Lagunas de Cotacotani

Las lagunas de Cotacotani (en aimara: quta-qutani‘conjunto de lagunas’)? son múltiples lagunas ubicadas en el altiplano andino de la comuna de Putre, Provincia de Parinacota, al extremo oriente de la Región de Arica y Parinacota waterproof pouch for swimming, Chile. Se encuentra a 4 km al noroeste del lago Chungará, siendo uno de los más altos del mundo. Está rodeado por diversas cumbres nevadas, como el conjunto de los nevados de Payachatas, compuestos por los volcanes Parinacota y Pomerape, el nevado Sajama y el Guallatiri how do you use meat tenderizer.

Las lagunas de Cotacotani se encuentra separadas por rocas volcánicas ubicadas en el Chungará y recibe aguas de este lago en forma subterránea, pero es abastecido principalmente por el río Desaguadero. Su principal característica es el gran número de islas e islotes que se localizan en las lagunas, debido a que estas son protuberancias de lava generadas por el activo volcanismo de la zona. Con una superficie de 6 km², las lagunas tienen un volumen almacenado de entre 30 a 40 millones de m³, los cuales desaguan, a través del río Lauca al lago Coipasa, en Bolivia.

Está inmerso en el Parque Nacional Lauca running water belt reviews. Junto a las lagunas se encuentran una serie de bofedales, entre los que destaca el bofedal de Parinacota. Las lagunas poseen una rica fauna waterproof phone case, única y variada con más de 130 especies nativas, en las que destacan flamencos y patos. Se accede mediante la Ruta 11-CH desde Arica.

Ludwig Struve

Gustav Wilhelm Ludwig Struve (November 1, 1858 – November 4, 1920) was a Russian astronomer, part of the famous Baltic German Struve family. In Russian, his name is sometimes given as Lyudvig Ottovich Struve (Людвиг Оттович Струве) or Lyudvig Ottonovich Struve (Людвиг Оттонович Струве).

Gustav Wilhelm Ludwig Struve was born in 1858 in Tsarskoye Selo – a former Russian residence of the imperial family and visiting nobility, located 26 kilometers (16 mi) south from the center of St. Petersburg. He was the fourth son of Otto Wilhelm von Struve and Emilie Dyrssen (1823–1868) and a younger brother of astronomer Hermann Struve. Gustav followed his family traditions and between 1876 and 1880 studied astronomy at the University of Tartu. For his post-graduate research started at the Pulkovo Observatory which was headed by his father. In 1883, Gustav defended his PhD thesis on “Resultate aus den in Pulkowa angestellen Vergleichungen von Procyon mit benachbarten Sternen” (Results obtained in Pulkovo on relation of Procyon with the neighboring stars). Between 1883 and 1886 best ball shaver, Struve was staying abroad in several European observatories, including those in Bonn, Milan, Paris and Leipzig. His major influences in astronomy were his father and the Italian astronomer Giovanni Schiaparelli. Between 1886 and 1894, Struve worked as an astronomer at the Tartu Observatory. In 1887, using results obtained during his European trip, he prepared and defended the habilitation thesis titled “Neue Bestimmung der Constante der Precession und der eigenen Bewegung des Sonnensystems” (New determination of the constant of precession and of the motion of the Solar System).

A few years after retirement of his father, in 1894, Gustav moved to the University of Kharkov. There, in 1897 he became professor in astronomy and geodesy and director of the observatory. Prior to Struve, the Kharkov Observatory was not registered within the Russian leveling network and the altitude of Kharkov was based on rather inaccurate trigonometric leveling conducted by local triangulation. It took Struve five years of hard work to include the observatory to the Russian leveling network. In 1912, he was elected as Dean of the Physics and Mathematics Department of Kharkov University. In 1914, he founded a workshop of fine mechanics at the department and headed it for five years. Prior to that, such institutions had been nonnexistent in Russia, and foreign engineers were personally invited for precision mechanical work. Struve attempted to build a national school in this area, but with limited success. He himself was a skilled engineer and constructed an instrument for the measurement of “an individual error using artificial star.” This device was invented by H. G. van de Sande Bakhuyzen at the Leiden Observatory and was actively used by Struve.

Struve’s research was first focused on celestial mechanics, in particular precession and other motion within the Solar System. It then expanded on the study of the positions and motion of stars, in particular single and double stars lying within the angular range of the Tartu Observatory. He used occultation of stars by the Moon to refine the value of the lunar radius. He also determined the apex coordinates of the Sun’s movement and was one of the first astronomers to estimate, in 1887, the rotation rate of the Milky Way.

On the basis of his observations in Kharkov, Struve compiled a catalogue “Observation of 779 zodiac stars” (1898–1902). Between 1908 and 1915, Struve with collaborators determined right ascension and declination of 1407 circumpolar stars, taking about 11,000 observations for each coordinate. The results were published in the “Kharkov differential catalogue of declination of 1407 circumpolar stars in FK4 system for mean epoch of 1911 year” and “The results of a comparison of the catalogue of declination of 1407 circumpolar stars and the Fabritius catalogue with the tables of proper motion of 412 circumpolar stars”.

Struve was married to Elizaveta Khrystoforovna (1874–1964) and they had two sons and two daughters. Their first child, son Otto, was born in Kharkov in 1897, and later became one of the most famous astronomers of the 20th century. Later, Otto served as a White Russian officer in the losing side of the civil war that followed the Russian Revolution. Therefore, to avoid Bolshevik’s repressions how do you use meat tenderizer, Struve had to move in 1919 to Simferopol where he had assumed professor position at the Tavria University. He left in Kharkov a collection of about 1400 historical letters involving his father and grandfather, Friedrich Georg Wilhelm von Struve. The collection had survived two wars and was preserved till the present days.

After leaving Kharkov, life of the Struve turned tragic. In summer of 1920, his 9-year-old daughter Elizabeth drowned in front of him. Later, his son Werner (1903–1920) died from tuberculosis. Soon after electric shaver balls, Struve himself died of a stroke. He was survived by his wife and daughter Yadviga (1901–1924). They returned to Kharkov. Yadviga had taught German at Kharkov Technology Institute, but died in 1924 of tuberculosis.

In 1915 thermos water, Struve received an award from the council of the Russian Astronomical Society, where he was a member from 1893. The award was given for his work “Elaboration of the observations of lunar occultation of the stars during the total lunar eclipse” that was carried within a collaboration between the Kharkov and Pulkovo observatories.
