We report for the first time that polydiacetylenes (PDAs) can be alternatively prepared via a plasma induced polymerization process. The degree of polymerization and colorimetric transitions could be manipulated by controlling the power of plasma radiofrequency, exposure time and by using an acrylic mask, resulting in their great potential for patterning applications.

Abstract Nickel induced genotoxic effect on Allium cepa root meristem was evaluated after treating onion root tips with various concentrations of NiCl2 in different time intervals. Mitotic index was higher (9.87 ± 1.96) at initial concentration of 10μg/l in three time i...

The interaction of space and time affects perception of extents: (1) the longer the exposure duration, the longer the line length is perceived and vice versa; (2) the shorter the line length is, the shorter the exposure duration is perceived. Previous studies have shown that space-time interactions in human vision are asymmetrical; spatial cognition has a larger effect on temporal cognition rat...

If several items are associated with a common cue, the cued recall of an item is often supposed to decrease as a function of the increase in strength of its competitors' associations with the cue. Evidence for such a list-strength effect has been found in prior research, but this effect could have been caused both by the strength manipulations and by retrieval-based suppression, because the str...

Cryopreservation and sexing of embryos are integrated into commercial embryo transfer technologies. To improve the effectiveness of vitrification of in vitro produced buffalo embryos, two experiments were conducted. The first evaluated the effect of exposure time (2 and 3 min) and developmental stage (morula and blastocysts) on the viability and development of vitrified buffalo embryos. Morphol...

Background: Recently, it has been found that exposure of sperm to PVP may cause submicroscopic changes in sperm structure and the sperm nucleus. The PVPinduced nuclear damage may have been due to breakdown of sperm membranes. Consequently, it is probable that exposure of sperm to PVP may impair embryo development. There are apparently no detailed reports regarding the specific effects of PVP on...
