1. SOIL PHYSICAL ATTRIBUTES AND PRODUCTION COMPONENTS OF SUGARCANE CULTIVARS IN CONSERVATIONIST TILLAGE SYSTEMS
ABSTRACT Machine traffic and conventional tillage can cause structural degradation of the soil, affecting the physical attributes and, consequently, the production and longevity of the sugarcane field. The objective of this study was to evaluate the production components of sugarcane cultivars (RB965902, RB985476, RB966928, RB855156, RB975201, RB975242, RB03

2. RESILIENCE AND ENTERPRISE ARCHITECTURE IN SMES
ABSTRACT Considering that SMEs need to embrace the drivers of resilience and that a well-defined and readily available Enterprise Architecture (EA) supports enterprise integration by enabling the common view of business processes, data and systems across the enterprise and its partners, we can say that EA is one of the tracks making resilience predictable an

3. Planejamento periódico de trajetórias de sistemas afins sem arrasto em grupos de Lie compactos / Periodic motion planning of trajectories for control-affine driftless systems in compact Lie groups
We treat the periodic motion planning problem: given a periodic trajectory of a control-affine driftless system in a compact and connected Lie group G and an initial condition in G, find another trajectory of the same system satisfying the initial condition given and that asymptotically tracks the periodic trajectory. We solve this problem locally (for initi

4. Mechanized methods for harvesting residual biomass from Mediterranean fruit tree cultivations
This study evaluates the technology and work systems used in order to harvest residual biomass from pruning in the specific conditions of Mediterranean fruit orchards (narrow distances between crop-rows). Harvesting has been divided into several types of operations - pruning, biomass alignment between crop tracks, biomass concentration in piles, chipping and

5. Estratigrafia de sequências do intervalo aptiano ao albino na Bacia do Araripe, NE do Brasil / Estratigrafia de sequências do intervalo aptiano ao albino na Bacia do Araripe, NE do Brasil
This study has as a main objective to make a detailed stratigraphic analysis of the Aptian-Albian interval in the east part of Araripe Basin, NE of Brazil which correspond, litostratigraphically, to Rio Da Batateira, Crato, Ipubi and Romualdo formations. The stratigraphic analysis was based on three different stages, the 1D, 2D and 3D analysis; these ones we

6. Produção flexivel e degradação da força de trabalho no Brasil
The present work analyzes as the movements of precarization of the work relations and of absorbing use of the work force of implemented from the productive reorganization and of the adoption of the agenda of restrictive economics politics also they are disclosed through the precarization of the general quality of the Brazilian force of work. In principle and

7. TransformaÃÃes espaÃo-temporais da Mata de Dois IrmÃos a partir da avaliaÃÃo dos processos de apropriaÃÃo do espaÃo
The woods of Dois IrmÃos are located in the mucipality of Recife, State of Pernambuco, and constitute one of the few remainders of the Atlantic rainforest within the State. This ecosystem was made a State Park in 1998, encompassing and area of 387.4 hectares, including within its perimeter the forest reservation, the water reservoires of Prata, do Meio and

8. Efeito da fragmentação florestal sobre as comunidades de morcegos do Município de Blumenau, SC
The primary forests of the region of the Vale do Itajaí had been object of intense exploration for some decades, leaving as resulted the reduction of the forest covering and the fragmentation of the same one in remainders that today are presented in different sucessions stadiums. The fragmentation of habitat brings consequences on biodiversity, becoming the

10. Hyper Friburgo: um sistema hyper texto baseado em agentes inteligentes para informações turísticas / Hyper Friburgo: a hyper text system based on intelligent agents for touristic informations
Nova Friburgo is a Brazilian tourist city, which attracts different types of visitors. This dissertation describes an intelligent system to be installed at a tourist information center for assisting those who need directions to this citys major attractions. Currently, there is an ordinary multimedia application for tourism support but such system is being ex

11. Tracking neuronal fiber pathways in the living human brain
Functional imaging with positron emission tomography and functional MRI has revolutionized studies of the human brain. Understanding the organization of brain systems, especially those used for cognition, remains limited, however, because no methods currently exist for noninvasive tracking of neuronal connections between functional regions [Crick, F. & Jones

12. Robust perfect adaptation in bacterial chemotaxis through integral feedback control
Integral feedback control is a basic engineering strategy for ensuring that the output of a system robustly tracks its desired value independent of noise or variations in system parameters. In biological systems, it is common for the response to an extracellular stimulus to return to its prestimulus value even in the continued presence of the signal—a
