Simulation of a New Process Design to Fabricate a Rectangular Twist Waveguide Using Extrusion and a Twist Die
The aim of the present study is to determine the feasibility of making a rectangular twist waveguide used to rotate electromagnetic waves. For this purpose, the process of fabricating an aluminum rectangular twist waveguide was simulated by making use of finite element method and Deform software. The optimum length and angle of the twist die for manufacturing a twist waveguide with inner cross ...
متن کاملEffect of twist on the performance of tire cord yarns
The effect of twi st on the performance of polyethylene naphthal ate, dimensionally stable polyester and high-tenacity polyester cord yarns has been studied. h is observed that the twi st has a very important effect on the tensile properties, creep properties and fracture mechani sm. An increase in the twi st leve l increases breaking elongation and creep rate but decreases break ing strength. ...
متن کاملThe evolution of the nonsinglet twist-3 parton distribution function
The twist three contributions to the Q2-evolution of the spin-dependent structure function g2(xBj , Q 2) are considered in the non-local operator product approach. Defining appropriate twist three distribution function we derive their evolution equation for the nonsinglet case in leading order approximation. In the limit xBj → 1 as well as in the large Nc limit we confirm the result that the ev...
متن کاملTWIST 1 ( twist homolog 1 ( Drosophila ) )
The 20.9 kDa protein encoded by TWIST1 gene is a highly conserved transcription factor that belongs to the family of basic helix-loop-helix (bHLH) proteins. In vertebrates, it is involved in embryonic development through the regulation of epithelial-mesenchymal transitions (EMT) during neural crest migration, also it regulates mesoderm determination, myogenesis, and morphogenesis (Hebrok et al....
متن کاملHigher Twist Distribution Amplitudes of Vector Mesons in QCD: Twist-4 Distributions and Meson Mass Corrections
We present a systematic study of twist-4 light-cone distribution amplitudes of vector mesons in QCD, which is based on conformal expansion. The structure of meson mass corrections is studied in detail. A complete set of distribution amplitudes is constructed, which satisfies all (exact) equations of motion and constraints from conformal expansion. Nonperturbative input parameters are estimated ...
