Abstract: A pilot study of the treatment for laundry wastewater recycling and reuse on the spot was carried out by ultrafiltration (UF) with different membrane material of PAN, PS and PP. According to the analysis of membrane fouling combined with UF effluent quality, PAN membrane was superior to the others. It removed the turbidity, suspended solid, fat oil and grease effectively, but kept anionic surfactant (LAS) to a certain degree in the UF effluent which is beneficial to recycling and reuse. By correlation analysis, it was found the high COD concentration of effluent was caused by LAS remained. The whiteness and softness of cotton cloth washed by UF effluent for a long-term was not different with that washed by tap water. The removal of bacteria and E. coli by UF membrane was not very high, and so UF effluent was disinfected by ultraviolet (UV) further. As the dosage of UV was not less than 3 750 J/m2, the microbial level reached the China national standard of drinking water. The optimal UF operation condition is to backwash two minutes every thirty minutes' filtration. Adopted alkali liquor of pH 11 to 13 to carry out chemical cleaning, the membrane flux was recovered completely.
Coherence generation and population transfer in a three-level ladder system

Abstract: This work explores the effect of spontaneous emission on coherence generation and population transfer in a three-level ladder atomic system driven by two pulses in counterintuitive order. With adiabatic evolution and the weak-dephasing approximation, we find that a large coherence and population transfer can be achieved even with spontaneous decay rate. The maximum coherence and population transfer decrease with the increase of spontaneous decay rate from the highest state to intermediate state. But this effect can be compensated by shortening the pulse width and enlarging the delay time. Results show that the coherence generation and population transfer never depend on the spontaneous decay rate from the intermediate state to ground state. The validity of the analytic solution is examined by numerical calculation.

LIU Fei-Fei,SHAN Jin-Hui,JIANG Ying,

计算机科学 , 2005,
Abstract: Software testing is an important part in the domain of software engineering. With the enlargement of soft- ware scale, software testing becomes more complex. The improvement of software testability is an efficient method to reduce the testing complexity. The precise measurement of software testability is the first step to achieve the above goal. Besides as a quantified guideline, the measurement result should be direction for the improvement of software testability and be helpful to testing design. In this paper, the existing analysis methods of software testability are classified roughly as analysis based on software complexity, analysis based on information theory, analysis based on PIE technology and analysis based on UML class graph. This paper briefly introduces some representative methods of each class, compares the merits and demerits of these methods. Finally, future research directions are discussed.
Effect of a barrier potential on soliton dynamical characteristics in condensates

Li Jin-Hui,

中国物理 B , 2010,
Abstract: By using the multiple-scale method, this paper analytically studies the effect of a barrier potential on the dynamical characteristics of the soliton in Bose--Einstein condensates. It is shown that a stable soliton is exhibited at the top of the barrier potential and the region of the absence of the barrier potential. Meanwhile, it is found that the height of the barrier potential has an important effect on the dark soliton dynamical characteristics in the condensates. With the increase of height of the barrier potential, the amplitude of the dark soliton becomes smaller, its width is narrower, and the soliton propagates more slowly.

Abstract: Silicate glass of system SiO2-B2O3-Al2O3-R ˉO-R2O£¨R ˉ=Ca, Mg; R=Na, K£ was designed and melted for ion-exchanged integrated optical waveguide chip, on consideration of the suitability of ion-exchange and ion-diffusion process on this glass substrate, buried channel waveguide was manufactured by Ag+/Na+ ion-exchange in mixed melted salts, and subsequently field-assisted ion-diffusion process. Observation of optical microscope and electron microprobe show that Ag+ diffusion zone is driven to approximately 10| under the glass substrate surface. The Ag+ diffusion zone possesses higher refractive index than glass substrate, and thus acts as the waveguide core. This waveguide core is typically in dimension of 8| | , matching well with that of single-mode-fiber core, which ensures a low coupling loss. Propagation loss and coupling loss with single-mode-fiber is measured to be 0.1dB/cm and 0.2-0.3dB/facet respectively, at the wavelength of 1.55| . The propagation loss is very close to glass material inhere loss at the same wavelength, a typical characteristics of buried waveguide. It shows that the waveguide manufacturing process is promising for implementation of low-loss integrated optical devices.

