Spreading and decay rates of several synthetic jets are experimentally measured up to 70–100 diameters (d) away from the orifice. It is found that, consistent with previous studies, after 10d–15d from the nozzle a synthetic jet displays a self-similar velocity profile together with enhanced spreading and decay behaviors than a continuous jet. However, this enhancement does not persist throughou...

Whenever any plant and/or herb is ingested, the body system interacts with it in an attempt to get rid of any harmful toxins such may contain, especially if the body cannot convert the foreign substance into useful components. This study was to evaluate the effects of oral consumption of aqueous leaf extract of Senecio biafrae on the histology of the frontal cortex, kidney, liver and testis of ...

Previous studies from this laboratory have shown that mitochondrial bound hexokinase is markedly elevated in highly glycolytic hepatoma cells (Parry, D. M., and Pedersen, P.L. (1983) J. Biol. Chem. 258, 10904-10912). A pore-forming protein, porin, within the outer membrane appears to comprise at least part of the receptor site (Nakashima, R.A., Mangan, P.S., Colombini, M., and Pedersen, P.L. (1...

The systemic inflammatory response syndrome (SIRS) is a potentially lethal response triggered by diverse forms of tissue injury and infection. When systemic inflammation is triggered by infection, the term sepsis is used. Understanding how inflammation is mediated and regulated is of enormous medical importance. We previously demonstrated that circulating inflammatory-relevant microRNAs (CIR-mi...

Laboratory rats traditionally are classified as nonphotoperiodic because variations in daylength have little or no effect on their gonadal function. After olfactory bulbectomy, however, rats show clear evidence of photoperiodic regulation of the gonads. The present study demonstrates, by means of resonance experiments, that the testicular response to daylength in rats is mediated by a circadian...

The dilution of lubricant due to contamination with diesel fuel is an increasingly prevalent, potentially important and poorly understood issue. This study addresses two fundamental questions: 1) How does the change in rheology affect engine lubrication? 2) chemical performance components (base oil additives) impacted by under different lubrication regimes (boundary/full film, hydrodynamic/elas...
