cellulose is a raw material which is extensively used in the manufacture of paints, papers, textiles, agricultural products and cosmetics. the waste of sugar beet pulp after titration is a source of cellulose. the current study was carried out to study the possibility of cellulose production from sugar beet pulp waste at titration stage as a 3×3×2 factorial study on the basis of a randomized co...

We experimentally and theoretically demonstrate the purity (polarization) control of qubits entangled with multiple spins, using induced dephasing in nuclear magnetic resonance setups to simulate repeated quantum measurements. We show that one may steer the qubit ensemble towards a quasiequilibrium state of a certain purity by choosing suitable time intervals between dephasing operations. These...

Moral violations are typically defined as actions that harm others. However, suicide is considered immoral even though the perpetrator is also the victim. To determine whether concerns about purity rather than harm predict moral condemnation of suicide, we presented American adults with obituaries describing suicide or homicide victims. While harm was the only variable predicting moral judgment...

UNLABELLED The purpose of this investigation was to develop and evaluate a new and rapid miniaturized chromatography system that would accurately assess the radiochemical purity of 99mTc-tetrofosmin without the problems of solvent ratios and time requirements associated with the manufacturer's recommended procedure. METHODS The migration of the radiochemical components of 99mTc-tetrofosmin wa...

The design, optimization and better control of refinery processes become possible via dynamic simulation. In this article, a methanol distillation unit with three columns has been simulated to separate methanol from its impurities and water in steady and dynamic states, using commercial softwares. Moreover, it investigates, employing simulink/matlab software, the effect of variable changes on p...

Purity in module categories and its different generalizations have been present in the literature since the 1960s. Apart from its special role in module theory, the importance of purity increased during the last two decades through the developments of model theory and the study of locally finitely presented categories (e.g., [2, 6]). In the module theory context, that will be our framework, a p...

In this study, total crocin was extracted from saffron stigmas using crystallization method. Ethanol 80% was selected as the best extraction solvent. Crystallization process was carried out in one and two steps at different temperatures. Ethanol 80% was used as crystallization medium. Crocin crystals obtained from the first crystallization had low purity and thus were subjected to the second cr...
