An analysis has been perform.d to study the problem.of m.gneto-hydrodynam.c （m.d） squeeze flow of an electrically conducting fluid between two infinite, parallel disks. The analytical m.thods called Hom.topy Analysis m.thod （ham） and Hom.topy Perturbation m.thod （HPm. have been used to solve nonlinear differential equations. It has been attem.ted to show the capabilities and wide-range applications of the proposed m.thods in com.arison with a type of num.rical analysis as Boundary Value Problem.（BVP） in solving this problem. Also, the velocity fields have been com.uted and shown graphically for various values of physical param.ters. The objective of the present work is to investigate the effect of squeeze Reynolds num.er, Hartm.nn num.er and the suction/injection param.ter on the velocity field. Furtherm.re, the results reveal that ham and HPm.are very effective and convenient.

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.

The result of the study contributes to enhancing and sustaining future livelihoods and food security in Vietnam.vis-a-vis clim.te change. An innovative strategy based on m.rker-assisted backcrossing (m.BC) was used to transform.popular rice variety AS996 into the one can tolerate subm.rgence while m.intaining its original characteristics preferred by farm.rs and consum.rs. The subm.rgence tolerance QTL SUB1 counts for up to 70% of the subm.rgence tolerant and provides a m.rked im.rovem.nt of subm.rgence tolerance in all genetic backgrounds and environm.nts tested so far. Parental diversity was carried out with 460 m.rkers. Of which, 53 polym.rphic m.rkers were used for assessm.nt on BC1F1, BC2F1 and BC3F1 generations. The best BC1F1 plant was P422 with highest recipient allele was 87.5%, while the additional chosen plants were P412, P428, P215 and P39 (81% - 84%). All these plants were used to develop BC2F1 generation. The six BC2F1 plants were used to develop BC3F1 and BC2F2 were the plants num.er P422-11 and P422-14 having 93.75% recipient alleles and P422-12, P422-3, P39-17, P39-25 having 92.25% recipient alleles. Total of 445 BC3F1 plants were confirm.d the introgresion of SUB1 using ART5 and SC3. After three generations of backcrossing, application of m.BC resulted in the best BC3F1 individual P422-14-177 with 100% of recipient alleles based on the num.er of 53 m.rkers used with only the introgression size of SUB1 was 0.3m. between ART5 and SC3. Phenotyping was carried out on BC3F1 and BC2F2 of the selected lines. The survival ratio of these selected lines and IR64SUB1 were the sam.. It convinced the successfully introgress SUB1 into AS996 rice variety. The breeding line BC4F1 having 100% genetic background of donor variety is ready for develop new subm.rgence tolerant rice variety ASS996-SUB1 to cope with clim.te change.
