The low thermal conductivity of conventional heat transfer fluid has been a serious impediment for improving the performance and compactness of engineering equipments.
It is well known that most produced CNTs contain some impurities such as amorphous carbon, fullerenes, and catalyst particles that could significantly affect the CNT properties, which are a serious impediment for CNTs to be directly used as functional filler in composites.
Self-quenching may result in either a decrease or increase in fluorescence lifetime, and could become a serious impediment for [Hb] measurements.
Further, stigma and discrimination have been reported as factors constituting a serious impediment for VCT uptake and HIV prevention in Nigeria [ 29] and elsewhere [ 30].
However, the dissemination of the viral vector and its encoded gene product could be a serious impediment for vectors that encode cytokine genes, such as IFNγ, that are not only expressed in situ, but also secreted into the system and have considerable normal tissue toxicity [ 17- 20].
In solving this problem in the context of non-linear finite element reliability analysis, two serious impediments are encountered: (a) for certain material models, the constraint function may have a discontinuous gradient, leading to failure of the search algorithm to converge.
