The ability to resolve closely spaced frequencies of two high-resolution AR spectral methods, the Burg's and Marple's approaches, is examined by using time series of coastal currents measured in waters of Canary Islands. We emphasise their usefulness to resolve tidal harmonic components with close frequencies and low frequency components.
results sixty patients were involved in this study. in asv mode, values including peak airway pressure (p-peak), end-tidal carbon dioxide (etco2), tidal volume and respiratory dead space were significantly lower than simv mode. although the mean value for dynamic compliance had no significant difference in the two types of ventilation, it was better in asv mode. methods in a crossover study, pa...
Tidal energy is the most foreseeable form of renewable energy. Tidal energy can be harnessed by tidal barrage, tidal fence and tidal current technologies. Present efforts are focused on diffuser augmented tidal turbines that exploit the kinetic energy of the tidal currents. The power output by a tidal turbine is directly proportional to the cube of velocity of incoming fluid flow. Thus, even a ...
In the southern Weddell Sea, several water masses with the capability to form Antarctic Bottom Water (AABW) meet near the continental shelf break. The internal tidal field over the continental shelf break here is of interest due to its potential to mix these waters and form AABW. A modified version of the Princeton Ocean Model (POM) was utilized to investigate the internal tidal fields generate...
[1] Ship and mooring data collected off the coast of New Jersey are used to describe the nonlinear internal wave (NLIW) field and the background oceanographic conditions that formed the waveguide on the shelf. The subinertial, inertial, and tidal circulation are described in detail, and the background fluid state is characterized using the coefficients of the extendedKorteweg–deVries equation. ...
Tidal wetland restoration efforts can be challenging to monitor in the field due to unstable local conditions and poor site access. However, understanding how restored systems evolve over time is essential for future management of their ecological benefits, many of which are related to vegetation dynamics. Physical attributes, such as elevation and distance to channel play important roles in go...
Influenza virions bud preferentially from the apical plasma membrane of infected epithelial cells, by enveloping viral nucleocapsids located in the cytosol with its viral integral membrane proteins, i.e., hemagglutinin (HA), neuraminidase (NA), and M2 proteins, located at the plasma membrane. Because individually expressed HA, NA, and M2 proteins are targeted to the apical surface of the cell, ...
Background : Chronic Obstructive Pulmonary Disease (COPD) represents a major public health problem. The course of COPD is characterized by episodic periods of worsening symptoms, termed exacerbations. Supplemental oxygen should be given to patients with COPD exacerbation without causing CO2 retention. Arterial blood gas sampling is the gold standard for monitoring adequate oxygenation and for...
using tidal potential, the effect of tide on the gravity field, crustal deformation due to tidal force, and gravity variations resulted from the crustal deformation are presented. tidal potential is divided into constant and periodic (diurnal and semi-diurnal) constituents, and for each constituents crustal displacements in radial, south-north, and east-west directions are computed. the aforeme...
BACKGROUND A prospective sequential study on continuous ambulatory peritoneal dialysis (CAPD) and three techniques of automated peritoneal dialysis (APD) was conducted to assess peritoneal clearances, the influence of peritoneal permeability on nocturnal APD clearances and the suitability of the peritoneal equilibration test (PET) for predicting clearances on APD. METHODS After performing a P...
