The Argentinian blockade of Montevideo was ineffective as Rosas generally tried not to interfere with international shipping on the River Plate, but, in 1845, when access to Paraguay was blocked, Great Britain and France allied against Rosas, seized his fleet, and began a blockade of Buenos Aires, while Brazil joined in the war against Argentina. Rosas reached peace deals with Great Britain and France in 1849 and 1850, respectively. The French agreed to withdraw their legion if Rosas evacuated Argentinian troops from Uruguay. Oribe still maintained a loose siege of the capital. In 1851, the Argentinian provincial strongman Justo José de Urquiza turned against Rosas and signed a pact with the exiled Unitarios, the Uruguayan Colorados, and Brazil against him. Urquiza crossed into Uruguay, defeated Oribe, and lifted the siege of Montevideo. He then overthrew Rosas at the Battle of Caseros on 3 February 1852. With Rosas's defeat and exile, the "Guerra Grande" finally came to an end. Slavery was officially abolished in 1852. A ruling triumvirate consisting of Rivera, Lavalleja, and Venancio Flores was established, but Lavalleja died in 1853, Rivera in 1854, and Flores was overthrown in 1855.

The advance of a vessel through water is resisted by the water. This resistance can be broken down into several components, the main ones being the friction of the water on the hull and wave making resistance. To reduce resistance and therefore increase the speed for a given power, it is necessary to reduce the wetted surface and use submerged hull shapes that produce low amplitude waves. To do so, high-speed vessels are often more slender, with fewer or smaller appendages. The friction of the water is also reduced by regular maintenance of the hull to remove the sea creatures and algae that accumulate there. Antifouling paint is commonly used to assist in this. Advanced designs such as the bulbous bow assist in decreasing wave resistance.
I already have a Vivofit that does my sleep/steps. Can I turn off the steps/sleep on the Vivoactive since I already use the Vivofit for activity tracking? I already use a 910xt for triathlon, so I am just looking for a smartwatch and want to stay in the Garmin ecosystem Also, any word on whether they going to come out with a new version in the Spring 2016? I might decide to wait.
The primary objective of the mission was to perform a long duration flight test of NASA's Super Pressure Balloon (SPB) carrying a scientific payload as a mission of opportunity. The SPB is a pumpkin-shaped sealed structure that is filled with a measured and specific amount of helium lifting gas which always maintains a positive internal pressure in relationship to the environment it is floating in. The balloon is filled with an amount of helium needed to lift the entire flight system plus some extra gas to provide an upward force known as the free lift. Once launched, the balloon ascends but unlike occurs with conventional or so called Zero-Pressure (ZP) balloons when it reaches the desired float altitude, the extra helium is not vented off, but fills out the shape and pressurizes the balloon. This extra helium is enough to pressurize the balloon and also to over-pressurize the balloon to the design limits.The design's shape is an oblate spheroid with a proportion of height of about 60% of the diameter. It is an evolution of the former Ultra Long Duration Balloon (ULDB) project initiated by NASA in early 80's and still is in developmental phase. Is made up of many separate panels or gores that run from top to bottom on the balloon. At the edge of each of these gores is a very strong and light weight tendon or rope that runs from top to bottom on the balloon. Each of these gores are shaped that, while under pressure, have a slightly curved lobed shape. This is why this type of balloon has been called a pumpkin shaped Super Pressure Balloon.Theoretically, the SPB is designed to fly with a positive internal pressure at all times: as the sun heats up the balloon during the day, the internal pressure (differential pressure) increases, and at night when the balloon cools down, the differential pressure significantly decreases, but still above ambient, hence maintaining super pressure condition at all times. The differential pressure range is up to 180 Pa (0.0261 psi). This is a very small internal pressure, but it is enough to keep this balloon flying through the night. As a result of maintaining near constant volume, the SPB offers greater stability at float altitude with minimal altitude excursion during the day/night cycles when compared to that experienced by ZPB balloons. This added stability and extended durations at mid-latitudes will enable new science missions that currently are not feasible with ZP balloons.Description of the scientific InstrumentEUSO-SPB (Extreme Universe Space Observatory for Super Pressure Balloon) is part of a larger project called JEM-EUSO, a new type of observatory to be installed on the Japanese Experiment Module (JEM), a external science module developed by JAXA, which is part of the International Space Station. It will be based on a ultraviolet very large telescope, which uses the whole Earth as detector. It will observe, from an altitude of several hundreds of kilometers, the fluorescence tracks produced at 330-400 nanometers by Extensive Air Showers originated by Ultra High Energy Cosmic Rays which traverse the Earth's atmosphere at ultra-relativistic speed. 16 Countries, 89 Institutes and 311 researchers are collaborating in JEM-EUSO, with the support of the most important International and National Space Agencies and research funding institutions.At present the JEM-EUSO program involves the realization of small different fluorescence detectors already installed or to be installed on ground (EUSO-TA), on board stratospheric balloons for short (EUSO-Balloon) or long duration (EUSO-SPB) flights, inside the International Space Station (Mini-EUSO) and of a much larger detector to be attached outside the ISS (K-EUSO). EUSO-SPB is the second generation of the balloon-based version of EUSO. The first one denominated EUSO-Balloon was flown in August 2014 over Canada in collaboration with the French Space Agency CNES. It was equipped with one full original JEM-EUSO PDM (photon detection module with 2304 pixels) and with an optical system made of two Fresnel lenses, with a side of 1 meter covering a field of view of 6 degrees, which were real prototypes of those foreseen in JEM-EUSO plus a stand-alone and waterproof infrared camera.The EUSO-SPB instrument was an updated version of that same experiment. It included also a full original JEM-EUSO PDM, and an optical system with three Fresnel lenses with a side of 1 meter covering a field of view of 6 degrees, one of them designed to provide chromatic focusing over the UV spectrum of the track. The more significant improvement -besides the engineering adaptation of the whole instrument electronics, command systems and power from a short duration flight profile to a large one- is the inclusion of a new version of the trigger system to "catch" the high energy cosmic ray events. The main scientific objective of the mission was to obtain the first observation and measurements of Ultra High Energy Cosmic Ray Air Showers by looking down from near space with a fluorescence detector; the observation of UV pulse like signatures from other objects as meteoroids, electrical phenomena in the atmosphere and finally the measurement of slow variations of UV light as airglow or bioluminescence even over the ocean.
