One of these reasons is the bacterial superinfection. For this reason, this scoping review attamt to evaluate the significant conterbution of bacterial super-infection on the mortality among hospitalized COVID-19 patients and also to determine the true revalence of bacterial super-infections in that population. Accordingly, a systematic search was employed with precise criteria on the MEDLINE, SCOPUS, PUBMED, and GOOGLE SCHOLAR databases published in the English language in the period of three years from January 2020 to January 2023. The Prevalence of bacterial super-infection (BSI) among COVID-19 patients constitutes a point of contention among publications. this heterogeneity among publications came from the semantic dilemma of co-infection and super-infection. co-infection was determined to be found in a relatively narrow range (1.2-3.1%) while, Prevalence of bacterial super-infection among COVID-19 patients varied from 18.2 to 50%. The bacterial super-infection appears to significantly increase COVID-19 mortality, with the Odd ratio ranging from 1.76 to 10.53 [CI 95%]. Bacterial super-infection among hospitalized COVID-19 patients represents a non-recognized threat, especially during the first wave of the pandemic. The Prevalence of bacterial super-infection is comparable with those observed in previous influenza and SARS epidemics.

Graphene was incorporated into pure ZnO NWs through a cost-effective Hydrothermal Process to act as an electrical charge carrier. J-V curve of prepared nanocomposite was recorded with a light intensity of 100 mW.cm-2. The created nanocomposites were thoroughly investigated by using different electrical and structural characterization techniques such as SEM, XRD, and J-V characteristics. According to SEM examination, the ZnO NWs/graphene composite-based electrode has more porosity than the electrode made using pure ZnO NWs, which will increase the surface area and the amount of dye that can be absorbed. From the graphene advantages the reduced internal resistance and electron recombination loss, these properties allow electrons to transfer to the collection electrode efficiently. Based on these benefits, the ZnO NWs/Graphene nanocomposite photoanode with thickness of 965.11 nm that was used in the DSSC2 was demonstrated a Jsc of 19.50 mA.cm-2 and conversion efficiency of 9.829053%, which opposite to the result of the DSSC1 without graphene.

In dependence of the feedback strength and delay-time we analyze complex bifurcation scenarios for the intensity of the emitted light as well as time series, fast Fourier translate (FFT) and phase plane of all dynamic variables in order to elucidate the dynamics of the light emitting diode. The chaotic dynamic is completely determined by both the variation of the OEFB strength and delay-time of the QD-LED, as evidenced by bifurcation diagram. Our results show that small delay time lead to repeat periodicity of the light emitting towards OEFB. Furthermore, we study chaos synchronization of two QD-LED which are coupled via a unidirectional and bidirectional coupling system. When periodic systems are non-identical, both unidirectional and bidirectional systems depending on the coupling strength parameter the system exhibits completely synchronization.
