A model stomach system was used to investigate disintegration of various foods in simulated gastric environment. Food disintegration modes and typical disintegration profiles are summarized in this paper. Mechanisms contributing to the disintegration kinetics of different foods were investigated as related to acidity, temperature, and enzymatic effect on the texture and changes in microstructur...

in the present study, the mechanical behavior of aa5052 aluminum alloy during cold deformation and subsequent isothermal annealing in a temperature range of 225-300oc was investigated using the uniaxial tensile test data. it is found that by increasing the annealing time and temperature the material yield strength is decreased. the microstructural investigations of the annealed samples show tha...

Decarburization is generally avoided as it reckoned to be a process detrimental material surface properties. Based on the idea of duplex engineering, i.e., nitriding case-hardened or through-hardened bearing steels for enhanced performance, this work deliberately applied decarburization prior plasma cancel softening effect decarburizing with and at same time significantly promote kinetics. To m...

The development of Wyoming’s energy resources (coal bed methane extraction [CBM], hydraulic fracturing) and carbon dioxide (CO2) sequestration sites all invariably result in the production of brackish wastewaters. The treatability of these waters varies from relatively simple for CBM water (dissolved solids < 2,000 mg/L) to complex for the water that is displaced during geologic sequestration o...

In (Modern) Greek, velar consonants become palatalized before front vowels following an allophonic rule. In many southern dialects, the variants that result from palatalization further undergo softening in this same position. While velar softening is well-documented in Greek dialectology studies, most previous work is based on impressionistic data. In the present study, several acoustic and psy...

Constitutive equations of cyclic strain and stress softening for materials with low internal stress levels are derived from the rate theory. The study shows that over the high stress and low temperature range where the description of plastic flow in cyclic softening can be approximated with activation over a single energy barrier, cyclic strain softening is well related to stress relaxation pro...

Polygalacturonase (PG) is an important hydrolytic enzyme involved in pectin degradation during fruit softening. However, the roles of PG family members in fruit softening remain unclear. We identified 45 PpPG genes in the peach genome which are clustered into six subclasses. PpPGs consist of four to nine exons and three to eight introns, and the exon/intron structure is basically conserved in a...
