A Economicidade no sistema de Compras Centralizadas no Exército Brasileiro
O sistema de compras públicas centralizadas vem, com o passar dos anos, ganhando importância em virtude da possibilidade de proporcionar, de forma eficaz, melhor emprego dos recursos públicos, sendo o Exército, componente do sistema de Administração Pública, um ator importante na realização desta Política Pública.

Peritrophic Membranes
Peritrophic membranes are secretion products of the midgut. For long they have been related only to insects, but they occur widely in the animal kingdom. They effect a part of the gut lumen and function not only as a mechanical protection barrier, but also as an ultrafilter, a barrier to parasites, and as envelopes for fecal pellets. Such peritrophic envelopes are of great ecological importance in marine environments. The book is divided into the following themes: - Occurrence - Formation and Structure - Degradation - Chemical Composition - Functions. It is the first comprehensive compilation of all data concerning peritrophic membranes and will provide a basis for future researches in this up to now often neglected field.
Biology of the Insect Midgut
Entomological research benefits from a great diversity of technical approaches - from the molecular to the descriptive - and these are applied to an even greater diversity of insect species. As a consequence, common themes and trends in entomological research can often be overlooked as each researcher focuses on his or her own area of interest. The purpose of this volume is to bring together diverse areas of research under one common theme. The book is divisible into four conceptual areas: the structural biology of the midgut; digestion and transport; the insect midgut as a target for control strategies; and the idgut as an environment for other organisms. Each chapter is written by scientists active in the reviewed research area and a truly international team of contributors has been chosen by the editors. Biology of the Insect Midgut will be of immense use to advanced undergraduate and postgraduate students, and researchers in entomology, physiology and pest control.

Dietrich Bartel then turns to more detailed considerations of the musical-rhetorical figures that were developed in Baroque treatises and publications. After brief biographical sketches of the major theorists, Bartel examines those theorists’ interpretation and cl...
