Authors: Putri Anggi Resina , Susanti Nadya 
Published: May 2024

<p><strong>Background</strong><strong>: </strong>Factors that can influence the success of the educational process are family environmental factors, school environment, and community environment. The role of parents is to provide materials and help their children when they experience difficulties in the learning process. Language skills emerge in early childhood and are critical in promoting later literacy competencies, such as reading and writing. The period from birth to age 3 is critical for language development, as nearly all typically developing children acquire important language skills by age 3. During this period, children's home environment is especially important, as parents are the main providers of language input and support, allowing most children to acquire a basic foundation of language.</p><p><strong>Methods: </strong>This study used a cross sectional study design, which was conducted in Surakarta City. A sample of 100 people was selected using a random sampling technique. Data collection was performed using a questionnaire and analyzed by path analysis.</p><p><strong>Results:</strong> The direct relationship between expressive language abilities of children who have mothers with higher education is 2.2 units higher than children with mothers with low education (b=2.2; 95% CI= 0.9 to 3.5; p= 0.001). A high home literacy environment had a log odd of experiencing good expressive language skills of 2.04 units higher than children with a low home literacy environment (b=2.04; 95% CI= 0.7 to 3.3; p= 0.002). The indirect relationship between maternal higher education and expressive language abilities through the child's home literacy environment is statistically significant. Children who have mothers with higher education have log odd for high language expressive abilities of 2.8 units higher than children with mothers with low education (b=2.8; 95% CI= 1.7 to 3.9; p= &lt;;0.001). </p><p><strong>Conclusion:</strong> A child's good expressive language abilities are influenced indirectly by the mother's high education through a high home literacy environment.</p>

A Regional Shallow Décollement at the Front of the Mexican Fold and Thrust Belt: Microstructure of the Santiago Shale
Authors: Valdez-Barrera Lenin Ivan , Cerca Mariano , Jimenez-Camargo Jubier Alonso , Cortés-Prado César A. 
Published: May 2024

Abstract
This contribution analyses the role played by the mechanical properties of a decollément shale layer in the evolution of the Mexican Fold and Thrust Belt (MFTB). The mobility of overpressured shales can accommodate large strains by grain-scale plastic mechanisms, and affect the folding and thrusting styles of the overburden. Research on shale deformation mechanisms is necessary to improve the knowledge of these processes and their influence on the structural style of fold and thrust belts. The ductile behavior of rocks involving grain-scale plasticity was documented in the Jurassic Santiago shale sequence using geological mapping, microstructural observations on thin-oriented sections, and scanning electron microscopy (SEM) imaging. Structural styles such as detachment folding, fault-bend folding, and shale-cored fold-thrusts were observed at the regional scale. At the outcrop scale, the shale developed strong foliation and pencil cleavage, with immersed packstone boudins. Observed structures include thrusting, soft and open folds, and buckle folding. In thin section, the ductile textures include a strong penetrative foliation with lenticular and wavy-parallel laminae composed of carbonates, ribbons of reoriented clays and organic matter (clay+OM), s-c structures, porphyroblasts microtextures, development of oblique cleavage concerning folded foliation (crenulation cleavage), and carbonates dissolution. The Santiago shale shows also evidence of brittle deformation including calcite-filled fractures and cataclastic gouges. X-ray diffraction (XRD) analysis of the clay size fraction suggests that the authigenic calcareous shale was deformed in conditions of the deep diagenetic zone (between 100 and 200°C) and fluid overpressure (&gt;70 MPa). The results help to improve the understanding of ductile microstructure and its role in shale deformation cretaceous cover, promoting the formation of localized fault propagation folds in the overburden. This study aims to open new perspectives in the kinematics and rheology interpretations for this sector of the MFTB, highlighting the role of the décollement layers during the progression of the orogen.

Abstract
Carbon capture and storage (CCS) is one of the primary mechanisms being studied and implemented globally toward the push for a healthier planet. Dynamic modeling of carbon dioxide (CO2) storage in depleted gas reservoirs requires a great amount of integration between various domains, including reservoir engineering, production engineering, geomechanics, well integrity, and geology. In this paper we will highlight various important areas of integration that are necessary to consider while conducting a dynamic modeling study for CO2 storage.
Multidomain integration is required at various stages of the dynamic modeling of CO2 storage in depleted gas reservoirs. To decide the suitable boundary conditions, it is important that geological aspects of the structure are fully integrated. Thorough cyclic integration between the reservoir, production engineering, and well integrity is needed to ensure that realistic operational conditions for the injection well are computed and considered during dynamic modeling.
In this paper we will show, with the help of a recent case study, the methodology and importance of multidomain integration for accurately modeling the CO2 storage in a depleted gas reservoir. Integration between geology and reservoir engineering is crucial while selecting the CO2 storage sites as well as while deciding the applicable boundary conditions. Geomechanics plays a vital role in defining the fracture gradient for each well for different formations. This fracture gradient is an important value to consider while selecting the bottomhole injection pressure limits for the dynamic simulation. Similarly, a close integration between reservoir engineering, production engineering, and well integrity is crucial to establish valid operational conditions, pressure, and temperature, which will enable the required injection rates to be injected without encroaching toward freezing conditions and hydrate formation, among others.
Several innovative integration workflows were created during this study. These include integration of geology and reservoir engineering for boundary conditions selection, integration of geomechanics and dynamic modeling, and integration of production, reservoir engineering and well integrity for selection of valid operational conditions.

