The rheological behavior is known to be of great interest in sludge treatment, but the material complexity induces strong measurement difficulties. The literature highlights two characteristics deeply impacting sludge rheological properties and their characterization: Thixotropic behavior and organic matter (Seyssiecq et al., 2003; Eshtiaghi et al., 2013), both being related to each other. Indeed, by looking at how thixotropy affects elastic modulus and yield stress with different mechanical histories at different organic matter ratios, it turns out that the higher the organic matter, the higher the thixotropic behavior.

The initial pH value of sludge affects sludge anaerobic digestion and dewatering performance. In order to determine the suitable pH value and decrease the sludge digestion time, in this study, the eff...
Rheological properties are important in the design and operation of sludge-handling process. Despite this, the rheology of sludge in thermal hydrolysis processes (TH) is not well described. In-situ me...
The efficiency of barier creams (BC) in the prevention of occupational skin diseases is closely related to their mechanical, rheological but also sensory properties. The measurement procedure we elabo...
The pyrolysis kinetics of sewage sludge was studied to determine the constituent of sludge and explore the feasibility of pyrolytic post-treatment. Both flocculent sludge and granular sludge were pyro...
Mucus is a biomaterial with peculiar, gel-like viscoelastic properties, and bearing different functionalities, depending on the different mucosae it covers. It is clear that these functionalities have...
This is a proof of concept study. The aim of this study is to assess a device measuring rheological properties of human sputum of four populations : - 10 patients with Broncho Chronic ...
The purpose of this study is to measure the mechanical properties of healing Achilles tendons in humans after early controlled weightbearing, compared with a control group in a randomized,...
It has been suggested that dietary fibers can affect food intake and satiation. Satiation, or meal termination, can be induced by sensory properties and energy density of fiber-rich food p...
The objective of this study is to quantify the mechanical environment of pregnancies complicated by a short cervix and randomized in the Trial of Pessary in Singleton Pregnancies with a Sh...
Low back pain is a major cause of disability, especially in the working-age population. A total of 149 million working days are lost every year as a consequence of back pain. Intervertebra...
The conformation, properties, reaction processes, and the properties of the reactions of carbon compounds.
The properties and processes of materials that affect their behavior under force.
A historical and cultural entity dispersed across the wide geographical area of Europe, as opposed to the East, Asia, and Africa. The term was used by scholars through the late medieval period. Thereafter, with the impact of colonialism and the transmission of cultures, Western World was sometimes expanded to include the Americas. (Dr. James H. Cassedy, NLM History of Medicine Division)
The properties, processes, and behavior of biological systems under the action of mechanical forces.
The study of literature in its widest sense, including grammar, etymology, criticism, literary history, language history, linguistic history, systems of writing, and anything else that is relevant to literature or language viewed as literature. Philology as a discipline has both philosophical and scientific overtones.
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
