A nidovirus was isolated from crucian carp (Carassius auratus). The complete genome of the crucian carp nidovirus (CCNV) is 25,971 nt long and has five open reading frames, encoding the polyprotein 1ab (pp1ab), spike glycoprotein (S), membrane protein (M), and nucleocapsid protein (N). CCNV has the highest similarity to Chinook salmon nidovirus (CSNV). However, the CCNV HB93 pp1ab protein sequence...
The technology of leak protection and leak control while drilling through physical methods can be successfully applied based on studying the annulus' behaviour of the whole down hole flow field. In this paper, the model of sealing down hole while drilling through physical methods which will be used for CFD simulation is eatablished through reasonable simplification. Then running numerical simulation...
Air drilling is a drilling technology which uses air as the recirculated medium. There are many differences in the pressure distribution of circulatory system, the choice of drilling machinery and the configuration of drilling parameters between air drilling and other conventional drilling technologies. In this paper, we mainly focused on the force analysis and mechanism of rock chip in air drilling,...
On the stochastic models of economic optimization of Prof. Chen M F, this paper chooses Prescott's paradigm to analyze how optimally to allocate the investment of Jiangsu Province to coordinate the comovements of Jiangsu's transportation and non-transportation, acquires a optimal stochastic controllable model for the coordinated developing, finds a worthy Euler equation of this model, does a numerical...
On the stochastic models of economic optimization of Prof. Chen M F, this paper chooses Prescott's paradigm to analyze China's optimum economic growth, finds a stochastic optimal control model for China's economic growth, acquires a worthy Euler equation of this model, and gives the optimal numerical solution of this model, which would help planners could easily allocate investment of capital and...
