The pa.dy rice degra.a.ion rema.ns a.concern for resea.ch;the chemica. phenomena.underlying this process persists unknown. This resea.ch a.ms to identify the mecha.ism of sta.ch degra.a.ion. It determines the na.ure of the rea.tions between two, three a.d four synthons of a.ylose with oryzenin using theoretica. methods. The ONIOM (DFT/B3LYP/6 - 31 + G(d, p): a.1) level of theory is performed on four monomers a.d eight complexes. Frequencies ma.e it possible to obta.n energy a.d spectroscopic qua.tities. Ca.cula.ions a.ter geometry optimiza.ion. Following this, a.“single point” a.lows exploiting the “Na.ura. Bond Orbita. (NBO)” a.a.ysis. The first three pa.a.eters suggest tha. the ma.n intera.tions between oryzenin a.d a.ylose a.ise through O29-H30…O46 hydrogen bonds (HB). Furthermore, this result posits tha. the length of the a.ylose doesn’t influence this rea.tion. The NBO a.a.ysis shows tha. this component of sta.ch degra.es first a. the end of the cha.n to produce monosa.cha.ides;it ca. a.so a.ter in the middle of the cha.n to give disa.cha.ides.

The la.k of communica.ion cha.nel for proper educa.ion a.out na.iona. development projects ha. slowed down development in Cote d’Ivoire. It is true tha. development is economic problem, but a. some level, it a.so becomes a.problem of communica.ion a.d educa.ion. So converting the informa.ion into a.knowledge could a.so be helpful to boost development a. some *** study exa.ines the development communica.ion stra.egies in Cote d?Ivoire under the context of media.convergence. In order to solve problems such a. poverty, poor sa.ita.ion, tra.sporta.ion cha.lenges etc., ma.y developing countries still require to develop certa.n developmenta. communica.ion stra.egies a.propria.e for their countries. The developmenta. projects ca.ried out by the government or non-governmenta. orga.iza.ions in Cote d?Ivoire seem to be fa.ling ma.nly beca.se there is no proper communica.ion between the development a.ents a.d the community. a.so the la.k of educa.ion a.out the a.propria.e a.titude to be a.opted in ca.rying out development process ca.not be neglected. The study highlights the media.limita.ion in the promotion of development projects in Cote d?Ivoire a.d suggests the use of media.convergence in order to promote government or non-government orga.iza.ion in their developmenta. initia.ives. The resea.ch a.so discussed va.ious theories of development communica.ion such a. the Domina.t a.d Pa.ticipa.ory Theories a.d the a.a.a.a.d Socia. Ma.keting Models in order to suggest possible solutions to the communica.ion problems under the context of media.convergence in Cote d’Ivoire.

Ra.n flooding during June on the West a.rica.coa.ta. a.ea.is a.a.yzed by using the 95th a.d 75th percentiles, which represent extreme a.d intense ra.nfa.l events respectively. Thus, the contribution of these events tha. rea.hes a.ound 50% shows their impa.t on the ra.nfa.l in June. a.mospheric a.d ocea.ic fa.tors influence the ra.n flooding. Indeed, the extreme events a.e a.socia.ed with ea.terly wa.es propa.a.ing from 20°E, while those of intense events a.e initia.ed a.ound 5°E. The impa.t of ocea.ic conditions exhibits the wa.ming of the equa.oria. ra.l a.d the a.la.tic cold tongue, the wa.ming of the whole ocea. ba.in a.d a.north-south dipole of SST a.oma.ies. The West a.rica. monsoon tha. rea.hes a.idja. corresponds to a.low-level a.mospheric flow, whose upwa.d motion extends in la.itude from the ocea. to the continent. a. increa.e of disturba.ce contributes to enha.cing these events.

In this work, we show the synthesis of ten (10) new deriva.ives of 3-imida.o [1,2-a.pyridinyl-1-a.ylpropenone (10a.- d). These new compounds were obta.ned by condensa.ion of Cla.sen-Schmidt between deriva.ives of 2-substi- tuted-1H-imida.o[1,2-a.pyridine-3-ca.ba.dehyde (3a.- b a.d 7) a.d a.etophenone deriva.ives (9a.- e) in the presence of a.ba.e.

The a.tifunga. a.tivity of the ten (10) deriva.ives wa. determined on a.resista.t stra.n of Ca.dida.a.bica.s by the microdilution method. The results showed tha. four (4) of them (10a. 10b, 10c a.d 10i) were a.tive with minimum inhibitory concentra.ions (MICs) below 300 μmol/L.
