Hay Menos Delincuencia entre Venezuela y Colombia

Los relaciones entre las gobiernos de Venezuela y Colombia han estado un poco frio estos ultimos meses. Hay muchas razones para este congelación pero mucho tiene que hacer con la frontera entre las dos paises. En un lado, tienes el gobierno Colombiano diciendo que rebeldes como FARC usan territorio Venezolano para descansar y rearmar y que los Venezolanos hacen nada para parar esto. En el otro lado, tienes el gobierno de Venezuela diciendo que hay contrabandistas y personas cruzando la frontera para vender cosas como comida y artículos de primera necesidad y que esto está lastimando la economía de Venezuela. A pesar de todo los razones, los dos países no son amigos y casi empezaron una guerra.

Mapa de la frontera: Colombia-Venezuela

Ahora, en noticias que sorprenderá personas siguiendo los relaciones entre los dos países, hay un sentido que el peor ha pasado y que hay un chance que los dos países serán amigos en el futuro, si no más temprano. Unos meses pasado, Venezuela desplegó sus fuerzas armadas en la frontera de los dos países para ayudar con los problemas de crimen por todo la frontera. Esto fue un problema con Colombia porque los gobiernos de los dos países no hablaron sobre esto y Colombia sentio como esto fue un violación de su soberanía.

Ahora mira cómo este movimiento por el gobierno de Venezuela fue un buen idea. Informes dicen que crimen y contrabando ha caído por más que 10% en la frontera y los dos países dicen que fue la cosa mejor para hacer. Nadie esta diciendo que Venezuela y Colombia serán mejores amigos en algunos días, pero relaciones son mucho más caliente entre los países y esto es bueno para la región y también para todo América del Sur.

Escasez de Cerveza en Venezuela

Debido a la falta de cebeda, la cervecería más grande de Carlos arias delgado polarVenezuela, Empresas Polar, está cerrando fábricas.  Ayer la federación de cerveceros anunciaron que Empresas Polar cerraría dos de su seis fábricas.  Polar distribue la mayoría de la cerveza en Venezuela.  Soldados venezolanos ocuparon un almacén de Polar y Nestle en Caracas, hablando que necesitan el almacén para albergar los pobres.

Venezuela está sufriendo tres dígitos de inflación, y una escasez de comida, aceite de cocina, azucar y papel higiénico.  Empresas hablan que es la culpa de socialismo, y el gubierno habla que es una “guerra económica”.  El cerrando de fábricas, anunciado ayer, puede afectar un cuarto de producción de cerveza en Venezuela.  La federación de cerveceros habló que las fábricas puedan reabrir tan pronto como el próximo mes, pero nadie sabe si tengan razón.  Presidente Maduro acusó Polar de saboteando la economia por acaparamiento de productos, pero Polar negó las acusaciones.

Polar también está disputando con trabajadores sindicalizados, que quieren aumentos de sueldo.  Trabajadores de decenas de sindicatos representandos trabajadores de Polar cerraron fábricas y limitaron distribución de sus botellas pequeña, que son bastantes populares en Venezuela.  Ahora no hay signos de escasez, pero la cervecería habla que está luchando para entregar cerveza en las regiones centrales de Venezuela.  Esta mez, el jefe de la federación de tienda de licores advirtió que Venezuela puede acabarse cerveza, porque cerveceros llegaron “la hora cero” con un escasez de materiales.  Después, el jefe estaba arrestado por razones no reveladas.

Venezuela-Guyana Dispute

A couple days ago, Venezuelan President Nicolas Maduro demanded that neighboring Guyana cease oil exploration in what is disputed offshore territory, calling it a “dangerous political provocation”.  The region, west of the Essequibo River, has served as a bone of contentment between Venezuela and Guyana, and before that Venezuela and Britain (Guyana was previously a British colony) since the 19th century.  While originally claimed by Venezuela after the country gained its independence in the early 19th century, the region was also claimed by the British, who needed territory in South America to serve trade sailboats on their trading route around South America.  Back in 1899 an international tribunal ruled that the region belonged to Guyana, which at the time was a British colony.  However, Venezuela has insisted that the tribunal was a sham acted out improperly by European judges, and have disputed its legality ever since.

