In data-based monitoring field, the nonlinear iterative partial least squares procedure has been a useful tool for process data modeling, which is also the foundation of projection to latent structures (PLS) models. To describe the dynamic processes properly, a dynamic PLS algorithm is proposed in this paper for dynamic process modeling, which captures the(More)
OBJECTIVE To study the effect of copper deficiency on the nutritional status of iron, the expression of hepcidin mRNA and transferrin receptor mRNA in rats. METHODS Forty eight clean male SD rats were randomly divided into four groups according to body weight; and there were 12 rats in each group. The groups are normal iron and copper control group (group(More)
We studied the combination between seven kinds of drugs and the bovine serum albumin (BSA) using Methyl Green (MG) as fluorescent probe. These drugs were Streptomycin sulphate, Kanamycin sulfate, Gentamicin, Amikacin, Neomycin, Thiamphenicol and Florfenicol. And after reaction of these drugs, the fluorescence intensity of BSA had no obvious change. Research(More)
The antibacterial activity of antimicrobial peptides produced by strain LFB 112 was determined using the cup-plate method and a standard curve of penicillin. An effective method to evaluate the antimicrobial activity of antibacterial peptides was established. Three active fractions, Fraction A (5.0–5.5 kDa), Fraction B (3.0–3.5 kDa) and Fraction C (400–800(More)
The reaction mechanism of cefpirome sulfate with lysozyme at different temperatures (298, 310 and 318 K) was investigated using fluorescence quenching and synchronous fluorescence spectroscopy under simulated physiological conditions. The results clearly demonstrated that cefpirome sulfate caused strong quenching of the fluorescence of lysozyme by a static(More)
OBJECTIVE To study the effect of iron deficiency on vitamin A (VA) metabolism in rats. METHODS Forty-four male SD rats were divided randomly into four groups according to their body weights and every group included 11 rats: control group (I group), entire iron deficient and normal VA group (II group), slight iron deficient and normal VA group (III group),(More)
A quantitative method was developed for the determination of proteins in aqueous solution. Under optimal conditions, the linear ranges of calibration curves for the determination of bovine serum albumin (BSA), human serum albumin (HSA) and egg albumin (Alb) were 01.13 μg ml-1, 0-1.17μg ml-1 and 0-1.13μg ml-1, respectively. The detection limits were 15.74 ng(More)
Interaction mechanism of cefoperazone sodium (CFP) and ofloxacin (OFX) with bovine serum albumin (BSA) at different temperatures by fluorescence spectrometry method was studied. Results showed that CFP or OFX could quench the fluorescence of BSA. The fluorescence would quench to a larger degree when OFX (or CFP) was added to the system of BSA-CFP (or(More)
Introduced in great detail about the principle of main circuit, sampling circuit, control circuit, drive circuit and protect circuit. Then the specific implementation steps of photovoltaic inverter system were given which based on TI company's digital signal processor (DSP)TMS320F2812. Described the method of selecting components. The DC/DC and DC/AC two(More)
