Agitator Trucks

Agitator trucks are specialized vehicles that transport and continuously mix fresh concrete, helping preserve its uniformity and workability between a batching plant and a construction site. A rotating drum uses angled internal blades to tumble the concrete, preventing segregation and premature setting while the truck travels; drum speed and rotation direction can be adjusted for mixing or discharge. In engineering, these trucks support the reliable placement of concrete for foundations, bridges, roads, buildings, and other large structures. Their mobile mixing capacity improves material consistency, reduces handling steps, and helps coordinate concrete delivery with demanding construction schedules.

2023

Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA Liquid-liquid extraction (LLE) is a separation technique used instead of distillation when either: (a) the relative volatilities of the compounds to be separated are very similar; (b) one or more of the mixture components are temperature sensitive even near ambient conditions; (c) the distillation would require a very low pressure or a very high distillate/feed...

2018

The power input in stirred bioreactors can be measured through the torque that acts on the impeller shaft during rotation. This manuscript describes how an air bearing can be used to effectively reduce friction losses observed in mechanical seals and improve the accuracy of power input measurements in small-scale vessels.

Protein Membrane Overlay Assay: A Protocol to Test Interaction Between Soluble and Insoluble Proteins in vitro

2011

Testing protein-protein interaction is indispensable for dissection of protein functionality. Here, we introduce an in vitro protein-protein binding assay to probe a membrane-immobilized protein with a soluble protein. This assay provides a reliable method to test interaction between an insoluble protein and a protein in solution.
