APPLICATION OF AGRO BASED RESUIDALS FOR THE PRODUCTION OF SURACTANT ON IOR USING MICROBES
Abstract: Utilization of surfactants for IOR is an accepted technique with high potential. However, technology application is frequently limited by cost. Biosurfactants (surface-active molecules produced by microorganisms) are commonly used in specialty markets such as food and textiles and have potential for IOR application. Currently, biosurfactants are not widely utilized in the petroleum industry due to high production costs associated with use of expensive substrates and inefficient product recovery methods. The …

Assessment of Compressive Strength of OPC and PPC-Based Concretes Combined by Ultrasonic Pulse Velocity and Rebound Hammer
Abstract: In this study, non-destructive tests were performed on ordinary Portland cement (OPC) and Portland pozzolana cement (PPC) based concrete specimens, namely the ultrasonic pulse velocity (UPV) and rebound hammer (RN). A relationship is thus established between the NDT values and the compressive strength. A statistical regression analysis was performed between the compressive strength with UPV and RN values to obtain a best-fit relationship and correlation coefficients. To take into account …

FPGA-based Multichannel Digital Duty-Cycle Modulation and Application to Simultaneous Generation of Analog Signals
Abstract: The DCM (duty-cycle modulation) is used in industrial electronics as a special technique for producing switching time-varying periodic waves, with variable pulse width and modulation period. As an implication, unlike the fixed period of a PWM wave, the cyclic ratio of a DCM signal changes as a function of the modulating input according to a known function. However, most existing research works related to DCM-based instrumentation systems, are limited to …
