Floor drains in processing environments harbor Listeria spp. due to continuous presence of humidity and organic substrates. Cleaning and washing activities in food-processing facilities can translocate the bacterial cells from the drain to the surrounding environment, thus contaminating food products still in production. This study evaluated the potential for translocation of Listeria monocytogenes from drains to food contact surfaces in the surrounding environment using Listeria innocua as a surrogate. A 7 × 7 × 8-foot polycarbonate flexi-glass chamber with a 10-inch-diameter drain mounted on an aluminum cabinet was used. Stainless steel coupons (6.4 × 1.9 × 0.1 cm, 12 per height) were hung at 1, 3, and 5 feet inside the chamber. Four treatment sets; non-inoculated, non-treated; non-inoculated, treated; inoculated, treated; inoculated non-treated; and two subtreatments of 8 h and 48 h were performed. For the inoculated sets, meat slurry (10 gof ground beef in 900 mL water) and a four-strain cocktail of Listeria innocua at 7 - 8 log CFU/mL were used. For the treated sets, in addition, a commercial cleaner and sanitizer was applied. The drain was cleaned using a pressure hose (40 - 50 psi) after 8 h and 48 h. Coupons were then removed and enriched in listeria enrichment broth to establish if any cell translocated from the drain onto the stainless steel coupons via aerosols generated during washing. Confirmation was done using VIP Listeria rapid test kits. Results indicated translocation at all three heights ranging from 2% - 25%. Significantly higher translocation (p < 0.05) was found at 1 foot (up to 25%), followed by 3 feet (up to 11%) and 5 feet (up to 2.7%). This research indicated that translocation of Listeria spp. from drains to food contact surfaces does occur and increases with increased proximity to the drain.

Commercially processed foods become contaminated with Listeria monocytogenes in post-processing environments where favorable conditions help the bacteria thrive. The US Food and Drug Administration has approved Lauric arginate (LAE) as generally recognized as safe (GRAS) for certain food applications. This study evaluated the efficacy of Mirenat-N (LAE dissolved in food-grade propylene glycol) against L. monocytogenes on food contact surfaces. A three-strain cocktail of L. monocytogenes was used to inoculate 24 polished stainless steel coupons with three treatments, 100 ppm and 200 ppm solutions of LAE and water (control); two sub-treatments of high (6 log CFU/ml) and low (4 log CFU/ml) inoculum levels; and two contact times of 5 and 15 min. Attached bacteria were dislodged by vortexing coupons for 1 min with 20 g of 3-mm solid glass beads in 10 ml of 0.1% peptone diluent, and bacterial populations were calculated by plating onto modified oxford medium (MOX) and thin agar layer MOX (TALMOX). The 100 ppm treatment showed average reductions of 1.38 and 2.57 log CFU/coupon at the low inoculum level and 0.37 and 0.62 log CFU/coupon at high inoculum levels, after 5 and 15 min exposure, respectively. For 200 ppm at the high inoculum level, 1.23 and 1.88 log CFU/coupon reductions were seen for 5 and 15 min, respectively; the low inoculum level at 5 and 15 min exposure showed reductions of ≤1.5 log CFU/coupon. The 100 ppm LAE treatment was more effective at low inoculum levels for 5 and 15 min contact times and may be used to control low levels of contamination of L. monocytogenes on food contact surfaces.

Open Journal of Medical Microbiology (OJMM) , 2012, DOI: 10.4236/ojmm.2012.23011
Abstract: This study was performed to evaluate the efficacy of the Demolizer? technology for the on-site sterilization of low vo-lumes of regulated medical waste. The objective was to demonstrate a minimum of 6 log10 reduction of the dry heat sterilization process applied by the Demolizer? II system for the representative organisms, Staphylococcus aureus, Escherichia coli, Candida albicans, Mycobacterium phlei and Bacillus subtilis spores (formerly Bacillus subtilis) on simulated medical waste consistent with numerous regulatory standards for medical waste treatment. The system cycle was heat treatment at a minimum temperature of 350?F and held at or above this temperature for a minimum of 90 minutes. Upon completion of treatment, there was no evidence of growth in the bacterial species after treatment. Given the minimum detection level of 4 CFU/ml, the Demolizer? II system demonstrated a minimum sterilization efficacy of 6.6 log10 for both S. aureus and E. coli as representative gram-positive and gram-negative bacteria species. Candida albicans (6.7 log10 CFU/ml), Mycobacterium phlei (9.0 log10 CFU/ml) and Bacillus subtilis (6.3 log10 CFU/ml) were completely eliminated after sterilizing representative medical waste in the Demolizer? II system for 90 minutes at a minimum temperature of 350?F. Also, the Demolizer? II exceeded typical recognized standards for medical waste treatment of a 6 log10 reduction of Mycobacteria and a 4 log10 reduction of the appropriate Bacillus endospore.

