Abstract The stability of amino acids in solutions containing electrolytes and the effect ambient pH on their biological activity is an important research area. In this work, volumetric transport properties ionic liquid (IL) aqueous solution with special performance 1-(2-carboxyethyl)-3-methylimidazolium chloride ([HOOCEMIM][Cl]) were studied. selected IL acts as electrolyte allows study system...

VOLUME LI NUMBER 3 © 2017 JCO, Inc. Orthodontists can never have enough techniques in their armamentaria for uprighting mesioangular lower second molars. In this Pearl, as an alternative to a Halterman appliance, the authors use a beta titanium U-loop extended distally from the first-molar band to upright an impacted second molar. Note the crimpable stops on the U-loop to prevent the wire from ...

Analytical expressions are derived for the melting line and liquid equation of state of normal deuterium near the triple point. Melting pressures were measured between the triple point and 20.4 K. These results combined with existing pressure measurements along the saturated liquid-vapor curve fix an accurate value. Ttp =j118. 723 K, for the triple-point temperature. Data for the isothermal com...

In this study, Chemical Oxygen Demand (COD) from a pharmaceutical wastewater (PhW) was reduced by several techniques such as electro-Fenton (EF), photo electro-Fenton (PEF) and activated sludge (AS) processes and the obtained data were compared with each other. The effects of several parameters such as pH, current density, H2O2/Fe2+ molar ratio, volume ratio of ...

Environmental and other applications of cyclodextrins (CD) often require usage of high concentration aqueous solutions of derivatized CDs. In an effort to reduce the costs, these studies also typically use technical grades where the purity of the CD solution and the degree of substitution has not been reported. Further, this grade of CD often included high levels of salt and it is commonly appl...

A shortened dental arch without posterior occlusal support has been thought to maintain sufficient oral function. The mechanism of occlusal adaptation with a shortened dental arch is unclear. For a better understanding of the effects of molar teeth on brain function, the authors combined experimentally-shortened dental arches and a neuro-imaging technique. Regional cerebral blood volume was mea...

Since abnormal tooth morphology can predispose to caries and periodontal disease, careful management of fused teeth is essential. In this paper we report a rare case of a fused molar and supernumerary tooth and describe its management. Caries was removed from the tooth complex under local anesthesia. The pulp chamber of the supernumerary tooth was exposed without involvement of second molar pul...
