We considered figures of merit for chemical and biological sensors based on plasmonic structures and utilizing adsorption/desorption mechanism. The operation of these devices in general is limited by noise determining the minimum detectable refractive-index change. We dedicated our work to the intrinsic noise mechanis…
In this paper, the temperature compensation of aluminum nitride (AlN) Lamb wave resonators using edge-type reflectors is experimentally studied and demonstrated. By adding one compensating silicon dioxide (SiO2) layer with an appropriate thickness, the Lamb wave resonator can achieve a zero linear temperature coeffici…
The ferromagnetic resonance (FMR) spectra of magnetite nanoparticles in aqueous solutions and solid polymer films were analyzed at different particle concentrations, matrix rigidities, temperatures, external magnetic effects, and positions of flat samples in the field of the spectrometer. The formation of linear aggre…
Improper post-harvest handling and storage under room temperature lead to high loss of moisture resulting in loss of strength and development of flaccidity in okra tissues, apart from the loss of its characteristic green color. In this study, different weights of freshly harvested okra pods (Hibiscus esculentus L.) we…
Experimental and theoretical studies of the electron-impact excitation of the $(4s4p)\text{ }{^{1,3}P}_{1}$, $(4s5s)\text{ }{^{3}S}_{1}$, and $(4s4d)\text{ }^{1,3}D$ states of zinc atoms are reported. Relative emission cross sections were measured from the excitation thresholds to 50 eV incident energy. Theoretical an…
The extractability of heavy metals with exchangeable bases is of particular importance for two reasons: (i) Ca, Mg, K, and Na form the predominant electropositive elements in the soil solution (on molar basis) and can interact with adsorbed fractions of heavy metals; and (ii) single extractions aimed at ascertaining s…
Influence of the slot opening width and rotor pole radius on the cogging torque and total torque developed by a three-phase permanent magnet synchronous motor (PMSM) is investigated. The number of motor poles and number of stator slots are fixed. Finite element technique is used for the computation of machine characte…
We report on experimental observations of self-assemblies in colloidal dispersions of clay nanoplatelets and magnetic nanoparticles. Visual observations have been combined with small angle X-ray scattering (SAXS) in the study of several composites at a fixed clay concentration in the dilute regime, and varying ferrofl…
The structure of a cellulose-decomposing bacterial association was described using phenotypic and phylogenetic characteristics. Based on their morphological, physiological, and biochemical characteristics, the bacteria isolated from the association were identified as Sporocytophaga sp., Xanthomonas sp, and Pseudomonas…
The possibility of controlling the surface energy and wettability of polyvinyl chloride and polyethylene films by chemical gas-phase modification was studied. The surface of the initial and chemically modified polymeric materials was examined by atomic force microscopy.
Kaolinite transformation into other kaolin layer polytypes under pressure is of interest in many materials or industrial applications as well as in seismology. Assuming that this transformation would involve a layer slipping mechanism similar to that of the reversible dickite to HP dickite transformation observed at 2…
Laser Induced Periodic Surface Structures (LIPSS) were obtained on ZnO thin films deposited on sapphire substrate.The structures were creaded by scanning the sample surface with a focalised femtosecond laser beam in air.The period and depth of the structures were measured by Atomic Force Microscopy (AFM) and Scanning…
Surface tensions of high‐salinity solutions are significantly different from those of pure water. Our objective was to develop and test a methodology to determine whether these surface tension effects predictably alter imbibition into dry and moist porous media. Static and dynamic experiments were performed using four…
We present, in a unifying way, the main components of three asynchronous event-driven algorithms for simulating physical systems of interacting particles. The first example, hard-particle molecular dynamics, is well known. We also present a recently developed diffusion kinetic Monte Carlo algorithm, as well as a novel…
Abstract An 21 heimischen und 11 überseeischen Holzarten wurde die Gleichgewichtsfeuchte bei 20 °C und 35, 50, 65, 80 und 95 % relativer Luftfeuchtigkeit experimentell in der Adsorptionsphase bestimmt. Aufbauend auf den experimentell bestimmten Mittelwerten wurden mit dem Hailwood‐Horrobin‐Modell (HH‐Modell) ausgewähl…
The aim of the present study was to identify deletion/insertion polymorphism of the bovine prion protein (PRNP) gene within the promoter sequence (23 bp indel), intron 1 (12 bp indel) and the 3' end untranslated region (14 bp indel). The experiment was performed on three groups of animals protected under a genetic res…
This paper presents results of an experimental study of electrohydrodynamic disturbances during initiation of the predischarge stage in transformer oil under positive lightning impulse.
One-dimensional Si nanostructures, grown on a Ag(110) substrate, have been used as a template to grow Co nanolines. Before Co deposition, the self-assembled Si nanostripes were characterized by high-resolution scanning tunneling microscopy. From this, an original atomic arrangement of silicon adatoms forming nanostrip…

Artificial neural networks are an efficient tool for modelling production control processes using data from the actual production as well as simulated or design of experiments data. In this study two artificial neural networks were combined with the control process charts and it was checked whether the data obtained b…
