The phrase "a defining point of" is correct and usable in written English.
It can be used to indicate a significant moment or aspect that characterizes or shapes something.
Example: "The signing of the treaty was a defining point of the nation's history, marking the end of a long conflict."
Alternatives: "a pivotal moment in" or "a crucial aspect of".
This formula is also used to calculate Pob at a defined point of in water wells.
The first represents a group of established photographers, like Lambert, who have a defined point of view and a bit of notoriety as traditional photographers.
The album received a positive review from Jamie Bonk of ZoneMusicReporter.com, who commented: "As far as debut albums are concerned, composer/producer/multi- instrumentalist Chris Field's Sub-Conscious is an outstanding record: great compositions and arrangements, first-rate performances and most importantly a defined point of view".
This induction takes place at a defined optical density (OD) [ 10] or, more often, at a defined point of time [ 10, 14- 16].
In order to simulate such a high-throughput cultivation process, typical steps (clone picking, cryoculture, preculture, main culture and induction at a defined point of time) were conducted with C. glutamicum, another frequently applied and industrially important microorganism.
Another experiment showed that varying growth kinetics, caused by varying initial biomass concentrations (OD600 of 0.0125 to 0.2) led to strongly varying product formation upon induction at a defined point of time.
This situation is observed in all winged insects (Pterygota) [ 60, 61] but, in general, most other panarthropod embryos, such as those of myriapods, chelicerates, and onychophorans, form the endodermal cells at a defined point of the blastoderm [ 10, 62- 67].
The clone E. coli BL21 DE3) pRhotHi-2-EcFbFP [ 24] was used to investigate the influence of different initial optical densities on product formation upon induction at a defined point of time.
Furthermore, the typical process flow from colony picking, preculture and cryopreservation to protein induction at a defined point of time was studied in respect to growth kinetics and product formation.
