this paper attempts to investigate the capability of the numerical finite element method for the removal of the regional effects from the observed gravity data from the dehnow anticline. from a geological point of view, the dehnow area is a part of the fars sedimentary basin south-east iran. the khamy formation and bangestan group are the oldest geological structures in the area that have outcr...

A bstract We give evidence that fully supersymmetric Anti-de Sitter vacua of extended supergravity with a residual gauge group containing an abelian factor cannot be scale separated as consequence the weak gravity conjecture. prove this for N = 2 and 8 we explain how our argument applies also to partially broken, but supersymmetry. finally discuss possible loopholes especially certain 1 models ...

We present the preferential filtering method for gravity anomaly separation based on Green equivalent-layer concept and Wiener filter. Compared to the conventional upward continuation and the preferential continuation, the preferential filtering method has the advantage of no requirement of continuation height. The method was tested both on the synthetic gravity data of a model of multiple rect...

in the present attempt, flow behavior and thermal convection of one type of nanofluids in a disc geometry was investigated using computational fluid dynamics (cfd). influence of gravity induced sedimentation also has been studied. the commercial software, fluent 6.2, has been employed to solve the governing equations. a user defined function was added to apply a uniform external magnetic field....

Conventional gravity separation process of iron mineral fines is not very effective. In present work Multi Gravity Separation (MGS) process has been studied. This study was performed on a low-grade iron ore namely goethiticlateritic ore (GLO) from Eastern India. Detailed mineralogical, physical and chemical characteristics of a goethiticlateritic iron ore showed that the sample contained porous...

detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. this distribution could be detected by different geophysical methods, especially gravity method. however, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. performance of the gravity technique co...
