the nitrite ® nitro isomerization in nitritopentaamine cobalt (iii) halides has been known. in this paper, the effect of the size of the counter ions (noncoordinated groups) on the rate of isomerization in nitritopentaamine cobalt (iii) halides, is reported. the rate of isomerization is decreased by increasing the size of the counter ions. this decrease is explained on the basis of steric inter...

Pharmaceutically active compounds (PhACs), including prescription drugs, over-the-counter medications, drugs used in hospitals and veterinary drugs, have been found throughout the water cycle. A desk study was initiated by the Global Water Research Coalition to consolidate a uniform selection of such compounds in order to judge risks of PhACs for the water cycle. By identifying major existing p...

Many medicinal herbs and pharmaceutical drugs are therapeutic at one dose and toxic at another. Interactions between herbs and drugs may increase or decrease the pharmacological or toxicological effects of either component. Synergistic therapeutic effects may complicate the dosing of long-term medications eg, herbs traditionally used to decrease glucose concentrations in diabetes1 could theoret...

A comparison between a bit-level and a conventional VLSI implementation of a binary neural network is presented. This network is based on Correlation Matrix Memory (CMM) that stores relationships between pairs of binary vectors. The bit-level architecture consists of an n m array of bit-level processors holding the storage and computation elements. The conventional CMM architecture consists of ...

Consumption of over-the-counter drugs or medicinal products in Turkey has been increasing following Turk-ish legislation on the classification of medicinal products in 2005, which regulates the marketing of over-the-counter drugs (Turkish Pharmacists' Association 2009). Moreover, many international pharmaceutical products are easily obtained via suppliers on the Internet (Mor-ris and Avorn 2003...
