However much it is denied, an ancient system of bondage, with black slaves passed on from generation to generation, still plainly exists.
Although the firm's managers insist that.NET is based on open XML standards, it is nonetheless tied to Windows and leaves Microsoft essentially in control.So far, however, much of.NET exists only on colourful slide presentations to impress Wall Street and, more importantly, to lure software developers back from the Java world and keep others from jumping in.
However, much debate exists about the efficacy of these international assessment tools in measuring building performance outside their country of origin, due to global variations in climate, geography, economics and culture.
However, much room exists for further improvement.
However, much ambiguity exists whether MDR gram-negative isolates possess different virulence characteristics from susceptible gram-negative isolates.
However, much uncertainty exists about the mechanistic links between CFTR mutation and the pleiotropic nature of the resultant multi-organ CF disease [ 4] because F508delCFTR generates apparently unconnected phenotypes such as channelopathies [ 5], dysfunctional pathogen sensing [ 6] and frustrated autophagy [ 7, 8].
However, much variation exists in the way CRC is managed both internationally [ 2, 3], and nationally within France [ 4- 6], due partly to specific treatment modalities and their conformity to guidelines, and to structural factors such as accessibility, or to doctors' willingness and competencies [ 7].
However, much uncertainty still exists about the electron fluxes from the electrode to the final electron acceptor sulfate during autotrophic sulfate reduction.
Widespread use in physicians' offices of a system like Vista would, in spite of some obvious advantages, further erode however much confidentiality still exists in the doctor-patient relationship.
However, much uncertainty still exists on how the relationships between physical properties of urban environments and ecological function of urban vegetation change over time with the dynamics of urban landscapes, and how they vary across different metropolitan areas of the world.
While the functional significance of the DRD4 VNTR polymorphism has not been definitively characterized, long alleles (typically 7R as opposed to 4R) might be functionally less reactive based on in-vitro expression experiments [ 20- 24], however much heterogeneity still exists [ 76- 80].
