Detemination of fungicide residues in grape by GC/MS.

, 2012
The extensive use of pesticides in modern farming on fruit and vegetables has posed risks to public health and environment. Pesticide residues can be found even when they are applied in accordance with good agricultural practices. This paper deals with the analysis residues of three fungicides (benalaxyl, dimethomorph, tetraconazole) by chromatographic

Multi‐Solvent Suppression Ultrafast 2D COSY for High‐Throughput Wine Screening

Magnetic Resonance in Chemistry, EarlyView.
An interleaved ultrafast COSY with multi‐solvent suppression was developed for wine analysis to overcome limitations often associated with 1D 1H NMR (signal overlap) and conventional 2D NMR (long acquisition times) methods. Within an acquisition time of ~20 min, it revealed hidden metabolite peaks and cross peaks for improved annotation and ...

Calibration‐Free GRAPE pTx Pulses for Homogeneous Spatial‐Selective Excitation at 7T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Extend the universal pulse GRAPE formalism to pulses with a defined spectral response, and apply the concept to spatial selection. Methods We added Bloch simulations at several frequencies for each voxel to the pulse calculation to create universal spectrally‐selective GRAPE pulses.

Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

Nordic Journal of Botany, EarlyView.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately
