Training Modules

The main purpose of this study is to calculate the return on investment of two training modules of electrical protection and uninterruptible power supply (UPS) using the corrective approaches applied to the basic model presented in previous research. In this study, first, the effect points of the training were identified using open questionnaires completed by experts. Then, its content validity is ensured by Lawshe, Waltz, and Basel approaches. Data on training costs were extracted through financial documentation and estimates. Details of measures, savings, internal supply, and so on were identified and cited to convert the observed effects into financial equivalents. Using the analytic hierarchy process (AHP) approach, the role of training in comparison with other initiatives in each of the effects and achievements was determined, and the net financial achievements of the training were determined. The training return on investment for the electrical protection module was 243% and for the UPS module was 1637%.

Main Component

UPS (Uninterruptible Power System) is an energy storage device, and it is also a uninterruptible power supply which contains the inverter as the main component and works at the constant voltage constant frequency. it is playing an increasingly important role. Some suggestions are mainly proposed to ensure the safety of UPS power supply system in this paper, which make the UPS power supply system really play the role of escort in the practical application.

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.
