Thin-shell Tidal Dynamics of Ocean Worlds
Authors: Rovira-Navarro Marc , Matsuyama Isamu , Hay Hamish C. F. C 
Published: February 2023

Abstract
Several solar system moons harbor subsurface water oceans; extreme internal heating or solar irradiation can form magma oceans in terrestrial bodies. Tidal forces drive ocean currents, producing tidal heating that affects the thermal−orbital evolution of these worlds. If the outermost layers (ocean and overlying shell) are thin, tidal dynamics can be described using thin-shell theory. Previous work assumed that the ocean and shell's thickness and density are uniform. We present a formulation of thin-shell dynamics that relaxes these assumptions and apply it to several cases of interest. The tidal response of unstratified oceans of constant thickness is given by surface gravity and Rossby waves, which can resonate with the tidal force. The oceans of the outer solar system are too thick for gravity wave resonances, but high-amplitude Rossby waves can be excited in moons with high orbital obliquity. We find that meridional ocean thickness variations hinder the excitation of Rossby waves, decreasing tidal dissipation and increasing the inclination damping timescale, which allows us to reconcile the present inclination of the Moon with the existence of a past long-lived magma ocean and to explain the inclination of Titan and Callisto without invoking a recent excitation. Stratified oceans can support internal gravity waves. We show that dissipation due to internal waves can exceed that resulting from surface gravity waves. For Enceladus, it can be close to the moon’s thermal output, even if the ocean is weakly stratified. Shear due to internal waves can result in Kelvin–Helmholtz instabilities and induce ocean mixing.

Published: February 2023

With the advent of new technologies, smart devices, and the evolution of ICT in education, the integration of new technologies into learning systems has been mandated and a new way of learning has been born. E-learning and m-learning provide learners with great opportunities anytime, anywhere without restrictions. A new generation of students has grown up with technology and can be easily identified through smart devices. We discuss the identity of e-learning and m-learning; conduct a survey analysis to measure student and teacher interest. The survey aims to promote e-learning and m-learning for the student and teacher community for adoption in Moroccan higher education.
Qualitative and quantitative methods are supported. The results are analyzed at the end of this paper, and conclusions and positions are presented.

ABSTRACT.
In this prospective cohort study, we explored individual- and household-level risk factors associated with diarrheal diseases among 251 children younger than 5 years in slum areas of urban Dhaka, Bangladesh. During the 3-month study period, diarrhea surveillance was conducted monthly, and spot checks of the household compound were performed at baseline to assess the presence of feces (animal or human) in the household compound and in cooking and food storage areas, and to assess whether cooked food was covered and refrigerated. We also collected caregiver reports on child mouthing behaviors. Children living in households with feces within 10 steps of cooking and food storage areas (odds ratio [OR], 8.43; 95% CI, 1.01–70.18), those with visible feces found on the ground of the household compound (OR, 4.05; 95% CI, 1.24–13.22), and those in households found to keep cooked food uncovered and without refrigeration (OR, 6.16; 95% CI, 1.11–34.25) during spot checks had a significantly greater odds of diarrhea. There was no significant association between pediatric diarrhea and caregiver-reported child mouthing behaviors or presence of animals in the cooking area. These study findings demonstrate that presence of visible feces in the household compound and near cooking and food storage areas, and poor household food hygiene practices, were significant risk factors for diarrheal disease among young children in Dhaka, Bangladesh. Health communication programs are needed to target these exposure pathways to fecal pathogens.

Published: February 2023

The mass resettlement of Germans, among other Russian peoples, from Russia, Germany and other European countries and the formation of a diaspora on the territory of Turkestan began in the second half of the 19th century after its conquest by the Russian Empire. Having successfully adapted to the new lands, Germans, along with other peoples, took an active part in the political, cultural and economic life of Turkestan. This article is devoted to the representatives of the German diaspora who were directly involved in the economy of Turkestan. The goal is to analyze the economic activity of the Germans in Turkestan in the second half of the 19th – early 20th centuries. In this study, both general scientific and specialized methods are used, which allowed for a consistent analysis.
We have identified various areas of German entrepreneurship in the spheres of the economy of Turkestan. In particular, urban Germans were directly employed in the field of service personnel, in industrial, commercial and entrepreneurial activities; they acted both as independent merchants and as managers of firms. Rural peasants, German settlers, became one of the main driving forces of the agrarian development of the region. They became owners of farms, contributed to the development of agriculture, irrigation and animal husbandry. An analysis of the economic activities of the German diaspora in Turkestan showed that, despite their relatively small number in the region, they had a very noticeable impact on the socio-economic development of the region, which had a positive value for Turkestan. The article may be useful to scientific and practical workers, graduate students and all those who are interested in the history of the German diaspora and the development of the economy in the Turkestan period.

These factors are studied well in various parts of the world; however, these factors are understudied in Pakistan. This study aimed to find out the risk factors of pilonidal sinus among the patients diagnosed with pilonidal sinus.
Methodology: This descriptive cross-sectional study was conducted among one hundred and eight patients with pilonidal sinus at Benazir Bhutto Hospital Rawalpindi, for one year from January 2021 to January 2022. Ethical approval and informed consent were obtained before the start of study. Patients’ enrollment was done according to a developed inclusion and exclusion criteria. Convenient sampling technique was also applied for recruitment of participants. Data was collected through a self-designed questionnaire. Descriptive statistics were utilized for the data analysis. Data analysis was performed by SPSS version 25.0 (IBM Corp., Armonk, NY).

Purpose: Stroke incidence is high all over in the world. It has a list of specific warning signs and risk factors. Awareness of people about those warning signs and risk factors is low especially in third world countries. This study aimed to identify the awareness of people about the warning signs and risk factors of stroke.
Methodology: This descriptive cross-sectional study was performed in a tertiary care hospital, Rawalpindi, among one hundred for one year from June 2021 to June 2022. Ethical approval and informed consent were waived before the start of study. Patients’ selection was made via a well-defined inclusion and exclusion criteria. Convenient sampling technique was also used for enrollment of participants. Data was collected by using a self-designed questionnaire. Descriptive statistics were put into action for the data analysis. Data analysis was carried out by SPSS version 25.0 (IBM Corp., Armonk, NY).
Findings: The warning sign of the stroke about which most of the people were aware was sudden body weakness or numbness (74%) while warning sign about which people were least aware was sudden difficulty in seeing objects by one or both eyes (29%). The most common identified risk factor in people was hypertension (70%) for stroke while least common identified risk factor was family history of stroke (36%). In short, this study indicates people awareness about the warning signs and risk factors of stroke was not up to the mark in study population.
Recommendation: There is need to increase the awareness level of people about the warning signs and risk factors of the stroke. This could lead to timely and effective management of stroke and its prevention as well.
