Published: June 2021

In Ukraine, a three-stage coal combustion system fueled by a natural gas as a reburning fuel for nitrogen oxides emission reduction was mounted on Unit № 4 of the Ladyzhyn TPP. This system was developed in cooperation with Combustion Engineering (USA), VTI (Russia) and the Gas Institute of the National Academy of Sciences of Ukraine and was assembled by the Ladyzhyn TPP staff in 1992. The test runs of this system had confirmed the effectiveness of this method of reducing emissions of nitrogen oxides into the atmosphere (up to 50%).Unfortunately, due to the high price of natural gas and the introduction of limits on its use, currently the use of natural gas as a fuel for reburning is impossible. One of the possible ways to reduce emissions of nitrogen oxides from the coal-fired boiler TPP 312 is the operation of Reburning technology with the biomass pyrolysis product as reburning fuel.
The aim of the work was to evaluate the possibility of the application the biomass pyrolysis products as a reburning fuel in Reburning technology to reduce nitrogen oxides from the coal-fired boiler TPP 312. For this purpose, a detailed computer model of a standard TPP 312 boiler and a TPP 312 boiler with a coal reburning combustion system was developed and built.
The study of the operation the Reburning coal combustion system, which is mounted on the unit №4 DTEK Ladyzhynska TPP, on the design parameters of the operation for the boiler load of 280 MWe was carried out. It was determinate that the supply of reburning fuel at 12% of the total heat capacity of the boiler gives a good level of the reduction of nitrogen oxides (up to 25%), provides no slag conditions for superheater pipes and does not lead to increase of the fuel losses with unburnt carbon.

Published: June 2021

In recent years, there has been a trend of transition from gas to electric heating, due to changes in the energy sector of the economy. Mass use of portable electric heaters allows to reduce fuel consumption by 25%, significantly reduce heat loss and negative impact on the environment. Electric heating is characterized by affordability, high efficiency, low costs of installation and maintenance, the ability to use preferential tariffs.
The purpose of the article is to analyze the technical and economic characteristics and efficiency of typical household electric heaters. The article contains an experimental study of the heat flux and heat of radiation of selected structures. The heat flux density was determined by the calculation method and in comparison with experimental data. Complex heat transfer is taken into account by calculating the heat transfer coefficient. Numerical and experimental study of the natural flow of convection in combination with radiation is carried out with each heated device in the laboratory.
A comparative analysis of the ratio of thermal characteristics to the cost and efficiency of devices. With the help of the author's method of "centers of mass" the comparison of qualitative characteristics of devices is carried out. As a result of the analysis it was established that the ALMAZ TERM Panel does not meet the set quality conditions, which requires further refinement of the design and technological indicators.
Studies show that it is possible to increase the efficiency of heating devices by increasing the consistency of the temperature profile, changing the radiation factor, optimizing the heat transfer surface of the device, as well as by integrating heat storages to store and improve heat distribution. In this case, the electrical energy is converted into heat and stored with subsequent use during peak hours.

Digital technologies have become essential tools in today’s society in many ways. However, not all of them have undergone formal training or assistance to be competent for them to survive in a challenging environment in a digital world. Hence, this study is intended to determine the digital behavior of students in rural schools, including learning how youth self-evaluate their perceptions of digital technologies, digital competencies, and attitudes towards digital technologies. A descriptive quantitative methodology was employed, using survey questions were distributed to selected secondary schools in rural areas. Based on the descriptive analyses of 211 responses, the findings indicate there is a high level of attitude toward ICT usage. Troubleshooting, staying safe online, and being credible; as well as in the ethical knowledge, were found moderately competent. Digital security attributes were at a moderate level; however, privacy concerns have reached a high level of agreement. Perception of ethical digital behaviour was significantly associated with the frequency of ethical digital behaviour of the school students. Specific concerns and emphasis on youth digital technology usage and education must be imposed on ensuring that they are not neglected, and vulnerable to cybercrime, but also on fostering a responsible e-society with excellent digital citizenship attributes.

