The effective modeling of fresh cementitious materials during setting is an active and challenging research topic. material behavior as well the parameters properties are not fully understood yet. Therefore, flow casting subject ongoing research. Previous works attempted to model cement paste a solid subjected yielding, or fluid modeled by Brinkman law power law, both in 2D 3D. Of existing mode...

In the present study, static characteristics of hydrodynamic circular journal bearings finite length are highlighted, using combined influences textured surface and non-Newtonian lubricants behavior, obeying to Rabinowitsch fluid model. The associated nonlinear Rabinowitsch-Reynolds equation has been discretized differences scheme solved by mean Elrod’s algorithm taking into account presence cy...

Nowadays many studies have focused on food waste. With an expanding population and a wide variety of foods, the sector is always expanding. In addition to production, there also increase in development These wastes result economic difficulties, environmental damage, loss priceless chemical components. The processing fruits vegetables generates most Quince fruit that difficult consume directly u...

Drilling mud is a necessary component of drilling operations. There have been notable attempts to enhance the filtration and rheological properties increase cutting carrying capacity water-based (WBM) using nanoparticles (NPs). This study investigates how varying Al2O3 concentrations affect fluids. In this study, different muds were produced bentonite (2.8g) without nanoparticle, 50% (1.4g) Al2...

This article explores the role of shear-thinning, pseudoplastic non-Newtonian fluids in causation fatal accidents involving hazardous atmospheres. Analysis indicates an appreciable likelihood occurrence structures infrastructure. When subjected to a shear force, such as stirring, stored gas emits from these fluids. Depending on gas, lethal concentrations can develop almost instantaneously. Upon...

The proposed study aims to develop and optimize a topical formulation with Castanea sativa shells extract considering the concept of Quality by Design, focusing on planned development that consider vulnerabilities entire process through risk analysis tools design experiments (DoE). A Box–Behnken three factors levels was used as statistical tool for execution DoE response surface methodology res...

An exopolysaccharide (EPS) producing strain CC30 was isolated from raw milk and identified as Streptococcus thermophilus with morphological and 16S sequencing analysis. The strain was shown to produce 1.95 g/L of EPS when grown in skim milk lactose medium at 30°C by increasing the viscosity of the medium. The EPS was isolated and purified, and it was shown to consist of glucose and galactose in...

The purpose of this study was to develop a pH-triggered in situ gelling vehicle for ophthalmic delivery of puerarin. The effect of hydroxypropyl-beta-cyclodextrin (HP-beta-CD) on the aqueous solubility and in vitro corneal permeation of puerarin was also investigated. The puerarin solubility increased linearly and proportionally to the HP-beta-CD concentrations and 5% (w/v) HP-beta-CD enhanced ...

The effect of two novel hydrocolloids known as Balangu seed gum (BSG) and palmate-tuber salep (PTS) with carboxymethylcellulose (CMC) on the rheological characteristics of a typical soft ice cream was studied. The power law model well described the flow behavior of mixes with a high correlation coefficient (r). The flow behavior index was in the range of 0.450-1.154, while the consistency coeff...

An accurate and detailed knowledge of the consistency 1 of the cytoplasm of different regions of the ameba during locomotion would seem to be of primary importance in understanding the mechanism of ameboid movement. Unfortunately, no such knowledge exists. In fact, it will be shown in this and in succeeding papers that the rheological information now available on ameba cytoplasm is at best frag...
