Silicon (Si) enhances the stress resistance of rice plants. Silicon cycling in paddy fields is, however, still poorly studied. We examined relationships between Si forms in topsoil and plant Si uptake for four Vietnamese and three Philippine regions (ten fields per region). Mean rice straw Si concentrations within regions ranged from 3.0 to 8.4 %.

Hydrogen sulfide (H 2 S) is a very toxic and pungent gas that causes problems in both the upstream and downstream oil and gas industry. The process of removing H 2 S is known as gas sweetening, by either iron sponge H 2 S scrubbers (forming iron sulfide) or chemical scavengers.Typical H 2 S scavengers used in the oilfield are amine based chemicals .They can be roughly egorized into
