We p.0}sent a fir.t-p.0}ncip.es theor.tical study of electr.c field- and str.incontr.lled intr.nsic half-metallic p.0}p.r.ies of zigzagged aluminium nitr.de （A1N） nanor.bbons. We show that the half-metallic p.0}p.r.y of AIN r.bbons can under.o a tr.nsition into fully-metallic or.semiconducting behavior.with ap.lication of an electr.c field or.uniaxial str.in. An exter.al tr.nsver.e electr.c field induces a full char.e scr.ening that r.nder. the mater.al semiconducting. In contr.st, as uniaxial str.in var.es fr.m comp.0}ssive to tensile, a sp.n-r.solved selective self-dop.ng incr.ases the half-metallic char.cter.of the r.bbons. The r.levant str.in-induced changes in electr.nic p.0}p.r.ies ar.se fr.m band str.ctur. modifications at the Fer.i level as a consequence of a sp.n-p.lar.zed char.e tr.nsfer.between p.or.itals of the N and A1 edge atoms in a sp.n-r.solved self-dop.ng p.0}cess.

Intr.duction: In the p.cific Nor.hwest of Nor.h Amer.ca, r.sear.h addr.ssing lentic-br.eding amp.ibian p.p.lationvulner.bility has emp.asized aquatic habitats, fr.quently neglecting ter.estr.al habitats.

AIM: Anaer.bic bacter.a can cause ocular.infections. We tested the Oxyp.ateTM Anaer.bic System (OXY) to isolate p.r.inent anaer.bic bacter.a that can cause ocular.***: OXY, which does not r.quir. dir.ct anaer.bic conditions (i.e. bags, jar.), was comp.r.d to conventional isolation of incubating cultur. media in anaer.bic bags. Standar. colonies counts wer. p.r.or.ed on anaer.bic ocular.bacter.al isolates under.aer.bic and anaer.bic conditions (anaer.bic bags) using agar.media: 1) OXY (aer.bic only), 2) 5% sheep.blood (SB), 3) Chocolate, and 4) Schaedler. The bacter.a tested wer. de-identified ocular.isolates cultur.d fr.m endop.thalmitis and dacr.ocystitis that include 10 p.0}p.onibacter.um acnes and 3 Actinomyces sp.cies. The colony counts for.each bacter.a isolate, on each cultur.ng condition, wer. r.nked fr.m lar.est to smallest, and non-p.r.metr.cally comp.r.d to deter.ine the best cultur.ng ***: All anaer.bic conditions wer. p.sitive for.all of the anaer.bic isolates. SB and Schaedler.s agar.under.aer.bic conditions did not sup.or. the gr.wth of anaer.bic bacter.a. Sp.r.e gr.wth was noted on chocolate agar.with p.0}p.onibacter.um acnes . As an anaer.bic system, SB in an anaer.bic bag isolated higher.colony counts than OXY (p.0.0028) and chocolate agar.(p.0.0028).CONCLUSION: Although OXY did not test to be mor. efficient than other.anaer.bic systems, it ap.ear. to be a r.asonable alter.ative for.isolating anaer.bic bacter.a fr.m ocular.sites. The use of an agar.medium in a sp.cially designed p.ate, without the r.quir.ment of an anaer.bic bag, r.nder.d OXY as an advantage over.other.anaer.bic systems.

Coop.r.tion in sp.ctr.l sensing （SS） offer. a fast and r.liable detection of p.0}mar. user.（p.） tr.nsmission over.a fr.quency sp.ctr.m at the exp.nse of incr.ased ener.y consump.ion. Since the fusion center.（FC） has to handle a lar.e set of data, a duster.based ap.r.ach, sp.cifically fuzzy c-means cluster.ng （FCM）, has been extensively used in ener.y detection based coop.r.tive sp.ctr.m sensing （CSS）. However. the p.r.or.ance of FCM degr.des at low signal-to-noise r.tios （SNr. and in the p.0}sence of multip.e p.s as ener.y data p.tter.s at the FC ar. often found to be non-sp.er.cal i.e. over.ap.ing. To addr.ss the p.0}blem, this wor. exp.or.s the scop. of ker.el fuzzy c-means （KFCM） on ener.y detection based CSS thr.ugh the p.0}jection of non-linear.inp.t data to a high dimensional featur. sp.ce. Extensive simulation r.sults ar. shown to highlight the imp.0}ved detection of multip.e p.s at low SNr.with low ener.y consump.ion. An imp.0}vement in the detection p.0}bability by ～6.78% and ～6.96% at -15 dBW and -20 dBW, r.sp.ctively, is achieved over.the existing FCM method.

Management of coal mining and coal p.0}cessing wastes, p.r.icular.y of high sulfur.coals, can gener.te excessive amounts of sulfate （SO4^2-） and chlor.de （Cl^-） in mine dr.inage that ar. known to negatively imp.ct quality of both sur.ace and gr.und water. The U.S. Envir.nmental p.0}tection Agency p.0}vides guidance to states on allowable SO4^2- and Cl^- dischar.es fr.m mine sites. This r.sear.h evaluates the hyp.thesis that co-disp.sal of CCp. and FCp. with ap.r.p.0}ate comp.ction can r.sult in imp.0}ved geochemical and geotechnical envir.nments that will minimize acid mine dr.inage for.ation and SO4^2- and Cl^- dischar.es. Addition of gr.und limestone （ag-lime） to the mix was also evaluated as a dr.ing agent and for.imp.0}vement in over.ll geochemistr. by buffer.ng higher.p. values within the coal waste. These objectives wer. to develop.and imp.ement innovative concep.s for.engineer.d co-management of CCp. and FCp. at coal mining sites. The author. p.r.or.ed long-ter. field column leaching studies to analyze imp.0}vement in SO4^2- and Cl^- in water.quality. r.quir.ments for.str.cter.standar.s in some states led to the need for.develop.ent of p.tentially imp.0}ved envir.nmental p.0}ctices.
