1.1. Graphs. Graphs, or abstract collections of nodes and edges, form the main objects studied in the theory of complex networks. These models can be classified according to many different types of topological properties, but the underlying structures are quite simple. The general procedure for modeling with networks is to first identify the objects of interest (nodes), the crucial relations be...

Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI) is a measure of feed efficiency, and is defined as the difference between an animal's actual feed intake and its expected feed intake based on its size and growth. It is independent of the level of production, and the lo...

The mechanisms for intraseasonal variability of the southern hemisphere (SH) winter are studied using a nonlinear non-divergent barotropic potential vorticity model on the sphere. The possibility of low frequency unstable modes induced by topography is examined to compare with the northern hemisphere (NH) case. According to this simple model for the SH winter the most important mechanism in cre...

Exercise 1.2. If A,B ⊂ R,m∗(A) = 0, then m∗(A ∪B) = m∗(B) Proof: m∗(A ∪B) ≤ m∗(A) +m∗(B), and m∗(B) ≤ m∗(A ∪B), hence we have m∗(B) ≤ m∗(A ∪B) ≤ m∗(A) +m∗(B) = m∗(B) ∴ m∗(A ∪B) = m∗(B) Exercise 1.3. Prove E ∈M iff ∀ > 0,∃O ⊂ R open, such that E ⊂ O and m∗(O\E) < Proof: (⇒) O\E = E ∩O implies that m∗(O\E) = m∗(Ec ∩O), but we have m∗(O) = m∗(Ec ∩O) +m∗(E ∩O) So suppose m∗(E) < ∞ ⇒ m∗(Ec ∩ O) = m∗...

Human eating habits in the Amazon, especially in riparian communities, include a series of dietary restrictions (taboos) resulting, in part, from the cultural miscegenation (Native Brazilians, Africans, and Portuguese settlers) that occurred during the formation of this population.1 Among these food taboos, the most important refers to foods considered “remosos” (harmful), an adjective attribut...
