Ultrasound-assisted synthesis of benzophenones by Stille cross-coupling reactions. Optimization via experimental design
(Elsevier, 2013-01-01)
A series of diaryl ketones have been synthesized in moderate to excellent yields through the selective cross-coupling reaction of benzoyl chlorides with arylstannanes using a sonochemical variation of the Stille coupling. ...
Experimental determination of multiple ionization cross sections in Si by electron impact
(American Physical Society, 2015-12)
The thin sample method is often used to experimentally determine ionization cross sections, especially when focusing on the low overvoltage region. The simplicity of the formalism involved in this method is very appealing, ...
Talking about barley and slats in crossing

Crossed leg sign is associated with severity of unilateral spatial neglect after stroke
(2018-04-18)
Background: The crossed leg sign in patients with right hemisphere stroke is thought to be associated with perceptual disorders, such as unilateral spatial neglect (USN). The aim of this study was to compare the crossed ...
Porosity effects on the neutron total cross section of graphite
(Elsevier Science, 2010-01)
For subthermal neutron energies, polycrystalline graphite shows a larger total cross section than predicted by existing theoretical models. In order to investigate the origin of this discrepancy we measured the total cross ...
Evaluation of cross-reactivity to Taenia hydatigena and Echinococcus granulosus in the enzyme-linked immunoelectrotransfer blot assay for the diagnosis of porcine cysticercosis
(BioMed Central, 2019)
BACKGROUND: Taenia solium is an important zoonotic parasite that infects humans as definitive host (taeniasis) and pigs as intermediate host (cysticercosis). Serological diagnosis of porcine cysticercosis is limited to ...
Cytogenetic and morphologic approaches of hybrids from experimental crosses between Triatoma lenti Sherlock & Serafim, 1967 and T. sherlocki Papa et al., 2002 (Hemiptera: Reduviidae)
(Elsevier B.V., 2014-08-01)
The reproductive capacity between Triatoma lenti and Triatoma sherlocki was observed in order to verify the fertility and viability of the offspring. Cytogenetic, morphological and morphometric approaches were used to ...
Experimental determination of L X-ray fluorescence cross sections for elements with 45 < Z < 50 at 10 keV
(2014)
Synchrotron radiation at 10 keV was used to experimentally determine the Ll, La, LbI ,LbII , LgI and LgII fluorescence cross sections for elements with 45 < Z < 50, as part of an ongoing investigation at low energies. The ...
