Abstract
Taking into consideration the difficulties in predicting the properties of liquid production and evaluating the irreducible water saturation of low-porosity and ultra-low-permeability sandstone reservoirs, the relationships between the irreducible water saturation and logging reservoir evaluation parameters are explored based on a large number of core mercury injection experiment. When the permeability cumulative contribution value reaches 99.9%, the lower limit of pore throat radius is determined as 0.025 μm and the corresponding irreducible water saturation is more accurate. The experimental results of 77 samples in the research area showed that the irreducible water saturation has a good correlation with the median pore throat radius which has a good correlation with the porosity. The irreducible water saturation is consistent with the nuclear magnetic experiment results. Therefore, a new method to determine the irreducible water saturation based on logging data is established. The application results of this method in tight sandstone reservoirs in the Keshen area show that the fluid types identified by the relationship between the calculated irreducible water saturation and total water saturation are consistent with the actual test results, which confirms the accuracy and feasibility of this method. This method solves the problem of irreducible water saturation evaluation in low-porosity and ultra-low-permeability sandstone reservoirs. In the field or other situations where core testing is lacking, accurate irreducible water saturation can be obtained based on only porosity. It also lays a foundation for further improving the prediction accuracy of fluid properties, which has broad application prospects.

In addition, an example is presented to show the application of our main results.
Complexity trade-offs and equi-complexity in natural languages: a meta-analysis

Published: October 2022

AbstractIn linguistics, there is little consensus on how to define, measure, and compare complexity across languages. We propose to take the diversity of viewpoints as a given, and to capture the complexity of a language by a vector of measurements, rather than a single value. We then assess the statistical support for two controversial hypotheses: the trade-off hypothesis and the equi-complexity hypothesis. We furnish meta-analyses of 28 complexity metrics applied to texts written in overall 80 typologically diverse languages. The trade-off hypothesis is partially supported, in the sense that around one third of the significant correlations between measures are negative. The equi-complexity hypothesis, on the other hand, is largely confirmed. While we find evidence for complexity differences in the domains of morphology and syntax, the overall complexity vectors of languages turn out virtually indistinguishable.

Published: October 2022

Abstract
Esophageal squamous cell carcinoma (ESCC) is an aggressive malignant tumor with a poor prognosis. The dysregulation of long non-coding RNAs (lncRNAs) is closely related to the tumorigenesis and progression of ESCC. However, the effects of lncRNA small nucleolar RNA host gene 3 (lncRNA SNHG3) in ESCC are still unclear. Therefore, a series of experiments methods, such as quantitative real-time polymerase chain reaction, function gain/loss experiments, western blots, and animal xenograft tumor model, were employed to explore the biological function and molecular mechanism of SNHG3 in ESCC. As results, we first reported that SNHG3 was significantly up-regulated in ESCC tissues and cells. SNHG3 knockdown obviously inhibited cell proliferation, migration, invasion, and promoted apoptosis. Mechanism analysis revealed that SNHG3 sponged miR-151a-3p to regulate PFN2. Inhibition of miR-151a-3p and overexpression of PFN2 attenuated the positive effect of SNHG3 knockdown on suppressing tumor progression. Furthermore, the anti-tumor effects of SNHG3 knockdown were also observed in vivo. In summary, our results indicated that SNHG3 knockdown suppressed tumor development via the miR-151a-3p/PFN2 axis, and targeting SNHG3 may provide a new opportunity for ESCC patients.

