Abstract: In this study, two types of commercial nanofiltration (NF) membranes (NF70 and NF270) were chosen to remove four model disinfection by-product (DBP) precursors (resorcinol, phloroglucinol, 3-hydroxybenzoic acid, and tannic ...

Abstract: Current probabilistic methods for maximum and minimum run lengths in a hydrologic time series need further development. Using the first-order Markov chain model and an extreme-value theory for randomly occurring events, ...

Abstract: To investigate the relation between pore structure and compressive strength, ordinary portland cement (OPC) concrete (C), tailings concrete (T), and tailings concrete mixed with steel fiber (TF8) were subjected to dry-wet ...

Abstract: In order to study the relationship between the compressive strength and pore structure of carbonized concrete, normal concrete (NC), basalt-polypropylene hybrid fiber-reinforced concrete (BPC), and steel-polypropylene ...

Abstract: Hybrid-hollow-fiber membrane bioreactors were developed for the enhanced cometabolic biotransformation of phenol and 4-chlorophenol (4-cp) by

Abstract: An immobilized cell hollow fiber membrane bioreactor was operated continuously for the cometabolic transformation of 4-cp in the presence of phenol. In contrast to the batch operation of the bioreactor in which the immobilized ...

Abstract: The cometabolic transformation of high concentrations of 4-chlorophenol (4-cp) in the presence of phenol (growth substrate) was investigated in an immobilized cell hollow fiber membrane bioreactor. The biotransformation ...

Abstract: The evaluation of crossing probability for a given threshold level of a discrete process is an important modeling issue in stochastic hydrology. Rice’s formula is a tool to measure the instantaneous crossing rate for a ...

Abstract: Traditional approaches for repeatedly updating reliability estimates, as needed in reliability-based optimal designs or real-time system control, require the iterative application of a reliability method. This paper explores ...
