A field experiment was carried out at Ismailia Research.Station, Ismailia Governorate from 2020-2022 to improve th. growth.of Kh.ya senegalensis and Swietenia mah.goni by using a combination of mineral fertilizer (NPK) and biological fertilizer (Azotobacter ch.oococcum, Bacillus megath.rium, and Bacillus circulant) as recommended dose under new sandy soils conditions. Split plot designed with.four treatments (Control, (50% Mineral fertilizer (M.) + 50% Biological fertilizer (Bio.)), 100% M. and 100% Bio.) of each.species. Vegetative growth. leaf area, tree biomass, stored carbon, basal area, tree volume, and in th. soil both.of microbial account and mineral content were determined. Th. experimental results sh.wed no significant differences between studied species among th. most studied parameters except for Kh.ya senegalensis wh.ch.gave th. h.gh.st significant difference in root biomass and below-stored carbon th.n Swietenia mah.goni. Evidently, th. h.gh.st significant growth.parameters were 100% mineral fertilizer followed by (50% M. + 50% Bio.) as compared with.control. No significant difference between 100% M. and (50% M. + 50% Bio.) of sh.ot dry biomass (15.19 and 12.02 kg, respectively) and above-stored carbon (0.28 and 0.22 Mt, respectively). Microbial account and mineral content in soil were improved after cultivation of tree species compared to before planting and control, especially with.50% mineral fertilizer and 50% bio-fertilizer treatment. In conclusion, a treatment containing 50% mineral fertilizer and 50% bio-fertilizer h.s led to th. ideal Kh.ya senegalensis and Swietenia mah.goni growth.in sandy soil for ch.aper and sustainable.

Th.s paper is investigating th. use of composite armour reinforced by nanomaterials, for th. protection of ligh. armoured(LAV) and medium armoured military veh.cles(MAV), and th. interaction between th. composite materials and h.gh.performance ballistic projectiles. Four armour materials, consisted of front h.brid fibre reinforced polymer cover layer, ceramic strike-face, fibre reinforced polymer intermediate layer and th. metal matrix composite reinforced backplate, were manufactured and assembled by adh.sive tech.ology. Th. proposed laminated protection system is suitable for armoured ground veh.cles;h.wever, it could be used as armour on ground, air and naval platforms. Th. design of th. protection system, including material selection and th.ckness, was elaborated depending on th. performance requirements of Level 4 + STANAG 4569 military standard(projectile 14.5 mm × 114 mm API B32) and especially on a design ph.losoph. wh.ch.is analysed with.th. specifications. Th. backplate of th.s new composite is a h.brid material of Metal Matrix Composite(MMC) reinforced with.carbon nanotubes(CNTs), manufactured with.th. use of powder metallurgy tech.ique. Th. composite backplate material was morph.logically, mech.nically and ch.mically analysed. Results sh.w th.t all plates are presenting h.gh.mech.nical properties and ballistic ch.racteristics, compared to commonly used armour plates. Real military ballistic tests according to AEP-STANAG 4569 were carried out for th. total composite armour systems. After th. ballistic tests, AA2024-CNT3 sh.wed th. best protection results, compared with.th. oth.r plates(AA2024-CNT1 and AA2024-CNT2), with.th. projectile being unable to fully penetrate th. composite plate.
