Universal models for Lorenz maps

The existence of smooth families of Lorenz maps exhibiting all possible dynamical behavior is established and the structure of the parameter space of these families is described

Influence of Delta Morphodynamics on Coastal Response to Climate Change

This study examined the proposition that deltas are important sedimentary structures in the control of depositional processes responsible for morphologic evolution of coastlines. More specifically, deltaic sensitivity to external forcing factors including climate change and sea-level variations, that influence morphologic evolution of adjacent coastlines while regulating sediment dispersal patterns. This influence depends on the morphologic complexity of the coastline and the relation between the existing sedimentary structures. The study combined field data and modelling techniques to examine the dependence of adjacent coastal behaviour on a deltaic structure assessing the contribution of each forcing factor on sediment mass balance and morphologic evolution. This dependence was explored using as a natural laboratory, the Caparica coastal cell located on the Portuguese west coast, south of Lisbon, which was studied using two different approaches: coastal evolution since sea-level stabilization (<7ky BP) and risk based forecast modelling for coastline position. Results demonstrate that coastline position and sedimentary structures are mainly dependent on sediment supply conditions governed by deltaic behaviour along the proximal adjacent-coast. The influence of deltaic processes is characterized by highly dynamic sediment exchanges that subordinate effects of climate change and sea-level variations on coastal evolution for frequently observed conditions and conservative predictions using average values of climatic variations. These factors only become relevant when extreme conditions are considered. In contrast, the morphology of the distal adjacent-coast is not governed by sediment exchanges with the delta being influenced by wave refraction over bathymetry. This coastal segment is more responsive than the proximal coast to sea level rise in model forecasts

The multipliers of periodic points in one-dimensional dynamics

It will be shown that the smooth conjugacy class of an $S-$unimodal map which does not have a periodic attractor neither a Cantor attractor is determined by the multipliers of the periodic orbits. This generalizes a result by M.Shub and D.Sullivan for smooth expanding maps of the circle

Infection start primarily by inhalation of environmental basidiospores or poorly encapsulated yeast cells (with less than 5 μm), that can disseminate, after a latent period within lung lymph nodes. There are two principal species of Cryptococcus spp related with this disease: Cryptococcus neoformans and Cryptococcus gattii. Cryptococcus albidus and Crytpococcus laurentii are rarely associated with cryptococcosis in humans.info:eu-repo/semantics/publishedVersio

Business-to-Business Solutions for a Changing Scenario in Brazilian Economy

This paper has the purpose of describing the development of Business-to-Business in Brazil and its adoption by companies and the government to reduce costs and reach new markets. It also shows the support provided by the Brazilian Government to this development, by means of the creation of the Electronic Commerce Executive Committee, in a joint effort with the private sector, and the implantation of a financing instrument for small and medium companies destined to electronic commerce, among other measures. Examples of creative solutions adapted to the conditions of the Brazilian economy, such as the Energy Marketplaces, established during the electric-energy rationing in Brazil, between May 2001 and February 2002, where thousands of companies were able to commercialize their energy quotas by means of electronic auctions, as well as tools directed to the governmental acquisition of goods and services, show the great potential of Business-toBusines
