Dipteran chromosomes: a simple method for obtaining high quality chromosomal preparations
(Indian Academy of Sciences, 2014-12)
For cytogenetic studies it is necessary to develop an efficient method of chromosome preparation with wellpreserved and dispersed chromosomes and little or no cell-wall debris. In this study, we describe a method for ...
Ultrasonic versus high-speed cavity preparation: Analysis of increases in pulpal temperature and time to complete preparation
(Mosby-elsevier, 2008-08-01)
Statement of problem. The use of ultrasonic tips has become an alternative for cavity preparation. However, there are concerns about this type of device, particularly with respect to intrapulpal temperatures and cavity ...

Dithiol-capped Cdse nanoparticle Fims prepared by a soft chemistry method.
(64th Annual Meeting of the International Society of Electrochemistry- Sep. 2013 Qro. Mex Symposium 06, 2013-09-13)
Bulk heterojunction solar cells require adequuate concentrations of the nanoparticulated n-type semiconductor within the polymeric matrix, but also a good interfacial interaction between the. Thiol and dithiol molecules ...
Spectrophotometric determination of dipyrone in pharmaceutical preparations by using chromotropic acid
(Elsevier B.V., 1999-09-30)
A spectrophotometric method for the determination of dipyrone in pharmaceutical preparations is proposed. This method is based on selective oxidation of dipyrone, in the presence of sulphuric acid, splitting off formaldehyde ...
