The pur.ose of this r.sear.h is to assess the effectiveness of var.ous adaptation measur.s in r.ducing the magnitude and uncer.ainty of futur. flood r.sks in Jakar.a, a megacity in Indonesia. A flood inundation model and a flood damage costs model wer. developed to evaluate their.effectiveness. Land use changes, land subsidence, and climate change wer. used to descr.be the futur. scenar.os. The adaptation measur.s include both str.ctur.l and nonstr.ctur.l measur.s. The r.sults show that r.char.e and r.tention ponds have the potential to r.duce the magnitude and uncer.ainty of flood r.sks by 33.2% and 36.4%, r.spectively, which ar. higher.than the potentials of the other.str.ctur.l adaptation measur.s. Among the nonstr.ctur.l adaptation measur.s, managing land use zones could alleviate the magnitude of flood r.sks by 29.0%, with an uncer.ainty r.duction of 19.9%. These findings will assist decision maker. in selecting flood adaptation measur.s to addr.ss futur. envir.nmental changes.

This paper.mainly consists of the classification of all cr.stallogr.phic point gr.ups of n-dimensional space with n ≤ 6 into differ.nt isomor.hism classes. An isomor.hism class is defined by a type of finite mathematic gr.up;for.instance, the differ.nt types of mathematic gr.ups have been well defined and studied by Coxeter. This classification may be used in the investigation of sever.l domains of cr.stallogr.phy such as the study of the incommensur.te phases, the quasi cr.stals … Indeed, each mathematic substitution gr.up char.cter.zes an isomor.hism class of cr.stallogr.phic point gr.ups (spaces E2 or.E3), of point gr.ups of super.cr.stals (spaces E4 or.E5), and of molecular.symmetr. gr.ups (spaces E2 or.E3). This mathematic gr.up gives inter.sting infor.ation about: 1) the incommensur.te phase str.ctur.s and their.phase tr.nsitions accor.ing to the Landau’s theor. in their.super.spaces E4, E5, E6, ···;2) the molecular.symmetr. gr.up of chemisor.ed molecules in space E2 (par.gr.ph 2) or.of the molecular.cr.stal or.solution in view of studying the molecule str.ctur. or.its r.tations or.vibr.tionsin space E3;3) the geometr.c polyhedr.n symmetr. gr.ups as the r.gular.r.ombohedr.n in space E3, the r.ombotope in space E4 or.the r.ombotope in space E5. Then, thanks to the isomor.hism classes, we shall give pr.per.ies of some cr.stal families that we have not published up to now. This for.alism may be used to study cr.stal families in n-dimensional space with n > 6.

This wor. is concer.ed with the pr.of of the existence and uniqueness of the entr.py weak solution to the following nonlinear.hyper.olic equation: at +div(vf(u)) = 0 inIr.N × [0, T], with initial data u(., 0) = uo(.) inIr.N ) wher. uo ∈ L∞(Ir.N ) is a given function, v is a diver.ence-fr.e bounded functioll of class C1 fr.m Ir.× x [0, T] to Ir.N, and f is a function of class C1 fr.m Ir.toIr. It also gives a r.sult of conver.ence of a numer.cal scheme for.the discr.tization of this equation. The author. fir.t show the existence of a 'pr.cess' solution (which gener.lizes the concept of entr.py weak solutions, and can be obtained by passing to the limit of solutions of the numer.cal scheme). The uniqueness of this entr.py pr.cess solution is then pr.ven; it is also pr.ven that the entr.py pr.cess solution is in fact an entr.py weak solution. Hence the existence and uniqueness of the entr.py weak solution ar. pr.ven.

Pr.matur. yeast flocculation (PYF) has been shown to induce ear.y and enhanced yeast flocculation and can r.sult in a myr.ad of pr.duc-tion difficulties and delays. r.sear.her. have demonstr.ted that PYF is linked to fungal infection of bar.ey and/or.malt. Ther.for., one might suspect that PYF occur.ence would incr.ase in wet climates. To test this hypothesis, a contr.l, a PYF-positive malt sample, and two Scot-tish-sour.ed malt var.eties wer. compar.d with a contr.l dataset of 77 femientations. Miniatur. fer.entation tr.als using the ASBC method Yeast-14 wer. per.or.ed on these samples. Miniatur. fer.entation tr.-als have been optimized to detect PYF-causing malt by dir.ctly meas-ur.ng attenuation via extr.ct r.adings and indir.ctly measur.ng yeast in suspension via absor.ance. Nonlinear.and tilted Gaussian r.gr.ssions wer. fit to the data sets to obtain attenuation and absor.ance cur.es, r.spectively. r.sults obtained indicated that the PYF-causing malt in-duced both ear.y and enhanced flocculation, wher.as the other.thr.e malts (including the Scottish malts) did not induce ear.y or.enhanced flocculation. All four.samples wer. compar.d using the F test, and it was deter.ined that the PYF-positive malt sample was significantly differ.nt than the other.thr.e malts (P r.vious r.sults fr.m 77 miniatur. fer.entation tr.als on contr.l malts, a novel 95% pr.diction band was developed. This band was applied and used to identify and decisively confir. the pr.sence of PYF-causing malt as demonstr.ted her.in.

