Authors: Almutairi Shahah 
Published: August 2024

Abstract
Global in time weak solution to a regularized periodic three-dimensional Boussinesq system is proved to exist in energy spaces. This solution depends continuously on the initial data. In particular, it is unique. The main novelty is the global in time aspect of this solution. The proofs use the coupling between the temperature and the velocity of the fluid, energy methods, and compactness argument.
Complexiton and interaction solutions to a specific form of extended Calogero–Bogoyavlenskii–Schiff equation via its bilinear form
Authors: Khareng Sukri , Ünsal Ömer 
Published: August 2024

Abstract
In this article, we are focusing on an extended Calogero–Bogoyavlenskii–Schiff equation which was altered originally from a new generalized fourth-order nonlinear differential equation that obtained from Calogero–Bogoyavlenskii–Schiff equation. We apply simplified Hirota method, which is an exclusive form of the direct Hirota bilinear method, to a specific form of a new generalized fourth-order nonlinear differential equation. The key point in applicability of referred method is attainability proper forms of dispersion relations and phase shifts. Through this procedure, we present different types of solutions for three different cases. We also give constrictions for each solution type in this work so that readers can distinguish differences among types of solutions. In addition, we introduce some graphical representations for obtained solutions, even for existence of complexiton and interaction solutions.

Published: August 2024

Abstract

Objectives
Atenolol is a commonly used beta bloscker in non-pregnant women. Many providers are hesitant in prescribing atenolol in pregnancy because of a possible association with poor fetal growth. We aimed to assess the association between atenolol and the occurrence of small for gestational age neonates compared to other beta blockers, as described in the existing literature.

Methods
We used the meta-analytic method to generate a forest plot for risk ratios (RR) of small for gestational age in patients who used atenolol vs. other beta blockers. Statistical heterogeneity was assessed with the I2 statistic.

Results
Two studies were included, with a resultant RR of 1.94 [95 % confidence interval (CI) 1.60; 2.35]. A study by Duan et al. in 2018 noted the following rate of small for gestational age for each beta blocker use: 112/638 atenolol, 590/3,357 labetalol, 35/324 metoprolol, and 50/489 propranolol. A study by Tanaka et al. in 2016 noted the following rate of small for gestational age: 8/22 for propranolol, 2/12 for metoprolol, 2/6 for atenolol, 0/5 for bisoprolol. Heterogeneity (I2) was 0 %.

Conclusions
Our results suggested an elevated risk of small for gestational age associated with atenolol use in comparison to other beta blockers, specifically labetalol, propranolol, bisoprolol, and metoprolol.

Published: August 2024

Abstract
Fractional partial differential equations (FPDEs) have gained significant attention in various scientific and engineering fields due to their ability to describe complex phenomena with memory and long-range interactions. Solving FPDEs analytically can be challenging, leading to a growing need for efficient numerical methods. This review article presents the recent analytical and numerical methods for solving FPDEs, where the fractional derivatives are assumed in Riemann-Liouville’s sense, Caputo’s sense, Atangana-Baleanu’s sense, and others. The primary objective of this study is to provide an overview of numerical techniques commonly used for FPDEs, focusing on appropriate choices of fractional derivatives and initial conditions. This article also briefly illustrates some FPDEs with exact solutions. It highlights various approaches utilized for solving these equations analytically and numerically, considering different fractional derivative concepts. The presented methods aim to expand the scope of analytical and numerical solutions available for time-FPDEs and improve the accuracy and efficiency of the techniques employed.

