    Notes: An electrochemical treatment system consisting of a pulsed electrical power supply and an electrical treatment chamber was designed and evaluated for inactivation Listeria monocytogenes in recirculated brine for chilling processed bacons. The brine was tested under different currents and temperatures. An average D-value of 1.61 min in the storage tank could be achieved at 7 mA/cm3 current with the fresh brine (t = 0 h). For the spent brine (t = 20 h), the D-value was 2.5 min in the treatment chamber at 35 mA/cm3. The average D-values in the treatment chamber were approximately 2.5 min at all three temperatures (4, 0, -8 8C) at 35 mA/cm3.

    Efficacy of Cetylpyridinium Chlorine on Salmonella Typhimurium and Escherichia coli O157:H7 in Immersion Spray Treatment of Fresh-Cut Lettuce (2003)

    Notes: Fresh-cut lettuce inoculated with Salmonella enterica serovar Typhimurium and Escherichia coli O157:H7 was treated using cetylpyridinium chlorine (CPC) solution in a laboratory-scale immersion spray system. With 0.7 kg/cm2 spray pressure and 1.5-min spray time (ST), both bacteria were significantly reduced (P 〈 0.05) in 0.1% to 0.3% CPC spray treatments, compared with water spray controls. At the same ST, increasing spray pressure from 0.7 to 2.1 kg/cm2 further reduced bacteria by 0.5 to 1.5 log colony-forming units (CFU)/g. The 0.2% and 0.3% CPC treatments resulted in the greatest reduction of S. serovar Typhimurium and E. coli O157:H7, respectively. Similar bacterial reduction could be achieved using shorter ST with extended post-spray exposure time. No color change on the lettuce was observed after CPC treatment.

    The Effect of pH on Inactivation of Pathogenic Bacteria on Fresh-cut Lettuce by Dipping Treatment with Electrolyzed Water (2003)

    Notes: Fresh-cut lettuce samples inoculated with S. Typhimurium, E. coli O157:H7 or L. monocytogenes were dipped into 300 ppm electrolyzed water (EW) at pH 4 to 9 and 30 °C for 5 min. The effects of treatment pH on bacterial reduction and visual quality of the lettuce were determined. The treatments at pH 4 and 8 resulted in the most effective inactivation of E. coli O157:H7, but the effect of pH was not significant (P 〉 0.05) for S. Typhimurium and L. monocytogenes. The treatment at pH 7 retained the best visual quality of lettuce, and achieved a reduction of approximately 2 log CFU/g for above 3 bacteria.

    Texture of Glassy Corn Cakes as a Function of Moisture Content (1998)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Glass transition temperatures of yellow and white corn cakes were investigated within the moisture range of 2 to 32% (w/w) using dynamic differential scanning calorimetry. All measurements were conducted at 10°C/min heating rate, 30 sec equilibrium period, and 1°C amplitude. Effects of water plasticization on corn cakes were predicted by the Gordon-Taylor's equation. Moisture sorption isotherms were established using BET and GAB equations. Relationships were found among glass transition temperature, moisture content and cake texture. The loss of crispness of corn cakes occurred within the glassy state. The initial loss of crispness occurred around monolayer moisture content, and the complete loss of crispness occurred at about 9% moisture with the highest hardness.

    Differential Regulation of APP Secretion by Apolipoprotein E3 and E4 (1996)

    Notes: The apolipoprotein E isozyme, apolipoprotein E4, has been implicated as a risk factor for Alzheimer's disease. One reason for the increased risk may be that apolipoprotein E binds to the Aβ peptide, but there may be other factors as well. We show that apolipoprotein E is a potent regulator of the secretion of amyloid precursor protein. In cultures of PC12 cells, nanomolar levels of apolipoprotein E3 induce a rapid decrease in the secretion of APP, being observable in 30 min. and stable over 24 hours. Apolipoprotein E4, in contrast, increases secretion of APP over a similar time course. Reciprocal changes occur in cellular amyloid precursor protein. Differential characteristics are also seen in apo E binding to the cells, where apo E4 binds over a slower time course than apo E3. These results suggest a novel mechanism by which apolipoprotein E may be influencing the metabolism of amyloid precursor protein.

    Notes: : Predictive models for the survival/death of Campylobacter jejuni and Salmonella Typhimurium during poultry scalding and chilling, as functions of temperature (50 to 60 °C), chlorine level (0 to 50 ppm) and water age (0, 10 h for scalding; 0, 8 h for chilling), were evaluated and developed using the data from previous study. As primary models, the Weibull distribution, exponential, logistic, and Gompertz models were compared. The secondary models were developed by modifying the Davey and polynomial models. Mean Square Errors (MSE) and the plots of predicted in contrast to observed survivors showed a good fit and prediction. The Weibull distribution-based secondary model was selected due to its fewer parameters and better prediction (MSEs 〈 0.4) compared to the other models.

    Antibacterial Efficacy of Electrochemically Activated Solution for Poultry Spraying and Chilling (1999)

    Notes: An electrochemically activated solution (EAS) was evaluated for its antibacterial efficacy against Salmonella typhimurium on chicken carcasses during inside/outside (I/O) birdwasher spraying at 20°C and 413 kPa for 17s and chilling at 4°C for 45 min in a pilot plant. The EAS with 50 ppm of oxidants in terms of free chlorine (CI) in the I/O spray reduced Salmonella on carcasses by 1.39 log10 CFU/carcass, whereas tap water and a 50 ppm (CI) hypochlorite solution reduced Salmonella by 0.86 and 0.87 log10 CFU/carcass, respectively. Further chilling using iced EAS (50 ppm of CI) did not reduce Salmonella on carcasses but eliminated Salmonella in the chiller water.

    Improved Gravimetric Terrain Corrections (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 119 (1994), S. 0 
    Details
    ISSN: 1365-246X
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: The objective of this paper is to improve gravimetric terrain corrections by: (1) investigating the effect of different topographic representations that are suitable for efficient processing of high volumes of data (e.g. the mass prism and the mass line models) on terrain corrections and on geiod computations; (2) accelerating the convergence of fast Fourier transform (FFT)-based terrain-correction formulae; and (3) developing a set of new formulae corresponding to the mass prism topographic model, which can be evaluated efficiently with the 2-D FFT.Terrain corrections were computed on a grid of 600 by 600 points with spacing 30″ by 60″ in the Rocky Mountains of British Columbia, Canada. the effect of using the mass line model instead of the mass prism model is 7.4 mGal (maximum) and 0.7mGal (rms) on the terrain corrections, and 24cm (maximum) and 16cm (rms) on the geoid undulations. the optimizations made on the FFT-based terrain-correction formulae effectively speed up the convergence. the newly developed mass prism terrain-correction formula significantly reduced the required computer time and provided identical results with those from the rigorous numerical integration. On an IBM/RISC machine running AIX, the computation of the 15 convolutions (the matrix size was expanded to 1200 by 1200 after 100 per cent zero-padding) via the new formulae only took 15 min (user time), while the numerical summation method required 83.5 days.
