The lobes of the NASA ULDB pumpkin-shaped super-pressure balloons are made of a thin polymeric film that shows considerable time-dependent behaviour. A nonlinear viscoelastic model based on experimental measurements has been recently established for this film. This paper presents a simulation of the viscoelastic behaviour of ULDB balloons with the finite element software ABAQUS. First, the stan...

The ribosomal DNA (rDNA) of Cucurbita pepo L. has been found to consist of tandemly arrayed repeat units, most of which are 10 kilobases in length. Thirty-six repeat units, cloned into the HindIII site of pACYC 177, fall into seven classes which differ from each other in length and/or nucleotide sequence. Most of the heterogeneity occurs in noncoding portions of the repeat unit although there i...

Rapid color degradation during processing and storage is a limitation when using strawberry puree (SP). This work aimed to use image analysis coupled with two machine learning algorithms: ordinary least squares (OLS) artificial neural networks (ANNs), predict anthocyanin content (AC) in frozen SP its at –18°C for 120 days. When applying the OLS regression model, unsatisfactory AC prediction val...

Oxidation processes in milk and yogurt during the shelf life can result in an alteration of protein and lipid constituents. Therefore, the antioxidant properties of yogurt in standard conditions of preservation were evaluated. Total phenols, free radical scavenger activity, degree of lipid peroxidation, and protein oxidation were determined in plain and skim yogurts with or without fruit puree....

Spray-drying, which has been used for commercial production of functional ingredients from several fruits and vegetables, has not yet been studied for sweetpotato processing. Thus, the objective was to determine the effects of viscosity reduction of sweetpotato puree with alpha-amylase, maltodextrin (MD) addition, and inlet air temperature on the physicochemical characteristics of spray-dried s...

We present here the first complete Squash leaf curl China virus (SLCCV) genomic segment DNA-A sequence from East Timor. It was isolated from a pumpkin plant. When compared with 15 complete SLCCV DNA-A genome sequences from other world regions, it most resembled the Malaysian isolate MC1 sequence.