Abstract
Mature oil fields tend to face drastic changes at both levels of production and operational efficiency leading to increasing demand of manpower & logistics as well as decreasing trend of equipment uptime that results in associated production deferrals.
A key to sustainability of mature oil fields is to ensure high levels of utilization of existing resources and defy the progressive logistical demand to maintain profitability margins at maximum levels. such objectives can be approached by transformation to digital oil field.
Digital oilfield incorporates data acquisition through installation of necessary sensors & meters, data management & analytics, remote monitoring, remote control & automated workflow.
Gulf of Suez Is one of the mature oil basins that started oil production in mid-1960s and suffers from the same challenges facing mature oil fields. A vision of going digital was adopted and various digitalization projects are being deployed to allow remote monitoring & Control of gas lifted wells. which suggest several values ;
Productivity: Digital oil field supported production optimization by optimum lift gas utilization giving more room for reactivation of shut in wells. Accessibility to all wells allows proper production deferral management during any production upset. Innovative data driven diagnostic tools supports troubleshooting and setting priorities of interventions.
Operational Efficiency: harmony of production system can be improved dramatically with remote monitoring and control resulting in higher uptime of key equipment such as gas lift modules. logistics and manpower is a major part of operating cost of any mature field, incorporating remote monitoring and control will decrease the need of helicopter & boats trips to manual investigate production drops, efficient distribution of lift gas resulted in less gas lift demand & lower load on compression facilities.
Profitability: Imperative impact of digital oil field hitting two birds with one stone; production & cost optimization will boost the profitability margin.
the progressive implementation of digital oilfield in the subject asset succeeded to achieve 3% production increase, alleviate the demand of logistics and manpower, decrease the gas lift demand and managed to stop one gas lift module which had positive impact on asset profitability.
Digital oil field is a good investment for green fields but it is a vital investment for mature field and a key enabler for business sustainability.

Authors: Fathey Islam T. , Azer Amir S. , Raheem Islam M. Abdel 
Published: May 2024

Abstract

Background: The rising demand for improved aesthetics has driven the utilization of recently introduced aesthetic materials for creating custom post and core restorations. However, information regarding the fracture resistance of these materials remains unclear, which limits their practical use as custom post and core restorations in clinical applications.
Aim of the study: This study aimed to evaluate the fracture resistance of three non-metallic esthetic post and core restorations and their modes of failure.
Materials and Methods: Thirty-nine single-rooted human maxillary central incisors were endodontically treated. A standardized post space preparation of 9mm length was performed to all teeth to receive custom-made post and core restorations. The prepared teeth were randomly allocated to receive a post and core restoration made of one of the following materials (n=13): glass fiber-reinforced composite (FRC), polyetheretherketone (PEEK) and polymer-infiltrated ceramic-network (PICN). An intraoral scanner was used to scan all teeth including the post spaces. Computer-aided design and computer-aided manufacturing (CAD-CAM) was used to fabricate post and core restorations. Post and core restorations were cemented using self-adhesive resin cement. All specimens were subjected to fracture resistance testing using a universal testing machine. Failure mode analysis was assessed using a stereomicroscope and SEM. The data was statistically analyzed using One-Way ANOVA test followed by multiple pairwise comparisons using Bonferroni adjusted significance level.
Results: Custom PEEK post and core restorations displayed the least fracture load values at 286.16 ± 67.09 N. In contrast, FRC exhibited the highest average fracture load at 452.60 ± 105.90 N, closely followed by PICN at 426.76 ± 77.99 N. In terms of failure modes, 46.2% of specimens with PICN were deemed non-restorable, while for PEEK and FRC, these percentages were 58.8% and 61.5%, respectively.
Conclusions: Within the limitation of this study, both FRC and PICN demonstrated good performance regarding fracture resistance, surpassing that of PEEK.
Analysis of Transient Turbulent Flow in the Pilot Stage of a Deflector Jet Servo Valve
Authors: Wu Lin , Zou Xian 
Published: May 2024

