Model-Free trajectory planning for a rotary-wing unmanned aerial vehicle with an uncertain suspended payload [PDF]
MATEC Web of Conferences, 2023 Payload transport using rotary-wing unmanned aerial vehicles (RUAVs) has grown in popularity. Suspending the payload from the RUAV expands the range of use cases but does so at the expense of changing the dynamics that may result in instability.

CLAYS AS SUSPENDING AGENTS FOR THORIA SLURRIES [PDF]
, 1957 Montmorillonite and attapulgite, in concentrations of 3% and above, are very effective in the retardation of settling of ThO/sub 2/ slurries and in the prevention of hardcaked sediments. The most useful material found was attapulgite sold under the trade name of Zeogel. Concentrations of 3% were very effective and 5% were even more so. Viscosity of the

Comparison of physical properties of extemporaneous oral suspension with suspending agent pulvis gummi and xanthan gum using paracetamol as model drug [PDF]
BIO Web of ConferencesContemporary paracetamol suspensions are made because some drug-active substances have a solubility that is practically insoluble in water but is needed in liquid form. Suspending agent is required to increase the low viscosity to prevent cake. Therefore,
