The emergency and notification warning system has the task to, in accordance with legal regulations, rules and observances, perform all necessary measures in order to monitoring, inform, and if necessary, partial or general public alerting of the population in the endangered area. The emergency and notification warning system, which is, among other things, very important for the Emergency management sector of the Republic Serbia, is managed from the command-control center. The importance of this system is evidenced by the fact that it has data transmission on two transmission paths (WiFi and UHF). Based on the above, it follows that it is very important to ensure robust, reliable and uninterrupted operation of the CCC and thus the smooth operation of the emergency and notification warning system. Uninterruptible power supply (UPS) plays a significant role in ensuring reliable, uninterrupted and autonomous operation of the entire system. The role of BPN is very important, because in case of loss of mains power 230 V, 50 Hz, it should take over the power supply of the system. The control system should provide a very fast switching (switching time ≤10 ms) to the backup power supply without interruption and voltage failure of the entire system. When working on a battery bank, the autonomy of the designed system in the absence of mains power is 48 hours. The paper will present the practical implementation of such a system, as well as the experimental results obtained during the operational commissioning of the UPS system. The solution is in use in the CCC-Valjevo of the emergency and notification warning system, starting from June 30, 2020.

The Impact

Abstract Technical challenges associated with telomere length (TL) measurements have prompted concerns regarding their utility as a biomarker of aging. Several factors influence TL assessment via qPCR, the most common measurement method in epidemiological studies, including storage conditions and DNA extraction method. Here, we tested the impact of power supply during the qPCR assay. Momentary fluctuations in power can affect the functioning of high-performance electronics, including real-time thermocyclers. We investigated if mitigating these fluctuations by using an uninterruptible power supply (UPS) influenced TL assessment via qPCR. Samples run with a UPS had significantly lower standard deviation (p < 0.001) and coefficient of variation (p < 0.001) across technical replicates than those run without a UPS. UPS usage also improved exponential amplification efficiency at the replicate, sample, and plate levels. Together these improvements translated to increased performance across metrics of external validity including correlation with age, within-person correlation across tissues, and correlation between parents and offspring.
