this paper a novel homotopy perturbation method has been presented for forced convection boundary layer problems in a porous medium. Noting the infinite condition, a homotopy form which is similar to the singular perturbation form has been considered. The inner and outer solutions have been achieved and the coincidence of the results has been investigated with a proper matching method. The resu...

Abstract This paper reviews application of the Daily Egg Production Method (DEPM) to sardine (Sardinops sagax) off southern Australia between 1995 and 2019. Coefficients variation (CVs) estimates spawning biomass (SB) were reduced from 23–59% 8–12% by: (i) estimating mean daily egg production (P0), fraction (S), sex ratio (R) all historical data rather than annually; (ii) combining batch fecund...
