Triple staining with fluorochromes (DA/DAPI/CMA) and C-banding were used to characterize the composition of Pseudonannolene strinatii heterochromatin. C-banding showed C+ bands of different labeling intensity on chromosomes 1 and 2 in some cells. Fluorochrome staining revealed DAPI+ regions corresponding to the C-banding pattern, indicating that the heterochromatin of this species is abundant i...

This paper describes a novel technique for the very efficient and accurate computation of the coupling integrals of waveguide step discontinuities between arbitrary cross section waveguides. This new technique relies on solving the Integral Equation (IE) that provides the well-known Boundary Integral – Resonant Mode Expansion (BI-RME) method by the Nyström approach, instead of using the traditi...

The results from prior studies on the effectiveness of virtual teams (VTs) are ambiguous and show that few studies have built upon previous findings to build a substantiated body of work. In this article, the authors attempt to remedy this by performing a meta-analysis on VT research. Powell et al.’s (2004) framework of VTs is used as a prototype and twelve variables and their relationships ide...

This chapter presents a systematics of chat interaction. Online chats are advantageous sites for examining the organization of social interaction as achieved through computer-mediated communication. Chats differ from talk-in-interaction since the composition and visual inspection of text and graphical objects by any given actor is not observable by other participants. These structural constrain...

Crop plants suffer severe yield losses due to the significant damages caused by aphids. RNA interference (RNAi) technology is a versatile and environmentally friendly method for pest management in crop protection. Transgenic expressing siRNA/dsRNA non-transformative methods such as spraying, microinjection, feeding, nanocarrier-delivery-mediated RNAi approach have been successfully applied agri...

nanocrystalline zinc oxide (zno) powders with different morphology have been successfully synthesized by using different surfactants such as cetyl trimethyl ammonium bromide (ctab), sodium dodecyl sulphate (sds), and tri ethanol amine (tea) via hydrothermal method. the products were characterized by means of powder x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electr...
