Layout-Oriented Design of a 60 GHz Power Amplifier in SiGe Technology
Sette, Elmo Luiz FechineThis work presents the design of a fully integrated cascode single-stage power amplifier for 60 GHz band. The technology used in the design was Global Foundries SiGe of 0.13µm (BiCMOS8HP). A load-pull analysis of the cascode was done including optimization of the bias and geometry parameters aiming at finding the best performance of this topology. A layout-oriented design approach was adopted to decide upon differ...
Isolamento do ruído de impacto entre pisos de unidades habitacionais sobreposta...
Xavier, Leilane de Aguiar AlmeidaThe requirements concerning of insulation the noise levels of impact in the system of floors between adjacent units of multi-storey residential buildings in Brazil, were established in the Performance Standard, NBR 15575-3 (ABNT, 2013). Since then, new construction must conform to the limits set by performing three ranges: low (between 66 dB and 80 dB), intermediate (between 56 dB and 65 dB) and upper (less tha...
Sistemas individuais alternativos de tratamento de esgoto sanitário
Carneiro, Mariko de AlmeidaWHO (2017b) estimates that 4.5 billion people in the world do not have access to safe sanitation services. The context is not very different in Brazil, where despite significant advances in the sanitation sector, only, 51,9% of the Brazilian population has access to sewage service and 44,9% of the sewage generated in the country suffer some type of treatment (SNIS, 2018). In order to increase sanitation service...
Análise espaço-temporal da reflectância e estimativa de sedimentos em suspensão...
Rocha, Victor Nathan Lima daArtificial reservoirs of water - regionally known as açudes (dams) - are essential sources for the supply of water, especially in semiarid climate regions, wich are susceptible to shortages, as is the case in the Cariri region. The Açude Epitácio Pessoa (or Boqueirão) is notably relevant in socio-economic and environmental context, supplying around a million inhabitants of 19 cities and 3 districts of the Paraí...

Vilar, Welma Thaíse SilvaThe Aedes aegypti mosquitoes are vectors of diseases such as dengue, chikungunya, zika and yellow fever. With the increase in the incidence of these diseases, the population has resorted to the use of repellents to try to protect themselves from the attack of these mosquitoes. The Brazilian market offers a wide variety of products which have different active ingredients (with varying levels of concentration), p...
O processamento da anáfora se em português brasileiro: comparando dados de Mina...
Lacerda, Maria Claudia MesquitaEl objetivo de esta investigación fue investigar si diferentes tipos de recuperación [si, Ø, él (a)] pueden influir el procesamiento correferencial de estructuras reflexivas. Con la finalidad de comprobar si la variación dialectal del uso de la anáfora si (supresión, duplicación, inserción y sustitución) podría influir en el procesamiento de estas estructuras, fue realizado un experimento de lectura automonitor...
Alimentação escolar e a produção de resíduos orgânicos na rede municipal de ens...
Ribeiro, Lázaro Fialho da CruzSchools with Integral Education are establishments where students stay for more than one shift and carry out activities that go beyond formal education. The number of schools with integral education has been increasing in Brazil associated with governmental programs like "More Education" and "New High School". Considering the provision of three meals a day to students in these educational units, a large amount ...
Patrimônios em devir: a fruição da informação dos patrimônios arqueológicos jun...
Catoira, ThaísThis piece of research aimed to reflect, from the fruition, on the memories and representations evoked by the people that inhabit the surroundings or fulfill activities related to the archaeological sites present in the municipality of Camalaú, in the Cariri of Paraíba, in order to understand through the presented information as these cultural manifestations are perceived. Thus, the concept of cultural heritage...
