Background: Dental needle aspiration is a rare complication of oral procedures given the advances in medical technology.Aspirations in general may also be asymptomatic, apart from the possible remote history of upper airway irritation at the time of induction.Clinicians should take a detailed history and examination, along with appropriate diagnost
To converge the conditions of organic water-coal fuel composition combustion in the typical power equipment we developed a new approach and installed an experimental setup, eliminating the traditional fixing the fuel droplets on the thermocouples or rods.Specialized cone-shaped chamber was used to implement the process of lingering of organic 730 s
Meta-heuristic algorithms have become an arising field of research in recent years.Some of these algorithms have proved to be efficient in solving combinatorial optimization problems, particularly knapsack problem.In this paper, four meta-heuristic algorithms are presented particle swarm optimization, firefly algorithm, flower hlpro4sw pollination
Across the Gobi Desert in China and Mongolia, millions of newly planted trees struggle to survive amid adverse ecological conditions.They were planted by a wide variety of actors in an attempt to protect, restore, or modify the local environment, despite evidence of their negative consequences upon local ecosystems.This paper investigates how these
