Центральная часть Алдано-Станового щита Сибирской платформы характеризуется разнообразием магматических комплексов со сложной и длительной историей формирования. В связи с наложенными процессами метаморфизма, изменившими первоначальный облик пород, проблема расчленения и корреляции комплексов, геодинамического районирования на вещественной основе далека от решения. В этой статье описаны вещественные характеристики унгринского магматического комплекса близкого по возрасту образования к палеопротерозойской надсубдукционной обстановке. Рассмотрены его вероятные аналоги среди других магматических комплексов и нерасчленённых ортопород, уточнена площадь распространения. Сделан вывод о внедрении комплекса после аккреционных событий.
Activated Carbon Electrodes with Improved Sorption Capacity for Supercapacitive Swing Adsorption of Carbon Dioxide
Authors: Bilal Muhammad , Li Jiajie , Landskron Kai
Published: March 2023

Global warming due to anthropogenic CO2 emissions argues for the rapid development of efficient carbon capture technologies. Supercapacitive swing adsorption (SSA) is a gas separation technology that relies on the reversible charge and discharge of supercapacitor electrodes to adsorb and desorb CO2 highly selectively and reversibly. However, thus far SSA only showed low sorption capacity of 70 mmol/kg, and slow sorption kinetics. Herein, we show that the sorption capacity can be substantially increased via the use of carbons with a higher specific capacitance. The highest gravimetric sorption capacity was measured with electrodes made from garlic-roots derived activated carbon valuing 273 mmol.kg-1 having a specific capacitance of 257 F.g-1. In addition, the overall adsorption rate and productivity were improved. Cycling the electrodes for over 100 h showed highly reproducible, reversible CO2 adsorption and desorption behavior. A preliminary technoeconomic and sensitivity analysis is provided to demonstrate the potential of SSA for commercial applications.

Nanoscale metallic glasses offer opportunities for investigating fundamental properties of amorphous solids and technological applications in biomedicine, microengineering, and catalysis. However, the top-down fabrication of metallic glass nanostructure is restricted by the availability of bulk metallic glass; in contrast, the bottom-up synthesis remains rarely explored due to the rigorous formation conditions, especially the extreme cooling rate. Here we develop a kinetically controlled flash carbothermic reaction, featuring ultrafast heating and cooling rates, for the synthesis of metallic glass nanoparticles within milliseconds. Ten permutations of noble metals, base metals, and metalloid (M1-M2-P, M1 = Pt/Pd, M2 = Cu/Ni/Fe/Co/Sn) were synthesized with widely tunable particle sizes and supportive substrates. Through combinatorial development, we discovered a substantially expanded phase space for metallic glass at the nanoscale than that at the bulk scale, revealing an enhanced glass forming ability due to the nanosize effect. Leveraging this effect, we synthesized several nanoscale metallic glasses with elemental compositions that have never, to our knowledge, been synthesized in bulk. The metallic glass nanoparticles show high intrinsic activity in electrocatalysis and heterogeneous catalysis, outperforming crystalline nanoparticle counterparts and commercial precious metal nanoparticle benchmarks.
Quinone-functionalised carbons as new materials for electrochemical carbon dioxide capture
Authors: Hartley Niamh A , Pugh Suzi M , Xu Zhen , Leong Daniel CY , Jaffe Adam , Forse Alexander C
Published: March 2023

The need for cost-effective carbon dioxide capture technology is rapidly increasing. To limit the global temperature increase to 1.5 °C within the next century, the level of CO2 mitigation needs to increase drastically. Current capture technology, i.e., amine scrubbing, provides several challenges that limit widespread deployment: high regeneration energy, high operational costs and degradation issues. An emerging energy-efficient technology that can address some of the limitations of amines is electrochemically driven carbon dioxide capture. For example, redox-active quinone molecules are capable of capturing carbon dioxide following electrochemical reduction, and can then be regenerated upon electrochemical oxidation. Despite great advances in the chemistry of quinones for electrochemical CO2 capture, however, the integration of quinones in carbon capture devices remains an ongoing challenge. Here we present a new class of quinone-functionalized electrodes for electrochemical CO2 capture, using the diazonium radical reaction to graft quinone molecules to a porous carbon surface. By grafting redox-active molecules to this conductive surface, not only is carbon dioxide capture significantly enhanced when the bound quinone species are electrochemically reduced, but the functionalization process also improves the energy storage of the carbon material. Through constant current experiments in the presence of CO2, reversible carbon capture was observed with initial uptake capacities at 0.4 mmol g–1 which stabilizes to 0.2 mmol g–1 over 100 cycles with an energy consumption of 254 kJ mol–1 per cycle. Our facile low-cost synthesis of quinone-functionalised carbons is highly tunable since both the carbon and redox-active molecule can be modified, and our work therefore paves the way for the design and discovery of improved electrode materials for electrochemical CO2 capture.

