A Discontinuous Galerkin and Semismooth Newton Approach for the Numerical Solution of Bingham Flow with Variable Density
Authors: González-Andrade Sergio , Méndez Silva Paul E. 
Published: August 2023

Abstract
This paper is devoted to the study of Bingham flow with variable density.
We propose a local bi-viscosity regularization of the stress tensor based on a Huber smoothing step.
Next, our computational approach is based on a second-order, divergence-conforming discretization of the Huber regularized Bingham constitutive equations, coupled with a discontinuous Galerkin scheme for the mass density.
We take advantage of the properties of divergence-conforming and discontinuous Galerkin formulations to effectively incorporate upwind discretizations, thereby ensuring the stability of the formulation.
The stability of the continuous problem and the fully discrete scheme are analyzed.
Further, a semismooth Newton method is proposed for solving the obtained fully discretized system of equations at each time step.
Finally, several numerical examples that illustrate the main features of the problem and the properties of the numerical scheme are presented.
On split generalized equilibrium problem with multiple output sets and common fixed points problem
Authors: Godwin Emeka C. , Mewomo Oluwatosin T. , Alakoya Timilehin O. 
Published: August 2023

Abstract
In this article, we introduce and study the notion of split generalized equilibrium problem with multiple output sets (SGEPMOS). We propose a new iterative method that employs viscosity approximation technique for approximating the common solution of the SGEPMOS and common fixed point problem for an infinite family of multivalued demicontractive mappings in real Hilbert spaces. Under mild conditions, we prove a strong convergence theorem for the proposed method. Our method uses self-adaptive step size that does not require prior knowledge of the operator norm. The results presented in this article unify, complement, and extend several existing recent results in the literature.
Synthesis and characterization of proton-conducting membranes based on bacterial cellulose and human nail keratin
Authors: Gustian Irfan , Simalango Anastasia , Triawan Deni Agus , Hadi Putranto Agus Martono , Asdim  
Published: August 2023

Abstract
In this work, proton-conducting membranes have been prepared by entrapping human nail keratin in bacterial cellulose at different mass ratios. Bacterial cellulose was obtained by fermenting coconut water with the Acetobacter xylinum bacterium, and keratin was obtained from human nails. The membrane is produced by the blending and heating process at a temperature of 40°C. FTIR spectroscopy showed the interaction between bacterial cellulose and human nail keratin at a peak area of 3,000–2,000 cm−1. The X-ray diffraction analysis has confirmed the effect of keratin mass on the diffractogram pattern of the membranes. The maximum proton conductivity has been measured as 4.572 × 10−5 S·cm−1 at 25°C and produces a degree of swelling of 32.50% for a mass ratio of bacterial cellulose/human nail keratin 4:1.
Modernization of Chinese Film: Nationality, Periodicity, and Current Issues
Authors: Wang Yichuan 
Published: August 2023

Abstract
The nationality of modernization of Chinese film focuses on the concept of yingxi (影戏, the name for film in Chinese early years), family ethic, classical intellectual traditions, legendary stories, and “lingering favor” (yuwei 余味). The periodicity of modernization of Chinese film can be divided into three periods: the modernization of Chinese film phase I, the modernization of Chinese film phase II, and the modernization of Chinese film phase III, respectively representing how the Chinese nation has stood up, grown prosperous, and become strong. The current issues for modernization of Chinese film lies in expressing the five dimensions of the Chinese path to modernization, and the ongoing advancement of the modernization of Chinese film III. Chinese film studies should also seize this new opportunity to reexamine itself.

The impedance is a fundamental electrical property of brain tissue, playing a crucial role in shaping the characteristics of local field potentials, the extent of ephaptic coupling, and the volume of tissue activated by externally applied electrical brain stimulation. We tracked brain impedance, sleep–wake behavioral state, and epileptiform activity in five people with epilepsy living in their natural environment using an investigational device. The study identified impedance oscillations that span hours to weeks in the amygdala, hippocampus, and anterior nucleus thalamus. The impedance in these limbic brain regions exhibit multiscale cycles with ultradian (∼1.5–1.7 h), circadian (∼21.6–26.4 h), and infradian (∼20–33 d) periods. The ultradian and circadian period cycles are driven by sleep–wake state transitions between wakefulness, nonrapid eye movement (NREM) sleep, and rapid eye movement (REM) sleep. Limbic brain tissue impedance reaches a minimum value in NREM sleep, intermediate values in REM sleep, and rises through the day during wakefulness, reaching a maximum in the early evening before sleep onset. Infradian (∼20–33 d) impedance cycles were not associated with a distinct behavioral correlate. Brain tissue impedance is known to strongly depend on the extracellular space (ECS) volume, and the findings reported here are consistent with sleep–wake–dependent ECS volume changes recently observed in the rodent cortex related to the brain glymphatic system. We hypothesize that human limbic brain ECS changes during sleep–wake state transitions underlie the observed multiscale impedance cycles. Impedance is a simple electrophysiological biomarker that could prove useful for tracking ECS dynamics in human health, disease, and therapy.SIGNIFICANCE STATEMENTThe electrical impedance in limbic brain structures (amygdala, hippocampus, anterior nucleus thalamus) is shown to exhibit oscillations over multiple timescales. We observe that impedance oscillations with ultradian and circadian periodicities are associated with transitions between wakefulness, NREM, and REM sleep states. There are also impedance oscillations spanning multiple weeks that do not have a clear behavioral correlate and whose origin remains unclear. These multiscale impedance oscillations will have an impact on extracellular ionic currents that give rise to local field potentials, ephaptic coupling, and the tissue activated by electrical brain stimulation. The approach for measuring tissue impedance using perturbational electrical currents is an established engineering technique that may be useful for tracking ECS volume.

