Predicting transpiration of shaded and non-shaded tomato fruits under greenhouse environments

Fruit water balance is determined by entry of sap through xylem and phloem, and losses due to back̄ow from fruits to other organs, and to transpiration. The latter, which may vary according to growing and climatic conditions, plays a signi®cant role in fruit water balance. To better understand and predict tomato fruit transpiration, measurements of the transpiration rate of shaded and nonshaded ...

Impossible Shaded Images

Abmact-In this correspondence, we show that images that could not have arisen from shading on a smooth surface with uniform reflecting properties and lighting exist. Much work has been done on recovering surface shape from images, and there has been some attention paid to the question of uniqueness. It has been shown, for example, that singular points curtail ambiguity. However, little has been...

Environmental factors influencing heat stress in feedlot cattle.

Data from 3 summer feedlot studies were utilized to determine the environmental factors that influence heat stress in cattle and also to determine wind speed (WSPD; m.s(-1)) and solar radiation (RAD; W.m(-2)) adjustments to the temperature-humidity index (THI). Visual assessments of heat stress, based on panting scores (0 = no panting to 4 = severe panting), were collected from 1400 to 1700. Me...
