1. 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

2. Effect of sawdust as porosity agent on final properties of geopolymers
Abstract The geopolymers synthesis are based on geopolymerization, a sequence of reactions processed in an alkaline medium through oligomers providing a three-dimensional molecular structure. In this work, the polycondensation of metakaolin was performed with alkaline activators (NaOH and sodium silicate), wood sawdust and other additives. Two different comp

3. Effects of quinoa flour on lipid and protein oxidation in raw and cooked beef burger during long term frozen storage
Abstract The objective of this work was to assess the effects of quinoa flour in the improving the quality characteristics and oxidation and storage stability (-18 °C for 3 months) of cooked and raw beef burger. The effects of quinoa flour addition (3, 5, 7 and 10%) on physicochemical composition, pH, cooking parameters and dimensional changes, color and t

4. A Comparative Study of Cartesian and Delta 3D Printers on Producing PLA Parts
The additive manufacturing processes emerged at the end of the last century and became popular by low-cost 3D printers. The most used printers work on a cartesian configuration, but recently were launched delta machines. These 3D printers use a more complex control system due to their trajectories generation but may present some advantages over the cartesian

5. Candida albicans PROTEIN PROFILE CHANGES IN RESPONSE TO THE BUTANOLIC EXTRACT OF Sapindus saponaria L.
Candida albicans is an opportunistic human pathogen that is capable of causing superficial and systemic infections in immunocompromised patients. Extracts of Sapindus saponaria have been used as antimicrobial agents against various organisms. In the present study, we used a combination of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and matri

6. Three-dimensional reconstruction of compacted graphite in vermicular cast iron by manual serial sectioning
Microstructural characterization is an important tool to optimize the properties of engineering materials. Metallography is a common technique, but it provides two-dimensional images from (sometimes complex) three-dimensional microstructures. Three-dimensional reconstruction of microstructures provides more precise informa tion on the morphologies of the mat

7. Domínios ferroelétricos em cerâmicas e materiais nanoestruturados: investigação por microscopia de piezoresposta
In this work, ferroelectric domain structure was investigated by Piezoresponse Force Microscopy (PFM). To this, an Atomic Force Microscope (AFM) has been modified to use it as PFM at room temperature and at high temperatures. Ferroelectric ceramics were used in the as bulk ceramic samples of Pb(Zr0,40Ti0,60)O3 (PZT 40/60) and (Pb0,79La0,21)TiO3 (PLT 21) prod

8. Análise numérica 3D do túnel auxiliar a jusante da UHE simplício-anta / 3D Numerical analysis of the tunnel downstream of the auxiliary
With the accelerated occupation of the space, the use of tunnels play an important role in engineering, in this sense, the deformations control during it s construction process is very important for the best performance of tunnels. In this sense the numerical analyzes represent a likely economy in the design process. This paper uses a theory of elasticity in

9. Desenvolvimento de métodos cromatográficos hifenados (in-tube SPME/LC-FLD e GCxGC/qMS) para análises de fármacos e agrotóxicos em amostras complexas / Development of hyphenated chromatographic methods (in-tube SPME/LC-FLD and GCxGC/MS) for analysis of drugs and pesticides in complex samples.
Determination of trace levels of drugs in biological fluids and multiresidue (contaminants) in food samples is extremely important because this generates valuable data for therapeutic drug monitoring (individualization of dosage regimen) and quality control (food safety), respectively. Because of the demand for analytical methods with high resolution and low

10. Fear, anxiety and their disorders: past, present and future neural theories
This paper reviews the historical development of a two-dimensional (direction x distance (?)) neural model of defense. It begins with Miller's (1944) analysis, and model, of approach, avoidance and conflict; adds Hinde's (1966) ethological perspective and Flynn's (1967) neural model of fear; and then considers Gray's (1967, 1970) work linking barbiturate act

11. Evaluation of a computer model to simulate water table response to subirrigation.
The objective of this work was to evaluate the water flow computer model, WATABLE, using experimental field observations on water table management plots from a site located near Hastings, FL, USA. The experimental field had scale drainage systems with provisions for subirrigation with buried microirrigation and conventional seepage irrigation systems. Potato

12. Efeitos causados pela modulação de parâmetros no mapa de hénon / Effects caused by the parameters modulation in the hénon map
The Hénon map is a paradigmatic two-dimensional discrete-time dynamical system, which was originally proposed as a model to the Poincaré section of the continuous-time Lorenz system, and has been extensively investigated in the last years. Apart from its theoretical importance, some practical applications are possible. As an example, it can be used to mode
