WebJun 17, 2024 · The purpose of this study was to determine what role aquaporins play in water permeability in the hypoxia-tolerant euryhaline common killifish (Fundulus heteroclitus), in two important osmoregulatory organs—the gills and intestine. Using immunofluorescence, we localized aquaporin-3 (AQP3) protein to the basolateral and … In application, permeability estimates are extracted from a bin addressed by the log values. An interpolation scheme is used to extract an estimate from an empty bin. Like the regression method, the database approach can be used only when adequate core data are available to build the model, and results generally … See more A widely used statistical approach is multiple linear regression.Linear regression techniques are popular for establishing predictors of geological variables because the methods are effective at predicting … See more A database approach equivalent to an n -dimensional lookup table can also be used for predicting permeability within a field or common geology. In … See more Artificial neural networks are a third method of establishing a predictor specific to an area of interest. A back-propagation neural network is … See more Fuzzy clustering techniques provide a means of determining the number of clusters (bins in the preceding paragraph) and their domains. … See more

WebDec 27, 2024 · The model seems to capture the most important permeability features. The prediction of log P app (Caco-2/MDCK, pH 7.4) with Eq (2) is satisfying (R 2 = 0.77, RMSE = 0.48), especially if one considers the high experimental uncertainty that becomes visible in the experimental scatter for single chemicals. Note that also some of the partitioning ... WebFeb 1, 2024 · The accurate measurement or estimation of reservoir permeability and porosity is of great significance. Core measurements and well logs are the main ways to determine the reservoir permeability and porosity in the oil and gas industry. WebJul 16, 2015 · Semmelbeck et al. explained how mud filtrate invasion in low permeability formations affect the deep induction (R ild) and the medium induction log (R ilm) differently as a function of time. Thus, if one has multiple logging runs, one can evaluate how the ratio of R ild /R ilm varies and can correlate that ratio with formation permeability. meek mill cold hearted 2 mp3 download
