چکیده
Carter, R. C. and Wilde, P., 1972. Cation exchange capacity of suspended material from coastal sea water off central California. Mar. Geol., 13: 107-122. The cation exchange capacity (CEC) of suspended particles (> 0.5 ~) in sea water is measured by a described methylene blue (MB) absorption method which has the following characteristics: sample volume: minimum of 100 ml sea water; time of measurement: about 10 rain; useful range: 0.1-10.0 ~e/~; precision: -+ 0.05 ~te/~ at 0.7 ~e/~2; accuracy: function of organics and clay types. Test of the MB method with sea water samples from the central California off-shore show background values of about 1 ~te/~ with higher values up to 5 ~e/~ in the vicinity of stream discharge.

An Improvement in Cation Exchange Capacity Estimation and Water Saturation Calculation in Shaly Layers for One of Iranian Oil Fields
Water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. In clean formations, by applying the famous Archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can be calculated. Additionally, in shaly sand formations this assumption may not be true as the ion...

Field capacity (FC) and permanent wilting point (PWP) are important factors affecting irrigation scheduling and field management. FC and PWP can be estimated from some of the soil physical and chemical properties. Pressure Plate apparatus is usually used for determination of FC and PWP, but this is a time-consuming and laborious procedure besides, the apparatus may not be available in many labo...
متن کاملIncreased Osteogenic Potential of Pre-Osteoblasts on Three-Dimensional Printed Scaffolds Compared to Porous Scaffolds for Bone Regeneration
Background: One of the main challenges with conventional scaffold fabrication methods is the inability to control scaffold architecture. Recently, scaffolds with controlled shape and architecture have been fabricated using 3D-printing. Herein, we aimed to determine whether the much tighter control of microstructure of 3DP PLGA/β-TCP scaffolds is more effective in promoting osteogenesis than por...

Moist and temperate Caspian forests are associated with a diversity of soil types and topography. Although, natural history and ecological attributes of the Caspian vegetation is well-documented, little is known about mycorrhizae of the Caspian (Hyrcanian) flora. Samples of herbaceous plant species were collected from 4 pre-determined altitudes (-13 upto about 1500m above sea level, appro...
