Foliage and Fabrication
In my photographic work, I contrast natural and man-made objects abstracted by manipulation of scale. Details of the objects are blown up to proportions larger than life. By distorting the scale, I aim to allow the audience to view the image out of context, enabling the viewer to see it for its …

Foliage Echoes and Sensing in Natural Environments
Foliage is very common feature in the habitats of echolocation bats and thus its echoes constitute the major input of bats' sensory systems. Acquiring useful information from vegetation echoes facilitates the bats significantly in the navigation and foraging behaviors. To better understand the …

Biomimetic Detection of Dynamic Signatures in Foliage Echoes
… echoes from simple targets. However, complex foliage echoes, which comprise a large portion of the received echoes and contain useful information for these bats, have not been studied in prior research. We used a biomimetic sonarhead which replicated these dynamics, to collect a large dataset …

Solutions to Passageways Detection in Natural Foliage with Biomimetic Sonar Robot
… is capable of reliably finding narrow gaps in foliage to serve as a passageway to fly through. To investigate the sensory information under such capability, we have used a biomimetic sonar robot to collect the narrow gap echoes from an artificial hedge in a laboratory setup and from the natural …

The effects of adjuvents upon the pesticide uptake and penetration of foliage
The foliar uptake by wheat of the wild oat herbicide flampropmethyl has been studied following application of ul droplets of an aqueous solution. The results show that over the time required for the drop to dry the compound does not partition into the surface waxes and crystallises as an external …

Chemical interactions between rainfall and northern red oak (Quercus rubra l.) foliage
Nutrient ion exchange was examined between simulated acid rain solutions and northern red oak (Ouercus rubra L.) leaves of trees growing in fertile, limestone-derived soil and less fertile, sandstone/shale-derived soil. Leaves harvested from trees growing on the fertile site had greater …

Effects of Moisture on Combustion Characteristics of Live California Chaparral and Utah Foliage
Current fire-spread models are based largely on empirical correlations based on fires burning through dead pine needles. There is a need to increase the accuracy of modeling wildfires in live vegetation. This project investigates the quantitative and qualitative ignition characteristics of eight …

Terrestrial laser scanning to characterise three-dimensional foliage and woody material distributions in trees
Three-dimensional characterisation of foliage and wood distribution within forests is essential for understanding, managing and monitoring forest ecosystems. The recent advances in terrestrial laser scanning (TLS) technologies have provided new opportunities to measure the 3D structure of forest …

An HPLC method for simultaneous determination of residual benomyl and MBC on apple foliage without cleanup
… in apple leaves. The fate of benomyl on apple foliage after spray application of benomyl (Ben late 50 per cent wettable powder) was investigated by the method thus described. Benomyl quickly dissipated during the first 3-7 days, but the dissipatio'n sltowed down thereafter. In contrast, the …

Physiological responses of sun and shade foliage in thinned and unthinned ten-year-old loblolly pine stands
… for upper (sun) and lower (shade) crown foliage were examined. Xylem water potential, litterfall dynamics and tree growth were monitored. Nutrient availability, chlorophyll content and chlorophyll a/b ratio were assessed. At the end of the third post-thinning growing season (eleventh …

Stress detection in loblolly pine using relative apparent temperatures
… from non-stressed loblolly pine by increased foliage temperatures was tested. The foliage temperatures of seedlings and trees were measured with an AGA Thermovision 680 system, imported by the AGA Corporation, Secaucus, New Jersey. The AGA Thermovision 680 system is a simple, easily …

Variations in needle morphology and anatomy as related to variations in photosynthetic potential within loblolly pine (Pinus taeda L.) canopies
… in relation to photosynthetic potential for foliage from six positions within the canopies of three Loblolly Pine trees. The six positions represented two distinct lightning conditions, open and closed grown, and three vertical positions, top, middle and bottom on the canopies of the three …

SIMULATED MINE LAND RECLAMATION IMPACT ON BIOMASS PARTITIONING AND NUTRIENT CONTENTS IN LOBLOLLY PINE
… Allometric equations relating dry weights of foliage, stem, branches and roots to diameter at groundline and height were developed to estimate tree biomass. Estimated biomass accumulation improved with FRA treatment which produced a mean of 759 g foliage, 344 g branch, 440 g stem, 273 g root, …
