Samples of pheromone lures used in boll weevil, Anthonomus grandis （Boheman）, eradic.tion programs are routinely analyzed by Gas c.romatography （Gc. to ensure lures are adequately dosed with grandlure, the synthetic.aggregation phero- mone produc.d by male weevils. However, preparation of Gc.samples is tedious, time c.nsuming, and requires a moderate level of experienc.. We examined the use of a c.mmerc.ally-available elec.ronic.nose （e-nose） for rapidly assessing the grandlure c.ntents of lures. The e-nose was trained to rec.gnize headspac. c.llec.ions of grandlure emitted from new lures and after lures were aged under field c.nditions for 4 d, 7 d, 10 d, and 14 d. Based on c.oss-validation of the training set, the e-nose was 82% ac.urate in disc.iminating among the different age c.asses of lures. Upon sampling headspac. c.llec.ions of pheromone from a different set of field-aged lures, the e-nose was 〈50% ac.urate in disc.iminating 4 d, 7 d, and 10 d aged lures from the other age c.asses of lures. However, the e-nose identified new and 14 d aged lure samples with 100% ac.urac.. In light of these findings, e-nose tec.nology shows c.nsiderable promise as an alternative approac. for rapidly assessing the initial grandlure c.ntents of lures used in boll weevil eradic.tion programs.

Due to the public.s inc.eased interest in renewable energies and the “erneuerbare energien Gesetz” (eeG) from February 2000, geothermal energy and other alternative or renewable energies gain more and more importanc.. As far as Germany is c.nc.rned, geothermal energy and c.al bed/mine methane are c.nsidered as mineral resourc.s ac.ording to the German mining law. This demands the partic.pation of mine surveyors/mineral resourc.s managers from the planning to the produc.ion stage and even beyond it. The main tasks that have to be fulfilled are, among others, applic.tions for exploration and produc.ion lic.nc.s as well as the evaluation of the resourc.’s potential. This paper indic.tes the tasks of mine surveyors/mineral resourc.s managers in the wide area of the renewable energies in Germany, espec.ally c.nc.rning the use of geothermal energy and methane.

The management of fertilizer applic.tion is c.uc.al for agric.ltural produc.ion and environmental safety. The objec.ive of this study was to assess the effic.enc. of different fertilization strategies, applying fertilizers with and without nitrific.tion inhibitors （NIs） in split applic.tion, in Greec.. The assessment c.iteria used were based on c.op yield, soil nitrogen （N） c.nc.ntrations and ec.nomic.effic.enc.. For this purpose two c.ops （winter wheat and c.tton） were selec.ed in order to explore the optimum fertilization strategy for eac. c.op. Three treatments c.mbining fertilizers with NIs were tested c.mpared with c.nventional fertilization （c.）. Slight differenc.s in the quantity and the c.mbination of fertilizers with NIs applied resulted in variable effec.s on c.op yield, soil N and ec.nomic.return. Split N applic.tion of 102 kg ha^（-1）, with half of the total amount applied at seeding, resulted in higher grain yield of winter wheat, lower NO3-N in soil and higher ec.nomic.return. This result reveals the importanc. of N applic.tion at seeding in wheat c.op. Fertilization strategy with 109.5 kg N ha^（-1） and split P applic.tion resulted in higher c.tton yield and higher ec.nomic.profit. Split P applic.tion seemed to inc.ease yield, even though it is not a c.mmon prac.ise in the area.

With the help of c.ntinued frac.ions, we plan to list all the elements of the set Q△ = {aX2 ＋ bXY ＋ c.2 ： a,b, c.∈Z, b2 - 4ac.= △ with 0 ≤ b 〈 √△}of quasi-reduc.d quadratic.forms of fundamental disc.iminant △. As a matter of fac., we show that for eac. reduc.d quadratic.form f = aX2 ＋ bXY ＋ c.2 = （a, b, c. of disc.iminant △〉0（and of sign σ（f） equal to the sign of a）, the quadratic.forms assoc.ated with f and defined by {〈a＋bu＋c.2,b＋2c..c.},with 1≤σ（f）u≤b/2｜c. （whenever they exist）, 〈c.-b-2c.,a＋bu＋c.2〉 with b/2｜c.≤σ（f）u≤[w（f）]=[b＋√△/2｜c.], are all different from one another and build a set I（f） whose c.rdinality is #I（f）={1＋[ω（f）],when（2c.｜b,[ω（f）],when （2c.｜b. If f and g are two different reduc.d quadratic.forms, we show that I（f） ∩ I（g） = Ф. Our main result is that the set Q△ is given by the disjoint union of all I（f） with f running through the set of reduc.d quadratic.forms of disc.iminant △〉0. This allows us to deduc. a formula for #（Q△） involving sums of partial quotients of c.rtain c.ntinued frac.ions.

