background: application of potassium ferrate is a chemical oxidation approach used for water and wastewater treatment. the aim of this study is to apply central composite design (ccd) and response surface methodology (rsm) to optimize potassium ferrate consumption in the treatment of wastewater from carpet industries. methods: samples in this experimental study were collected from wastewater, o...
We have developed ultralow-noise electronics in combination with repetitive, nondestructive readout of a thick, fully depleted charge-coupled device (CCD) to achieve an unprecedented noise level of 0.068 e^{-} rms/pixel. This is the first time that discrete subelectron readout noise has been achieved reproducible over millions of pixels on a stable, large-area detector. This enables the contem...
Lipid nanoparticle is one of the dosage forms that have a particle size 1-100 nm. systems aggregation causes an increase in with storage time so carrier needed can reduce aggregation. The lipid system formulated gel preparations add to matrix thereby reducing Central Composite Design (CCD) part experimental design Response Surface Methodology be used determine optimization gelling agents and hu...
Article history: Received on: 05/10/2015 Revised on: 23/10/2015 Accepted on: 08/11/2015 Available online: 27/12/2015 This work, for the first time reports the optimization of recombinant human antithrombin (rhAT) production in Saccharomyces cerevisiae BY4741 using statistical experimental designs. Most applications of design of experiments (DoE) have concerned optimization of the composition of...
The noise of a digital charge coupled device (CCD) detector increases with the readout speed, causing problems in a number of important applications, such as x-ray fluoroscopy and micro-CT. In this paper, we present an approach for the design of a dual-CCD configuration to improve the average signal-to-noise ratio, and hence provide an inexpensive solution within the constraint of the current t...
Instrumentation is described that is suitable for acquiring multisource, multidetector, time-series optical data at high sampling rates (up to 150 Hz) from tissues having arbitrary geometries. The design rationale, calibration protocol, and measured performance features are given for both a currently used, CCD-camera-based instrument and a new silicon-photodiode-based system under construction....
HIV-1 integrase (IN) is essential for the integration of viral DNA into the host genome and an attractive therapeutic target for developing antiretroviral inhibitors. LEDGINs are a class of allosteric inhibitors targeting LEDGF/p75 binding site of HIV-1 IN. Yet, the detailed binding mode and allosteric inhibition mechanism of LEDGINs to HIV-1 IN is only partially understood, which hinders the s...
