BACKGROUND Human milk possesses bacteriostatic properties, largely due to the presence of immunological proteins. Heat treatments such as Holder pasteurization reduce the concentration of immunological proteins in human milk and consequently increase the bacterial growth rate. This study investigated the bacterial growth rate and the immunological protein concentration of ultraviolet (UV-C) irr...

This paper looks at William Holder's "Elements of Speech" [1] from the perspective of modern phonetic and phonological literature. The structure of this presentation, first touching on general linguistic concepts, follows the three principal stages of speech production: respiration/air stream mechanism, phonation, and articulation. Holder's rendition of speech perception is discussed in conjunc...

In this research, two new methods that improve the drawing depth of deep-drawing processes have been introduced. In the first technique, by creating ridges on the punch surface, the stress concentration is decreased on the blank near the punch edge, in turn increasing the drawing depth. The second method is based on the principle of reducing resistant force in the flange area between the die, t...

Most wireless systems receive a license that gives them exclusive access to a block of spectrum. Exclusivity guarantees adequate quality of service, but it also leads to inefficient use of spectrum. Even when the license holder is idle, no other device can use the spectrum. This paper explores an alternative paradigm for secondary access to spectrum, where a secondary device can transmit when a...

in the present study, the potential of a bacterial consortium of enterobacter cloacae and pseudomonas sp. (ercppi-2) for microbial enhanced oil recovery was investigated. various mechanisms of enhanced oil recovery (eor) as a result of using ercppi-2 and its metabolic products were studied in detail. the obtained results showed that under simulated reservoir conditions, interfacial tension redu...

During the last decade extensive research has been made at Lund University, Sweden, on a lean premix (prevaporize) combustion concept with burnt gas recirculation and a metallic flame holder. From this concept a new lean premixed natural gas combustion chamber with internal combustion gas recirculation (CGR) has been developed for the V160/SOLO 161 Stirling engines. This combustor has ultra-low...
