Arabidopsis E3 ligase salt- and drought-induced RING-finger 1 (SDIR1) has been found to be involved in abscisic acid (ABA)-related stress signaling. SDIR1-overexpressing Arabidopsis plants exhibit improved tolerance to drought. Tobacco (Nicotiana tabacum) and rice (Oryza sativa) are two important agronomic crop plants. To determine whether SDIR1 enhances(More)
Chinese text automatic proofreading opens up broad possibilities for the application of natural language processing. According to the distribution of Chinese single-character after word segmentation in Chinese text with the characteristic of errors and character trigram model, presents an effective text automatic proofreading algorithm. Experiments show(More)
To reduce the need for antibiotics in animal production, alternative approaches are needed to control infection. We hypothesized that overexpression of native defensin genes will provide food animals with enhanced resistance to bacterial infections. In this study, recombinant porcine beta-defensin 2 (PBD-2) was overexpressed in stably transfected PK-15(More)
Anti-microbial properties of 21 endophytic fungal strains from Hypericum perforatum Linn. were evaluated against three human pathogens, Staphyloccocus aureus, Escherichia coli and Rhodotorula glutinis, and two phytopathogens, Rhizoctonia cerealis and Pyricularia grisea. The results indicated that the ethyl acetate extracts of endophytic fermentation broth(More)
BACKGROUND A growing evidence indicates that marine sponge Phyllospongia sp. is one of rich sources of 20, 24-bishomoscalarane sesterterpenes with potent biological activities. In order to search more bioactive 20, 24-bishomoscalarane sesterterpenes for new drug discovery, chemical investigation was carried out on an Indonesian marine sponge P. papyrecea.(More)
Tobacco mosaic virus (TMV) causes significant yield loss in susceptible crops irrigated with contaminated water. However, detection of TMV in water is difficult owing to extremely low concentrations of the virus. Here, we developed a simple method for the detection and quantification of TMV in irrigation water. TMV was reliably detected at concentrations as(More)

Pharmaceutical engineering is a newly emerging interdisciplinary major in China. As a part of practice education of pharmaceutical engineering, production practice plays an important role in consolidating undergraduate's knowledge, cultivating their specialty interests and increasing their innovative ability. This paper focuses on analysis of problems in(More)
In sports training, the optical motion capture is limited by complex data processing equipment, space constraints and other issues. This paper presents a design of motion capture system based on MEMS. The system includes the target module and PC module. The former is used to collect human motion information with MEMS sensors, and uploads data to the host(More)
The data shows that about 20% of car failures come from the rear axle of the car. Accordingly we use a support vector machine based on optimization algorithm of Drosophila melanogaster as the fault diagnosis method. The vibration signal is denoised by double-tree complex wavelet transform. The feature extraction is performed by wavelet packet decomposition,(More)