This study aims to examine two types of performance appraisal systems used to assess food operators to maintain high employee job satisfaction. About 250 questionnaires were distributed around Kampung Bharu area in Kuala Lumpur. The number of questionnaires returned were 210 but only 205 questionnaires were usable for the present study. SPSS was used to analyse the data to test the hypotheses. There were four variables researched in this study, namely Behaviour-Based Performance Appraisal System, Competency-Based Performance Appraisal System, appraiser, and job satisfaction. There was a direct and significant relationship between both appraisal systems with the appraiser (H1 and H2) and employee job satisfaction (H4 and H5) respectively. There was also a direct and significant relationship between the appraiser and restaurant employees’ job satisfaction (H3). The role ofthe appraiser was identified as a mediator in the relationship between Competency-Based Performance Appraisal System and employee job satisfaction (H7). However, the role of the appraiser partially mediated the relationship between Behaviour-Based Performance Appraisal System and employee job satisfaction (H6). The appraiser was regarded as critical in ensuring that the appraisal system adopted be carried out fairly, professionally, and rationally with adequate knowledge to boost job satisfaction among food operator employees in Kuala Lumpur.

In the context of Malaysia, the most common types of cyber attacks are denial of service, intrusion attempts, spam, vulnerability report, fraud, malicious code, and content-related attacks as reported by Cyber Security Malaysia. However, since 2011, cyber attacks such as intrusion attempts, denial of service and spam are decreasing steadily as a result of security measures that have been taken by companies or internet users. Nevertheless, cyber attacks which are steadily increasing are cyber harassment, intrusion and fraud. Approximately 5,328 fraud incidences were reported in 2011 while in 2020, the number of cases rose to 7,593 cases. Out of these cyber attacks in Malaysia, the most proliferating ones have been identified as fraud incidences. Thus, it is highly needed to come up with and propose the best fraud risk management strategy to handle fraud incidences among internet users and internet providers through the utilization of business intelligence tools, and quality enhancement via quality systems in place, quality information, and quality users. With these tools in hand, it is hoped that the proposed model will serve as a framework to mitigate and/or prevent the occurrence of fraud incidences.

Published: June 2021

Magnesium-zinc-sulfophosphate glasses with various concentration of Silver nanoparticles (AgNPs) of molar composition 63.5P2O5–20MgO –15ZnSO4–1.5Eu2O3 –yAgNps (y = 0.0, 0.1, 0.3, 0.5, 0.7,0.9 and 1.1 g in excess) were prepared via melt-quenching method. As-synthesized glasses were characterized at room temperature to determine the relationship between structural and mechanical properties. Densities of glasses were increased from 3.0720 to 4.3304 g.cm-3 with increase in AgNPs embedding levels, suggesting the network shrinkages and enhanced compactness. The Young’s, shear and bulk modulus of glasses were observed to enhance with the increase in AgNPs contents. The Poisson’s ratio of the studied glasses was increased from (0.0978 to 0.1416) while the values of both Vickers hardness (from 0.0658 to 0. 0.0682 GPa) as well as (from 0.8350 to 0.8916) were increased. The proposed glass composition may be useful for the development of hard surface engineering.

Authors: Eltwati Ahmed , Alaa A. A. Elkaseh  
Published: June 2021

In recent decades, escalating traffic volumes initiate asphalt pavements revealed to larger stresses, which can create premature distresses. To enhance the resistance to distresses, modification of the asphalt mixtures has been studied extensively. The objective of this paper is to evaluate the performance of asphalt pavement made with various bitumen types and also different thicknesses. The bitumen types used were conventional asphalt (Ac 60-70) and polymer modified asphalt (PG 76-22). The thickness of asphalt samples tested was 70, 80, and 90 mm. In this study, Accelerated Pavement Testing (APT) was conducted to evaluate the rut depth in the surface of the pavement. The experiment was run up to 20,000 cycles. The results revealed polymer has a significant effect on pavement resistance to rutting. The resistance can be increased by up to 30%. In addition, the rutting occurred rapidly for the first 3,000 cycles. Beyond 3,000, the deformation is increased slowly. On the other side, the results showed that as the HMA thickness increases as the resistance to deformation increases. We, therefore, can conclude that adding particles of polymer to HMA could improve the structural performance of pavement i.e. rutting resistance and reduce the thickness of the surface