Abstract: Effects and underlying molecular mechanisms of IL-17 on human HCC were explored in vitro using exogenous IL-17 stimulation and in nude mice by implanting IL-17 overexpressed HCC cells. The clinical significance of IL-17 was investigated in tissue microarrays containing HCC tissues from 323 patients following hepatectomy using immunohistochemistry.Although exogenous IL-17 showed no direct effect on the growth rate of HCC cells in vitro, PCR and ELISA showed that IL-17 selectively augmented the secretion of diverse proinvasive factors and transwell showed a direct promotion of invasion of HCC cells by IL-17. Furthermore, transfection of IL-17 into HCC cells significantly promoted neoangiogenesis, neutrophil recruitment and tumor growth in vivo. Using siRNA mediated knockdown of AKT and STAT3, we suggested that the effects of IL-17 were operated through activation of the AKT signaling in HCC, which resulted in IL-6 production. Then, IL-6 in turn activated JAK2/STAT3 signaling and subsequently up-regulated its downstream targets IL-8, MMP2, and VEGF. Supporting these findings, in human HCC tissues, immunostaining indicated that IL-17 expression was significantly and positively associated with STAT3 phosphorylation, neutrophil infiltration and increased tumor vascularity. The clinical significance of IL-17 was authenticated by revealing that the combination of intratumoral IL-17+ cells and phospho-STAT3 served as a better prognosticator for postoperative tumor recurrence than either marker alone.IL-17 mediated tumor-promoting role involves a direct effect on HCC cells through IL-6/JAK2/STAT3 induction by activating the AKT pathway.Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third most common cause of cancer-related death globally [1]. Despite advances in treatment modalities, long-term survival of HCC patients remains unsatisfactory because of the high rate of recurrence and metastasis [1]. HCC is usually secondary to inflammatory conditions du

Abstract: The present study was conducted to investigate the relationship between the anti-stress and hepato-protective effects of Schisandra Lignans Extract (SLE) on stress-induced liver damage. Seven weeks old male mice were fixed in a restraint tube for 18 h to induce liver damage. SLE was orally administered to animals for 5 days at dosages of 100 and 200 mg/kg/day before exposed to restraint stress. Oral administration of SLE significantly reduced restraint-induced liver damage in experimental animal. SLE was further found to significantly alleviate the provocation of corticosterone in stressed mice. SLE also significantly decreased oxidative damage and increased anti-oxidative capability of liver cells by preventing the over production and accumulation of free radicals. In conclusion, the protective effects of SLE on stress-induced liver damage were confirmed, and the correlation between hepatoprotective and anti-stress effects of schisandra lignans was possible related to its alleviation on the malignant effects of stressors for bio-homeostasis, such as balance of oxidation and reduction in cells.

Abstract: Aims Plants show phenotypic plasticity in response to changing environments via variations of morphological and ecophysiological traits, and this plasticity can increase invasiveness. Plasticity, rather than genetic diversity, made Alternanthera philoxeroides more invasive, but its plasticity to sediment phosphorus concentration of invaded habitats was undocumented. This study addresses plasticity of A. philoxeroides to sediment phosphorus concentration and planting density and whether plasticity increases invasiveness. Methods In a controlled factorial experiment, we grew artificial populations of A. philoxeroides at low and high densities (four and eight individuals per container, respectively) under three levels (low, median, high) of sediment phosphorus concentrations. All plants were harvested after six weeks, and dry mass of leaves, stems and roots were measured. Important findings Under low planting density, leaf mass and number, stem mass and length, branch number, and total biomass of A. philoxeroides were larger at high than low or median sediment phosphorus concentration. Under high planting density, leaf number, stem length and special stem length were greater at high than at low or median sediment phosphorus concentration. Leaf, stem, root and total phosphorus concentrations in A. philoxeroides increased significantly with increasing the sediment phosphorus concentration. Leaf mass ratio was also affected by sediment phosphorus concentration, and stem mass, special stem length, leaf and total phosphorus concentration were significantly affected by planting density. Results imply that morphological and ecophysiological traits of A. philoxeroides were altered by sediment phosphorus concentration and that high sediment phosphorus may strengthen the invasiveness of A. philoxeroides.

Abstract: Aims Trapa bicornis is a clonal floating macrophyte that dominates several lakes in China. Due to eutrophication, the distribution of T. bicornis is shrinking, and T. bicornis has disappeared in some lakes. Our objectives were to investigate the effects of sediment phosphorus concentration (SP), plant density (PD) and their interaction on the plasticity of T. bicornis and examine whether plasticity could promote ecological adaptation in eutrophic environments. Methods In a controlled factorial experiment, we grew artificial populations of T. bicornis in low, medium and high PD (4, 8 and 12 individuals per container, respectively) under low, medium and high SP. We harvested all plants after six weeks and measured the dry mass for each plant part. Important findings SP significantly affected leaf, stem, green root, anchoring root and total plant phosphorus concentrations as well as number of main rosettes of trullate floating leaves, special green root length and special anchoring root length of T. bicornis, but PD did not significantly affect any growth or ecophysiological traits. With increasing SP, plant phosphorus concentration increased. Number of main rosettes of trullate floating leaves of T. bicornis was the largest at low SP and low PD, leaf mass ratio at medium SP and high PD, special green root length at high SP and medium PD, and special anchoring root length at high SP and high PD. SP, PD and their interaction altered some of the allometric relationships between leaf, stem, green root, anchoring root and total biomass. Morphological and ecophysiological traits mostly affected by SP and high PD may increase the ecological adaptability of T. bicornis under eutrophic conditions caused mainly by phosphorus.
