Eficácia de plantas para o controle de nematóides gastrintestinais de pequenos ruminantes: revisão de estudos publicados
RESUMO: As helmintoses gastrintestinais constituem um dos principais fatores limitantes para a ovinocaprinocultura em todo o mundo e a saúde dos rebanhos depende de um efetivo controle antiparasitário. A resistência aos anti-helmínticos representa um dos entraves para esse controle e a busca por novas bases tem sido um desafio constante. A utilização da fitoterapia na medicina veterinária const...

Recently observed social trends point to greater social approximation of individuals through technological platforms, as the increasing success of sites such as Orkut, MySpace, MSN, among others. The mobile social networks are also gaining adepts for having pervasives and customized features. In this demonstration, we show a concept of a mobile social network for students seeking study partners...

The Classification Problem is the problem of deciding whether a simple graph has chromatic index equals to ∆ or ∆+1, where ∆ is the maximum degree of the graph. It is known that to decide if a graph has chromatic index equals to ∆ is NP-complete. A split graph is a graph whose vertex set admits a partition into a stable set and a clique. The chromatic indexes for some subsets of split graphs, s...

Let σk(n) be the sum of the kth powers of the divisors of n. Here, we prove that if (Fn)n≥1 is the Fibonacci sequence, then the only solutions of the equation σk(Fm) = Fn in positive integers k ≥ 2, m and n have k = 2 and m ∈ {1, 2, 3}. The proof uses linear forms in two and three logarithms, lattice basis reduction, and some elementary considerations.

It is known now that chiral symmetry restoration requires the meson-nucleon coupling to be density dependent in nuclear-matter mean-field models. We further show that quite generally, the quark and gluon condensates in medium are related to the trace of energy-momentum tensor of nuclear matter and in these models the incompressibility, K, must be less than thrice the chemical potential, μ. In t...
