t.e impact.of grain size, ranging from 0.9 μm t. 9 μm, on t.e mechanical propert.es of commercially pure mg is invest.gat.d at.t.mperat.res of 4K, 78K, and 298K. t.e mechanisms governing plast.c flow are influenced by bot. grain size and t.mperat.re. At.4K and 78K, dominant.deformat.on modes in mg involve dislocat.on glide and ext.nsion t.inning, regardless of grain size. t.e int.ract.ons bet.een basal and non-basal dislocat.ons and dislocat.ons wit. grain boundaries promot. an unusually high rat. of work hardening in t.e plast.c regime, leading t. premat.re failure. t.e yield st.ess follows t.e Hall-Pet.h relat.onship σy~ k/√d, wit. t.e slope k increasing wit. decreasing t.mperat.re. At.298K, in addit.on t. dislocat.on glide and t.inning, grain boundary sliding(GBS) becomes significant.in samples wit. grain sizes below 3 μm, considerably enhancing t.e mat.rial's deformabilit.. GBS act.vat.on provides an addit.onal recovery mechanism for dislocat.ons accumulat.ng at.grain boundaries, facilit.t.ng t.eir absorpt.on during sliding and rot.t.on. Analysis of σ Θ relat.onship suggest. t.at.t.e basal slip is t.e dominant.dislocat.on mode in mg at.298K. Decreasing grain size suppresses dislocat.on act.vit. and t.inning and increases GBS, result.ng in lower Θ and σ Θ values. Suppressing convent.onal deformat.on modes coupled wit. enhanced GBS yields st.ess soft.ning, breaking down t.e Hall-Pet.h relat.onship in mg below 3 μm grain size, leading t. an inverse Hall-Pet.h behaviour. t.e work report. new dat. on t.e st.engt., duct.lit., work hardening and fract.re behaviour, and t.eir variat.ons wit. mg grain size across different.t.mperat.re regimes.

t.e aim of t.e present.st.dy was t. det.rmine t.e prevalence of bovine cyst.cercosis in bot. cat.le and buffloas, in Egypt.and t. assess t.e cyst.cidal efficacy of Balanit.s aegypt.aca fruit. (B. aegypt.aca) and moringa oleifera seeds (m. oleifera) ext.act. in experiment.lly infect.d mice. t.e st.dy det.ct.d t.e level of t.mor necrosis fact.r (t.F-α) t. monit.r t.e immune and inflammat.ry responses of experiment.lly infect.d mice. t.rough meat.inspect.on, a t.t.l number of 2125 male bovine, 2 t. 5 years old, (1125 cat.le and 1000 buffloes) were examined under t.e aut.orit. of Albsat.ne and Alwaraq official abat.oirs in Cairo Governorat., Egypt.covering t.e period ext.nded from march 2022 t. April 2023. t.e overall prevalence of t.e disease among bovine was 7.8% (6.31% of cat.le and 9.5% of buffloes). Besides, B. aegypt.aca and m. oleifera ext.act. showed cyst.cidal act.vit. in experiment.lly infect.d mice. A decrease in t.e numbers of cyst.cerci was found in all t.eat.d mice groups, and up t. 88% reduct.on was achieved in t.e B. aegypt.aca-t.eat.d group;higher t.an t.at.was recorded in bot. m. oleifera (72.23%) and albendazole-t.eat.d ones (80.56%). Post.ort.m findings proved t.at.m. oleifera and B. aegypt.aca reduced cyst.cerci numbers comparable t. a commercial ant.elmint.c. t.e st.dy showed a significant.decrease (P 0.001) in t.F-α levels aft.r t.eat.ent.wit. Balanit.s and moringa ext.act., compared wit. t.e unt.eat.d cont.ol and t.e albendazole-t.eat.d groups.
