STATEMENT OF THE PROBLEM Premedication is expedient in reducing the psychological trauma from recalling the unpleasant pre-anesthetic phases, hence, inducing a trouble-free anesthesia. PURPOSE This study aimed to determine the effectiveness of oral midazolam in co-operation of the subjects before general anesthesia and in recalling the pre-anesthetic phases, performed on children candidate fo...

CO2 is the primary anthropogenic greenhouse gas, accounting for 77% of the human contribution to the greenhouse effect in 2004. In the recent years, global concentration of CO2 in the atmosphere is increasing rapidly. CO2 emissions have an impact on global climate change. Anthropogenic CO2 is emitted primarily from fossil fuel combustion. Carbon capture and storage (CCS) is one option for reduc...

The aim of this paper is to introduce and study two new classes of spaces, called g∗-pre regular and g∗-pre normal spaces. Some basic properties of these separation axioms are studied by utilizing g∗-preclosed and g∗-preopen sets. A subset A of a space X is called g∗-preclosed (briefly g∗p-closed) set if pcl(A) ⊆ U whenever A ⊆ U and U is g-open in X. Mathematics Subject Classification: 54D10, ...

In this work, separation performance of supported carbon membranes produced from Novolac Phenolic resin as the main precursor and carbon nanotubes as nanofiller were investigated for separation of CO2 from N2 and CH4. Supports were produced by carbonization of Novolac Phenolic resin-activated carbon mixture, and selective layer was coated by dip coating of prepa...

A rapid, sensitive, and reproducible pre-column derivatisation procedure has been established for the simultaneous determination of 20 amino acids by high-performance liquid chromatography using fluorescence detection. The amino acids were derivatized using o-phthalaldehyde and 9-fluorenylmethyl-chloroformate reagents. The optimal conditions for simultaneous separation and detection of both pri...

A neutron activation analysis method with pre-irradiation separation and post-irradiation purification is presented for the determination of 129I content and 129I/127I ratio in some environmental samples, such as seawater, seaweed, grass and soil. An evaporation concentration followed by solvent extraction was used for the separation of iodine from seawater, and alkaline ashing or alkaline fusi...
