AbstractReactive aluminum–nickel multilayer system shows exothermic energetic materials which act as a heat source for packaging and bonding of microsystems. The main challenge is controlling the self-propagation reaction velocity and temperature generated by thermal management through different thermal conductive substrate materials. The current work investigates the heat distribution of Al/Ni multilayer foils from different thermal conductive substrates which act as heat sink materials during the self-propagating reaction. A two-dimensional numerical model was developed to study thermal conductive heat loss and substrate thermal properties on the self-propagating reaction in Al/Ni multilayer foils. The self-propagating reaction was introduced on the surface of the foils by an electrical spark. Here we investigate the minimum critical thickness of Al/Ni multilayer foils which shows the self-propagation reaction on different substrates and verified from the two-dimensional numerical model. The outcomes of this investigation will facilitate the integration of Al/Ni multilayer foils on different substrates as intrinsic heat sources for different applications of micro/nanodevices.

The main idea of the investigation was to define testing parameters with the lowest influence of internal and external diffusion on catalytic activity in hydrodesulfurization of dibenzothiophene. Traditional experimental methods were used to determine the conditions for the influence of internal and external diffusion. Simultaneous change of a linear feedstock rate and a catalyst loading at constant weight hour space velocity were used to determine the process temperature (240–260 °C) at which the impact of external diffusion is minimal. Catalytic tests, including the variation of the catalyst fraction size, were carried out to define the conditions with the lowest influence of internal diffusion. It was found that when the catalyst with the fraction size of 0.1–0.25 mm was used, the fluctuation of sulfur conversion was the smallest. Besides, to validate experimental results, the calculations were performed with mass balance equations and expressions used for HDS modeling. The resulting data and catalytic experiments demonstrated that the lowest influence of internal and external diffusion is achieved at a temperature process less than 260 °C and a catalyst fraction of 0.1–0.25 mm.

Study purpose. The basic assumption of this development is that there is no Game Performance Assessment Instrument (GPAI) based on physical education (PE) learning outcome assessment, so researchers are trying to develop the instrument. The teacher has not used the GPAI instrument in assessing the PE learning outcomes for volleyball material. The purpose of the study was to develop a valid and reliable assessment of PE learning outcomes for volleyball based on GPAI.
Materials and methods. This type of research is research and development. The subjects used were PE learning expert lecturers and volleyball expert lecturers with a minimum qualification of 5 Doctoral degrees. The field test was conducted on 18 junior high school students. The instrument uses a questionnaire with a score of 1-4 with the terms “Very Appropriate (score 4)”, “Agreed (score 3)”, “Not Appropriate (score 2)”, and “Very Not Appropriate (score 1)”. The validity data analysis technique uses Aiken validity, and reliability tests are carried out using Intraclass Correlation Coefficients.
Results. Based on the results of the research and the results of the data analysis that has been carried out, it is concluded that the instrument for assessing the learning outcomes of PE on volleyball material in Junior High School based on GPAI that was developed is valid and reliable, with V Aiken ≥ 0.87. Furthermore, the reliability of the PE learning outcomes assessment instrument for volleyball material in GPAI-based junior high schools was 0.797 in the "High" category.
Conclusions. The researcher hopes that the resulting product in the form of an assessment of PE learning outcomes for volleyball material in junior high schools based on the GPAI can be a guide or reference for evaluating students on volleyball material.

ABSTRACT
On 12 January 2020, an eruption began on the shores of the Main Crater Lake (MCL) of Taal Volcano—a caldera system on the southern end of Luzon Island in the Philippines. Taal, one of the most active volcanoes in the Philippines, is located 30 km south of Manila—a major metropolitan area with a population of 13.5 million people. Eruptive activity intensified throughout the day on 12 January, producing prolific volcanic lightning, ashfall, and a sustained plume that reached 16–17 km altitude. The chronology of events was well documented by the Philippine Institute of Volcanology and Seismology and the Tokyo Volcanic Ash Advisory Center. The wealth of data collected during the eruption provides a unique opportunity to investigate how the combination of different remote sensing methods may complement local observations and monitoring. Remote systems tend to provide lower resolution data but are also less likely to be compromised by the eruptive activity, thus providing continuous records of eruptive processes. Here, we present a postevent analysis of the 12 January activity, including data from long-range lightning, infrasound, and seismic arrays located at distances up to several thousands of kilometers from the volcano. By combining these datasets, we distinguish five phases of activity and infer a major shift in eruption behavior around 12:00 on 12 January (UTC). The remote observations suggest that the most of the water within the MCL (∼42  million m3) was vaporized and incorporated into the volcanic plume within the first 12 hr of the eruption.

