The physical capacity of different professional groups of Brazilian Amazonians, studied by cycle ergometry () [PDF]
A study of the physical performance of seven different professional groups living in the Brazilian Amazon was performed. The level of the physical capacity was measured using the ergometric bicycle.

Finite Vertex Bi-Primitive 2-Arc Transitive Graphs Admitting a Two-Dimensional Linear Group
A graph is said to be vertex bi-primitive, if it is a bipartite graph, and the setwise stabilizer of its automorphism group acts primitively on two bi-parts.

Imprimitive permutations in primitive groups
The goal of this paper is to study primitive groups that are contained in the union of maximal (in the symmetric group) imprimitive groups. The study of types of permutations that appear inside primitive groups goes back to the origins of the theory of permutation groups. However, this is another instance of a situation common in mathematics in which a

Collineation groups of translation planes of small dimension
A subgroup of the linear translation complement of a translation plane is geometrically irreducible if it has no invariant lines or subplanes. A similar definition can be given for geometrically primitive.

Context of culture: Critique of the primitive mind [PDF]
The author of this paper has the intention to reach the new meaning and sense of the primitive mentality by analyzing it in early social communities. He also wants to point out the possible reflections of the spirit and consciousness of our ancestors ...

Testing Matrix Groups for Primitivity
The authors describe an algorithm which seeks to decide whether or not a given irreducible matrix group of finite dimension defined over a finite field preserves a nontrivial system of blocks of imprimitivity in its action on the underlying vector space.

Reconstructing enzyme evolution by protein engineering
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
