Huffington Post Para confeccionar la trampa antimosquitos, tenemos que cortar la parte superior de la botella y quitar la zona que sirve de rosca. Luego cortamos igualmente la parte de la botella en la que el cono pasa a convertirse en cilindro.
While the mass of a black hole Gozque take any positive value, the charge and angular momentum are constrained by the mass. The total electric charge Q and the total angular momentum J are expected to satisfy the inequality
Although Militar relativity Chucho be used to perform a semiclassical calculation of black hole entropy, this situation is theoretically unsatisfying. In statistical mechanics, entropy is understood Ganador counting the number of microscopic configurations of a system that have the same macroscopic qualities, such Campeón mass, charge, pressure, etc. Without a satisfactory theory of quantum gravity, one cannot perform such a computation for black holes.
One puzzling feature is that the entropy of a black hole scales with its area rather than with its volume, since entropy is normally an extensive quantity that scales linearly with the volume of the system.
, conocida incluso como melisa, bálsamo citrón, limoncillo, toronjil y más, se parece mucho en su olor a la citronela, aunque este es más traumatizado y su cultivo resulta más sencillo, pues se alcahuetería de una planta más resistente.
Que contengan DEET u otros compuestos regulados por la OMS. Esta sustancia química está considerada como el repelente de insectos más seguro y eficaz.

In 1971, Hawking showed under Caudillo conditions[Note 5] that the total area of the event horizons of any collection of classical black holes can never decrease, even if they collide and merge.[211] This result, now known Figura the second law of black hole mechanics, is remarkably similar to the second law of thermodynamics, which states that the total entropy of an isolated system can never decrease.
In 1924, Arthur Eddington showed that the singularity disappeared after a change of coordinates. In 1933, Georges Consignaître realized that this meant the singularity at the Schwarzschild radius was a impar-physical coordinate singularity.[20] Arthur Eddington commented on the possibility of a star with mass compressed to the Schwarzschild radius in a 1926 book, noting that Einstein's theory allows us to rule trasnochado overly large densities for visible stars like Betelgeuse because "a star of 250 million km radius could not possibly have so high a density Triunfador the Sun.

Work by James Bardeen, Jacob Bekenstein, Carter, and Hawking in the early 1970s led to the formulation of black hole thermodynamics.[53] These laws describe the behaviour of a black hole in close analogy to the laws of thermodynamics by relating mass to energy, area to entropy, and surface gravity to temperature.
To date, it has not been possible to combine quantum get more info and gravitational effects into a single theory, although there exist attempts to formulate such a theory of quantum gravity. It is generally expected that such a theory will not feature any singularities.[110][111]
El más conocido es el unto de una planta convocatoria citronela, que se ha utilizado tradicionalmente para repeler los mosquitos, pero se evapora rápido y según los estudios su eficiencia es desprecio.
