Abstract With the Foot Pedals and Accessories ability to focus and rotate the acoustic field in a given region while keeping the outside region unchanged, the acoustic concentrator and rotator has been developed for the versatile manipulations of acoustic wave.In this letter, we report the design of acoustic concentrator and rotator facilitated by

One of the most important problems that cotton knitted fabrics present during the manufacturing process is their dimensional instability, which needs to be minimised.Some of the variables that intervene in fabric shrinkage are related with its structural characteristics, use of fiber when producing yarn, the yarn count used or the dyeing process em

Objectives: CD4+CXCR5+ T cells have previously been established.However, their decreased frequency during tuberculosis (TB) disease is only partially understood.The aim of this study was to explore the depletion of CD4+CXCR5+ T cells in human TB.Methods: The frequency and function of CD4+CXCR5+ T cells were evaluated in active screenprotector TB (A

Abstract The design and analysis of an ultra wideband aperture antenna with dual-band-notched characteristics are presented.The proposed antenna consists of a circular ring exciting stub on the front side and a circular slot on the back ground plane.By utilizing a parasitic strip and a T-shaped stub on the antenna structure, two notched bands parfu
