Abstract: Provided are partially and fully earth-anchored cable-stayed bridges, each of which uses a prestressing unit including anchor units and a prestressing member from deck segments installed at its main span such that the prestressing unit serves as a conventional windproof cable and can simultaneously introduce a tensile stress. Thereby, a magnitude of the maximum compressive stress acting on a cross section of each main-span deck segment is reduced, so that it is possible to reduce a cross-sectional area of each main-span deck segment and thus to ensure economical construction. All or part of the compressive stress generated at the main span can be offset by the tensile stress caused by the prestressing member.

Abstract: A sound attenuating air vent comprises: an air path and a discontinuous sound absorbing lining around at least a part of the air path. A method of designing such a sound attenuating air vent comprises: determining a target attenuation performance based on the noise source and the receiver noise sensitivity and the separating construction, and determining a desired arrangement for the discontinuous lining and/or vent based on the target attenuation performance.

Abstract: Polymeric anion exchangers are used as host materials in which hydrated Fe(III) Oxides (HFO) are irreversibly dispersed within the exchanger beads. Since the anion exchangers have positively charged quaternary ammonium functional groups, anionic ligands such as arsenates, chromates, oxalates, phosphates, phthalates can permeate in and out of the gel phase and are not subjected to the Donnan exclusion effect. Consequently, anion exchanger-supported HFO micro particles exhibit significantly greater capacity to remove arsenic and other ligands in comparison with cation exchanger supports. Loading of HFO particles is carried out by preliminary loading of the anion exchange resin with an oxidizing anion such as MnO4? or OCl?, followed by passage of a Ferrous Sulfate solution through the resin.

Abstract: A method of transporting and installing an offshore structure including transporting the offshore structure to the installation site by barge with at least a portion of the structure being supported under the barge, and lowering the offshore structure to the water bed. In accordance with a preferred embodiment, the structure includes a tower and a base, with the tower being mounted offset from a center of the base through the use of bolts.

Abstract: A method for determining whether a DNA sequence is identical to a wild-type sequence is presented. A GC-rich DNA segment is attached to a DNA segment of interest. With the GC-clamp attached, the DNA segment of interest has two melting domains, a higher domain associated with the GC-clamp and a lower domain associated with the DNA segment of interest. The DNA segment of interest is labeled with a fluorescent label such as a double-stranded DNA binding dye and mixed with a denaturant. The mixture of denaturant and fluorescently labeled DNA is heated. Fluorescence is monitored to determine the melting point of the DNA segment of interest. The melting temperature of the DNA segment of interest is compared to the melting point of the wild-type sequence. A difference in melting temperatures of the DNA sequence and the wild-type sequence indicates an alteration in the DNA sequence.

Abstract: The present invention relates to a method for early prediction of a prostate cancer patient's response to hormonal treatment. In one embodiment, the method of the present invention involves assaying a body fluid, such as plasma or serum, from a prostate cancer patient for the presence of elevated levels of chromogranin A (CgA). Elevated levels of CgA may indicate neuroendocrine differentiation of cells within the prostate tumor, and may require altering the patient's treatment. In a further embodiment of the method of the present invention, periodic assays for CgA are conducted for a patient undergoing hormonal treatment for prostate cancer. The results of these assays are correlated to determine if the patient's levels of CgA are high (greater than 100 ng/mL) or increasing. Such assays may also be carried out in conjunction with assays for total prostate specific antigen (tPSA).

Abstract: A header tube for heat exchangers with a tube segment having slots which are perpendicular to the tube axis and spaced in the longitudinal direction and separated by webs, into which hollow flat pipes can be inserted and joined to the contact surface of the respective slot. The webs each have a pair of stampings to strengthen the material on each side of each web and the webs are shaped largely flat such that the cross-section of the tube segment has a largely D-shaped profile. A method of manufacturing the header tubes is also presented.
