Selecting appropriate learning services for a learner from the large number of heterogeneous knowledge sources is a complex and challenge task. This paper illustrates and discusses how semantic Web technologies such as RDF and ontology can be applied to e-learning system for helping learners select suitable learning course or retrieving relevant(More)
Forecasting has been playing an important role in many industries such as marketing, financial planning, and production control. This paper firstly gives a brief review of time series forecasting techniques, particularly covers moving averages model and exponential smoothing mode. We, then applies an illustrative example to these techniques with actual data(More)
OBJECTIVE To investigate the expression of the interferon-induced transmembrane-1 (IFITM1) gene in colorectal cancer (CRC) tissue and the serum anti-IFITM1 antibody responses of the patients and assess their value in clinical diagnosis of CRC. METHODS Semi-quantitative RT-PCR was performed to detect IFITM1 mRNA expression in the specimens of normal(More)
The indium tin oxide(ITO) glass was applied as the electrode to study the electrochemilumuinescent behavior of luminol on its surface. The experimental results indicated that it was an excellent electrode material for ECL of luminol with very high sensitivity. The detection limit of the luminol is as low as 10(-15) mol x L(-1) order of magnitude. Compared(More)
OBJECTIVE To study the effect of potassium level on physiological characteristics and diosgenin content of Dioscorea zingiberensisg and provide experimental basis for proper use of potassium fertilizer. METHODS Field experiment including four potassium levels was carried out. The physiological characteristics of leaves were determined at different growth(More)
The present paper reports the researches on sensitization of nano-bimetalic material for the electrochemiluminescence (ECL) of luminol. The platinum-gold bimetallic nanoparticles with different component ratio and size were prepared by chemical reduction. The analytical methods such as UV-Vis spectra, TEM and XRD were applied to characterize the properties(More)
OBJECTIVE To screen and identify the genes coding for colorectal carcinoma-associated antigen and analyze the bioinformation of their cDNA sequences. METHODS Immunoscreening of the cDNA phage-display library derived from human colorectal carcinoma was performed with autologous or allogeneic serum antibody from patients with colorectal cancer through SEREX(More)
OBJECTIVE To study the PCR amplification, cloning and protein expression of interferon-inducible transmembrane protein-1 (IFITMP-1) gene. METHODS With the cDNA fragment containing IFITMP-1 gene as template, IFITMP-1 gene was amplified using Pfu enzyme by means of PCR. After EcoRI and HindIII digestion, the target gene fragment was linked to pUCm-T plasmid(More)
