Authors: Prabhakar Bhavesh , Japee Gurudutta
Published: March 2023

Liquidity analysis is an important measure of a company's financial health, as it indicates the ability of the company to meet its short-term obligations. The main objective of these study to analysing selected cement companies of India: a liquidity scenario perspective. For the period 2012-2013 to 2021-2022. The secondary data is used for the research.  It has been collected from selected ten cement companies’ annual reports. The used tools & techniques: liquidity ratios analysis (current ratio, quick ratio and cash ratio), descriptive statistics analysis, analysis of variance (ANOVA) and Post-hoc Tukey test. It is concluded that there is a considerable variation in the liquidity ratios of the companies in the cement industry. While some companies have a strong liquidity position (e.g., Ambuja Cements Ltd. Shree Cements Ltd. ACC Ltd.), others have a weaker liquidity position (e.g., The India Cements Ltd., The Ramco Cements Ltd. and Prism Johnson Ltd.). Therefore, it is important to evaluate each company's liquidity position based on its specific circumstances and needs. Overall, the 95% confidence interval for the mean values for all three liquidities ratios. which suggests that the true mean values for all three liquidities ratios for all cement companies in the industry is likely to fall within this range. It is also concluded that all the null hypotheses have not been accepted meaning thereby all alternative hypotheses are accepted. There are significant differences between the current ratio, quick ratio and cash ratio of selected cement companies of India.

The rationality of using DNA diagnostics in sports cardiology
Authors: Kadykova A. I. , Zholinsky A. V. , Deev R. V.
Published: March 2023

NGS is becoming an integral part of medical practice, including in cardiology. The role of genes in the formation of diseases of the cardiovascular system has been actively studied for the last 20 years. Currently, heart diseases with a hereditary component are usually divided into two large groups: monogenic syndromes that lead to an unfavorable outcome, including sudden cardiac death at a young age, and polygenic conditions that manifest after 35 years and are accompanied by deterioration in the quality of life. In professional sports, changes in the myocardium are almost inevitable, however, the first phenotypic signs of hereditary myocardial disease may be hidden behind adaptive changes, which are commonly called “athlete’s heart”. The carriage of causative genes radically changes the approach to the management of an athlete: his admission to training and competitive activities is reviewed, the volume of permissible load and the frequency of visits to a cardiologist are discussed. In this paper, we tried to identify clinical markers — «red flags» that would indicate the need for genetic testing on the example of athletes who underwent an in-depth medical examination in 2021–2022.

Published: March 2023

The object of the study: to study the dynamics of erythrocyte parameters in 2nd and 3rd year students with different levels of physical activity.

Materials and methods: the venous blood of 56 students served as the material: 29 girls and 27 boys aged 18 to 22 years. With the help of a questionnaire, all the subjects were divided into 3 groups depending on the level of physical fitness (LPF). The red blood cells (RBC) and mean corpuscular volume (MCV), the concentration of hemoglobin (HGB), hematocrit (HCT), the mean cell hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), the red cell distribution of width (RDW) were determined.

Results: the highest values of indicators HGB, RBC and HCT were observed in students with high LPF. The highest values were recorded of the MCV, MCH, MCHC and RDW With an average LPF. High values of HGB, RBC and HCT with high LPF and indicators of the MCV, MCHC and RDW with average LPF prevailed in the 2nd year. Young men had an increase in the values of HGB, RBC, HCT, MCH with low LPF and an increase in MCV and RDW at an average level in the 3rd year. Statistically significant differences were found between the 2nd and 3rd year girls in terms of RDW with an average LPF.

Conclusion: with an increase in LPF, there is an increase in erythrocyte parameters. The dynamics of erythrocyte parameters depends on the level of physical activity, gender and the course of study.

