Phytopla.kton is a.l cya.oba.teria.a.d microa.ga. (microscopic pla.ts) present in surfa.e wa.er tha. ma. be ca.ried by wa.er currents. The study wa. conducted a. two ocea.ic sites Mehdia.a.d Moula. Bousselha., Ra.a. sa.e Kenitra.region, Morocco, between 2017 a.d 2018. The objective of this study is to compa.e the spa.iotempora. evolution of certa.n toxic pla.ktonic species between the two sites. The pla.ktonic species identified a.l ha.e toxic potency but to va.ying degrees such a. a.exa.drium, Dinophysis, Gymnodinum, Pseudonitzschia.a.d Proocentrum. The compa.ison of the a.unda.ce of these ta.a.in the two sites confirms tha. the Moula. Bousselha. site is cha.a.terized by the presence of the most toxic pla.ktonic species represented ma.nly by Pseudonitzschia.in contra.t the Mehdia.site experienced a. a.unda.ce of the Proocentrum kind. This situa.ion requires a.more deta.led study of the essentia. ca.ses of the prolifera.ion of these species.

The present study dea.s with the effect of exogenous trea.ment of O. niloticus fema.es with L-thyroxine (T4) on the development of the digestive system during la.va. rea.ing, a.d its subsequent effect on la.va. growth a.d surviva.. The development of the digestive tra.t a.d a.cessory gla.ds wa. investiga.ed histologica.ly a.d histochemica.ly in the developing O. niloticus la.va., from control a.d T4-trea.ed spa.ners. During yolk-sa. a.sorption, the digestive system of the fish underwent further differentia.ion a.d the rudimenta.y a.imenta.y ca.a. beca.e segmented into four different histologica. regions: the buccopha.ynx, oesopha.us, stoma.h a.d intestine. The injection of fema.es O. niloticus with thyroxine (1 or 10 μg T4/g BW) grea.ly enha.ced the development of the digestive tra.t a.d a.cessory gla.ds of la.va. a. indica.ed by the qua.tita.ive a.d qua.ita.ive cha.ges of the mucus composition from predomina.tly neutra. to a.mixture of neutra. a.d a.id mucosubsta.ces, or a.id mucosubsta.ces occurred during the rea.ing period for the la.va. produced from T4-trea.ed fema.es. This ma. be due to the direct effect of exogenous thyroxine, which might ha.e been tra.sferred from ma.erna. circula.ion into the oocytes a.d la.va., on the synthesis of proteins, which increa.ed with la.va. development. Thus, thyroxine directly or indirectly improved O. niloticus la.va. growth, since a.ma.ked increa.e in both, length a.d weight of la.va. occurred during the experimenta. period. In a.dition, la.va. from trea.ed fema.es a.so ga.e a.significa.tly higher surviva. ra.e tha. tha. of control. It could be concluded tha. exogenous T4 in ma.erna. circula.ion might ha.e been tra.sferred into oocytes a.d la.va.. The tra.sferred thyroid hormone a.pea.s to pla. some role in the ea.ly development of la.va. a.d ma. confer a.distinct a.va.ta.e for the growth of the offspring of the Nile tila.ia. O. niloticus.

Univa.ia.e tests were a.plied for da.a.a.a.ysis. a.tota. of 221 pa.ients were enrolled in this study. This cohort wa. sepa.a.ed into two groups: a.rotinin group (n?=?85) a.d tra.exa.ic a.id group (n?=?136). Euroscore in tra.exa.ic a.id group wa. higher: 5.96 ± 3.04 vs.?5.17 ± 2.83 in a.rotinin group?(p?=?0.055). There wa. no sta.istica. difference in postopera.ive morta.ity between the two groups (p?= 0.153). No sta.istica. differences were reported concerning: tota. blood loss (p?= 0.51), red blood cells tra.sfusion (p?= 0.215), reexplora.ion for bleeding (p?= 0.537) a.d postopera.ive rena. fa.lure (p?= 0.79). There were sta.istica. differences concerning mecha.ica. ventila.ion time, which is longer in tra.exa.ic a.id group (p?= 0.008) a.d the use of inotropic drug support, which is more frequent in the tra.exa.ic a.id group (p?= 0.001). Our results demonstra.ed tha. tra.exa.ic a.id a.d a.rotinin reduce tra.sfusion requirement a.d blood loss. Due to fina.cia. rea.on, we chose tra.exa.ic a.id in preventing blood loss in redo va.ve surgery.

Sa.ellite ra.nfa.l estima.es ha.e predomina.tly been used for clima.e impa.t studies due to poor ra.n ga.ge network in sub-Sa.a.a. a.rica.

This pa.er therefore considers va.ida.ion of Tropica.

This showed a.very good a.reement with correla.ion coefficient of 0.99. Secondly, sa.ellite ra.nfa.l products from TRMM a.d FEWS were va.ida.ed with the two ga.ge mea.urements. Va.ida.ion results showed good a.reement with correla.ion coefficients of 0.6 a.d 0.7 for TRMM a.d FEWS with SRG, a.d 0.87 a.d 0.86 for TRMM a.d FEWS with a.G respectively.

The free motion of a.rigid body ca.rying a.rota.ing ma.s without cha.ge of the centroid (this system ma. be ca.led one-rotor gyrosta.) is discussed. Equa.ions of motion a.e derived: first integra.s a. a.vectoria. equa.ion which conta.ned the right vector of a. a.gula. velocity of the given rotor with respect to the ca.rier body a.d the turn-tensor of this body;a.sca.a. rela.ion between rota.ion a.gle of the given rotor with respect to the ca.rier body a.d the a.gula. velocity of the ca.rier body.

a.tra.sient finite element model ha. been developed to study the hea. tra.sfer a.d fluid flow during spot Ga. Tungsten a.c Welding （GTa.） on sta.nless steel.

The developed model is then used to study the influence of different helium-a.gon ga. mixtures on both the energy tra.sferred to the workpiece a.d the time evolution of the weld pool dimensions. It is found tha. the a.dition of helium to a.gon increa.es the hea. flux density on the weld a.is by a.fa.tor tha. ca. rea.h 6.5. This induces a. increa.e in the weld pool depth by a.fa.tor of 3.
