Anesthesia for Robotic Surgeries in Children
Authors: Ahluwalia Pallavi , Ahluwalia Amit 
Published: January 2025

Robot-assisted laparoscopic surgery is increasingly popular in children, including newborns and infants, because it provides a better three-dimensional (3D) view for the surgeon, making the procedure easier. Anesthetists should be aware of the anesthesia-related challenges that a child undergoing robotic surgery may face. Some of these challenges are related to patient positioning, restricted airway and intravenous access, pressure damage to nerves and tissues, and the potential for hypothermia In addition, it is important to understand the physiological changes caused by pneumoperitoneum (PNP) and what effects they have on the different organ systems. Lung ventilatory strategies are needed to maintain oxygenation and prevent hypercarbia and atelectasis, such as limiting peak airway pressure to 25 cm H2O, applying positive end-expiratory pressure (PEEP) of 5 mm Hg, and delivering a tidal volume of 6–7 ml/kg.

Authors: Chergui Yahia 
Published: January 2025

Zinc oxide is a promised component in Technology and Nanotechnology due to its practical properties especially under extended temperature and pressure. In this work parallel and equilibrium molecular dynamics technique (MD) (Raven Supercomputer of Cardiff University, UK) and DL_POLY 4 are used to study the effect of extended pressure and temperature; the system is composed from 2916 atoms of wurtzite type (1458 atoms of Oxygen and 1458 atoms of Zinc) under the range of pressure 0–200 GPa and the range of temperature 300–3000 K; the properties and chemical bonds of ZnO are analysed under isobaric and isothermal ensembles. These results are in the vicinity of available data of theoretical and experimental information. This work is very important in many industrial fields in nanoscale and macroscale fields.
Influence of Working Fluid on the Mean Flow Vortex Structure in Industrial Flow Pipelines of Arbitrary Bend Angle via RANS Simulation
Authors: Church-Forbes Keagan , Zamir A. Koshuriyan Mohammad , A. Abuhatira Ahmed 
Published: January 2025

Numerical simulations of flow through industrial pipelines is important for design purposes in commercial and domestic transport of oil and gas. In this paper we use steady Computational Fluid Dynamics (CFD) to investigate the effect of different working fluids and streamwise bend angle on the spatial distribution, wall shear stress and turbulence kinetic energy of the fully-developed Dean vortex. Using Ansys Fluent, steady Reynolds-Averaged Navier Stokes (RANS) simulations are performed in a parametric study for various gas flows (air, methane and carbon dioxide) and pipe elbow bend angles (90°,60°,45°,30°,0°). Our results show the flow properties (velocity streamlines, turbulence kinetic energy and induced wall shear stress) of the Dean vortex for inflow velocities ranging from 5 to 15 m/s at Dean numbers of O104 corresponding to working fluids having the same inflow mass flux. Reducing the pipe bend angle was found to minimize the wall shear stress and subsequent vortex magnitude for all gas flows types. We discuss these results quantitatively in terms of turbulent kinetic energy/the degree of secondary flow comparing to experimental literature. Reference to pipeline longevity is made.

Published: January 2025

The process of shredding and sorting waste in the Pre Processing method is one of PT Solusi Bangun Indonesia's contributions in overcoming waste and pollution problems. The waste will be shredded into certain sizes and put into the cement kiln. The processing place is called a green zone. In this process, sometimes the material transport contains impurities in the form of metal and the like. This distribution has the potential to cause foreign material to be carried because there is no sorting of waste content. Belt conveyors and dynamic disc screens are often damaged by the metal material. This problem can be overcome with a magnetic separator to separate foreign metals from waste that is channeled using a belt conveyor. The magnetic separator provides protection for the dynamic disc screen and conveyor operating process from foreign material so that the potential for wear on the dynamic disc screen and torn belt conveyor can be avoided. The installation of the magnetic separator position uses a construction based on the optimal position. This study discusses the design and construction of the green zone belt conveyor magnetic separator installation. The construction installation for the magnetic separator aims to facilitate access to maintenance and cleaning, also provide access to dispose of foreign materials and protect the material transport system in the green zone. Before redesign magnetic sparator, the company spent Rp. 389,000,000 maintenance cost from November 2023 to February2024 period. After redesign, it’s can reducing maintenance and repair costs during the period March 2024 to July 2024 with no maintenance related to metal separation.

Factors Influencing the Behavioral Intention to Use Mobile Learning Platform in Higher Education of Changsha, China
Authors: Fan Juan , Li Changhan 
Published: January 2025

Background and Aim: This study explored the factors that influenced student behavioral intention regarding mobile learning platforms. The latent variables investigated in the study include system quality (SQ), service quality (SVQ), information quality (IQ), perceived usefulness (PU), satisfaction (SA), attitude (ATT), and behavioral intention (BI). The objective of the research is to determine the extent to which each variable influences the use of mobile learning platforms.
Materials and Methods: This study surveyed 500 undergraduate students at a public university in Changsha, China, about their views on mobile learning platforms. The data were analyzed using structural equation modeling (SEM) and confirmatory factor analysis (CFA).
Results: The results of the data analysis revealed that each hypothesized path was statistically significant, indicating strong direct relationships between the variables in the model. Notably, information quality exerted the greatest influence on perceived usefulness. The findings underscore the importance of these factors in enhancing the effective use of mobile learning platforms in higher education, boosting student satisfaction and behavioral intentions. This study's strengths include its robust sample size and the use of advanced statistical techniques like SEM and CFA, which provide a rigorous assessment of the model's validity. However, limitations include the study's focus on a single university, which may not fully represent the diverse experiences of students across different institutions. Additionally, while the study highlights critical factors influencing mobile learning, it does not address potential barriers or challenges students might face, such as technological issues or varying levels of digital literacy. Future research could explore these aspects to provide a more comprehensive understanding of mobile learning platforms' effectiveness.

Rauvolfia vomitoria is a browse plant with lactogenic properties and it is available all year round. This research sought to evaluate the proximate, minerals, vitamins composition, fibre fractions and anti-nutritional factors present in the leaves of Rauvolfia vomitoria (RV). Fresh leaves of RV were harvested and taken to the laboratory immediately for chemical analyses following standard procedures. Results obtained showed that RV contained 19.33 % crude protein, 6.64 % crude fibre, 61.69 % nitrogen free extract, 67.60 mg/100g calcium, 180.11 mg/100g magnesium, 68.31 mg/100g phosphorus, 128.16 mg/100g sodium, 47.93 mg/100g potassium, 18.82 mg/100g vitamin A, 64.74 mg/100g vitamin C, 41.62 mg/100g vitamin D, 20.85 mg/100g vitamin E and 13.26 mg/100g vitamin K.

Résumé

cet article a analysé l’impact des dépenses publiques sur la croissance économique en RDC à travers la modélisation VAR. Les résultats des analyses ont démontré que les chocs budgétaires ont un effet positif mais insignifiant sur la production ; la décomposition de la variance de l’erreur de prévision du taux de croissance économique réagit positivement et faiblement aux chocs des dépenses publiques. En moyenne, les dépenses courantes et les dépenses en capital expliquent respectivement 6,10% et 1,71% des variations du taux de croissance du PIB. La politique budgétaire congolaise a donc des effets limités sur l’activité économique réelle.
