Hydrodynamic fluctuations and instabilities in ordered suspensions of self-propelled particles [PDF]

open access: yes, 2002
We construct the hydrodynamic equations for {\em suspensions} of self-propelled particles (SPPs) with spontaneous orientational order, and make a number of striking, testable predictions:(i) SPP suspensions with the symmetry of a true {\em nematic} are {\

Evaluation of the Physical Stability of Zinc Oxide Suspensions Containing Sodium Poly-(acrylate) and Sodium Dodecylsulfate. [PDF]

open access: yes, 2011
The physical stability of zinc oxide (ZnO) aqueous suspensions has been monitored during two months by different methods of investigation. The suspensions were formulated with ZnO at a fixed concentration (5 wt%), sodium poly-(acrylate), as a viscosifier,

Geometric Cone Surfaces and (2+1)- Gravity coupled to Particles [PDF]

open access: yes, 2000
We introduce the (2+1)-spacetimes with compact space of genus g and with r gravitating particles which arise by ``Minkowskian suspensions of flat or hyperbolic cone surfaces'', by ``distinguished deformations'' of hyperbolic suspensions and by ...

Parametrisation of a Maxwell model for transient tyre forces by means of an extended firefly algorithm

open access: yesAdvances in Mechanical Engineering, 2016
Developing functions for advanced driver assistance systems requires very accurate tyre models, especially for the simulation of transient conditions. In the past, parametrisation of a given tyre model based on measurement data showed shortcomings, and ...

Formulation optimization of the powder for suspension of flixweed seeds (Descurainia sophia L.), a Persian medicinal drink [PDF]

open access: yesVojnosanitetski Pregled
Background/Aim. Flixweed (Descurainia sophia L.) beverage has been used in Persian medicine as an effective remedy for constipation. Allyl isothiocyanate (AITC), the main ingredient of flixweed essential oil, has been claimed to regulate gastrointestinal

Suspension-to-suspension justification principles [PDF]

open access: yesBelgrade Philosophical Annual, 2020
We will be in a better position to evaluate some important skeptical theses if we first investigate two questions about justified suspended judgment. One question is this: when, if ever, does one justified suspension confer justification on another suspension? and the other is this: what is the structure of justified suspension?

Quasi-monolithic mirror suspensions in ground-based gravitational wave detectors [PDF]

open access: yes, 2018
At the commencement of a new era in astrophysics, with added information from direct detections of gravitational-wave (GW) signals, this paper is a testament to the quasi-monolithic suspensions of the test masses of the GW detectors that have enabled the
