Biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2001-02-05)
Exopolymer-producing bacteria can be used to modify soil profiles for enhanced oil recovery or bioremediation. Understanding the mechanisms associated with biomass plug development and propagation is needed for successful ...
Records of Growth and Weaning in Fossil Proboscidean Tusks as Tests of Pleistocene Extinction Mechanisms.
(2016)
Mammoths (Mammuthus primigenius) and mastodons (Mammut americanum) became extinct about 10,000 ago. Their disappearances coincide broadly with the timing of two possible causal factors: climate change leading into the ...
Three contraceptive acceptance strategies
(Elsevier, 1979-02)
Three main classes of contraceptive acceptance strategy may be distinguished: "fixed duration T" (women counseled to accept T months after childbirth); "postamenorrheic" (accept directly after the first postpartum menses), ...
Reduction of porous media permeability from in situ Leuconostoc mesenteroides growth and dextran production
(Wiley Subscription Services, Inc., A Wiley Company, 1996-04-05)
In situ growth of bacteria in a porous medium can alter the permeability of that media. This article reveals that the rate of permeability alteration can be controlled by the inoculation strategy, nutrient concentrations, ...
Distribution of nodes of a tree by degree
(Elsevier, 1970)
Two types of random trees, "static" and "growing," are studied. The "growing" type of trees is constructed with an ordering bias imposed on its population of N nodes. Exact formulas for the expected number of nodes of ...
Cell cycle dependence of retroviral transduction: An issue of overlapping time scales
(Wiley Subscription Services, Inc., A Wiley Company, 1998-04-20)
Recombinant retroviruses are currently used as gene delivery vehicles for the purpose of gene therapy. It is generally believed that the efficiency of retroviral transduction depends on the cell cycle status of the target ...
A structured model of photosynthesis in anacystis nidulans
(Wiley Subscription Services, Inc., A Wiley Company, 1978-01)
No Abstract.
Regulated expression of polysaccharide utilization and capsular biosynthesis loci in biofilm and planktonic Bacteroides thetaiotaomicron during growth in chemostats
(Wiley Periodicals, Inc., 2014-01)
Bacteroides thetaiotaomicron is a prominent member of the human distal gut microbiota that specializes in breaking down diet and host‐derived polysaccharides. While polysaccharide utilization has been well studied in B. ...
Mass transfer effects on microbial uptake of naphthalene from complex NAPLs
(Wiley Subscription Services, Inc., A Wiley Company, 1998-12-20)
The bioavailability of naphthalene present as a component of a complex nonaqueous phase liquid (NAPL) comprised by nine aromatic compounds was investigated. Specifically, the effects of naphthalene mass transfer from the ...
Fluid shear stress stimulates breast cancer cells to display invasive and chemoresistant phenotypes while upregulating PLAU in a 3D bioreactor
(Wiley Periodicals, Inc., 2019-11)
Breast cancer cells experience a range of shear stresses in the tumor microenvironment (TME). However most current in vitro three‐dimensional (3D) models fail to systematically probe the effects of this biophysical stimuli ...
