Electroerosion Dispersion

One of the most promising methods of processing of practically any conductive material, characterized by relatively low energy costs and environmental cleanliness of the process, is the method of electroerosion dispersion. However, to obtain the electro erosion dispersing of nanoparticles it is necessary to conduct a comprehensive theoretical and experimental research. The article describes the technology of production electroerosion copper nanoparticles from the waste electrical copper wire.

Aim. To obtain conglomerates from copper nanoparticles by the method of electroerosive dispersion in various liquid media (in 1% starch solution, ethanol, acetone, kerosene, petroleum ether) at two different temperatures (negative and room). Assessment of the influence of this factor on the size and shape of the resulting conglomerates. Methods. Methods based on visual observation of the obtained particles using a digital microscope at a magnification of 600x. Results. The results are presented in the form of micrographs of the obtained particles. Conclusions. Conclusions are drawn on the study of the influence of the temperature factor on the morphology (size, shape and ordering) of the resulting conglomerates.

LoRaWAN is a new technology that has been consolidating as a key data communication component to send data in IoT-based systems, due to its ability to send data over long distances with low energy costs. However, literature considers only wireless aspects, disregarding its computational aspects and its integration with IoT platforms, as well as ignoring the deployment possibilities that involve cloud and fog computing. In order to understand the computational impacts of the LoRa architecture we performed a careful performance evaluation study in a complex IoT scenario, exploring cloud and fog computing scenarios and integrating with the IoT FIWARE platform. The results show that the LoRaWAN architecture is scalable, but it has impacts on system performance.

Control of Aedes aegypti mosquito population still leaves problem that needs to be addressed. Theuse of copper wire as an alternative of  larvicide has been studied yet it has not shown asatisfactory result. This is study pure experimental research using research design post test only control group designwith larvae of Aedes aegypti third instar as samples. Methods of data analysis were descriptiveanalysis and analytical analysis.Experiment result shows that based on the success criteria for effective control and safe for health,this research has not found an effective dose of copper wire to kill larvae of Aedes aegyptimosquito that is safe for health for the percentage of larval mortality with concentration of 38.7%Cu was still below 2 ppm.It is recommended that governments and communities use and promote copper wire as analternative larvicide for vector eradication of dengue with predetermined limit of use that is safe forhealth. Further research can be also carried out with media source of water and variety of concentration.
