1. Modelagem tridimensional da estrutura trófica em ecossistemas aquáticos continentais rasos
Esta tese identificou vários aspectos importantes da estrutura trófica e dinâmica de nutrientes em ecossistemas aquáticos sujeitos a perturbações externas, tais como mudanças no nível da água, aumento de carga de nutrientes e matéria orgânica, biomanipulação e clima. Para descrever tais efeitos sobre a estrutura trófica, um complexo modelo ecol

2. The “excess entropy” around nonequilibrium steady states, (δ2S)ss, is not a Liapunov function
In a response to my recent paper [Fox, R. F. (1979) Proc. Natl. Acad. Sci. USA 76, 2114-2117], Nicolis and Prigogine [Nicolis, G. & Prigogine, I. (1979) Proc. Natl. Acad. Sci. USA 76, 6060-6061] reasserted that the “excess entropy” around nonequilibrium steady states, (δ2S)ss, is a Liapunov function. A simple, explicit counterexample which invalidates t

3. Strain-dependent cross-bridge cycle for muscle. II. Steady-state behavior.
Quantitative predictions of steady-state muscle properties from the strain-dependent cross-bridge for muscle are presented. With a stiffness of 5.4 x 10(-4) N/m per head, a throw distance of 11 nm, and three allowed actin sites/head, isometric properties and their dependence on phosphate and nucleotide levels are well described if the tension-generating step

4. 8-vinyl-deoxyadenosine, an alternative fluorescent nucleoside analog to 2′-deoxyribosyl-2-aminopurine with improved properties
We report here the synthesis and the spectroscopic characterization of 8-vinyl-deoxyadenosine (8vdA), a new fluorescent analog of deoxyadenosine. 8vdA was found to absorb and emit in the same wavelength range as 2′-deoxyribosyl-2-aminopurine (2AP), the most frequently used fluorescent nucleoside analog. Though the quantum yield of 8vdA is similar to that o
