To study the influence of the addition of basalt fibers on the mechanical properties, pore structure, and damage evolution characteristics of the cemented tailings backfill (CTB), the uniaxial compression tests, nuclear magnetic resonance tests and scanning electron microscopy analysis were conducted on the CTB with four different content and lengt
Abstract The water-lubricated bearings are usually the state of turbulent cavitating flow under high-speed conditions.And the distribution of cavitation bubbles and the interface effect between the two phases have not been included in previous studies on high-speed deva curl arc angel water-lubricated bearings.In order to study the influence of int
Copper/aluminum alloys are largely utilized in odontological restorations because they are less expensive than gold or platinum.However, tarnishing and important corrosion in intrabuccal prostheses made with copper/aluminum alloys after 28 days of use have been reported.Several kinds of food and beverage may read more attack and corrode these alloy
The paper presents chosen methods for estimating the ROC (Receiver Operating Characteristic) curve, including iphone 13 dallas parametric and nonparametric procedures.Nonparametric approach may involve the use of empirical method or kernel method of the ROC curve estimation.In the analysis, an attempt of comparison of empirical and kernel ROC estim
Agriculture sustainability plays an essential role in country development.This paper aims to examine whether sustainable agriculture is beneficial to economic development in Indonesia.The empirical analysis employs the autoregressive distributed lag model over the data from 1961-2016.The results show that sustainable agriculture significantly contr