Carlos Arias Delgado EssequiboLate last May, ExxonMobil announced a significant oil discovery in the area, prompting Maduro to issue a presidential decree claiming sovereignty over the waters around the disputing region.  At the same time, the newly elected Guyanese President, David Granger, released a statement where he denounced the decree as a “flagrant violation” of international law, as well as accusing Venezuela of trying to “trample on the rights” of the much smaller Guyana.  Granger insisted that Guyana would continue to develop the offshore natural resources that it considered its own.

Back on Tuesday, Maduro blamed ExxonMobil for the diplomatic row, and advised Guyana to not take “bad advice” from the company or any of its affiliates.  With dialogue and diplomacy, he insisted, Venezuela and Guyana should be able to come to an agreement.  It’s hardly surprising that Venezuela would denounce ExxonMobil; relations between the two have been tense since 2007, after the country’s then-President Hugo Chavez nationalized the company’s assets in Venezuela.  Last year, an international arbitration ruled in favor of ExxonMobil, saying that Venezuela needs to pay them $1.6 billion in compensation for expropriated assets.

Lonely Old Stars

Many of the stars in the Universe live with companions by their sides in so-called “binary systems”.  In these binary systems, two stars orbit around their common center of gravity.  Suitable binary systems are extremely important in astrophysics, since their properties can be inferred with unparalleled accuracy from detailed analysis of their orbital properties.  Oddly enough, however, a huge majority of the known members of the RR Lyrae variable star family have lived their lives alone.  These stars, the oldest known stars in the cosmos, contain vital information about the origin and evolution of the stellar systems that host them, including the Milky Way itself.  However, a lack of RR Lyrae stars in binary systems has made directly Carlos Arias Delgado RR Lyraeassessing some of their key properties extremely difficult, and theory frequently has to be invoked to fill the gap.

The solitude of these stars has always puzzled astronomers.  Now, however, an international research team led by the Millennium Institute of Astrophysics (MAS) and the Pontificia Universidad Catolica de Chile’s Institute of Astrophysics (IA-PUC) have discovered that these stars may not hate companionship as much as previously thought.  The team reported on identification of as many as 20 candidate binaries for RR Lyrae, an increase of up to 2000% from previous tallies.  Twelve of these candidates have enough measurements to conclude that they do indeed consist of two stars orbiting each other.  In their paper, the authors used a method that astronomers call the “light-travel time effect”, which exploits subtle differences in time that it takes starlight to reach us.  The RR Lyrae stars pulsate regularly, significantly increasing and then decreasing their sizes, temperatures and brightness in just a few hours.  When a pulsating star is in a binary system, the changes in brightness that we perceive can be affected by where the star is in the course of its orbit around the companion.  This means that starlight takes longer to reach us when it’s at the farthest point along its orbit, and vice-versa.

The researchers’ measurements were based on data published by the Polish OGLE Project, who has obtained their data using the 1.3m Warsaw telescope in Las Campanas Observatory in northern Chile, repeatedly observing the same patches of the sky for many years.  The 20 binary candidates were found analyzing the roughly 2000 best observed RR Lyrae stars towards the central parts of the Milky Way, making up about 5% of the known ones.  Only thanks to the high quality of the OGLE data and long timespan of these observations that the researchers could finally find signs of companions around so many of these stars.

Indeed, the systems detected by researchers have orbital periods of several years, indicating that the companions aren’t very close to one another, even though they’re bound together by gravity.  Binaries with even longer periods could also exist, but the current data doesn’t extend long enough for researchers to reach strong conclusions about them.  The researchers have pointed out that these results have significant implications for astrophysics; these are extremely old stars that have witnessed the formation of galaxies.  They’re also easy to identify, since they show characteristic, cyclical brightness variations that make them excellent distance indicators for the nearby Universe.  Now, researchers can exploit the orbital information contained in these binary systems in order to directly measure their physical properties, especially their masses but maybe their diameters as well.  This could open new doors to discoveries that had previously seemed impossible.
