ENGINE COMBUSTION EFFICIENCY AND PERFORMANCE OF EXHAUST PIPE FUEL PREHEATING SYSTEM


CHAIN EXTENDER AND EMULSIFIER APPLICATION IN IRON ORE FLOTATION

The present study aims to evaluate the reverse flotation performance of iron ore, using collector (amine), in the presence Shirt and absence of chain extender (diesel oil) and emulsifier (sodium lauryl sulfate).Six tests were realized with duplicate.Tests using amine, diesel oil and sodium lauryl sulphate show the better results, with metallurgical

Spinal Anesthesia Using Chloroprocaine is Safe, Effective, and Facilitates Earlier Discharge in Selected Fast-track Total Hip Arthroplasty

Background: Spinal anesthetic choice plays an underappreciated role in total hip arthroplasty (THA).Chloroprocaine, a short-acting local anesthetic, has been limited to short-duration ambulatory procedures and has not been studied in THA.We compare perioperative outcomes of patients undergoing fast-track THA using chloroprocaine spinal anesthesia w

Multiscale Applications of Two Online-Coupled Meteorology-Chemistry Models during Recent Field Campaigns in Australia, Part II: Comparison of WRF/Chem and WRF/Chem-ROMS and Impacts of Air-Sea Interactions and Boundary Conditions

Air-sea interactions play an important role in atmospheric circulation and boundary layer conditions through changing convection processes and surface heat fluxes, particularly in coastal areas.These changes can affect the concentrations, distributions, and lifetimes of atmospheric pollutants.In this Part II paper, the performance of the Weather Re
