Enhanced myocardial protection with adenosine
The Annals of Thoracic Surgery, 1989This study was undertaken to investigate whether adenosine administered during cardioplegic arrest could enhance myocardial protection and improve recovery of function after ischemia. Isolated perfused rabbit hearts were subjected to 120 minutes of hypothermic (32 degrees C) multidose cardioplegia-induced ischemia.

Exercise Enhances and Protects Brain Function
Exercise and Sport Sciences Reviews, 2002Physical activity, in the form of voluntary wheel running, induces gene expression changes in the brain. Animals that exercise show an increase in brain-derived neurotrophic factor, a molecule that increases neuronal survival, enhances learning, and protects against cognitive decline. Microarray analysis of gene expression provides further support that

While Asian governments have for some time pursued high rates of growth as their primary economic goal, provision of social protection tended to be viewed as an expensive luxury that only rich economies can afford. Most Asian governments, while maintaining a few social programs to assist very poor and disadvantaged groups, have generally considered ...

Static Relay Permit Enhanced Protection
IEEE Industry Applications Magazine, 1999Multi-function multi-phase static overcurrent relays, using digital technology available today, provide basic time, (51) (51G) (51N) and instantaneous (50) (50G) (50N) three phase and ground overcurrent protection, and may offer some or all of the following additional functions: undervoltage (27); overvoltage (59); reverse phase sequence (47); negative

Enhanced double circuit line protection
Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering, 2002This paper describes a double circuit line protection relay which has all 6 line currents and voltages available for processing. Results are presented for the relay fed with simulated waveforms from a Playback Simulator. The system used in the simulations is modelled on a 69 kV parallel line in the Winnipeg Hydro network.

Topologically protected sound enhancement
Applied Physics LettersThe pursuit of robust and enhanced acoustic sensing has garnered significant attention across multiple fields of acoustic engineering. Here, we propose a feasible approach to realizing sound energy enhancement along the interface of two topologically distinct materials in an acoustic topological waveguide (ATW) with a gradient gap width.

Enhanced Numerical Breaker Failure Protection
IEEE Transactions on Power Delivery, 2008Breaker failure (BF) protection provides backup for circuit breakers (CBs) and associated control wiring. Traditionally, CBs are not duplicated, but monitored by BF relays when ordered to trip. Upon a failure of a breaker to interrupt the current, the BF relay opens adjacent breakers to isolate the problem.

Protecting and Enhancing American Security
2023Abstract UNCLOS enhances American security in multiple ways. These include enhanced navigational regimes in the territorial sea, through straits and archipelagoes, and full protection of navigational freedom in the 200-mile economic zone and on the high seas.

Protecting and Enhancing American Sovereignty
2023Abstract This chapter describes how the UNCLOS Convention protects and expands American sovereignty. Thus, the Convention creates a new area of United States sovereign rights over natural resources of the seafloor and water column to 200 nautical miles off America’s coasts, and it massively expands the legal continental shelf of the ...
