COPD = chronic obstructive pulmonary disease; PEEP = positive end-expiratory pressure. The most frequent reason for admission to an intensive care unit is need for ventilatory assistance. At least, this is my experience over the past 20 years from working in university and county hospitals. Regardless of the illness that provokes respiratory insufficiency, the majority of patients with respirat...

Introduction: In laser surgery, the laser beam can evaporate and cut the tissue like a small surgical knife when the tissue temperature is heated to 100 degrees Celsius. a complete understanding of the distribution of damage in both pathologic tissue and surrounding tissue is necessary. Although the test is the most realistic solution for treating medical problems, for this rea...

Laser irradiation parameters, especially the laser fluence and the number of pulses are very important factors affecting microstructures formation and improvement of the surface characteristics in different medical, electronic and the other industrial applications. Information about the fluence domain and the number of pulses for the formation of the structures is very important and determines ...

A few of the presented soil behavior models are capable of predicting the triggering and post liquefaction and also shear band mechanism through the soil media. The assessment of earth-dam body behavior as a soil structure made of cohesive soil in core and non-cohesive soil as the core supports, including water interaction at upstream through earthquake upon a multi-line constitutive equations ...

This article studies the particle temperature distribution depending on the laser radiation power and the particle’s trajectory and velocity. The uneven heating of particles moving in the laser radiation field is identified. The regimes of laser heating without melting, with partial melting, and with complete particle melting are considered.

Abstract Memory effects in seismology—such as the occurrence of aftershock sequences—are implicitly assumed to be governed by time since main event. However, experiments are yet identify if memory structural or time-dependent mechanisms. Here, we use laser interferometry examine fluctuations deformation which naturally emerge along an experimental shear fault within a compressed frictional gran...

AIMS Studies in guinea-pig cardiomyocytes show that reactive oxygen species (ROS) produced by a few mitochondria can propagate to their neighbours, triggering synchronized, cell-wide network oscillations via an ROS-induced ROS release (RIRR) mechanism. How mitochondria in cardiomyocytes from failing hearts (HF) respond to local oxidative stress perturbations has not been investigated. Since mit...

Galaxy interactions/mergers, gravitational instabilities and density waves, such as bars, are frequently invoked to trigger starbursts. These mechanisms have been explored through numerical simulations, with the help of various star formation recipes. Gravitational instabilities are necessary to initiate star formation, but the main trigger might be the gas flows, to provide sufficient fuel in ...

In networked control systems, the advent of eventtriggering strategies in the sampling process has resulted in the usage reduction of network capacities, such as communication bandwidth. However, the aperiodic nature of sampling periods generated by event-triggering strategies has hindered the schedulability of such networks. In this study, we propose a framework to construct a timed safety aut...
