In order to aging study of the compsite solid propellants, usually the changes in propellant properties during warehousing and storage are measured, and then the shelf life of them estimated. In this regard, by applying the common methods based on mechanical tests, chemical and thermal analysis, the propellant properties due to aging and time lapse are measured. In this paper, first we remark t...
This study examined English pronunciation by Cantonese speakers in Hong Kong with the International Phonetic Alphabet (IPA) to see how the application of IPA can be used in language education. Twenty university students, divided into two groups, one with the IPA training and the other without the training, were asked to read 30 English words (5 controls) that contain challenging sounds (e.g., l...
to provide an objective phonetic description of vowels and diphthongs of Indian English in acoustic terms and to provide acoustic evidence of sound change in English in language contact situation. This of course would have implications in ESL in India, as knowledge about the vowel space and vowel qualities produced by speakers in India can help us in teaching spoken English to the student...
the effect of sonication time (in three levels 0,2,4 min ) and mono- di glyceride (in three levels 0,0.3,0.6 %) on improving the quality of cupcake were studied. color analyze (l*, a*,b*) for dough samples and specific volume, porosity shelf life, color analyze and texture of cake were done. results showed that increasing the levels of each factors (sonication and emulsifier) made a decrease in...
— For predicting the shelf life of processed cheese stored at 7-8º C, Elman single and multilayer models were developed and compared. The input variables used for developing were applied in order to compare the prediction ability of the developed models. The Elman models got simulated very well and showed excellent agreement between the experimental data and the predicted values, suggesting tha...
the effects of grape pomace extract (0, 2 and 4%) on quality and shelf life of silver carp ( hypophthalmicthys molitrix ) fillets during chill storage (4°c) were investigated. the control and the treated fillets were analyzed periodically for microbiological (tvc and ptc), chemical (tvb-n), and sensory characteristics. the results showed that grape pomace-treated samples have lower tvb-n (24.2 ...
in this research, different concentrations of xanthan and lepidium perfoliatum seed gums (0.1, 0.2 and 0.3%) were used to improve the quality and shelf-life of chiffon cake. for this purpose, specific gravity and apparent viscosity of batter, and the volume, specific volume, moisture, sensory and texture properties, crumb and crust color were examined. to investigate the effect of gums on the s...