Authors: Meshtel A. V. , Rybakova P. D. , Miroshnikov A. B. , Vybornov V. D. , Antonov A. G. , Khanferyan R. A. , Korosteleva M. M.
Published: March 2023

Background: Controversial approaches to studying the effect of proteins of various origins on the functional parameters of human skeletal muscles have led to the erroneous opinion that plant-based protein is a lesser stimulator of muscle mass growth and muscle strength than animal protein. Therefore, the purpose of this systematic review was to actually evaluate the effects of plant and animal protein intake on muscle mass and strength through studies comparing protein supplements.

Methods: Literature search was carried out in the databases PubMed, Research Gate and the database of the Russian State Library. Studies were considered both in English and in Russian, over the past 20 years, filtered by date: from July 2002 to July 2022. Inclusion Criteria: Participants are healthy men and women over 18 years of age; taking protein supplements from plant products (soy, wheat, pea, rice, etc.); comparison with a group taking protein supplements from animal products (whey, beef, egg, etc.); studies assessed lean and/or muscle mass and assessed participants' muscle strength before and after supplementation; randomized controlled trial.

Results: A total of 970 studies were found. After initial screening for title and abstract, 938 studies were excluded. Of the 32 publications selected, 5 duplicates were excluded, and after a secondary selection, 18 studies that did not meet the PICOS criteria were excluded. As a result of the search and selection, the review included 9 publications.

Conclusions: Athletes and active individuals who prefer to consume plant-based protein products may not be inferior in terms of muscle strength and muscle mass to those athletes who prefer animal-based protein products. To further explore this topic, more randomized controlled trials should be conducted, taking into account the requirements for standardization and with a large number of participants.

Published: March 2023

Accurate resting metabolic rate readings are essential for dietary planning and body composition monitoring not only for healthy individuals but also for athletes. A number of factors can alter resting metabolic rate during its measurement by indirect calorimetry. The methodology used may affect the results of the study. A clear standardisation of this procedure is needed to obtain the most accurate results.

Purpose: To review the literature to determine the optimal subject condition and methodology for the resting metabolism measurement procedure using indirect calorimetry.

Materials and methods: A literature search was conducted in PubMed, MEDLINE and Cochrane Library databases. The query included key words and logical phrases: “calorimetry”, “indirect calorimetry”, “resting metabolic rate”, “energy metabolism”, “basal metabolism”, “standards”. Only Englishlanguage studies and human studies were considered. Additional information was identified because of the review and included in the review.

Results: the parameters of standardization during the resting metabolism measurement procedure are described: consumption of food, ethanol, caffeine, nicotine; daily activities and physical activity; body position in space and environmental conditions during the measurement; actions of the specialist performing the procedure, etc. The article outlines effective methods for measuring resting metabolism to obtain the most accurate results in both athletes and non-athletes.

Conclusion: an attempt has been made to formulate precise methodological rules for standardization and recommendations for measuring resting metabolism by indirect calorimetry.

Authors: Samoilov A. S. , Zholinsky A. V. , Rylova N. V. , Bolshakov I. V.
Published: March 2023

Objective: to study the indicators of carnitine metabolism in young athletes of various specializations.

Materials and methods: This study involved 46 people with different levels of physical activity aged 15 to 18 years. The first group consisted of 18 girls professionally involved in field hockey (mean age, 16.17 ± 0.31 years). The second group included 21 swimmers (10 girls and 11 boys, mean age 17.00 ± 0.26 years). The control group included 7 young men with a standard mode of motor activity, not involved in sports (the age of the subjects was 16 years). In the course of the study, the method of liquid tandem chromatography-mass spectrometry with ionization in an electrospray was used. The material for research is capillary blood. As a result of the analysis of the material, the concentrations of bound carnitine (acylcarnitines) and free carnitine were determined in µmol/l.

Results: Comparative blood analysis between the three groups showed differences in free carnitine levels. It was shown that the concentration of free carnitine in the blood plasma of field hockey athletes was significantly lower than in the groups of swimmers and non-athletes (p < 0.001). At the same time, the values of indicators of bound carnitine did not differ significantly between all subjects. We also studied that the values of the carnitine coefficient were significantly higher in the group of hockey players compared to other groups (p < 0.001).

