study of freezing and thawing cycles influence on durability of stablized eolian sand sediment
with considerable dispersion in many areas of the world sediments are among the most important sediments in deserted environments. a stabilization method for this type of beds is making use of the setting property of natural pozzolana in the vicinity of lime. these soils have little strength, both in natural humidity as well as in full saturation conditions. their dispersion in many areas of th...
متن کاملUltrasonic monitoring of fish thawing process optimal time of thawing and effect of freezing/thawing.
INTRODUCTION Fish quality is traditionally controlled by chemical and microbiological analysis. The non-destructive control presents an enormous professional interest thanks to the technical contribution and precision of the analysis to which it leads. This paper presents the results obtained from a characterisation of fish thaw-ing process by the ultrasonic technique, with monitoring thermal p...
متن کاملGenetic basis of evolutionary adaptation by Escherichia coli to stressful cycles of freezing, thawing and growth.
Microbial evolution experiments offer a powerful approach for coupling changes in complex phenotypes, including fitness and its components, with specific mutations. Here we investigate mutations substituted in 15 lines of Escherichia coli that evolved for 1000 generations under freeze-thaw-growth (FTG) conditions. To investigate the genetic basis of their improvements, we screened many of the l...
متن کاملEffects of multiple freezing and refrigerator thawing cycles on the quality changes of sea bass (Dicentrarchus labrax)
The freezing-thawing effect on the meat quality of whole, gutted and fillets of sea bass (Dicentrarchus labrax) were investigated. It was aimed to investigate the changes in the meat quality of whole, gutted and fillets of sea bass in multiple frozen (-18±2ºC) and thawed cycles in refrigerated conditions (4±2°C). The meat quality assessment of the sea bass groups (whole, gutted and fillets) sub...
متن کاملQuality Evaluation of Pork with Various Freezing and Thawing Methods.
In this study, the physicochemical and sensory quality characteristics due to the influence of various thawing methods on electro-magnetic and air blast frozen pork were examined. The packaged pork samples, which were frozen by air blast freezing at -45℃ or electro-magnetic freezing at -55℃, were thawed using 4 different methods: refrigeration (4±1℃), room temperature (RT, 25℃), cold water (15℃...
