A new method of quantifying dermal perfusion on a regional basis using a dynamic thermographic technique is investigated. The technique is based on the relationship between dermal perfusion and the rate of skin surface reheating following the application of a transient cold challenge predicted by a theoretical model. Measurements were made using images from(More)
Benzyladenine (BA) is the only cytokinin to effectively induce shoot multiplication in vitro between genotypes of the important dune grass species Uniola paniculata (sea oats). However, a significant genotype-specific negative carryover effect of BA on ex vitro acclimatization has been observed. In the present study, the effects of multiplication media(More)
Net photosynthetic rates (P n) of easy (EK 16-3) and difficult-to-acclimatize (EK 11-1) sea oats genotypes were examined under the following culture conditions: (1) photoautotrophic [sugar-free medium, high photosynthetic photon flux (PPF), high vessel ventilation rates and CO2 enrichment, (PA)]; (2) modified photomixotrophic [sugar-containing medium(More)
The photosynthetic and carbohydrate status of an easy-to-acclimatize (EK 16-3) and a difficult-to-acclimatize (EK 11-1) genotype of Uniola paniculata L. (sea oats), a native dune species of the southeastern US, were evaluated during in vitro culture and ex vitro acclimatization. Net photosynthetic rate was eight times greater for EK 16-3 than EK 11-1(More)
R ussell (1999) compiled a large bibliography of research demonstrating that there is not a significant difference between standard and distance education learning. Yet rapid advances in the use of technology for the discipline of horticulture have been shown to improve student learning outcomes, increase student enrollment, and foster better teachers(More)
A wild-type selection of heavenly bamboo (Nandina domestica) and ten cultivars were evaluated for plant performance, growth, flowering, and fruiting in north and south Florida. Onset of flowering generally began by March and April in south Florida and 4 to 8 weeks later in north Florida. Fruit was first noted 8 to 16 weeks after most selections began(More)
Japanese silver grass (Miscanthus sinensis) and 14 cultivars were transplanted in northern and southern Florida and evaluated for landscape performance, fl owering, growth, and seed viability. All plants survived the 84-week study at both locations with the exception of ‘Morning Light’, where 22% to 33% of the plants died. In northern and southern Florida,(More)
Seed propagated blanket flower (Gaillardia pulchella Foug.) were container grown in a peator compost-based medium under greenhouse conditions for 10 weeks. The formulated compost-based medium had lower initial moisture, pH, total porosity, and container capacity; and higher bulk and particle density than the other media. The compost-based medium and(More)
A panel of 5 experienced electroencephalographers detected spikes in EEG trials from 40 epilepsy patients and 10 control subjects. 1952 spikes were detected, and detailed attribute scores were recorded. Statistics from the theory of measurement error are utilized to quantify the reliability and difficulty of the study. An extension of the Pearson(More)
