BALANCED SLIDE-VALVES. (INCLUDES PLATE).

Simian virus 40 infection triggers a balanced network that includes apoptotic, survival, and stress pathways.

The infection process by simian virus 40 (SV40) and entry of its genome into nondividing cells are only partly understood. Infection begins by binding to GM1 receptors at the cell surface, cellular entry via caveolar invaginations, and trafficking to the endoplasmic reticulum, where the virus disassembles. To gain a deeper insight into the contribution of host functions to this process, we stud...

Analysis of the Motion of Plate Type Suction or Discharge Valves Mounted on Reciprocating Pistons

The equations of motion of plate type suction and discharge valves mounted on reciprocating pistons are given. Their solutions by modal series expansion are discussed and finally given in a form that conforms to the notation and approach used in previous work. Using the definition of an equivalent pressure, it is shown that both types of valves are assisted in closing, which may result in prema...

Liquid Encapsulation in Parylene Microstructures Using Integrated Annular-Plate Stiction Valves

We report the design, fabrication and characterization of micromachined Parylene structures for self-sealing liquid encapsulation applications. Automatic sealing is enabled through the use of an integrated annular-plate stiction valve which greatly reduces device footprint over in-plane configurations. We achieve automatic wafer-level liquid entrapment without using adhesives or processing at e...
