Right coronary (RC) autoregulation and right ventricular (RV) function were assessed in conscious dogs, chronically instrumented to measure RC flow and RC pressure (RCP) as a hydraulic occluder on the RC was inflated. Dogs were then anesthetized, and RC autoregulation and RV function were again assessed. In the conscious state, moderate RC autoregulation was present with closed loop gains (Gc) ...

BACKGROUND Radical cystectomy (RC) represents the mainstay of treatment in patients with muscle-invasive urinary bladder cancer but how it compares with the best organ preservation approach is not known. MATERIALS AND METHODS The objective of our review is to compare the 5-year overall survival (OS) rates from retrospective and prospective studies of RC and trimodality treatment (TMT), i.e. c...

Shape memory alloys (SMAs) are unique smart materials that have many advantages, such as ability to resist large strains without leaving residual strains and ability to recover original form. However, the high costs of SMAs have limited their usage. This paper evaluates the behavior of concrete structures equipped with SMAs in an optimal manner as they are being used along the plastic hinge of ...

This paper addresses the stress field of reinforced concrete (RC) beam–column joints retrofitted with haunches. Design such solution currently assumes internal forces evaluated by so called β-factor approach, which was originally conceived targeting enhancement steel moment-resisting frames. Extension to RC is subsequent as it emerges from literature survey. The analytical model first criticall...

We classify practical replica control (RC) mechanisms according to two main criteria: (1) the abstract RC protocol, e.g., how many physical copies are written for a logical update, and (2) the kind of integration between the RC mechanism and system services such as atomic broadcast, commit protocols, and concurrency control. We describe about a dozen representative RC mechanisms (most of them i...

1. RECAPITULATION Part I of this article treats tense in relative clauses (RCs) in English, Russian and Japanese. The temporal centre in RCs can always be Tproi, and sometimes it has to be Tproi. 1. In SOT languages such as English, the Tense in the RC is bound in RC\wollconfigurations, i.e., we find a Tproi bound by woll. The licensing of the morphological tense in the RC is non-local in these...

progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

X-ray structures of five bis(N — R-salicylaldiminato)zinc(II) complexes with R — ethyl, «-propyl, /-propyl, «-butyl and 4-thia-rc-hexyl were determined. The N202 coordination geometry is in all cases gwas/-tetrahedral with the dihedral angle between the planes of the two chelate rings ranging from 84 to 89°. Bond lengths and angles in the coordination sphere are not affected by the nature of R ...

In the paper a remote lab experiment RC oscillator used to support Web based learning, to support learning by doing, to learn control design and to minimize the gap between theory and practice is presented. The experiment was designed with a special care for visualisation of important control design parameters in Bode plot and Root-Locus diagram. The experiment is based on MATLAB, LABview and D...