La necesidad colectiva de inclusión y de paridad de la mujer en la constituyente Chilena del 2022
Authors: Pérez Portillo Soraya 
Published: August 2023

Las necesidades colectivas muestran realidades sociales que se deben superar, para lo cual, desde la Organización de Naciones Unidas se trabaja en la Agenda 2030, a fin de alcanzar Objetivos y Metas que reduzcan estos niveles en especial sobre en la lucha contra el empobrecimiento ODS 1 y la igualdad de género ODS 5. Estas necesidades tienen su contexto en América Latina, igualmente enfocada con los Objetivos mundiales, exigiendo a los Estados una actitud proactiva en la materialización de la igualdad. Los procesos constituyentes latinoamericanos aperturistas e incluyentes reflejan en sus propuestas y nuevos marcos constitucionales, la constitucionalización de estas necesidades plasmadas en principios fundantes y en derechos de distinta generación, los que, son justiciables. La paridad Política en específico, en el Proceso Constituyente de Chile, que se manifestó en la integración de los y las convencionales, en la Convención Constituyente, hito en el constitucionalismo mundial, que buscaba a través de un encuentro político amplio, generar un nuevo horizonte, incluyente hacia la mujer y en el reconocimiento de los pueblos indígenas ancestrales que habitan el territorio chileno y en el pluralismo jurídico incluyente, fue rechazado por el pueblo en consulta, plebiscito de salida. La propuesta de una nueva Constitución Política, sin embargo, fue positiva, en explorar nuevos planteamientos constitucionales, que seguramente se retomarán en un nuevo itinerario constituyente.

The purpose of this study is to compare the efficacy of oral Mifepristone with the efficacy of intracervical Foley catheterisation for induction of labour in term pregnancy. The primary outcome of this study is to compare both methods of induction of labour in terms of induction to delivery interval and the secondary outcome is to compare the two methods in terms of route of delivery, indications of caesarean section and the neonatal outcomes. This study is a randomized control trial conducted from May 2022 to December 2022 in Department of Obstetrics and Gynecology, SSG Hospital, Baroda Medical College. 180 term pregnant patients were enrolled in this study based on a pre-established criteria. Patients were randomised into group A and B. Group A included patients who were given Tablet Mifepristone 200 mg PO followed by per vaginum Tablet Misoprostol and Group B included patients who underwent intracervical Foleys catheterisation followed by placement of per vaginum Tablet Misoprostol. The study concluded that there was significantly decreased induction-delivery interval in women induced with intracervical Foleys catheterisation (Group B) as compared to those given oral Tablet Mifepristone (Group A). There was no significant difference between the two groups in terms of the route of delivery, rate of C Sections and neonatal outcomes.Mifepristone is effective for inducing indicated term pregnancies, despite no decrease in induction delivery interval. Incidence of fetal distress with oral Mifepristone is comparable to intracervical foley's catheterization. Further research is needed to assess tachysystole/hyperstimulation and fetal distress caused by Mifepristone.
Study of institute of medical sciences, BHU and Sir Sunder Lal Hospital staff regarding their attitudes and experiences of domestic violence
Authors: Pandey Uma , Narayan Aditi , Lindow S W 
Published: August 2023

: Domestic violence is a social evil prevalent across all cultures and societies. It refers to any form of physical or mental abuse suffered by a person from a relative or member of their domestic circle. The majority of the world is patriarchal and women are most affected. The present study was done to evaluate the attitudes and experiences of domestic violence amongst staff of SSH and IMS. A total of 392 staff were questioned regarding their attitudes and experiences of Domestic Violence victims. The study was a cross observational study and questionnaires were distributed via Google Forms and were filled anonymously. The responses collected were categorized on the basis of the student and qualified staff members of SSH and IMS. The data obtained was subjected to statistical analysis using SPSS software.: Qualified healthcare professionals (53%) had more exposure to domestic violence victims than students (28%) and were aware (51%) that inquiring about DV was essential in their job. However, they were more concerned (33%) about potential impacts on patient relationships than students (32%). Both groups preferred seeking help from friends/family (48%) over the police (28%) for DV victims. Students were more proactive in reporting DV to the police. More qualified professionals (44%) believed government efforts to address DV were inadequate, while students (60%) saw room for improvement. COVID-19 worsened DV according to 61% of students and 42% of professionals. Both groups acknowledged DV inquiry as part of their job and supported hospital-based help, with students (35%) favoring dedicated services for IPV victims more than professionals (29%). Both groups lacked sufficient DV training in their curriculum (42%).: Domestic violence persists as a social menace, often seen as a private matter despite available government and non-government efforts. The COVID-19 pandemic has exacerbated the situation for victims. Hospital support and healthcare professionals' training are lacking. Our study assesses the impact of DV training, urging authorities to address this critical issue.
