The JCMT-CSO single-baseline interferometer was the first to demonstrate phase correction using the 183 GHz line, using equipment built by Martina Wiedner, Richard Hills and colleagues. Only a limited quantity of data were gathered but the results (ALMA memo 252) were encouraging and suggested that even an uncooled system could provide effective phase calibration at submillimetre wavelengths. S...

This document outlines the various quantities that will need to be measured or taken into account in order to collect and calibrate ALMA data. It is an update of Chapter 3 of the old Project Book, and supersedes it. Traditionally, “calibration” has often been thought of as strictly a postprocessing exercise in radio interferometry, essentially only involving things done to data after it has bee...

Abstract The smart healthcare system (SHCS) facilitates the process with widespread use of medical data through internet things (IoMT). Widespread data, especially images can also lead to privacy issues. Traditional encryption algorithms address some problems; however, they cannot deter redistribution decrypted content. To prevent content from being used illegally, paper proposes a combination ...

-The magnetic heat capacity of Gol-,MnxC12.2H20 with competing exchange interactions has been observed. A characteristic broad maximum appears around 4.5 K for x = 0.46 : nearly half of the magnetic entropy remains in the temperature region above 4.5 K. These thermal properties are discussed in comparison with other glassy systems.

The Atacama Large Millimeter Array (ALMA) is a joint project between North America, Europe and Japan. ALMA is an aperture synthesis radio telescope consisting of 50 12-meter antennas located at an elevation of 5,000 meters in Llano de Chajnantor, Chile. These antennas will operate at frequencies ranging from 31.3 GHz to 950 GHz. The antennas can be moved and placed in different configurations, ...

The story of how Alma-Ata and Primary Health Care gained the attention of the world’s health leadership must be seen as one of the most intriguing in the history of health and development. The postcolonial years in the developing world saw health care that was largely hospital-based and curative in its orientation, whichmeant, of course, that most people who needed health care had little or no ...

Accepted 26 February 1997 Abstract Objective-To evaluate the use of urinary mercapturic acids as a biomarker of human exposure to allyl chloride (3chloropropene) (AC). During three regular shut down periods in a production factory for AC, both types of variables were measured in 136 workers involved in maintenance operations. Methods-Potential airborne exposure to AC was measured by personal ai...
