In general, Banach space-valued Riemann integrable functions defined on [0, 1] （equipped with the Lebesgue measure. need not be weakly continuous almost everywhere. A Banach space is said to have the weak Lebesgue property if every Riemann integrable function taking values in it is weakly continuous almost everywhere. In this paper we discuss this property for the Banach space LX^1 of all Bochner integrable functions from [0, 1] to the Banach space X. We show that LX^1 has the weak Lebesgue property whenever X has the Radon-Nikodym property and X＊ is separable. This generalizes the re.ult by Chonghu Wang and Kang Wan [Rocky Mountain J. Math., 31（2）, 697-703 （2001）] that L^1[0, 1] has the weak Lebesgue property.

This paper investigates the fre. vibration and transient re.ponse of interconnected structure. including double curved beams and intermediate straight beams,which are.all constructed from functionally graded porous(FGp) materials. The strain potential and kinetic energies of each beam along with the work done by the external force are.calculated. Additionally, a higher-order beam element is introduced to derive stiffness and mass matrices, along with the force vector. The curved and straight beams are.discre.ized, and their assembled stiffness, mass matrices, and force vectors, are.*** conditions at the joints are.used to derive the total matrices of the entire.structure. subsequently, the natural fre.uencies and transient re.ponse of the system are.determined. The accuracy of the mathematical model and the self-developed computer program is validated through the comparison of the obtained re.ults with those of the existing literature.and commercial software.a.sYs, demonstrating excellent ***, a compre.ensive study is conducted to investigate the effects of various parameters on the fre. vibration and transient re.ponse of the considere. structure.

experimental data from the pep-II B-factory at 10.6 GeV center-of-mass （c.m.） energy, obtained via initial-state radiation （IsR） with the BABAR detector, are.pre.ented. The cross sections for many hadronic processes have been measure. from the production thre.hold to 4-5 GeV of the e^＋e^- c.m. energy. The obtained data allow to study a number of intermediate states and determine the parameters of known re.onances and their branching fractions. The exclusive cross section for some number of hadronic sub-processes are.pre.ented.

We studied the dynamics of mercury（Hg） transfer in phaseolus vulgaris plants grown in soil with Hg-doped compost at the maximum levels permitted by Colombian law on organic amendments. Quantitative evaluation of transfer was made in differe.t plant organs： roots,stem, leaves, pods and seeds. Matrix effect was determined in doped soil assays, using soil with and without addition of compost. re.ults showed that the use of organic matter re.uced Hg transfer to the plant and the amount transferre. was differe.tially distributed to the organs. We observed an inverse re.ationship between concentration and distance from the body to the root. It was evident that transfer was mediated by quantitative factors;the gre.ter the pre.ence of mercury in soil, the larger the amount that will be *** also indicate the re.edial effect of compost and the pre.ence of a barrier, at the root level, against mercury translocation to the plant aerial parts.
