Portugal atravessava uma crise social, econômica e política no início do século XX. Após o regicídio do rei D. Carlos em 1908, o descontentamento popular continuou a crescer, liderado por grupos como a Carbonária e o Partido Republicano. Finalmente, a noite de 4 de Outubro de 1910 eclodiu a Revolução Republicana, que derrubou a Monarquia e proclamou a República em Portugal.
Thermal instability of incompressible non newtonian viscoelastic fluid with...eSAT Journals
1) The document summarizes a study on the thermal instability of incompressible, non-Newtonian viscoelastic fluids under the effects of rotation and magnetic fields.
2) Key findings include that rotation has a stabilizing effect on the fluid, while the magnetic field can have both stabilizing and destabilizing effects.
3) The study found that rotation and magnetic fields introduce oscillatory modes into the system that were not present without their effects. Graphs were presented showing the relationships between stability and the rotation and magnetic field parameters.
PHYSIOLOGICAL NON-NEWTONIAN BLOOD FLOW THROUGH SINGLE STENOSED ARTERYIwate University
Abstract. A numerical simulation to investigate the Non-Newtonian modeling effects on physiological flows in a three dimensional idealized artery with a single stenosis of 85% severity is given. The wall vessel is considered to be rigid. Oscillatory physiological and parabolic velocity profile has been imposed for inlet boundary condition. Determination of the physiological waveform is performed using a Fourier series with sixteen harmonics. The investigation has a Reynolds number range of 96 to 800. Low Reynolds number k − ω model is used as governing equation. The investigation has been carried out to characterize two Non-Newtonian constitutive equations of blood, namely, (i) Carreau and (ii) Cross models. The Newtonian model has also been investigated to study the physics of fluid. The results of Newtonian model are compared with the Non-Newtonian models. The numerical results are presented in terms of velocity, pressure, wall shear stress distributions and cross sectional velocities as well as the streamlines contour. At early systole pressure differences between Newtonian and Non-Newtonian models are observed at pre-stenotic, throat and immediately after throat regions. In the case of wall shear stress, some differences between Newtonian and Non-Newtonian models are observed when the flows are minimum such as at early systole or diastole. In general, the velocities at throat regions are highest at all-time phase. However, at pick systole higher velocities are observed at post-stenotic region. Downstream flow of all models creates some recirculation regions at diastole.

The document summarizes the key news and events from the September 6th, 2013 issue of the Business Council of Mongolia NewsWire. It discusses several business and economic stories, including Rio Tinto replacing board members at the Oyu Tolgoi copper mine amid disputes with the Mongolian government over financing. It also mentions Erdenes Tavan Tolgoi planning to ramp up coal production and begin exports from its West Tsankhi mine. Additionally, it provides an overview of the 2013 Discover Mongolia investment forum, including remarks on the importance of respecting investment agreements and concerns about policy instability expressed by speakers from Anglo American and Erdenes Tavan Tolgoi.

This document summarizes a workshop on Behavior-Driven Development (BDD) for Rich Internet Applications (RIAs) with JavaScript. It outlines the BDD process, which involves specifying user stories and acceptance criteria, writing scenarios to define desired behavior, and using an outside-in approach with test-driven development. It emphasizes writing unit tests with test doubles before integrating components. The workshop includes exercises for connecting a business API to a service with unit tests, connecting the UI to the service, implementing the service and interactor, and implementing a textbox widget with integration tests. It also discusses architecture patterns like passive view and reviewing non-functional requirements.

Simulation of pressure drop for combined tapered and nontapered die for polyp...IOSR Journals
Abstract: the pressure drop in combined sections tapered and circular for the flow of polypropylene were
studied both analytical and simulation under isothermal and no-slip condition in the die wall. The predicted
pressure drop values are compared with three-dimensional (3D) finite element simulation to identify effect of
contraction angles, die land and radius on pressure drop. The governing equation of pressure drop was first
derived to angle of tapered section, for circular section the pressure drop was studied using different die lands
and radii .The three parameters were varied in the ansys Polyflow at specified polymer flow rate and the results
are compared with analytical results .For the tapered section the best angle is analytically and for
the simulation. For circular section of the die the results for die lands variations are almost the same but when
varying the varying the radius the results differ at radii less than 2 cm and approach each other at 2 cm and
above. Index Terms: Tapered die, circular section, pressure drop, Polyflow.
