Assessing contaminated sediments in the context of multiple stressors
(John Wiley & Sons, Inc., 2010-12)
Sediments have a major role in ecosystem functioning but can also act as physical or chemical stressors. Anthropogenic activities may change the chemical constituency of sediments and the rate, frequency, and extent of ...
Numerical parameter identifiability and estimability: Integrating identifiability, estimability, and optimal sampling design
(Elsevier, 1985-12)
We define two levels of parameters. The basic parameters are associated with the model and experiment(s). However, the observations define a set of identifiable observational parameters that are functions of the basic ...
Development of pure culture biofilms of P. putida on solid supports
(Wiley Subscription Services, Inc., A Wiley Company, 1991-03-15)
Pseudomonas putida biofilms were developed on and biofilm accumulation rate data were obtained for the following two classes of support materials: charged surfaces and noncharged hydrophobic and hydrophilic surfaces. The ...
Kinetics of the conversion of glucose to gluconic acid by Pseudomonas ovalis
(Wiley Subscription Services, Inc., A Wiley Company, 1970-03)
The concept of a “critical oxygen concentration” is conventionally considered to hold for the submerged aerobic fermentation of glucose to gluconic acid. Above the critical level the fermentation rate is supposedly independent ...
Modeling and analyzing HIV transmission: the effect of contact patterns
(Elsevier, 1988-12)
A compartmental model is presented for the spread of HIV in a homosexual population divided into subgroups by degree of sexual activity. The model includes constant recruitment rates for the susceptibles in the subgroups. ...
Growth equations: A general equation and a survey of special cases
(Elsevier, 1980-04)
Although growth in its various manifestations has been studied for centuries and although there are a large number of well-established growth "laws," that work is almost entirely empirical and lacks a theoretical foundation ...
Assessing microbial competition in a hydrogen‐based membrane biofilm reactor (MBfR) using multidimensional modeling
(Cambridge University PressWiley Periodicals, Inc., 2015-09)
The membrane biofilm reactor (MBfR) is a novel technology that safely delivers hydrogen to the base of a denitrifying biofilm via gas‐supplying membranes. While hydrogen is an effective electron donor for denitrifying ...
Prediction of protein function by discriminant analysis
(Elsevier, 1986-10)
Approximately 53% the protein sequences in the National Biomedical Research Foundation (NBRF) database can be allocated to one of 26 functional classes, each of which can be characterized by the joint occurrence of four ...
Increase in mercury in Pacific yellowfin tuna
(University of California PressWiley Periodicals, Inc., 2015-04)
Mercury is a toxic trace metal that can accumulate to levels that threaten human and environmental health. Models and empirical data suggest that humans are responsible for a great deal of the mercury actively cycling in ...
