Nuclear magnetic resonance (NMR) relaxation spectrum is often used as fingerprints of molecular species, structure and dynamics in the study of complex multiphase system. Inversion algorithms such as singular value decomposition (SVD), Non-negative least square (NNLS), Solid iteration rebuild technique (SIRT) have been widely used in analyzing NMR data to obtain a T1 or T2 spectrum. However, due to the ill-conditioned nature of such inversion, it is difficult to determine the reliability of the inversion result. The concrete model is realized in MATLAB according the thought of the above three algorithms in this article. We converged to the true distribution by matching up the inversion spectrum from a series of true decay data collected from the NMR analyst instrument and a noisy simulated model, then evaluated the effects of noise in the original NMR data.

It applies hydrodynamic Model to simulate COD of sewage around Xiaoyangkou, Rudong City, Jiangsu Province in this paper. Curvilinear orthogonal grid is used in interesting area, and hydrodynamics and water quality model are used to the current velocity field and tidal level field both on case of the spring and the neap tide. The computational results are compared with measured field data around drain. It shows that the simulation results are consistent with field data. In each case of spring and neap tide , velocity and direction play an important pole in transportation and diffusion , and the effect of sewage is maximum when ebb peaks in neap tide period

As we known, now wastewater from papermaking has been the main source of water pollution in China. Polyacrylamide is one of water treatment chemicals which have been used widely. In laboratory, we prepared a novel cationic polyacrylamide (CPAM) with acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride through dispersion polymerization in aqueous solution of ammonium sulfate. Cationic polyacrylamide (CPAM) made by ourselves is with high molecular weight and high charge density, and its stability and dissolvability are both excellent. In this paper, the CPAM made by ourselves is used as flocculant cooperating with polyaluminium chloride (PAC) to treat the papermaking wastewater, the results indicate that the CPAM is an excellent flocculant for papermaking wastewater.

This work investigated the potential use of benzoic acid (BA)-based immunoadsorbent, a hydrophobic adsorbent, for autoantibodies selective adsorption therapy. The adsorbent was assessed through chromatographer and batch system assays in terms of adsorption capacity, selectivity for both polycloneantibodies in normal human plasma and pathogenic antibodies in patients' sera. For human immunoglobulin G (IgG), capacities of >30 mg/mL at 10% breakthrough (pH 7.4, linear flow rate of 212 cm/hr) were regularly achieved without adding salt. Removal percentage of immunoglobulins (Igs) in plasma samples was 34.2±±4.0%, while that of albumin was less than 3% at the ratio of 5 sample volumes per adsorbent volume. Rheumatoid factors in serum samples from 8 rheumatoid arthritis (RA) patients were eliminated at different degrees after treatment by the adsorbent. The results indicated that BA-based agrose was effective in selectively adsorbing human antibodies from plasma, could thus have a potential ability to eliminate pathogenic autoantibodies in apheresis.

Two kinds of inlin derivatives, carboxymethyl inulin (CMI) and quaternized inulin (QI), were successfully synthesized. Their structural properties were characterized by FT-IR and their moisture absorption-retention ability were explored and compared with those of hyaluronic acid (HA), respectively. Carboxymethyl and quaternary ammonium salt groups are anionic and cationic groups, which are both hydrophilic. Thereby, hydrogen bonds readily develop interactions between the derivatives' chains and water molecules. As a result, CMI and QI tended to hold more water molecules. Therefore, CMI and QI showed much stronger moisture absorption-retention ability than those of inulin. CMI should be further explored in cosmetic and clinical fields as HA substitute due to its more excellent moisture retention-absorption ability.

A delayed and stage-structured predator-prey system with Holling type-II functional response is discussed. By using the normal form theory and center manifold theorem, the linear stability of the system is investigated and Hopf bifurcations are established. Formula determining the direction of bifurcations and the stability of bifurcating periodic solutions are given. Numerical simulations are carried out to illustrate the theoretical results.

A series of orthogonal experiments were conducted to investigate the impact of ultrasound on the remediation of petroleum-contaminated soil. Five factors were examined, including initial oil concentration, soil-water ratio, soil type, sonication time and ultrasound power. The experimental results showed that the cleanup effect of ultrasound for oil contaminated soil was obvious. The soil type illustrated a significant influence on the TPH cleanup effect, while the TPH removal in four types of soils ranged from 46.7% to 83.1%. The experimental results suggested that ultrasonic desorption and subsequent filtration were the dominant mechanism for TPH reduction in the soil.
