The possible periodic structure of the scattering amplitude and its dependence from number of the additional dimensions are analyzed. The effects of the gravitational hadron form factors obtained from the hadron generalized parton distributions (GPDs) on the behavior of the interaction potential and the...
By this we find gravitational theories for all carrollian, galilean, and aristotelian counterparts of the lorentzian theories. In order to define a nondegenerate bilinear form for each of the theories, we introduce (not necessarily central) extensions of the original kinematical algebras. Using the ...
resulting in multiple images of the exploding star. This phenomenon is called gravitational lensing. Gravitationally lensed supernovae offer astronomers a unique way to calculate the Hubble
To ensure the existence of a well defined linearized gravitational wave equation, we show that the spacetimes in the so-called “Einstein–Gauss&
Time variation of Newtonian gravitational constant, $G$, is studied in the model universe with variable space dimension proposed recently. Using the Lagrangian formulation of these models, we find the effective gravitaional constant as a function of time. To compare it with observational data, a ...
and ligaments, which keeps the mandible against gravitational forces.10,17 The Variability of VDR The mandibular physiologic rest position (MPRP) has been considered by some researchers to be naturally established and remain constant throughout life regardless of the presence or absence of the teeth...
A difficulty with the acceptance of these ideas at the time was a lack of both experimental implications and a quantum description of gravitational dynamics. Today, one of the most striking requirements of modern string theory, which incorporates both gauge theories and gravitation, is that there ...
Live loads are also of different types for different structures although mechanically of the same nature which is to cause stress. For example, live loads for building structures are primarily vertical gravitational force of the occupants while for bridge structures they are primarily traffic loads, ...

with f the friction factor [unitless], d p the pipe diameter [L], g the gravitational acceleration [LT−2], and Δl p the length of pipe [L]. The friction factor is approximated for laminar conditions with the Hagen-Poiseuille equation and for turbulent flow with the Colebrook-White eq...
