Levels of adenine nucleotides, inorganic phosphate, starch and apyrase were measured during the growth of Solanum tuberosum tuber. The data obtained from potatoes sown in summer were compared with the data already reported ...

2,4‐Dihydroxy‐7‐methoxy‐1,4‐benzoxazin‐3‐one (DIMBOA), the main hydroxamic acid isolated from maize extracts, increased the mortality of Schizaphis graminum when fed in artificial diets. Electrically‐monitored feeding ...

The aerial parts of Aphyllocladus denticulatus afforded, in addition to some widespread compounds, six 5-methylcoumarin derivatives isolated previo. © 1988.

Deuterium quadrupole splittings from the aromatic ring of a series of linear N-alkylpyridinium-d5 ions, with alkyl chains from 1 to 16 carbon atoms, were measured using 2H-NMR spectroscopy. The pyridinium ions, 10% deuteriated ...

Uridine 5′-diphosphate-glucose (UDP-Glc) is transported into the lumen of the Golgi cisternae, where is used for polysaccharide biosynthesis. When Golgi vesicles were incubated with UDP-[3H]Glc, [3H]Glc was rapidly transferred ...

In this paper we consider the study of standing wave solutions for a nonlinear Schrödinger equation. This problem reduces to that of finding nonnegative solutions of ε2Δu - V (x) u + (Latin small letter esh) (u) = 0 in Ω. ...

A symmetry adapted formalism to evaluate the vibronic intensities induced by the ungerade vibrational modes in centrosymmetric coordination compounds of the rare earths is put forward and applied to several selected ...

Thirteen alkaloids were identified from the stem-bark of Erythroxylum lucidum by GC-MS. Seven of these have not been reported previously in the genus Erythroxylum. Most of them are precursors or intermediates in the ...

We study the propagation of electrons (or excitations) through a one-dimensional tight-binding chain in the simultaneous presence of nonlinearity and diagonal disorder. The evolution of the system is given by a disordered ...
