Abstract: The present invention is a method for the early detection or prediction of souring of aqueous systems by detecting a population of lipid and organic acids and the treatment of such systems.

Abstract: Methods are provided for detection of souring or the likelihood of souring in an oil and gas process fluid which involves analysis of an aqueous sample obtained from an oil and gas process fluid for the presence of bacteria of at least two different bacterial genera, wherein the genera are selected from Pelobacter, Flexistipes, Marinobacterium, Geoalkalibacter, and Halanaerobium. The presence of bacteria from two or more said genera indicates the likelihood of increased sulfide production in the fluid. Other related methods and reagent compositions for performing the methods are provided.

Abstract: A temperature controlled tissue dissection and observation stage comprises a central working area and a first temperature controlled station positioned within the central working area. The first temperature controlled station comprises a first temperature controlling element configured to adjust the temperature of the first temperature controlled station. The stage further comprises a user input device in communication with the first temperature controlling element. In one embodiment, the stage comprises four temperature controlled stations. Three of these stations are designed to house petri dishes filled with solutions required for tissue restoration and reconstruction surgeries, and the fourth station is configured to function as a flat cutting surface for the user. In one embodiment, thermostatic control over the system is achieved through the integration of thermoelectric coolers, a microcontroller, and feedback temperature sensors.
