An M x n matrix C is called Mange matrix if c,, + cTT < clr + cr, for all 1 < i -c r < rn, 1 < j < s d n. In this paper we present a survey on Monge matrices and related Monge properties and their role in combinatorial optimization. Specifically, we deal with the following three main topics: (i) fundamental combinatorial properties of Monge structures, (ii) applications of Monge properties to o...

Resumo Este artigo discute a gênese da psicotécnica nas décadas de 1920 1940, analisando, forma comparada, três cursos ministrados em São Paulo: por Roberto Mange, no Liceu Artes e Ofícios, 1926, na Escola Livre Sociologia Política Paulo, 1934; Henri Piéron, Normal 1926. A análise aqui envidada questiona associação causal entre taylorismo, que coloca o nome Mange ao mesmo tempo como precursor i...

The raccoon dog (Nyctereutes procyonoides) is an introduced species in Europe with a continually expanding range. Since the species is capable of affecting local ecosystems and is a vector for a number of severe zoonotic diseases, it is important to understand its food habits. Raccoon dog diet was studied in Estonia by examining the contents of 223 stomach samples collected during the coldest p...
