  • oxidation
  • 25 ppm of hydrogen sulfide were continuously added to the system in order to provoke an observable catalyst deactivation, and once fully deactivated two different regeneration processes were studied: a self-regeneration and a regeneration by low temperature oxidation. (mdpi.com)
  • Sulfide oxidation proved to be the most resilient process, since it was not affected in any of the experiments, while nitrification and EM removal were severely affected. (springer.com)
  • donor
  • The cardiovascular role of H 2 S was investigated by determining the BP, heart rate (HR), and lumbar sympathetic nerve activity (LSNA) responses elicited by a H 2 S donor sodium hydrogen sulfide (NaHS) or inhibitors of CBS, microinjected into the RVLM and PVN. (frontiersin.org)
  • cells
  • Cells were stimulated with a pro-inflammatory cytokine (interleukin-1β, IL1β, 5 ng/ml) and the ability of the two H2S sources to ameliorate its effects on the cells was tested. (espalibrary.eu)
  • Processes
  • This work studies Ni-based catalyst deactivation and regeneration processes in the presence of H 2 S under a biogas tri-reforming process for hydrogen production, which is an energy vector of great interest. (mdpi.com)
  • Hydrogen sulfide in small quantities is formed everywhere where putrefactive processes take place. (logicieldereferencement.info)
  • geothermal
  • Objectives To study the association between daily mortality and short-term increases in air pollutants, both traffic-related and the geothermal source-specific hydrogen sulfide (H 2 S). (bmj.com)
  • health
  • Practically in every health resort and dispensary, sulfide baths are actively used. (logicieldereferencement.info)
  • Eventually I got better by eliminating chemicals and dental materials (mercury fillings) from my environment which were causing me serious health effects. (hubpages.com)
  • Many people are ignorant of the ill health effects caused by using these types of products. (hubpages.com)
  • Not only are you exposing yourself to products which cause ill health effects, you are failing to do a good job of eliminating germs. (hubpages.com)
  • Indoor material off-gassing and effects on employee health was not fully understood until later and throughout the 20th century as employees moved into new working spaces. (hubpages.com)
  • Hydrogen sulfide emitted from sewers and septic tanks can cause serious health issues. (environmental-expert.com)
  • NaHS
  • Microinjections into the PVN of NaHS, HA, and AOA had no consistent significant effects on BP, HR, or LSNA compared to vehicle. (frontiersin.org)
  • Mobility
  • Whether this is attributable to the mobility of participants or the sheltering effect of buildings is unclear. (massey.ac.nz)
  • ventilation
  • This cause and effect relationship created air ventilation and off-gassing requirement standards prior to building occupancy. (hubpages.com)
