For sustainable growth, macro policy makers will need to look at risk management in banking industry and impacts of macro factors on market risk in order to adjust policies and build risk management culture in banking system. What we need to adjust in trade balance, risk free rate and other policies? This is one of reasons for us to conduct this study.This paper measures the Beta CAPM in famous model under impacts of both macro internal and external variables during low inflation time 2015-2020 in the country. The evidence is the fundamental role of risk management in commercial bank has been increasing with new perspectives in management, corporate governance and risk management models. We will estimate effects in risk measurement of one of big listed Vietnam commercial bank, Asia commercial bank (ACB) during the low inflation period 2015-2020 with semiannual data. Through using analysis, synthesis statistics methods, and dialectical materialism method, combined with econometric model with 9 macro variables, we figure out that CPI has a positive correlation with Beta CAPM of ACB, while Risk free rate (Rf) and lending rate have negative correlation with Beta CAPM of the bank. It implies that increase in inflation, together with decrease in Rf and lending rate will increase market risk.Then, one of its major findings is the suggestion of macro and risk management policies for bank and relevant government agencies. Our recommendation can be used for reference and expand researches in many other emerging markets.

This paper employs a range of carefully controlled experiments to develop a detailed understanding of the role of the structure, crystallinity, and chemical composition of polytetrafluoroethylene (PTFE) in driving catalytic reactions during sonication. The new findings demonstrate the significantly enhanced production of hydrogen, hydrogen peroxide, carbon monoxide, and nitrate from water, CO2, and nitrogen in the presence of PTFE during the application of ultrasound. The critical role of PTFE in the degradation of Rhodamine B and para‐nitrophenol, which are important examples of synthetic dyes and nitroaromatic compounds, respectively is demonstrated. By understanding the mechanism and optimization of the catalytic conditions, the system achieves the highest hydrogen production yield reported to date among tribocatalytic, contact‐electrocatalytic, and piezocatalytic systems, where fine‐scale PTFE particles formed during ultrasound contribute to the enhanced activity. Importantly, the impact of PTFE's physical and chemical properties, including hydrophobicity, crystallinity, and atomic composition, on its catalytic performance is investigated. The underlying mechanism of sono‐contact‐electrocatalysis is outlined by examining reactive species generated under various gas environments. These findings provide new insights into the broad applicability of PTFE in redox reactions and highlight key factors influencing its catalytic behavior in aqueous systems for environmental remediation and energy conversion.

This research focuses on the CO2 capture capacity and physical properties of granulated beads using zeolite ANA synthesized from metakaolin as the raw material, which was obtained from using an alkaline solution for hydrothermal treatment at ambient conditions without any additional sources of silica or alumina. The resulting powder was then granulated with bentonite to improve mechanical strength and sodium alginate to perform a cross-linking reaction with barium chloride. The synthesized zeolite powder ANA and the beads were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) with Energy-Dispersive Spectroscopy (EDX). The mechanical strength of the beads was also examined. The CO2 adsorption capacity of the beads was investigated using a CO2/N2 mixed gas stream with activation conditions in vacuum environments at 150 °C, 200 °C, and 300 °C, respectively. It was examined that the mechanical strength of the beads gradually declined with rising activation temperature, as a result of sodium alginate degradation. In addition, the highest CO2 adsorption capacity was recorded about 0.46 mmol/g on the sample which was activated at 200 °C.

This article presents a dynamic model of the TMM-3M heavy mechanized bridge during the frame lifting stage, which is driven by a hydraulic system, constituting the initial phase of the bridge erection process. The model is constructed as a multi-body dynamic system, taking into account the elastic deformation of the rear outriggers, front tires, and front suspension system. The research model integrates a mechanical system controlled by hydraulic cylinders, with pressure being considered as a variable reacting to external loads during the system's operation. Lagrangian equations of the second kind are utilized to establish a system of differential equations describing the oscillations of the system and form the basis for investigating the dynamics of the frame lifting process. The system of differential equations is solved numerically using MATLAB simulation software based on the Runge-Kutta algorithm. The study has revealed laws regarding the displacement and velocity of components within the system, evaluating the stability of the TMM-3M heavy mechanized bridge during operation. This research paves the way for a comprehensive understanding of the working process of the TMM-3M heavy mechanized bridge, aiming for practical improvements to minimize deployment or retrieval time, reduce the number of deployment team members, enhance the automation of the operation process to reduce the workload for operators

Many countries with underdeveloped economies tend to improve military vehicles to enhance their effectiveness by integrating additional equipment into existing vehicles. Armored personnel carriers can be integrated with crane systems and cables to function as cranes for rescue and recovery operations on the battlefield. This paper proposes a dynamic model for a military armored recovery vehicle moving on randomly rough roads in a suspended payload state. The randomly rough roads of classes D, E, and F, as described in the ISO 8068 standard, are considered as factors influencing the vibration of the vehicle during movement. The research model is a 2D multi-body system, considering the elasticity of the tires, suspension system, and cables, while neglecting the elastic slope of the ground. The system's motion differential equations are solved through simulations using Matlab/Simulink software. The results indicate the displacement of the vehicle chassis and the oscillation of the payload corresponding to speeds of 1 m/s, 1.5 m/s, and 2 m/s. The payload's tilt angle can reach nearly 40° when the vehicle moves at a speed of 2 m/s on a type F road, corresponding to a travel distance of about 30 meters. Meanwhile, the maximum tilt angle is about 19° when the vehicle moves at the same speed on a type D road. The chassis, boom, and payload experience stronger oscillations when the vehicle moves faster and on rougher terrain. The paper recommends practical engineering solutions to minimize load oscillations during vehicle movement. The findings of this paper provide a basis for evaluating the operational capability of an armored personnel carrier integrated with a crane, contributing additional theoretical insights into machine dynamics and holding significant importance in the military field

