چکیده
ifThe technique of matrix isolation has been used to obtain the infrared spec ra of several high temperature molecules. A double boiler and reaction oven type Knudsen cell technique have been added to the general methods of matrix isolation result g in greater versatility of the method. Differentiation between monomer and polymer spectra appears to be entirely possible. The following molecules have been studied: MgF2» 13> LI2F2, Th02, » 2 and * In most cases tentative frequency assignments have been made and structural properties inferred. Atomic resonance line absorption studies have been carried out on HfB2, TiN and ZrN. Heats of formation have been obtained based on the observed vapor pressures.

Refractory iron deficiency anemia and Helicobacter Pylori Infection in pediatrics: A review
Background Since the discovery of Helicobacter pylori, several clinical reports have demonstrated that H. Pylori infection has emerged as a new cause of refractory iron stores in children. We carried out a systematic literature review to primarily evaluate the existing evidence on the association between childhood H. Pylori infection and iron deficiency anemia (IDA) and secondly, to investigat...
متن کاملEffect of Artemisia absinthium on electrophysiological properties of isolated heart of rats
Introduction: Treatment of supraventricular arrhythmia includes wide range of medical interventions. Herbal remedies are suitable alternatives for synthetic drugs due to their availability, minimal side effects and lower price. Pharmacological studies and traditional medical literature point to the cardiovascular effects of the Artemisia absinthium L. from Compositae family of plants. Meth...

In this paper, gold leaching of a refractory sulfide concentrate by chloride–hypochlorite solution was investigated and effects of stirring speed, temperature and particle size on the leaching rate were reported. Experimental data for leaching rate of gold were analyzed with the shrinking–core model. Results were consistent with chemical reaction control mechanism in the first 1 h of leachin...
متن کاملFAILURE MECHANISMS OF REFRACTORY LININGS FOR NONFERROUS FLASH SMELTING FURNACES
Although the flash smelting technologies use different furnace designs, the refractory linings are exposed to very similar aggressive environments and, as a result, the corrosion analysis results on one type of furnace could be generally applied to other furnaces of similar high temperature processes. Particularities regarding the different chemistries of the pyrometallurgical process and opera...
متن کاملInvestigations of Calcium Aluminate Slag Penetration to MgO Monolithic Refractories in Steelmaking Process
In this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. A synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°C and 1600°C. It has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°C. In this case, capillaries are the ...
