The internal strain in cyclic amides are explained as a factor of resonance that are effected on the bond length C-N  and are a major factor of rates of hydrolysis. The cyclic amides in this study are optimized by Gaussian program and the bond length of C-N in the rings are studied by HF/6-31G*.

In the present investigation the applicability of various topological indices are tested for the QSPR study on 80 amino acids derivatives. Relationship between the Randic' (1X), Balaban (J), Szeged (Sz), Harary (H), Wiener (W), Hyper-Wiener (WW) and Wiener Polarity (WP) indices to the thermodynamic Properties such as thermal energy Eth (J/mol) and heat capacity (CV J/mol. K) of amino acids is r...

We have reported several changes in neonate or adult offspring after the maternal use of whole flaxseed or its components. However, it is unknown the use of higher oil intake in the neonatal period. Here we evaluated the effects of high maternal intake of flaxseed oil during lactation upon milk and body composition in male and female offspring. Lactating rats were divided into: (1) control (C, ...

Energy load forecasting for optimization of chiller operation is a topic that has been receiving increasing attention in recent years. From an engineering perspective, the methodology designing and deploying system should take into account several issues regarding prediction horizon, available data, selection variables, model adaptation. In this paper these are parsed to develop neural forecast...

The methamphetamine has been studied theoretically at the MP2 [1]/6-31G[2] level in gas phase.Methamphetamine has been investigated Via NMR, Frequencies Calculation and NBO analysis. Thestructure of methamphetamine was designed primarily using of Chem. Bio Draw and it geometry hasbeen optimized at the MP2/6-31G computational level. The present work consists the study of themethamphetamine repor...

Bound energy levels and properties of the Cl(2P)-HF complex were obtained from full three-dimensional (3D) calculations, with the use of the ab initio computed diabatic potential surfaces from the preceding paper and the inclusion of spin-orbit coupling. For a better understanding of the dynamics of this complex we also computed a 2D model in which the HF bond length r was frozen at the vibrati...

Using the recently introduced maximum overlap method and Hartree–Fock Perturbation Theory (HFPT), we compute Hartree–Fock (HF) wavefunctions for triplet 1s ns states of the helium atom. Comparison with near-exact results from Nakatsuji’s free ICI method reveals that HF theory provides a simple route to accurate energies of these Rydberg states, especially for large n. © 2009 Wiley Periodicals, ...

This paper is concerned with the problem of recursive system identification using nonparametric Gaussian process model. Non-linear stochastic system in consideration is affine in control and given in the input-output form. The use of recursive Gaussian process algorithm for non-linear system identification is proposed to alleviate the computational burden of full Gaussian process. The problem o...
