Interception of photosynthetically active radiation (PAR) was evaluated relative to greenness and normalized difference [MSS (7 5)/(7 + 5)] for five planting dates of wheat for 1978-79 and 1979-80 at Phoenix, Arizona. Intercepted PAR was calculated from leaf area index and stage of growth. Linear relationships were found with greenness and normalized difference with separate relationships descr...

Previous studies document Nukuleka in the Kingdom of Tonga as a founder colony for first settlement of Polynesia by Lapita peoples. A limited number of radiocarbon dates are one line of evidence supporting this claim, but they cannot precisely establish when this event occurred, nor can they afford a detailed chronology for sequent occupation. High precision U/Th dates of Acropora coral files (...

When the exchange rate is either fixed or floating, the currency trading of the central bank is relatively well understood. In intermediate regimes, or ‘dirty floats’, three different alternative behaviours of the central bank can be conjectured: symmetrically preventing changes of the exchange rate vs. preventing appreciation vs. preventing depreciation. In this paper, we describe a testing st...

John Rita, the Notre D am e Law g r a d u a te ac c u s e d of k ill ing th e n Notre D am e f r e s h m a n M a ra Fox with his ca r in the ear ly m orn ing hours of Nov. 13, 1993, will plead guilty on Feb. 6 to a m isdem eanor charge similar to his original felony charge of leaving the scene of a fatal accident. After deliberating for nine hours, a jury acquitted Rita in 1994 of caus­ ing F o...

Visual and near-infrared colours are used to identify intermediate-age globular cluster in early-type galaxies. In NGC 5846 and NGC 4365 colour-colour diagrams (V-I vs. V-K) reveal a sub-population in the globular cluster systems with an age much younger than the expected old populations (13-15 Gyr). A comparison with SSP models dates the formation of this younger population 2-7 Gyr back. Furth...

Throughout the Southern Great Plains, wheat is managed frequently as a dual-purpose crop, but this production paradigm is not necessarily applicable throughout other regions of the United States, and a wider array of management options can be considered for forage-only uses of cereal grains. Our objectives were to assess the fall-growth potential of wheat (Triticum aestivum L.), triticale (X Tr...

With genomic data, alignments can be assembled that greatly increase the number of informative sites for analysis of molecular divergence dates. Here, we present an estimate of the molecular divergence dates for all of the major primate groups. These date estimates are based on a Bayesian analysis of approximately 59.8 kbp of genomic data from 13 primates and 6 mammalian outgroups, using a rang...

We study the scheduling situation where n tasks, subjected to release dates and due dates, have to be scheduled on m parallel processors. We show that, when tasks have unit processing times and either require 1 or m processors simultaneously, the minimum maximal tardiness can be computed in polynomial time. Two algorithms are described. The first one is based on a linear programming formulation...

The correction of handwritten word skew is an arduous task that must be independent of due to style and writing conditions variations. We propose here a morphology-based method to detect and correct handwritten word skew in the treatment of dates written on bank checks. Our aim is to limit the number of parameters and heuristic features necessary for a good skew correction. Our approach is base...
