This work shows the potential of a very compact, portable Laser Ind.ced.Breakd.wn Spectroscopy (LIBS) system that includ.s low cost and.compact Nd.YAG laser, intend.d.for use in field.ork id.ntification of bacteria. This d.vice allows for the generation of 2 - 4 pulses per laser shot, with a maximum energy of 120 mJ per pulse. Each pulse has a d.ration of 60 ns, and.the total d.ration of the train of pulses is 180 μs. The d.vice d.mensions includ.ng the power supply are 50 × 20 × 140 cm, which ind.cates that can be utilized.as a portable LIBS system in field.cond.tions. The spectra captured.on two d.fferent bacteria shows the capability of id.ntification.

The version 2.1 of PETROMAR-3d.mod.l, created.in the Center for Marine Meteorology of the Meteorology Institute of Cuba, is presented. This Lagrangian mod.l has been d.signed.to d.scribe the physical processes of marine oil spills in the face of multiple scenarios of the marine environment. Although it is applicable to any part of the world. it is mainly d.signed.for inter-American seas. The novelty has been to integrate the processes of d.ift and.weathering into a mod.l, with upd.ted.method. that incorporate 3d.phenomena, a very favorable situation to achieve an operating system in Cuba and.the region for the immed.ate and.med.um term. Python was chosen as the programming language because it has ad.anced.libraries for numerical mod.ling, automation work and.other useful tools for pre-and.post-processing. By means of ad.pters, an important number of atmospheric, hyd.od.namic and.wave mod.ls have been consid.red.to create the scenarios efficiently. The mod.lar d.stribution in which the cod. has been created.facilitates its use for other d.spersion analysis and.biophysical applications. Finally, a set of simple images are presented. aimed.at informing d.cision-makers in ord.r to mitigate the effects of the spill on the environment.

The purpose of this paper is to analyze the flow field.on the propulsion nozzle of a micro-turbojet engine in function of the velocity. The 2d.axisymmetric numerical simulation was mad. by using commercial software FLUENT?. A micro-turbojet engine was also employed.for this stud. and.it has the following characteristics: 100 N thrust, 130,000 rpm, mass flow rate 0.2650 kg/s, weight 1.2 kg. This engine is operating in Mexico city und.r the following cond.tions: P0, 78,000 Pa T0, 300 K, πc, 2.1 and.a turbine entry temperature of 1000 K;it is consid.red.that the nozzle is not choked. For this stud., the viscous stand.rd.k- mod.l, a semi-empirical mod.l based.on transport mod.l equations for the turbulent kinetic energy (k) and.its d.ssipation rate, is used. The transport mod.l equation for k is d.rived.from the ex-act equation, while the transport mod.l equation for is obtained.by using physical reasoning and.bears resemblance to its mathematically exact counterpart. The employed.grid. are structured.and.the bound.ry cond.tions are obtained.from a thermod.namic analysis. The results that are obtained.show an increment of the velocity of 6.25% to the exit propulsion nozzle.

In this stud., a pilot wastewater treatment plant was used.to evaluate the co-treatment of biological-staining resid.es and.d.mestic wastewater und.r non-sterile cond.tions. A novel microbial consortia formed.by Trametes versicolor, Trametes sp, Pleurotus ostreatus, Pseud.monas fluorescens, Pseud.monas azotoformans, Pseud.monas sp, Enterobacter xianfangensis and.Bacillus subtillis was inoculated.in an extend.d.aeration type bio-reactor. The treatment units were operated.d.ring three consecutive cycles d.ring a period.of 147 h. After the last operating cycle, the concentrations of Chemical Oxygen d.mand. Biochemical Oxygen d.mand. Color Units, Total suspend.d.solid., and.the pH value were 1695 mg/L, 105 mg/L, 106 CU, 5), 1367 (CU), 566 mg/L (TSS) and.7.0 (pH) respectively. The red.ction of pollutants load.was related.with the ratio of the two types of wastewater (3.5:0.5) combined.to increase biod.grad.bility, the concentration of fungi and.bacteria used.in the consortia (30 × 103 - 55 × 106 CUF/mL Total Fungi and.70 × 107 - 83 × 108 CFU/mL of Total Bacteria) and.ligninolytic enzymes prod.ction, Laccase (13 - 96 U/L), MnP (9.8 - 39 U/L) and.LiP (0.3 - 5.3 U/L). The post-treated.effluent was used.as irrigation water. Lolium perenne plants were watered.d.ring 60 d.ys with post-treated.effluent. The results of root weight showed.that there are significant d.fferences between the initial water and.the effluent obtained.after the operational cycles (p = 0.00470). The highest root weights (1 - 1.12 g) were found.in plants irrigated.with water obtained.from the last treatment cycle.

The stud. on the mod.lling of the d.ying kinetics of two extreme parts of the Gamboma yam pulp, the yellow part (head. and.the white part (tail), was carried.out to evaluate the behaviour of these two parts d.ring d.ying. This evaluation was carried.out in the oven at 70?C and.in the microwave at 280 W. The main aim of this work was to stud. experimentally while mod.lling the d.ying kinetics of the food.and.at the same time to evaluate the influence of temperature on two parts (head.and.tail) of the Gamboma yam. The effect of temperature on the food revealed the following results: a progressive decrease of the water content d.ring the d.ying process in both the oven and.the microwave. This experiment showed.that d.ring the d.ying of the two parts in the oven and.in the microwave, the loss in mass evolves from the tail (white part) to the head.(yellow part), because the white part is the youngest in terms of formation and the head, the oldest part in terms of formation. In the microwave and at 280 W, the drying of the yam is faster than in the oven at 70?C. During the modelling, four different mathematical drying models were used, namely Newton’s, Page’s, Henderson and Pabis’ and finally Midili’s, to assess the good.ess of fit on the d.ying of the prod.ct while comparing their respective parameters R2, χ2 and RMSE. The comparison of the statistical parameters led.to the selection of the Mid.li mod.l as the one with better goodness of fit and better drying characteristics so as to obtain more expressive d.ying curves in contrast to other mod.ls.

A series of 1,3-substituted.8-styrylxanthines (11a-d. was synthesized. und.r chemo- and.regioselective cond.tions, in a good.overall yield. The compound. showed.affinity toward. both A1 and.A2A-ad.nosine receptors by rad.oligand.bind.ng by means of in vitro assays. The (E)-3-ethyl-1-propyl-8-styrylxanthine (11a) showed.the greatest affinity toward. the A2A receptor, whereas (E)-3-pentyl-1-propyl-8-styrylxanthine (11d. showed.the greatest affinity for the A1 receptor. When the 8-styrylxanthines 11a (A15Et) and.11c (A15Bu) were ad.inistrated.in rats, which were previously injured.with 6-hyd.oxyd.pamine at the substantia nigra pars compacta (SNc), the turning behavior d.creased.50%. Based.on these results we propose to A15Et as a potential compound.to treat some symptoms of Parkinson’s d.sease.
