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 Listeria spp. from drains to food contact surfaces does occur and increases with increased proximity to the drain.

＜正＞ Unit selection-based speech synthesis has recently been the focus of much attention in the speech synthesis community. In general, the speech quality from such a system achieves a high degree of naturalness and good intelligibility. However, examining and selecting units for synthesis as a runtime operation makes the unit selection process computationally expensive. considerable attention has been focused on reducing the complexity of unit selection while maintaining quality. Previous approaches to speeding up the process of runtime unit selection have focused on two aspects. （1） By limiting the number of candidate synthesis units considered in the unit selection process, the number of calculations required can be reduced. （2） By precomputing part of the needed calculations, the runtime complexity can be reduced. Much progress has been made using these methods, but usually at the expense of quality. We present two methods of reducing the complexity of the calculation that avoid any reduction in synthesis quality, while allowing a very fast unit selection process. Results are presented for the reduction in complexity of the calculation process, and for a perceptual experiment that shows quality is not reduced relative to a full unit selection process.

Researchers in the past had noticed that application of Artificial Neural Networks （ann） in place of conventional statistics on the basis of data mining techniques predicts more accurate results in hydraulic predictions. Mostly these works pertained to applications of ann. Recently, another tool of soft computing, namely, Genetic Programming （GP） has caught the attention of researchers in civil engineering computing. This article examines the usefulness of the GP based approach to predict the relative scour depth downstream of a common type of ski-jump bucket spillway. Actual field measurements were used to develop the GP model. The GP based estimations were found to be equally and more accurate than the ann based ones, especially, when the underlying cause-effect relationship became more uncertain to model.

The increasing pace of urbanization means that cities and global organizations are looking for ways to increase energy efficiency and reduce emissions. combined cooling, heating, and power （ccHP） systems have the potential to improve the energy generation efficiency of a city or urban region by providing energy for heating, cooling, and electricity simultaneously. The purpose of this study is to estimate the water consumption for energy generation use, carbon dioxide （cO2） and NOx emissions, and economic impact of implementing ccHP systems for five generic building types within the Atlanta metropolitan region, under various operational scenarios following the building thermal （heating and cooling） demands. Operating the ccHP system to follow the hourly thermal demand reduces cO2 emissions for most building types both with and without net metering. The system can be economically beneficial for all building types depending on the price of natural gas, the implementation of net metering, and the cost structure assumed for the ccHP system. The greatest reduction in water consumption for energy production and NOx emissions occurs when there is net metering and when the system is operated to meet the maximum yearly thermal demand, although this scenario also results in an increase in greenhouse gas emissions and, in some cases, cost. ccHP systems are more economical for medium office, large office, and multifamilv residential buildings.
