Since interconnect is becoming a limiting constraint for microelectronics technology, VLSI design curricula and supporting CAD tools require significant change. We describe the introduction of Rensselaer’s Interconnect Performance Estimator (RIPE) into a VLSI design class.

Fruit ripeness identification is hard to measure especially when it involves color as main indicator. Suitable color model must be chosen to determine the right color for the ripeness identification. Hue, Saturation and Value (HSV) are proved to be a better choice because it can define the color intensity. Besides, it also helps to choose colors which are similar to the eyes. Manual grading pro...

Aqueous extracts of nine medicinal plants were bioassayed against larvae of Culex quinquefasciatus Say and Aedes aegypt (L.). Among these plants, the long pepper, Piper retrofractum Vahl (Piperaceae), showed the highest level of activity against mosquito larvae. To gain more information on larvicidal activity of P. retrofractum, fresh fruits of this plant were extracted in water and the extract...

SYNOPSIS. Ethanol is a naturally occurring substance resulting from the fermentation by yeast of fruit sugars. The association between yeasts and angiosperms dates to the Cretaceous, and dietary exposure of diverse frugivorous taxa to ethanol is similarly ancient. Ethanol plumes can potentially be used to localize ripe fruit, and consumption of low-concentration ethanol within fruit may act as ...

Strawberry (Fragaria x ananassa) fruit contains several anthocyanins that give the ripe fruits their attractive red color. The enzyme that catalyzes the formation of the first stable intermediate in the anthocyanin pathway is anthocyanidin-3-O-glucosyltransferase. A putative glycosyltransferase sequence (FaGT1) was cloned from a strawberry fruit cDNA library and the recombinant FaGT1 transferre...

Two cDNAs clones (Cel1 and Cel2) encoding divergent endo-beta-1, 4-glucanases (EGases) have been isolated from a cDNA library obtained from ripe strawberry (Fragaria x ananassa Duch) fruit. The analysis of the amino acid sequence suggests that Cel1 and Cel2 EGases have different secondary and tertiary structures and that they differ in the presence of potential N-glycosylation sites. By in vitr...

Coliform bacteria have long been associated with a "gassy" deterioration of olives. This deterioration may be characterized by the formation of blisters, resulting from accumulation of gases which separate the skin from the flesh of the olives or by the formation of fissures directly under the skin which may extend to the pit of the fruit as shown in Plate 1. The decomposition is not confined t...

The influence of maturing and ripening on phenylalanine ammonia-lyase (PAL) activity and anthocyanin accumulation was examined using bagged, non-bagged and shaded ‘Jonathan’ (Malus domestica) apples. Bagged fruit were covered with paper bags from mid-June at an early stage of fruit growth. Shaded apples were insulated from sunlight by newspaper at the beginning of colouring (middle September). ...

Ectopic expression of the strawberry (Fragaria×ananassa) gene FaPE1 encoding pectin methyl esterase produced in the wild species Fragaria vesca partially demethylated oligogalacturonides (OGAs), which conferred partial resistance of ripe fruits to the fungus Botrytis cinerea. Analyses of metabolic and transcriptional changes in the receptacle of the transgenic fruits revealed channelling of met...

Mango fruit (Mangifera indica L.), cv. ‘Cogshall’, ‘Kent’ and ‘Keitt’ were harvested at different maturities (61–115 d past flowering and 0–307 average g fresh weight for ‘Cogshall’) and at different sizes (364–1563 and 276–894 average g fresh weight for ‘Keitt’ and ‘Kent’, respecively). Immediately after harvest (green) or after 1 week of ripening at room temperature (ripe), fruit were homogen...
