The phrase "a defined region of" is correct and usable in written English.
It can be used when describing a specific area or space that has clear boundaries or characteristics.
Example: "The research focused on a defined region of the ocean known for its unique biodiversity."
Alternatives: "a specified area of" or "a designated zone of".
* a defined region of canker radiating upward from the graft union on the north side of the tree.
A subarray is a defined region of the CCD in which data will be taken, rather than the entire chip.
The noise was applied at a proximal site, on a defined region of the tibial nerve path above the ankle.
However, the use of a balancer chromosome (where a phenotypically marked segment of a chromosome is inverted) in a mutagenesis screen enables mutations to be mapped in a defined region of the genome and maintained stably in a heterozygous state.
Cell immobilization is defined as the localization of intact cells into a defined region of space with the preservation of catalytic activity.
In laser-induced injury, thrombosis is induced through heat damage to a defined region of the endothelium, causing morphologic change to the vessel wall.
In June, the ship will be commanded to undock from the ISS and take that refuse - and itself - into a destructive dive through Earth's atmosphere over a defined region of the South Pacific.
The groups of sensor nodes are distributed arbitrarily within a defined region of interest and the BS is situated statically at a remote location, away from the sensor field.
Cell immobilization technology, the localization of intact cells to a defined region of space with the preservation of catalytic activity presents for the biochemical process industry a radical advance, similar to the introduction of heterogeneous catalysis in the petrochemical and heavy chemical industries (Yu et al. 2007; Willaert and Flickinger 2009; Duarte et al. 2013).
Cell immobilization technology, is one useful technique that can be used to efficiently improve ethanol production by maintaining proper mass transfer and biological metabolic activity via the localization of intact cells to a defined region of space and preservation of catalytic activity for further biochemical process.
The results also show that the assembled sequence has very good contiguity partly not only due to successful assembly but also due to a feature inherent in the BAC pooling strategy that every pool is from a defined region of the genome.
