Chloroplast suspensions from spinach (Spinacia oleracea L.) were clearly resolved into intact and stripped chloroplasts by isopycnic centrifugation in density gradients of silica sol ("Ludox") and polyethlene glycol. The intact chloroplasts fixed CO(2) and evolved O(2) more rapidly than the crude suspensions; the stripped chloroplasts were inactive. During the photosynthetic fixation of (14)CO(...

The present study was conducted in Brgy. Dangcol, Balanga City, Bataan to evaluate the effect of bagging whole panicle (cluster) carabao mango fruit with waxed paper bag as compared traditional method and without terms yield quality well cost-benefit analysis. Results revealed that fruits bagged per cluster using (T3) obtained highest number marketable (130.60) total weight 34.21 kg while XL no...

This study explored the extent to which schoolchildren purchased precut and bagged fruits and vegetables from a mobile fruit vendor (frutero). During 14 days in fall 2008, a frutero sold fruits and vegetables at the entrance of an elementary school; 59% of the frutero's 233 consumers of 248 items were elementary-school students. With each successive day, an average of 1 additional bag of fruits...

Discourse is coming in from the cold. After years of being ignored by researchers in other areas of computational linguistics and language technology, many of these same researchers are beginning to think that their own work could benefit from treating text as more than just a bag of sentences. That is, they are beginning to think that discourse offers some low-hanging fruit—achievable improvem...

Ecological complexity has been proposed to play a crucial role in primate brain-size evolution. However, detailed quantification of ecological complexity is still limited. Here we assess the spatio-temporal distribution of tropical fruits and young leaves, two primary chimpanzee (Pan troglodytes) foods, focusing on the predictability of their availability in individual trees. Using up to 20 yea...

1. Current studies indicate that estimates of thermal tolerance limits in ectotherms depend on the experimental protocol used, with slower and presumably more ecologically relevant rates of warming negatively affecting the upper thermal limits (CTmax). Recent empirical evidence also gives credence to earlier speculations suggesting that estimates of heritability could drop with slower heating r...

OBJECTIVE To investigate eye injuries resulting from frontal automobile crashes and to determine the effects of frontal air bags. METHODS The National Automotive Sampling System database files from January 1, 1993, through December 31, 1999, were examined in a 3-part study that included an investigation of 22 236 individual crashes that occurred in the United States. A new 4-level eye injury ...