Abstract
Yardstick competition as a tool to set the prices of regional natural monopolies is now an established tool. After 30 years of application to the water industry in England and Wales, this article takes a critical look at how yardstick competition has been implemented in the latest Price Review 2019 (PR19). It proposes reforms to ensure that in the next Price Review 2024 (PR24) and/or beyond the efficiency challenges are appropriately set and the degree of information at the regulator’s disposal is maximised.
Hannah Arendt: a importância da sociabilidade em um estado democrático de direito
Authors: PADILHA ROSSANA BATISTA , Lemos Martins Caroline 
Published: August 2024

: Para que se possa abordar a sociabilidade em Hannah Arendt (1906-1975), é importante mencionar a importância que a autora confere, em suas obras, à necessidade de organização dos grupos humanos por meio de regras, assim como de que essas regras sejam seguidas para a preservação da vida em conjunto. Segundo a autora, a política é a maneira humana de convívio entre os homens e mulheres por meio do gerenciamento de questões emergentes, sem o uso de qualquer coação. Ainda, para ela, a igualdade não se origina da linhagem, do status social, mas da igualdade no sentido de poder agir em conjunto. Assim o indivíduo tem um importante papel a ser exercido na esfera política, enquanto cidadão. Nesse contexto, é preciso que haja um “espaço público”, bem como, que os cidadãos tenham a liberdade para expressar-se, podendo contestar, discutir as ideias e ideais, sem utilizar-se de qualquer tipo de violência, buscando, por meio dessa elaboração conjunta, adquirir outros direitos, por exemplo, à saúde, à educação, à moradia, ao emprego. A existência da possibilidade de ver e ser visto, discordar e poder expor isso, para Arendt, apenas ocorre em uma convivência política, na pluralidade, buscando a elaboração de regras para a organização do grupo em que vivem e pelo qual se sentirão partícipes e responsáveis. Ou seja, é uma atitude que ocorre em um espaço público de encontro de iguais, enquanto cidadãos, diferentes, enquanto seres únicos por nascimento, a fim de conseguir, mesmo que momentaneamente, a garantia de paz no convívio das singularidades. O presente texto visa a destacar a importância da necessidade dos laços de sociabilidade em um Estado Democrático de Direito, a partir da obra Origens do Totalitarismo, no qual Arendt descreve o Regime Totalitário vivenciado por ela, bem como, a ruptura dos laços de sociabilidade, fatos passíveis de discussão para pensar a situação política, não somente do Brasil como também de outros estados considerados democráticos.

Published: August 2024

Summary The equine gastric ulcer syndrome (EGUS) involves a complex of diseases associated with ulceration of the esophageal, stomach and duodenum mucosa of horses. EGUS occurs frequently due to multiple and overlapping risk factors (activity, food management, anti-inflammatory therapies, among others) and anatomo-physiological peculiarities of horses. The combination of therapeutic strategies and management and environmental shifts are important in both the preventive and the curative approach to this syndrome. However, further studies on the epidemiological and clinical aspects of EGUS and low-cost therapeutic alternatives are required. Key words: glandular and nonglandular mucosa, gastroscopy, horse, hydrochloric acid, stomach, treatment.Resumen El síndrome de úlcera gástrica equina (EGUS) implica un complejo de enfermedades asociadas con ulceración de la mucosa esofágica, gástrica y duodenal en animales con diferente edad. EGUS es altamente frecuente por la naturaleza multifactorial de los factores de riesgos (tipo de actividad, manejo alimentario, terapias anti-inflamatorias, entre otros) y particularidades anatomo-fisiológicas de estos animales que son sometidos excesivamente en los diferentes sistemas de explotación. La combinación de estrategias terapéuticas, de manejo y de adecuación de ambiente son de importancia en las conductas preventivas y curativas de este síndrome. Sin embargo se requiere más estudios de prevalencia y de caracterización de los factores predisponentes de EGUS; así como también, más investigación para generar alternativas terapéuticas de bajo costo.

