The strong interaction in a radial pump due to the relative movement between the impeller and the diffuser may excite not only strong pressure fluctuations but also velocity fluctuations. In this paper, the laser Doppler velocimetry （LDV） technique is successfully applied to measure the periodic flow field in a radial diffuser pump with low-specific speed, in order to investigate the velocity fluctuations caused by the impeller-diffuser interactions both in the impeller and diffuser regions. The velocity fluctuations in the impeller region are quantitatively examined at different radial positions, and the flow structure at the radial gap between two flow components is analyzed at different relative positions. In addition, the downstream effect on the diffuser flow is quantitatively and qualitatively assessed and compared with the turbulence effect.

The equation of state for nuclear matter is presented within the Brueckner Hartree-Fock （BHF） scheme, by using the realistic Argonne VI8 or Bonn B two-nucleon potentials plus their corresponding microscopic three-nucleon forces. It is then applied to calculate the properties of finite nuclei within a simple liquid-drop model, and we compare the calculated volume, surface, and Coulomb parameters with the empirical ones from the liquid drop model. Nuclear density distributions and charge radii in good agreement with the experimental data are obtained~ and we predict the neutron skin thickness of various nuclei.

With the complementarity of the nucleonic three-body force,we present the saturation points of symmetric nuclear matter with different interactions adopted within the Brueckner-Hartree-Fock scheme,and a more accurate empirical parameterization function for the equation of state of symmetric nuclear matter and pure neutron *** the basis of this fit formula,the symmetry energy and its derivatives are investigated,and ultimately the higher-order coefficient of the isobaric incompressibility for isospin asymmetric nuclear matter is predicted.

In this paper, the author refers to the Latin translation of the Kitab Ihsa ＇al＇ Ulum of Al-Frabi made by Dominicus Gundissalinus in the Xllth Century in Toledo, Spain. This text under the Latin title De scientiis was one of the most influential texts of the Arab and Persian world in the western Latin Europe. It is an introductory text into all until known sciences written for students and laymen （illiterate） who want to study one of these sciences. The text of Al-Farabi discusses the seven liberal arts, all of the works on physics of Aristotle and includes some reflexions on metaphysics, political philosophy and theology. There are two important points：（1） All sciences have a theoretical and practical aspect. All sciences are sciences of principles and causes and their application to the practical world. （2） The so called prima philosophia is the political philosophy and not metaphysics. In this respect, Al-Farabi subordinates theology as a science of the religious laws to politics as a science of civil laws. In the same respect, he combines, under the famous sentence of Plato that philosophers are the governors and the very well companions of mankind, politics with theology

Cabbage root fly （Delia radicum L.） control represents a major challenge in brassica production, therefore different management strategies for its control were tested in conventionally managed open field cauliflower production. Strategies included treatments with low-risk methods such as nitrogen lime, the insecticide spinosad and the Beauveria bassiana ATCC 74040-based biopesticide Naturalis. Their effects were compared with treatments based on nonformulated fungal species Metarhizium brunneum, B. bassiana, Clonostachys solani, Trichoderma atroviride, T. koningiopsis, and T. gamsii and commercial insecticides λ-cyhalothrin and thiamethoxam. Spinosad and thiamethoxam were pipetted to individual plants before transplanting; λ-cyhalothrin was sprayed after transplanting; nitrogen lime was applied at first hoeing. Nonformulated fimgi were delivered onto cauliflower plantlets＇ roots as a single pretransplantation inoculation. The cabbage root fly population dynamics exhibited a strong spatiotemporal variation. The lowest number of cabbage root fly pupae recovered from cauliflower roots in the field experiments was recorded in plants treated with spinosad （significant reduction）, followed by Naturalis and one of the tested M. brunneurn strains （nonsignificant reduction）. Significantly more pupae were counted in the nitrogen lime treatment. The field experiments showed that a single drench of cauliflower plantlets with spinosad offered consistent and enduring cabbage root fly control. Naturalis and nonformulated fungal isolates did not decrease cabbage root fly pressure significantly, apparently due to lack of statistical power. The implications of the substantial intra- and inter-annual pest pressure variation and the benefits of using single plant treatments are discussed, and recommendations for improvement of rhizosphere-competence utilizing biological control strategies provided.

AIM： To evaluate the mechanism underlying the effects of 5-Fluorouracil （5-FU） on adenoviral infection. METHODS： Low and high Coxsackievirus-Adenovirus Receptor （CAR） expressing human colon carcinoma cell lines were treated with 5-FU and two El-deleted adenoviral constructs, one transferring GFP （Ad/CMV- GFP） the other bax （Ad/CEA-bax）. The number of infected cells were monitored by GFP expression. To evaluate the effects of 5-FU in a receptor free system, Ad/GFP were encapsulated in liposomes and treated with 5-FU. Ad/GFP release was estimated with PCR and infection of 293 cells with the supernatant. Electron microscopy of the Ad5-GFP-liposome complex was made to investigate morphological changes of the liposomes after 5-FU. RESULTS： Infection rates of all cell lines increased from 50% to 98% with emerging 5-FU concentrations. The enhanced viral uptake was independent of the CAR expression. Additionally, 5-FU treated liposomes released 2-2.5 times more adenoviruses. Furthermore, 5-FU- treated liposomes appeared irregular and porous-like. CONCLUSION： adenoviral uptake is enhanced in the presence of 5-FU irrespective of CAR and is associated with morphological changes in membranes making the combination of both a promising option in gene therapy.
