Pobreza, adaptación sociocultural al ambiente y auto-reproducción de la familia campesina en México
Authors: Arriaga Ornelas José Luis 
Published: November 2023

El artículo ofrece un abordaje antropológico sobre un fenómeno que está en curso en México: la transformación cualitativa del modo de vida campesino que estaba anclado en las relaciones con la tierra. Se aborda desde el ángulo de los flujos de energía e información que sostienen la vida. Se busca no simplificar el tema al separar, con fines analíticos, lo que en la realidad está unido: el hombre es un ser biológico, pero al mismo tiempo un ser cultural.
Como principales resultados se muestran algunos indicios de la transformación de los patrones culturales que controlan los flujos de energía, especialmente en el ámbito de la alimentación, en algunas comunidades rurales mexicanas, con presencia indígena y alta marginación.
Biblijne podstawy sakramentalnej interpretacji Listu św. Jakuba 5, 13–16
Authors: Głuchowski Robert 
Published: November 2023

Sobór Trydencki określił sakrament namaszczenia chorych jako „prawdziwy i we właściwym znaczeniu tego słowa sakrament, ustanowiony przez Chrystusa naszego Pana i ogłoszony przez św. Jakuba Apostoła” (DS 1716). Określił również, że „starsi Kościoła”, których św. Jakub zaleca wezwać do namaszczenia chorego (Jk 5, 14), to „kapłani wyświęceni przez biskupa” (DS 1719). Autor niniejszego artykułu odpowiada na pytanie: jak pogodzić te twierdzenia ze współczesną wiedzą biblijną na temat Listu św. Jakuba 5, 13–16. Dziś wiemy bowiem, że List Jakuba powstał zaraz po połowie I wieku, gdy nie wykształciła się jeszcze kościelna hierarchia i nie funkcjonowało pojęcie sakramentu. Analiza dokonana jest w dwóch etapach. Pierwszym jest semantyczna analiza fragmentu 5, 13–16. Drugim etapem – bazującym na wnioskach analizy semantycznej – jest odpowiedź na pytanie: Czy obrzęd ukazany w tym fragmencie jest przez autora listu pojmowany jako szczególny ryt kontynuujący działanie Jezusa.

1 RESUMO

A região do nordeste é a maior produtora de coco verde, motivada pelo uso da irrigação, a qual tem como critério de ser cada vez mais eficiente a longo dos anos. O objetivo desse trabalho foi estimar a evapotranspiração real diária pelo modelo METRIC (Mapping evapotranspiration at high resolution with internalized calibration) parametrizado utilizando dados espectrais de imagens de satélite do Landsat-8 e dados meteorológicos, e comparar as estimativas da Evapotranspiração real diária (ETa) com o método de Penman-Monteith, em uma área implantada com coqueiro-anão irrigado no município de Sousa, PB. A ETa foi estimada a partir da densidade do fluxo de calor latente, obtida como resíduo do balanço de energia pelo modelo METRIC parametrizado, que inclui em sua implementação, calibração radiométrica, cômputo da reflectância e de variáveis biofísicas, balanço de radiação, fluxo do calor no solo e processos iterativos parametrizados para obtenção do calor sensível. O saldo de radiação, fluxo do calor no solo e evapotranspiração real estimados pelo METRIC parametrizado permitiram a obtenção da influência da sazonalidade nas épocas do ano e da condição hídrica na cultura do coqueiro-anão irrigado. O METRIC parametrizado apresentou eficácia na estimativa da evapotranspiração real diária na cultura do coqueiro irrigado no período de estiagem.

Published: November 2023

The influence of electromagnetic field (EMF) on the corrosion of low-carbon steel 20 in mineralized water environment in the presence of hydrogen sulfide and carbon dioxide has been studied. It is shown that EMF accelerates high corrosion by 1.27 times, while local corrosion slows down and the specific number of local corrosion sites decreases. By the method of X-ray photoelectron spectroscopy (XPS), the main corrosion products are obtained. Using the XPS method, it has been established that in addition to the layer of corrosion products formed in place of the dissolved metal, a layer of sedimentary deposits from FeCO3 and CaCO3 crystals is formed.

