The petrographic com.osition of Cretaceou.-age coals hosted in the Benu. Trou.h,Nigeria is presented and discu.sed in term. of the paleodepositional settings that infu.nced the coal-bearing *** Benu. Trou.h is a failed arm.of the triple ju.ction of an inland sedim.ntary basin that extends in a NE-SW direction from.the Gu.f of Gu.nea in the sou.h,to the Chad Basin in the north.A total of twenty-nine(29)coal sam.les were obtained from.nineteen coal localities in the u.per(u.T),m.ddle(m.T),and Lower Benu. Trou.h(LBT).The high average volatile m.tter yield,low average ash yield,high calorifc valu.(24.82 m./kg,on average),and low su.phu. valu.s indicate good qu.lity coal *** organic m.tter is dom.nated by vitrinite,reported at an average of 59.3%by volu.0}(m.neral-m.tter free).Variation was noted in the inertinite content across three *** m.cerals were not com.only observed in the stu.ied sam.les and were absent in the m.T *** facies stu.ies decipher the paleoenvironm.ntal conditions u.der which the vegetation *** com.only u.ed are the gelifcation index(GI),tissu. preservation index(TPI),grou.d water index(GWI and variations),vegetation index(VI),and wood index(WI).Com.aring the array of coal facies m.dels applied,the m.T sam.les difer from.the u.T and LBT sam.les,concu.ring with the coal qu.lity *** u.T and LBT coals form.d in an u.per deltaic to drier piedm.nt plane depositional environm.nt,while the m.T coal form.d in a lower deltaic m.rsh to wet forest swam. depositional *** sam.les indicate an om.rotrophic *** view of the m.difed equ.tions and the plots u.ed,interpreting depositional environm.nts from.ju.t a single m.del is not reliable.

Arg., Swietenia m.crophylla King. and Tectona grandis L. were collected from.different locations of m.dhu.u. forest area to stu.y the biodiversity of Arbu.cu.ar m.corrhizal （Am. fu.gal colonization and spore popu.ation. All the plants showed Am.colonization. Ou. of eight selected plants, m.celial colonization was lowest in the roots of A. heterophyllu. （22%） and the highest was in the roots of H. brasiliensis （78%）. m.celial intensity was observed poor （25%-77%） and m.derate （23%-57%） in all plants species and abu.dant （11%-40%） was in m.st of the plant species. Vesicu.ar colonization was observed in five plant species. The lowest was recorded in E. cam.ldu.ensis （4%） and the highest was in H. brasiliensis （21%）. Poor （24%-56%）, m.derate （16%-100%） and abu.dant （11%-40%） type of vesicu.ar intensity were observed. Arbu.cu.ar colonization was observed in three plants. The highest was in A. m.ngiu.0}（72%） and the lowest was in S. m.crophylla （17%）. Arbu.cu.ar intensity was recorded as poor （12%-44%）, m.derate （22%-100%） and abu.dant （4%-47%）. The highest Am.fu.gal spore popu.ation was in A. au.icu.iform.s （714） and the lowest was in D. sissoo （102）. Five Am.fu.gal genera were recorded. Glom.s was fou.d to be dom.nant. A few spores rem.ined u.identified. Significant correlation was observed between percent coloniza- tion and spore popu.ation. The resu.ts of the present stu.y indicate the occu.rence of Am.fu.gi and the m.cotrophism.of the plants of m.dhu.u. forest area and the applicability of Am.technology in the forest m.nagem.nt of m.dhu.u. forest.

ISBN: (纸本)3540726128

Field-Program.able Gate Arrays (FPGAs) are revolu.ionizing digital signal processing as novel FPGA fam.lies are replacing ASICs and PDSPs for front-end digital signal processing algorithm.. So the efficient im.lem.ntation of these algorithm. is critical and is the m.in goal of this book. It starts with an overview of today's FPGA technology, devices, and tools for designing state-of-the-art DSP system.. A case stu.y in the first chapter is the basis for m.re than 40 design exam.les throu.hou.. The following chapters deal with com.u.er arithm.tic concepts, theory and the im.lem.ntation of FIR and IIR filters, m.ltirate digital signal processing system., DFT and FFT algorithm., advanced algorithm. with high fu.u.e potential, and adaptive filters. Each chapter contains exercises. The VERILOG sou.ce code and a glossary are given in the appendices, while the accom.anying CD-ROm.contains the exam.les in VHDL and Verilog code as well as the newest Altera "Qu.rtu. II web edition" software. This edition has a new chapter on m.croprocessors, new sections on special fu.ctions u.ing m.C calls, intellectu.l property core design and arbitrary sam.ling rate converters, and over 100 new exercises.

Annihilation of Antiprotons in Light Nu.lei

作者： m. A. Rana E. u. Khan m. I. Shahzad I. E. Qu.eshi F. m.lik G. Sher S. m.nzoor H. A. Khan Physics Research Division PINSTECH P. O. Nilore Islamabad Pakistan

CR-39 detectors have been exposed to a 5.9-m.V antiproton beam.u.ing the low energy antiproton ring （LEAR） facility at CERN. At this energy, tracks of antiprotons appear in a CR-39 detector after 135 rain of etching in 6m.NaOH at 70℃. Flu.nce of the antiproton beam.has been determ.ned u.ing track density. We have also fou.d tracks in the etched CR-39 detector at different depths （250-500μm.. These tracks have resu.ted from.the annihilation of antiprotons with the constitu.nts （H, C and O） of the CR-39 detector. The goal of the experim.nt is to develop a sim.le and low-cost m.thod to stu.y properties of antiparticles and those form.d after annihilation of these particles with the target m.tter.

作者： N. Ali E. u. Khan K. Khan DPAm PLEAS P.O. Nilore Islamabad Pakistan P.D PINSTECH P.O. Nilore Islamabad Pakistan Departm.nt of Physics CIIT Islamabad Pakistan HPD PINSTECH P.O. Nilore Islamabad Pakistan

Six different solu.ions of 6m.NaOH, containing different am.u.ts of Na2CO3 at 70℃ were u.ed for the revelation of latent dam.ge trails in CR-39 plastic track detectors. These detectors were earlier exposed to fission fragm.nts from.^252 Cf sou.ce for 30 m.n in vacu.m.and were then etched in the respective solu.ions for different etching tim. intervals of 5-20 m.n starting from.5m.n u. to 160m.n. The etch indu.tion tim. in each detector was obtained by extrapolating the intersection of resu.ting cu.ves of track lengths and track diam.ters with the tim. axis.

We stu.y the real Bonnet su.faces which accept one u.iqu. nontrivial isom.try that preserves the m.an cu.vatu.e, in the three-dim.nsional Eu.lidean space. We give a general criterion for these su.faces and u.e it to determ.ne the tangential developable su.faces of this kind. They are determ.ned im.licitly by elliptic integrals of the third kind. Only the tangential developable su.faces of circu.ar helices are explicit exam.les for which we com.letely determ.ne the above u.iqu. nontrivial isom.try.

The high field electrical condu.tion m.chanism.for the widely u.ed ZnS thin film. in the m.croelectronic indu.try is investigated. Experim.ntal data on the dc condu.tion as a fu.ction of the applied bias for the A1-ZnS-A1 devices is carefu.ly com.ared with the theoretical equ.tions given by Schottky and Poole-Freu.el. The resu.ts yield the valu. of the coefficient of the barrier lowering com.atible with the Schottky theory rather than the Poole-Frenkel theory, which are also in agreem.nt with the resu.ts reported earlier by m.ekawa [Phys. Rev. Lett. 24 （1970） 1175]
