The distribution of settling velocity of non-spherical mineral particles [PDF]

open access: yesActa Montanistica Slovaca, 2005
The settling velocity is an independent variable of the hydraulic separation performed for instance by means of jigs. Therefore, the settling velocity characterizes the material forwarded to the separation process.

The Potential of Phase-Doppler Anemometry

open access: yesKONA Powder and Particle Journal, 2014
Phase-Doppler anemometry (PDA) is a well-established optical measuring technique for the nonintrusive and simultaneous determination of size and velocity of spherical particles in various engineering processes.

Hydrodynamic interactions suppress deformation of suspension drops in Poiseuille flow

open access: yes, 2010
Evolution of a suspension drop entrained by Poiseuille flow is studied numerically at a low Reynolds number. A suspension drop is modelled by a cloud of many non-touching particles, initially randomly distributed inside a spherical volume of a viscous ...

Ketogenic Diet as an Epigenetic Therapy in SETD1B‐Related Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Histone lysine methyltransferases such as SETD1B regulate chromatin structure and gene transcription. Ketone bodies, including butyrate, act as histone deacetylase inhibitors. We report a 4‐year‐old boy with SETD1B‐related absence epilepsy, refractory to conventional medications, who achieved sustained > 90% seizure reduction on the Modified ...

Experimental and DEM based characterization of flowability of non-spherical and spherical bauxite particles

open access: yesScientific Reports
The flowability of granular bauxite materials critically affects the efficiency of industrial systems such as moving bed heat exchangers (MBHEs) in concentrated solar power (CSP) applications.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Statistics of Smoke Sphericity and Optical Properties Using Spaceborne Lidar Measurements

open access: yesRemote Sensing
Smoke particles from biomass burning events are typically assumed to be spherical despite previous observations of non-spherical smoke. As such, large uncertainties exist in some physical and optical parameters used in lidar aerosol retrievals, including

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

open access: yesAdvanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Modelling of non-metallic particles motion process in foundry alloys

open access: yesMetalurgija, 2015
The behaviour of non-metallic particles in the selected composites was analysed, in the current study. The calculations of particles floating in liquids differing in viscosity were performed.
