    Abstract: Collapsible behaviour of soil is considered as one of the major problems in the stability of roadway embankment, the lack of cohesion between soil particles and its sensitivity to the change of moisture content are reasons for such problem. Creation of such cohesion may be achieved by implementation of liquid asphalt and introduction of Nano additi... Show More

    Abstract: The sweetening process is investigated in this paper. The superficial velocity and the characteristic length is evaluated in this research. The results dhow the X factor as sweetening index is improved with the increasing the characteristic length and the decreasing the superficial velocity. In addition, the increase in the amount of charachtristic... Show More

    Abstract: To study on mixed fermentation of probiotics, bacterial cultivation was carried out firstly. It was showed that the optimal pH values for growth of Lactobacillus, Yeast and Bacillus subtilis were 6.5, 6.0 and 7.0, respectively. And the suitable temperature for all of them was about 31°C. Then under selective conditions pH 6.0, 31°C and 160 r/min, t... Show More

    Abstract: Lactic acid bacteria (LAB) play an important role in fermented food preservation thank to their antifungal ability as well as bacteriocin activity. Fermented meat products including Nem chua are usually placed under negative effects due to typical manual production process, uncontrolled ambient preservation condition, and consuming without cooking....
