and canyon sediments in several canyon reaches are contaminated with low-levels of radionuclides from hisFollowing the May 2000 Cerro Grande fire at Los Alamos, NM, toric LANL operations (Reneau et al., 1998). To mitisurface water control structures were constructed near Los Alamos to mitigate the transport of contaminant-bearing sediment toward the gate potential off-site migration of these se...

Nowadays, developed and applied hydrology become very important thing in the life due to the wide verity advantages for the applications of this field. Hydraulic Structures such as crump weir are placed in channels to estimate or measure flow rate and flow control devices. In this study there is a new performance for crump weir which appears by adding opening holes in the model  of crump weir. ...

We study the parsing complexity of Combinatory Categorial Grammar (CCG) in the formalism of Vijay-Shanker and Weir (1994). As our main result, we prove that any parsing algorithm for this formalism will necessarily take exponential time when the size of the grammar, and not only the length of the input sentence, is included in the analysis. This result sets the formalism of Vijay-Shanker and We...

With the exception of the undesirable characteristic of summer dormancy and the accompanying low aesthetic value, crested wheatgrass has many desirable characteristics in semiarid environments, making it a promising candidate for lower water use turf. Using a population of 27 half-sib families, this study characterized the underlying genetics of turf quality (based on a 1–9 rating scale) of cre...

In the present study, experimental investigations about the hydrodynamics of the conical cap tray (ConCap tray) have been carried out. The ConCap tray is an innovative and novel type of cap trays. The effect of the different weir height (2.5, 5 and 7 cm) on the weeping, entrainment and the total pressure drop for the ConCap tray was measured, compared and correlated. The hydraulic experiments w...

The effect of the outlet weir height on sieve tray performance is described in this paper. The studies were made to investigate the effect of the outlet weir height on sieve tray mass transfer efficiency and hydraulic performance. Tests were conducted in the 1.22 m diameter section of the Fractionation Research, Inc. (FRI) low-pressure column. Sieve trays with nominal hole areas of 14%, 13%, an...
