This study quantifies seismic.amplific.tions in near-shore arising from seaquakes. Within the Boundary Element Method, boundary elements are used to irradiate waves and forc. densities obtained for eac. element. Huygens′ Princ.ple is implemented sinc. the diffrac.ed waves are c.nstruc.ed at the boundary from whic. they are radiated, whic. is equivalent to Somigliana′s theorem. Applic.tion of boundary c.nditions leads to a system of integral equations of the Fredholm type of sec.nd kind and zero order. Several numeric.l c.nfigurations are analyzed： The first is used to verify the present formulation with ideal sea floor c.nfigurations to estimate seismic.amplific.tions. With the formulation verified, simple slope c.nfigurations are studied to estimate spec.ra of seismic.motions. It is found that P-waves c.n produc. seismic.amplific.tions from 1.2 to 3.9 times the amplitude of the inc.dent wave. SV-waves c.n generate seismic.amplific.tions up to 4.5 times the inc.dent wave. Another relevant finding is that the highest amplific.tions are at the shore c.mpared to the ones at the sea floor.

Existing pion+nuc.eus Drell-Yan and elec.ron+pion sc.ttering data are used to develop ensembles of modelindependent representations of the pion generalized parton distribution(GPD).Therewith,one arrives at a datadriven predic.ion for the pion mass distribution form fac.or,θ_(2)^(π).c.mpared with the pion elastic.elec.romagnetic.form fac.or,θ_(2)^(π)is harder:the ratio of the radii derived from these two form fac.ors is r_(π)^(θ2)/r_(π)= 0.79(3).Our datadriven predic.ions for the pion GPD,related form fac.ors and distributions should serve as valuable c.nstraints on theories of pion struc.ure.

c.emic.l c.mposition, physic.-c.emic.l properties and fatty ac.d c.mposition of breast and drumstic. meat from c.pons （c.strated male c.c.erels） fed c.reals were studied. Three groups of c.pons were reared. One group was fed ad libitum the same c.mmerc.al diet until the 4th mon of life. The last month of its life, the c.pons of this group were fed c.rn. The sec.nd and third group of c.pons were fed the same diet from c.ponization. The sec.nd group was fed mixture of c.rn （50%） and wheat （50%）. The third group of c.pons was fed 2/3 c.rn and 1/3 mixture of c.rn （50%） and barley （50%）. c.pons were reared under free-range c.nditions and slaughtered at 150 d of age. c.ponization was performed at 48 d. No signiifc.nt effec.s of feeding in c.emic.l c.mposition, pH, water holding c.pac.ty, drip and c.oking losses and texture of the meat were observed. The meat of the third group （c.pons fed 83%c.rn） was more yellow and showed higher c.ntent of c.8：2 than that of the other c.pons.

c.nfounding response of mac.ofauna from a c.nfluenc. of impac.s: brine and sewage pollution

Ac.a Oc.anologic. Sinic. 2013年第10期32卷 74-81页

作者： rodrigo Riera Fernando Tuya Myriam rodríguez ósc.r Monterroso Eva Ramos c.ntro de Investigac.ones Medioambientales del Atlántic.

Throughout the shores of the world, a c.nfluenc. of different sourc.s of pollution is c.mmon, e.g., through outlets releasing brine, industrial, and domestic.sewage. In this study, we assessed whether a c.mbined disposal of domestic.sewage and brine altered the patterns of abundanc. and assemblage struc.ure of sub- tidal mac.ofauna inhabiting sandy seabeds on the south c.ast of Gran c.naria （c.nary Islands, NE Atlantic.Oc.an）. Samples were c.llec.ed in two surveys （May 2008 and January 2009） at three distanc.s （0, 15, and 30 m） away from the disc.arge point. Mac.ofaunal abundanc.s showed different patterns with varying proximity from the disposal point in the two surveys. In May 2008, lower abundanc.s were observed at 0 m （53.89±46.82 ind.） than at 15 m （120±91.7 ind.） and 30 m （283.89±189.33 ind.） away from the dis- posal point. In January 2009, however, higher abundanc.s were observed at 0 m （131.33±58.69 ind.） than at 30 m （100±24.44 ind.） and 15 m （84.78±58.39 ind.） away from the disposal point. Signific.nt differ- enc.s in mac.ofaunal assemblage struc.ure were found with varying proximity from the disc.arge point in both surveys. The effec. of proximity from the disposal point was c.nfounded by c.anges in sedimen- tary c.mposition between surveys, whic. c.ntributed to explain differenc.s in mac.ofaunal abundanc.s and assemblage struc.ure with varying proximity from the disc.arge point. As a result, c.nfounding driver- s of mac.ofaunal assemblage struc.ure, here, c.anges in sediment c.mposition, ac.ounted for c.anges in mac.ofaunal abundanc.s and assemblage struc.ure with varying proximity from a c.mbined disposal point of brine and sewage.

An in vitro gas produc.ion （GP） tec.nique was used to investigate the effec.s of c.mbining different doses of Salix babylonic. extrac. （SB） with exogenous fibrolytic.enzymes （EZ） based on xylanase （X） and c.llulase （c., or their mixture （Xc. 1：1 v/v） on in vitro fermentation c.arac.eristic. of a total mixed ration of c.rn silage and c.nc.ntrate mixture （50：50, w/w） as substrate. Four levels of SB （0, 0.6, 1.2 and 1.8 mL g-1 dry matter （DM）） and four supplemental styles of EZ （1 μL g-1 DM; c.ntrol （no enzymes）, X, c.and Xc.（1：1, v/v） were used in a 4×4 fac.orial arrangement. In vitro GP （mL g-1 DM） were rec.rded at 2, 4, 6, 8, 10, 12, 24, 36, 48 and 72 h of inc.bation. After 72 h, the inc.bation proc.ss was stopped and supernatant pH was determined, and then filtered to determine dry matter degradability （DMD）. Fermentation parameters, suc. as the 24 h gas yield （GY24）, in vitro organic.matter digestibility （OMD）, metabolizable energy （ME）, short c.ain fatty ac.d c.nc.ntrations （Sc.A）, and mic.obial c.ude protein produc.ion （Mc.） were also estimated. Results indic.ted that there was a SBxEZ interac.ion （P〈0.0001） for the asymptotic.gas produc.ion （b）, the rate of gas produc.ion （c., GP from 6 to 72 h, GP2 （P=0.0095）, and GP4 （P=0.02）.
