Stringiness of hyaluronic acid emulsions. [PDF]
Int J Cosmet Sci, 2021 Cosmetic emulsions containing hyaluronic acid are ubiquitous in the cosmetic industry. However, the addition of (different molecular weight) hyaluronic acid can affect the filament stretching properties of concentrated emulsions. Here, we find that high molecular weight hyaluronic acid and a high stretching speed are the control parameters affecting ...

The role of ascitic fluid viscosity in the differential diagnosis of ascites. [PDF]
Can J Gastroenterol, 2010 BACKGROUND: Ascites is defined as the pathological accumulation of fluid in the peritoneal cavity. It is the most common complication of cirrhosis, which is also the most common cause of ascites. Viscosity is a measure of the resistance of a fluid to deform under shear stress.

Functional restoration of the spine: effect of initial pain level on the performance of subjects with chronic low back pain. [PDF]
Pain Res Manag, 2014 BACKGROUND: Chronic low back pain is a persistent lumbar pain of multifactorial origin. The initial pain level remains poorly used to analyze and compare responses in low back pain patients in a reconditioning program. OBJECTIVE: To assess and evaluate the responses of subjects with very painful chronic low back pain in a dynamic and intensive care ...

Perspectives of Earth and Space Scientists, Volume 1, Issue 1, 2020., 2020 Abstract Plate tectonics, one of the greatest scientific discoveries of the twentieth century, works particularly well in oceanic regions but has considerable difficulty to account for widespread, diffuse deformation of the continents. There has been an enduring discourse on whether continuous deformation of the crust or slip along discrete faults is a

CISAILLEMENT ADIABATIQUE : INFLUENCE D'UNE PRÉDÉFORMATION
Le Journal de Physique Colloques, 1985 Nous présentons les résultats expérimentaux concernant la rupture par cisaillement adiabatique en compression dynamique d'échantillons prédéformés en alliage de titane TA6V et en acier 35NCD16 de structure martensitique. La prédéformation faisant varier le coefficient de consolidation n, nous étudions l'évolution de la déformation à rupture en fonction

Texture, Stress, and Microstructure, Volume 22, Issue 4, Page 233-260, 1994., 1994 Discrete methods of orientation distribution (ODF) analysis are applied to quartz and calcite rocks with trigonol crystal and triclinic sample symmetry. ODF’s are calculated from pole figures measured by neutron diffraction. A particular complication for quartz is the presence of overlapping peaks which can be separated with the WIMV or ADC algorithms ...

Comportement au cisaillement d’un joint rocheux naturel [PDF]
Revue Française de Géotechnique, 2009 Discontinuities are of major importance considering the stability of rock masses. Different experimental and numerical methods can be used for their study. As the « blue book » of the International Society of Rock Mechanics (ISRM, 2007) is republished, it is particularly relevant to wonder about the best procedures to characterize the behaviour of the ...
