ABSTRACT The methods developed for determination of lime requirements (LR) are based on widely accepted principles.However, the formulas used for calculation have evolved little over recent decades, and in some cases there Wooden Keychain are indications of their inadequacy.The aim of this study was to compare the lime requirements calculated by th
Accurate measurement of coal gas permeability helps prevent coal gas safety accidents effectively.To predict permeability more accurately, we propose the IDBO-BPNN coal body gas permeability prediction model.This model combines the Improved Dung Beetle algorithm (IDBO) with the BP neural network (BPNN).First, the Sine chaotic mapping, Osprey optimi
We posit that curiosity, an epistemic emotion, is an integral part of entrepreneurial education, entrepreneurial activities, and learning, which seek to develop an entrepreneurial mindset, a form of cognitive ability.The purpose of the present investigation was to examine the influence of autonomy and competence satisfaction on epistemic curiosity
This paper investigates the impact of jumps in forecasting co-volatility in the presence of leverage effects for daily crude oil and gold futures.We use a modified version of the jump-robust covariance estimator of Koike (2016), such that the Indole 3 Carbinol estimated matrix is positive definite.Using this approach, we can disentangle the estimat
