Thirteen polyphenolics were isolated from fresh pods of Caesalpinia pulcherrima using various methods of column chromatography. The structures of these polyphenolics were elucidated as gallic acid (1), methyl gallate (2), 6-O-galloyl-d-glucoside (3), methyl 6-O-galloyl-β-d-glucoside (4), methyl 3,6-di-O-galloyl-α-d-glucopyranoside (5), gentisic acid 5-O-α-d-(6'-O-galloyl)glucopyranoside (6), gu...

The effects of increased sink-source ratios, induced by elevating night temperatures, on remobilization of (14)C-assimilates and N within field-grown soybeans (Glycine max [L.] Merr.) was investigated from preflowering to maturity. Raising the mean minimum night temperature for the entire growing season from 10 (check, uncontrolled) to 16 degrees C increased seed growth without appreciable effe...

The present study investigated the use of fermented Prosopis juliflora pods (PJP) as a carbohydrate source, alternative to rice bran (RB), and a PJP based diet formulation supplemented with probiotics Lactobacillus acidophilus (LA), Lactobacillus bulgaricus 009 (LB) and Streptococcus thermophilus (ST) on the growth of Labeo rohita (rohu) fingerlings. The diets were isonitrogenous (39%) and isoe...

Snap bean (Phaseolus vulgaris L.) cultivars with pods representing a range of greenness were grown in Oklahoma field trials in 2001 and 2004. Objective color evaluations (L* value and hue angle) performed on raw and cooked pod samples from 10 (2001) or 12 (2004) of these cultivars indicated that color testing of raw snap bean pods may not be sufficient to determine the color after cooking. Alth...

To assist nature observation, we take on the challenge of detecting the species of a flying bird using a single camera. We study the bird flying data and find that a bird body axis is an invariant dimension during flight. We then develop a model-based detection approach that verifies the body axis information with the known bird flying dynamics. As a commonly used method, an extended Kalman fil...

Dry bean (Phaseolus vulgaris L.) seeds are a rich source of dietary zinc, especially for people consuming plant-based diets. Within P. vulgaris there is at least two-fold variation in seed Zn concentration. Genetic studies have revealed seed Zn differences to be controlled by a single gene in two closely related navy bean genotypes, Albion and Voyager. In this study, these two genotypes were gr...

The Sensor Web is a macro-instrument concept that allows for the spatiotemporal understanding of an environment through coordinated efforts between multiple numbers and types of sensing platforms, including both orbital and terrestrial and both fixed and mobile. Each of these platforms, or pods, communicates within their local neighborhood and thus distributes information to the instrument as a...

Plants are rich in a variety of chemical compounds. Many are secondary metabolites including aromatic substances most of them are phenols or their oxygen substituted derivatives. Medicinal plants are rich in antioxidant constituents such as phenols, tocopherols, ascorbic acid, carotenoids, and flavonoids etc. They are found to acquire free radical scavenging activity and used worldwide for the ...

Many people die owing to the shortage of donor organs. Medical examiners and coroners (MEs/Cs) play a vital role in making organs available for potential recipients. Medical examiners'/coroners' case data were collected using a structured confirmatory-recorded methodology for calendar years 2000-01 and were linked and analyzed with donor and transplant data from the United Network for Organ Sha...
