When gasoline prices soared last spring, there was a push for more stringent light truck standards by Democratic and Republican senators from Western states where people drive long distances.
The principles forming the basis of the new strategy Europe 2020, have become even more stringent in light of the state of emergency, which led, at European and national level, the need to develop the exceptional measures in the programming and reprogramming financial resources, in particular related to structural funds.
The light-regulated vvd promoter is highly tunable but requires stringent control of lighting conditions during tissue collection (Hurley et al. 2012).
For example, the limitation is more stringent at higher light levels, colder temperatures and high CO2 levels.
Interestingly, none of the other clock components and modifiers of the components, including FRH (FRQ-Interacting RNA Helicase), a binding partner of FRQ necessary for negative feedback (Guo et al. 2010), and several kinases (CK1, CK2, PKA, and CAMK-1) and phosphatases (PP1, PP2A, and PP4) that modify the activities of the clock components, met our stringent criteria for light regulation.
Conventional flexible fiber-type dye-sensitized solar cells (F-DSSCs) based on polymer/ITO (indium tin oxides) usually suffer from several problems such as cost inefficiency, stringent temperature restriction, and light-reception-angle limitation.
In light of increasingly stringent diesel emissions limits, research efforts have been invested into HCCI combustion as an alternative to conventional diesel combustion.
Like most federal government mandated fixes, raising the CAFE standards seems short sighted in light of increasingly stringent safety requirements.
Plot showing number of pairs of sites in significant LD in both populations in the stringent and relaxed data sets (light blue).
Diurnal teleost reef fish, released from the stringent functional requirements of dim-light vision have much higher morphological and optical diversity than nocturnal species, with large ranges of optical ratio, depth of focus, and lens accommodation.