Published: March 2023

Copper (II) bromide/ N-methylmorpholine N-oxide promoted α-amination of esters in solvent-free condition is reported. The α-amino esters are precursors for α-amino acids. This method provides α-amino esters in 58-83% yields. The polar solvent dimethyl sulfoxide was avoided and the reactions were performed in solvent-free condition. NMO successfully oxidizes Cu(I)Br to regenerate the Cu(II)Br catalyst. The isolated CuBr2 catalyst was recycled twice.

A new generation of chiral gold(I) catalysts based on variations of complexes with JohnPhos-type ligands with a remote C2-symmetric 2,5-diarylpyrrolidine have been synthesized with different substitutions at the top and bottom aryl rings: from replacing the phosphine by a N-heterocyclic carbene (NHC), to increasing the steric hindrance with bis- or tris-biphenylphosphine scaffolds, or by directly attaching the C2-chiral pyrrolidine in the ortho-position of a dialkylphenyl phosphine. The new chiral gold(I) cata-lysts have been tested in the intramolecular [4+2] cycloaddition of arylalkynes with alkenes and in the atroposelective synthesis of 2-arylindoles. Interestingly, simpler catalysts with the C2-chiral pyrrolidine in the ortho-position of a dialkylphenyl phosphine led to the formation of the opposite enantiomers. The chiral binding pockets of the new catalysts have been analyzed by DFT calcula-tions. As revealed by NCI plots, attractive non-covalent interactions between substrates and catalysts direct the specific enantiose-lective folding. Furthermore, we have introduced the open-source tool NEST, specifically designed to account for steric effects in cylindrical-shaped complexes, which allows predicting experimental enantioselectivities in our systems.
Virum Volitare Per Ora: Genre And Poetic Immortality In Vergil’s Georgics
Authors:   , Aldiss Callum
Published: March 2023

It is a curious thing that the poet who once demurred in Callimachean fashion to sing reges et proelia (Ecl. 6.3) should begin his magnum opus with a bold declaration of generic allegiance to Homeric epic: arma uirumque cano (Aen. 1.1). It must have struck Vergil too. For, in the poem which falls between these two works, the Georgics, he engages in an extended self-referential discourse to explain the evolution of his poetic programme. The poem’s metageneric discourse is central to its meaning. And so, in this thesis, I will explore how Vergil reconciles his earlier aesthetic commitment with his intention to compose epic. Critical to his poetic self-fashioning is the notion of poetic immortality, and the desire to be a Roman poet by writing on Roman themes.

Published: March 2023

An experiment was conducted to evaluate the inclusion effects of Dried Brewery Spent Grain (DBSG) to know its effect on growth performance and meat quality on poultry. Completely randomized design was used to compare the treatments in five replications. The treatments used were 15% DBSG (T1), 20% DBSG (T2), 25% DBSG (T3), Commercial feed (T4) and (0% DBSG) scavenging bird was used as a control. Each treatment contained 10 birds including 200 chickens in the whole investigation. The major factors body weight, carcasses and organs weight, cholesterol, total protein, albumin, and calcium were evaluated. Results showed that mean body weight of the experimental bird after 60 days was not significantly different (p>0.05) among the dietary treatments, i.e., T1 (781.46 g), T2 (738.36 g), T3 (728.91 g) and T4 (753.38 g). Carcass, breast muscle, thigh, wing, shank, liver and spleen were not significantly different (p>0.05) in weight between DBSG included diet and commercial feed. However, dressing percentage (59.3%) of T4 and gizzard (43.20 gm.) in T3 was significantly higher than other treatments. The significantly higher (p<0.05) amount of cholesterol found in T4 (312.01 mg/dl) followed by control diet (239.46 mg/dl), both of which were above than reference range (129-297 mg/dl). However, in other treatments i.e., T1, T2 and T3, the cholesterol content was in between the reference range. Similarly, same level (p>0.05) of total protein, albumin and calcium content in blood serum observed in BSG included diet and commercial diet. Hence, 15% to 20% inclusion of BSG could be the optimum level in diets of New Hampshire chickens.

