Calculation involving hydrogen-hydrogen(2) collisional cooling processes for use in astrophysics
… instance, in order to collapse into objects, the gravitational potential energy of primordial density fluctuations must be radiated away. The most abundant element in the universe is hydrogen, and cooling processes involving hydrogen are important in several contexts. To calculate the cooling, the …

Classical, quantum and numerical aspects of modified theories of gravity
… spin-0 particles. We derive the corresponding gravitational potential energy for the non-static case and show that the quantum correction of the local theory, which is in the form of a Dirac delta function, is smeared out in the non-local theory. It is also shown that the gravitational …

Rapid Middle to Late Miocene Slip Along the Zanskar Normal Fault, Greater Himalayan Range, NW, India: Constraints from Low-Temperature Thermochronometry
… channel flow mechanism and/or by an increase in gravitational potential energy as a consequence of a slab break-off event.

Multifaceted Understanding of Accreting Neutron stars and their Environments
… neutron stars peak in the X-rays, owing to gravitational potential energy loss as the accreting material falls under the strong gravitational well of the neutron star. The community has been utilizing X-ray timing and spectroscopy for decades to unravel the mysteries of these objects, with …

Contact angle hysteresis and the energy principle
… by minimizing the sum of the Helmholtz free energy and gravitational potential energy (or the total energy) of the system. This is the energy principle. Our model presumes that both the surface of the solid and the liquid/vapor interface can be generated by drawing normals through a curve in …

Mechanism of Hip Dysplasia and Identification of the Least Energy Path for its Treatment by using the Principle of Stationary Potential Energy
… a developed method for identifying the least energy path that the femoral head would follow during reduction. This is achieved by utilizing a validated computational biomechanical model that allows the determination of the potential energy, and then implementing the principle of stationary …

Contributions to the Study of Lithospheric Deformation and Seismicity in Stable Continental Regions
… topographic data was used to calculate the gravitational potential energy, and in turn the body stress and deviatoric stress for the region. This study also investigated how this deviatoric stress (or deviatoric strain) can be more accurately calculated on a spherical rather than a flat …

THE CLIMATIC, BIOTIC AND TECTONIC EVOLUTION OF THE PALEOGENE RENOVA FORMATION OF SOUTHWESTERN MONTANA
<p>The Renova Formation of southwestern Montana contains an important record of Paleogene floral, faunal, climate and tectonic change in the northern Rocky Mountains. The period between the end of the early Eocene and the early Oligocene (~49-32 Ma) was a time of rapid and far-reaching climate …

The Impact of Rolling Dynamic Compaction
… that towing speed quantifiably influenced the energy imparted into the ground, with towing speeds of 10-12 km/h found to be optimal. Targeted full-scale field trials were undertaken to quantify the depth of improvement that can be achieved using RDC. Field results were compared to a number of …

Aspects of mirrors and suspensions for advanced gravitational wave detectors
Gravitational waves were first predicted by Albert Einstein's Theory of general relativity, published in 1916. These waves are perturbations in the curvature of space-time. Indirect evidence of their existence has been obtained via observations of binary pulsar system inspirals by Hulse and Taylor. …

Development of an efficient fluid-structure interaction model for floating objects
… translation of the rigid body is governed by the gravitational force and the restoring force from Archimedes' principle. As the ship oscillates up and down, the gravitational potential energy is partially transferred to the radiated free-surface water waves, damping and eventually stopping the …