Published: November 2023

Development of hard-to-recover reserves in low-permeable oil deposits is one of the main sources to maintain resources base in light of continuous depletion of conventional reserves. Meanwhile, the new development zones tend to have an even worse reservoir characteristic, which leads to the evolution of field developments strategies.
In particular, vast amount of hard-to-recover reserves are located in the areas where reservoir pressure maintenance by water injection is inefficient and, therefore, these deposits are developed on depletion regime which evolves into solution gas drive when reservoir pressure drops below saturation pressure. The efficient planning of field development in these cases is complicated by the uncertainties in production forecast associated with models parameters describing the multiphase flow.
This study presents the analyze the impact of the parameters, describing relative permeability on gas-oil system, on the history matching quality and the production forecast in low-permeable reservoirs that are developed under solution gas drive regime.
The main tasks of the study were the following:
- analyze the typical shapes of relative permeability curves applicable for description of different multiphase flow regimes, namely solution gas drive when the gas liberated from oil forms a continuous media and the gas injection when gas phase in introduces from the external source;
- evaluate the possibility to perform an accurate history matching using different types of relative permeability curves;
- evaluate the impact of relative permeability curves modifications on the production forecast in the reservoir simulation models.
The results of the study can be used in field development projects for evaluation of production potential of low-permeable reservoirs developed under depletion regime with the decrease of in-situ pressure below bubble point.

Authors: Azmetov Kh. A. , Khasanov R. R. , Shaibakov B. R. 
Published: November 2023

Overhaul with pipeline lifting is one of the most frequently used repair methods in pipeline system technical operation in the oil and gas industry. Using this repair method, the anti-corrosion protective outer coating that has lost its protective properties is replaced. If necessary, pipe walls are repaired. Organizations operating pipelines are equipped with modern methods and means for determining the technical condition of the protective coating and the pipes themselves. The technical operation system allows timely detection of defective sections and carrying out appropriate repairs, ensuring reliable and efficient pipeline operation. At the same time, the overhaul of the pipeline, especially with its lifting, is an important and complex technological process. Pipeline lifting leads to the appearance of additional stresses in the pipe walls, which were not taken into account at the pipeline design stage. These stresses are added to the stresses from the temperature difference and pressure in the pipe cavity of the pumped product. The total stresses, taking into account the actual technical condition of the operated pipelines, can reach significant values that affect the strength of the pipelines and the safety of the overhaul. At the same time, regulatory documents for pipeline technological parameters calculating do not take into account the forces and stresses in the pipe wall from the effects of temperature differences and pressure in the pipe cavity. In this regard, it is necessary to improve the existing pipeline technological parameters of the overhaul with lifting, taking into account all loads and impacts, as well as the strength of the pipes and the safety of the overhaul.
In addition, in well-known calculations, the required lifting height of the pipeline at the place of installation of cleaning and insulating machines is not the initial parameter, which complicates the provision of the specified lifting height in order to create normal operating conditions for the machines.
The purpose of the work is to ensure the strength of pipes and the safety of overhaul with lifting of the existing pipelines based on the improvement of the calculation of repair technological parameters. Improving the calculation includes taking into account the longitudinal forces acting in the pipeline when it is lifted and taking the required lifting height at the places of installation of cleaning and insulating machines as an initial parameter.
Research methods - analysis and theoretical studies of the stress-strain state of the existing pipeline when it is lifted by pipe-laying machines.
The dependences of the technological parameters of a overhaul with pipeline lifting on the longitudinal forces acting in the pipeline in the lifting section and lifting heights at the places of installation of machines for pipeline cleaning and insulating are obtained.

