Ash Wednesday Mass During service, priests usually share a speech that focuses on reflection and penance and encourages people to confess and pray for their sins. When anointing churchgoers with the ash cross on their forehead, priests will pronounce a variation of the words “From dust you ...
In modern times, some clergy have seen Ash Wednesday as a chance to do some guerilla evangelism, going out into their cities and offering ashes to passers-by on sidewalks, even to drivers stopped at traffic lights. The main thrust overall is that when the faithful set aside certain bodily ...
A thermogravimetric curve describes mass loss as a function of temperature, which provides information regarding thermal stability and composition of the initial sample, whereas a DTG curve is the measurement of the weight loss ratio at heating interpretation over time (T). Thermogram of samples 0%...
The mass variation and the compressive strength have also been studied. The impedance spectroscopy has been the most sensitive technique for following the sulphate attack process. Considering the results obtained, micropiles grouts with slag and fly ash, exposed to an aggressive medium with high ...

From Figure 7b, the drug loading of MS-24h was 6 times higher than that of TMMS-g-MS. Ibuprofen has one aromatic ring and a relatively long and flexible hydrophobic moiety (butyl group). As a result, the ibuprofen molecules could favourably pack on the surface, leading to a high ...

Two dosage parameters that have been proposed in this study are the silica modulus (SM), i.e., the mass ratio of SiO2/Na2O, and the alkali dosage (M+), i.e., the mass ratio of Na2O/binder expressed in percentage. Many studies in the geopolymer literature showed the importance of ...
