BACKGROUND Diamagnetic levitation is a technique that uses a strong, spatially varying magnetic field to simulate an altered gravity environment, as in space. In this study, using Streptomyces avermitilis as the test organism, we investigate whether changes in magnetic field and altered gravity induce changes in morphology and secondary metabolism. We find that a strong magnetic field (12T) inh...

The equilibrium of dense plasma in a gravity field and problem of a gravity-induced electric polarization in this matter are discussed. The calculation for metals performed before shows that both-the gravity-induced compressive strain and the gravity-induced electric field-are inversely proportional to their Young moduli. The calculation for high dense plasma, where Young modulus is equal to ze...

The aim of this paper is to investigate the influences of rotation, magnetic field, initial stress, and gravity field on Rayleigh waves in a homogeneous orthotropic elastic medium. The government equations is solved by Lame’s potential and obtained the frequency equation which determines the velocity of Rayleigh waves, including rotation, initial stress, gravity field, and magnetic field, in a ...

the earth’s gravity field dedicated missions, champ, grace and goce have opened up a new era for the study of the earth’s gravity field. the missions measure different functionals on the earth’s gravitational potential which are represented in terms of the stokes coefficients or the so-called geopotential models. the mapping process of the observations into the coefficients is called recovery o...

39 This paper describes the computation and analysis of the Earth's short-scale gravity field 40 through high-resolution gravity forward modelling using the Shuttle Radar Topography 41 Mission (SRTM) global topography model. We use the established residual terrain modelling 42 technique along with advanced computational resources and massive parallelisation to 43 convert the high-pass filtered ...

This is a semi-technical presentation of the succession of events that led Einstein to formulate his theory of general relativity. We present an overview of the field of relativistic astrophysics and motivate the study of compact objects (such as neutrons stars and black holes) as strong-field gravity probes for testing possible modifications to general relativity. 1 A PANORAMA OF PHYSICS BEFOR...
