Simple-methods of estimation of standard plate count, count of enterobacteriaceae (coliform count) and count of yeasts and molds

Comparison of Limulus assay, standard plate count, and total coliform count for microbiological assessment of renovated wastewater.

The Limulus endotoxin assay was compared to the standard plate count and total coliform count for assessment of the bacteriological quality of reclaimed wastewater. A total of 48 water samples from an advanced waste treatment plant in Dallas, Tex. were examined by the three techniques. Limulus assays were technically simpler to perform and provided results much sooner than conventional culture ...

Interactions between heterotrophic plate count bacteria and coliform organisms.

Studies were initiated to investigate the interactions between heterotrophic plate count bacteria and coliform organisms. We used spiked samples to show that heterotrophic plate count bacteria could reduce coliform densities by more than 3 logs within 8 days. Some heterotrophic plate count bacteria were able to cause injury to the coliform population. A significant correlation (r = 0.66; P less...

Explanations Count Explanations Count

In research areas such as decision support systems, one of the crucial features is the ability to automatically explain decisions. However, this ability does not typically play a large role in computer games. Here, I suggest that this situation will change: research on the automatic generation of explanations will have real import for many types of computer games. I discuss four possible ways t...

Estimation of Count Data using Bivariate Negative Binomial Regression Models

Abstract Negative binomial regression model (NBR) is a popular approach for modeling overdispersed count data with covariates. Several parameterizations have been performed for NBR, and the two well-known models, negative binomial-1 regression model (NBR-1) and negative binomial-2 regression model (NBR-2), have been applied. Another parameterization of NBR is negative binomial-P regression mode...