Abstract

The performance of a deflector jet servo valve is highly affected by the characteristics of the pilot stage flow field. In this paper, the transient results of the large eddy simulation (LES)-based numerical simulation of the pilot stage flow field are presented. The LES results are validated against particle image velocimetry, showing that the LES method can predict the transient turbulent flow. The length of the potential core of the jet assuming from the nozzle and the position of the jet impinging on the V-groove have great relations with the inlet pressure. Traveling cavitation in the deflector begins to appear when the inlet pressure reaches 6 MPa. The increment in inlet pressure enhances cavitation and cavitation shedding. Snapshot proper orthogonal decomposition(snapshot POD) analysis, based on LES, is applied to decompose the instantaneous velocity fluctuation into coherent structures and turbulent velocity components. The relationships between each coherent structure and wall attachment flow, cavitation phenomena, and vortex pairs are discussed. The vortex in Mode 2 contributes to deflecting the jet from the nozzle and causing part of the fluid to flow along the side wall in the V-groove. Through the fast Fourier transform (FFT) result of the POD coefficient, it is known that the traveling cavitation near the side wall of the V-groove is related to Mode 4. This research contributes to the mathematical modeling and improving the stability of the flow field.

Acoustic Insights into Facies-Dependent Pattern and Characterization for Aiding Exploration and Sequestrations Efforts in Bassein Carbonate Formations
Authors: Kalita Hirakjyoti , Sharma Ravi , Dhiman Ashish , Pandey Prabhat , Panwar Neha 
Published: May 2024

Abstract

Most carbonate formations offer challenges for comprehensive characterization and, therefore, optimized exploration and recovery of hydrocarbon resources and for the sequestration of greenhouse gases (GHGs) to meet sustainable climate goals. The Bassein Formation in India's Western Offshore has been a prolific oil and gas producer for the last three decades. However, due to the lack of understanding about the distribution of heterogeneous facies, the recovery of hydrocarbon often proves discouraging. An insight into the patterns of seismic rock properties of such heterogenous reservoirs has promise not only for the recovery of the resources but also for the use of the formations for geological sequestration of GHG. This study investigates laboratory-measured ultrasonic velocity and attenuation behaviors in these formations and identifies a pattern between estimated elastic properties to linked facie heterogeneity and associated saturation. The interplay between rock composition, pore structure, and fluid saturation provides crucial insights for the optimized recovery of hydrocarbon from this formation. Dry ultrasonic measurements established the baseline velocity data for the samples grouped under homogeneous, intermediate, and heterogeneous categories. Upon brine saturation, while the homogeneous samples show a modest increase in velocity, the intermediate and the heterogeneous samples exhibit more pronounced velocity alterations. Also, the compressive (Vp) to shear (Vs) velocity ratio registers notable changes post-saturation, particularly in intermediate and heterogeneous samples. Amplitude attenuation analysis highlights intensified post-saturation attenuation in heterogeneous samples, with marginal changes in homogeneous samples. Additionally, this study introduces a novel approach by integrating amplitude attenuation analysis alongside velocity measurements, providing a comprehensive understanding of the seismic rock properties in carbonate formations. These findings are instrumental in quickly detecting heterogeneity and helped develop input parameters for the rock physics models to forecast elastic properties and fluid behavior in complex formations such as carbonates. This enhanced understanding of seismic rock property behavior (attenuation) will contribute to optimizing reservoir property prediction for time-lapse scenarios and identify favorable zones for hydrocarbon recovery and storage of GHGs and hydrogen in the Bassein formation.

Abstract

Rapid urbanization cupped with climate-induced migration making the cities more exposed to recurrent climate extremes. Most rural to urban migrants move towards mega/primary cities for better livelihood opportunities creating an overburden on the existing dense population. This study developed a framework for building climate-resilient secondary cities to divert the displaced people rather than overcrowded megacities. To develop a town/city-wide climate adaptation plan by the citizens, the study has used a Locally-Led Adaptation (LLA) approach. This paper proposes a comprehensive seven-step approach for the implementation of a climate-resilient migrant-friendly town model. The steps outlined include city selection, establishment of a local adaptation center, identification of climate-vulnerable migrant hotspots, formulation of Local Climate Action Plans (LCAP), Ward-level Climate Action Plans (WCAP), and Town-level Climate Action Plans (TCAP), and scaling up. This structured approach will help to address the multifaceted challenges posed by climate change-induced migration and foster sustainable development in vulnerable communities. Acknowledging the diverse geographical and economic contexts of different locations, the model emphasizes the need for tailor-made strategies.