Mobile repair vehicles play an indispensable role on the battlefield and are increasingly being improved to enhance their effectiveness. When moving to repair locations on the battlefield, they often tow trailers, which include power generator sets. In some cases, these generator sets are replaced by trailers to transport ammunition or carry wounded soldiers. The article proposes improvements to the suspension system on the generator trailers and discusses the impact of vehicle speed and random road roughness on the movement of the mobile repair vehicle-trailer combination before and after the improvements. A dynamic model of the multi-body system is constructed, with the towing vehicle being a three-axle truck. The random roughness profile of the road surface is determined from simulation results based on ISO 8068 standards. The equations of motion are established using Lagrange's method and solved through simulation using Matlab software. The results of the article indicate the oscillation of the mobile repair vehicle-trailer combination when traveling at speeds of 36 km/h and 54 km/h on road surfaces with random roughness levels of class D and class E. After the improvement of the suspension system on the generator trailers, smoother trailer motion is observed. The study has shown that the vertical oscillation amplitude of the trailer decreased by up to 18 %, while the oscillation speed decreased by as much as 40 %. The findings provide a basis for further improving the suspension system on generator trailers to minimize oscillations, which is crucial for replacing generator trailers with specialized trailers for transporting ammunition or wounded soldiers on the battlefield. This is a significant issue in the field of national security and defense

The paper presents a dynamic model of the TMM-3M heavy mechanized bridge during the span lowering stage. The model is constructed as a multi-body mechanical system, taking into account the elastic deformation of the cable, rear outriggers, front tires, and front suspension system. It is a mechanical model driven by a cable mechanism. Lagrangian equations of the second kind have been applied to establish a system of differential equations describing the oscillations of the mechanical system and serve as the basis for investigating the dynamics of the span-lowering process. The system of differential equations is solved using numerical methods based on MATLAB simulation software. The study has revealed laws of the displacement, velocity, and acceleration of components within the mechanical system, especially those related to the bridge span depending on the choice of the drive speed of the engine during lowering by operator. The research results show that the lowering time increases from 52 seconds to 104 seconds when the engine speed decreases from 1800 rpm to 900 rpm. The tension force on the cable is surveyed to confirm the safety conditions during the span-lowering process. The study also provides recommendations for selecting appropriate engine speeds to minimize span-lowering time while ensuring the safety conditions of the TMM-3M bridge during the span-lowering process. This research is an important part of a comprehensive study on the working process of the heavy mechanized bridge TMM-3M to make practical improvements, aiming to reduce deployment time, decrease the number of deployment crew members, and increase the automation capability of the equipment

This study investigated the association between serum uric acid (SUA) levels with rapid decline of the estimated glomerular filtration rate (eGFR) in type 2 diabetes (T2 DM) patients. A prospective cohort study was conducted in a community-based hospital in Vietnam. We followed 405 T2DM patients with normal kidney function for five years. Rapid progression of kidney function was defined as an average annual decrease of eGFR of at least 4 mL/min/1.73 m2 and was found in 16.0% of patients. Patients in the SUA high tertile ( ≥6 mg/dL) had higher BMI (p = 0.004), lower HbA1c (p = 0.001), lower eGFR (p < 0.001) and higher rate of hypertension than low and middle tertile. After adjusting for age and sex, rapid progression of renal function was significantly associated with SUA level (OR = 1.22, 95% CI 1.02–1.45, p = 0.026). This association was marginally significant when more covariates were included in the model (OR = 1.20, 95% CI 0.99–1.46, p = 0.065). However, the association between tertiles of SUA and rapid decline of eGFR was not statistically significant. This study demonstrates neither a strong significant association between SUA and rapid decline of eGFR nor evidence to refuse the role of SUA levels in the increased risk of renal function decline in in T2DM patients.

The push of levers of digital boom technology in the era of industrial revolution 4.0 has created great impetus for economic development, especially in maintaining and revitalizing the smokeless tourism industry. That makes even more sense in the context of the current covid 19 pandemic and increasing social distancing. It can be said that the appearance of the COVID-19 epidemic has adversely affected the economy, fundamentally changing people's living and consumption behavior. Meanwhile, business sectors are facing the risk of production shutdown because of capital flow downturn, idle operation or bankruptcy because of covid19. The reason for social distancing forces people to not be able to travel freely to carry out travel and shopping behaviors like before. Previously normal activities were restricted from being concentrated in large places, leading to a business industry that was supposed to be super-profitable and a major contributor to a high GDP structure such as tourism, which is facing a dilemma. The tourist season is coming, but the number of tourists suddenly drops because of social distancing. That risk poses a big obstacle to the tourism industry, but it will be an opportunity if we know how to take advantage of the 4.0 technology revolution. That will help make use of smart digital technology applications to exploit and develop different types of tourism. Research and propose ideas to apply VR technology to develop smart tourism industry, helping tourists from all over the world can use and experience famous tourist attractions of Vietnam. VR virtual reality technology allows to maintain and develop tourism activities in the context of the current pandemic.
