Abstract Spectral analysis characterises oscillatory time series behaviours such as cycles, but accurate estimation requires reasonable numbers of observations.At the time of writing, COVID-19 time series for many countries are short: pre- and post-lockdown series are shorter still.Accurate estimation of potentially interesting cycles seems beyond
An iteration sequence based on the BLUES (beyond linear use of equation superposition) function method is presented for calculating analytic approximants to solutions of nonlinear partial differential equations.This extends previous work using this method for nonlinear ordinary differential equations with an external source term.Now, the initial co
Shrimp culture is one of the most lucrative and fast growing sectors in marine aquaculture; however, the intensification of cultures to meet the growing demands has incremented the incidence of bosch 4100 table saw motor replacement diseases, causing substantial economic losses.Disease outbreak prevention and control is mostly based on antimicrobia
Abstract In the present study, a series of 2-(4-(2-chloroacetyl)piperazin-1-yl)-N-(2-(4-chlorophenyl)-4-oxoquinazolin-3(4H)-yl)acetamide derivatives was synthesized and its chemical structures were confirmed by physicochemical and spectral characteristics.The synthesized compounds were evaluated for their in vitro antimicrobial (tube dilution techn
