Secular trends and evaluation of complex interventions: the rising tide phenomenon

BMJ Quality & Safety, 2015
Evaluations of service delivery interventions with contemporaneous controls often yield null results, even when the intervention appeared promising in advance. There can be many reasons for null results.

The influence of tidal dynamics on exchange of meroplankton (Bivalvia, Gastropoda) between the Busse Lagoon and adjacent marine area of the Aniva Bay

Известия ТИНРО, 2018
Exchange of Bivalvia and Gastropoda larvae between the Aniva Bay and Busse Lagoon is described on results of the plankton survey conducted in the connecting Suslov Channel in 2014. Taxonomic composition of meroplankton is described.

Seasonal Temperature Distributions and Variations in Salt Marshes: Field Investigation and Numerical Simulation

Water Resources Research
Soil temperature regulates biogeochemical processes and is a key environmental factor affecting salt marsh ecosystems. Previous studies on soil temperature and heat transport in intertidal marshes predominantly focused on short‐term changes, leaving ...

The Potential of Tidal Energy Production in a Narrow Channel: The Gulf of Morbihan

Journal of Marine Science and Engineering
The tidal currents of the Gulf of Morbihan reach up to 3.5 m/s within a narrow (200 m large) channel connecting the sea to the inner part of the gulf. In this study, a Telemac2D model validated with a large dataset of field measurements is used to assess

Global Earth Response to Loading by Ocean Tide Models [PDF]

Mathematical and programming techniques to numerically calculate Earth response to global semidiurnal and diurnal ocean tide models were developed. Global vertical crustal deformations were evaluated for M sub 2, S sub 2, N sub 2, K sub 2, K sub 1, O sub

Analyses of the solid earth and ocean tidal perturbations on the orbits of the GEOS-1 and GEOS-2 satellites [PDF]

The luni-solar tidal perturbations in the inclination of the GEOS-I and GEOS-II satellite orbits were analyzed for the solid Earth and ocean tide conditions.

Tidal Interaction between a Fluid Star and a Kerr Black Hole in Circular Orbit

, 1999
We present a semi-analytic study of the equilibrium models of close binary systems containing a fluid star (mass $m$ and radius $R_0$) and a Kerr black hole (mass $M$) in circular orbit.

Radial deformation of the earth by oceanic tidal loading [PDF]

A high-degree spherical harmonic series is used to compute the radial deformation of the Earth by oceanic tidal loading. By exploiting fast numerical transforms, this approach is found to be much more efficient, but no less accurate, than the traditional

Tidally Modulated Glacial Slip and Tremor at Helheim Glacier, Greenland

Geophysical Research Letters
Numerical modeling of ice sheet motion and hence projections of global sea level rise require information about the evolving subglacial environment, which unfortunately remains largely unknown due to its difficulty of access.