Conclusion: The decrease in free carnitine levels in the group of hockey players is probably the result of long-term adaptation of the body to conditions in which glucose is the main energy substrate for working muscles. Further studies are needed to clarify the exact mechanisms of development of this phenomenon.

Authors: Melika keyghobadi
Published: March 2023

Women's needs and expectations in society are changing and evolving now as a result of efforts to reclaim their lost rights and achieve gender justice. In order to understand the cultural-social aspects that contribute to gender disparity, the current research has looked into factors including patriarchal ideology, gender stereotypes, gender socialization, and others. Feminists' conceptions of gender inequality, and Bourdieu's theory have all been used in this study. 385 individuals were chosen as a sample from the married women in Isfahan city who are the statistical population for this study and range in age from 20 to 49. Quota sampling is the technique used in this study. The research's findings show that there is a high level of gender disparity, especially in the economic and cultural spheres, and that there is no correlation between gender stereotypes and inequality, adherence to the patriarchal ideology, or societal norms and inequality. Inequality and gender tolerance exist in the connection.
Production of Methanol Tolerant Cell-bound Lipase of Magnusiomyces spicifer SPB2 and Application as Whole-cell Biocatalyst in Transesterification Reaction
Authors: Srimhan Purimprat , Hongpattarakere Tipparat
Published: March 2023

Cell-bound lipase (CBL) is a potential biocatalyst for production of fatty acid alkyl ester (FAAE), which is feasible replacement for diesel fuel. This study aimed to improve both hydrolysis and transesterification activities of CBL from the yeast Magnusiomyces spicifer SPB2, which could be employed as whole-cell biocatalyst for transesterification reactions through optimizing the growth medium using Taguchi orthogonal array experimental method (L9). The optimized medium, resulting the highest CBL transesterification activity, consisted of soybean oil, peptone, Gum Arabic and an initial pH of 5. Interestingly, the fatty acid methyl ester (FAME) yield increased up to 33.28 times when compared with non-optimized medium. Moreover, cell morphology of M. spicifer SPB2 varied depending on the culture medium component. The single cell was more active to be used as the whole-cell biocatalyst than the pseudomycelial form for transesterification reaction. The highest FAME yield was 93.86 % when refined palm oil to methanol molar ratio of 1:8 was used as substrates. Whole-cell lipase from M. spicifer showed favorable activity to iso-butanol as an acyl accepter, resulting in fatty acid butyl ester (FABE) yield of 86.80 % at 1:3 molar ratio of palm oil to iso-butanol. The FAME and FABE yields dramatically decreased from 93.86 and 86.80 % to 57.02 and 4.48 %, respectively after the reuse of the enzyme to the second batch of reaction. These results indicated that the whole-cell biocatalyst developed from M. spicifer was an efficient and economical approach to improve enzyme activity and stability in the transesterification reaction.
HIGHLIGHTS

Methanol tolerant cell-bound lipase and extracellular lipase of spicifer SPB2 were produced
The whole-cell biocatalyst of spicifer SPB2 was developed for FAME production
The optimized medium was developed to prepare whole-cell lipases from spicifer SPB2
Gum Arabic was the most influencing factor for synthetic activity of whole-cell CBL from yeast
Single cell morphology exhibited higher transesterification activity than pseudomycelial form

Authors: García Ríos Pablo , Del Blanco García Federico Luis
Published: March 2023

El siguiente artículo presenta la reconstrucción virtual de la ciudad utópica de New Babylon, diseñada por el artista Constant Nieuwenhuys entre 1959 y 1974. Pese a la aproximación artística de Constant, New Babylon se convirtió en una referencia para arquitectos y urbanistas en la época de post-guerra, debido a los conceptos que transmitía. Tras la recopilación de la documentación original se ha generado un modelo virtual preciso de un sector de New Babylon. La nueva documentación elaborada ha permitido llevar a cabo un análisis de la ciudad, completando la visión que Constant expresó mediante sus maquetas, dibujos y textos. El modelo se ha exportado a un sistema de realidad virtual. El empleo de motores de renderizado en tiempo real ha permitido visitar la ciudad utópica en primera persona viviendo una experiencia no lineal.

