simulation 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. ...
Photosynthate transport using tritiated water.
The exchange of HTO with aerial portions of the soybean was studied under a variety of conditions. When fed to a lone leaf or leaflet in a saturated air atmosphere (all other leaves and the growing point having been excised), the HTO profile virtually ceases at a distance of 2 cm from the feeding chamber in the photosynthetic plant, but is greater and more extensive in the unilluminated plant. ...
متن کاملBody water estimation in the newborn using tritiated water.
Of all the substances used for the estimation in vivo of total body water content, the most attractive are the isotopes of hydrogen, since they enter into all the metabolic processes involving water and have no selective secretion or storage. Deuterium was the first substance used for body water estimation in vivo (Hevesy and Hofer, 1934) and is preferable to tritium because it is not radioacti...
متن کاملGamma Radiation Measurement due to Natural Radioactivity in Hot Water Spring of Behbahan
Introduction: Many people use hot water springs to treat some diseases, such as rheumatism, arthritis, and skin diseases, but they are unaware of the presence of natural radioactive substances that may be found in hot water springs. An effective way to understand the radiation risk of these elements are measuring the dose rate of radiation. In this study, for the first time, ga...
متن کاملTranslocation of sugar and tritiated water in squash plants.
When (14)C-sugar and THO were simultaneously introduced through a cut side vein or flap of a squash leaf (Cucurbita melopepo, Bailey cv. torticollis) concurrent translocation of (14)C-sugars, T-photosynthates and THO with parallel, almost flat, gradients was observed in the petiole for periods of 1 to 3 hr. Parallel translocation gradients were not observed when (14)C was introduced as (14)CO(2...
