Introduction: Intranodal pathways of atrioventricular (AV) node play a vital role in the delay of conduction time in response to various atrial inputs. The present study was aimed to determine the frequency-dependent electrophysiological properties of concealed slow pathway according to a functional model of isolated rabbit atrioventricular node preparation after fast pathway ablation. Meth...
Biochar is a solid material of biological origin obtained from the biomass carbonization, designed as a mean to reduce greenhouse gases emission and carbon sequestration in soils for a long time. Biochar has a wide spectrum of practical utilization and is applied as a promising soil improver or fertilizer in agriculture, or as a medium for soil or water remediation. Preparations of biochar incr...
Charred biomass generated by wildland fire has attracted increased interest as a functional component of terrestrial ecosystems. Black carbon (C) in the form of char is a widespread but unique material contributing to biogeochemical processes including long-term carbon storage and soil productivity. These functions have long been recognized by the biogeochemical and soil sciences, but have so f...
Hybrid laser processing for precision microfabrication of hard materials, in which the interaction of a conventional pulsed laser beam and another medium on the material surface leads to effective ablation, is reviewed. The main role of the medium is to produce strong absorption of the nanosecond laser beam by the materials. Simultaneous irradiation with the ultraviolet (UV) laser beam and the ...
Silicon carbide mirrors are sought for a variety of aerospace applications. While optical polishing techniques are straight forward for flat and spherical surfaces, material removal rates for this hard, brittle material are too low for affordable processing of conventionally machined, ground, or as-produced surfaces. The problem is more severe for aspheres. This paper reports on the use of pico...
Background and Purpose: Cancer is a major public health problem worldwide and is one of the most leading causes of death in the world. The number of cancer survivors is increasing because of early detection, new treatment methods and growth of the population. Also, the extensive researches continue to achieve the best practical treatment. Hyperthermia by High-Intensity Focused Ultrasound (HI...
