10213: Demystifying MIC Mechanisms
نویسنده
چکیده
Microbiologically Influenced Corrosion (MIC) is becoming increasingly important, especially to the oil and gas industry as more and more reservoirs are soured due to increased practice of water flooding and pipelines are aging (some even beyond their anticipated life expectancies). Despite the fact that MIC research has been going on for several decades, there is much confusion in the MIC literature regarding the fundamental mechanisms in MIC. This has greatly hindered the development of reliable prediction and new mitigation methods. A new MIC theory entitled Biocatalytic Cathodic Sulfate Reduction (BCSR) theory was presented in NACE/2009. It sheds some lights on MIC mechanisms. This work demonstrates how the theory together with bioenergetics, electrochemical kinetics, and mass transfer can be used to explain various mysteries in MIC. Some experimental data and model simulation results for MIC due to sulfate reducing bacteria (SRB) and acid producing bacteria (APB) are used in the explanations.

Evolution and Mode of Action of Pulsed Radiofrequency
Implication for health policy/practice/research/medical education: PRF was initially regarded as a method of blocking nociceptive stimuli that is less destructive than a thermolesion. Since the introduction of the intra-articular application this concept has changed. PRF is now thought to have an anti-inflammatory effect on the immune system, acting on the nociceptive process itself instead of...

Inter-tumor heterogeneity might explain divergent clinical evolution of cancers bearing similar pathological features. In the last decade, genomic has highly improved tumor subtypes classification through the identification of oncogenic or tumor suppressor drivers. In addition, epigenetics and long non-coding RNAs (lncRNAs) are emerging as new fields for investigation, which might also account ...

Electron Paramagnetic Resonance (EPR) spectroscopy, also known as Electron Spin Resonance(ESR) especially among physicists, is a strong and versatile spectroscopic method forinvestigation of paramagnetic systems, i.e. systems like free radicals and most transition metalions, which have unpaired electrons. The sensitivity and selectivity of EPR are notable andintriguing as compared to other spec...
متن کاملDemystifying the digital divide.
policy leaders and social scientists have grown increasingly concerned about a societal split between those with and those without access to computers and the Internet. The U.S. National Telecommunications and Information Administration popularized a term for this situation in the mid-1990s: the “digital divide.” The phrase soon became used in an international context as well, to describe the s...
