Secretory expression of the recombinant FGF-2 protein in Pichia pastoris carrying multiple copies of target geneAs a result, the yield of FGF-2 protein in this study was lower than other expression systems in previous studies of P. pastoris9,21, where the culture condition was optimized for methanol concentration, pH, and induction time. Therefore, the efficiency of the P. pastoris strain in this study could be improved by optimized shake-flask condition...

Evaluation of low energy X-Ray depth dose distribution by gafchromic film for dosimetry in food irradiationThe depth dose profile in the PMMA phantom is shown in Figure 5, and expressed in logarithm scale. As seen in the figure, the absorbed dose was almost attenuated within 30 mm thickness of the phantom. At 1.58 mm depth near the surface, the highest attenuation is observed; here, approximately 50% of the total attenuation was generated. After tha...

Bio-Electro-Fenton: A novel method for treating leachate in Da Phuoc Landfill, Viet NamEffect of airflow on the Bio-Electro-Fenton process Oxy is one of the key parameters in the BEF system, which is the electron acceptor in the cathode chamber to produce H2O2. High airflow rate could enhance the dissolved oxygen in solution and promote the oxygen mass transfer rate, and thus, is beneficial for H2O2 production and accumulation i...

Design of magnetron co-Sputtering configuration for preparing magnesium tin silicide-based thermoelectric alloy thin filmsInitial results of the MgSiSn thin films Figure 2 shows the crystalline structure of the MgSiSn thin films. There are two peaks at 33.18o and 47.92o which belong to the (200) and (220) plane of the Si substrate, respectively. A clear peak located at ~34.50o is found to be the (002) plane of metal Mg phase (JCPDS 35-0821). The existence of a se...

Using edge elements for modeling of 3-D magnetodynamic problem via a subproblem methodThe 3-D dimensional mesh with edge elements is depicted in Figure 4. The problem with the coil alone is first considered. The distribution of magnetic flux density generated by the excited electric current in the coil is pointed out in Figure 5. The computed results on the of the z-component of the magnetic flux density along the lines A1-B1 and...
