Color is an important qualitative factor in tomato products such as tomato paste which is affected by heat processing. The main goal of this study was to evaluate the degradation kinetics of tomato paste color during heat processing by Arrhenius equation and modeling of these changes by response surface methodology (RSM). Considering this purpose, tomato paste was processed at three temperature...

In 2010 Jewitt and Li published a paper examining the behavior of comet-asteroid transition object 3200 Phaethon, arguing it was asteroid-like in its throughout most orbit, but that near perihelion, at distance only 0.165 AU from sun, dayside temperatures would be hot enough to vaporize rock (>1000 K, Hanus et al. 2016). Thus act like "rock comet" as gases produced evaporating were released bod...

The kidney normally functions to maintain hemodynamic homeostasis and is a major site of damage caused by drug toxicity. Drug-induced nephrotoxicity is estimated to contribute to 19- 25% of all clinical cases of acute kidney injury (AKI) in critically ill patients. AKI detection has historically relied on metrics such as serum creatinine (sCr) or blood urea nitrogen (BUN) which are demonstrably...

Chemical weathering indices are commonly used for characterizing weathering profiles by incorporating bulk major element oxide chemishy inlo a single metric for each sample. Generally, on homogeneous parent rocks, weathering indices change systematically with depth. However, the weathering of heterogeneous metamorphic rocks confounds the relationship between weathering index and depth. In this ...

River regulation is challenging when there diverse upstream and downstream interest, leading to regional international conflict. However, quantifying the upstream-downstream flow regime changes their causes are given less consideration in river basin. In this study, we presented three new ratios for downstream-upstream low contribution (DUL), high ratio (DUH), meteorological-hydrological drough...

This study investigated the physicochemical properties and sensory attributes of Yanggaeng, a traditional dessert in Far East Asia, treated with functional additive Corni fructus powder (CF) various concentrations (0% [control; CON], 2%, 4%, 6%). The proximate compositions, properties, antioxidant capacities, texture consumers’ preferences CF-treated Yanggaeng were assessed. had decreased L* (l...
