Not in front of the children! The controversies of science and science communication for children and youth (Portuguese original version)

Dialogue in science communication is a necessity - everybody agrees on it - because science Brush and technology issues are involved in so many aspects of the citizens life, and in so many cases can raise suspects, fears, worries or, on the contrary, expectations and hopes.But who are the possible interlocutors for scientists Drying Rack and policy

Sigma Partitioning: Complexity and Random Graphs

A $ extit{sigma partitioning}$ of a graph $G$ is a partition of the vertices into sets $P_1, ldots, P_k$ such that for every two adjacent vertices $u$ and $v$ there is an index Collections $i$ such that $u$ and $v$ have different numbers of neighbors in $P_i$.The $ extit{ sigma number}$ of a graph $G$, denoted by $sigma(G)$, is the minimum number $

Genetic evidence for plastic reproductive philopatry and matrotrophy in blacktip reef sharks (Carcharhinus melanopterus) of the Moorea Island (French Polynesia)

Abstract The exploitation of sharks and the degradation of their habitats elevate the urgency to understand the factors that influence offspring survival and ultimately shark reproductive success.We monitored and sampled blacktip reef sharks (Carcharhinus melanopterus) in nursery habitats of Moorea Island (French Polynesia), to improve knowledge on

Fermion pair radiation from accelerating classical systems

Abstract Accelerating classical systems that couple to a fermion-antifermion pair at the microscopic level can radiate pairs of fermions and lose energy in the process.In this work, we derive the generalization of the Larmor formula for fermion pair radiation.We focus on the case of a point-like classical source in an elliptical orbit that emits fe