Backgraund. Pneumolysin (Ply) is a hemolytic toxin of Streptococcus pneumoniae (S. pneumoniae) expressed by all strains of pneumococci. The use of sandwich enzyme-linked immunosorbent assay (ELISA) can be a simple, fast and effective way of its qualitative and quantitative determination in biological fluids.Aim. To develop and evaluate the specificity of sandwich ELISA test system for qualitative and quantitative determination of recombinant Ply (rPly) of S. pneumoniae.Materials and methods. Immobilized on the solid phase rabbit’s polyclonal antibodies (pAbs) to rPly were used as recognition antibodies in sandwich ELISA. The studied antigens were added to the pAbs (rPly). The reaction was manifested by using detecting mouse monoclonal IgG1 (rPly) – antibodies conjugated with horseradish root peroxidase. The specificity of the test system was evaluated when using recombinant α-hemolysin (rα-Hly) and water-soluble S. aureus antigens as reference preparations.Results. Using sandwich ELISA, rPly was detected at a concentration of 0.15 µ / ml. The test system was characterized by specificity, which was confirmed by the absence of reaction with recombinant rα-Hly of Staphylococcus aureus (S. aureus). Reference preparations of water-soluble surface antigens of S. aureus strains No 209, 1986,1991 and Cowan I gave a false positive reaction due to the presence of protein A (SpA) in their composition, a thermostable surface protein expressed by many strains of staphylococci capable of binding immunoglobulins via Fc-fragment or Fab fragments of the V3H domain of the B cells receptor. A negative reaction was obtained with antigens from the S. aureus wood 46 strain, which does not have the spa gene encoding SpA expression. The presence of protein A in preparations of water-soluble S. aureus antigens was confirmed in the ELISA inhibition assay.Conclusion. Sandwich ELISA has been developed for qualitative and quantitative determination of S. pneumoniae Ply. The conducted studies have confirmed the specificity of the test system.

Divergent Reconstructions of Aristotle's Train of Thought: Robert Grosseteste on Proclus' 'Elements of Physics'
Authors: Kiosoglou Socrates-Athanasios 
Published: November 2023

The present paper discusses Grosseteste’s reception of Proclus’ Elements of Physics (EP) in his Commentary on Aristotle’s Physics VI. In the first section I examine the method with which Grosseteste reconstructs Aristotelian texts. The second section initiates a study of the way Grosseteste evaluates Proclus’ EP on the basis of this method. Thus, the third section brings out Grosseteste’s moderate criticism of Proclus’ treatment of certain Aristotelian conclusiones and assumptions. The fourth section extends this study to the conceptual relation between contiguity, continuity and succession. Finally, Grosseteste’s evaluation of Proclus’ tendency to omit, divide and merge Aristotelian conclusiones is studied in the fifth section. I conclude that Grosseteste is a careful and moderately critical reader of Proclus. He aptly grasps the dependence of the EP on Physics VI and conceives of Proclus’ EP as a forerunner of his own method of reconstructing Aristotelian texts.
Redox evolution during arc magma differentiation revealed by mineral/melt Fe3+ and Fe2+ partitioning
Authors: Huang Fangfang , Wang Jintuan , Xiong Xiaolin 
Published: November 2023

Abstract
The oxidizing capacity of volcanic gases relies on both the redox state of the mantle and the redox evolution of mantle-derived magmas. Arc magmas transfer abundant volatiles from the mantle and undergo extensive differentiation before degassing. But how the magmatic redox state evolves during differentiation remains enigmatic. The redox evolution of a magma depends on the mineral/melt partition coefficients of Fe3+ and Fe2+ (DFe3+ and DFe2+). However, no systematic DFe3+ and DFe2+ are reported due to the difficulties in analyzing Fe3+ of silicate minerals. Here, we conducted hydrous experiments at 900−1100 °C and 1−2 GPa and determined systematically DFe3+ and DFe2+ using a novel method. With the obtained partition coefficients, we investigated the redox evolution by performing fractional crystallization modelling. The almost invariable redox state during arc magma differentiation implies an oxidizing mantle predated the Great Oxidation Event if it was triggered by the increasing oxidizing capacity of volcanic gases.

Published: November 2023

Abstract

The milling of micro-channels is a critical step in many of today’s electronics. In this study, the most appropriate trochoid geometry and machining strategy was determined for the milling of micro-channels. For the milling of the channel, various cutting direction strategies were used and 26 different geometries were created to figure out the best strate- gies. Using simulation results on four machines, which have different control units, the best geometry and NC output format were determined from each group with reference to the processing times. Experiments were carried out with a tool having a diameter of 0.8 mm. This tool cut a total of 3 channels of 1.2 mm width, 1 mm depth and 10 mm length. The channels were cut on DIN 2738 (40 CrMnNiMo8-6) material to determine optimum geometry by using the 4 geometries selected from the groups according to the simulation results. In current study, force, tool wear, geometric accuracy and surface roughness were evaluated. After the investigation, the appropriate trochoid geometry and machining strat- egy were determined. As a result, a reduction of about 67.5% was observed in the length of the tool path compared to the conventional method. In addition to the reduction in tool path length, the wear of the tool could be seen in the size of 20 µm*10 µm when viewed from the tool face profile.