Published: April 2023

The relationship between physical activity, physical fitness, and academic performance has been widely studied internationally. However, reports of this relationship are contradictory, and its impact is still a matter of controversy. For that reason, the current research determined the correlation between these three variables in a group of 56 female and 48 male Colombian students with an average age of 14.08 ± 0.89 years. A quantitative, correlational, and cross-sectional study was carried out. The physical activity was evaluated using PAQ-A questionnaire. For physical fitness, six tests from the Euro fitness battery were used. The academic performance in Spanish, Math, Natural, and Social Sciences were obtained from the grades for the participants at the end of the academic year. Correlations were determined by multivariate multiple linear regression. The obtained results suggest that aerobic endurance test had effect in the studied variables, whereas the correlation of the other tested predictors did not show any meaningful statistical result. In fact, academic performance is not affected by the physical fitness of the students at the time course grades were measured.

Published: April 2023

Violations in the provision of medical care are detected by controlling the volume, timing, quality and conditions of medical care. The objective of the work is assessment of the activities of the round-the-clock hospital from the standpoint of the quality of medical care during the COVID-19 pandemic. Material and methods. A database of indicators reﬂecting the activity of round-the-clock hospital for four years, from 2017 to 2020 (Omsk) was formed. Analytical, statistical methods and the method of expert assessments were used to analyze the required indicators. Results. Evaluation of inpatient hospital activities during the COVID-19 pandemic compared to the “pre-pandemic” years showed a 1.9-fold and 2.9-fold decrease in the total number of quality examinations performed and the number of defects detected, respectively. The number of defects that were grounds for denial or reduction of payment for medical care found in the “before-COVID-19” years was 2.1 times higher than in 2020. In 2020, the weight of the share of those defects that directly reﬂect the quality of medical care increased signifcantly. The quantitative composition of the inpatient hospital staﬀ changed insignifcantly during the analyzed period – the number of physicians increased by only 5 % over four years, with no dynamics in the qualitative characteristics of the staﬀ. The number of medical equipment increased by 27.6 %. Due to re-profling in 2020, there was a decrease in the number of hospitalized patients, with an increase in the proportion of patients admitted by emergency care (up to 91 %) and an increase in mortality by 2.7 times. Conclusions. One of the conditions for maintaining high quality of medical care is a balance between the main components of quality: accessibility, timeliness, sufciency, efciency and safety and the speed of its achievement, which in turn depends on the amount of resources and reserves.

Published: April 2023

This research aims to analyze each of the operational and financial factors that can be used as variables influencing decisions and the intensity of hedging. There are two test analysis model used in this study, the first to test the company decision to hedge as a measured by using dummy variables and the second model is used to test the intensity of the company in hedging as measured by the ratio of derivative and natural logarithm of derivative. By using Probit and Tobit regression, the results of the logistic regression test show that financial factors such as financial distress, and leverage, and so operational factors such as foreign sales variables did not influence the firm's decisions and intensity in carrying out hedging activities. Foreign debt variables, profitability, and firm size that include financial factors have a positive influence on company decisions and intensity in carrying out hedging decisions, while the last part of financial factors such as growth opportunity variables only has a positive effect on company decisions in carrying out hedging activities and have no effect on the intensity of firms in hedging activities. The liquidity variable has a negative influence on the decisions and intensity of the company in conducting hedging activities. The originality of this study lies in the intensity factor of the use of hedging on the company's operations and finances in hedging, whereas in previous studies only focused on the influence of factors that can influence hedging decisions.

Exploring Patients’ Needs and Desires for Quality Prenatal Care in Florida, United States
Authors: Fryer Kimberly , Reid Chinyere N. , Cabral Naciely , Marshall Jennifer , Menon Usha 
Published: April 2023

Background and Objective:
High-quality prenatal care promotes adequate care throughout pregnancy by increasing patients’ desires to return for follow-up visits. Almost 15% of women in the United States receive inadequate prenatal care, with 6% receiving late or no prenatal care. Only 63% of pregnant women in Florida receive adequate prenatal care, and little is known about their perceptions of high-quality prenatal care. Therefore, the objective of this study was to assess women’s perceptions of the quality of their prenatal care and to describe their preferences for seeking prenatal care that meets their needs.

Methods:
From April to December 2019, a qualitative study was conducted with postpartum women (n = 55) who received no or late prenatal care and delivered in Tampa, Florida, USA. Eligible women completed an open-ended qualitative survey and a semi-structured in-depth interview. The interview contextualized the factors influencing prenatal care quality perceptions. The qualitative data analysis was based on Donabedian’s quality of care model.

Results:
The qualitative data analysis revealed three key themes about women’s perceptions and preferences for prenatal care that meets their needs. First, clinical care processes included provision of health education and medical assessments. Second, structural conditions included language preferences, clinic availability, and the presence of ancillary staff. Finally, interpersonal communication encompassed interactions with providers and continuity of care. Overall, participants desired patient-centered care and care that was informative, tailored to their needs, and worked within the constraints of their daily lives.

