Anadenanthera peregrina var. falcata (angico-do-cerrado), uma leguminosa arbrea, forma associaes simbiticas com bactrias fixadoras de nitrognio (rizbios) e com fungos micorrzicos arbusculares. Com o objetivo de avaliar a eficincia da inoculao de fungos micorrzicos e rizbios no crescimento inicial de plantas de angico-do-cerrado, crescidas em solo autoclavado e em solo no autoclavado com e sem inoculao, foi desenvolvido um experimento em casa de vegetao, utilizando razes micorrizadas de milho e uma mistura de isolados de rizbios como inoculantes. O crescimento das plantas foi influenciado positivamente pela concomitante inoculao do fungo micorrzico e do rizbio, tendo as plantas desse tratamento apresentado biomassa cerca de 60 % maior do que o controle no dcimo ms. A inoculao de apenas um dos microssimbiontes, entretanto, no provocou diferena na produo de biomassa das plantas. A percentagem de colonizao micorrzica foi significativamente mais alta e o nmero de ndulos maior nas razes das plantas crescidas no solo no autoclavado, ocasionados pela populao de fungos e rizbios nativos. Nesse tratamento, houve pequeno acmulo de matria no xilopdio, provavelmente em virtude do dreno fotossinttico por parte dos microssimbiontes, e a concentrao de P na parte area e xilopdio dessas plantas foi cerca de 1,2 e 8 vezes maior, respectivamente, por causa da colonizao micorrzica. The leguminous tree Anadenanthera peregrina var. falcata (angico-do-cerrado) forms symbiotic associations with nitrogen fixing bacteria (rhizobia) and arbuscular mycorrhizal fungi. The aim of this study was the evaluation of the influence of rhizobial and arbuscular mycorrhizal inoculation on the initial growth of angico-do-cerrado plants, in autoclaved and non-autoclaved soil with and without inoculations. The experiment was carried out in a greenhouse using mycorrhized roots of maize and a mixture of rhizobial isolates as inocula. Plant growth was positively affected by dual inoculation of mycorrhizal fungus and rhizobia: plants of this treatment produced 60 % more biomass than in the control in the 10th month. Inoculation of only one microsymbiont, however, did not promote difference in plant growth. Mycorrhizal formation was significantly more extensive and the number of nodules higher in plants of non-autoclaved soil, caused by native soil borne fungi and rhizobia. In this treatment mass accumulation was lowest in the xylopodium, probably because of the photosynthetic drain caused by microsymbionts, and P concentrations in shoot and xylopodium were about 1.2 and 8 times higher in these plants, respectively, due to the mycorrhizal colonization.

Equilibrium statistics of Hamiltonian systems is correctly described by the microcanonical ensemble. Classically this is the manifold of all points in the N−body phase space with the given total energy. Due to Boltzmann-Planck’s principle, e S = tr(δ(E − H)), its geometrical size is related to the entropy S(E,N,V, · · ·). This definition does not invoke any information theory, no thermodynamic limit, no extensivity, and no homogeneity assumption. Therefore, it describes the equilibrium statistics of extensive as well of non-extensive systems. Due to this fact it is the fundamental definition of any classical equilibrium statistics. It addresses nuclei and astrophysical objects as well. S(E,N,V, · · ·) is multiply differentiable everywhere, even at phase-transitions. All kind of phase transitions can be distinguished sharply and uniquely for even small systems. What is even more important, in contrast to the canonical theory, also the region of phase-space which corresponds to phase-separation is accessible, where the most interesting phenomena occur. No deformed q-entropy is needed for equilibrium. Boltzmann-Planck is the only appropriate statistics independent of whether the system is small or large, whether the system is ruled by short or long range forces.

Geometric foundation of thermo-statistics, phase transitions, second law of thermodynamics, but without thermodynamic limit

Description:

A geometric foundation thermo-statistics is presented with the only axiomatic assumption of Boltzmann’s principle S(E, N, V) = k lnW.

A geometric foundation thermo-statistics is presented with the only axiomatic assumption of Boltzmann’s principle S(E, N, V) = k lnW. This relates the entropy to the geometric area e S(E,N,V)/k of the manifold of constant energy in the (finite-N)-body phase space. From the principle, all thermodynamics and especially all phenomena of phase transitions and critical phenomena can unambiguously be identified for even small systems. The topology of the curvature matrix C(E, N) of S(E, N) determines regions of pure phases, regions of phase separation, and (multi-)critical points and lines. Phase transitions are linked to convex (upwards bending) intruders of S(E, N), where the canonical ensemble defined by the Laplace transform to the intensive variables becomes multi-modal, non-local, (it mixes widely different conserved quantities). Here the one-to-one mapping of the Legendre transform gets lost. Within Boltzmann’s principle, Statistical Mechanics becomes a geometric theory addressing the whole ensemble or the manifold of all points in phase space which are consistent with the few macroscopic conserved control parameters. This interpretation leads to a straight derivation of irreversibility and the Second Law of Thermodynamics out of the time-reversible, microscopic, mechanical dynamics. It is the whole ensemble that spreads irreversibly over the accessible phase space not the single N-body trajectory. This is all possible without invoking the thermodynamic limit, extensivity, or concavity of S(E, N, V). Without the thermodynamic limit or at phase-transitions, the systems are usually not self-averaging, i.e. do not have a single peaked distribution in phase Minimize

Equilibrium statistics of Hamiltonian systems is correctly described by the microcanonical ensemble. Classically this is the manifold of all points in the N−body phase space with the given total energy. Due to Boltzmann’s principle, e S = tr(δ(E −H)), its geometrical size is related to the entropy S(E, N, · · ·). This definition does not invoke any information theory, no thermodynamic limit, no extensivity, and no homogeneity assumption, as are needed in conventional (canonical) thermo-statistics. Therefore, it describes the equilibrium statistics of extensive as well of non-extensive systems. Due to this fact it is the general and fundamental definition of any classical equilibrium statistics. It can address nuclei and astrophysical objects as well. As these are not described by the conventional extensive Boltzmann-Gibbs thermodynamics, this is a mayor achievement of statistical mechanics. Moreover, all kind of phase transitions can be distinguished sharply and uniquely for even small systems. In contrast to the Yang-Lee singularities in Boltzmann-Gibbs canonical thermodynamics phase-separations are well treated. 1 Minimize
