Title          
Banked blood doesn't deliver oxygen 
   
 
Abstract    

Main Article from Howard Hughes Medical Institute

Blood flow in the microcirculation is regulated by physiological O2 gradients that are coupled to vasodilation and vasoconstriction, but the mechanism underlying this fundamental vascular response (which controls O2 delivery to tissues) has remained a major unanswered question in vascular physiology. The discovery of a previously unknown S-nitrosothiol (SNO) derivative of hemoglobin that has potent vasodilatory activity has changed the picture. Most significantly, the affinity of cysteine β93 for NO is high in the R (or oxy) structure and low in the T (or deoxy) structure. Thus, deoxygenatio...

Title          
High voltage disconnect switch 
   
 
Abstract    

An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Electric power may flow through several substations between generating plant and consumer, and may be changed in voltage in several steps.

A substation that has a step-up transformer increases the voltage while decreasing the current, while a step-down

Title          
MathCad Demo 
   
 
Abstract    

Mathcad is desktop software for performing and documenting engineering and scientific calculations. First introduced in 1986 on MS-DOS, it was the first to introduce live editing of typeset mathematical notation, combined with its automatic computation. It was also the first to automatically compute and check consistency of engineering units such as the International System of Units (SI). Mathcad today includes some of the capabilities of a computer algebra system but remains oriented towards ease of use and numerical engineering applications. Mathcad was conceived and originally written by Allen Razdow (of MIT), co-founder of Mathsoft which is now part of

The Elegant Universe : Can String Theory dete... 
   
 
Abstract    

Where could God be? Why cant we see Him? Can modern technology detect God?String Theory holds the answer!

String theory is a still-developing mathematical approach to theoretical physics, whose original building blocks are one-dimensional extended objects called strings. Unlike the point particles in quantum field theories like the standard model of particle physics, strings interact in a way that is almost uniquely specified by mathematical self-consistency, forming an apparently valid quantum theory of gravity.

Since its birth as the

Title          
The Elegant Universe - Einstein's Relativity 
   
 
Abstract    

Einstein's General Theory of Relativity explained.

Special relativity (SR) (also known as the special theory of relativity (STR)) is the physical theory of measurement in inertial frames of reference proposed in 1905 by Albert Einstein (after considerable contributions of Hendrik Lorentz and Henri Poincaré) in the paper "On the Electrodynamics of Moving Bodies".[1]...

Title          
Autonomous Vehicle Lab, U. of Maryland 
   
 
Abstract    

Robot vehicles modeled after insects. By Joe Conroy and Andrew Hyslop.

The notion that small, even very small, UAVs might have practical uses arose in the early 1990s. In 1992, DARPA conducted a workshop titled "Future Technology-Driven Revolutions In Military Operations". One of the topics in the workshop was "mobile microrobots". The idea of using very small "microdrones" was discussed, and after initial skepticism the idea started to gain momentum.

The RAND Corporation released a paper on the microdrone concept in 1994 that was widely circulated. DARPA conducted a series of "paper studies" and workshops on the concept in 1995 and 1996, leading to early engineering studies by the Lincoln Laboratories at the Massachusetts Institute of Technology (MIT), and the
