    • A countercurrent system for treatment of contaminated fluid is provided. The system, in an embodiment, includes a source from which contaminated fluid may be introduced into the system and a reservoir of an adsorbent nanomaterial designed to remove contaminants from contaminated fluid. The system also includes a reactor in fluid communication with the reservoir, and within which a fluidized bed of the adsorbent nanomaterial can be accommodated in the presence of a countercurrent flow of contaminated fluid for the treatment of contaminated fluid. The system further includes a mechanism to maintain fluidity of the bed so that contaminated fluid introduced into the reactor can countercurrently flow through the bed. A pathway can also be provided along which treated fluid may be directed away from the container, as well as a collector for removing spent adsorbent material from the system. A method for treating contaminated fluid is also provided.

    • A vapor horn-packing bed assembly for a chemical process tower incorporating a plurality of directional flow vanes within a 360 degree annular housing. A structured packing bed is disposed centrally of the annular housing and the vapor horn is disposed in flow communication with the packing bed wherein discharged vapor will ascend therethrough. The vapor horn includes a plurality of equally spaced flow vanes positioned for intercepting and diverting the vapor flow downwardly within the tower for generating a substantially homogenous vapor region beneath the packing bed. The homogenous vapor generated by such a vapor horn will comprise a turbulent, gaseous region having sufficiently uniform kinetic energy to present a substantially even ascension front into the packing bed of the vapor horn assembly and other packing beds thereabove.

    • The present invention provides methods, a system, and a program product for the rapid detection and correction of spherical aberration in microscopy systems. More specifically, the present invention empirically derives a pupil function, adaptively corrects PSF parameters, and automatically detects the coefficient for spherical aberration. A first aspect of the invention provides a method for detecting and estimating spherical aberration in an acquired image obtained using an optical system, comprising the steps of deconvolving an image using each of a plurality of point spread functions, wherein each point spread function has a different spherical aberration value, calculating an image energy for each deconvolved image, and choosing as a spherical aberration coefficient the spherical aberration value corresponding to the deconvolved image having the lowest image energy, wherein a spherical aberration coefficient other than 0 indicates the presence of spherical aberration in the acquired image and its distance from 0 is an estimation of the degree and direction of spherical aberration.

    • A radiation therapy apparatus includes a multi-leaf attenuator having a first plurality of radiation attenuating leaves and a second plurality of radiation attenuating leaves. The first plurality of leaves is spaced with gaps between adjacent leaves within a radiation beam so that the leaves and the gaps therebetween divide the radiation beam into rays. The second plurality of leaves is disposed directly under gaps in the first plurality of leaves so that each ray of the beam can be occluded by a leaf in either the first or second plurality. The gaps eliminate interference between leaves; the staggering prevents radiation leakage between leaves. Each leaf, in both groups, may be moved between a first open state on one side of the beam, a closed state within the beam thus occluding one ray of the beam, and a second open state on the other side of the beam. By controlling the duty cycle of the leaves between the open and closed states, each ray of the beam may be effectively and individually attenuated over a range of intensities. Attenuating the motion between two open states provides more even radiation exposure.
    • 放射治疗装置包括具有第一多个辐射衰减叶片和第二多个辐射衰减叶片的多叶衰减器。 第一组多个叶片与辐射束内的相邻叶片之间的间隙间隔开,使得叶片和其间的间隙将辐射束分成射线。 第二多个叶片直接设置在第一多个叶片中的间隙下方,使得束的每个射线可以被第一或第二多个叶片中的叶片遮挡。 差距消除叶间的干扰; 惊人的防止叶片之间的辐射泄漏。 两组中的每个叶片可以在梁的一侧上的第一打开状态之间移动,光束内的闭合状态,从而遮挡一束光束,在光束的另一侧上移动第二打开状态。 通过控制叶片在打开和关闭状态之间的占空比,梁的每个射线可以在强度范围内被有效且单独衰减。 衰减两个开放状态之间的运动提供了更均匀的辐射照射。
