The synthesis of 2-amino-5-substituted 1,3,4-oxadiazoles by the reaction of a 1-acyl-3-thiosemicarbazide with Pb3O4 is described. One of the procedures, namely the use of Pb3O4 in N,N-dimethylformamide, has some advantages over the earli... HL Yale,K Losee - 《Journal of Medicinal...
Mathematical Models of Complex Systems are generally formulated in terms of Traditional Differential Calculus (TDC), that is by means of linear and non-linear differential equations based on the well-known concept of derivative. Such a mathematical language, however, always introduces a "drift" betwe...
New selective, precise, and accurate methods are described for the determination of a ternary mixture containing drotaverine hydrochloride (I), caffeine (II), and paracetamol (III). The first method uses the first (D1) and third (D3) derivative spectrophotometry at 331 and 315 nm for the ...
On the basis of the quantum white noise theory we introduce the notion of creation- and annihilation-derivatives of Fock space operators and study the differentiability of white noise operators. We define the Hitsuda–Skorohod quantum stochastic integrals by the adjoint actions of quantum stochastic ...
This paper deals with automatic model identification in the analysis of pressure transients. The choice of the model, sometimes called diagnostic, is one of the first steps in the interpretation process, and it is important as it affects the values of the parameters deduced from the match. This...
PHTHALAMIDE DERIVATIVE PESTICIDE FOR AGRICULTURAL AND HORTICULTURAL APPLICATIONS WHICH COMPRISES SAID DERIVATIVE AND METHOD OF UTILIZING SAID PESTICIDE The present invention relates to a phthalamide derivative represented by general formula (I) or a salt thereof. [In the formulaX represents a halogen at...
Besides, the propyl sulfonamide tail occupied the small lipophilic pocket formed by an outward shift of the αC-helix and this might account for the selectivity of these inhibitors towards BRAFV600E (Fig. 12a) [83]. The X-ray crystal structure of compound 38 also revealed a head-to-...
By employing the tools of variational analysis, we provide new characterizations for subderivatives and subdifferentials of the dual gap functions for pseudo-monotone variational inequality problems (VIP) in R-n. Based on these, we give an exact expression of the largest global error bound constant...
Reaction of [Ru(p-cymene)Cl2]2 with [H7P8W48O184]33− (P8W48) in aqueous acidic medium results in the organometallic derivative [{K(H2O)}3{Ru(p-cymene)(H2O)}4P8W49O186(H2O)2]27− (1); in addition to the four {Ru(p-cymene)(H2O)} units, an unusual WO6 group with four...
While carrying out electron ionization (EI) mass spectrometric analysis on the 13C-labeled derivative, it was discovered that the formation of an ion with a peak at m/z 245.12 is the result of [CH 3CH 2O·] loss from the amino groups resulting from α-cleavage. This differs from ...
