A tidal bore is a natural and fragile phenomenon, which is of great importance for the ecology of an estuary. The bore development is closely linked with the tidal range and the river mouth shape, and its existence is sensitive to any small change in boundary conditions. Despite their ecological and cultural value, little is known on the flow field, turbulent mixing and sediment motion beneath ...

Understanding temporal patterns in distribution, occurrence and behaviour is vital for the effective conservation of cetaceans. This study used cetacean click detectors (C-PODs) to investigate spatial and temporal variation in occurrence and foraging activity of the Indo-Pacific bottlenose (Tursiops aduncus) and Indian Ocean humpback (Sousa plumbea) dolphins resident in the Menai Bay Conservati...

OBJECTIVE To determine whether tidal volume is associated with mortality in critically ill, mechanically ventilated children. DATA SOURCES MEDLINE, EMBASE, and CINAHL databases from inception until July 2013 and bibliographies of included studies without language restrictions. STUDY SELECTION Randomized clinical trials and observational studies reporting mortality in mechanically ventilated...

Introduction: Specific ventilation (SV) is defined as a dimensionless quantity of inhaled gas ventilation that occurs during tidal breathing and is calculated as tidal volume divided by functional residual capacity [1]. 1H MRI was previously proposed to regionally quantify SV, using inhaled O2 as a contrast agent [2]. Our objective was to develop a novel and rapid way to measure whole lung and ...

RATIONALE Mechanical ventilation of severe acute asthma is still considered a challenging issue, mainly because of the gas trapping phenomenon with the potential for life-threatening barotraumatic pulmonary complications. PATIENT CONCERNS Herein, we describe 2 consecutive cases of near-fatal asthma for whom the recommended protective mechanical ventilation approach using low tidal volume of 6...

[1] Surface tidal circulation over the continental shelf of Duck, North Carolina, was explored using surface current observations measured by a high-frequency (HF) radar. The Ocean Surface Current Radar (OSCR) was deployed at the U.S. Army Corps of Engineers (USACE) Field Research Facility (FRF) in Duck, North Carolina, during 1–30 October 1994 and measured surface current at 20-min intervals a...

Tidal streams are complex watercourses that represent a transitional zone between riverine and marine systems; they occur where fresh and marine waters converge. Because tidal circulation processes cause substantial turbulence in these highly dynamic zones, tidal streams are the most productive of water bodies. Their rich biological diversity, combined with the convenience of land and water tra...

We study the tidal effects of a Kerr black hole on a neutron star in black hole-neutron star binary systems using a semi-analytical approach which describes the neutron star as a deformable ellipsoid. Relativistic effects on the neutron star selfgravity are taken into account by employing a scalar potential resulting from relativistic stellar structure equations. We calculate quasi-equilibrium ...
