An estrus synchronization protocol (7-11 Synch) was developed to synchronize the first follicular wave and timing of ovulation in postpartum beef cows. In Exp. 1, follicular development and timing of ovulation in response to the following protocol were evaluated. Beef heifers (n = 12) and cows (n = 6), at random stages of the estrous cycle, were fed melengestrol acetate (MGA; .5 mg x animal(-1)...

Process variation is becoming a primal concern in timing closure of LSI (Large Scale Integrated Circuit) with the progress of process technology scaling. To overcome this problem, SSTA (Statistical Static Timing Analysis) has been intensively studied since it is expected to be one of the most efficient ways for performance estimation. In this paper, we study variation of output transition-time....

OBJECTIVE The aim of this randomized, double-blind, placebo-controlled study was to evaluate the effect of ephedrine pretreatment on the intensity of rocuronium injection pain when rocuronium was applied by timing principle and also to compare this effect with lidocaine and placebo. SUBJECTS AND METHODS 120 American Society of Anesthesiology risk score I-II patients scheduled for elective sur...

Adenosine is a known inhibitor of respiratory output during early life. In this study we investigated the developmental changes in adenosine A2A-receptor activation on respiratory timing, as well as the relationship between adenosine and GABA. The specific adenosine A2A-receptor agonist CGS-21680 (CGS) or vehicle control was injected into the fourth ventricle of 14-day (n = 9), 21-day (n = 9), ...

The preparation of air–fuel mixture is considerably dependent on fluid flow dynamics to achieve improved performance, efficiency, and engine combustion in the appearance of flow. In this study, the effects of mixtures of hydrogen and compressed natural gas (CNG) on a spark ignition engine are numerically considered. This article presents the results of a direct-injection engine using methane–hy...

Computational fluid dynamics (CFD) is being increasingly used to analyse gasoline direct injection (G-DI) combustion systems in the early stages of design and development. Consequently, it is important to ensure that the CFD codes are both fast and accurate. The objective of the work presented in this article was to validate the new, advanced boundary motion capability of VECTIS which is built ...

Time-triggered systems require a very high degree of temporal accuracy at critical stages during run time. While many software fault injection environments exist today, none of these make provisions to meet the timing requirements of such sys-

Objective To use velocity encoded phase contrast MRI to determine timing of peak myocardial blood flow to establish when CMR stress perfusion imaging should be performed after injection of regadenoson.

Because of the most common method of preparing the fuel-air mixture for gasolinefueled engines is port fuel injection (PFI). For reducing the wall-film entering the cylinder in liquid phase, the phenomena of wall-film entering the cylinder in liquid phase should be at minimum lever or be avoided. So the first thing for learning the wall-film is to detect the way of the wallfilm entering the cyl...

Large-eddy simulation (LES) of multiple-injection spray combustion under engine-like conditions is performed using a coupled model an Eulerian stochastic field transported probability density function (ESF T-PDF) and flamelet generated manifold (FGM). This allows the use T-PDF methods in modeling interaction turbulence chemistry at affordable computational costs for engine applications. Simulat...