Conclusion and Global Health Implications:
Women seeking and receiving prenatal care prefer a welcoming, patient-centered health care environment. These findings should prompt health care providers and organizations to improve existing prenatal care models and develop new prenatal care models that provide early, accessible, and high-quality prenatal care to a diverse population of maternity patients.
Wireline Logging Operation Uses Water-Based Drilling Fluid in HP/HT Gulf of Mexico Well
Authors: Carpenter Chris 
Published: April 2023

_
This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 210021, “Wireline Logging in High-Overbalance, High-Pressure/High-Temperature Deepwater Gulf of Mexico Well With Water-Based Reservoir Drilling Fluid,” by Martin Tjioe, Jeremy McCaslin, and Jonathan J. Brege, SPE, Shell, et al. The paper has not been peer reviewed.

_
Openhole wireline logging, because of its lower overpull capacity relative to logging while drilling, is subject to increased stuck-tool risk. The risk increases in higher-overbalance environments typical for depleted reservoirs, but other aspects of sticking risk can be managed. The complete paper describes the measures taken in an openhole wireline-logging operation in a deepwater Gulf of Mexico (GOM) well under nearly 7,000-psi overbalance in a high-pressure/high-temperature (HP/HT) slimhole environment using water-based reservoir drilling fluid (RDF) to achieve an efficient logging operation without incurring lost time attributed to conveyance-related issues.

Introduction
The wireline data-acquisition program was planned for an injector well in the deepwater GOM development field. The goal of the well was to maintain reservoir pressure through waterflooding, maximize recovery, and appraise the downdip portion of the fault block. The target was an aeolian sandstone reservoir at a depth of approximately 25,500 ft total vertical depth subsea featuring 19% porosity and permeability in the tens-of-millidarcy range. The reservoir had depletion of 6,850 psi; the well penetrated 174 ft of the reservoir with a hole size of 7 in. and a deviation of 25°.
The injector used an openhole stand-alone-screen completion concept. Water-based RDF was used so that filter-cake material could be removed using a breaker fluid to enable matrix injection. Using a 13.5-lbm/gal mud weight, the wireline operation was performed under a downhole pressure of 17,900 psi (overbalance of 6,950 psi). The maximum temperature recorded during wireline was 320°F.

Wireline Data-Acquisition Program
The wireline program’s objectives were to acquire safely a profile of pressures and mobilities to identify depletion boundaries and to inform completion operations and acquire temperature data to infer the static formation temperature.
During the planning phase, the well was classified as highly challenging, with a high risk of differential sticking based on the analog wireline jobs in the field. The well of interest penetrated the reservoir with the highest depletion encountered in the field at the time; because of its downdip location, it also had one of the higher downhole temperatures in the field.
Several learnings from analog wells that are further detailed in the complete paper included the following:
- Necessity of good hole cleaning
- Reduction of toolstring length
- Necessity of a water-based RDF with good fluid properties
Technology Focus: Formation Damage (March 2023)
Authors: Singh Amit 
Published: April 2023

Identification, prevention, and remediation of formation damage during the life cycle of oil and gas wells are key for our industry to allow wells to perform to their full potential. Increased awareness of potential damage mechanisms along with improvements in laboratory testing equipment and methodologies have proven to be instrumental in efficient prevention and remediation of formation damage in production and injection wells in conventional reservoirs. While the ongoing technical studies and technology developments in the area of formation damage are heavily focused on key damage-mechanism scenarios during drilling and production, such as drilling-fluid-induced damage, scaling, clay swelling, fines migration, and incompatibility of fluid/fluid and fluid/rock in conventional sandstone and carbonate reservoirs, there are new research activities and increased applications of learnings in low-permeability unconventional reservoirs and carbon capture and storage (CCS).
In low-permeability unconventional reservoirs, hydraulic fracturing has proven instrumental for economic and successful development. Injection of a large volume of fracturing fluid water is necessary to place the required quantity of proppant to generate and maintain fracture conductivity, thereby increasing the risk of fracturing-fluid-induced formation damage. New laboratory studies and field trials to select suitable preventive additives in fracturing fluid and optimize flowback processes are being deployed to prevent formation damage not only from gelling materials, friction-reducer chemicals, and water blockage but also from scaling and paraffin during production.
Identification and prevention of formation-damage mechanisms affecting injectivity during CO2 injection in subsurface for CCS and CO2 enhanced oil recovery are critical.
Enjoy the papers chosen this year, some of which highlight my comments and the innovation and successes achieved by our industry in identification, prevention, and remediation of formation damage in conventional reservoirs, which is expected to bring success in area of unconventional-reservoir development and carbon reduction.
