Recall the notion due to W. Browder of a Poincaré embedding [Br1, Br3, Br2, Br4, Wa, Ra, Wi1, Wi2], which is the homotopy analogue of a smooth embedding of manifolds. Let (M,A) be a simply connected m-dimensional (finite) Poincaré pair. A Poincaré embedding of (M,A) in the sphere S will mean a finite CW-complex W and a map f : A −→ W , such that the homotopy pushout M ∪ι A× [0, 1] ∪f W is homot...

Five low-lying (Te < 2200 cm ) electronic states of NiI have been observed using single vibronic level (SVL) emission spectroscopy, via three hitherto unobserved band systems in the range 21 150– 22 410 cm . In addition to the previously characterized XD5/2 and A P3=2 states, the X D3=2, A P1=2, and BR1=2 states have been observed for the first time. The emission spectra yield term energies and...

Recent subcritical VENUS-F experiments showed that fission chambers with a threshold deposit like U-238 can essentially improve the on-line sub-criticality measurments beam interruption method, which is currently supposed to be main method for ADS MYRRHA. To suppress uncertainty caused by fissions in U-235 impurities, fraction of U should accurately known. Three PHOTONIS CFUL01 type were purcha...

Proper management of brackish water can increase plant production in the Brazilian semi-arid region. The objective this study was to evaluate performance and use efficiency two peanut genotypes irrigated with during reproductive stage, soil without cover. conducted a greenhouse. experimental design used randomized blocks, four replicates, 2 x factorial scheme (two electrical conductivities irri...
