I consider the next-to-leading high-energy cluster expansion of large-k double jet production in QCD, and I determine the corresponding one-loop quark and gluon impact factors for a self-consistent energy scale. The result shows that coherent angular ordering of emitted gluons holds for hard emission also, and singles out a scale which in essentially the largest virtuality in the process. Both ...

It is now well established that quantities such as energy dissipation, scalar dissipation and enstrophy possess huge fluctuations in turbulent flows, and that the fluctuations become increasingly stronger with increasing Reynolds number of the flow. The effects of this small-scale “intermittency” on various aspects of reacting flows have not been addressed fully. This paper draws brief attentio...

Increasing population growth and decreasing land ratio made it difficult for rural people of Bangladesh to maintain their livelihood. Especially the small-scale farmers find it trickier using their scarce resources. One House One Farm approach(OHOF) is designed to utilize the house and farm resources of the small- scale farmers to improve their livelihood. The focus of the study was to determin...

The present work mainly studies the free vibration of circular magneto-electro-elastic (MEE) nano-plates based on the Kirchhoff’s plate theory within the framework of nonlocal elasticity theory to account for the small scale effect. The MEE nano-plate studied here is considered to be fully clamped and subjected to the external magnetic and electric potentials. Using nonlocal constitutive relati...

   The main purpose of the present investigation is to analyze more comprehensively the size-dependent nonlinear free vibration response of multilayer functionally graded graphene platelet-reinforced composite (GPLRC) nanobeams. As a consequence, both of the hardening stiffness and softening stiffness of size effect are taken into consideration by implementation of the nonlocal str...

the uncontrolled spread of illegal artisanal small-scale gold mining (asm), popularly termed “galamsey” in ghana, has, for decades, impacted adversely upon water bodies, soils, wildlife, human health, and safety. a lack of understanding, however, of the types of galamsey, their operational attributes, and their relative impacts has unfortunately hindered an effective policy response despite num...

In this paper, Eringen’s nonlocal elasticity and Timoshenko beam theories are implemented to analyze the bending vibration for non-uniform nano-beams.  The governing equations and the boundary conditions are derived using Hamilton’s principle. A Generalized Differential Quadrature Method (GDQM) is utilized for solving the governing equations of non-uniform Timoshenko nano-beam for pinned-pinned...

This paper aims to investigate the pull-in phenomenon of functionally graded (FG) capacitive nanocantilevers subjected to an electrostatic force and thermal moment due to an applied voltage and thermal shock considering intermolecular force within the framework of nonlocal elasticity theory to account for the small scale effect. The FG nano-beam is made of mixture of metal and ceramic which the...
