setting time and rheological properties, is ambiguous [4, 7].
The results of the research [8] indicate a reduction of the yield stress and plastic viscosity with the increase in limestone content in cement, while the results of studies [9] indicate the opposite relationships. Authors of works [3, 10] showed a decrease in the yield stress and an increase of plastic viscosity with an increase in the limestone content. The results of tests are usually only related to the chemical and physical properties

Figure 6 describes the changes in viscosity of the mixture of pullulan and aloe vera with respect to stress. The figure shows that the viscosity is decreasing with increasing the stress. Such viscosity decrease is directly related

. Moreover, bacterial cross-feeding interactions in which fermentation of prebiotics is involved is poorly characterized. Here, we report the exploration of new candidates for the syntrophic bacterial interactions and fermentability of oat non-starch polysaccharides (NSP). The results obtained by differentiating composition, viscosity and concentration of oats NSP in fermentation medium showed that Bacillus licheniformis pre-digests oat NSP, degrades high viscosity of oat β-glucan and makes hemicellulose

effectiveness of antifoaming agent by increasing the force needed to overcome the interfacial membrane;
–shear forces – they have significant effects on the defoamer operation. High shear forces reduce the size of the perspiration drops, which become too small to break up the wall of the air bubble so that it is less effective. In addition, shear forces cause intense foam formation;
–viscosity – the viscosity of a defoamer affects the ease of its dispensing and dispersion in the desired medium [31].

conjunction with the novel SMS. Method: A composite calcium sulphate and calcium phosphate bone graft substitute was examined. The effects of powder particle size, and the powder-to-liquid ratio on the injectability of the iBGS through the SMS were investigated. The viscosity, injectability, and mechanical properties of the new composite mixtures were assessed using rheology and universal compression measurements. Results: The results showed that the optimised injectable formulation of the bone cement was

Introduction
A blood-mimicking fluid (BMF) is made up of ultrasound scattering particles that stay neutrally buoyant in a fluid. For these particles to be able to remain suspended in the fluid, their density must be very close or equal to the density of the mixture fluid. In addition, the BMF must also have acoustic properties (speed of sound, attenuation and backscatter power) and physical properties (density and viscosity) that are close to the internationally acceptable standard(1–3). The

bacteria during formation of the casein curd of milk are capable of water retention and thereby inhibit syneresis in fermented drinks. In addition, by reacting with proteins, they may contribute to the reinforcement of the casein network, which improves the rheological properties, quality of the final product, and cheese yield. The use of adjunct EPS(+) starter cultures improves the smoothness, viscosity and stability of a yoghurt gel and of other fermented milks [4, 22, 32]. The character of changes
