The phrase "availability of controlled" is not complete and lacks context, making it difficult to assess its correctness in written English.
It could be used in contexts discussing the accessibility or presence of something that is regulated or managed, but it needs additional information to clarify its meaning.
Example: "The availability of controlled substances is strictly monitored by regulatory agencies."
Alternatives: "accessibility of regulated" or "presence of managed".
The availability of the controlled mechanism is an important factor to define tolerance of different varieties against drought.
To analyze the availability of randomized controlled trials (RCTs) of new drugs in trial registries and to develop and test different search strategies in ClinicalTrials.gov (CT.gov), the EU Clinical Trials Register (EU-CTR), and the International Clinical Trials Registry Platform ICTRPP).
Furthermore, the availability of numerous controlled human studies makes reliance on animal data unnecessary for evaluating this endpoint.
The methodology for pricing ethanol will ultimately depend upon the size of the total fuel ethanol market, the political priority given to the support of alternative fuels and the availability of politically controlled incentives such as carbon credits.
For example, the HTA approach for medical devices is different from pharmaceuticals due to the limited availability of randomised controlled trials (RCTs), and other methodological problems such as multiple indications, frequent product modifications, learning curves, and high fixed cost [ 7].
These considerations being the need for other approaches due to the limited availability of randomised controlled trials, measurement of a range of outcomes beyond Quality Adjusted Life Years (QALYs), consideration of inter-sectoral costs and consequences which may include wider benefits and spill over effects, and a focus on equity.
Advances in experimental techniques, such as the availability of well-controlled straining stages for optical and electron microscopes, the focused ion beam, electron backscattered diffraction, and nanoindentation, enable probing at these length scales in real time and through interrupted tests.
These applications depend on the availability of homogeneous nanoparticles of controlled size and shape, which remain stable in their complex target environments [13, 14].
The availability of such well-controlled NPG structure will provide an interesting possibility for a more in-depth fundamental investigation of transport behavior in the highly interconnected graphene network, and will enable exciting opportunities in sensitive electronics and sensor devices.
