Flow property testing is important in the design of handling equipment for bulk solids and the Jenike shear tester is a common and reliable method for ensuring flow from hoppers under the force of gravity alone. The Jenike shear test procedure has various stages and is known to have issues with operator dependency, questions have also been raised regarding the stress state within the shear cell. Currently the data for high pressure flow functions, which are applicable to large capacity storage f...

In open-pit mining operations, a larger energy consumption comprises the comminution processes. Therefore, blasting operations for rock fragmentation contribute to improving comminution efficiency, particularly in hard rock mines. Several factors control rock fragmentation pertaining to blasting and

This free daily journal provides updates on the latest industry developments and IDTechEx research on off-grid power generation including renewable and independent energy sources.

The fate of plastics entering the 3D ocean circulation from rivers discharge is examined through the Lagrangian analysis of neutrally buoyant particles. Particles are released continuously over 1991-2010 at the surface along the coasts according to monthly estimates of rivers plastic waste input. They are advected by daily currents from a state-of-the-art global ocean model at 1/12° resolution. At the end of the simulation, particles remaining in the surface layer of 1~m thickness represent...

Numerical modelling has been widely used in the underground excavation design, where the in situ stress state plays a crucial role in the stability analysis. However, determination of an exact stress state for a specific geological region remains uncertain due to the complicated tectonic nature and measurement limitations. The stability is thus better analysed by considering the in situ stress as a finite spectrum and pinpointing the possible worst-case scenario. The most probable scenarios of i...

With the increasing demand for light weight design in industries such as aerospace and automotive, sheet metallic materials with high strength and low density have been intensively manufactured and widely applied. However, plastic deformation induced surface roughening is an undesirable and a practically unavoidable phenomenon for sheet metallic materials and becomes the subject of great attention in recent years. The evolution of surface roughening plays important roles in the strain limit of t...

The paper will provide an overview of the currently applied engineering approach in the industry for curved hot bent glass in the absence of standards and codes.

The government on Wednesday approved continuation of an umbrella scheme, at an estimated cost of Rs 2,135 crore, for R&D into weather and climate services, improved forecast, and better early warnings among several other things, in the next ...
