Insect Science 2014年第5期21卷 541-555页

作者： Xinzh. Ni Wenwei Xu mich.el h. blanco W. Paul Williams USDA-ARS Crop Genetics and Breeding Research Unit University of Georgia-Tifton Tifton GA 31793 Agricultural Research.&Extension Center Texas A&M University Lubbock TX 79403 USDA-ARS Plant Introduction Research Unit Iowa State UniversityAmes IA 50011 Corn h.st Plant Resistance Research.Unit USDA-ARS Mississippi State MS 39762 USA

After examining ear-colonizing pest resistance, 20 maize lines from th. USDA- ARS Germplasm Enh.ncement of Maize （GEM） Program were evaluated for wh.rl-feeding fall armyworm （FAW）（Spodopterafrugiperda） resistance using 4 maize inbred lines as th. resistant and susceptible controls. Both.FAW injury ratings at 7- and 14-d after infestation, and predator abundance and diversity at wh.rl stage （V6-V8） were recorded in 2009 and 2010. Th. survey of th. diversity and abundance of predators in each.experimental plot were conducted 7 d after th. FAW infestation. Of th. 20 germplasm lines examined, 3 of th.m （i.e., entries 9, 15, and 19 th.t were derived from tropical maize germplasm lines were originated from Uruguay, Cuba, and Th.iland, respectively） were identified as th. best FAW-resistant germplasm lines using th. leaf injury ratings and predator survey data. In addition, th. abundance and diversity of th. predators were greater in 2010 th.n in 2009, wh.ch.migh. h.ve caused th. low level of th. FAW injury ratings on all lines examined in 2010. Th. 2-year data sh.wed th.t th. FAW injury ratings were negatively correlated to th. predator abundance and diversity, wh.ch.is also influence by genotype × environment interactions. Th. findings suggested th.t tropical germplasm is an important source of native resistance to th. FAW and th. corn earworm. At th. same time, th. maize genotype x environment interaction （e.g., predator attractiveness, and varying weath.r conditions） sh.uld be included in th. multiple-year evaluations of insect and disease resistance of maize germplasm lines under field conditions.

Mineralogy,M-type tetrad effect and radioactivity of altered granites at th. *** Garadi sh.ar zone,central Eastern Desert,Egypt

引用

Ch.nese Journal Of Geoch.mistry 2011年第2期30卷 153-164页

作者： el Nah.s h.A. el Feky M.G. Mira h. Nuclear Materials Auth.rity P.O. Box 530 Cairo Egypt

Th. G. Abu Garadi area is covered mainly by metasediments, alkali feldspar granites and stream sediments. Th. alkali feldspar granite is traversed by a major strike-slip fault trending in an N-S direction as well as two subordinate sets of faults trending NW to WNW for th. first one and NE for th. second one. Th.se faults represent th. sh.ar zones affected by magmatic (syngenetic) as well as h.droth.rmal (epigenetic) activities causing alteration of th. granitic rocks. Th. most common alteration features are albitization, greisenization and koalinitization. Th. mass balance calculations of th. studied altered samples sh.w enrich.ents in Zr, Y, Ni, U, Th.and Ga and depletions in Zn, Sr, Nb, Ba, Pb, Cu and V. Only th. greisenized samples exh.bit a significant enrich.ent in Nb, ∑REE budget and pronounced lanth.nide tetrad effect (M-type), especially TE1,4, wh.le weakly expressed tetrad effects are for th. oth.r albitized and koalinitized samples. Mineralogically, th. common accessory minerals in th. altered samples include samarskite-(Y), betafite, uranoth.rite, zircon, fluorite and cassiterite. Th. greisenized granites contain h.gh.eU and eTh.th.n th. oth.r altered types, wh.re th.y are ch.racterized by an assemblage of th. radioactive minerals; samarskite-(Y), betafite, uranoth.rite in addition to zircon. Th. inter-element relationsh.ps between U and Th.and also th.ir ratios illustrate th.t th. radioelement distribution in th.se granites is mainly governed by magmatic processes, in addition to post-magmatic ones. Th. distribution of ch.mical elements and th. fractionation of some isovalents with.n th. sh.ar zone are largely controlled by th. newly formed mineral ph.ses. With.respect to uranium mobilization, uranium migrated from th. h.st alkali feldspar granites of G. Abu Garadi, wh.le th. sh.ar zones acted as traps for th. migrated uranium. Moreover, U migrated in th. sh.ar zone during greisenization and albitization, and migrated out during koalinitization.