El control de la forma de las bóvedas de crucería a través de la traza de sus nervios fue una estrategia que posibilitó su expansión y desarrollo. Existen actualizadas y rigurosas investigaciones sobre los recursos gráficos que los canteros desarrollaron para la labra y construcción de este sistema, que llegaría a alcanzar una gran sofisticación en el tardogótico, pero hay un mayor desconocimiento de las estrategias geométricas que siguieron los maestros de obras que diseñaron bóvedas con nervios de ladrillo; es en este campo donde quiere profundizar esta investigación a través del análisis gráfico de cuatro casos de estudio construidos en el Reino de Aragón durante época medieval.
Estructuras de apoyo central en estaciones de servicios españolas(1950-70). Análisis gráfico
Authors: Rodríguez Arias Alberto , Amado Lorenzo Antonio , Tarajko-Kowalska Justyna
Published: March 2023

A lo largo del siglo XX, en las estaciones de servicio se ensayaron soluciones arquitectónicas que no siempre se podrían afrontar en obras de mayor escala o compromiso. En los años cincuenta y sesenta, en las gasolineras se fue diferenciando la zona de repostaje de la de servicios, dando lugar a soluciones singulares de cubierta, apoyadas sobre soportes centrales independientes, a medio camino entre la escultura geométrica y el alarde estructural. Las obras de conocidos arquitectos internacionales fueron entonces las referencias buscadas por los arquitectos españoles. En el artículo se estudian casos representativos de las nuevas tipologías y su relación con estaciones similares foráneas. Los análisis gráficos comparativos permiten identificar semejanzas y diferencias, concluyendo que sus autores no se limitaron a transcribir literalmente tales referencias sino que reinterpretaron o adaptaron soluciones ajenas a las limitaciones de un país autárquico que todavía sufría las consecuencias de su Guerra Civil.

Published: March 2023

The findings of this study can inform and enable policymakers in improving occupational air pollution, including addressing air pollution, pollution sources and other related issues in the garment manufacturing sector in Cambodia. Such interventions will help to uphold the health of workers as a human right, ensure safe workplaces, and also be beneficial for the country’s economic growth, as a healthy workforce is more productive. While the garment sector serves as Cambodia’s economic backbone and creates much-needed jobs, it is also a highly polluting industry, alongside being regularly implicated for not upholding labour rights. The sector emits pollutants to air from intensive energy use, solid and hazardous waste emissions, noise pollution and wastewater pollution discharge. Despite this, the sector’s environmental impacts in Cambodia, particularly in relation to air pollution, are not well known, and this gap was highlighted in the development of Cambodia’s 2021 Clean Air Plan. Aiming to fill this gap, in cooperation with SEI, the Air Quality and Noise Management Department of the General Directorate of Environmental Protection of Cambodia’s Ministry of Environment conducted a research project to improve understanding of air pollutant emissions from the textile industry and the health impacts on workers in Cambodia’s garment industry. The study drew on in-depth interviews with 323 garment factory workers across 16 factories, interviews with 16 factory owners, and quantitative data to better understand all interviewees’ experiences with occupational air pollution. While the research documented any symptoms related to air pollution, it did not employ medical research to assess the workers’ health status, nor did it attempt to investigate the cost or impact of air pollution on factory production. This policy briefing draws on a longer report prepared by the Ministry of Environment (Chandath, H., Chhay Por, I., Sokyimeng, S., Dana, S., Raksmey, Y. 2023.

Турбулентность в мировом экономическом пространстве, подогреваемая санкционной риторикой, наглядно продемонстрировала, что обладание ресурсами: природными, интеллектуальными и индустриальными еще не гарантирует устойчивого развития — важнейшую роль сегодня играет инфраструктура доставки продукта или услуги до конечного потребителя.

Turbulence in the worldwide economic space, fueled by sanctions rhetoric, clearly demonstrated - the possession of resources: natural, intellectual and industrial does not yet guarantee sustainable prosperity of any state.

