We show that endothelial cell (EC)– generated vascular guidance tunnels (ie, matrix spaces created during tube formation) serve as conduits for the recruitment and motility of pericytes along EC ablumenal surfaces to facilitate vessel maturation events, including vascular basement membrane matrix assembly and restriction of EC tube diameter. During quail development, pericyte recruitment along ...

The article presents the results of a study performance seed-removing (perforated) tube with diameter 125 mm. To practical mm, 30-saw cotton gin cleaning section was developed. As result study, regression equation derived to determine productivity tube, depending on density raw roller and rotational velocity perforated tube. research, decrease in (from 149.75 54.91 kg/h) established 227 219 kg/...

The effect of tube diameter on two-phase flow patterns was investigated in circular tubes with inner diameters of 0.6, 1.2, 1.7, 2.6, and 3.4mm using air and water. The gas and liquid superficial velocity ranges were 0.01–50 and 0.01–3m/s, respectively. The gas and liquid flow rates were measured and the two-phase flow pattern images were recorded using high-speed CMOS camera. The flow patterns...

The characteristics of particulate matter (PM) emitted from residual fuel oil combustion in two types of combustion equipment were compared. A small commercial 732 kW rated fire-tube boiler yielded a weakly bimodal particulate size distribution (PSD) with over 99% of the mass contained in a broad coarse mode and only a small fraction of the mass in an accumulation mode consistent with ash vapor...

The kidneys of ammocoetes of Petromyzon marinas L . degenerate anteriorly and grow by the proliferation of the posterior nephrogenic tissue (1), which consists of small groups of cells surrounding narrow lumina. The cytoplasm of these cells contains large amounts of glycogen, smooth endoplasmic reticulum, lipid droplets, and mitochondria. This note describes prismatic cristae and granules withi...

This study compared intracuff pressure (ICP) during mechanical ventilation in a variety of currently used endotracheal (ET) and tracheostomy (trach) tube cuffs and related cuff physical characteristics. Tracheostomy tube physical characteristics were also measured. Variation was observed to exist between "just-seal" inspiratory and end-expiratory intracuff pressure during mechanical ventilation...

The hollow inside of single-wall carbon nanotubes (SWCNT) provides a unique degree of freedom to investigate chemical reactions inside this confined environment and to study the tube properties. It is reviewed herein, how encapsulating fullerenes, magnetic fullerenes, C isotope enriched fullerenes and organic solvents inside SWCNTs enables to yield unprecedented insight into their electronic, o...