Arte y Geografías del Compromiso. El Arte Transformador como Problema Situado.
Authors: Macaya Albert 
Published: August 2024

Las artes con vocación transformadora, con voluntad de compromiso social, son hoy objeto de ricos y complejos debates. En este texto repasamos tres ideas clave sobre su vigencia: su capacidad de crear agenciamiento colectivo e incidir en audiencias amplias, la popularización de algunas de sus formas a través de la telefonía móvil y las redes sociales, y su capacidad de incidir en contextos específicos a través de la participación activa de una determinada comunidad. Para pensar dialécticamente estas tres ideas, las plantearemos como “tesis” con sus respectivas “antítesis”, esbozando algunas de las críticas o cuestionamientos de las que esas posiciones han sido objeto. Sin embargo, propondremos argumentos para revisar la universalidad de tales cuestionamientos. Basándonos en algunos destacados ejemplos del arte comprometido latinoamericano, concluimos que las posibilidades transformadoras de las artes son esencialmente un problema situado, que debe ser examinado en relación a un contexto específico para poder valorar su sentido y alcance.

Published: August 2024

Global warming is the increase in temperature in the atmosphere, sea and land. The increase in carbon or greenhouse gases is one of the causes of global warming. One solution to reduce the presence of greenhouse gases is to increase carbon stock. Beach is home to the richest ecosystems in the world and many components of the vegetation that store large amounts of carbon stock. Carbon compounds in the atmosphere are absorbed and metabolized. The metabolic products are stored in tree biomass. One of the trees that can be relied on as a stock carbon is those located at Cemara Sewu Beach, Cilacap. Cemara Sewu Beach is one of the beach that has a relatively large amount of stored carbon potential. The purpose of this study was to determine the carbon stored in several types of trees at Cemara Sewu Beach.
The method used in this study is a survey method with purposive sampling using without destroying. The sampling of Australian pine tree stands is grouped into certain diameter class. The coastal area was made into three research stations and each study was made into 5 replicated plots measuring 20 m x 20 m and placed on a transect line with a distance of 5 meters each. All of the Australian pine were plotted as samples. The independent variable in this study was the diameter class of Australian pine, while the dependent variable was carbon stock. The main parameters observed were tree density, trunk diameter and the number of individuals for each tree species were calculated. The data obtained were analyzed using Analysis of Variance (ANOVA) followed by the Least Significant Difference (LSD) test with an error rate of 5%.
The results of the research on the diameter class of Australian pine greatly affect the presence of biomass and carbon stock. The results obtained that carbon stocks in diameter class 15-20 store 74,914 ton.ha-1, diameter class 21-25 as many as 164,599 ton.ha-1, diameter class 26-30 as many as 270,372 ton.ha-1, diameter class 31-35 store stocks carbon 462,478 ton.ha- 1 and in the diameter class 36-40 store as much as 462,478 ton.ha-1. The larger the class diameter, the greater the carbon stock produced. The diameter class of Australian pine stands has a relationship between biomass and carbon stock, and has an exponential relationship.

Coal mining in Indonesia generally carried out with an open system that has an impact on environmental damage. One strategy to control these problems by using Arbuscular Mycorrhizal Fungi (AMF). This study aimed to determine the effect of AMF inoculum on the growth of maize plants and to determine the optimum dose of AMF on maize plant growth using ex-mining soil as a planting medium.This research used an experimental method with a completely randomized design (CRD) with 4 doses of AMF (0, 100, 150, 200 g) by using ex-coal mined soil medium which consisted of three repetition. The independent variable was the dose of AMF and the dependent variable was the ability of AMF to infect roots. The main parameter observed was the degree of root infection, while the supporting parameters were plant dry weight, number of leaves and height of corn plants. Data were analyzed using Variance Analysis (ANOVA) test with a standard error of 5% and tested with Honestly Significant Different (HSD). The results showed that the AMF dose treatment on the ex-coal mined land had an effect on the growth of corn plants at 42 days after planting. AMF has a positive effect on the growth of corn plants. The dose of 100 g/polybag is an effective dose to increase the growth of corn plants on ex-coal mining soil. The dose of 200 g/polybag gave the best results on plant height, number of leaves and dry weight of corn plants.
