In order to improve the whiteness of fly ash, the particles were coated by in-situ precipitation of calcium carbonate. After different mass ratios of calcium oxide to fly ash were mixed into water, a certain amount of carbon dioxide was bubbled into the mixture to form a precipitated calcium carbonate deposit on the surface of fly ash. With the help of scanning electron microscopy (SEM), the pr...

A father recounts a transformative journey of love, loss, and learning as his son developed and eventually died of a fungal infection that occurred during a period of immunocompromise after a bone marrow transplantation to treat hypodiploid leukemia. He then thanks the many physicians, researchers, family members, and friends who came together to memorialize his son and create knowledge, hope, ...

Eventually, the two take up residence in New Hampshire, where Birdie passes as "Jesse"and for white. This a...

This paper aims at obtaining universal laws and absolute lower bounds of feedback systems using information theory. The feedback system setup is that with causal plants and causal controllers. Three laws (entropy rate never decreases, generalized Bode integral, and absolute lower bound in variance minimization) are obtained, which are in entropy domain, frequency domain, and time domain, respec...

The power, privilege, and oppression paradigm that most schools of social work currently espouse to are often taught through an experiential approach whiteness, privileging the majority white students with opportunity explore their identity at expense learning Black/Brown, Indigenous, People Color (BIPOC) in classroom. Many BIPOC experience these courses as a hostile environment, finding themse...

enzymatic browning and formation of brown pigments are some of the most important problems in preparation of mushroom purees. in this study, the effect of some anti browning agents including sodium metabisulphite, ascorbic acid, and citric acid on the whiteness and foaming properties of mushroom purees was investigated. the results showed that soaking with acids and sodium metabisulphite signif...

Appearance of rice grain is an important property, affecting its acceptance by consumers. Moreover, appearance is a complex characteristic involving many components, including glossiness and whiteness. The genetic bases for the glossiness of cooked rice and the whiteness of polished rice (WPR) were determined using 133 recombinant inbred lines (RILs) derived from a cross between two closely rel...

The aim of this study was to evaluate the surface roughness, microhardness and morphology of human enamel exposed to six bleaching agents (at baseline and post-treatment). Human dental enamel samples were obtained from human third molars and randomly divided into seven groups (n = 11): control, Whiteness Perfect 10% carbamide peroxide (10% CP), Colgate Platinum 10% CP, Day White 2Z 7.5% hydroge...