Published: March 2023

Okra (Abelmoschus esculentus cv. Arka Anamika) is one of the most widely grown vegetable crops in the tropics during the spring, summer, and Kharif seasons. One of the major constraints of low productivity of okra and soil deterioration is due to the inappropriate and sole use of synthetic fertilizer. So, to address the yield gap, an experiment was conducted in Gokuleshwor, Baitadi Nepal from 23rd March to 15th July 2021 to study the effect of integrated nutrient management (INM) on growth, and yield and soil nutrient status in okra". The experiment was laid out in a randomized complete block design (RCBD) with 8 treatments and 3 replication T8 gave maximum plant height (37.21 cm), stem diameter (4.04 cm), numbers of leaves (14.33), and a number of pods (8.07) and minimum plant height (23.18 cm) and a number of leaves (9.00) were observed in T3 whereas minimum steam diameter (2.87cm) a and number of pods (2.87) were observed in T6. It was observed that treatment T8 produced a maximum yield (2.10 kg) and treatment T3 produces the minimum yield (1.24 kg). Highest post-harvest available nitrogen (0.1167%), phosphorus (85.20 kg/ha), potassium (229.61 kg/ha), organic matter (2.31%) and pH (6.25) was found in treatment T8. This study suggests integrating vermicompost and synthetic fertilizer as a potential source for better growth, and high yield of okra thus more experiments on dosage optimization and SSNM should be focused onwards for long term sustainability.

Labuan Bajo is a prioritized tourism area, so the presence of Komodo airport is an important component. Therefore, adequate facilities are needed to serve the needs of service users. The research aims to determine the level of service facilities and passenger satisfaction on the departure path of Komodo Airport in accordance with regulations. Observations were made of 100 passengers out of a total of 185,197 passengers. The analytical method used is importance performance analysis (IPA) to measure the level of passenger satisfaction. The results show that the service level of the facilities is in accordance with the regulations, but the departure and check-in counter facilities are not in accordance with the regulations, so it needs to be improved. Based on the IPA analysis, the level of passenger satisfaction shows that in general passengers are satisfied with the existing service facilities with a conformity level of 89.66%, but aspects of area arrangement and the friendliness of the check-in area staff, the number of counters and the number of toilets on the departure route do not give satisfaction to passengers.
Kajian Kapasitas Pompa sebagai Alternatif Solusi Pengendalian Aliran Balik di Kampung Glintung (GWS) Kota Malang.
Authors: Zulbihar Hendy Arifian Mifdar , Sedyowati Laksni
Published: March 2023

The phenomenon of flooding that occurred in Glintung Village (GWS), especially those that occurred in RT 01, RT 02 and RT 03, is a phenomenon that is rarely found in other areas. Usually, floods occur due to high rainfall intensity, causing excess water which cannot be accommodated by waterways, to overflow into floods. The floods in the GWS indicate a backflow phenomenon which causes water that should flow into the river to turn around and overflow into residents' settlements. To anticipate floods due to backflow which have a bigger impact, one effort that can be done to solve this problem is to install pumps to reduce the volume of flooding in the area. So an analysis is needed to determine the required pump capacity to reduce the flood volume. The results of the analysis show that reducing the volume of flooding can be done by installing 3 pumping stations and 3 pumps with a capacity of 100 m3/hour for RT 03, 3 pumps with a capacity of 50 m3/hour, for RT 02 and 1 pump with a capacity of 50 m3 /hour for RT 01. In addition, it is also necessary to install a backflow valve and repair the existing river retaining wall.

