Using direct numerical simulations of rotating Rayleigh-B\'enard convection, we explore the transitions between turbulent states from a 3D flow state towards quasi-2D condensate known as large-scale vortex (LSV). We vary Rayleigh number $Ra$ control parameter and study system response (strength LSV) in terms order parameters assessing energetic content upscale energy flux. By sensitively probin...

PURPOSE The purpose of this study is to compare the refractive error outcomes in the eyes of premature babies with retinopathy of prematurity (ROP) who underwent laser plus lens-sparing vitrectomy (LSV) in one eye and laser alone in the fellow eye. METHODS This is a retrospective study. Fourteen babies with Stage 4A of ROP or worse who underwent laser plus LSV in one eye (Group 1) and laser a...

The aim of this study is to measure the level of both the superoxide dismutase (SOD) enzyme and its substrate, superoxide radicals, in the wall of varicose veins. A total of 44 vein specimens were collected from 24 patients who underwent surgery for varicose veins at Asir Central Hospital (ACH), Abha, Saudi Arabia during the period from October 1999 to November 2000. The patients were 4 males a...

Chronic venous insufficiency (CVI) describes diseases of the lower limb veins in which venous return is impaired and varicose veins and skin ulceration may develop. The roles o f purinergic signalling in regulation of vascular tone in the long saphenous vein (LSV) and in the trophic changes occurring in LSV muscle cells and epidermal keratinocytes in lower leg skin were studied. The purinergic ...

We reported previously that the neuropeptide oxytocin attenuates stress-induced hypothalamo-pituitary-adrenal (HPA) activity and anxiety behavior. This study sought to identify forebrain target sites through which oxytocin may mediate its anti-stress effects. Ovariectomized, estradiol-treated rats received intracerebroventricular infusions of oxytocin (1 or 10 ng/hr) or vasopressin (10 ng/hr), ...

The Laacher See volcano (LSV) is located at the western margin of Neuwied Basin, central part Middle Rhine Basin Germany. Its paroxysmal Plinian eruption c. 13 ka ago (Laacher event; LSE) deposited a complex tephra sequence in whilst distal ashes became one most important chronostratigraphic markers Central Europe. However, some other impacts on landscape formation have thus far been largely ne...