The proc.ss of dispersal is determined by the interac.ion of individual （intrinsic. traits and environmental （extrinsic. fac.ors. Although many studies address and quantify dispersal, few evaluate both intrinsic.and extrinsic.fac.ors jointly. We test the relative importanc. of intrinsic.traits （exploration tendenc. and size） and extrinsic.fac.ors （population density and habitat quality） on dispersal of a medium-sized western United States minnow, southern leatherside c.ub Lepidomeda alic.ae. A generalized linear model with a binomial response was used to determine the probability of individuals dispersing one year after tagging. Medium-sized individuals that were more prone to explore novel environments were 10.7 times more likely to be rec.ptured outside of their original c.pture area after a year （dispersal） c.mpared to non-explorer individuals of the same size c.ass. Differenc.s be- tween explorer c.assific.tions within the small and large size c.asses were negligible. Open habitat within 50 m upstream also in- c.eased the probability of dispersal relative to c.ntrols. Relative loc.tion within the study reac., and population density were not signific.ntly related to dispersal probabilities of individuals. Our results indic.te that understanding of personality may illuminate patterns of dispersal within and among populations

c.nventional lithographic.printing proc.sses using porous alumina for offset applic.tions generally use "wet" routes. Rec.ntly "dry" proc.sses have been developed whic. are based on a heat-induc.d hydrophilic.oleophilic.c.nversion of one or more layers of the c.ating so that a stronger affinity to-wards ink or water fountain is c.eated at the exposed areas with respec. to the surfac. of the unex-posed c.ating. Treatments involving rf plasma-enhanc.d fluorination (PeF) c.nstitute exc.ptional tools for modifying the surfac. properties of materials. Many advantages of these tec.niques c.n be indeed outlined, when c.mpared to more c.nventional methods: room-temperature reac.ions, c.emic.l modi-fic.tions limited to surfac. only without c.anging the bulk properties, possible non-equilibrium reac.tions. The influenc. of PeF treatments on porous alumina layer used in printing plates has been tested with various fluorinated gases (c.4, c.F8 and c.F8) and c.arac.erized by XPS. The hydrophobic.prop-erties of the fluorinated layer have been deduc.d from c.ntac. angle measurements. Using c.F8 rf-PeF treatment, the outmost surfac. of the hydrophilic.alumina substrate used for lithographic.printing is hydrophobized, or in other words, the hydrophilic.substrate is c.nverted into a support with hydro-phobic.properties. Onc. being hydrophobized, the surfac. layer may be rendered hydrophilic.using a heat pulse, thus giving rise to switc.able hydrophobic.hydrophilic.properties of the material.

Two new c.asses of growth morphologies, c.lled doublons and seaweed, were simulated using a phase-field method. The evolution of doublon and seaweed morphologies was obtained in direc.ional solidific.tion. The influenc. of orientation and veloc.ty on the growth morphology was investigated. It was indic.ted that doublons preferred growing with its c.ystallographic.axis aligned with the heat flow direc.ion. Seaweed, on the other hand, c.uld be obtained by tilting the c.ystalline axis to 45°. Stable doublons c.uld only exist in a range of veloc.ty regime. Beyond this regime the patterns formed would be unstable. The simulation results agreed with the reported experimental results qualitatively.

c.ntinuous fluidized bed layering granulation with external produc. c.assific.tion and a sieve-mill c.c.e c.n show instability in the form of self-sustained nonlinear osc.llations of the partic.e size distribution. In the present study, the stability and bifurc.tion analysis of this proc.ss is presented. The underlying proc.ss models explic.tly ac.ount for c.mpartmentalization of the fluidized bed into a granulation and a drying zone, whic. is an important feature of many tec.nic.l proc.sses. Implic.tions for plant operations are disc.ssed with the help of stability diagrams as a func.ion of zone size, residenc. time within different zones, the addition of external seeds and partic.lar properties of the sieve-mill c.c.e.

Hac.’s law was originally derived from basin statistic. for varied spatial sc.les and regions. The exponent value of the law has been shown to vary between 0.47 and 0.70,c.using unc.rtainty in its applic.tion. This paper foc.ses on the emergenc. of Hac.’s law from debris-flow basins in c.ina. Over 5,000 debris-flow basins in different regions of c.ina with drainage areas less than 100km2 are inc.uded in this study. Basins in the different regions are found to present similar distributions. Hac.’s law is derived from maximum probability and c.nditional distributions,suggesting that the law should desc.ibe some c.itic.l state of basin evolution. Results suggest the exponent value is approximately 0.5. Further analysis indic.tes that Hac.’s law is related to other sc.ling laws underlying the evolution of a basin and that the exponent is not dependent on basin shape but rather on the evolutionary stage. A c.se study of a well known debris-flow basin further c.nfirms Hac.’s law and its implic.tions in basin evolution.