Five new metal-organic frameworks （MOFs） of th. general composition [Ph.SnCu（CN）2.L], wh.re L= pyrazine （pyz）（1）, meth.lpyrazine （mepyz）（2）, 4,4＇-bipyridine （bpy）（3）, trans-l,2-bis（4-pyridyl）eth.ne （tbpe）（4） or 1,2-bis（4-pyridyl）eth.ne （bpe）（5）, h.ve been synth.sized and ch.racterized to test th.ir potential applications as catalysts. Th. structures of th. MOFs 1--5 mainly consist of Cu（CN）2 building blocks connected by th. Ph.Sn cations and th. bipodal ligand forming polymeric networks. Th.y exh.bit strong fluorescence in th. solid state. Also, th.y are used as h.terogeneous catalysts for th. degradation of azo-dyes, metanil yellow （MY） by diluted solution of h.drogen peroxide as oxidant. Th. reaction is first order with.respect to MY dye, wh.le th. factors affecting th. rate constant of th. degradation reaction are investigated. Th. activation parameters of th. reaction h.ve been estimated and a possible mech.nism h.s been proposed.

Th. transport property of a quantum dot under th. influence of external time-dependent field is investigated. Th. mesoscopic device is modelled as semiconductor quantum dot coupled weakly to superconducting leads via asymmetric double tunnel barriers of different h.igh.s. An expression for th. current is deduced by using th. Landauer-Buttiker formula, taking into consideration of both.th. Coulomb blockade effect and th. magnetic field. It is found th.t th. periodic oscillation of th. current with.th. magnetic field is controlled by th. ratio of th. frequency of th. applied ac-field to th. electron cyclotron frequency. Our results sh.w th.t th. present device operates as a radio-frequency single electron transistor.

Four microorganisms, Pseudomonas sp. （ER2）, Aspergillus niger （ER6）, Cladosporium h.rbarum （ER4） and Penicilluim sp. （ER3）, were isolated from cucumber leaves previously treated with.metalaxyl using enrich.ent tech.ique. Th.se isolates were evaluated for detoxification of metalaxyl at th. recommended dose level in aquatic system. Th. effect of ph.and temperature on th. growth.ability of th. tested isolates was also investigated by measuring th. intracellular protein and mycelia dry weigh. for bacterial and fungal isolates, respectively. Moreover, th. toxicity of metalaxyl after 28 d of treatment with.th. tested isolates was evaluated to confirm th. complete removal of any toxic materials （metalaxyl and its metabolites）. Th. results sh.wed th.t th. optimum degree ph.for th. growth.of metalaxyl degrading isolates （bacterial and fungal isolates） was 7. Th. temperature 30℃ appeared to be th. optimum degree for th. growth.of eith.r fungal or bacterial isolates. Th. results sh.wed th.t Pseudomonas sp. （ER2） was th. most effective isolate in metalaxyl degradation followed by Aspergillus niger （ER6）, Cladosporium h.rbarum （ER4） and Penicilluim sp. （ER3）, respectively. Th.re is no toxicity of metalaxyl detected in th. supematant after 28 d of treatment with.Pseudomonas sp. （ER2）. Th. results suggest th.t bioremediation by Pseudomonas sp. （ER2） isolate was considered to be effective meth.d for detoxification of metalaxyl in aqueous media.

Effect of h.gh.Frequency electric Field on Propagation of electrostatic Wave in a Non-Uniform Relativistic Plasma Waveguide

引用

Plasma Science and Tech.ology 2008年第3期10卷 278-283页

作者： Kh.h.el-Sh.RBAGY Plasma Ph.sics and Nuclear Fusion Department Nuclear Research Center Atomic Energy Authority Cairo Egypt

Th. effect of a h.gh.frequency （h.） electric field on th. propagation of electrostatic wave in a 2D non-uniform relativistic plasma waveguide is investigated. A variable separation meth.d is applied to th. two-fluid plasma model. An analytical study of th. reflection of electrostatic wave propagation along a magnetized non-uniform relativistic plasma slab subjected to an intense h. electric field is presented and compared with.th. case of a non relativistic plasma. It is found th.t, wh.n th. frequency of th. incident wave is close to th. relativistic electron plasma frequency, th. plasma is less reflective due to th. presence of both.an h. field and th. effect of relativistic electrons. On th. oth.r h.nd, for a low-frequency incident wave th. reflection coefficient is directly proportional to th. amplitude of th. h. field. Also, it is sh.wn th.t th. relativistic electron plasma leads to a decrease in th. value of reflection coefficient in comparison with.th. case of th. non relativistic plasma.
