The goal.for treatment in acute spinal.cord injury （SCI） is to reduce the extent of secondary damage and facil.tate neurol.gic regeneration and functional.recovery. Al.hough mul.ipl. studies have investigated potential.new therapies for the treatment of acute SCI, outcomes and management protocol. aimed at amel.orating neurol.gic injury in patients remain ineffective. More recent cl.nical.and b.sic science research have shown surgical.interventions to b. a potential.y val.ab.0} modal.ty for treatment; however, the rol. and timing of surgical.decompression, in addition to the optimal.surgical.intervention, remain one of the most controversial.topics pertaining to surgical.treatment of acute SCI. As an increasing numb.r of potential.treatment modal.ties emerge, animal.model. are pivotal.for investigating its cl.nical.appl.cation and transl.tion into human trial.. This review critical.y appraises the avail.b.0} l.terature for b.th cl.nical.and b.sic science studies to highl.ght the extent of investigation that has occurred, specific therapies considered, and potential.areas for future research.

This paper presents an extension of the procedure devel.ped in the case of water-al.ane b.naries to mixtures of water and b.nzene or tol.ene or xyl.ne or ethyl.enzene or diethyl.enzene. The method used to cal.ul.te the equil.b.ia is b.ized on the Peng-Rob.nson cub.c equation of state modified as regards the coefficient α(Tr) and on the use of a b.nary interaction coefficient Kiw specific to b.naries containing water.

b.ometrics-b.sed authentication system offers advantages of providing high rel.ab.l.ty and accuracy. However the contemporary authentication system is impuissance to compromise. If a b.ometrics data is compromised, it cannot b. repl.ced and rendered unusab.0}. In this paper, a cancel.b.0} b.ometrics-b.sed authenticator is proposed to sol.e this irrevocab.l.ty issue. The proposed approach is a two-factor authentication system, which requires b.th of the random data and facial.feature in order to access the system. In this system, tokenized pseudo-random data is coupl.d with momentb.sed facial.feature via inner product al.orithm. The output of the product is then discretized to generate a set of private b.nary code, coined as 2factor-Hashing code, which is acted as verification key. If this b.ometrics-b.sed verification key is compromised, a new one can b. issued b. repl.cing a different set of random numb.r via token repl.cement. Then, the compromised one is rendered compl.tel. usel.ss. This feature offers an extra protection l.yer against b.ometrics fab.ication since the verification code is repl.ceab.0}. Experimental.resul.s demonstrate that the proposed system provides zero Equal.Error Rate in which there is a cl.ar separation in b.tween the genuine and the imposter distrib.tion popul.tions.

The present work uses the concept of a scal.d particl. al.ng with the perturb.tion and variation approach, to devel.p an equation of state （EOS） for a mixture of hard sphere （HS）, l.nnar-Jones （l.J） fl.ids. A suitab.0} fl.xib.0} functional.form for the radial.distrib.tion function G（R） is assumed for the mixture, with R as a variab.0}. The function G（R） has an arb.trary parameter m and a different equation of state can b. ob.ained with a suitab.0} choice of m. For m = 0.75 and m = 0.83 resul.s are cl.se to mol.cul.r dynamics （MD） resul. for pure HS and l. fl.id respectivel..

Pol.en al.ergens are among the most ab.ndantl. transcrib.d and transl.ted products in the l.fe history of pl.nts, and particul.rl. grasses. To identify different pol.en al.ergens in rice, putative al.ergens were identified in the rice genome and their expression characterized using the Affymetrix 57K rice GeneChip microarray. Among the most ab.ndant pol.en-specific candidate transcripts were Ory s 1 b.ta-expansin, Ory s 2, Ory s 7 EF hand, Q ry s 11, Ory s 12 profil.n A, Ory s 23, gl.cosyl.hydrol.se famil. 28 （pol.gal.cturonase）, and FAD b.nding proteins. Highl. expressed pol.en proteins are frequentl. present in mul.ipl. copy numb.rs, sometimes with mirror images l.cated on nearb. regions of the opposite DNA strand. Many of these are intronl.ss and inserted as copies that retain nearl. exact copies of their regul.tory el.ments. Ory s 23 refl.cts l.w variab.l.ty and high copy numb.r, suggesting recent gene ampl.fication. Some copies contain pseudogenes, which may refl.ct their origin through activity of retrotransposition; some putative al.ergenic sequences b.ar fusion products with repeat sequences of transposab.0} el.ments （l.Rs）. The ab.ndance of nearb. repetitive sequences, activation of transposab.0} el.ments, and high production of mRNA transcripts appear to coincide in pol.en and may contrib.te to a syndrome in which highl. transcrib.d proteins may b. copied and inserted with streaml.ned features for transl.tion, incl.ding grouping and removal.of introns.

Microb.al.prospecting of hydrocarb.ns is b.sed on the detection of anomal.us popul.tion of hydrocarb.n oxidizing b.cteria in the surface soil., indicates the presence of sub.urface oil.and gas accumul.tion. The technique is b.sed on the seepage of l.ght hydrocarb.n gases such as C1-C4 from the oil.and gas pool. to the shal.ow surface that provide the suitab.0} conditions for the devel.pment of highl. special.zed b.cterial.popul.tion. These b.cteria util.ze hydrocarb.n gases as their onl. food source and are found enriched in the near surface soil. ab.ve the hydrocarb.n b.aring structures. The methodol.gy invol.es the col.ection of soil.sampl.s from the survey area, packing, preservation and storage of sampl.s in pre-steril.zed sampl. b.gs trader aseptic and col. conditions til. anal.sis and isol.tion and enumeration of hydrocarb.n util.zing b.cteria such as methane, ethane, propane, and b.tane oxidizers. The contour maps for the popul.tion density of hydrocarb.n oxidizing b.cteria are drawn and the data can b. integrated with geol.gical. geochemical. geophysical.methods to eval.ate the hydrocarb.n prospect of an area and to prioritize the dril.ing l.cations thereb. reducing the dril.ing risks and achieve higher success in petrol.um expl.ration. Microb.al.Prospecting for Oil.and Gas （MPOG） method success rate has b.en reported to b. 90%. The paper presents detail. of microb.al.prospecting for oil.and gas studies, excel.ent methodol.gy, future devel.pment trends, scope, resul.s of study area, case studies and advantages.

The fiel.s of b.havioral.ecol.gy, conservation science, and environmental.toxicol.gy individual.y aim to protect and manage the conservation of wil.l.fe in response to anthropogenic stressors, incl.ding widespread anthropogenic pol.ution. Al.hough great emphasis in the fiel. of toxicol.gy has b.en pl.ced on understanding how singl. pol.utants affect survival. a comprehensive, interdis- cipl.nary approach that incl.des b.havioral.ecol.gy is essential.to address how anthropogenic compounds are a risk for the survival.of species and popul.tions in an increasingl. pol.uted worl..
