Elimination of massive aggregation of nanoparticles in the sample of high ionic strength is knowall.blog a prerequisite for the sensitive analysis through a surface-enhanced Raman spectrometry (SERS).We present a system of silver colloid modification composed of two thiolated modifiers (3-mercaptopropionic acid and thiolated polyethylene glycol) bo
Dinoflagellates are haploid eukaryotic microalgae in which rapid proliferation causes dense blooms, with harmful health and economic effects to humans.The proliferation mode is mainly asexual, as the sexual cycle is believed to be read more rare and restricted to stressful environmental conditions.However, sexuality is key to explaining the recurre
The periodical cicadas of the genus Magicicada Davis, 1925 inhabiting eastern United States are characterized by a long juvenile period of 17 or 13 years and periodical mass emergence of adults.In this genus, only seven species are distinguished and are distributed into three species groups, Decim, Cassini and Decula.We performed comparative cytoge
Root growth and crop yield can be affected by chemical modifications of the soil profile owing to lime and gypsum applications.A field trial was carried out on a dystrophic Clayey Rhodic Hapludox at Ponta Grossa, PR, Brazil, aiming to evaluate lime (without or with incorporation into the soil) and gypsum effects on root growth, mineral nutrition an
A new blind channel estimation technique is proposed for space-time coded wideband CDMA systems using aperiodic and possibly multirate spreading codes.Using a dea eyewear decorrelating front end, the received signal is projected onto a subspace from which channel parameters can be estimated up to a rotational ambiguity.Exploiting the subspace struc
