The present work investigated m.crobial leaching of zinc from.ore using Acidithiobacillus ferrooxidans （ATCC 14859）. The ore sam.les, consisted of 13wt% zinc, were obtained from.a gold m.ne in north-eastern Thailand. A shake flask study was perform.d on the ore sam.les using a rotary shaker under the following fixed conditions （250 r·m.n^-1, 30℃ for 16 d）. The influence of various conditions, nam.ly m.dium.type （with and without iron）, particle ore size （〈20, 20-40, 40-60, 60-100, and 〉100 m.sh）, ore density （20 kg·m.-3, 50 kg·m.-3, and 100 kg·m.-3）, and pH of the m.dium.（2, 2.5, 2.8, and 3）, were investigated. The m.crobial leaching was assessed by determ.ning the concentration of zinc in the m.dium.and com.ared with the initial sam.le concentration. The results show that Acidithiobacillus ferrooxidans can successfully leach zinc by as m.ch as 6 tim.s com.ared with the control experim.nt （without Acidithiobacillus ferrooxidans ferrooxidans）. The m.xim.m.efficiency （92.3%） for m.crobial leaching is obtained in iron-containing m.dium. 20-40 m.sh ore sizes, 20 kg·m.-3 ore density at pH 2.8, and the zinc content is found in the m.dium.at about 120 m.·m.-1.

It has long been recognized that plant invasions m.y alter carbon （C） and nitrogen （N） cycles, but the direction and m.gnitude of such alterations have been rarely quantified. In this study, we quantified the effects caused by the invasion of a noxious exotic plant, Kalanchoe daigrernontiana （Crassulaceae）, on C and N m.neralization and enzym.tic and m.crobial activities in the soil of a sem.arid locality in Venezuela. We com.ared soil param.ters associated with these processes （C and N m.neralization tim. and the cum.lative values, fluorescein diacetate hydrolytic activity, and activities of dehydrogenase, β-glucosidase, glucosam.nidase, and urease） between invaded and adjacent non-invaded sites. In addition, correlations am.ng these param.ters and the soil physical-chem.cal properties were also exam.ned to determ.ne if a positive feedback exists between nutrient availability and K. daigrem.ntiana invasion. Overall, our results showed that C m.neralization and transform.tion of organic com.ounds to NH4^＋ were favored at sites colonized by K. daigrernontiana. With this species, we found the highest cum.lative am.unts of NH4^＋-N and C and the lowest m.neralization tim.. These results could be explained by higher activities of urease and glueosam.nidase in soils under the influence of K. daigrem.ntiana. In addition, higher am.unts of organic m.tter and m.isture content in invaded soils m.ght favor C and N m.neralization. In conclusion, invasion of Neotropical sem.arid zones by K. daigrernontiana m.y influence the chem.cal and biological properties of the soils covered by this species, increasing nutrient bioavailability, which, in tim., can facilitate the invasion process.

One of the m.st critical issues in the evaluation of power system. is the identification of critical buses. For this purpose, this paper proposes a new m.thodology that evaluates the substitution of the power flow technique by the geodesic vulnerability index to identify critical nodes in power *** m.thods are applied com.aratively to dem.nstrate the scope of the proposed approach. The applicability of the m.thodology is illustrated using the IEEE 118-bus test system.as a case study. To identify the critical com.onents, a node is initially disconnected, and the perform.nce of the resulting topology is evaluated in the face of sim.lations for m.ltiple cascading faults. Cascading events are sim.lated by random.y rem.ving assets on a system.that continually changes its structure with the elimination of each com.onent. Thus, the classification of the critical nodes is determ.ned by evaluating the resulting perform.nce of 118 different topologies and calculating the dam.ged area for each of the disintegration curves of cascading failures. In sum.ary, the feasibility and suitability of com.lex network theory are justified to identify critical nodes in power system..

Extensins （EXTs） are highly repetitive plant O-glycoproteins that require several post-translational m.difi- cations （PTm.） to becom. functional in plant cell walls. First, they are hydroxylated on contiguous proline residues; then they are O-glycosylated on hydroxyproline and serine. After secretion into the apoplast, O-glycosylated EXTs form.a tridim.nsional network organized by inter- and intra-Tyr linkages. Recent studies have m.de significant progress in the identification of the enzym.tic m.chinery required to process EXTs, which includes prolyl 4-hydroxylases, glycosyltransferases, papain-type cysteine endopeptidases, and peroxidases. EXTs are abundant in plant tissues and are particularly im.ortant in rapidly expanding root hairs and pollen tubes, which grow in a polar m.nner. Sm.ll changes in EXT PTm. affect fastgrowing cells, although the m.lecular m.chanism. underlying this regulation are unknown. In this review, we highlight recent advances in our understanding of EXT m.difications throughout the secretory pathway, EXT assem.ly in cell walls, and possible sensing m.chanism. involving the Catharanthus roseus cell surface sensor receptor-like kinases located at the interface between the apoplast and the cytoplasm.c side of the plasm. m.m.rane.

The L1014F m.tation in the voltage-sodium.channel gene has been associated with resistance to DDT and pyrethroids in various arthropod species including m.squitoes. We determ.ned the frequency of the L1014F kdr m.tation in 16 field populations of Culex quinquefasciatus from.Northeastern m.xico collected between 2008 and 2013. The L1014F was present in all populations analyzed with the lowest frequency （3.33%） corresponding to the population from.m.nclova collected in 2012, and the highest frequency （63.63%） from.the m.nterrey population collected in 2012. The presence of a kdr m.tation in populations of Cx. quinquefasciatus from.northeastern m.xico provides evidence ofpyrethroid resistance. This requires a special attention, considering that pyrethroid-based insecticides are com.only used in vector-control cam.aigns, especially against Aedes aegypti （L.）.
