This paper presents a proposal of a thermal instrument intended for the evaluation of heat energy of fluid fuels. Two thermal devices the flowmeter and the combustor are the basic components of the instrument. The meter maintains a constant temperature in the vicinity of the combustion zone. The amount of heat energy in the fuel is calculated as the ratio of the electric power change expressed in Watts to the change of fuel supply delivered to the combustor within a time period of 1sek. The method enables a direct evaluation of fuel energy expressed in Jules per unit of mass or volume. For some applications, the meter may be a good alternative for a bulky bomb calorimeter.

In Memoriam

Abstract In Memoriam—In memory of Dr. Zbigniew Magonski, a talented electronic engineer and inventor, was born in Glubczyce, Poland in 1950 and passed away in Cracow, Poland in 2017. He received M.Sc. degree in Solid State Technology from the Technical University of Wrocław, Poland in 1973, and PhD degree from the AGH University of Science and Technology, Cracow, Poland in 2000. For 15 years, he was with the R&D Center for Hybrid Microelectronics, Cracow Poland. At that time, his interest was focused on hybrid A/D, D/A converters also on DC HV power converters. Later, for 28 years, he was with the Department of Electronics, AGH University of Science and Technology, Cracow, Poland. His research interests covered ceramic microfluidic systems, hydrocarbon combustors, and high-temperature solid oxide fuel cells. In 1994–1995, he was with Summit Technology, Massachusetts, involved in a project relating to HV supplying of excimer lasers. He was a member of IMAPS US Chapter, the author of 13 patents and almost 50 technical papers connected with electronic technology. He was a caring husband and father and a good friend of many of us. We will miss you, Zbyszek. This article presents a proposal of a thermal instrument intended for the evaluation of heat energy of fluid fuels. Two thermal devices the flow meter and the combustor are the basic components of the instrument. The meter maintains a constant temperature in the vicinity of the combustion zone. The amount of heat energy in the fuel is calculated as the ratio of the electric power change expressed in Watts to the change of fuel supply delivered to the combustor within a time period of 1 s. The method enables a direct evaluation of fuel energy expressed in Joules per unit of mass or volume. For some applications, the meter may be a good alternative for a bulky bomb calorimeter.

This paper describes influence of time and temperature of heat curing on progress of mechanical characteristics of concrete mixtures based on alkali activated fly-ash (POPbeton). One of the major impacts for the correct treatment of alkaline activation is the quantity of heat energy in a given time period which is supplied during activation. The paper describes the dependence of progress of compressive strength of POPbeton on the time and temperature of heat curing. It was assembled a predictive model which describes the dependence of the supplied heat energy over time on the resulting properties of POPbeton. The result is a tool that can predict the resulting values of mechanical characteristics of test samples of POPbeton.

Silver nanoparticles are used an increased attention for various biomedical and medical applications. In this study, green synthesis of silver nanoparticles was made with simple method by using peroxidase enzyme partially purified fromEuphorbia(Euphorbia amygdaloides) plant. Optimum pH, temperature and time period were determined to obtain silver nanoparticles using the peroxidase enzyme. The result shows that higher silver nanoparticle was synthesized for 4 hours and at 20°C and pH 8. Also, optimal concentration of metal ions was found as 0.5 mM. The synthesized silver nanoparticles were characterized by UV spectrum, scanning electron microscope (SEM) and X-ray diffraction. Antibacterial activity of silver nanoparticles was measured against some microorganisms such asSerratia marcescens, Yersinia pseudotuberculosis, Klebsiella pneumoniae, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Pseudomonas aeruginosa, Salmonella typhimurium, Listeria monocytogenes, and Escherichia coli. Synthesized silver nanoparticles have wide spectrum antibacterial activity in low concentration and may be a good alternative therapeutic approach in medicine and pharmaceutical fields in future.

Overall Efficiency

Solar energy is one of biggest source of energy with high potential due to radiation of sun. The energy generated by solar having many applications in domestic, commercial and industrial application. Sand and dust particles accumulating on solar panel so reducing the power output. Also the panels which are cleaned are efficient to generate electric power. There are some traditional methods available but they are manual. Hence to overcome these problems automatic robot is designed for improving overall efficiency of solar panel. The cleaner was equipped with stepper motor, DC motors and brushes for accurate operation of vertical and horizontal motion. The Dc motors cleans the panel in horizontal direction and stepper motor in vertical direction. The various tests are performed which gives result that overall operation can be completed in particular time period. The robot’s system is controlled by an atmega328 microcontroller. So it is found that these technique to clean the solar panel is better and cheaper than other method.
