Phos.horus.P) deficiency.in s.il is.a m.jor cons.rain for rice production. An im.ortant s.t of rice genoty.es.landraces. old im.roved and new im.roved varieties. were s.reened for P deficiency.tolerance in two m.jor cropping s.as.ns.of s.i Lanka, in 2012. The Ultis.l s.il, which was.collected from.a plot cultivated with rice without fertilizer application for pas. 40 y.ars.P_0) at the Rice Res.arch and Developm.nt Ins.itute(RRDI), Bathalagoda, s.i Lanka, was.us.d as.the potting m.dium.for greenhous. trials. Two field trials.were conducted in the s.m. plots.at RRDI. Both P_0 and P_(30)(30 m./kg P_2O_5) conditions.were us.d in the two greenhous. trials. At the early.vegetative(three weeks.after trans.lanting), late vegetative(s.x weeks.after trans.lanting) and flowering s.ages. plant height and num.er of tillers.per plant were recorded. At the flowering s.age, s.oots.were harves.ed and s.oot dry.weight, s.oot P concentration, s.oot P uptake and P utilization efficiency.were m.as.red. All data were s.atis.ically.analy.ed us.ng analy.is.of variance, regres.ion and clus.er procedures. The m.as.red param.ters.were s.gnificantly.different between P_0 and P_(30) conditions.P s.oot dry.weight was.reported by.the rice genoty.es.H4 and m.rs. under P_0 conditions. The regres.ion analy.is.between s.oot dry.weight and P utilization efficiency.revealed that the s.udied rice genoty.es.could be categorized to three P deficiency.tolerance clas.es. A total of 13 genoty.es.could be cons.dered as.highly.tolerant and 4 genoty.es.as.s.ns.tive for P deficiency. Thes. res.lts.could be us.d to s.lect parental genoty.es.for breeding and genetic s.udies.and als. to s.lect interes.ing varieties.or landraces.for organic rice production.

The inves.igation of runaway.electrons.is.expanded by.different m.thods. The aim.of this.s.udy.is.to s.ow s.wtooth os.illations.of hard x-ray.em.s.ion and with the help of s.wtooth os.illations.to obtain radial diffus.on coefficient and m.gnetic fluctuations. In the s.m. way. the hard x-ray.s.ectral evaluation is.com.ared in s.veral tim. intervals.and it is.s.own that during dis.harge, the energy.of the runaway.electrons.is.les. than 200？keV. Als., for ty.ical plas.as. population of runaway.electrons.is.m.as.red at s.ven tim. intervals.of 5m.0}and tem.oral evaluation of runaway.electron m.an energy. The s.wtooth-like s.ape is.obs.rved in the hard x-ray.range （10–1000？keV）. By.the s.wtooth os.illation m.thod, the RE diffus.on coefficient in radial trans.ort in the IR-T1 plas.a is.Dr～0.5Dr～0.5m.2s.-1. The m.gnetic field fluctuation due to m.gnetic diffus.on Dm.m.is.given as.br/Bt～10^-4.

Frontiers.of s.ructural and Civil Engineering 2019年第4期13卷 998-1006页

作者： Atheer H. m. ALGBURI m. neaz s.EIKH m.ham.ad n. s. HADI s.hool of Civil Mining and Environmental Engineering University of Wollongong NSW 2522 Australia

This.s.udy.exam.nes.the properties.of fiber-reinforced reactive powder concrete (FR-RPC). s.eel fibers. glas. fibers. and s.eel-glas. hy.rid fibers.were us.d to prepare the FR-RPC. The non-fibrous.reactive powder concrete (nF-RPC) was.prepared as.a reference m.x. The proportion of fibers.by.volum. for all FR-RPC m.xes.was.1.5%. s.eel fibers.of 13 m. length and 0.2 m. diam.ter were us.d to prepare the s.eel fiber-reinforced RPC (s.R-RPC). Glas. fibers.of 13 m. length and 1.3 m. diam.ter were us.d to prepare the glas. fiber-reinforced RPC (GFR-RPC). The hy.rid fiber-reinforced RPC (HFR-RPC) was.prepared by.m.xing 0.9% s.eel fibers.and 0.6% glas. fibers. Com.res.ive s.rength, axial load-axial deform.tion behavior, m.dulus.of elas.icity. indirect tens.le s.rength, and s.ear s.rength of the RPC m.xes.were inves.igated. The res.lts.s.owed that s.R-RPC achieved higher com.res.ive s.rength, indirect tens.le s.rength and s.ear s.rength than nF-RPC, GFR-RPC, and HFR-RPC. Although the com.res.ive s.rengths.of GFR-RPC and HFR-RPC were s.ightly.lower than the com.res.ive s.rength of nF-RPC, the s.ear s.rengths.of GFR-RPC and HFR-RPC were higher than that of nF-RPC.
