A method for controlling the gastric pH of rabbits to low acidity (pH > 4) by using different antacids was investigated, and the physiological state of rabbits during gastric-acidity control and repeated bioavailability tests was also examined in terms of hemocytological and clinicobiochemical parameters. Neither dried aluminum hydroxide gel (DAH) nor synthetic aluminum silicate (SAS) could ele...

The present study firstly proposed a method of integrated utilization of sewage sludge (SS) and coal gangue (CG), two waste products, for cement clinker products with the aim of heat recovery and environment protection. The results demonstrated that the incremental amounts of SS and CG addition was favorable for the formation of tricalcium silicate (C₃S) during the calcinations, but excess amou...

Introduction: The presence and amount of Si in Earth's core has important implications for models of the processes and chemistry of core segregation. A metal core containing 5 to 7 wt. % Si can be produced when assuming continuous accretion and equili-bration along the silicate liquidus terminating at ~35 GPa and ~3,000 K, and with a concomitant increase in fO 2 from 4 to 2 log units below IW [...

Introduction: The compositional characteristics of the Earth's core-mantle system are best described by a model that recognizes that the present upper mantle is not in equilibrium with the core and that metal-silicate differentiation was in response to secular changes in equilibrium conditions [1-5 and references therein]. Au) that are ~100-fold depleted relative to chondritic meteorites [6-7]....

Arsenic (As) contaminated aquifers contain iron minerals and clays that strongly bind As at their surfaces. It was suggested that As mobilization is driven by natural organic matter (including fulvic acids (FA) and humic acids (HA)) present in the aquifers either via providing reducing equivalents for reductive dissolution of Fe(III) (hydr)oxides or via competitive desorption of As from the min...

background: biting habit of mosquitoes plays an important role in the epidemiology of mosquito-borne diseases. mosquitoes use a set of elaborate sensory modalities to find their preferred hosts by exploiting cues emanating from a nearby host. it has been suggested that the chemical profile of skin can provide further support for anthropophilic mosquito species to find their suitable hosts. this...

The 8–14 µm emission spectra of 12 T Tauri stars in the Taurus/Auriga dark clouds and in the TW Hydrae association obtained with the Infrared Spectro-graph (IRS 1) on board Spitzer are analyzed. Assuming the 10 µm features originate from silicate grains in the optically thin surface layers of T Tauri disks, the 8–14 µm dust emissivity for each object is derived from its Spitzer spectrum. The em...
