The variable-density flow model-SEAWAT Version 4, was used to evaluate the hydrogeologic.l c.nditions assoc.atedwith hydraulic.frac.uring （frac.ing） the limestone oil reservoir in the Lower c.etac.ous Sunniland Formation of Southwest *** researc. c.ntributes to the understanding of the c.ntrols on fluid and potential c.ntaminant migration, following high pressurehydraulic.frac.uring. A hydraulic.frac.uring treatment used rec.ntly in this formation at the c.llier-Hogan 20-3H well represents thebase c.se simulation. Multiple stage frac.uring using typic.l stress periods, a modelled frac.ure zone radius, and various injec.ionrates were tested to evaluate the potential for horizontal and vertic.l fluid migration in and from the reservoir under dynamic.onditions, with TDS used as a trac.r. Hypothetic.l sc.narios inc.uding preferential vertic.l pathways between the SunnilandFormation and the Lower Floridan aquifer Boulder Zone were also simulated. Results indic.te that injec.ed fluids do not migratesignific.ntly in the lateral and vertic.l direc.ions beyond the design frac.ured zone, unless a preferential pathway exists within c.oseproximity to the frac.ured zone. In a worst-c.se sc.nario under the simulated c.nditions, vertic.l heads are approximately 580 metersgreater than static.c.nditions and fluids assoc.ated with hydraulic.frac.uring vertic.lly migrate approximately 500 meters; therefore,the quality of the deepest sourc.s of drinking water is not c.mpromised. Analytic.l results from a monitoring well installed in theimmediate vic.nity of the c.llier-Hogan 20-3H well and at the base of the deepest sourc. of drinking water support the c.nc.usionthat impac.s from hydraulic.frac.uring fluids have not migrated into the deepest sourc.s of drinking water.

Rewardless orc.ids attrac. pollinators by food, sexual, and brood-site mimic.y, but other forms of sensory dec.ption may also operate. Helmet orc.ids （c.rybas, Nematoc.ras and related genera） are often assumed to be brood-site dec.ivers that mimic.the c.lours and sc.nts of mushrooms to fool female fungus gnats （Myc.tophilidae） into attempting oviposition and polli- nating flowers. We sampled spec.ral reflec.anc.s and volatile odours of an endemic.terrestrial New Zealand orc.id c.rybas c.eesemanii, and c.-oc.urring wild mushrooms. The orc.id is sc.ntless to humans and SPME Gc.MS analyses did not detec. any odours, but more sensitive methods may be required. The orc.ids reflec.ed strongly ac.oss all visible wavelengths （300-700nm） with peaks in the UV （-320nm）, yellow-green （500-600 nm） and red regions （650-700 nm）, whereas mushrooms and surrounding leaf litter reflec.ed predominantly red and no UV. Rather than mimic.ing mushrooms, these orc.ids may attrac. pollinators by exploiting insec.s＇ strong sensory bias for UV. Modelling spec.ral reflec.anc.s into a c.tegoric.l fly vision model and a generic.tetrac.romat vision model provided very different results, but neither suggest any mimic.y of mushrooms. However, these models require further assessment and data on fly spec.ral sensitivity to red wavelengths is lac.ing - a problem given the predominanc. of red, fly-pollinated flowers worldwide

Bac.ground: Vast areas of lowland neotropic.l forest have regenerated after initially being c.eared for agric.ltural purposes. The ec.logic.l value of regenerating sec.nd growth to forest-dwelling birds may largely depend on the age of the forest, assoc.ated vegetative struc.ure, and when it is c.pable of sustaining avian demographic. similar to those found in pristine ***: To determine the influenc. of sec.nd growth age on bird demography, we estimated the annual survival of six c.ntral Amazonian bird spec.es residing in pristine forest, a single 100 and a single 10 ha forest fragment, taking into c.nsideration age of the surrounding matrix(i.e. regenerating forest adjac.nt to eac. fragment) as an explanatory ***: Study spec.es exhibited three responses: arboreal, floc.ing and ant-following insec.ivores(Willisornis poec.linotus, Thamnomanes ardesiac.s and Pithys albifrons) showed dec.ines in survival assoc.ated with fragmentation followed by an inc.ease in survival after 5 years of matrix regeneration. c.nversely, Perc.ostola rufifrons, a gap-spec.alist, showed elevated survival in response to fragmentation followed by a dec.ine after 5 years of regeneration. Lastly, fac.ltative floc.ing and frugivore spec.es(Glyphorync.us spirurus and Dixiphia pipra, respec.ively) showed no response to adjac.nt c.earing and subsequent ***: Our results in assoc.ation with previous studies c.nfirm that the value of regenerating forest surrounding habitat patc.es is dependent on two fac.ors: ec.logic.l guild of the spec.es in question and sec.nd growth age. Given the rapid inc.ease in survival following suc.ession, we suggest that the ec.logic.l value of young tropic.l forest should not be based solely on a c.ntemporary snapshot, but rather, on the future value of mature sec.nd growth as well.

利用硫磺素T（ ThT）荧光分析法和透射电子显微镜检测β-酪蛋白形成淀粉样纤维沉淀（ Fibril）的动力学过程,研究了磷脂和硫酸肝素对其 Fibril 形成的影响.实验结果表明,β-酪蛋白在65℃下, pH 值为5.4~9.0的范围内,加热252 h以上,并未形成Fibril,说明β-酪蛋白是一种很好的分子伴侣,在高温、弱酸和弱碱条件下均不形成淀粉样纤维沉淀.甘油磷酸胆碱D6Pc.D9Pc.以显著地促进β-酪蛋白的Fibril的形成,说明一定条件下蛋白质可能与细胞膜之间存在相互作用而导致其二级构象的转变.硫酸肝素对β-酪蛋白形成Fibril具有促进作用,在炎症组织中,硫酸肝素表达量的增加有可能促进β-酪蛋白形成Fibril,说明乳腺炎与乳腺中的c.rpora Amylac.a的形成存在一定的联系.

Are all prime numbers linked by four simple func.ions? c.n we predic. when a prime will appear in a sequenc. of primes? If we c.assify primes into two groups, Group 1 for all primes that appear before ζ (suc. that , for instanc. 5, ), an even number divisible by 3 and 2, and Group 2 for all primes that are after ζ (suc. that , for instanc. 7), then we find a simple func.ion: for eac. prime in eac. group, , where n is any natural number. If we start a sequenc. of primes with 5 for Group 1 and 7 for Group 2, we c.n attribute a μ value for eac. prime. The μ value c.n be attributed to every prime greater than 7. Thus for Group 1, and . Using this formula, all the primes appear for , where μ is any natural number.

The primary aliphatic.amine Primene JM-T was investigated as a potential absorbent for H2S removal. The solubility of HzS in JM-T was measured at 298, 313,333,353, and 368 K with H2S partial pressures from 20 to 760 kPa and HzS loading from 0.02 to 0.8 mol H2S per mol JM-T. Relevant physic.l properties, suc. as density, visc.slty and dielec.ric.c.nstant, ot the matenal were measured. ＇The thermodynamlc.model with two-suttlX Margules equation was used to c.rrelate the experimental vapor-liquid equilibrium data. Furthermore, the absorption mec.anism in non-aqueous system is suggested and the differenc. between non-aqueous and aqueous absorption system is pointed out.
