The Tidal Evolution of Local Group Dwarf Spheroidals
, 2007 (Abridged) We use N-body simulations to study the evolution of dwarf spheroidal galaxies (dSphs) driven by galactic tides. We adopt a cosmologically-motivated model where dSphs are approximated by a King model embedded within an NFW halo.

Efficient integration of the variational equations of multi-dimensional Hamiltonian systems: Application to the Fermi-Pasta-Ulam lattice [PDF]
, 2011 We study the problem of efficient integration of variational equations in multi-dimensional Hamiltonian systems. For this purpose, we consider a Runge-Kutta-type integrator, a Taylor series expansion method and the so-called `Tangent Map' (TM) technique ...

Diablo Canyon power plant site ecological study Quarterly Report no. 6; October 1 - December 31, 1974 [PDF]
, 1974 During the period October 1 - December 31, 1974, a total of six permanent subtidal stations and ten random intertidal stations were surveyed. Red tides and rough seas limited both the commerical abalone and sea urchin fishery activities. Most activity

Effects of the Planar Galactic Tides and Stellar Mass on Comet Cloud Dynamics
, 2009 We report the first results of a research program to explore the sensitivity of the orbits of Oort cloud comets to changes in the strength of the Galactic tides in the plane of the disk and also to changes in the mass of the host star.

The formation of CDM haloes II: collapse time and tides [PDF]
, 2014 We use two cosmological simulations of structure formation in the LambdaCDM scenario to study the evolutionary histories of dark-matter haloes and to characterize the Lagrangian regions from which they form. We focus on haloes identified at redshift z_id=

Potential environmental impact of tidal energy extraction in the Pentland Firth at large spatial scales : results of a biogeochemical model [PDF]
, 2016 A model study was carried out of the potential large-scale (> 100 km) effects of marine renewable tidal energy generation in the Pentland Firth, using the 3-D hydrodynamics–biogeochemistry model GETM-ERSEM-BFM.

Fish Kill Incidents and Harmful Algal Blooms in Omani Waters
Journal of Agricultural and Marine Sciences, 2011 Red tide, one of the harmful algal blooms (HABs) is a natural ecological phenomenon and often this event is accompanied by severe impacts on coastal resources, local economies, and public health.
