How to Calculate CFU From Dilution | Sciencing, · Colony forming units (CFU) refer to the number of individual colonies of any microorganism that grows on a plate of media. This number is useful when trying to find how many viable microorganisms are contained within a sample. Plating dilutions of such a sample isFlow, · By adjusting the region settings, an optimum FOM can be found, which is calculated as (10.1) FOM = E 2 / B where E is the percent counting efficiency and B is the background count rate. An optimum FOM can provide higher sensitivity for radionuclide detection by reducing the MDA as described further on in this chapter.Clarifier, · Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge ...Charging Batteries with Solar Power or a Wind Turbine, · BU-413: Charging with Solar, Turbine Learn about charging your batteries from renewable resources and what it costs. Folks concerned about the environment gravitate towards using renewable energy. The sun provides peak power of about 1,000 watts per square ...Standard operating procedure, · SOPs aim to achieve efficiency, quality output and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations. The military (e.g. in the U.S. and UK) sometimes uses the term standing (rather than standard ) operating procedure because a military SOP refers to a unit's unique procedures, which are not necessarily standard to another unit..
Sensor, · Sensor-based sorting, is an umbrella term for all applications where particles are singularly detected by a sensor technique and rejected by an amplified mechanical, hydraulic or pneumatic process. The technique is generally applied in the three industries mining, recycling and food processing and used in the particle size range between 0.5 and 300 mm (0.020 and 11.811 in).Earthing in electrical network, · Earthing in electrical network The main reason for doing earthing in electrical network is for the safety. When all metallic parts in electrical equipment are grounded then if the insulation inside the equipment fails there are no dangerous voltages present in the equipment case.4 Types of DC Motors and Their Characteristics, · The field of DC motors can be a permanent magnet, or electromagnets connected in series, shunt, or compound. Coupled with a DC drive, they provide DC Motor Characteristics As you already know, there are two electrical elements of a DC motor, the field windings and the armature.The armature windings are made up of current carrying conductors that terminate at a commutator.