Authors: Değirmenci Züleyha 
Published: October 2022

Abstract
For the sustainability of the world, it is very important to use environmentally friendly products for cleaning textile products. Boron-added detergents, which are in the category of detergents used for this purpose, have also started to become popular. On the other hand, the cleanliness of the detergent and its effect on the quality of the product are equally important for the user. In this study, the effects of boron-added detergent on both stain removal and fabric performance were investigated. The research was conducted by comparing it with popular detergents preferred by users. Sample knitted fabric made of 100 % cotton was used for the analysis. The sample fabric was stained with tea, coffee, mud, and ketchup under favorable conditions and washed repeatedly in a household washing machine identical to the literature. After washing, the level of removal of stains, performance losses, and dimensional change were examined. The performance of boron-added detergent was compared with other detergents, and it was tried to analyze whether this detergent was usable. During the study, a household front-loading washing machine was used for washing, Truburst bursting strength tester was used to detect the strength of samples, an SDL Atlas stability template templer and ruler were used to evaluate the dimensional stability, and grayscale was used to compare stain removal. For analyzing the test results, graphs and scales were used. One-way ANOVA test was applied via the Design Expert 13.0 package program used for the interpretation of the test results.
Miniature C(T) Specimens—Pinhole Eccentricity and the Effect of Crack Opening Displacement Measurement Location
Authors: Sirkiä L. , Kuutti J. , Virkkunen I. 
Published: October 2022

AbstractThis paper focuses on the quality criteria for miniature compact tension (C(T)) specimens. The continuously diminishing volume of reference materials for fracture toughness surveillance testing encourages research on the usability of miniature-sized test specimens, and consequently, it is of great interest in the nuclear power plant field. Sufficient quality criteria and applicability are investigated experimentally and numerically by varying the pinhole locations to investigate the importance of the eccentricity of pinholes and its effect on measurement results. Additionally, the effect of measuring the crack opening displacement (CMOD) from the load line versus the front face and the effect of side grooving are studied with experimental arrangements. The results show that neither the eccentricity of pinholes within the studied offset values nor the location of the CMOD gauge imposes limits on the applicability of miniature C(T) specimens. With eccentric pinholes or any CMOD gauge placement, the fracture toughness results are valid.

Os bivalves constituem estoques naturais de recursos renováveis que dependem de um ecossistema em equilíbrio. Alimentam-se principalmente de microrganismos presentes na água, como são organismos filtradores, concentram em seus tecidos, sobretudo nas brânquias, materiais de diversas naturezas, desde substâncias químicas a contaminantes, por esse motivo são considerados bioindicadores da qualidade da água. Durante o período de novembro de 2020 a junho de 2021, 103 ostras foram coletadas manualmente, em ambiente natural, na Ponta da Barra, Lagoa do Noca, na cidade de Laguna, litoral sul do estado de Santa Catarina, Brasil. As brânquias foram retiradas, submetidas em meios de cultura para crescimento e identificação de microrganismos. Treze espécies de bactérias indicadoras da presença de coliformes foram identificadas em 73,79% (76/103) das amostras. As mais prevalentes foram Escherichia coli, Citrobacter koseri, Klebsiella pneumoniae e Proteus mirabilis, com percentuais de 21,05%, 13,16%, 13,16% e 11,84%, respectivamente. A presença desses microrganismos em ambientes aquáticos pode levar ao aparecimento de doenças transmitidas de forma direta, pela ingestão dos agentes patogênicos, ou indireta, pela ingestão de toxinas bacterianas. Dessa forma, levam perigos às espécies de níveis tróficos superiores, como também ao ser humano, representando um grave risco à saúde pública.

Crocodilians are considered as good indicators of ecosystem health since environmental conditions will influence them at individual (body condition and health parameters) and populational levels (population dynamics and behavior). Despite that, there are few attempts to use crocodilians as bioindicators and the lack of baseline health parameters is an impediment to this. Here, hematological and biochemical reference values for free-ranging Caiman latirostris (broad-snouted caiman) in the Brazilian Atlantic Forest, one of the most threatened biomes in the world, are proposed. Young caiman are more sensitive to environmental variations, besides being more abundant and more easily captured, when compared to adults, which facilitates their use as bioindicators. Furthermore, problems that affect young caimans may represent future population problems. The data obtained is an important tool in assessing the health of free-living populations, contributing to the use of C. latirostris as a bioindicator of health in the Atlantic Forest aquatic ecosystem.

