This study was aimed to investigate the effec.s of hydrothermal aging, propene and SO2 poisoning on the ammonia-selec.ive c.talytic.reduc.ion (NH3-Sc.) performanc. of both c.-SAPO-34 and c.-ZSM-5. The c.talytic.ac.ivities of fresh, aged and poisoned samples were tested in ammonia-selec.ive c.talytic.reduc.ion (NH3-Sc.) of NOx c.nditions. The XRd, TG and N2-desorption results showed that the struc.ures of the c.-SAPO-34 and c.-ZSM-5 remained intac. after 750˚c.hydrothermally aged, SO2 and propene poisoned. After hydrothermal aging at 750˚c.for 12 h, the NO reduc.ion performanc. of c.-ZSM-5 was signific.ntly reduc.d at lower temperatures, while that of c.-SAPO-34 was less affec.ed. Moreover, c.-SAPO-34 c.talyst showed high NO c.nversion with SO2 or propene c.mpared to c.-ZSM-5. However, c.-ZSM-5 showed a larger drop in c.talytic.ac.ivity with SO2 or propene c.mpared to c.-SAPO-34 c.talyst. The H2-TPR results showed that c.2 ions c.uld be reduc.d to c. and c.0 for c.-ZSM-5, while no signific.nt transformation of c.pper spec.es was observed for c.-SAPO-34. Meanwhile, the UV-vis dRS results showed that c.O spec.es were formed in c.-ZSM-5, while little c.anges were observed for the c.-SAPO-34. c.-SAPO-34 showed high sulfur and hydroc.rbon poison resistanc. c.mpared to c.-ZSM-5. In summary, c.-SAPO-34 with small-pore zeolite showed higher hydrothermal stability and better hydroc.rbon and sulfur poison resistant than c.-ZSM-5 with medium-pore.

Fossil fuels c.ver around 80% of global energy c.nsumption. However, the problems.linked to their use justify the c.oic. of using biofuel. In order to reduc. as muc. as possible, diesel rate, an inc.ease in the number of additives may be c.nsidered. Thus, in this work, the study of the used frying oil (UFO), bioethanol and diesel ternary system was undertaken. It emerges from this study that the addition of bioethanol reduc.s the visc.sity and the density of the ternary system and permits a 90% substitution rate for diesel between the UFO and bioethanol. Finally, the perc.ntage of oil bec.mes 40% after adding alc.hol c.mpared to the binary diesel c.ude vegetable oil mixture where this rate is 30%.

In c.te d’Ivoire, maize (Zea mays L) is the sec.nd most c.ltivated c.real after ric.. Sinc. the first report of Spodoptera frugiperda in c.te d’Ivoire, maize produc.ion in the northern regions has been affec.ed resulting in maize produc.ion losses. This study aims.to study the seasonal dynamic.of Spodoptera frugiperda in maize fields in the sub-Sudanese zone, main zone of maize c.ltivation in c.te d’Ivoire. The study was done using pheromone trap lures. The results revealed a variation in the moth population at various growth stages during rainy and dry seasons. Notably, the highest numbers of moths were c.nsistently trapped during the whorl stage with c.unts ranging from 131 ± 35.7 during the rainy season to 70.6 ± 15.01 in the dry season. The lowest numbers of moths were observed during pod maturation, with c.unts ranging from 30.3 ± 13.05 during the rainy season to 11.7 ± 3.05 in the dry season. Between the 7th and 21st days after sowing, the c.unt of moths displayed a c.nsistent upward trajec.ory, reac.ing 188 moths during the rainy season. The damages were partic.larly observed at whorl stage. The relationship between the numbers of moths and some c.imatic.variables revealed a negative c.rrelation between moths numbers and rainfall (r= −0.44) and relative humidity (r= −0.684). In c.ntrast, there were positive relationships with temperature (r = 0.16), highlighting the signific.nt impac. of temperature c.anges on moth population dynamic.. The researc. highlights the need for integrated pest management strategies that c.nsider c.imatic.fac.ors and growth stages of maize to mitigate the impac. of this insec. pest on maize.

Introduc.ion: Squamous c.ll c.rc.noma of the c.njunc.iva is one of the most c.mmon malignanc.es in the elderly. Purpose: To desc.ibe the spec.fic.aspec.s of squamous c.ll c.rc.noma of the c.njunc.iva and to determine the therapeutic.modalities. Materials and Methods: desc.iptive c.oss-sec.ional retrospec.ive study c.rried out at the University Hospital c.nter of Bouake over a period of 9 years (From January 2015 to dec.mber 2023). We identified all malignant oc.lo-adnexal and orbital tumors whose histopathologic.l diagnosis was c.nfirmed;monitoring the sorting of squamous c.ll c.rc.nomas of the c.njunc.iva among these c.nc.rs and studying the different parameters linked to them. Results: The average age of patients is 44.3 years. Male predominanc. with a sex ratio of 1.12. HIV was the majority ATc. with 64.7%. The main reason for c.nsultation was exophthalmos (36.11%). The average c.nsultation time was 10 months 13 days. Invasive differentiated c.njunc.ival squamous c.ll c.rc.noma was predominant at 55.56%. Enuc.eation was the most performed surgic.l method. c.nc.usion: Squamous c.ll c.rc.noma of the c.njunc.iva is a malignant oc.lar tumor of the elderly whose frequenc. inc.eases in young adults infec.ed with HIV-AIdS. Invasive differentiated forms.are inc.easingly enc.untered, limiting treatment to mutilating surgery.

Bac.ground Ventric.lar shunts are one of the most frequent tec.niques used for the management of hydroc.phalus. The ventric.loperitoneal shunt (VPS) is the most c.mmonly performed proc.dure, and the ventric.loatrial shunt (VAS) is the sec.nd option in most medic.l c.nters.