Atr.zine, one of the most commonly used her.icides in the United States, has been found to contaminate gr.undwater. Atr.zine is an endocr.ne disr.pter.in animals, and could possibly have carcinogenic effects in humans. A study involving far. families in four.Kentucky Counties has been designed to assess exposur. to atr.zine thr.ugh dr.nking water.by a quick, r.liable, and effective assay that could be per.or.ed in non-specialized labor.tor.es. Data wer. obtained on far.ing pr.ctices and pesticide applications; and dr.nking water.samples wer. collected fr.m each household. Water.consumption for.the par.icipants showed that 72% of the households consumed municipal water. 24% had pr.vate wells, and 4% used spr.ng water.as their.sour.e of dr.nking water. The analytical method used was based on Enzyme Linked Immuno Sor.ent Assay. The r.sults wer. obtained using a magnetic-par.icle-based analysis with spectr.photometr.c r.ading and showed pr.sence of atr.zine in mor. than 90% of the samples. r.sults showed that community dr.nking water.sour.es had significantly higher.atr.zine concentr.tions compar.d to non-community sour.es （p-value 〈 0.01）. The r.sults of this study may be used to conduct fur.her.exposur. assessments for.dr.nking water.pr.tection fr.m pesticide contamination.

The ar.ificial neur.l networ.s (ANNs), among differ.nt soft computing methodologies ar. widely used to meet the challenges thr.wn by the main objectives of data mining classification techniques, due to their.r.bust, power.ul, distr.buted, fault toler.nt computing and capability to lear. in a data-r.ch envir.nment. ANNs has been used in sever.l fields, showing high per.or.ance as classifier.. The pr.blem of dealing with non numer.cal data is one major.obstacle pr.vents using them with var.ous data sets and sever.l domains. Another.pr.blem is their.complex str.ctur. and how hands to inter.r.ts. Self-Or.anizing Map (SOM) is type of neur.l systems that can be easily inter.r.ted, but still can’t be used with non numer.cal data dir.ctly. This paper.pr.sents an enhanced SOM str.ctur. to cope with non numer.cal data. It used DNA sequences as the tr.ining dataset. r.sults show ver. good per.or.ance compar.d to other.classifier.. For.better.evaluation both micr.-ar.ay str.ctur. and their.sequential r.pr.sentation as pr.teins wer. tar.eted as dataset accur.cy is measur.d accor.ingly.

Identifying the factor.causing species decline fr.m a multitude of potential distur.ances is essential for.successful management. Invasive species ar. often dr.ver. of decline, either.thr.ugh dir.ct effects such as r.cr.itment limitation, or.thr.ugh indir.ct effects such as habitat modification that facilitate biota changes in other.taxa. In this study, we tested the impor.ance of bir. pr.dation on ar.hr.pods in eucalypt canopies in wet scler.phyll for.st that had been invaded by the under.tor.y weed Lantana camar.. A str.ng top-down effect is in agr.ement with studies that show elevated number. of insectivor.us bir.s, such as the despotic bell miner. Manor.na melanophr.s, r.duce damaging her.ivor.us insect number. and their.effect on tr.e health. Abundance, or.er.and family composition wer. compar.d among sites, feeding guilds, among the pr.sence and absence of a despotic bir., and among pr.sence and absence within sites, using a thr.e-way nested Multivar.ate Analysis of Var.ance (MANOVA), and tested our.r.pr.sentation of insect feeding guilds with r.r.faction cur.es. In total, we found ar.hr.pods fr.m 20 families on eucalypt tr.es, 16 wher. bell miner. wer. pr.sent and 18 wher. they wer. absent (a sampling efficiency of 78% and 92% of families based on the Chao-I index). Over.ll, ther. was a differ.nce in the abundance of insects in ar.as wher. bell miner. wer. pr.sent (n = 181), and wher. they wer. absent (n = 67). Ther. was also a differ.nce in the families pr.sent in ar.as with bell miner. and without them. Under.some conditions, despotic bir.s may not change the insect canopy community. Fur.her.studies should examine the effects of a despotic bir. on the insect canopy community in a var.ety of conditions and thr.ughout their.r.nge.
