We consider geometrical conditions of liquid crystals of bent-shape molecules that result in optically isotropic antiferroelectric structure that can be reversibly switched to birefringent states. An example of an ester based banana-shape substance is discussed that almost fulfills the ideal conditions and provides fast electro-optical switching with or without crossed polarizers.

Samples of banana were dried in a two-stage heat pump dryer capable of producing stepwise control of the inlet drying air temperature while keeping absolute humidity constant. Two stepwise air temperature profiles were tested. The incremental temperature step change in temperature of the drying air about the mean air temperature of 30 $^{\circ}C$ was 5 $^{\circ}C$. The total drying time for each temperature-time profile was about 300 minutes. The drying kinetics and color change of the products dried under these stepwise variation of the inlet air temperature were measured and compared with constant air temperature drying. The stepwise air temperature variation was found to yield better quality product in terms of color of the dried product. Further, it was found that by employing a step-down temperature profile, it was possible to reduce the drying time to reach the desired moisture content.

This work described some essential factors necessary for micro-propagation of banana for mass production of synthetic seeds for germ plasm conservation, and how peroxides activity of conserved tissue was influenced. Shoot tips of field grown plants were used to obtain shoot clusters on shoot proliferation medium (MS medium supplemented with 5 mg/l BAP). Using longitudinally-split shoot tip technique, 18720, 8640, 7488, 2016 plantlets were obtained from one shoot tip of Maghraby, Grand Naine, Balady, and Williams, respectively, in six subculture, one month each, on solid medium. Shoot tips excised from in vitro grown plantlets were encapsulated in calcium-alginate beads and stored at $4^{\circ}C$ for one month on half-strength MS basal medium without growth regulators or sugars. After one month all the viable-conserved synseeds formed shoots when they were transferred to MS basal medium, some of them showed synchronous formation of shoot and root systems in one week. Plants retrieved from encapsulated shoot tips were hardened off and transferred to soil.

Four banana-shaped compounds have beene synthesized introducing ester linking group into mesogenic unit, varying the central core with 1,6-, 1,7-, 2,3-, and 2,7-naphthylene units, and introducing the dodecyloxy group as the terminal flexible unit. All obtained compounds except one with 1,7-naphthylene unit were reversibly thermotropically liquid crystalline. The compound with 1,7-naphthylene unit could not form the mesophase due to its asymmetrical and sharp substitution angle. The compounds with 1,6- and 2,3-naphthylene units showed an antiferroelectric switchable smectic phase, which has been designated B2 phase. Interestingly, the compound with the 2,3-naphthylene unit showed the two mesophases of B2 and nematic phase.

Banana planting altered microbial communities and induced the enrichment of Fusarium oxysporum in rhizosphere compared with that of forest soil. Diseased plant rhizosphere soil (WR) harbored increased pathogen abundance and showed distinct microbial structures from healthy plant rhizosphere soil (HR). The enriched taxon of Bordetella and key taxon of Chaetomium together with some other taxa showed negative associations with pathogen in HR, indicating their importance in pathogen inhibition. Furthermore, a more stable microbiota was observed in HR than in WR. Taken together, the lower pathogen abundance, specific beneficial microbial taxa and stable microbiota contributed to disease suppression.

Twenty crossbred (Yorkshire ${\times}$ Landrace) gestating sows were used to determine the effects of Moringa Oleifera leaf (MOL) supplementation in lactating sow diets with or without banana peel powder (BPP) on reproductive performance, fecal moisture content, rectal temperature and hormone profile. The treatments were as follows: 1) CON (control diet), 2) M1 (control diet + 0.5% MOL), 3) M2 (control diet + 1.0% MOL), 4) M3 (control diet + 0.75% MOL and 0.75% BPP), and 5) M4 (control diet + 1.5% MOL and 1.5% BPP). The diets was fed from da 107 of gestation to weaning. MOL and BPP supplementation decreased (p < 0.05) the fecal moisture content compared with that of the CON at day 0 and 7 after farrowing, and 1.0% supplementation of MOL also decreased (p < 0.05) the fecal moisture content at day 14 after farrowing. On farrowing day, MOL supplementation decreased (p < 0.05) the blood cortisol and norepinephrine concentrations compared with the CON. In conclusion, the results of this study show that MOL supplementation decreased the fecal moisture content and plasma concentrations of cortisol and norepinephrine, and MOL and BPP supplementation also decreased the fecal moisture content in lactating sows.