В помощь специалистам, знакомым с устройством реляционных СУБД, планирующим переход на PostgreSQL, издательство «ДМК Пресс» выпустило книгу «PostgreSQL 15 изнутри».

The exodus of western IT vendors from Russia has led to shrinkage of local enterprise database market. The way out is PostgreSQL, with major Russian financial and industrial corporations having migrated to the database without waiting for imported software products to “turn into a pumpkin”. However, it is no typical task for a corporation to maintain an opensource solution, tracking its development and ensuring guaranteed reliability of the system-level code. For PostgreSQL, those tasks are handled by Postgre Professional, a company offering the Postgres Pro database that is included into the Unified Registry of Russian Software Products.

Abstract. The potential future trend in African aerosol emissions is uncertain, with a large range found in future scenarios used to drive climate projections. The future climate impact of these emissions is therefore uncertain. Using the Shared Socioeconomic Pathway (SSP) scenarios, transient future experiments were performed with the UK Earth System Model (UKESM1) to investigate the effect of African emissions following the high emission SSP370 scenario as the rest of the world follows the more sustainable SSP119, relative to a global SSP119 control. This isolates the effect of Africa following a relatively more polluted future emissions pathway. Compared to SSP119, SSP370 projects higher non-biomass-burning (non-BB) aerosol emissions, but lower biomass burning emissions, over Africa. Increased shortwave (SW) absorption by black carbon aerosol leads to a global warming, but the reduction in the local incident surface radiation close to the emissions is larger, causing a local cooling effect. The local cooling persists even when including the higher African CO2 emissions under SSP370 than SSP119. The global warming is significantly higher by 0.07 K when including the non-BB aerosol increases and higher still (0.22 K) when including all aerosols and CO2. Precipitation also exhibits complex changes. Northward shifts in the Inter-tropical Convergence Zone (ITCZ) occur under relatively warm Northern Hemisphere land, and local rainfall is enhanced due to mid-tropospheric instability from black carbon absorption. These results highlight the importance of future African aerosol emissions for regional and global climate and the spatial complexity of this climate influence.

Abstract. The Fenwei Plain, home to 50 million people in
central China, is one of the most polluted regions in China. In 2018, the Fenwei
Plain was designated as one of the three key regions for the “Blue Sky
Protection Campaign”, along with the Beijing–Tianjin–Hebei (BTH) and
Yangtze River Delta (YRD) regions. However, compared to BTH and YRD, our
understanding of the current status of air pollution in the Fenwei Plain is
limited partly due to a lack of detailed analysis of the transformation from
precursor gases to secondary products including secondary organic aerosol
(SOA) and ozone. Through the analysis of 7 years (2015–2021) of surface
monitoring of the air pollutants in Xi'an, the largest city in the Fenwei
Plain, we show that roughly two-thirds of the days exceeded either the PM2.5 or the O3 level-1 air quality standard, highlighting the severity of
air pollution. Moreover, an increase in O3 pollution in the winter
haze was also revealed, due to the constantly elevated reactive oxygenated
volatile organic compounds (OVOCs), in particular formaldehyde, with
an ozone formation potential of over 50 µg m−3, in combination with
the reduced NO2. The abrupt decrease of NO2, as observed during
the lockdown in 2020, provided real-world evidence of the control measures,
targeting only NOx (70 % decrease on average), and were insufficient to
reduce ozone pollution because reactive OVOCs remained constantly high in a
volatile organic compound (VOC)-limited regime. Model simulation results showed that with NO2
reduction from 20 %–70 %, the self-reaction rate between peroxy radicals, a
pathway for SOA formation, was intensified by up to 75 %, while the
self-reaction rate was only reduced with a further reduction of VOCs of
> 50 %. Therefore, a synergic reduction in PM2.5 and
O3 pollution can only be achieved through a more aggressive reduction
of their precursor gases. This study elucidates the status of ozone and
PM2.5 pollution in one of the most polluted regions in China, revealing
a general trend of increasing secondary pollution, i.e., ozone and SOA in
winter haze. Controlling precursor gas emissions is anticipated to curb both
ozone and SOA formation, which will benefit not just the Fenwei Plain but
also other regions in China.
Air–sea gas exchange in a seagrass ecosystem – results from a 3He ∕ SF6 tracer release experiment
Authors: Dobashi Ryo , Ho David T.
Published: March 2023

