In the present study, we focused on the rostral ventrolateral medulla as a possible site of action for kinins because of its established importance in the central regulation of the cardiovascular system. Unilateral microinjections of 100 pmol to 4 nmol bradykinin into the rostral ventrolateral medulla produced dose-dependent increases in mean arterial pressure in Sprague-Dawley (SD) rats, Wista...

Bachmann, O., T. Sonnentag, W.-K. Siegel, G. Lamprecht, A. Weichert, M. Gregor, and U. Seidler. Different acid secretagogues activate different Na1/H1 exchanger isoforms in rabbit parietal cells. Am. J. Physiol. 275 (Gastrointest. Liver Physiol. 38): G1085–G1093, 1998.—Rabbit parietal cells express three Na1/H1 exchanger isoforms (NHE1, NHE2, and NHE4). We investigated the effects of carbachol,...

We provide a generalization of Hoeeding's inequality to partial sums that are derived from a uniformly ergodic Markov chain. Our exponential inequality on the deviation of these sums from their expectation is particularly useful in situations where we require uniform control on the constants appearing in the bound.

The dynamic topology of ad hoc networks makes route discovery and reconstruction a non-trivial task. In this work we propose the use of mobility prediction to assist in ad hoc routing. A method of route discovery and route reconstruction using the sectorized mobility prediction technique is presented. Simulation and analytical results of the proposed routing strategy find it to offer considerab...

The effect of adding Frigate (R), an adjuvant developed primarily for use with the isopropylamine salt of glyphosate (Roundup)," to improve the eradication of ratoon sugarcane under minimum tillage is discussed. Results are presented from replicated trials conducted over three seasons evaluating the effects on cane regrowth of adding Frigate to recommended and low rates of Roundup. Results are ...

The objective of this study was to evaluate and compare the erosion rates generated by two types hand tools for small-scale tillage on a hillslope, using experimental tests Universal Soil Loss Equation (USLE). evaluated were conventional hoe redesigned furrowing hoe. work conducted in 145 m2 plot with an average slope 45% Colombia. Three treatments evaluated: a) Zero no herbicide (control); b) ...
