Title          
Hydraulic Model of Cardio Vascular System 
   
 
Abstract

Dr Anderson's patent on Extracorporeal heart can be found here

From Youtube - The video demonstrates the unique nature of the heart as a non-sucking pump, whose output is controlled by systemic factors, as opposed to pumps (such as standard roller pumps) that suck to fill, whose output is controlled by pump factors. It also shows the determinative effects of Mean Vascular Pressure, Inlet Impedance, and the critical role of the atrium on cardiac output. The resulting understanding is far more illuminating of the actual determinants of cardiac output than the emphasis on concepts like "stroke rate times stroke volume," preload, afterload, and contractility that dominates many basic physiology courses. Robert M. Anderson, MD (1920-2010) was Associate Professor of Surgery and Associate Dean of the University of Arizona College of Medicine in Tucson, Arizona, and a Fellow of both the American College of Cardiology and the American College of Surgeons.

Title          
Fish Inspired Wind Turbines 
   
 
Abstract
Excerpt from http://www.caltech.edu/article/13430 "The power output of wind farms can be increased by an order of magnitude—at least tenfold—simply by optimizing the placement of turbines on a given plot of land, say researchers at the California Institute of Technology (Caltech) who have been conducting a unique field study at an experimental two-acre wind farm in northern Los Angeles County. A paper describing the findings—the results of field tests conducted by John Dabiri, Caltech professor of aeronautics and bioengineering, and colleagues during the summer of 2010—appears in the July issue of the Journal of Renewable and Sustainable Energy."

Title          
IBM Research Computational Biology Center  
   
 
Abstract

Computational biology is an interdisciplinary field that applies the techniques of computer science, applied mathematics and statistics to address biological problems. The main focus lies in the development of computational and statistical data analysis methods and in developing mathematical modeling and computational simulation techniques. By these means it addresses scientific research topics with their theoretical and experimental questions without a laboratory. It is connected to the following fields: (1) Computational biomodeling, a field concerned with building computer models of biological systems.(2)

Title          
Nobel Laureate Venki Ramakrishnan: by Nature ... 
   
 
Abstract
Venkatraman "Venki" Ramakrishnan (Tamil: வெங்கட்ராமன் ராமகிருஷ்ணன்; born 1952 in Chidambaram, Tamil Nadu, India) is a structural biologist at the MRC Laboratory of Molecular Biology in Cambridge, England.[1] He shared the 2009 Nobel Prize in Chemistry with Thomas A. Steitz and Ada E. Yonath "for studies of the structure and function of the ribosome".[2] Venkatraman Ramakrishnan was born in Chidambaram in Cuddalore district of Tamil Nadu, India.[3] He moved to Baroda (Vadodara) in Gujarat state at the age of three, where he had his schooling, except for spending 1960–61 in Adelaide, Australia. Following his Pre-Science at the Maharaja Sayajirao University of Baroda, he did his undergraduate studies in the same university on a National Science Talent Scholarship, graduating with a B.Sc. in Physics in 1971. In a January 2010 lecture at the Indian Institute of Science, he revealed that he failed to get a seat at any of the colleges of the Indian Institutes of Technology, and Christian Medical College, Vellore, Tamil Nadu.[4] Immediately after graduation he moved to the U.S.A., where ...

Title          
Cavitation driven weapon for Pistol Shrimp 
   
 
Abstract
Acoustic weapon for Pistol Shrimp.The snapping shrimp competes with much larger animals, like the Sperm Whale and Beluga Whale, for the title of 'loudest animal in the sea'. The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures of up to 80 kPa at a distance of 4 cm from the claw. The pressure is strong enough to kill small fish. It corresponds to a zero to peak pressure level of 218 decibels relative to one micropascal (dB re 1 μPa), equivalent to a zero to peak source level of 190 dB re 1 μPa at the standard reference distance of 1 m. Au and Banks measured peak to peak source levels between 185 and 190 dB re 1 μPa at 1 m, depending on the size of the claw. Similar values are reported by Ferguson and Cleary. The duration of the click is less than 1 millisecond.

The snap can also produce sonoluminescence from the collapsing cavitation bubble. As it collapses, the cavitation bubble reaches temperatures of over 5,000 K (4,700 °C). In comparison, the surface temperature of the sun is estimated to be around 5,800 K (5,500 °C). The light is of lower intensity than the light produced by typical sonoluminescence and is not visi...

Title          
Circular bubbles produced by Whales and Dolph... 
   
 
Abstract
Circular bubbles produced by Whales and Dolphins. A bubble ring is an underwater ring vortex where an air bubble occupies the core of the vortex, forming a ring shape. The ring of air as well as the nearby water spins poloidally as it travels through the water, much like a flexible bracelet might spin when it is rolled off a person's arm. Some scuba divers can create bubble rings by blowing air out of their mouth in a particular manner. Long bubble rings also can form spontaneously in turbulent water such as in heavy surf. Bubble rings and smoke rings are both forms of vortex rings, and are sometimes studied in the field of fluid dynamics. Dolphins and humpback whales have also been seen to create bubble rings. Dolphins sometimes create bubble rings on purpose, seemingly for amusement.

Title          
Electric Eel 
   
 
Abstract

The electric eel or temblador (Electrophorus electricus), is an electrical fish, and the only species of the genus Electrophorus. It is capable of generating powerful electric shocks, which it uses for both hunting and self-defense. It is an apex predator in its South American range. Despite its name it is not quite an eel at all but rather a knifefish.

Electric eels have an elongated, cylindrical body, typically growing to about 2 m (about 6 feet) in length, and 20 kg (about 44 pounds) in weight, making them the largest species of the Gymnotiformes.
