Radio-astronomical observations are increasingly contaminated by interference, and suppression techniques become essential. A powerful candidate for interference mitigation is adaptive spatial filtering. We study the effect of spatial filtering techniques on radio-astronomical imaging. Current deconvolution procedures, such as CLEAN, are shown to be unsuitable for spatially filtered data, and t...

Background: Health care-associated infections (HAI) continue to be a significant global community health issue and concern patient safety despite progress in infection control strategies. Among the most often reported illnesses acquired hospitals are surgical site (SSI) (HAI). Methods: This prospective observational study was held various Surgical departments of Bakhtawar Amin Trust Teaching Ho...

We present the analysis of 445 high signal-to-noise spectra of the Si III triplet at 4553 Å, 4568 Å, 4575 Å of the lineprofile variable star ε Persei. The data were gathered during 14 consecutive nights and fully cover the orbital cycle of the binary. The orbital parameters that we derive from our data for the close binary are in full agreement with those found in 1995 by Tarasov et al. Our dat...

Text by Mitch Leslie [email protected] Diet ing yeast c lean house W hen a yeast cell hunkers down for hard times, it kicks its proteasomes out of the nucleus, as Laporte et al. show. The cell’s garbage disposal, the proteasome, digests proteins that are damaged or no longer needed. In dividing yeast, proteasomes in the nucleus help drive the cell cycle by demolishing regulatory proteins ...

INtrODuCtION The Clean Development Mechanism has been recognized as a force for the empowerment of women through its various methodologies. While these methodologies may not have started out to be gender-friendly per se, their application has improved women's lives and by extension the lives of their communities. This publication will highlight some of these gender-friendly methodologies, as we...

The interesting fact emerges that farm workers, not properly instructed in the cleansing of covered pails, were actually getting worse results with them than with open pails :? Buckets, open and covered, were washed by the farm hands with warm water and a cloth in accordance with the usual practice. The milk taken into the covered bucket contained many more bacteria than that taken into the ope...
