Introduction: Precisely determining the characteristic stress value of a rock progressive failure process has important theoretical Oven Control PCB and practical significance for reasonably defining the rock deformation and failure stage, mechanical mechanism, and design parameters.Methods: Based on the energy characteristics in the process of roc
Background: Preventing COVID-19 in Gaza is crucial due to the devastation of advanced health services infrastructure by war.Despite the high protection offered by COVID-19 vaccines against severe disease, a 2021 survey in Gaza found only half of the population was vaccinated, and one-third was vaccine-hesitant.This follow-up study conducted in Marc
A model of system maintenance which ensures secure operation of the system is investigated.To this end, mathematical model of a controlled semi-Markov process with catastrophes is used.The model allows to take into account Sauces the features of self-manifestation of failure (the time has an arbitrary distribution) and features of disaster occurren
A thrombus is a blood clot that forms on a surface, and can grow and detach, presenting a high risk for stroke and pulmonary embolism.This risk increases with blood-contacting medical devices, due to the immunological response to foreign surfaces and altered flow patterns that activate the blood and promote thromboembolism (TE).Abnormal blood trans
