In this article, we study the generalized b.rnoulli learning m.del b.sed on the prob.b.lity of.success pi = ai /n where i = 1,2,...n 0a1a2ann and n is positive integer. This gives the previous results given b. Ab.ulnasser and Khidr [1], Rashad [2] and EL-Desouky and m.hf.uz [3] as special cases, where pi = i/n pi = i2/n2 and pi = ip/np respectively. The prob.b.lity f.nction P(Wn = k) of.this m.del is derived, som. properties of.the m.del are ob.ained and the lim.ting distrib.tion of.the m.del is given.

Three sets of.satellite data were utilized to outline and m.nitor the waterlogging prob.em. along the Wadi El Tum.late b.sin. These data include Them.tic m.pper im.ge f.r year 1984, Enhanced Landsat Them.tic m.pper im.ge f.r year 2000 and SPOT-4 im.ge f.r year 2008. Supervised classif.cation using the m.xim.m.likelihood approach has b.en perf.rm.d. A num.er of.6 classes were ob.erved at the study sites including, Niledeposits and cultivated areas, surf.ce water and water logged areas, salt crust, Quaternary playa deposits, f.uviatile and lacustrine deposits and m.ocene (gypsum.and carb.nate) deposits. Water logged areas expanded f.om..1 km. inyear 1984 to18.8 km. inyear 2000 to25.3 km. inyear 2008, with a rate of..7 km./year. At the sam. tim., vegetation cover shows an increase f.om.53 km. inyear 1984 to719 km. inyear 2008. The integrated data used b. Geographic Inf.rm.tion System. specif.ed f.ctors controlling waterlogging prob.em., which are: topography, drainage pattern and water f.ow direction, excess of.irrigation water, def.ciency of.drainage system. presence of.im.erm.ab.e clay lenses and lineam.nts direction. Groundwater m.deling including Gm. and m.Df.OW program. were processed to m.nage waterlogging prob.em. Using of.underground tile drain along the eastern portion of.Wadi El Tum.late b.sin and dewatering wells along the western side was recom.ended to ob.ain the highest m.netary return f.om.the drainage investm.nt.

The deb.is was f.und to b. produced at a rate of.1.55 kg per person per day f.r a total of.5177 tons per m.nth. The com.osition report showed 75% m.terial reusab.e f.r construction purposes, 15% m.terial recyclab.e through reverse logistics and 10% ref.se to b. disposed of.at landf.lls. The study developed legal and m.nagerial instrum.nts that stim.late private operators to achieve landf.ll diversions in the order of.90% of.this waste. The argum.nts were supported b. a f.ow diagram.that indicates the correct destination of.all waste item. and an econom.c b.lance of.private waste m.vem.nt.

The prediction of.the lam.nar to turb.lent transition is essential in the calculation of.turb.ne b.ades, com.ressor b.ades or airf.ils of.airplanes since a non negligib.e part of.the f.ow f.eld is lam.nar or transitional. In this paper we com.are the prediction capab.lity of.the Detached Eddy Sim.lation （DES） with the Large Eddy Sim.lation （LES） using the high-pass f.ltered （HPf. Sm.gorinsky m.del （Stolz et al.[1]） when applied to the calculation of.transitional f.ows on turb.ne b.ades. Detailed m.asurem.nts f.om.Canepa et al.[2] of.the well known VKI-turb.ne b.ade served to com.are our results with the experim.nts. The calculations have b.en m.de on a f.action of.the b.ade （10%） using non-ref.ective b.undary conditions of.f.eund at the inlet and outlet plane extended to internal f.ows b. m.gagnato et al.[3] in com.ination with the Synthetic Eddy m.thod （SEm. proposed b.

It has b.en repeatedly shown that hyb.id approaches can satisf.ctorily predict f.ows of.engineering relevance.

The superplasticity and dif.usion b.nding of.IN718 superalloy were studied in this article. The strain rate sensitivity index m.was ob.ained at dif.erent tem.eratures and various initial strain rates using the tensile speed m.tation m.thod; m.reached its m.xim.m.value 0.53 at an initial strain rate of.1×10^-4s^-1 at 1253K. The dif.usion b.nding param.ters, including the b.nding tem.erature T, pressure p, and tim. t, af.ected the m.chanism.of.joints. When the b.nded specim.n with 25μm.thick nickel f.il interlayer was tensile at room.tem.erature, the shear f.acture of.the joints with nickel f.il interlayer took place at the IN718 part. m.crostructure study was carried out with the b.nded sam.les. The m.crostructure shows an excellent b.nding at the interf.ces. The optim.m.param.ters f.r the dif.usion b.nding are： T = 1273-1323K, p = 20-30m.a, t = 45-60m.n.

61 varieties of.wheat collected in the gene f.nd of.the Research Institute of.Crop Husb.ndry were screened using SCAR-m.rkers associated with the gene of.resistance to b.own leaf.rust, Lr19. As a result of.PCR analysis using SCS123 m.rker the 737 b. locus was detected in 48 genotypes. The expected f.agm.nt of.the 688 b. was detected in 53 genotypes using the SCS253 m.rker. The results ob.ained using b.th m.rkers indicate that the Lr19 gene is present on 7D chrom.som.s of.45 genotypes. The existence of.the Lr19 gene has not b.en proven only f.r 5 f.om.the 61 analyzed wheat genotypes.
