Produção de matéria seca e sementes de quatro cultivares de feijoeiro conduzido em dois solos sob seis condições hídricas em casa de vegetação.

O trabalho teve como objetivo avaliar a produção de cultivares de feijoeiro sob diferentes condições de umidade, em solos de textura arenosa e argilosa. O experimento foi implantado em casa de vegetação no Campus de Janaúba/UNIMONTES num esquema fatorial composto por dois solos (arenoso e argiloso), seis condições de disponibilidade de água e quatro genótipos de feijoeiro (Talismã, Pérola, Magnífico e Princesa), em um delineamento em blocos casualizados com 3 repetições

The French translation of Albrecht Dürer’s Four Books on Human Proportion, a "crime de lèse-majesté divine"?

L'articolo considera un testo poco conosciuto di Louis Meigret, letterato francese, nella sua prefazione alla traduzione francese del trattato delle proporzioni di Durer. Mostra quanto il problema dell'immagine riformata sia presente nella Francia delle guerre di religioni

Conditioning and Dilation with Coherent Nearly-Linear Models

In previous work [1] we introduced Nearly-Linear (NL) models, a class of neighbourhood models obtaining upper/lower probabilities by means of a linear affine transformation (with barriers) of a given probability. NL models are partitioned into more subfamilies, some of which are coherent. One, that of the Vertical Barrier Models (VBM), includes known models, such as the Pari-Mutuel, the \u3b5-contamination or the Total Variation model as special instances. In this paper we study conditioning of coherent NL models, obtaining formulae for their natural extension. We show that VBMs are stable after conditioning, i.e. return a conditional model that is still a VBM, and that this is true also for the special instances mentioned above but not in general for NL models. We then analyse dilation for coherent NL models, a phenomenon that makes our ex-post opinion on an event A, after conditioning it on any event in a partition of hypotheses, vaguer than our ex-ante opinion on A

On the lower and upper solution method for the prescribed mean curvature equation in Minkowski space

We develop a lower and upper solution method for the Dirichlet problem associated with the prescribed mean curvature equation in Minkowski space {-div( 07u/ 1a1-| 07u|2=f(x,u) in \u3a9 u=0 on 02\u3a9 Here \u3a9 is a bounded regular domain in \u211dNand the function f satisfies the Carath\ue9odory conditions. The obtained results display various peculiarities due to the special features of the involved differential operator

Positive solutions of the Dirichlet problem for the one-dimensional Minkowski-curvature equation

We discuss existence and multiplicity of positive solutions of the Dirichlet problem for the quasilinear ordinary differential equation \begin{equation*} -\Big( u'/{ \sqrt{1-{u'}^2}}\Big)' = f(t,u). \end{equation*} Depending on the behaviour of $f=f(t,s)$ near $s=0$, we prove the existence of either one, or two, or three, or infinitely many positive solutions. In general, the positivity of $f$ is not required. All results are obtained by reduction to an equivalent non-singular problem to which variational or topological methods apply in a classical fashion
