CUSTR- A VHF phased array radar for observation of atmospheric dynamics and ionospheric plasma irregularities.

A VHF phased array radar for atmospheric dynamics observation is installed at the University of Calcutta, Kolkata. The Calcutta University Stratosphere-Troposphere Radar (CUSTR) operates at 53 MHz with 475 three sub-element Yagi-Uda antenna array. The CUSTR system is a high-power fully active phased array system with a dedicated 2 kW solid-state Transmit-Receiver Module (TRM) attached to each antenna, providing a total peak power of 950 kW with 47.

Dual-band dual-polarized sub-6 GHz phased array antenna with suppressed higher order modes.

This manuscript proposes a dual-band dual-polarized 64-element phased array antenna (PAA) with suppressed higher order modes (HoMs). Each array element is a microstrip patch structure with complementary split ring resonator (CSRR) loading, allowing for simultaneous dual-band and dual-polarization performance at 3.45 GHz and 3.

Osteochondroma at its rarest site.

Introduction: Osteochondromas usually arise from the metaphyseal region of the growing skeleton but extraskeletal cartilaginous tumors are rarest.

Case Report: A 65 year old woman presented with anterior knee pain and inability to flex her knee more than 90° since 1 year. Clinical examination and imaging studies revealed a nodular calcific mass in the anterior portion of the knee i.

A validated stability indicating rapid LC method for duloxetine HCl.

The present paper describes the development of a reversed phase liquid chromatographic (RPLC) analytical method for duloxetine HCl in the presence of its impurities and degradation products generated from forced decomposition studies. The drug substance was subjected to stress conditions of hydrolysis, oxidation, photolysis and thermal degradation. The degradation of duloxetine HCl was observed under acid hydrolysis.
