DINÂMICA POPULACIONAL DOS PROJETOS DE ASSENTAMENTOS DA REGIONAL DO BAIXO ACRE

O propósito deste trabalho é tecer algumas considerações sobre a dinâmica populacional em quatros projetos de assentamento da microrregião do Baixo Acre e suas implicações no desenvolvimento regional, buscando a compreensão a respeito dos agentes econômicos e sua relação com o êxodo rural, movimento migratório e a influência dos aspectos de infraestrutura exercidos pela capital do Estado do Acre, Rio Branco. No primeiro momento o estudo apresenta o cenário que o desenvolvimento regional transcorre na formação do novo rural brasileiro. Na parte seguinte aborda as vertentes do processo migratório para formação da dinâmica populacional da Amazônia, assim como do Estado do Acre. Por fim, faz-se uma análise da dinâmica populacional de quatro os projetos de assentamentos ao entorno da cidade de Rio Branco e suas relações com desenvolvimento regional.----------------------------------------------------------------- -------------------------The purpose of this work is to make some considerations on the population dynamics in four projects in the micro settlement of the state of Acre and its implications on regional development, seeking understanding about the economic agents and their relationship with the rural exodus, migration and the influence of aspects of infrastructure exercised by the capital of the state of Acre, Rio Branco. In the first time the study presents the scenario that the regional development transcorre the formation of the new rural Brazil. In part deals with the following aspects of the migration process for formation of the population dynamics of the Amazon, as well as the state of Acre. Finally, it is an analysis of population dynamics of four projects in the settlements around the city of Rio Branco in its relations with regional development.Desenvolvimento regional, dinâmica populacional, Rio Branco, Regional development, Population Dynamics, Rio Branco, Community/Rural/Urban Development,

Muertes aparentes y socorros administrados a los ahogados y asfixiados en las postrimerias

Since de Middle Ages, the fear of being burried alive besets the conscience of many countries in Europe. From its humanistic and philantropical perspective, the XVIII century, yearned by such a misfortune, faced this extremely difficult problem. Initiated in The Netherlands, a large movement of solidarity towards the victims of accidents such as drowned or suffocated people, spread all over Europe. Desperate efforts were made to uphold the victims alive that contributed to successfully rescue a huge number of human beings.Desde la Edad Media, el temor de ser enterrado vivo obsesionó la conciencia de muchos países europeos. El siglo XVIII, de espíritu humanista y filantrópico, conmovido por tan desgraciada suerte, se enfrentó con aquel problema de extrema gravedad. A ejemplo de Holanda, nació por toda Europa un gran movimiento de solidaridad a favor de los ahogados y asfixiados, se desplegaron ingentes esfuerzos para volverlos a la vida, y con indudable éxito, pues se salvó así una infinidad de personas

Implementation and Performance Analysis of a Low Resolution OFDM System Prototype With Low Cost Hardware

The present work focus on the implementation and analyze of performance of a low-resolution OFDM system prototype with low-cost hardware. A software defined radio (SDR) system was chosen in this implementation due to its various advantages over a traditional radio system. Among the options of SDR devices available, the use of universal software radio peripherals (USRP) was avoided due to its high cost, despite its popularity in this field of research. Alternatively, a combination of two low-cost SDRs, "Hackrf One" and "RTL- SDR Blog V3" with the GNU Radio, a popular, free and open source radio software, were used. Thus, it was possible to emulate the behavior of a low resolution ADC in the receiver, characterize its performance and estimate its energy savings. This allowed us to determine the feasibility of building a component with the analog-to-digital conversion function with few bits of resolution. We conclude that the performance of an ADC with at least 5 bits of resolution is pretty reasonable and that this reduction in the number of bits, in comparison to 8-bit ADC, represents a fairly expressive energy saving

Pyrano- und Naphthopyrano[3,2-b]indol-Derivate

Die Pyrano[3,2-b]indole 4a-4c lassen sich durch regioselektive Reaktion des Tetrahydro-3-pyranons (3) mit den Phenylhydrazinen 6a-6c gewinnen, das Naphthopyrano[3,2-b]indol 24 entsteht durch Umsetzung des Naphthopyranons 23 mit 6a. 23 läßt sich aus dem Dihydropyranon 16 und dem Isobenzofuran 21 durch Cycloaddition und Dehydratisierung der so gewonnenen endo/exo-Epoxynaphthopyranone 22a/22b herstellen
