llevar a cabo el seguimiento continuo y sistemático de la pérdida o ganancia de los bosques en todo el planeta.

Applying parallelism to a bisimulation algorithm to improve efficiency in software testing of time-critical systems
Authors: Betancourt Joan , Ortiz James , Aranda Jesus
Published: January 2024

Time-Critical Systems (TCS) play a crucial role in environments where strict timing constraints are essential to ensure reliability and correctness. Mutation Testing (MT) is considered a valuable strategy for quality assurance of TCS, but it suffers from the equivalent mutant problem, which is known to increase computational cost and reduce confidence in MT. To address this problem, a strong timed bisimulation equivalence (STBE) algorithm can be used when TCS are modeled as Timed Automata (TA). STBE is computationally expensive and can benefit from parallelism. We survey available STBE implementations, identify opportunities to apply parallelism, build an extension that takes advantage of them, and test its effects. The resulting solution is a Java program that receives multiple TAs expressed in UPPAAL format and determines which TAs are equivalent using an STBE implementation such as TimBrCheck or MUTES  and process-based parallelism. Compared to existing solutions, our tests show that our proposal is more efficient, reducing the runtimes of STBE by more than half. This could improve the reach, reliability, and effectiveness of MT for TCS.

Published: January 2024

The paper analyzes how protease inhibitors of fodder plants with different genotypes influenced the physiological state of the potato ladybird beetles that fed on them. Feeding on plants with resistant genotypes leads to malnutrition in phytophagous insects because the nutrient absorption is impaired by the inhibitors of digestive enzymes. This results in a slowdown in the developmental timing and fat accumulation and the induction of various developmental disorders during the ontogeny to the extent of the cessation of vital functions.

The test method underwent validation to ensure it could accurately identify specific elements, detect minimal quantities, establish the lowest measurable amounts, maintain linearity, demonstrate precision, achieve accuracy, and suitably handle sample solutions and the system.” and the developed test method is suitable and can be introduced into the routine use for the detection of caspofungin acetate and its related substances.
Methocarbamol Transferosomal Gel For Topical Delivery: In-vitro, Ex-vivo and In-vivo Evaluation
Authors: B E Hima , Radha GV
Published: January 2024

Because of their capacity to permeate across the stratum corneum’s barriers to penetration, transferosomes are one of the vesicular transporters that have recently attracted a lot of research and attention. The current study aimed to analyze and improve methocarbamol transferosomal transdermal gels. Reverse phase evaporation was used to create thirteen different formulations of methocarbamol-loaded transfersomes. Using face-centered central composite designs, the influence of independent process variables, like soy lecithin content and surfactant concentration, on dependent variables, such as entrapment effectiveness and the vesicle size of methocarbamol transfersomes, was assessed. The ex-vivo permeation flux of methocarbamol and the lipid to surfactant ratio/skin absorption efficiency of the drug and transferosomal gels were optimized. The optimized formulation showed an entrapment efficiency of 95%, a vesicle diameter of 428 nm, a drug content of 96.6% and a zeta potential of −28.9 mV. In-vitro and ex-vivo drug release rate in optimised gels was found to be 86.43 and 84.12% for 24 hours, respectively. This tranferosomal delivery method for transdermal methocarbamol may be preferable to the standard of care.

Authors: Sarangi Sheetal , Senghor K. A. Arul , V. M. Vinodhini
Published: January 2024

Objectives:

Sarcopenic obesity is defined as age-associated histological changes and adiposity in muscles that impair muscle function. Asian Working Group for Sarcopenia suggested hand grip strength (HGS) and gait speed for screening sarcopenia. Troponin is a putative biomarker of muscle health. The study aims to evaluate Trop T, HGS, and waist circumference (WC) as markers of sarcopenic obesity in postmenopausal women.

Materials and Methods:

An analytical cross-sectional study was conducted in healthy postmenopausal women. Anthropometric measurements, HGS, and gait speed were documented. Postmenopausal women were identified as sarcopenic obesity with the following criteria: (a) The cut-points for weak handgrip strength (kg) for women as <18 in Asians (b) WC ≥85 cm in women. Total cholesterol, triglycerides, high-density lipoprotein (HDLc), low-density lipoprotein (LDLc), and high sensitive troponin T levels were estimated in the automated biochemistry analyser.

Results:

About 33% sarcopenic obesity was observed in postmenopausal women aged 56 to 60 years. WC (93 cm) and body mass index (29.64) were increased in sarcopenic obese. Decreased HGS (9.44 kg) and increased gait speed (13.62 s) were observed in sarcopenic obese as compared to non-sarcopenic obese women. Increased troponin T (0.068 ng/mL), small dense LDLc (mmol/L), LDLc, non-HDLc, and decreased HDLc were observed in sarcopenic obese postmenopausal women. Receiver’s operating characteristic curve: sensitivity of waist circumference, HGS, gait, and troponin T were 97% (area under the curve [AUC] 0.76), 83% (AUC 0.84), 82% (AUC 0.76) and 67% (AUC 0.77), respectively.

Conclusion:

Measurement of waist circumference, hand grip strength, and gait are diagnostic tools of sarcopenic obesity that divulges the quality of postmenopausal life.

