Frequency Stability of 1×10 in a Compensated Sapphire Oscillator Operating above 77 K
We report on tests of a compensated sapphire oscillator (CSO) which shows frequency-stable operation at temperatures above 77 K[1]. The frequency stability for this oscillator shows an apparent flicker floor of 7.5×10 for measuring times between 3 and 10 seconds, and stability better than 2×10 for all measuring times between 1 and 100 seconds. These values are approximately the same as for the ...
متن کاملAn Investigation into Air Ejector with Pulsating Primary Flow
The article deals with pneumatic and hot wire anemometry measurement on subsonic axi-symmetric air ejector. Performances of the ejector with and without pulsations of primary flow are compared, measuring of characteristic pressures and mass flow rates are performed and ejector efficiency is evaluated. The pulsations of primary flow are produced by a synthetic jet generator, which is placed in t...

متن کاملInvestigation of Antimicrobial Effect of Biebersteinia multifida on White Cheese Stored at Refrigerator Temperature
Introduction: In recent years, food manufacturers have taken a lot of attention to the use of natural preservatives instead of chemical preservatives in their products, which has led consumers to prefer to use processed food without preservatives or even with natural preservatives. The aim of the present study was to investigate the antibacterial effect of ethanolic extract of Biebersteinia mul...
متن کاملPressure-induced transformations in LiCl-H2O at 77 K.
A systematic study of the properties of high-density amorphous ice (HDA) in the presence of increasing amounts of salt is missing, especially because it is challenging to avoid ice crystallization upon cooling the pressurized liquid. In order to be able to study HDA also in the presence of small amounts of salt, we have investigated the transformation behaviour of quenched aqueous LiCl solution...
