Measurement of Low Concentration of Nanosized Objects Suspended in a Liquid Medium
2018
The new optical scheme of refractometer with temperature stabilisation 10-2 °C is developed, which allows measuring a refractive index of the sample with accuracy not worse than 10-5; dependence of refraction index on concentration of SiO2 nanoparticles in liquid suspension is obtained within the framework of the research.
Simulations of the structure and rheology of wet webs
2009
In this Thesis we modified a recently introduced model for fiber suspensions to be applicable to wet fiber networks so as to analyze by computer simulations their structural and rheological properties. These properties were compared, under tensile loading in particular, to those of wet and dry paper. The model used operated at the fiber level, where the dynamics of fiber motion were determined by fiber stiffness and fiber-fiber interactions such as friction and adhesive forces. Water surface tension, inter-fiber contact area, and moisture content all contributed to the latter force. The tensile strength of wet fiber networks could be described in terms of a very simple function of adhesion-…
Nuove regole di applicazione del diritto UE in sede nazionale?
2022
Two important judgments of the Consiglio di Stato (Italy) allow revisiting general institutions relating to the primacy of EU law and the instruments that guarantee its application in national law. Among others are the direct effect of the directives, the need for a preliminary ruling, and the so-called double preliminary ruling. Finally, the essay highlights some critical issues regarding the limits of the non-application of the law, the overcoming of the res judicata, and the temporary suspension of the ousting effect of a rule of EU law by national courts.
SOLID-LIQUID SUSPENSIONS IN UNBAFFLED TANKS
2009
Unbaffled stirred tanks are seldom employed in the process industry as they are considered poorer mixers than baffled tanks. However, they might provide significant advantages in a wide range of applications like crystallization processes as well as for food and pharmaceutical industries, where the presence of baffles is often undesirable. In the present work solid-liquid suspension in an unbaffled stirred tank was investigated. A novel experimental method (steady cone radius method) was devised to ease the evaluation of the minimum impeller speed for complete particle suspension (Njs). Experiments encompassed a quite wide range of particle sizes, densities and solids concentration. The Njs…
Układ częściowy obejmujący wierzytelności zabezpieczone rzeczowo a zawieszenie egzekucji z mocy prawa
2018
Niniejsze opracowanie odnosi się do problematyki wpływu otwarcia przyspieszonego postępowania układowego z układem częściowym na postępowanie egzekucyjne dotyczące wierzytelności zabezpieczonej rzeczowo na składnikach majątku dłużnika. Zaprezentowany zostanie pogląd prawny, i jego uzasadnienie, według którego, w przypadku gdy wierzytelność zabezpieczona rzeczowo na majątku dłużnika zostaje objęta układem częściowym wówczas egzekucja co do niej ulega bezwzględnemu zawieszeniu z mocy samego prawa (ipso iure)
Strain hardening in liquid-particle suspensions
2005
The behavior of a liquid-particle suspension induced to sheared motion was analyzed by numerical simulations. When the velocity (strain) of the suspension began to increase, its viscosity first stayed almost constant, but increased then rapidly to a clearly higher level. This increase in viscosity is shown to be related to formation of clusters of suspended particles. Clusters are shown to increase the viscosity by enhanced momentum transfer though clustered particles. This is the mechanism behind the strain-hardening phenomenon observed in small-strain experiments on liquid-particle suspensions.