INVESTIGATION OF THE POTENTIAL OF WASTE BONES AS A CATALYST IN BIOFUEL PRODUCTION
Authors: Chukwuemeke U Wisdom , Eyankware U Ruth Oghenerukevwe , Egwunyenga Michael Chika
Published: January 2024

It has recently come to light that inappropriate waste management (particularly of animal bones) is a major contributor to environmental degradation on a global scale. Instead, it would be extremely beneficial to the economy if the bioeconomy civilization could find novel applications for these discards. Biodiesel’s output can be put to good use as a heterogeneous catalyst in the effective recycling of animal bone. Ca-based catalysts produced from discarded bones, have been extensively studied in the transesterification reaction due to their high catalytic activity and abundant feedstock. Calcium oxide, a common mineral, can be used to create heterogeneous catalysts (in the form of discarded bones). However, process improvements are required to make calcium oxide-based catalysts suitable for industrial use. This research summarizes the sources of waste animal bones, provides context for the recent advances in the development of various Ca-based catalysts derived from waste animal bones, characterized a calcium oxide-based catalyst derived from waste animal bones, and details its application in biodiesel production. In this work, waste bones were modified by calcination at 9500C for 3h. The catalyst was analyzed using scanning electron microscopy (SEM) for its morphological structure, Fourier transform infrared spectroscopy (FTIR), for its functional group, X-ray fluorescence (XRF), for its elemental composition, thermogravimetric analysis (TGA), for thermal stability and Brunauer Emmett Teller (BET) surface area analysis. Overall, raw sample was found to have no effect on the waste bone, while high temperature calcination greatly affected the pore size, surface area, composition, and thermal decomposition profile of the waste bone sample. According to the study’s findings, used animal bones can be used to create catalysts that are appropriate for trans-esterifying a variety of oil sources into high-quality biodiesel. This increases the total energy and atom-efficiency of both conventional and new chemical processes while also making the system more cost-effective and ecologically benign. This discovery will encourage scientists to look into possible wastes of bones and pave the way for a more cost-effective and ecologically friendly way to make biodiesel and should also continue to be evaluated for the likelihood of their use in the commercial sector.

The treatment consisted of combination of five different hybrid varieties (C1415, MM1107, RH-10, JKMH502 and CP808) and three plant densities (111,111 plants/ ha, 66,666 plants/ ha and 47,619 plants/ ha). The study revealed that variety MM1107 produced highest biomass yield (85.21ton/ha) which was significantly superior over other varieties. MM1107 had higher biomass yield due to higher plant height, leaf area, leaf area index, fresh weight per plant and moisture content and was also better in terms of emergence percentage. Highest biomass yield (91.68ton/ha) and dry matter yield (38.39ton/ha) was found at plant density of 111,111plants/ha. A positive linear relationship was found between silage biomass yield and plant density within the range 47,619-111,111plants/ha. Therefore, variety MM1107 and plant density of 111,111plants/ha performed better for silage production in Dang.

Addition of poultry Manure (PM) to a piece of land at a given rate has been speculated to enhance Amaranth yield, increase land-use and improve soil quality. To address this speculation, the residual effects of Cured Poultry Dropping (CPD) and uncured Poultry Dropping (UPD) at different rate of application (0, 50, 100 and 150 kg N/ha) were evaluated on Amaranth (Amaranthus viridis) production during two growing seasons at the Teaching and Research Farm, University of Ibadan. The effects of CPD and UPD on the yield of Amaranth and some post cropping soil properties were assessed. 150 kg N ha-1 UCP had higher fresh and dry biomass yield (12.14 t/ha and 1.94 t/ha) in dry season, while 100 kg N ha-1 CPD gave better yield (19.6 t/ha and 3.98 t/ha) at wet season. The post soil chemical properties showed that 150 kg N ha-1 CPD by standard deviation increased the organic carbon (43.1 g/kg), nitrogen (9.4 g/kg), phosphorus (55 mg/kg), and Calcium (9.5 Cmol/kg) content at dry season. While100 kg N ha-1 CPD increased the nitrogen (9.6 g/kg), organic carbon (36.1 g/kg), phosphorus (56 mg/kg) content at wet season. Although, there was significant difference amongst the rates of application in terms of yield at dry season, CPD still left the soil in better condition for subsequent cropping.

Published: January 2024

The alarming increase in municipal solid waste (MSW) generation and its complex characteristics pose a significant threat to people and the environment worldwide. The success of solid waste management (SWM) depends on the involvement and active participation of all stakeholders, and in particular, the people in households play a vital role. The primary objective of this paper is to assess awareness, perception, and participation and suggest how an effective SWM can be achieved. Hence, the article aims to present the participation and perceptions of people with regard to the current Municipal Solid Waste Management System (MSWMS) in Mangalore City Corporation, Karnataka State, India. The feedback from 410 people from various households was collected based on gender, age, income, education status, etc. The Statistical Package for Social Sciences (SPSS) was used to analyze these datasets. The study shows that there is variation in the participation of people in all wards, and in some wards it is not satisfactory. It identifies areas where participation is lacking and highlights a potential gap between public perception and the actual state of waste management. The study suggests the need for administrative improvements and strategies based on public feedback to enhance the solid waste management system.

The objective of this study was to determine the impact of municipal solid waste (MSW) treatment techniques on the soil Chemical properties of Sudan Savannah, Nigeria. MSW was collected from multiple metropolitan sites and mixed together. The composite sample was used to produce biochar and compost treatments. The effect of MSW treatment techniques on the qualities of soil was assessed by applying treatments and controls (untreated MSW) to soil at various rates. Soil samples were collected four weeks after treatment application, processed and analyzed in the laboratory. Results showed significant difference (*P≤0.05) in soil Mg and Zn, as well as highly significant difference at (**P≤0.01) in soil EC and K values. Biochar is recommended for acidic soil to improve soil pH, whereas compost is suggested for increasing soil organic matter and microbial activity. The use of untreated MSW is primarily advised for long-term soil deterioration solutions.
