متن کاملCorneal topographic astigmatism (CorT) to quantify total corneal astigmatism.
PURPOSE To evaluate the performance of corneal topographic astigmatism (CorT) based on total corneal power measurements. METHODS Anterior, posterior, and total corneal power measurements of 526 virgin eyes obtained using the CSO Sirius tomographer (Costuzione Strumenti Oftalmici, Scandicci, Florence, Italy) were analyzed. Individual CorTs were created from each set of data. These CorTs were a...

متن کاملAdapting to Change
Biologists typically use the climatic conditions in which species currently live to project the likelihood that those climates will be available following a period of climate change, and these almost always predict dramatically high rates of species extinctions and biodiversity loss in future climates. In many instances, such predictions are warranted. Polar bears (Ursus maritimus), for example...
متن کاملAdapting SimpleNLG to Spanish
We describe SimpleNLG-ES, an adaptation of the SimpleNLG realization library for the Spanish language. Our implementation is based on the bilingual English-French SimpleNLG-EnFr adaptation. The library has been tested using a battery of examples that ensure that the most common syntax, morphology and orthography rules for Spanish are met. The library is currently being used in three different p...
