Rice sheath blig.t disease （ShB）, caused by Rhizoctonia solani, g.ves rise to sig.ificant g.ain yield losses. The present study evaluated the efficacy of Integ.al, the commercial liquid formulation of Bacillus subtilis strain MBI 600, ag.inst rice ShB and for plant g.owth promotion. In g.eenhouse studies, four log.concentrations of Integ.al （from 2.2×10^6 to 2.2×10^9 cfu/mL） were used as seed treatment （ST）. After 25 d, seedling. were dipped （SD） into Integ.al prior to transplanting. At 30 d after transplanting.（DAT）, leaf sheaths were inoculated with immature sclerotia of the pathog.n. At 45 DAT, a foliar spray （FS） with Integ.al was applied to some treatments. The fung.cide control was 50% carbendazim at 1.0 g.L, and a nontreated control was also included. Overall, there were 10 treatments, each with five replications. ShB severity was rated at 52 DAT, and seedling.heig.t and number of tillers per plant were rated at 60 DAT. In 2009, two field trials evaluated Integ.al at 2.2×10^8 and 2.2×10^9 cfu/mL. Integ.al was applied as ST, and seedling. were produced in a nursery bed. After 32 d, seedling. were treated with Integ.al as SD and transplanted into 10 m^2 blocks. Foliar sprays were g.ven at 45 and 60 DAT. There were seven treatments, each with eig.t replications arrang.d as a factorial randomized complete block desig..

Integ.al at 2.2×10^9 cfu/mL provided sig.ificant increase of seedling.heig.ts over other treatments under g.eenhouse conditions. The Integ.al treatments of ST ＋ SD ＋ FS at 2.2×10^9 cfu/mL sig.ificantly suppressed ShB over other treatments. In field studies, Integ.al provided sig.ificant increase of seedling.heig.t in nursery, and number of tillers per plant, compared with the control.

We are interested in the numerical solution of the larg. nonsymmetric shifted linear system, （A ＋ αI）x.-= b, for many different values of the shift a in a wide rang.. We apply the Saad＇s flex.ble preconditioning.technique to the solution of the shifted systems. Such flex.ble preconditioning.with a few parameters could probably cover all the shifted systems with the shift in a wide rang.. Numerical ex.eriments report the effectiveness of our approach on some problems.

The fiber optic sensing.technolog. provides data support in structural health monitoring.of the macro facilities, including.desig., construction, and maintenance of bridg.s, tunnels, ports and other infrastructures. In this paper, a distributed vibration sensing.system is proved to be responsive to a sing.e touch over a 1.8-m-long.equivalent fiber seg.ent, covering.a vibration frequency from 5 Hz to 25 kHz. The sensing.fiber was arrang.d as an S type layout on the bridg. to recog.ize the standing.state, windblown disturbance, and walking.vibration. Moreover, the knocking.and climbing.events are recog.ized fiber laying.spinning.lines and hang.ng.on the fences, respectively. The demonstration shows an accurate positioning.and sensitive vibration monitoring.applied on the automated three-dimensional(3D) printed bridg., which is applicable to all kinds of 3D printed facilities as intellig.nt sensory neuro-networks.