Two structurally connected brain regions are more likely to interact, with the lengths of the structural bundles, their widths, myelination, and the topology of the structural connectome influencing the timing of the interactions. We introduce anin vivoapproach for measuring functional delays across the whole brain in humans (of either sex) using magneto/electroencephalography (MEG/EEG) and integrating them with the structural bundles. The resulting topochronic map of the functional delays/velocities shows that larger bundles have faster velocities. We estimated the topochronic map in multiple sclerosis patients, who have damaged myelin sheaths, and controls, demonstrating greater delays in patients across the network and that structurally lesioned tracts were slowed down more than unaffected ones. We provide a novel framework for estimating functional transmission delaysin vivoat the single-subject and single-tract level.SIGNIFICANCE STATEMENTThis article provides a straightforward way to estimate patient-specific delays and conduction velocities in the CNS, at the individual level, in healthy and diseased subjects. To do so, it uses a principled way to merge magnetoencephalography (MEG)/electroencephalography (EEG) and tractography.

Introducción: Spiraxidae es la familia de gasterópodos terrestres más diversa de México con una distribución principalmente neotropical. Sin embargo, la influencia de las condiciones ambientales de esta región en su distribución aún es poco conocida. Objetivo: Determinar las afinidades zoogeográficas y la influencia de factores ambientales en la distribución de Spiraxidae en México. Métodos: Compilamos registros de distribución de museos y usamos modelos para establecer áreas con composición de especies, concentración de especies, afinidades y relaciones con variables ambientales similares. Resultados: Encontramos 231 especies y subespecies, 96 en el estado de Veracruz y 74 en la Sierra Madre Oriental. La principal afinidad zoogeográfica fue neotropical. El bosque mesófilo de montaña tuvo la mayor cantidad de especies y subespecies (93). Tres de los grupos zonales tienen una composición particular de especies y el 67 % de las especies son especialistas de hábitat. La presencia de especies sigue un gradiente ambiental, con la cubierta de árboles de hoja perenne de hoja ancha y la precipitación media anual como variables determinantes. Las especies del norte tuvieron mayor tolerancia a la aridez y menor cobertura de hojas. Conclusiones: Spiraxidae tiene su mayor diversidad en los estados del Sur de México; sin embargo, la zona nororiental tiene más registros de especies. Estos caracoles se encuentran principalmente en bosques mesófilos de montaña y bosques tropicales siempre verdes. Las especies del norte de México tuvieron una mayor tolerancia a los sitios con poca lluvia y menos cobertura de árboles de hoja perenne de hoja ancha que las especies del sur.

Published: October 2022

Introduction: The study of herbivory is fundamental in ecology and includes how plants invest in strategies and mechanisms to reduce herbivore damage. However, there is still a lack of information about how the environment, plant density, and functional traits influence herbivory in aquatic ecosystems. Objective: To assess if there is a relationship between herbivory, environmental variables, and plant traits two species of Montrichardia, a neotropical aquatic plant. Methods: In September 2018, we studied 78 specimens of Montrichardia arborescens and 18 of Montrichardia linifera, in 18 sites in Melgaço, Pará, Brazil. On each site, we measured water depth, distance to the margin, and plant density. From plants, we measured plant height and leaf thickness, and photographed the leaves to calculate the specific leaf area and percentage herbivory. To identify anatomical structures, we collected fully expanded leaves from three individuals per quadrat. Results: For M. arborescens, plants with thicker leaves and higher specific leaf area have less herbivore damage. For M. linifera, plants from deeper sites and with thicker leaves had more herbivore damage, while plants that grew farther from the margin had less damage. We found anatomical structures related to defense, such as idioblast cells with phenolic compounds, and cells with solid inclusions that can contribute to avoiding severe damage. Conclusions: Herbivory in these Montrichardia species canbe explained by a combination of plant and environmental traits (patch isolation and water depth). The main plant traits are leaf thickness and area, but chemical compounds and solid inclusions also help Montrichardia to sustain less damage than other macrophytes.

