OBJECTIVE Estimate cataract surgical rates (CSR) for Brazil and each federal unit in 2006 and 2007 based on the number of surgeries performed by the Unified Health System to help plan a comprehensive ophthalmology network in order to eliminate cataract blindness in compliance with the target set by the World Health Organization (WHO) of 3,000 cataract surgeries per million inhabitants per year....

The current study replicates and extends the finding (Hamlin, Wynn & Bloom, 2007) that infants prefer individuals who act prosocially toward unrelated third parties over those who act antisocially. Using different stimuli from those used by Hamlin, Wynn & Bloom (2007), somewhat younger subjects, and 2 additional social scenarios, we replicated the findings that (a) infants prefer those who beha...

OBJECTIVE Trinidad and Tobago has experienced an epidemiological transition over recent decades characterised by reduced rates of communicable diseases but rapidly increasing rates of obesity and non-communicable chronic diseases. The objective of the present study was to investigate the changes in energy and nutrient supply that have taken place in Trinidad and Tobago between 1961 and 2007. ...

Scirtothrips perseae Nakahara was discovered attacking avocados in California, USA, in 1996. Host plant surveys in California indicated that S. perseae has a highly restricted host range with larvae being found only on avocados, while adults were collected from 11 different plant species. As part of a management program for this pest, a ‘‘classical’’ biological control program was initiated and...

Reconstructing a 3Dmodel of a human face fromamonocular video sequence is an important problem in computer vision, with applications to recognition, surveillance, multimedia, etc. However, the quality of 3D reconstructions using structure frommotion (SfM) algorithms is often not satisfactory. One of the reasons is the poor quality of the input video data. Hence, it is important that 3D face rec...

We present the results of an analysis of ultraviolet observations of T Tauri Stars (TTS). By analysing emission measures taken from the literature we derive rates of ionizing photons from the chromospheres of 5 classical TTS in the range ∼ 10 41 –10 44 photons s −1 , although these values are subject to large uncertainties. We propose that the He II/C IV line ratio can be used as a reddening-in...
