From 1989 until his funding was terminated in 1995, Melvin Miles performed some of the best cold fusion experiments on record, at the China Lake Naval Air Warfare Center. (He retired from China Lake in 2002.) His goal was to answer two critical questions: Does cold fusion produce helium along with excess heat, like a plasma fusion reaction? And if so, does it produce roughly as much helium per ...

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Lipid membrane fusion is critical to cellular transport and signaling processes such as constitutive secretion, neurotransmitter release, and infection by enveloped viruses. Here, we introduce a powerful computational methodology for simulating membrane fusion from a starting configuration designed to approximate activated prefusion assemblies from neuronal and viral fusion, producing results o...

We discuss the reaction rate of the muon-catalysed t-t fusion. The reaction rate is determined as a function of the temperature using the model of “in flight” fusion. We especially take into account the effect of the fluctuation of the cross section due to the existence of the muon. The obtained reaction rate 5.0×10−3μs−1 is a factor of 10−3 smaller than the experimental muonic cycling rate in ...

Abstract This chapter introduces the reader to fundamentals and reasoning for exploring fusion energy. Fusion, reaction of two hydrogen atoms colliding, is process that powers Sun stars. Fusion works by turning small amounts matter into vast If realized on Earth, nuclear could solve global energy demands generations come.

Membrane fusion events are required in three steps in sea urchin fertilization: the acrosome reaction in sperm, fusion of the plasma membrane of acrosome-reacted sperm with the plasma membrane of the egg, and exocytosis of the contents of the egg cortical granules. We recently reported the involvement of a Zn2+-dependent metalloendoprotease in the acrosome reaction (Farach, H. C., D. I. Mundy, ...