Published: March 2023

El arbolado urbano incluye principalmente especies de origen introducido, aunque cada vez es más común el uso de árboles nativos tanto en México como en otras regiones del mundo. El objetivo principal de este estudio fue documentar el uso de taxones arbóreos en las áreas verdes urbanas del noreste de México. Específicamente, se plantearon las siguientes preguntas: ¿Existen cambios en el uso de especies? ¿A qué se deben esos cambios? ¿Cuál es la tendencia futura en el uso de especies? Para ello, se realizó una búsqueda en internet de artículos sobre el tema en los sitios: ISI Web of Knowledge, EBSCO, SCOPUS y Google académico. Los resultados indicaron que sí hubo cambios en los taxa utilizados. Se identificaron tres periodos: el primero de 1850 a 1980 en el cual se utilizaban, principalmente, especies introducidas como Fraxinus americana y Ligustrum lucidium; de 1980 a 2000, cuando se inicia el uso de taxones nativos como Quercus fusiformis; y del 2000 a la actualidad, en el que se consolida el empleo de especies nativas producidas en viveros locales como Ebenopsis ebano. Los aspectos que detonaron esos cambios fueron las experiencias con las heladas, la generación de evidencia por parte de los académicos, la consolidación de los viveristas en la región y la creación y gestión de la Asociación Mexicana de Arboricultura. La tendencia futura apunta hacia la reforestación de las áreas verdes urbanas del noreste de México con especies nativas.

Authors: KELEŞ Ali , GENÇCELEP Hüseyin
Published: March 2023

The aim of this study is to determine the mineral contents of wild edible mushrooms. The potassium (K), magnesium (Mg), calcium (Ca), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), nickel (Ni), cadmium (Cd) and lead (Pb) contents of twenty four edible mushrooms, collected from East Black Sea Region, Türkiye, were analyzed. The studied mushrooms varied widely in their content of both essential and toxic deleterious elements. The minimum and maximum mineral contents of mushrooms were determined as mg/kg dw for K (4573-15645), Mg (173-1421), Ca (24-711), Mn (5.34-90.64), Fe (44.78-236.95), Zn (24.81-119.03), Cu (11.02-174.01), Ni (0.95-2.86), Cd (0.05-22.57) and Pb (0.01-2.07). The potassium content was found to be higher than those of the other minerals in all the mushrooms. In addition to the metal contents, the daily intakes of metal (DIM) and Health Risk Index (HRI) values of edible mushrooms were also calculated. Lead and cadmium were present but at concentrations that are not hazardous to human health except for Russula vinosa. The K, Mg, Zn, and Ni concentrations were determined to be high in Russula integra. Mushrooms have become increasingly attractive as functional foods for their potential beneficial effects on human health. Due to the toxic minerals they carry, mushrooms should be taken into consideration during their consumption as human food. The differences and similarities between mineral contents were established by Principal Component Analysis. Also, mushrooms are important in the ecosystem because they are able to biodegrade the substrate and to collect heavy metal.

Published: March 2023

Mouse kidney parvovirus (MKPV) causes inclusion body nephropathy in severely immunocompromised mice and renal interstitial inflammation in immunocompetent mice. Here we sought to determine the effects of MKPV on pre-clinical murine models that depend on renal function. To assess the
effects of MKPV infection on the pharmacokinetics of 2 renally excreted chemotherapeutic agents, methotrexate and lenalidomide, we measured drug concentrations in the blood and urine of MKPV-infected or uninfected immunodeficient NOD.Cg-PrkdcscidIl2rgtm1Wjl/SzJ
(NSG) and immunocompetent C57BL/6NCrl (B6) female mice. No differences in plasma pharmacokinetics were observed for lenalidomide. However, the AUC of methotrexate was 1.5-fold higher in uninfected NSG mice compared with infected NSG mice, 1.9-fold higher in infected B6 mice compared with uninfected
B6 mice, and 4.3-fold higher in uninfected NSG mice compared with uninfected B6 mice. MKPV infection did not significantly affect the renal clearance of either drug. To assess effects of MKPV infection on the adenine diet model of chronic kidney disease, MKPV-infected and uninfected B6 female
mice were fed a 0.2% adenine diet, and clinical and histopathologic features of disease were assessed over 8 wk. MKPV infection did not significantly alter urine chemistry results, hemogram findings, or serum concentrations of BUN, creatinine, or symmetric dimethylarginine. However, infection
did influence histologic outcomes. As compared with uninfected mice, MKPV-infected mice had more interstitial lymphoplasmacytic infiltrates after 4 and 8 wk of diet consumption and less interstitial fibrosis at week 8. Macrophage infiltrates and renal tubular injury were similar between in
infected and uninfected mice. These findings indicate that MKPV infection had minimal effects on the renal excretion of 2 chemotherapeutics and on serum biomarkers of renal function. However, infection significantly influenced two histologic features of the adenine diet model of chronic renal
disease. MKPV-free mice are critically important in studies evaluating renal histology as an experimental outcome.