Abstract
Noise has become the world's second-largest environmental risk factor1-3. The simultaneous achievement of ultra-broadband and perfect acoustic absorption is a quite vital yet long-standing challenge4-11. Herein, we propose a new "gradient pore circulation (GPC)" strategy for building hierarchical ordered architecture of bioaerogels, by using highly active microfibers precisely dissociated from the wood S2 sublayer as basic units. The bioaerogels comprise anisotropic parallelly-layered microchannels, enriched with intricate multilevel pores within each layer, alongside abundant spring-shaped strips bridging these adjacent layers. Under the “GPC” strategy, the soundwaves effortlessly enter the parallelly-layered microchannels possessing moderate flow resistance, while the synergy of long microchannels, multilevel pores, and abundant interlamellar strips create plentiful closed loops, fostering a repetitive cyclic reflection‒friction‒dissipation of soundwaves. The bioaerogels achieve near-perfect acoustic absorption abilities, with a sound-absorption-coefficient of 0.95~1 across an ultra-broad frequency range of 520‒6300 Hz and a superb noise-reduction-coefficient of 0.82, the highest recorded to date. More importantly, the sound absorption properties retain almost unchanged at extreme temperatures (‒60~+60 ºC) over three months. The revolutionary bioaerogels hold great promise as sustainable sound absorption materials for diverse applications.
The Comparison of Placental Findings and Pregnancy Outcomes Before and During COVID-19 Pandemic

Published: November 2023

Abstract
Background: During the SARS-CoV-2 pandemic, pregnancy outcomes remain in question with relationship to individuals who tested positive for COVID-19. There is a plethora of evidence that pregnant people who become infected with the SARS-CoV-2 virus may be at increased risk for perinatal loss. These losses are believed to be due to the destruction of the placenta, which then deprives the fetus of oxygen.
Objective: This study aimed to compare placental findings and fetal outcomes between two 18-month periods, pre-COVID-19 and COVID-19, and to determine if there was an increase in abnormal placental findings and fetal complications during the COVID-19 period. The study hypothesized that pregnant individuals with COVID-19 positivity would have a higher risk of intrauterine fetal demise and FGR due to placental injury caused by the virus.
Study Design: The placental findings and fetal outcomes of 34,102 deliveries were retrospectively compared between two equal seasonal 18-month timeframes. The COVID-19 period was April 1, 2020, to September 30, 2021. The pre-COVID-19 period was April 1, 2018, to September 30, 2019, with a wash-out period of October 1, 2019, to March 31, 2020. Chi-squared statistical tests with odds ratios and 95% confidence intervals were used to contrast three placental findings and two fetal outcomes.
Results: The study found a significant increase in chorangiosis, chorioamnionitis, villitis, and FGR during the COVID-19 period compared to the pre-COVID-19 period. Additionally, there was a higher incidence of chorangiosis, chorioamnionitis, villitis, and marginally higher FGR in placentae from mothers with a history of COVID-19 infection compared to those without a positive test. There was no significant increase in intrauterine fetal demise among COVID-19-positive mothers.
Conclusion: The study concludes that antenatal testing is not warranted solely for positive COVID-19 infection without other comorbidities present because there was no significant increase in intrauterine fetal demise. However, the study found a rise in FGR among pregnant individuals with a positive COVID-19 test. We agree with the Society for Maternal-Fetal Medicine's recommendations that a repeat fetal growth ultrasound should be conducted four weeks after a positive COVID-19 test. We acknowledge that chorangiosis can occur due to other maternal comorbidities. In the absence of data regarding maternal demographics, we cannot conclude whether chorangiosis occurred due to COVID-19 or other conditions.
