Multivariate factorial analysis to design a robust batch leaching test to assess the volcanic ash geochemical hazard
No full textA method to obtain robust information on short term leaching behaviour of volcanic ashes has been developed independently on the sample age. A mixed factorial design (MFD) was employed as a multivariate strategy for the evaluation of the effects of selected control factors and their interactions (amount of sample (A), contact time (B), and liquid to solid ratio or L/S (C)) on the leaching process of selected metals (Na, K, Mg, Ca, Si, Al, V, Mn, Fe, and Co) and anions (Cl - and SO 4 2-). Box plots of the data acquired were used to evaluate the reproducibility achieved at different experimental conditions. Both the amount of sample (A) and leaching time (B) had a significant effect on the element stripping whereas the L/S ratio influenced only few elements. The lowest dispersion values have been observed when 1.0g was leached with an L/S ratio equal to 10, shaking during 4h. The entire method is completed within few hours, and it is simple, feasible and reliable in laboratory conditions.Fil: Ruggieri Flavia. Consejo Superior de Investigaciones Científicas.

The political and military career of General Anastasio Bustamente (1780-1853)
No full textAnastasio Bustamante was born in the modern day state of Michoacan in
1780. He served the Royalist Army during the insurgency (1810-1821). He was one
of the first officers to adhere to Agustin de Iturbide's Plan of Iguala in 1821, and a
signatory of the Act of Independence (28 September 1821). He was a member of
Mexico's first independent government, the Junta Provisional Gubernativa (1821-
1822) and served as the Captain General of the Eastern and Western Internal
Provinces during Iturbide's short-lived reign as Emperor (1822-1823). He served as
the Commander General of the Eastern Interior Provinces between 1826 and 1829. In
1829 he became Vice-President of the Republic. In December 1829 he led a
successful rebellion against the incumbent President, Vicente Guerrero. He served as
acting Head of the Executive between 1830 and 1832. In 1837 he was elected
President. He occupied this position until 1841. He commanded the troops of the
Western Division during the war with the United States (1846-1848). Between 1848
and 1849, he oversaw the pacification of one of the many rebellions of the Sierra
Gorda (now the Sierra de Queretaro). He died in Guanajuato in 1853, aged 73.
This study examines Bustamante's military and political career. It rejects the
traditional interpretation of the General, which portrays him as a weak and indecisive
man lacking in any real political principles. Instead, it argues that Bustamante was a
resolute and pragmatic leader, who supported the cause of moderate federalism for
most of his career
