The influence of culture environment on antigen shedding from the surface of colon cancer cells
The roles of some nutrients and environmental factors on CEA synthesis and release has been determined for the LS180 colon cancer cell line. When these cells were grown on various carbohydrate sources, cells grown on mannose ...
EXPERIMENTAL AND ANALYTICAL STOCHASTIC FATIGUE OF WELDED STEEL JOINTS
Thirty-nine welded steel specimens have been tested under variable amplitude loadings to determine the extent to which fatigue life is affected by the amplitude variability of the loading and by the high frequency components ...
Equivalent linearization for random vibrations of a building with yielding girders
The stochastic response of a yielding 2DF system subjected to a stationary Gaussian white noise excitation is investigated. The particular model considered represents a structure with yielding girders, so is more realistic ...
Analysis of stochastic systems with discrete elements
Two new methods for the solution of problems involving material variability are proposed. Medium properties are modeled as second order stochastic processes defined by their mean and convariance functions. Both methods ...
Studies of soil-structure and fluid-structure interaction
This dissertation deals with two distinct topics: (1) The effects of soil-structure interaction, both kinematic and inertial, on the dynamic response of a variety of base-excited foundations and of simple structures supported ...
AN INTEGRATED CONTROL STRATEGY FOR THE ACTIVATED SLUDGE PROCESS
The objective of this study was to develop an integrated control strategy for the activated sludge process. For the purpose of this study, the system included the influent pump station, the biological reactor, the air ...
