The descriptors computed by HyperChem® software were employed to represent the solubility of 40 drug molecules in supercritical carbon dioxide using an artificial neural network with the architecture of 15-4-1. The accuracy of the proposed method was evaluated by computing average of absolute error (AE) of calculated and experimental logarithm of solubilities. The AE (±SD) of data sets was 0.4 ...

Let G be a graph and let T be a tree with the same vertex set. Let e be an edge of T and Ae and Be be the vertex sets of the components of T obtained after removal of e. Let EG(Ae, Be) be the set of edges of G with one endvertex in Ae and one endvertex in Be. Let ec(G : T ) := max e |EG(Ae, Be)|. The paper is devoted to minimization of ec(G : T ) • Over all trees with the same vertex set as G. ...

Carum copticum is a grassy and annual plant which is believed to have several therapeutic effects, including anti-asthmatic properties. We have therefore studied the bronchodilatory and anticholinergic effects of 4 rnL aqueous extract (AE), 0.0 5 mL ethanol extract (EE), and 0.0 0 5 mL essential oil (EO) of Carum copticum and 1 rnL of a 5 mM solution of its main ingredient, thymol (T), in ...

The work presents a necessary and sufficient condition for the generalized AE-solution sets to interval linear systems of equations to be unbounded. The criterion requires solvability of one of the totality of 2 linear inequalities constructed from the initial interval system. It is shown that the problem of recognizing the boundedness of AE-solution sets is NP-complete in general.

AE monitoring from various types of stress corrosion cracking (SCC) has been conducted for the past 15 years in our laboratory. This paper discusses AE results of active-path dissolution-type SCC of austenitic stainless steel in chloride solution and fused salt, fluoride and polythionic acid solutions, brass in ammonia (Mattosson's solution), and carbon steels in nitrite solution. Transgranular...

  In this study we investigated the bronchodilatory and anticholinergic effects of the aqueous extract (AE), brewed extract (BE) and ethanol extract (EE) of Polygonum avicular in comparison with saline (S) on isolated tracheal chains of the guinea pig. Due to the probable confounding effect of ethanol in the EE, the effects of this extract were also compared with 96 % ethanol. None of the plant...

The alternating evolution (AE) system of Liu [27] ∂tu+ ∂xf(v) = 1 (v − u), ∂tv + ∂xf(u) = 1 (u− v), serves as a refined description of systems of hyperbolic conservation laws ∂tφ+ ∂xf(φ) = 0, φ(x, 0) = φ0(x). The solution of conservation laws is precisely captured when two components take the same initial value as φ0, or approached by two components exponentially fast when ↓ 0 if two initial st...
