2. MODELING AND ANALYSIS OF UNSTEADY FLOW BEHAVIOR IN DEEPWATER CONTROLLED MUD-CAP DRILLING
Abstract A new mathematical model was developed in this study to simulate the unsteady flow in controlled mud-cap drilling systems. The model can predict the time-dependent flow inside the drill string and annulus after a circulation break. This model consists of the continuity and momentum equations solved using the explicit Euler method. The model consider

4. The 3D CFD study of gliding swimmer on passive hydrodynamics drag
The aim of this study was to analyze the effect of depth on the hydrodynamic drag coefficient during the passive underwater gliding after the starts and turns. The swimmer hydrodynamics performance was studied by the application of computational fluid dynamics (CFD) method. The steady-state CFD simulations were performed by the application of k - omega turbu

5. Reproductive biology of the coypu, Myocastor coypus (Rodentia: Myocastoridae) in western Japan
We describe the reproductive biology of the coypu, Myocastor coypus (Molina, 1782), in western Japan, as an attempt to contribute to an efficient population control program of the coypu population. A total of 212 specimens (113 males and 99 females) were collected in the Tottori prefecture from February 2010 to January 2012. From the age estimation based on

6. Time-frequency analysis of Hilbert spectrum of pressure fluctuation time series in a Kenics Static Mixer based on empirical mode decomposition
The turbulent flow in a Kenics Static Mixer (KSM) was intensified under the mutual-coupling effect between the twisted leaves and the tube-wall. In order to understand the intrinsic features of turbulent flow in KSM, the Hilbert-Huang Transform based on Empirical Mode Decomposition were first introduced to describe the time-frequency features of the pressure

7. FLUTUAÇÃO DOS NÍVEIS DE ÁGUA SUBTERRÂNEA EM MICROBACIAS HIDROGRÁFICAS DO RIO VACACAÍ-MIRIM / GROUNDWATER LEVELS FLUCTUATION IN VACACAÍ-MIRIM RIVER SMALL WATERSHEDS
The intention in this work is to study (locally) the fluctuation system of groundwater levels in two small watersheds. We selected Rancho do Amaral and Rincão do Soturno small watersheds for being representative of the first order streams which compose the Vacacaí-Mirim river watershed headwaters. Both are located at the border of Paraná Sedimentary Basin

8. ANÁLISE DE DESEMPENHO EM TRAÇÃO DE RODADO SIMPLES E DUPLO EM UM TRATOR AGRÍCOLA / ANALYSIS OF TRACTION PERFORMANCE OF SINGLE AND DUAL TIRES IN AN AGRICULTURAL TRACTOR
A major problem of agricultural tractor during several operations in which it is used is the difficulty of working in various moisture conditions and soil types affect your ability to traction force, slip and fuel consumption. What has been observed is that with increased contact surface between the tire of the tractor and the ground, there is the possibilit

9. Correlation between central corneal thickness and intraocular pressure peak and fluctuation during the water drinking test in glaucoma patients
OBJECTIVE: To investigate the correlation between central corneal thickness and outflow facility assessed by intraocular pressure peak and fluctuation during the water drinking test. METHODS: Fifty-five newly diagnosed primary open-angle glaucoma patients submitted to central corneal thickness measurements and water drinking test were enrolled in this retros

10. Identification of defluidization region in a gas-solid fluidized bed using a method based on pressure fluctuation measurements
Industrial applications that involve fluidized bed operations must prevent the undesirable phenomenon of partial or complete bed defluidization. Defluidization can be avoided by increasing the gas velocity and/or, in some cases, changing the solid feed conditions in the system, provided that the changes in the hydrodynamics of the flow are detected early eno
