1. Sistema para análise das outorgas de captação de água e diluição de efluentes na bacia do rio Piracicaba (MG)
RESUMO A outorga de direito de uso da água é um dos principais instrumentos de gestão para controle quantitativo e qualitativo dos recursos hídricos. Para sua implantação, é necessário, entre outras ações, definir critérios e desenvolver ferramentas para análise integrada dos aspectos quantitativos e qualitativos da água. Dessa forma, o objetivo

2. Numerical study of upstream disturbances on the performance of electromagnetic and ultrasonic flowmeters
ABSTRACT Electromagnetic and ultrasonic flowmeters are high precision devices that can measure the water flow in pressurized irrigation networks. In these networks, the inadequate installation distance of flow control valves generates upstream disturbances which will increase measurement errors and reduce the accuracy of the equipment. Therefore, estimating

3. Análise comparativa entre torneira convencional e torneira de funcionamento hidromecânico instaladas em um campus universitário
Resumo Quando se trata de uso racional da água, a substituição de equipamentos hidrossanitários convencionais por economizadores de água é uma prática comum nas edificações de uso público. Neste artigo é apresentada uma comparação entre duas torneiras de lavatório, uma convencional com registro de pressão e outra de funcionamento hidromecânic

4. Effect of lectin (ScLL) on fibroblasts stimulated with LPS - an in vitro study
Abstract: The lectin (ScLL) extracted from the Synadenium carinatum plant has been evaluated as an immunomodulator in diseases such as asthma, neosporosis and leishmaniasis. However, it has not yet been evaluated in the oral cavity. This study evaluated the effect of ScLL on viability, proliferation and release of IL-10 in human gingival fibroblasts (HGF) st

5. LOW COST ANALYZER FOR THE DETERMINATION OF PHOSPHORUS BASED ON OPEN-SOURCE HARDWARE AND PULSED FLOWS
The need for automated analyzers for industrial and environmental samples has triggered the research for new and cost-effective strategies of automation and control of analytical systems. The widespread availability of open-source hardware together with novel analytical methods based on pulsed flows have opened the possibility of implementing standalone auto

6. Uso de hardware de código fonte aberto "Arduino" para acionamento de dispositivo solenoide em sistemas de análises em fluxo
This paper describes the use of the open source hardware platform, denominated "Arduino", for controlling solenoid valves for solutions handling in flow analysis systems. System assessment was carried out by spectrophotometric determination of iron (II) in natural water. The sampling rate was estimated as 45 determinations per hour and the coefficient of var

7. Prediction of the temperature distribution of partially submersed umbilical cables
The objective of this work is to predict the temperature distribution of partially submersed umbilical cables under different operating and environmental conditions. The commercial code Fluent® was used to simulate the heat transfer and the air fluid flow of part of a vertical umbilical cable near the air-water interface. A free-convective three-dimensional

8. Produção e caracterização de espumas cerâmicas obtidas a partir de lodo de anodização de alumínio
Ceramic foams were produced from a sludge generated in the aluminum anodizing process by using an industrial polyurethane foam (replication method) with open cell sizes of 10 ± 5 ppi (porosity = 97%) which were impregnated with suspensions containing 50-61 wt.% alumina, 1 wt.% citric acid, 6 wt.% bentonite and fired at 1600 ºC for 2 h. The aluminum anodizi

9. Cibersegurança em sistemas de automação em plantas de tratamento de água. / Cibersecurity in automation systems in water treatment plants.
Currently, information security is a constant concern of the several institutions and countries that use computing resources for communication and service offering purposes. Protection methods and countermeasures for traditional networks such as firewalls and intrusion detectors are known and ordinarily used. The same goes for control systems and data acquis

10. Monitoring of potassium in a culture of irrigated bell pepper in semiarid region / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoring of potassium in a culture of irrigated bell pepper in semiarid region / Monitoring of potassium in a culture of irrigated bell pepper in semiarid region
The bell pepper is of high importance within the vegetable crops, thus becoming an alternative source of income for small producers and family farms. Potassium is the nutrient most absorbed by bell pepper and diffusion the main transport mechanism to the roots, although the mass flow can have significant contribution in the process under high potassium conce

12. A influencia do diametro representativo do material do leito nas formulas de calculo do transporte de sedimentos em escoamentos com superficie livre / The influence of representative diameter of the bed material load in the formulae for calculating the sediment transport in free surface flows
Nesta tese apresenta-se uma alternativa à definição do diâmetro de cículo a ser usado nas equações de estimativa da descarga de sedimentos na camada do leito, em escoamento com superfície livre. Foram empregadas quatorze equações de estimativa da descarga de sedimentos, a partir das quais foram determinados os diâmetros que poderiam ser empregados
