C-DUNFORD INTEGRAL AND C-PETTIS INTEGRAL
Da fang Zhao,Xue xiao You 충청수학회 2008 충청수학회지 Vol.21 No.1
In this paper, we give the Riemann-type extensions of Dunford integral and Pettis integral, C-Dunford integral and CPettis integral. We prove that a function f is C-Dunford integrable if and only if xf is C-integrable for each x 2 X and prove the controlled convergence theorem for the C-Pettis integral.
ON STRONG C-INTEGRAL OF BANACH-VALUED FUNCTIONS
Da fang Zhao,Guo ju Ye 충청수학회 2007 충청수학회지 Vol.20 No.1
In this paper, we de¯ne and study the Banach-valued C-integral and strong C-integral, We prove that the C-integral and the strong C-integral are equivalent if and only if the Banach space is ¯nite dimensional. We also study the primitive of the strong C-integral in terms of the C-variational measures.

The mature landfill leachate, which is characterized by a high concentration of ammonia nitrogen (NH3-N) and humic acid (HA), poses a challenge to biotreatment methods, due to the constituent toxicity and low biodegradable fraction of the organics. In this study, we applied bioaugmentation technology in landfill leachate degradation by introducing a domesticated NH3-N and HA resistant bacteria strain, which was identified as Bacillus cereus (abbreviated as B. cereus Jlu) and Enterococcus casseliflavus (abbreviated as E. casseliflavus Jlu), respectively. The isolated strains exhibited excellent tolerant ability for NH3-N and HA and they could also greatly improved the COD (chemical oxygen demand), NH3-N and HA removal rate, and efficiency of bioaugmentation degradation of landfill leachate. Only 3 days was required for the domesticated bacteria to remove about 70.0% COD, compared with 9 days`` degradation for the undomesticated (autochthonous) bacteria to obtain a similar removal rate. An orthogonal array was then used to further improve the COD and NH3-N removal rate. Under the optimum condition, the COD removal rate in leachate by using E. casseliflavus Jlu and B. cereus Jlu increased to 86.0% and 90.0%, respectively after, 2 days of degradation. The simultaneous removal of NH3-N and HA with more than 50% and 40% removal rate in leachate by employing the sole screened strain was first observed.

We study the off-equilibrium effects of the in aton field on the dynamics of primordial perturbations in the O(N) model. A self-consistent off-equilibrium formalism is employed to investigate the evolution of the in ationary background eld and its uctuations with the back-reaction effects. We nd two observable remains left behind after the off-equilibrium processes: the running spectral index of primordial density perturbations and the correlations between perturbation modes in phase space, which can serve as the imprints to probe the epoch of in ation, and beyond.

Herein, a series of lasiokaurin derivatives were designed and synthesized. All the derivatives together with lasiokaurin and oridonin were tested for their antimicrobial and antiproliferative activity. Compound 16 showed the most promising antimicrobial activity with MICs of 2.0 and 1.0 lg/mL against Gram-Positive bacteria S. aureus and B. subtilis, respectively. All the synthetic lasiokaurin derivatives showed better antiproliferative activity than parent compound lasiokaurin 1. Compound 10 exhibited the strongest cytotoxicity with IC50 values of 0.47 and 0.20 lM against MGC-803 and CaEs-17 cells, accordingly. Moreover, it was shown to have potent antitumor activity in vivo in a murine model of MGC-803 gastric cancer. Preliminary SARs were also concluded based on obtained data. The apoptosis-inducing effects of 10 were further investigated using CaEs-17 cells. The results showed that lasiokaurin derivative 10 could induce apoptosis via mitochondria related pathway and arrest CaEs-17 cell cycle at S phase. Compound 10 could also affect apoptosisrelated proteins that was up-regulation of CDK2 and downregulation of ATM and cyclin A1.
