Gut microbiota facilitates dietary heme-induced epithelial hyperproliferation by opening the mucus barrier in colon [PDF]
, 2015 Colorectal cancer risk is associated with diets high in red meat. Heme, the pigment of red meat, induces cytotoxicity of colonic contents and elicits epithelial damage and compensatory hyperproliferation, leading to hyperplasia.

Sulfide Removal From The Sulfide Spring
Tikrit Journal of Engineering Sciences, 2007 In this study ferrous sulfate had been used as an oxidant for removing the sulfide from water samples taken from sulfide spring in Hamam al-alil south of the Mosul city. The study revealed that ferrous sulfate is efficient in removing sulfide in dose not to exceed to 200mg/l with an efficiency of 77%, also adding of Bentonite clay with ferrous sulfate ...

Modeling sulfide production in full flow concrete sewers based on the HRT variation of sewerage
Water Science and Technology, 2021 The corrosion and odor in concrete sewers are mainly related to the sulfide production, which is, under certain circumstances, directly proportional to the hydraulic retention time (HRT) of the sewer.
