High-pressure air cold-launch can provide advantages for commercial launches, from both safety and cost considerations. In military applications, missiles' structures are solid to be accelerated more than 10g by engine exhaust flow. The critical part of implementing commercial systems is precisely controlling energy-releasing from the high-pressure …

pressure in CO2 HPWH without high pressure control. By modeling a running CO2 HPWH, we in-depth investigated the relationship between optimal high pressure and refrigerant charge. It was found that for practical systems, the essence of optimal high pressure control is to manage optimum refrigerant charge of the system. If the optimum …

the utilization of high pressure grinding rolls, HPGR, crushers. (Rule, Smit, Cope and Humphries 2008). This has occurred within an overall focus on process control and stability enhancement of the concentrator flow-sheets for these new comminution technologies. This has also led to the development of some unique circuits where

Polymyxins have remained the drug of choice for treatment due to carbapenem-resistant Gram-negative bacilli. Unfortunately, the utility of these agents has been limited by a lack of pharmacokinetic understanding, a high toxicity rate, and an extremely narrow therapeutic index. Significant advancements have been achieved in the understanding of ...

An important aspect in the performance of the high pressure grinding rolls (HPGR) is its throughput. The HPGR throughput can be changed by varying the speed of the rolls, but, it is important to determine the effects of changes in the rolls speed together with other variations such as grinding force and feed size, on the overall performance of …
