Prediction equations can be used as a useful, inexpensive, and highly accurate tool for estimating Percent Body Fat (PBF) in many countries all over the world. We conducted this study to develop new predictive equations for estimating PBF in children and adolescents aged 6 to 18 years in Ho Chi Minh City (HCMC), Vietnam.

This paper uses the socalled modulated perturbation method by combining the Rayleigh-Schrӧdinger perturbation theory with the Levi-Civita transformation and including a variational parameter. The advantage of the constructed method is demonstrated in calculating the exciton diamagnetic coefficient within the second order of approximation. The results are then compared with recent experimental ones.

This work aims to investigate the mechanism of Pd nucleation and growth onto glassy carbon electrode from ChCl/urea/palladium mixture at room temperature using cyclic voltammetry (CV) and chronoamperometry (CA) techniques. Furthermore, X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy were used to examine the crystalline structure, morphology and compositions of deposited Pd samples.

In this work, we examine cross sections for (α, γ) reactions on p-nuclei, including 90Zr, 121Sb, 151Eu, and 162Er at astrophysically relevant energies. By using our recently developed α optical model potential (α-OMP), the (α, γ) cross sections were calculated within six models of radiative strength functions (RSF) which consisted of the microscopic HFB-QRPA model based on the BSk14 Skyrme force, the HF-BCS theory using Skyrme parameters, the EGLO model, SMLO model, the empirical SMLO (SMLOg) and global semi-microscopic (D1M-QRPAg) models.

This paper examines the role of bank credit to the private sector and private-sector investment in the transition to a low-carbon economy in Vietnam regarding other macroeconomic factors, such as GDP growth rate and electricity consumption from renewable energy. From 1986 to 2021, chronological classification was used. Through the ARDL regression model, the experimental results show that in the short term, credit to the private sector and private-sector investment initially help the economic transition to be effective.

The paper presents the characteristics of the ISO-4037 narrow spectrum X-ray reference fields in 02 different manners: simulation using the SpekPy and measurement using a calibrated ionization chamber. The physical (air Kerma rate) and radiation (X-ray fluence-spectrumaveraged energy, the first and the second half value layers, as well as the beam homogeneity coefficient) quantities were simulated using the SpekPy web-based simulation toolkit.

The parameters of the ISO-4037 wide spectrum (W-series) X-ray reference fields were simulated using the SpekPy web-based simulation software. One of the most important physical quantities (air Kerma rate) and other radiation quantities (X-ray fluence spectrum and its averaged energy, the first and the second half value layers, as well as the beam homogeneity coefficient) were also deduced.

This is a book about general relativity. There is no getting around the fact that general relativity is mathematically challenging, so we cannot hope to learn the theory without mastering the mathematics. Our hope with this book is to “demystify” that mathematics so that relativity is easier to learn and more accessible to a wider audience than ever before. In this book we will not skip any of the math that relativity requires, but we will present it in what we hope to be a clear fashion and illustrate how to use it with many explicitly solved examples.
