15 صفحه اولsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Phytochrome-mediated growth inhibition of seminal roots in rice seedlings.
In rice (Oryza sativa) seedlings, continuous white-light irradiation inhibited the growth of seminal roots but promoted the growth of crown roots. In this study, we examined the mechanisms of photoinhibition of seminal root growth. Photoinhibition occurred in the absence of nitrogen but increased with increasing nitrogen concentrations. In the presence of nitrogen, photoinhibition was correlate...
متن کاملAcidification of Deionized Water by Roots of Intact Rice Seedlings
This investigation was designed to examine whether or not deionized water could be acidified by roots of intact rice seedlings. Roots of intact rice seedlings caused significant acidification of the deionized water in which they were immersed and this acidification could be repeated after replacement of acidified water with fresh deionized water. The addition of K, Na, and Mg* to the deionized ...
متن کاملDiterpene phytoalexins are biosynthesized in and exuded from the roots of rice seedlings.
Rice (Oryza sativa L.) produces a variety of diterpene phytoalexins, such as momilactones, phytocassanes, and oryzalexins. Momilactone B was previously identified as an allelopathic substance exuded from the roots of rice. We identified in this present study momilactone A and phytocassanes A-E in extracts of, and exudates from, the roots of rice seedlings. The concentration of each compound was...
