Karyotype analysis of seven species of the tribe Lophiohylini (Hylinae, Hylidae, Anura), with conventional and molecular cytogenetic techniques
(Pensoft Publ, 2012-01-01)
Few species of the tribe Lophiohylini have been karyotyped so far, and earlier analyses were performed mainly with standard staining. Based on the analysis of seven species with use of routine banding and molecular cytogenetic ...

A flourescent probe study of the effect of size on the properties of dioctadecyldimethylammonium chloride vesicles
(1988)
Fluorescence techniques are used to study the effect of size on the properties of dioctadecyldimethylammonium chloride vesicles. The solubilization site and the deactivation rates of excited pyrene by bromide counterions ...
Surface area of ferrihydrite consistently related to primary surface charge, ion pair formation, and specific ion adsorption
(2020-01-20)
The specific surface area (SSA) of metal oxides is pivotal for scaling of surface phenomena. For ferrihydrite (Fh), the SSA can be assessed by probing the surface with ions that specifically adsorb (e.g. protons or phosphate). ...
Characterization of alpha thalassemic genotypes by multiplex ligation-dependent probe amplification in the Brazilian population

Time stability of soil water storage measured by neutron probe and the effects of calibration procedures in a small watershed
(ELSEVIER SCIENCE BV, 2009)
The knowledge of soil water storage (SWS) of soil profiles is crucial for the adoption of vegetation restoration practices. With the aim of identifying representative sites to obtain the mean SWS of a watershed, a time ...
Studies of current sheath evolution in a small plasma focus device
(IET, 1996)
We present preliminary time and space resolved studies of current sheath formation in Plasma Focus discharges, using a novel array of non invasive magnetic field probes. The experiments are performed in a Mather type plasma ...
