Objective:To construct three recombinant shuttle plasmids of adenovirus expression vector which can express hepatitis C virus(HCV) different structure genes(C,C+E1,C+E1+E2) in order to pack adenovirus expression vectors which can express HCV different structure gene effectively.
Allinm Ovalifolium was soaked for 90s with 0.25% NaHSO4 hot solution, then it was throwed off the surface water and cooled, and it was put into drying room with 90℃ for 15min, then adjusted the drying room's temperature to 60℃, and it was continued to dry 10~12h, at last it was vacuumized to pack, green qualified product was acquired.
The antibacterial ability of copper has a potential application in the field of disinfection, food packaging and piping of drinking water.
The results indicate that the sensor presented better performances and that the bonding techniques can be used in MEMS packaging.
Light-weight high-silicon aluminum alloys are used for electronic packaging in the aviation and spaceflight industry.
The present paper summarizes the recent technical progresses in large process plants and the aviation industry, micro chemo-mechanical systems, fuel cells, high-temperature electronics, and packaging and coating technologies.
Chromatin is designed to allow both tight DNA packaging and proper functioning and regulation of enzymes such as DNA and RNA polymerases.
First, a detailed multi-body dynamic model of the vehicle is established by using the ADAMS/View software package, which is followed by validation using a vehicle field test.
The data collected by image analysis were analyzed statistically with Statistical Package for the Social Science.
In the end, the performance of the scheduling strategy based on the fault-tolerant grid-scheduling model is analyzed by an software package, named SPNP.
Fabrication of an electronic package box of SiCP/Al composites with high volume SiCP
In this paper, a SiCP preform was prepared by Powder Injection Molding (PIM), and the melting aluminum was injected into the SiCP preform by the pressure infiltration method to manufacture an electronic package box of SiCP (65%)/Al composites.
How Proteins Pack into Crystals: Nuclei Achieve Translation Symmetries by Growing
How protein molecules pack into a crystal remains problematic.
At the time of study, the ice cover was represented by thick one-year old ice (up to 1.2 m), perennial ice (up to 1.85 m), and pack ice.
It is shown that the low pitting resistance of the cladding layers of bimetals, which are currently produced by the pack rolling method, is the central problem.
Regarding different habitats, the relative occurrences of white whales in open water, in water openings in the ice, near the edge of pack ice, and in ice packs with different degrees of closeness are 21.5, 11.4, 45.7, and 21.4%, respectively.
