A commonly cited advantage of pulse combustors is a high rate of heat transfer in the tail pipe. Past research on these rates of heat transfer is inconclusive regarding the amount of heat transfer enhancement and how various flow parameters affect this enhancement. This article reports an experimental heat transfer study in the tail pipe of a pulse combustor. The pulsation frequency, pulsation ...

Within the context of predicting and mitigating flood hazards, this paper motivates the development of innovative ideas in three engineering research areas: (a) spatially-distributed quantitative rainfall prediction, (b) spatially-distributed flow prediction, and (c) long-term flow prediction for water resources management. Design, operational implementation, real-time testing, and training of ...

Monoclonal antibodies 50D6 and 21r5, reactive with human class II molecules, were analyzed quantitatively by flow cytometry and cellular radioimmunoassay for their binding to cells of different HLA-DR types. Monoclonal antibody 50D6 bound equally to cells of all DR types tested except DR7, where no reactivity was observed. Monoclonal antibody 21r5 was reactive with all cells. However, the perce...

The CA1-projecting axons of CA3 pyramidal cells, called Schaffer collaterals, constitute one of the major information flow routes in the hippocampal formation. Recent anatomical studies have revealed the non-random structural connectivity between CA3 and CA1, but little is known regarding the functional connectivity (i.e. how CA3 network activity is functionally transmitted downstream to the CA...

We describe an unexpected constitutive transition in entangled polymer solutions. At and beyond a critical stress, the initial spatially homogeneous and well-entangled sample transforms from its entangled (coiled) state into a fully disentangled (stretched) state over a period during which the resulting shear rate increases in a spatially inhomogeneous fashion. In the mode of controlled shear r...

Nucleotide diversity was examined at mitochondrial COI and r16S2 loci in eight Glossina swynnertoni Austen collections from northern Tanzania and from a culture maintained by the International Atomic Energy Agency. Eighteen composite haplotypes were observed among 149 flies, two of which were common to all samples and 10 were private. Mean haplotype diversity was 0.59 and nucleotide diversity w...

The study of water surface profiles is beneficial to various applications in resources management. In this study, two artificial intelligence (AI) models named the neural network (ANN) and genetic programming (GP) were employed estimate length six steady GVF for first time. AI trained using a database consisting 5154 dimensionless cases. A comparison was carried out assess performances techniqu...
