1. Organization of instabilities in multispecies systems, a test of hierarchy theory.

The hierarchy theory predicts that system components functioning at lower levels of hierarchy operate or change at higher rates than the components at the level(s) above. If this prediction is correct, then interpretation of stability in complex ecological systems may be in need of revision. We test the prediction using a model of hierarchical structure of h

2. Hierarquia de dominância durante a obtenção de Alimento em cebus apella e cebus libidinosus em Cativeiro

The analysis of the index of hierarchy and structural models of the formation of groups allowed to establish the hierarchical position of members of two groups of the genus Cebus. By the analyses of the hierarchical positions and the application of tests to obtain a food resource (TORA), we know the difference between these groups and groups in the wild. The

3. Hierarquias de sistemas de dedução natural e de sistemas de tableaux analiticos para os sistemas Cn de da Costa

In this work, we introduce the hierarchy of propositional natural deduction systems DNCn, 1≤n≤ω, and the hierarchy of quantificational natural deduction systems DNCn*, 1≤n≤ω. We prove that each one of the systems of the hierarchies is equivalent to the corresponding system of the hierarchy of da Costa´s propositional paraco

4. Expression of an early gene in the flagellar regulatory hierarchy is sensitive to an interruption in DNA replication.

Genes involved in the biogenesis of the flagellum in Caulobacter crescentus are expressed in a temporal order and are controlled by a trans-acting regulatory hierarchy. Strains with mutations in one of these genes, flaS, cannot transcribe flagellar structural genes and divide abnormally. This gene was cloned, and it was found that its transcription is initia

5. Timing of flagellar gene expression in the Caulobacter cell cycle is determined by a transcriptional cascade of positive regulatory genes.

The Caulobacter crescentus flagellar (fla) genes are organized in a regulatory hierarchy in which genes at each level are required for expression of those at the next lower level. To determine the role of this hierarchy in the timing of fla gene expression, we have examined the organization and cell cycle regulation of genes located in the hook gene cluster.

6. Benjamin—Ono-related equations and their solutions

It is shown that the Benjamin—Ono equation is one of a hierarchy of nonlinear partial differential singular integral equations. Explicit multisoliton solutions are constructed for all equations of the hierarchy.

7. Person hierarchy in Avá Guarani : a study of distributed morphology / Hierarquia de pessoa em Avá Guarani : considerações a partir da morfologia distribuída

This master thesis describes and analyses morphological and syntactic processes related to person hierarchy in the Ava-Guaraní language (Tupi-Guaraní language family / Tupi stock). The work employs a general Generative framework, guided in particular by the principles of Distributed Morphology (HALLE; MARANTZ, 1993; HALLE, 1997; MARANTZ, 1997). Person hier

8. Negative transcriptional regulation in the Caulobacter flagellar hierarchy.

The Caulobacter crescentus flagellum is formed at a specific time in the cell cycle and its assembly requires the ordered expression of a large number of genes. These genes are controlled in a positive trans-acting hierarchy that reflects the order of assembly of the flagellum. Using plasmids carrying transcriptional fusions of either a neo or a lux reporter

9. The hierarchy of human rights international treaties: an analysis of the amendment n 45/2004 / A hierarquia dos tratados internacionais de direitos humanos: uma análise a partir da emenda constitucional 45/2004

The present study analyzes the hierarchy of human rights international treaties ratified by Brazil, considering the change in the Constitution occurred with amendment no. 45 of December 2004. The reform introduced a 3rd to Article 5th, expressly admitting that human rights treaties have VWDWXV of constitutional norms. The justification of the study carried o

11. New solutions to the hierarchy problem

After summarizing the status of the Standard Model, we focus on the Hierarchy Problem and why we believe this strongly suggests the need for new physics at the TeV scale. We then concentrate on theories with extra dimensions and their possible manifestations at this scale.

12. The Hierarchy of Hamiltonians for a Restricted Class of Natanzon Potentials

The restricted class of Natanzon potentials with two free parameters is studied within the context of Supersymmetric Quantum Mechanics. The hierarchy of Hamiltonians and a general form for the superpotential is presented. The first members of the superfamily are explicitly evaluated.
