FULL-SCALE DEMONSTRATION OF IMPROVEMENT IN AERATION EFFICIENCY
James A. Mueller,Kim, Yeong-Kwan,Joseph J. Krupa,Frank Shkreli,Sami Nasr,Brian Fitzpatrick 江原大學校 附設 環境硏究所 2000 環境硏究 Vol.17 No.-
This paper describes the results of side-by side full-scale aeration testing of a plug-flow process and a modified contact stabilization process incorporating an anaerobic selector at the wastewater treatment facility in Fredonia, N.Y. Over 40 tests were completed utilizing the off-gas technique during the 2-month investigation period (summer of 1995). Compared to the plug-flow process, the modified contact stabilization process with internal sludge recycle was shown to have higher ? values and to require less blower energy consumption when the selector operation was properly controlled. Dissolved oxygen concentration, selector COD concentration, and internal recycle sludge levels were found to be critical parameters in the successful operation of the modified process. Higher internal recycle sludge levels allosed the plant to run at more stable operating conditions in terms of the oxygen transfer efficiency, ?, and sludge volume index.

Next generation sequencing technologies have accelerated the rate at which whole genome sequencing (WGS) data is acquired. The sheer volume of data generated by WGS requires computational annotation to define potential coding regions and chromosomal features. The accuracy of genomic annotation is thus limited by the power of the computational algorithm and the sequence coverage provided by the raw data. Sequencing of the New Zealand White (NZW) rabbit has been performed to a 7× depth of coverage, leaving large gaps in coverage and potential errors within the draft assembly. In the present study, we have resequenced the collagen type I, alpha 1 (Col1A1) gene of Oryctolagus cuniculus (n = 8). We have characterized the full length cDNA, identified splicing errors within the reference sequence, and identified single nucleotide polymorphisms within the gene. These data underscore the need for a higher resolution assembly of the rabbit genome to advance research in this important large animal model.

Background/Objectives: The Philippine government through the Department of Science and Technology (DOST) helps the micro, small, and medium enterprises (MSMEs) to support and sustain growth and address their needs on availing cost-effective solutions. Methods/Statistical analysis: Most of the MSMEs which apply clear bottles for their products use manual inspection. These are prone to human error that leads to poor product qualities and rejects. Findings: To address these problems, this study presents a cost-effective solution by a rule-based machine vision system for clear empty glass base inspection. A method on proper setup for the inspection is presented and validated through an in-line loop on a wedge conveyor machine prototype. A minimal setup time was achieved by experimenting different lighting techniques. Improvements/Applications: The use of back light illumination is suggested for good image processing quality with minimal cost. The implementation of a rule-based inspection in this setup results to a high speed of 9000-18000 bottles per hour (bph) with consistent repeatability and superior accuracy.
Threshold Voltage Control through Layer Doping of Double Gate MOSFETs
Saji Joseph,George James T,Vincent Mathew 대한전자공학회 2010 Journal of semiconductor technology and science Vol.10 No.3
Double Gate MOSFETs (DG MOSFETs) with doping in one or two thin layers of an o therwise intrinsic channel are simulated to obtain the transport characteristics, threshold voltage and leakage current. Two different device structures- one with doping on two layers near the top and bottom oxide layers and another with doping on a single layer at the centre- are simulated and the variation of device parameters with a change in doping concentration and doping layer thickness is studied. It is observed that an n-doped layer in the channel reduces the threshold voltage and increases the drive current, when compared with a device of undoped channel. The reduction in the threshold voltage and increase in the drain current are found to increase with the thickness and the level of doping of the layer. The leakage current is larger than that of an undoped channel, but less than that of a uniformly doped channel. For a channel with p-doped layer, the threshold voltage increases with the level of doping and the thickness of the layer, accompanied with a reduction in drain current. The devices with doped middle layers and doped gate layers show almost identical behavior, apart from the slight difference in the drive current. The doping level and the thickness of the layers can be used as a tool to adjust the threshold voltage of the device indicating the possibility of easy fabrication of ICs having FETs of different threshold voltages, and the rest of the channel, being intrinsic having high mobility, serves to maintain high drive current in comparison with a fully doped channel.
