"The changes in the political situation make it less viable, less feasible to maintain engineers here, and that is not even counterbalanced by the fact that engineers get cheaper by the day because of the [falling value of the] rouble," Nossik said.
If cost-efficient operation is to be maintained, engineers must continue to seek new and effective maintenance and operating systems for both infrastructure and rolling stock.
The aim of the present study was to estimate the potential of RINmS cells to maintain their engineered characteristics during in vivo hyperglycemic conditions.
Stably transformed T. gondii expressing the dsRNA, which was capable of growing in the presence of the prodrug 5-fluoro-2′-deoxyuridine (FDUR), appeared to maintain the engineered plasmid as an extra-chromosomal DNA.
Throughout all experiments, cultures and biofilms were grown at 30°C in M9-AADO (Amino Acid Drop Out) medium without lysine, containing 50 µg ml−1 kanamycin and 20 µg ml−1 tetracycline to maintain the engineered and the marker plasmids, respectively [34].
All macaques maintained stable circulating CD4+ T cells, developed low viral loads, maintained the engineered mutations, yielded no histological lesions, and developed immunoprecipitating antibodies early post-inoculation.
With respect to the latter, most US codes of ethics maintain that engineers 'should hold paramount the safety, health and welfare of the public'.
Organ formation and regeneration require epithelial progenitor expansion to engineer, maintain, and repair the branched tissue architecture.
Plasmids are often not maintained in genetically engineered bacteria in the absence of selective pressure and are lost during attempts at practical application.
Reverse engineering activities support the obtainment of abstractions and views from a target system that should help the engineers to maintain, evolve and eventually re-engineer it.
