An aqueous solution of boric acid, as an efficient and green catalytic system, was efficiently utilized four-component cascade reaction of aryl aldehydes, dimedone, β-ketoesters and ammonium acetate to give hexahydroquinolines. By the reaction of boric acid with water, H+ was generated and efficiently catalyzed the reaction under mild and green condition. Also, optimization of the reaction cond...

In the past twenty years, CCD sensor technology has made significant progress in increasing resolution and improving low-light performance by hardware. However due to physical limits of the sensor design and fabrication, fill factor has become the bottle neck problem for improving quantum efficiency of CCD sensor in order to widen dynamic range of output image. In this paper we propose a novel ...

In conventional confocal microscopy, a physical pinhole is placed at the image plane prior to the detector to limit the observation volume. In this work, we present a modular design of a scanning confocal microscope which uses a CCD camera to replace the physical pinhole for materials science applications. Experimental scans were performed on a microscope resolution target, a semiconductor chip...

We present a realtime and reliable continuous collision detection (CCD) algorithm between triangulated models that exploits the floating point hardware capability of current CPUs and GPUs. Our formulation is based on Bernstein Sign Classification that takes advantage of the geometry properties of Bernstein basis and Bézier curves to perform Boolean collision queries. We derive tight numerical e...

Central composite discrepancy (CCD) has been proposed to measure the uniformity of a design over irregular experimental region. However, how CCD-based optimal uniform designs can be efficiently computed remains a challenge. Focusing on this issue, we proposed a particle swarm optimization-based algorithm to efficiently find optimal uniform designs with respect to the CCD criterion. Parallel com...

Aims: Circumcision is a minor urologic surgery that is widely used in Iran and other Muslim and non-muslin countries. A common complication following this procedure is bleeding. The aim of this study was to compare compressive dressing with no dressing and conventional dressing options for circumcision in point of bleeding after circumcision. Materials & Methods: Between October 2010 and July ...

We have designed, constructed and put into operation a large area CCD camera that covers a large fraction of the image plane of the 1 meter Schmidt telescope at Llano del Hato in Venezuela. The camera consists of 16 CCD devices arranged in a 4 × 4 mosaic covering 2.3 × 3.5 of sky. The CCDs are 2048 × 2048 LORAL devices with 15μm pixels. The camera is optimized for drift scan photometry and obje...

This study was designed to determine the effects of parameters: temperature, pH and dKH on growth indices of Oscar fish (Astronotus ocellatus). For this purpose, in each aquarium, there was specific combinations of temperature, pH and dKH, using design of experiment with Design Expert 7.0, and in total 14 combinations or treatments, each with 3 repetitions and thus, 3 fishes were entered in eac...

In this study, biodiesel was produced from underutilized kariya oilseed using ethanol in the presence of pod-husks bio-catalyst. The oil used extracted through soxhlet solvent extraction approach. Transesterification seed investigated Central Composite Design (CCD) Response surface methodology. Process factors such as reaction temperature (65, 70, and 85oC), time (2, 3, 4 h), ethanol/kariya mol...
