Yield gap analysis provides an essential framework to prioritize research and policy efforts to reduce yield constraints. To identify options for increasing chickpea yield, the SSM-chickpea model was parameterized and evaluated. The model was applied to analyze seed yield at both potential and water limited production levels and subsequently to find the yield gap for nine different locatio...

In the paper a model to predict the concentrations of particulate matter PM10, PM2.5, SO2, NO, CO and O3 for a chosen number of hours forward is proposed. The method requires historical data for a large number of points in time, particularly weather forecast data, actual weather data and pollution data. The idea is that by matching forecast data with similar forecast data in the historical data...

typed double-spaced (including references) with conventional margins. The overall length is limited to five manuscript pages, including not more than one figure or one table. To the Editor: Ionized calcium is now the measurement of choice for evaluating calcium metabolic diseases (1, 2). Ionized calcium may be reported either as the actual ionized calcium, referred to the actual pH of the patie...

Explosion in the number of ‘relevant’ sites (on any topic) on the Web creates a need to identify additional measures, such as quality or reliability, to rank content on the Web. Recent research has used the term authoritative to represent a broader notion of the goodness of a web page. An authoritative page is one that is both relevant and reliable, in the spirit of an “authority” on a subject....