Published: March 2023

The reappearance of the monkeypox virus in 2022 in 58 countries and Indonesia is no exception, which confirmed 1 case in patients post travelling abroad. The current monkeypox infection is still present, with symptoms that vary from person to person and are typically characterized by reddish rashes. Still, it is primarily confined to the genital, perigenital, and perianal areas. It manifests at various stages of development, in addition to transmission from animals caused by hunting activities or in LGBT ( Lesbian, Gay, Bisexual, and Transgender) communities that have unprotected sex and can be infected through semen and saliva. This review aims to find a relationship between the increasing number of monkeypox cases, especially in LGBT community, based on the literature study approach and case reports. One of the non-medicamentous ways is to reduce travelling abroad, especially in countries with many monkeypox cases. Preventing direct contact, such as abstaining from sex and using condoms, is also a way to reduce the morbidity of monkeypox infection, especially in LGBT community. The treatment has not proven effective, and the available vaccines, especially in Indonesia, are still limited. Only a few cases in Indonesia have been reported.

Green tea contains flavonoids which are the result of metabolism of both plants which are widely distributed in plants. Catechins as the active substance in green tea leaves function as an antibacterial for Staphylococcus aureus which can inhibit the growth of acne. Gel peel off mask is a skin care preparation in the form of a gel and will dry after being applied to the skin. Peel off gel masks can be useful for repairing and treating facial skin from problems with wrinkles, aging, acne and can also be used to shrink pores. The purpose of this study was to determine the best formulation and concentration of green tea leaf extract peel-off gel masks. The research method used is an experimental method, by making a tea leaf extract formulation as a peel off gel mask. The results showed that the green tea leaf extract gel peel-off mask preparation was brown in color, had a distinctive smell, homogeneous and stable, did not irritate the volunteers' skin, and fulfilled the evaluation tests of other preparations. The preference test based on the preference parameter for texture is significant at 0.078 (sig=0.000<0.078), for color is significant at 0.05 (sig=0.000<0.05) and aroma is significant at 0.05 (sig=0.002<0.05). Green tea leaf extract with a concentration of 0.08%, 0.16% and 0.32% can be used as a gel peel off mask formulation. Future researchers are expected to be able to compare the effectiveness of peel off gel mask preparations with a variety of other types of tea and with different concentrations.

Authors: Kuznetsova Kuznetsova , Averchenkova Elena
Published: March 2023

The aim of the study is to form a control subsystem model in the management system of the region’s mineral resource complex. The article is devoted to solving the main task to form a flow diagram for operating the control subsystem in the management system of the region’s mineral resource complex for monitoring indicators of subprogram 1 “Reproduction of the mineral resource base, geological study of the subsoil” within the framework of the Russian Federation state programme “Reproduction and use of natural resources”. The concepts of the set-theoretic approach and the method of mathematical analysis are used in the paper. The work features are forming an algorithm for operating the control subsystem in the management system of the region’s mineral resource complex, using mathematical tools. As a result of the study, the proposed model of the control subsystem in the management system of the region’s mineral resource complex is tested on the example of statistical data on reserves for five types of solid minerals. The adequacy of the obtained model of the control subsystem in the management system of the region’s mineral resource complex is confirmed by the calculations carried out in the work. The simulated control subsystem can be replicated for other types of minerals.

Published: March 2023

Innovative managerial and social changes, such as sustainable marketing practices considerably improve organizational performance. Although the RMG sector of Bangladesh is widely known to global consumers through the ‘Made in Bangladesh’ tagline, effective implementation of sustainable marketing in the country has been proven as a difficult task. This research examines the current state and implications of sustainable marketing in the RMG sector of Bangladesh. Primary data were collected from 20 RMG factories located in Dhaka and Gazipur that were selected using convenience sampling techniques and 120 officials were selected using convenience and snowball sampling techniques. Data were analyzed using the content analysis technique where the theoretical framework was informed by the theory of planned behavior. The research shows that knowledge about sustainable marketing of most factories is limited and often they are not interested in practicing it. It also evidences that RMG manufacturers have been late in emphasizing and adopting sustainable marketing practices. They have not yet started showing concerns in this respect. Lack of supporting information systems often impedes the implementation of sustainable marketing practices. Legal requirements and the mandatory rule for sharing information regarding sustainable marketing work as the main motivations to adopt sustainable marketing practices.
