This paper presents the application of a Self-exited Acoustical System (SAS) for monitoring stress changes in the cement plant. The change in the speed of wave propagation, which is associated with a change in the resonance frequency in the system is caus... see more

Hard gold and silver are applied in coating owing to their high hardness, good wear and corrosion resistance for engineering application (e.g. on generators slip rings, sliding contacts and small machine parts) and are typically plated on copper (mostly),... see more

Nowadays the maintenance of long welded rails track is an urgent problem of railway industry. The inexact diagnostic method of the stressed state of long welded rails is used now on railways of Ukraine. This method does not give a direct and true picture ... see more

AbstractFluorescence analysis has become a powerful and widely used technique among plant physiologists and ecophysiologists because its measurement bears a relationship to photosynthesis. Therefore, chlorophyll fluorescence (CF) measurements have become ... see more

This paper deals with assesing of the influence of climate temperatures on deformations and stresses in a cross section of the Nusle Bridge. The main purpose is to describe the measurement of the thermal fields, to compare measured and computed temperatur... see more

A super pressure balloon (SPB) is an aerostatic balloon that can fly at a constant altitude for an extended period. Japan Aerospace Exploration Agency (JAXA) has been developing a light-weight, high strength balloon made of thin polyethylene films and dia... see more

A wealth of knowledge has been published in the last decade on redox regulations in plants. However, these works remained largely at cellular and organelle levels. Simple indicators of oxidative stress at the plant level are still missing. We developed a ... see more

This study is intended to design a system connected to the Distributed Generation (DG) sourced from solar cells, using Matlab/Simulink. A Phasor Measurement Unit (PMU) is installed in the DG system to monitor the phasor voltage and current. Furthermore, t... see more

This study aimed to evaluate the physiological response of female beef cattle to peatland microclimate stress in Central Kalimantan. This study used direct observation on small holder beef cattle farm.  Microclimate data on 41 units cattle barns and ... see more
