We report the first extragalactic detection of the pure rotational H2 S(0) and S(1) lines at 28.2 and 17.0 m in the central 130 pc molecular complex of the nearby Scd galaxy NGC 6946. We deduce a temperature of this gas component of 170 K and a mass of 5 106 M for an ortho/para ratio of 3, corresponding to the ratio of statistical weights. The warm gas is confined to a 500 (135 pc) diameter reg...

From the point of view of a data warehouse system its part of collecting and receiving information from other systems is crucial for all subsequent business intelligence applications. The incoming information can be classified generally in two types, the state-snapshot data and the state-change or event data usually called transactional data, which contains information about the change processe...

We present 21-cm H i line and 408 MHz and 1.4 GHz continuum observations of the Magellanic dwarf galaxy UGCA 86, made with the DRAO synthesis telescope. UGCA 86 is detected in the continuum at both frequencies, with 408 MHz flux density S 408 = 120 ± 30 mJy and 1.4 GHz flux density S 1400 = 79 ± 3 mJy. The H i structure of UGCA 86 is complex, with two separate components: a rotating disk and a ...

The gender wage gap among adult full-time workers, after controlling for educational attainment and other observable characteristics, is about half the size it was in 1980. Using Census and Current Population Survey data from 1959 through 1999, we assess the relative contributions of two factors to the decline in the gender wage gap: changes across cohorts in the relative slopes of men’s and wo...

2. The percentage of children whose confirmatory testing results were communicated to their families by 4 months of age. In children with SCD, illness and death can be reduced through early diagnosis, treatment of complications, systematic follow-up, and patient/parent education. In particular, timely confirmatory testing and prompt communication with families are steps that pave the way for in...

Dispersing graphite into few-layers graphene sheets (GS) in water is very appealing as an environmental-friendly, low-cost, low-energy method of obtaining graphene. Very high GS concentrations in water (0.7 mg mL(-1)) were obtained by optimizing the nature of dispersant and the type of ultra-sonic generator. We find that a multi-step sonication procedure involving both tip and bath sources cons...
