  • Improving students' listening comprehension through focused listening tasks

    • Authors: Hoang, Phuong Thao;  Advisor: Tran, Hien Lan (2010)

  • In recent years, English has become a compulsory subject in high schools in Vietnam, the need, therefore, to learn English is greater than ever before. However, almost all students do not have chances to develop listening skill at high school and listening is regarded as one of the hardest skills for the students. There are various reasons for this: the students’ motivation, linguistic knowledge,background and experience are poor, the listening situation is unfamiliar to the students, and the teaching methods of some teachers are not really effective

  • Screening Streptomycin Resistant Mutations from Gamma Ray Irradiated Bacillus subtilis B5 for Selection of Potential Mutants with high Production of Protease

    • Authors: Tran, Bang Diep; Nguyen, Thi Thom; Hoang, Dang Sang; Hoang, Phuong Thao; Nguyen, Van Binh; Ta, Bich Thuan; Vo, Thi Thuong Lan; Tran, Minh Quynh (2016)

  • The suspensions of Bacillus subtilis B5, a rather high protease production strain, in logarithmic growth phase were irradiated under gamma Cobalt-60 source at Hanoi Irradiation Center. After treatment, the irradiated cells were intermediately cultured in the nutrient agar plates supplemented without and with 20µg/ml streptomycin for screening. The radiation effects on their viability and mutant frequency were studied with radiation dose. The results showed that its survival rate was reduced with the dose as biphasic function. The cells irradiated at dose higher than 1200 Gy do not form colony in the medium containing streptomycin though they could survive in nutrient agar. Therefore...
