Other than this, Fig.1 also shows that the monomer concentration is the key factor to the molecular weight.

But excess liposome brings cytotoxicity, and inappropriate cell confluence, the ratio and quantity of vectors / liposome can affect transfection efficiency, while obtaining higher transfection efficiency and lower cytotoxicity were the key of a successful transfection.

So it is easily for the foreigner students to learn Mandarin by themselves through the computer-assisted language learning (CALL).The literature on CALL mentions a number of its potential advantages: elimination of time limitations and dependence on the teacher, possibility to work at the user’s own tempo and to store his/her profile in order to monitor the progress, constant access to a number of additional materials such as visualizations, recordings and animations as well as elimination of stress related to the fact that the learner is being listened to by his/her classmates, the last of which is particularly important while acquiring L2 (second language) pronunciation and prosody.[6] Summary The Mandarin speech teaching for foreign students has its own peculiarities, which is always a big problem for TCFL.

Analysis of the thermal behavior of a ball screw based on simulation and experimental investigation Zihan Li1, a, Kaiguo Fan1, b and Jianguo Yang1, c 1School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China alizihan123@sjtu.edu.cn, b fankg@sjtu.edu.cn, c jgyang@sjtu.edu.cn Keywords: Ball screw, Thermal behavior, Finite element analysis, Experimental investigation.
Fig.3 Schematic diagram of the finite element model The transient thermal characteristic of the ball screw during the warm-up phase is expressed as follows: (1) where A and V are the flank surface area and volume, respectively; hw is the forced convective heat transfer coefficient; ρ is the material density; specific heat is noted as c; and t denotes time.
According to Eqs. (3), and (4), the boundary conditions of the forced convective heat transfer coefficient hw and the total frictional heat qin can be calculated as: (8) where material density ρ is 7.85x103 kg/m3, specific heat c is 450.