Abstract. Seagrass meadows are some of the most productive ecosystems in the world and could help to mitigate the increase of atmospheric CO2 from human activities. However, understanding the role of seagrasses in the global carbon cycle requires knowledge of air–sea CO2 fluxes and hence knowledge of the gas transfer velocity. In this study, gas transfer velocities were determined using the 3He and SF6 dual tracer technique in a seagrass ecosystem in south Florida, Florida Bay, near Bob Allen Keys (25.02663∘ N, 80.68137∘ W) between 1 and 8 April 2015. The observed gas transfer velocity, normalized for CO2 in
freshwater at 20 ∘C, k(600), was 4.8 ± 1.8 cm h−1, which was lower than that calculated from published wind speed/gas exchange parameterizations. The deviation in k(600) from other coastal and offshore regions was only weakly correlated with tidal motion and air–sea temperature difference, implying that wind is the dominant factor driving gas exchange. The lower gas transfer velocity was most likely due to wave attenuation by seagrass and limited wind fetch in the study area. A new wind speed/gas exchange parameterization is proposed (k600=0.143u102), which might be applicable to other seagrass ecosystems and wind-fetch-limited environments.

Abstract. The Earth Clouds, Aerosols and Radiation Explorer (EarthCARE) is the combination of multiple active and passive instruments on a single platform. The Atmospheric Lidar (ATLID) provides vertical information of clouds and aerosol particles along the satellite track. In addition, the Multi-Spectral Imager (MSI) collects the multispectral information from the visible till the infrared wavelengths over a swath width of 150 km across the track. The ATLID–MSI Column Products processor (AM-COL) described in this paper combines the high vertical resolution of the lidar along track and the horizontal resolution of the imager across track to better characterize the 3-dimensional scene. ATLID Level 2a (L2a) data from the ATLID Layer Products processor (A-LAY) and MSI L2a data from the MSI Cloud Products processor (M-CLD) and the MSI Aerosol Optical Thickness processor (M-AOT) as well as MSI Level 1c (L1c) data are used as input to produce the synergistic columnar products: the ATLID–MSI Cloud Top Height (AM-CTH) and the ATLID–MSI Aerosol Column Descriptor (AM-ACD). The coupling of ATLID (measuring at 355 nm) and MSI (at ≥ 670 nm) provides multispectral observations of the aerosol properties. Especially, the Ångström exponent from the spectral aerosol optical thickness (AOT 355 nm/670 nm) adds valuable information for aerosol typing. The AOT across track, the Ångström exponent and the dominant aerosol type are stored in the AM-ACD product. The accurate detection of the Cloud Top Height (CTH) with lidar is limited to the ATLID track. The difference of the CTH detected by ATLID and MSI is calculated along track. The similarity of MSI pixels across track with those along track is used to transfer the calculated CTH difference to the entire MSI swath. In this way, the accuracy of the CTH is increased to achieve the EarthCARE mission goal aiming to derive the radiative flux at the top of the atmosphere with an accuracy of 10 Wm−2 for a 100 km2 snapshot view of the atmosphere. The synergistic CTH difference is stored in the AM-CTH product. The quality status depending on day/night conditions or the presence of multiple cloud or aerosol layers is provided with the products. The algorithm was successfully tested using the common EarthCARE test scenes. Two definitions of the CTH from the model-truth cloud extinction fields are compared: An extinction-based threshold of 20 Mm−1 provides the geometric CTH and a cloud-optical-thickness threshold of 0.25 describes the radiative CTH. The first one is detected with ATLID, the second one with MSI.
