Local Maximum and Minimum Values
0 Views •
2026
In multivariable calculus, a function of two variables can exhibit local maximum or minimum values at certain points on its surface. A local maximum occurs when the function's value at a point is greater than at all nearby points, while a local minimum occurs when the function’s value is less than at all nearby locations. These points are referred to as local extrema and are of central importance in optimization problems.Local extrema are found at critical points, where the surface becomes...

2017
We present an apparatus based on hot-wire ignition in a pressurized enclosure and an associated methodology to measure the minimum pressure required to induce sustained combustion in water-based emulsion explosives. This method improves product characterization to allow one to use them more safely during pumping and mixing operations.

A Microtiter Plate Method to Assess the Minimum Inhibitory Concentration of an Antibiotic

2025
This video demonstrates a microtiter plate-based method for determining the Minimum Inhibitory Concentration (MIC) of test antibiotics against bacteria. Upon adding a suspension of the bacterial pathogen Pseudomonas aeruginosa to a microtiter plate containing serial dilutions of a test antibiotic, and an inhibitor of the production of pyomelanin by the bacteria, the optical density of the wells is measured to compute the minimum inhibitory concentration of the antibiotic, and the impact of the...

This manuscript describes a protocol for the minimum volume vitrification of immature cat oocytes with laboratory-made media on commercial supports. It covers every step from oocyte isolation from ex vivo gonads to vitrification and warming.
FAQs
The omission creates a defined nutrient background in which the separately supplied hydrocarbon becomes the relevant carbon and energy source. Because nitrogen, phosphate, magnesium, calcium, and iron remain available, microorganisms receive essential inorganic support without an alternative organic carbon supply. This design strengthens interpretation of growth during hydrocarbon-utilization studies.
The mineral salts provide the inorganic nutrients needed to sustain microbial activity while leaving the carbon source experimentally controlled. Their presence allows researchers to evaluate whether an isolate can grow with a hydrocarbon substrate rather than failing because essential nutrients are absent. This separation helps connect observed growth with substrate utilization.
Its selective composition limits readily available organic carbon, so growth is interpreted in relation to the hydrocarbon added separately. The medium therefore reduces the possibility that an isolate is growing on an unintended organic nutrient. This distinction is important when screening environmental microorganisms for petroleum degradation or related metabolic activity.
A consistent mineral-salts background allows researchers to compare microbial growth associated with different separately added hydrocarbons under controlled conditions. Since the basic inorganic nutrient supply remains defined, differences in observed growth can be examined in relation to the hydrocarbon substrate rather than changing nutrient composition. This makes the medium useful for comparative biodegradation studies.
Researchers provide the defined mineral-salts medium, add the hydrocarbon being evaluated as the separate organic substrate, and introduce the environmental isolate under controlled study conditions. They then assess whether growth occurs. This workflow screens the isolate for hydrocarbon utilization while maintaining a composition that limits support from unrelated organic nutrients.
Researchers use it when they need to screen environmental isolates for petroleum degradation, compare hydrocarbon biodegradation, or examine microbial activity associated with contaminated environments. Its defined composition is particularly useful when the study must connect microbial growth with a selected hydrocarbon substrate rather than with complex, readily available organic nutrients.
Growth provides evidence that the tested microorganism can use the supplied hydrocarbon as a carbon and energy source under the study conditions. This result can support evaluation of petroleum-degrading potential and help compare microbial activity among environmental isolates. The medium therefore links a visible biological outcome with a specific metabolic capability.
Contaminated-environment studies often investigate whether resident microorganisms can contribute to petroleum degradation. By supplying essential inorganic nutrients while testing a separately added hydrocarbon, the medium offers a controlled way to examine that capacity. Results can help researchers identify isolates whose growth is associated with hydrocarbon utilization and compare their biodegradation potential.
