one of the vague issues in relation to cases involving drug abuse is the necessity of determining the purity of drugs. gaps in related laws have created confusion for judges. some believe purity levels of drugs used by criminals must be considered in the processing of their cases as well as in their punishment. since the harsh processing sometimes involves death and life, the controversy is esp...

production ofdimethyl amino ethanol (dmae) and effective parameters on efficiency and purity of the chemical were studied in this article. dimethylation of ethanol amine using aqueous formaldehyde in the presence of formic acid was applied for production of dmae. results showed that four parameters such as outlet temperature of co2 gas, reflux temperature, reflux time and extraction solvent wer...

In this study, the performance of an adsorbent coated finned tube exchanger for carbon capture was investigated numerically. The results showed that this structure has a great potential for being applied as a medium for CO2 capture by rapid indirect thermal swing adsorption. By using this structure, the recovery of 96%, and purity of 98% were achieved with a simple cycle consisting of two steps...

Let V be a k-dimensional complex vector space. The Plücker ring of polynomial SL(V ) invariants of a collection of n vectors in V can be alternatively described as the homogeneous coordinate ring of the Grassmannian Gr(k, n). In 2003, using combinatorial tools developed by A. Postnikov, J. Scott showed that the Plücker ring carries a cluster algebra structure. Over the ensuing decade, this has ...
