This is a new way for China＇ s new personnel training, and also proposes higher requirements on this type of personnel training institutions. In view of the demands of society and different majors on personnel, an enhancement to the standardized management of electronic laboratory operations becomes one of the important tasks for personnel training institutions. In this paper, how to practice the standardization management in an all-round way is discussed centered at college and university students＇ electronic laboratory.展开更多

The training of digital media professionals has developed into one of important ways and methods for conforming to the trend of economic development and improving the national economic power. In this paper, the current situations of China＇ s current digital media professional personnel training model and other cotmtries＇ digital media professional personnel training model are comparatively analyzed for studying the characteristics of Chinese and foreign digital media professional personnel training models, absorbing the advanced, excellent digital media professional experience in personnel training model, and providing a reference for the training of the digital media professional personnel in China.展开更多

To estimate the re- productive success of breeders, three independent full-factorial crosses were created and the fins of breeders and progenies were sampled for microsatellite analysis. Out of 959 offspring from three sets, 99.6% were assigned to their parents using 6-7 mi- crosatellite markers. In all crosses, some parent pairs produced a large number of offspring and some parent pairs did not produce any offspring. The contributions of male or female parents were unequal, ranging from 1.0-89.3% across the three sets. The loss of putative Ne was 69.6% in set 1, 31.2% in set 2 and 57.6% in set 3. These results suggest that the unequal contribution of parents is universal in artificial breeding ofL. crocea, especially in a small population, and this should be taken into account in hatcheries or when releasing animals for resource enhancement展开更多

The aim of the current work is to numerically model the air speed and temperature in a forced ventilation piggery to achieve optimum environmental control. This work can also help to identify problems in the design of piggeries and offer suggestions for improvements. A steady two-dimensional numerical model including the effect of buoyancy, turbulence and heat generated by the pigs was solved using the computational fluid dynamics software Fluent, using the integral volume method. Air speed and temperature inside the piggery and at the pigs level were predicted for three different locations of ventilation opening, inlet velocities in the range (0.3 - 7 m/s), insulation or no insulation in the external walls, and for 5 ℃ and 32℃ ambient temperatures.展开更多
