A combinatorial library of 15,536 cyclic decapeptide analogues of tyrocidine A and gramicidin S was prepared on photocleavable TentaGel beads. The beads were photolyzed without solvent, and spread onto an agar plate inoculated with bacterial lawn. Clear zones were formed around beads carrying antimicrobially active peptides such as E18 c(kVOrnLfThiYOrnLq), which inhibited growth of B. subtilis ...

A microchannel plate (MCP)/phosphor screen assembly has been used to destructively measure the radial profile of cold, confined antiprotons, electrons, and positrons in the ALPHA experiment, with the goal of using these trapped particles for antihydrogen creation and confinement. The response of the MCP to low energy (10-200 eV, <1 eV spread) antiproton extractions is compared to that of electr...

A reaction diffusion system with time delay is proposed for virus spread on bacteria immobilized on an agar-coated plate. The delay explicitly accounts for a virus latent period of fixed duration. An interval of possible spreading speeds for virus infection is established, and traveling wave solutions are shown to exist. Linear determinacy of spreading speed breaks down for some parameter values.

In this study the sensorial performances of a four-channel quartz crystalmicrobalance implemented on a single quartz plate are reported and compared with those offour independent quartz crystal microbalances. Particular attention has been devoted to bothcross talk in responses and sensor sensitivity. A recently synthesized nanostructuredpolymer, poly[phenylacetylene-(co-2-hydroxyethyl methacryl...

White superficial onychomycosis is less common than distal subungual onychomycosis and occurs when certain fungi invade the superficial layers of the nail plate directly. Later, the infection may move through the nail plate to infect the cornified layer of the nail bed and hyponychium. It can be recognized by the presence of welldelineated opaque “white islands” on the external nail plate, whic...

Pseudocypretta Klie, 1932 is one of the few species that spread in aquatic environments; for the first time the genus Pseudocypretta was recorded from Iraq. The samples were collected in August 2004, Al -Hindiyah, Karbala Governorate (32°32'43.18"N, 44°13'24.97"E). Pseudocypretta maculata Klie, 1932, was recorded for the first time from Iraq. Some taxonomic characteristics were relied upon, suc...

AIM This study aimed at investigating the microbial contamination of mobile phones in a hospital setting. METHODS Swab samples were collected from 40 mobile phones of patients and health care workers at the Alexandria University Students' Hospital. They were tested for their bacterial contamination at the microbiology laboratory of the High Institute of Public Health. Quantification of bacter...

In situ fracture study of a Cu/Al composite laminate was discussed via the observation of scanning electron microscope (SEM). The experimental test was carried out by a modified miniature tensile device. With the aid of the SEM’s sample stage and a wedge block, the profile morphology of the specimen was observed. The substrate layer (1060 aluminum) and the plate layer (C11000 copper) of the spe...
