Triangular latt ice Electromagnetic Band-Gap (EBG) St ructure in the ground plane is used in the design of a Triangular Microstrip Patch Antenna (TMPA) Array to improve its bandwidth. The patch elements are equilateral t riangular in shape. The Equilateral Triangular Microstrip Patch Antenna (ETMPA) Array design has four patch elements in 2×2 form with ground plane having circular cutouts formi...

introduction: multileaf collimator (mlc) is state of the art among the radiation field shaping systems for conformal radiotherapy techniques. some advantages of this system are as follow: reduction of treatment time, higher precision in conforming the radiation field to the projection of the target volume and lowering the chance of errors made by technologists. the purpose of this research was ...

Background: Maxillary sinuses have reportedly survived mass disasters despite the skull and other bones being severely damaged. Forensic odontology relies heavily on radiography to identify individuals. The largest earliest form among paranasal is maxillary sinus. In order skeletal remains determine gender, sinus has been performed. AIM: To shape, height width of air their possible corelation g...

Surface morphology of thick diamond films was investigated using scanning electron microscopy (SEM). The dissociation of [1 1 1} faces into {1 1 0} faces is positively confirmed by the geometrical consideration of the crystal shapes, such as the V-shaped penetration twins and some other unusual crystal shapes. Growth mechanisms of the diamond rLl 1 1} and {1 1 O} faces are discussed. PACS: 81.0...

The use of corrugated webs in steel beams has become one the most practical ways to increase efficiency resisting loads, natural frequencies, and their resulting displacements. Such a practice benefit achieving same as with flat web greater thickness. Consequently, effect types on flexure mode shapes frequencies been investigated by analyzing 23 using finite element (FE) numerical analysis tech...

Abstract In this paper, multi-objective optimization (MOO) of Al2O3-water nanofluid flow in microchannel heat sinks (MCHS) with triangular ribs is performed using Computational Fluid Dynamics (CFD) techniques and Non-dominated Sorting Genetic Algorithms (NSGA II). At first, nanofluid flow is solved numerically in various MCHS with triangular ribs using CFD techniques. Finally, the CFD data will...

introduction: this  research was done to comparison  directionality of drawing fixed shapes in preschoolers and primary school according to role of  handedness.   materials and methods:  in this research causality – comparison, 160 children (80 girls and 80 boys) with mean age of 7/96 in preschool and primary school selected with randomly cluster sampling. the tests were used , handedness quest...

BACKGROUND Various physical parameters, including substrate rigidity, size of adhesive islands and micro-and nano-topographies, have been shown to differentially regulate cell fate in two-dimensional (2-D) cell cultures. Cells anchored in a three-dimensional (3-D) microenvironment show significantly altered phenotypes, from altered cell adhesions, to cell migration and differentiation. Yet, no ...

Abstract Nuclear deformations are fundamentally important in nuclear physics. We recently developed a multidimensionally constrained relativistic Hartree–Bogoliubov (MDCRHB) model, which all multipole respecting the V 4 symmetry can be considered self-consistently. In this work we extend model by incorporating angular momentum projection and parity to restore rotational symmetries broken mean-f...