International Journal of Clean Coal and Energy (IJCCE) , 2015, DOI: 10.4236/ijcce.2015.42004
Abstract: The experimental determination of mineral matter in coal is a tedious as well as time consuming process, and requires highly skilled analyst to carry out the chemical analysis of coal and ash. On the other hand, determination of moisture and ash is relatively easy using moisture oven and muffle furnace and can be determined anywhere with little care. Most of the methods reported till date for the evaluation of mineral matter in coal involves indirect determination of mineral matter using high temperature ash as one parameter. All these methods offer conversion of ash yield into mineral matter with the help of correlations based on certain assumptions. Although, the method for direct determination of mineral matter by chemical analysis is also reported, but is of little use as it requires extensive chemical analysis. In this study mineral matter is determined directly by oxygen plasma asher in coal samples collected from different regions of India. The results obtained were compared with those obtained by existing correlations. It has been observed that all the existing correlations including Parr’s, are found to be unrealistic for high ash Indian coal. An attempt has been made to develop a new correlation for the estimation of mineral matter based on two simple parameter i.e. moisture content and ash yield. Present model was developed after analyzing 75 coal samples. The developed correlation appears to be more simple and better and is represented as Mineral Matter(MM)= 0.74(Moisture) + 1.17(Ash)

Abstract: A new technique using signal flow graph for conversion of ladder based filter into CFOA based filter has been proposed. The proposed technique converts the existing LC ladder based filter into CFOA in low pass and high pass configuration. The design of low pass filter and high pass filter has been realized using the proposed technique. The proposed configuration is implemented using CFOA as an active device and all the capacitors are grounded. Simulation has been carried out using simulation software I-cap. The simulation results have been demonstrated and discussed.
Significance of Ultra High Energy Cosmic Rays

Physics , 2011,
Abstract: The study of ultra high energy cosmic rays is a very important scientific problem. It is likely to have a huge impact in our understanding of the universe. Very high energy particles have been observed to hit the Earth whose origin is likely to be outside our Galaxy. Infact, particles with energies exceeding 10^ (20) electron volts which only hit the earth once in a century have been observed recently. The source of these high energy particles remains a deep and fascinating mystery yet to be resolved. Recently, a huge detector 30 times the size of the city of Paris is built by Pierre Auger Observatory to study these high energy particles. These detectors use the properties of Cherenkov radiation to identify the particles. Firstly, the paper will briefly explain the scientific motivation behind studying ultra high energy cosmic rays. Secondly, this paper will try to explain the reasons behind using water Cherenkov detectors. Thirdly, the paper within its limited scope, will try to give an overview of the exact process by which ultrahigh energy cosmic rays are detected using surface and water Cherenkov detectors.
Physical Scaling Limits of FinFET Structure: A Simulation Study
Gaurav Saini,Ashwani K Rana
International Journal of VLSI Design & Communication Systems , 2011,
Abstract: In this work an attempt has been made to analyze the scaling limits of Double Gate (DG) underlap andTriple Gate (TG) overlap FinFET structure using 2D and 3D computer simulations respectively. Toanalyze the scaling limits of FinFET structure, simulations are performed using three variables: finthickness,fin-height and gate-length. From 2D simulation of DG FinFET, it is found that the gate-length(L) and fin-thickness (Tfin) ratio plays a key role while deciding the performance of the device. DrainInduced Barrier Lowering (DIBL) and Subthreshold Swing (SS) increase abruptly when (L/Tfin) ratio goesbelow 1.5. So, there will be a trade-off in between SCEs and on- current of the device since on-off currentratio is found to be high at small dimensions. From 3D simulation study on TG FinFET, It is found thatboth fin-thickness (Tfin) and fin-height (Hfin) can control the SCEs. However, Tfin is found to be moredominant parameter than Hfin while deciding the SCEs. DIBL and SS increase as (Leff/Tfin) ratiodecreases. The (Leff/Tfin) ratio can be reduced below 1.5 unlike DG FinFET for the same SCEs. However,as this ratio approaches to 1, the SCEs can go beyond acceptable limits for TG FinFET structure. Therelative ratio of Hfin and Tfin should be maximum at a given Tfin and Leff to get maximum on-current perunit width. However, increasing Hfin degrades the fin stability and degrades SCEs.

Process Benchmarking Through Lean Six Sigma for ERP Sustainability in Small & Medium Enterprises
Rashmi Jha,A. K. Saini
BVICAM's International Journal of Information Technology , 2011,
Abstract: Enterprise Resource Planning was a term restricted purely to elite class. ERP for small business calls for voluminous investments. But the question that kept ringing in the market was can everyone afford it? The answer was a stubborn no initially but not anymore. The world is changing, and new opportunities are appearing every day. Globalization, once the domain for only large companies, is now presenting new markets for growth for small to mid market companies. In today's competitive manufacturing environment, it takes more than quick fixes, outsourcing and downsizing to consistently achieve growth and profit objectives. While these options may yield temporary financial relief, they will not lead the way to long-term growth and profitability. For companies to grow and consistently exceed bottom line expectations, they need to get lean. And to get lean they should master eight basics of Lean Six Sigma. Today every organization strives to optimize its operations, further based on the type of problems, combining Lean and/or Six Sigma tools with traditional project management techniques for ERP Implementation can be a powerful combination for ERP Sustainability in Small & Medium Enterprises.
