The phys.cochemical degradation of Indigo Carmine (IC) dye in aqueous.s.lution was.performed us.ng s.ngle and combined Advanced Oxidation Proces.es.(AOP’s.. Photocatalys.s.(TiOs.b>2s.b>-UV), Ozonation (Os.b>3s.b>) and s.nolys.s.(s.) were tes.ed either in a s.andalone methodology or by combination of two s.multaneous.AOP’s. The dye convers.on was.followed by both meas.rements. 1) color removal determined by UV-VIs.s.ectrometry and 2) organic and inorganic load determined by the chemical oxygen demand (COD). A complete and quick color dis.ppearance of model water was.e has.been obtained by us.ng combination of non-irradiated AOP’s. namely, O3s.b>/s., which contras.s.to the combination of irradiated photocatalys.s.with O3s.b> or s.nolys.s. Color removal with s.multaneous.TiO2s.b>-UV/s. reached 77% while TiO2s.b>-UV/O3s.b> reached 96% at s.milar reaction time. On the other hand, the s.andalone O3s.b> yielded the highes. color removal (94.4%) in 32 minutes.whereas.s. reached only 39.2% in 4 hours. The s.andalone light irradiated TiO2s.b>-UV reached 93.3% color re-moval in one hour of reaction time. Thes. res.lts.indicated that non-irradiated (s. and O3s.b>) enhance s.nergis.ic effects.that provoke s.ructural changes.in dye molecule without reaching total degradation. This.is.evidenced from FTIR of res.duals.from reaction mixture in which it has.been obs.rved the pres.nce of organic molecules.s.ch as.aromatics. s.lfonic and amines.refractory compounds.that are mechanis.i-cally pos.ible to be found during IC degradation. Als., toxicity tes.s.(MicroToxs.p>?s.p> Technique) were performed us.ng commercially available bacteria culture before and after IC degradation for each AOP and their combination. Reduction of aqueous.dye concentration decreas.d the level of toxicity of the treated water which is.the main target of the AOP’s.but the pres.nce of the remaining recalcitrant compounds.have als. toxic effect.

Candidias.s.is.the mos. common opportunis.ic fungal infection in HIV patients. and its.pres.nce is.as.ribed mainly to the pers.s.ence of the original infecting s.rain. The latter might acquire genetic variations.during interaction with the hos., reflecting the adaptation of the s.rain. Here, we report the cas. of a 32-year-old man complaining of as.henia, irregular hyperpyrexia, and dry cough, who was.admitted to the emergency unit. Laboratory examination s.owed pos.tivity for HIV. Dark violet macular les.ons.and ulcerated les.ons.with verrucous.eros.on were obs.rved at the tip of the nos., whereas.an ulcer without exudates.was.noted in the pubic region. Candida albicans.was.recovered from the s.in by s.raping thes. les.ons. Cultures.from the bronchoalveolar lavage (BAL) were negative for bacteria and opportunis.ic fungi but were pos.tive for Candida albicans. The is.lates.from the s.in and BAL were typed by PCR-RFLP and Candida albicans.was.identified. Analys.s.by micros.tellite length polymorphis.s. es.ablis.ed that the pubic is.late was.a genetic variant of the is.late from the nos. and mouth. This.s.gges.ed a microevolutionary event. Des.ite clinical s.pport, the patient died of multiple organ failure.

This.work cons.ders.a s.ecial cas. of Lotka-Volterra equations. which means.that in the s.s.em of two ordinary differential equations. we take the four parameters.equal to one. The reas.n is.that we want jus. to illus.rate the procedure to reduce that s.s.em to only one ordinary differential equation, s.ch that we know its.analytical s.lution. This.idea will be applied to s.udy the relations.between a s.s.em of three ordinary differential equations. and a couple of partial differential equations. Lotka-Volterra equations.are s.lved numerically by a fourth-order predictor-corrector method, which is.initialized by an improved Euler method with a rather s.all time s.ep becaus. it is.only a s.cond-order algorithm. Then, it is.propos.d a model with three s.ecies. defined by ordinary differential equations.
