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,

Recent Advances in Mechanics of Non-Newtonian Fluids

open access: yesFluids, 2020
Flow of non-Newtonian (non-linear) fluids occurs not only in nature, for example, mud slides and avalanches, but also in many industrial processes involving chemicals (polymers), biological materials (blood), food (honey, ketchup, yogurt), pharmaceutical

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 ...

Redefining risk: Human rights and elementary school factors predicting post-secondary access

open access: yesEducation Policy Analysis Archives, 2020
While there is a widespread consensus that students’ pathways towards postsecondary education are influenced early in life, there is little research on the elementary school factors that shape them.

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

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?
