downbursts are small-scale, short-lived and energetic events in the atmosphere. they usually occur from the beginning of spring to summer when the weather is more humid and the convective weather conditions are suitable. because of the small-scale property of the downburst, it has sometimes been observed only in a meteorological station and other stations have not observed considerable changes....

The rate of cholesterol deposition during the atherosclerotic process is determined by the balance between the inflow and outflow of plasma lipoproteins in the arterial wall. Whereas the rate of inflow may be measured directly, the rate of outflow has most often been calculated indirectly from lipoprotein uptake by using the 2-compartment model. One objection against such calculations is that l...

Aqueous humor flows out of the eye primarily through the conventional outflow pathway that includes the trabecular meshwork and Schlemm's canal. However, a fraction of aqueous humor passes through an alternative or 'unconventional' route that includes the ciliary muscle, supraciliary and suprachoroidal spaces. From there, unconventional outflow may drain through two pathways: a uveoscleral path...

The renal circulation of the dog was studied by a rheoplethysmographic method capuble of simultaneously recording the time courses of volume, rate, and acceleration of inflow, outflow and difference between inflow and outflow of blood. The studies were done first under control conditions and then under conditions of relatively acute circulatory change induced by intravenous injection of norepin...

conclusions full echocardiographic examination of the right ventricle, including rvot is essential for the diagnosis of this disease. surgical correction appears to be a successful strategy for management of this rare condition in adults. case presentation we report a 40-year-old man who was referred to cardiology clinic for work-up of dyspnea and a heart murmur found on his physical examinatio...

The hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are expressed in pacemaker cells very early during cardiogenesis. This work aimed at determining to what extent these channels are implicated in the electromechanical disturbances induced by a transient oxygen lack which may occur in utero. Spontaneously beating hearts or isolated ventricles and outflow tracts dissected from...

Purpose:​​ ​The​ ​rate​ ​of​ ​conventional​ ​aqueous​ ​humor​ ​outflow​ ​is​ ​the​ ​highest​ ​nasally.​ ​We hypothesized​ ​that​ ​this​ ​is​ ​reflected​ ​in​ ​regionally​ ​different​ ​outflow​ ​structures​ ​and​ ​analyzed​ ​the​ ​entire limbus​ ​by​ ​high-resolution,​ ​full-thickness​ ​ribbon-scanning​ ​confocal​ ​microscopy​ ​(RSCM). Methods:​​ ​We​ ​perfused​ ​pig​ ​eyes​ ​by​ ​anterior​ ​cha...

We study the magnetic reconnection for relativistic plasma in the framework of magnetohydrodynamics and by means of the Particle-In-Cell (PIC) simulation. In the former approach, the magnetic fields are assumed to reconnect steadily inside the diffusion region as assumed in the conventional Sweet-Parker model. The model takes account of the pressure gradient between the diffusion and outflow re...
