Mass movements in Brazil are common phenomena, especially during strong rainfall events that occur frequently in the summer season. These phenomena cause losses of lives and serious damage to roads, bridges, and properties. Moreover, the illegal occupation by slums on the slopes around the cities intensifies the effect of the mass movement. This study aimed to develop a methodology that combine...

The article provides a new definition of rheological similarity and thus a new basis for the modeling of non-Newtonian fluids: Fluids, whose rheological functions =f( ) can be twist-free shifted in a log/log field to a common master curve are rheologically similar and can be mutually used as model fluids in model experiments. This thesis is theoretically explained and confirmed by evaluation o...

The theological parameters of a clay suspension can be used to evaluate particle-particle interactions. Although there have been many studies of the rheological behavior of suspensions of reference clays, only few studies were performed with suspensions of mixed clays, and the rheological properties of these suspensions are not yet fully understood. The length-to-width ratio of some soil clays ...

Polyethylenes (PE) are the most commonly occurring ingredients for post-consumer recyclates (PCR). The structure–property relationships of different types model PE-based blends established using multiple thermo-rheological analyses. Although considered “simple”, complex behavior is experimentally demonstrated first time metallocene-catalyzed, linear, low-density polyethylenes (mLLDPE) with micr...

We show that besides simple or thixotropic yield stress fluids there exists a third class of yield stress fluids. This is illustrated through the rheological behavior of a carbon black suspension, which is shown to exhibit a viscosity bifurcation effect around a critical stress along with rheopectic trends, i.e., after a preshear at a given stress the fluid tends to accelerate when it is submit...

The motivation for this work is to propose a first thorough review of dough rheological models used in numerical applications. Although many models have been developed to describe dough rheological characteristics, few of them are employed by researchers in numerical applications. This article reviews them in detail and attempts to provide new insight into the use of dough rheological models.

Abstract A crucial property for the evaluation of bioinks, besides biocompatibility, is printability, which determined by resolution and shape fidelity. Recently, fiber reinforcement was used to overcome rheological limitations introduce biomimetic structuring. This study provides a systematic approach evaluate printability reinforced hydrogels. Alginate Pluronic hydrogels were blended with cel...

In the present study; the glutinous Niaw Sanpatong (NSP) and Niaw Koko-6 (NKK), and the non-glutinous Jasmine (JM) and Saohai (SH) were chemically modified. The difference of these rice varieties on the physicochemical characteristics of the modified rice powders and the properties of the derived gels were evaluated. X-ray diffractometer was used for crystalline structure investigation of the r...

The nonbiodegradable and nonrenewable nature of plastic packaging has led to a renewed interest in packaging materials based on bio-nanocomposites (biopolymer matrix reinforced with nanoparticles such as layered silicates). One of the reasons for unique properties of bio-nanocomposites is the difference in physics at nanoscale as compared to that at macroscale. Therefore, the effect of nanoscal...

The objective of this research is to establish structure-property relationships for macromolecules bearing reversibly associating side-groups. In previous studies we demonstrated shape-memory behavior for elastomer networks bearing strong ureidopyrimidinone (UPy) hydrogen-bonding side-groups. However, relationships between the underlying viscoelastic behavior and side-group features such as hyd...
