Microbiologically influenced corrosion (MIC) is a growing problem in the oil and gas industry that results in huge financial losses each year worldwide. Reservoir souring, equipment and pipeline failures due to MIC pitting attacks are of great concerns in field operations. A group of bacteria known as sulfate reducing bacteria (SRB) are often the culprits. Currently, the basic understanding of ...

The computerization of mathematical texts is often a tedious and manual task. The MathLang System was developed to carry out this process in gradual steps. The idea is that the user can annotate an existing mathematical text with different types of information (grammatical/logical/rhetorical/etc.) and MathLang generates different computerised versions of this text which accommodate different le...

Microorganisms that colonize the fuel-in-water emulsion from the Prestige spill have been compared with those from Exxon-Valdez. Both emulsions contained non-fermentative gram-negative rods but unlike Exxon-Valdez’s, the Prestige’s spill contained anaerobic bacteria and no fungi. Our main finding has been the identification of Shewanella putrefaciens, a bacterium promising for bioremediation. T...

Background: Relatively little is known about the genetic basis for the unique physiology of metalreducing genera in the delta subgroup of the proteobacteria. The recent availability of complete finished or draft-quality genome sequences for seven representatives allowed us to investigate the genetic and regulatory factors in a number of key pathways involved in the biosynthesis of building bloc...

The globalization era that began in the decades after World War II, and may now be ending, has a prominent demographic dimension. At its outset, moves toward trade liberalization sought to recreate benign growth experience of late nineteenth early twentieth century, acknowledging harm wrought by protectionist measures interwar years. countries involved this nascent free-trade zone were those co...

Large, contaminated wounds are difficult and expensive to treat. Honey contains many nutrients and minerals and has a bactericidal effect due to hydrogen peroxide liberation and a phytochemical constituent. The use of honey in the management of wounds enhances healing and eliminates invading bacteria without the use of systemic antibiotics. Honey also decreases inflammatory edema. Thus the use ...

We propose that incidental disgust (i.e. disgust triggered by a factor unrelated to the decision at hand) can influence the choice between two commodities, even when decision makers are unaware of the influence. Two experiments tested the hypothesis that decision makers exposed to an incidental disgust prime (as opposed to a neutral prime) would be more likely to dispose of a status-quo object ...