Published: October 2022

Introducción: El bivalvo Anadara tuberculosa es un recurso pesquero y económico importante en el Pacífico Este Tropical. La proporción sexual varia a lo largo de su área de distribución, con casos de aparición de hermafroditismo, ocasional para algunas poblaciones, normal en otras. Estas características podrían ser una respuesta a presiones antropogénicas y ambientales. Objetivo: Evaluar la proporción sexual y el hermafroditismo en la especie en el Pacífico de Panamá. Métodos: Se analizó información reproductiva de A. tuberculosa generada entre 1994 y 2020 para el Golfo de Montijo, así como datos de 2017 para el manglar de David. Se aplicaron procedimientos macroscópicos, contrastados con histológicos y se generó un factor de corrección para ajustar la proporción sexual macroscópica, debido al efecto, sobre la proporción sexual, que ocasiona los organismos indeterminados. Resultados: Para el Golfo de Montijo, la histología indicó una proporción sexual hembra a macho de 1:1 hasta 3.2:1, entre 1994 y 2017, mientras que la macroscopía varió de 1.9:1 a 5.1:1 entre 2004 y 2020. Para el manglar de David, la histología indicó una proporción sexual de 3.7:1, y de 7.9:1 por macroscopía en el 2017. En ambas localidades, especímenes más grandes mostraron mayor variación en la proporción sexual, pese a la técnica implementada, así como hermafroditismo protándrico no casual en el 2017. Conclusiones: La aparición del hermafroditismo protándrico y los cambios en la proporción sexual indican que la población de A. tuberculosa, en ambas localidades, está respondiendo a presiones antropogénicas y ambientales.

AbstractThe objectives of the study were to estimate the prevalence of anti-Toxoplasma gondii antibodies in free-range chickens in Aguascalientes, Mexico, its association with certain risk factors, and the frequency of parasite DNA in the heart. Eighty-one small rural family farms were included, and blood and heart samples were taken from 150 clinically healthy, adult, free-range chickens. Serum samples were processed by indirect immunofluorescence antibody test considering a dilution of 1:16 as a positive reaction, while the DNA detection was done by PCR. The correlation between the presence of antibodies and the potential risk factors was estimated with logistic regression. The overall seroprevalence in the examined populations was 67%, with a range from 33% to 100% among municipalities, and 78% of the farms having at least one seropositive bird. The PCR test identified the presence of parasite DNA for one case only. Among the variables, the presence of cats and the presence of other animal species on the farm were the ones that had the highest values, while the presence of feral cats and the presence of noxious fauna were also identified as potential risk factors. The results indicate high soil contamination by T. gondii oocysts, which implies the active role of cats living on the farms.
El principio de reciprocidad y la globalización del derecho desde la perspectiva de la regla de oro
Authors: Liu Shing-I 
Published: October 2022

En el pasado vivíamos en una única tierra, pero en muy diferentes mundos. Hoy vivimos en un único mundo profundamente interdependiente, pero en muchos importantes aspectos antes éramos independientes unos de otros. Al mismo tiempo, llegamos al único mundo moderno desde muy diferentes tradiciones. Todavía tenemos ideas en las que impera un gran desacuerdo en materias tan importantes como las organizaciones políticas de nuestros Estados nacionales, la universalidad de los derechos humanos, las relaciones entre mujeres y hombres, la libertad de las minorías. Esas diferencias no son sólo entre culturas. Por consiguiente, es de gran importancia llevar a cabo un cuidadoso estudio del fundamento jurídico de la estela de la globalización y de la aparición de bloques. La reciprocidad es un principio fundamental presente en fas religiones y culturas más importantes. Se aduce como fundamento más importante para los derechos positivos y el concepto moderno de derechos humanos. La regla de oro se fundamenta en el principio de reciprocidad y es la forma moral básica de la humanidad, defendida por diversas culturas y por todas las religiones del mundo. Con conocimiento, imaginación y la regla de oro podemos llegar lejos en nuestro pensamiento moral. La regla de oro ha de entenderse como un principio de consistencia. La regla de oro no nos dice qué acto específico se ha de hacer. No substituye a normas morales cotidianas. No es una guía infalible sobre qué acciones son correctas o equivocadas; no da todas las respuestas. Solamente prescribe consistencia, que no llevemos a cabo acciones (hacia otros) que carezcan de armonía en relación con nuestros deseos (hacia una acción invertida de la situación).
Es importante advertir que por el hecho de que el principio esté fundamentado en la característica genérica de acción tiene una cierta clase de necesidad material. Se recordará que algunos de los argumentos justificatorios para los derechos anteriormente examinados son erróneos porque ellos no satisfacen la condición de que puedan ser aceptados por toda persona racional como una cuestión de necesidad racional.
