In this study, we have investigated variations in the potential of floating and submerged leaves of longleaf pondweed (Potamogeton nodosus) to withstand silver ion (Ag+)-toxicity. Both floating and submerged leaves changed clear colorless AgNO3 solutions to colloidal brown in the presence of light. Transmission electron microscopy revealed the presence of distinct crystalline Ag-nanoparticles (...

Trabecular bone disconnection “hotspots” of real termini (ReTm) previously mapped as loci weakness in the female aging spine and hip may be a source free-floating cancellous segments found medullary space using bespoke, thick slice histological method for identifying ReTm. A factor their origin is apparently microdamage proliferation (differentiated by en bloc silver staining) with occasional c...

The aim of the present study was to prepare and evaluate floating microspheres consisting of (i) calcium silicate (CS) as porous carrier; (ii) amoxicillin and (iii) hydroxypropyl methylcellulose (HPMC) and ethylcellulose (EC) as polymers. The floating microspheres were evaluated for particle size, micromeritic properties, percent drug content, in vitro floating behavior, and in vitro drug relea...

This paper describes a method for customising the representation of floating-point numbers that exploits the flexibility of reconfigurable hardware. The method determines the appropriate size of mantissa and exponent for each operation in a design, so that a cost function with a given error specification for the output relative to a reference representation can be satisfied. Currently our tool,...

PURPOSE To evaluate the variation in higher-order ocular wavefront aberrations and the Nyquist limit of resolution of the cone mosaic (N(c)) in a population of young healthy subjects and the relation to axial length (AL). SETTING Fondazione G.B. Bietti IRCCS, Rome, Italy. DESIGN Case series. METHODS An adaptive optics retinal camera prototype (rtx1) was used to image the cone mosaic. Cone...

background: floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. this study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed. materials and meth...

A tone mapping operation (TMO) for HDR images with fixed-point arithmetic is proposed. A TMO generates a low dynamic range (LDR) image from a high dynamic range (HDR) image by compressing its dynamic range. Since HDR images are generally expressed in a floating-point data format, a TMO also deals with floating-point data even though resulting LDR images have integer data. As a result, conventio...

We develop an active set method for solving second-order cone programs that may have an arbitrary number of linear constraints but are restricted to have only one second-order cone constraint. Problems of this form arise in the context of robust optimization and trust region methods. The proposed active set method exploits the fact that a second-order cone program with only one second-order con...
