Continuum mechanics predicts that the propagation speed of non-equilibrium information in solids is limited by the longitudinal wave speed, so is crack propagation. However, solids are essentially discrete systems. In this paper, via theoretical analysis and numerical simulations, it is demonstrated in a straightforward way that nonequilibrium disturbance (e.g. force, displacement, energy, and ...

Using the persistent current I induced by an Aharonov-Bohm flux in square lattices with random potentials, we study the interplay between electronic correlations and disorder upon the ground state (GS) of a few polarized electrons (spinless fermions) with Coulomb repulsion. K being the total momentum, we show that I ∝ K in the continuum limit. We use this relation to distinguish between the con...

Tailings ponds Slovinky and Markušovce (Slovakia) belong to the group of high-risk areas threatening human health environment due high concentrations potentially toxic elements. The aim this study was identify iron bacteria living in these extreme environments assess impact selected physicochemical parameters drainage water, flowing from tailings ponds, on dynamics their population.The material...

The aim of this study was to assess the influence atmospheric air temperature on efficiency and reliability pollutants removal from wastewater. studied facility a hybrid constructed wetland wastewater treatment plant with vertical horizontal flow serving single-family building in village Krajanów south-western Poland. operation evaluated basis studies conducted 2021–2022. tests included physico...

Robust statistical tools were applied on the water quality datasets with the aim of determining the most significance parameters and their contribution towards temporal water quality variation. Surface water samples were collected from four different sampling points during dry and wet seasons and analyzed for their physicochemical constituents. Discriminant analysis (DA) provided better results...

Considerable research is focused on understanding the functionality of starch hydrolysis products (SHP) consisting of glucose, maltose, maltooligosaccharides (MOS), and maltopolysaccharides (MPS). A confounding factor in this research is the high molecular dispersity of commercially available SHP. The study presented herein characterizes a flexible fractionation approach for lowering the disper...
