Empirical Analysis of StratSoy Use: Changes in Uses and Users Over Time Using Statistics From the Web Site
… logistic diffusion pattern consistent with an S-shaped curve was observed for most top-level domains' use of the StratSoy site. Academic users are the early adopters for most uses of the site. In addition to documenting the adoption of a web site, the dissertation demonstrated the use of a new …

Evaluation of economical sorbents for the removal of metolachlor from contaminated wastewater
… levels tested. However, isotherm plots showed S-shaped curve behavior for all of the sorbents in the presence of unformulated metolachlor, while a C-shaped curve was seen when the sorbents were mixed with formulated metolachlor. This suggests that different bonding mechanisms may be involved for …

Money does not buy happiness… or does it? An investigation of the relationship between individual income and life satisfaction in the national income dynamics study
… the discovery of non-linear relations (e.g. an S-shaped curve). The purpose of this dissertation was to explore the nature of the relationship between income and life satisfaction in the National Income Dynamics Study (NIDS), a South African household panel study which gathers various wellbeing …

Some physical and chemical aspects of ammoniacal nitrogen in soils
… slopes obtained for different sections of the curves were related to reactions involving "hydrogen", exchange sites and physical adsorption. The S-shaped curve obtained for high concentrations suggests the formation of polymolecular layers. Ammonia adsorption by neutral and basic soils also …

Uniform heating of thin ceramic slabs in a multimode microwave cavity
Two-dimensional reaction diffusion equations, which contain a functional and an inhomogeneous source term, are good models for describing microwave heating of thin ceramic slabs and cylinders in a multi mode, highly resonant cavity. A thin ceramic slab situated in a TEN03 rectangular cavity modeled …

Identification of Novel Allosteric Regulators of Human Erythrocyte Pyruvate Kinase
… steady state kinetics of R-PK gave a typical S-shaped curve that fitted a signloidal function indicative of allosterism. All the kinetic parameters of our enzyme were in excellent agreement with native R-PK activity as previously reported5, 57. R-PK activity in the presence of the analyzed …
