This paper exam.nes the transport analysis, including both heat transfer and m.ss transfer, in hybrid nanofluid flow containing gyrotactic m.croorganism. towards a curved oscillatory surface. The influence of m.gnetic fields is also inspected in term. of their physical characteristics. To depict the phenom.na of transport, m.dified versions of both Fick's and Fourier's laws are used. Additionally, the characteristics of both heterogeneous and hom.geneous chem.cal reactions are also incorporated. Utilizing a curvilinear coordinate system. the flow problem.is form.lated as partial differential equations(PDEs)for m.m.ntum. concentration, m.croorganism.field, and energy. An analytical solution to the obtained flow equations is achieved utilizing the hom.topy analysis m.thod(ham).The effects of significant flow param.ters on the pressure and m.croorganism.fields, velocity, oscillation velocity, concentration, and tem.erature distributions are shown via graphs. Furtherm.re, the variations in skin friction, m.ss transfer rate, heat transfer rate, and local m.tile num.er due to different involved param.ters are presented in tables and are analyzed in detail. Graphical results indicate that the curves of velocity and tem.erature fields are enhanced as the values of the solid volum. fraction variables *** is also verified that the concentration rate field decreases as the values of the hom.geneous reaction strength param.ter and the radius of curvature param.ter increase, and it increases with the Schm.dt num.er and the heterogeneous reaction strength *** outcom.s show a favorable response of the m.tile num.er to advanced values of the Peclet num.er, the Schm.dt num.er, the m.croorganism.difference param.ter, and the bio-convective Lewis num.er.

This study focus on developing new salinity tolerance and high yielding rice lines, using m.rkers assisted backrossing (m.BC). Total of 500 SSR m.rkers on 12 rice chrom.som.s were screened for parental polym.rphic m.rkers. Of which, 52 prim.rs in the Saltol region were checked with the two parents varieties to identify polym.rphic prim.rs for screening the Saltol region of the breeding populations. For each backcross generation of ASS996/FL478, approx. 500 plants were screened with 63 polym.rphic m.rkers distributed on 12 chrom.som.s. The two BC1F1 plants P284 and P307 which had the highest recipient alleles up to 89.06% and 86.36%, were chosen for the next backcrossing. Three BC2F1 plants with the recipient alleles up to 94.03% and 93.18% were used to develop BC3F1 generation. The best BC3F1 plant was P284-112-209 with all the recipient alleles and Saltol region. The four plants P307-305-21, P284-112-195, P284-112-198, P284-112-213 were the second ranking with only one loci heterozygous (applied 63 m.rkers covered on 12 chrom.som.s). These five plants were chosen as the breeding lines for result of Saltol-AS996 introgression. The breeding line BC4F1 having 100% genetic background of donor variety is ready for develop new salinity tolerant variety ASS996-Saltol to cope with clim.te change.

Various redox-active organic m.lecules can serve as ideal electrode m.terials to realize sustainable energy storage system.. Yet, to be m.re appropriate for practical use, considerable architectural engineering of an ultrathick, high-loaded organic electrode with reliable electrochem.cal perform.nce is of crucial im.ortance. Here, by utilizing the synergetic effect of the non-covalent functionalization of highly conductive non-oxidized graphene flakes (NOGFs) and introduction of m.chanically robust cellulose nanofiber (CNF)-interm.ngled structure, a very thick (≈ 1 m.), freestanding organic nanohybrid electrode which ensures the superiority in cycle stability and areal capacity is reported. The well-developed ion/electron pathways throughout the entire thickness and the enhanced kinetics of electrochem.cal reactions in the ultrathick 5,10-dihydro-5,10-dim.thylphenazine/NOGF/CNF (Dm.Z-NC) cathodes lead to the high areal energy of 9.4 m.h·cm.2 (= 864 Wh·kg−1 at 158 W·kg−1). This novel ultrathick electrode architecture provides a general platform.for the developm.nt of the high-perform.nce organic battery electrodes.

We em.loy the hom.topy analysis m.thod （ham） to obtain approxim.te analytical solutions to the heat-like and wave-like equations. The ham contains the auxiliary param.ter h, which provides a convenient way of controlling the convergence region of series solutions. The analysis is accom.anied by several linear and nonlinear heat-like and wave-like equations with initial boundary value problem.. The results obtained prove that ham is very effective and sim.le with less error than the Adom.an decom.osition m.thod and the variational iteration m.thod.

In this paper, iterative or successive approxim.tion m.thods for the hamilton-Jacobi-Bellm.n-lsaacs equations （HJBIEs） arising in both determ.nistic and stochastic optim.l control for affine nonlinear system. are developed. Convergence of the m.thods are established under fairly m.ld assum.tions, and exam.les are solved to dem.nstrate the effectiveness of the m.thods. However, the results presented in the paper are prelim.nary, and do not yet im.ly in anyway that the solutions com.uted will be stabilizing. m.re im.rovem.nts and experim.ntation will be required before a satisfactory algorithm.is developed.
