A Belle Époque caipira: problematizações e oportunidades interpretativas da modernidade e urbanização no Mundo do Café (1852-1930) - a proposta do Cemumc

Este artigo visa apontar a importância historiográfica de interpretar e compreender de maneira ampla e exaustiva as imagens, os discursos e demais vestígios que nos permitam ter acesso às sociabilidades, representações, projetos e práticas vivenciadas pelos habitantes das cidades do Brasil caipira, que apresentaram transformações geradas pela modernidade, no limiar do XX, em decorrência da nova dinâmica capitalista gerada pelos efeitos da expansão da economia cafeeira nessa região.

New record of Rhagomys rufescens (Thomas 1886) (Rodentia : Muridae : Sigmodontinae) in the Atlantic forest of southeastern Brazil

Rhagomys rufescens is a threatened Sigmodontinae rodent from the Atlantic forest of southeastern Brazil, known by a few specimens deposited in scientific collections. This work presents a new record of this species, collected in Parque Estadual da Serra do Mar-Nucleo Picinguaba (Ubatuba, SP) in April 2002, and some biological data. This finding reinforces the urgency of improving collecting efforts in Atlantic forest, in order to know and preserve its biodiversity.

3-BODY COLLAPSE FOR TABAKIN POTENTIALS AND THE THOMAS EFFECT

A system constituted of three bosons interacting via two-body separable potentials with fixed two-boson binding is known to lead to bound-state collapse in the case where the potential parameters allow two-boson S-matrix poles close to (resonance) and on (continuum bound state) the real momentum axis. The collapse is shown to be accompanied by an increase in the average kinetic energy of the two-body bound state, which signals a decrease in the range of the two-body interaction for fixed two-body binding. The collapse is claimed to be a manifestation of the well-known Thomas effect which leads to a collapse of the three-body system when the range of the two-body interaction goes to zero for a fixed two-body binding.
