Perspective on clinical high-risk for psychosis in Africa [PDF]

Frontiers in Psychiatry, 2023
Clinical High Risk for Psychosis has evolved in recent years as a conceptual and clinical entity, representing a shift in focus from the syndromal psychosis state to a recognition of the pre-psychotic state as a period of potential preventive ...

A study on the countermeasure method for gauge corner cracking by applying the worn profiles of rail

Nihon Kikai Gakkai ronbunshu, 2022
In Japanese railway networks, the gauge corner cracking (GCC) occurs to the head hardened rail of the high rail in curved sections of R600 to R800m. In case of the GCC propagates deeply, it will be a possibility of causes rail broken.

Proposal of the rail profile selection method to reduce gauge corner cracking initiation by mitigating contact conditions of wheel and rail

Nihon Kikai Gakkai ronbunshu, 2022
The gauge corner cracking (GCC) occurs on heat treated rails of the high rail in curved sections with a radius of 600 to 800m. In case of GCC propagates deeply, it may cause rail breakage.

Tribological Study of Chisel Knives in Sandy Soil

Agriculture, 2023
This paper presents the interaction system within the mechanical soil processing process, consisting of two large elements, the metal of the tool and the soil. Due to the two main forces acting on the chisel knives—friction and impact with the sandy soil—

Development of a model for predicting worn profile of rail under the mixed slip conditions

Nihon Kikai Gakkai ronbunshu, 2020
Rail wear does not develop in a short term, but it is closely related to crack initiation. Furthermore, there is a possibility that the worn profile of rail influences the curving performance or the running stability.

Wear Life Prediction on Unfolding Wheel of Steel Ball Detection by Using Numerical Simulation

Journal of Harbin University of Science and Technology, 2020
Wear is the main failure form of unfolding wheel of steel ball, and the unfolding effect on steel ball surface will be failure when the wear of unfolding wheel achieves a certain degree.
