DEEP DEGASSING AS THE LEADING ENDOGENOUS PROCESS

Development of an automatic vacuum degassing system and parameters optimization for degassing process

Rapid tooling technology is regarded as an important method of reducing the cost and time to market in a new product development process. Silicone rubber mold is frequently used in indirect tooling. Automatic vacuum casting system is widely used to degas in the manufacturing of silicon rubber mold, but the cost of hardware is very expensive. A low-cost automatic vacuum degassing system is desig...

Influence of degassing on hot-melt extrusion process.

The present study aimed to evaluate the effect of degassing on an extrusion process, with respect to extrudate quality and drug release properties. Processed formulations were extruded with and without a degassing vent port at various locations along the barrel. All the experiments were performed under constant processing temperature, feeding rate, and screw speed. During the extrusion process,...

degassing in the Oregon Cascades

The carbon isotope content of dissolved inorganic carbon was measured for large cold springs in the central Oregon Cascades. Low 14C activities in some of the springs are interpreted to result from the dissolution of diffuse emissions of magmatic CO2, even though volcanic activity has not occurred in this area for more than 1300 yr. On the basis of dissolved magmatic carbon concentrations in th...

Two Paradigms of Endogenous Development: Production Process & Supply-demand Relationship

Different world views and philosophies in defining development problems and their solutions derive currently from different disciplines. They refer in many respects to the principle of cause-effect as a fundamental relationship between phenomena. The history of differing values and attitudes presented in management and design indicates the importance of this relationship. This sort of knowledge...
