The 30,000 km2 province of Luristan is situated in western Iran and encompasses the upper valleys of the Zagros Mountains. Even today, local tribesmen inhabit Luristan with their settlement patterns similar to ancient times. Several scientific excavations in the Luristan region have uncovered evidence that this particular region was a major attraction for human settlements from the Paleolithic era onwards. In Ancient Iran, the existence of rich mines together with discoveries made by innovative and inventive artisans spurred the growth of the metalworking culture as an art and a skill among early human communities in Ancient Iran. The art of Luristan can be described as the art of nomadic herdsmen and horsemen with an emphasis on the crafting of small, easily portable objects, among these a number of bronze daggers, swords and other weapons. Throughout its history, Luristan was never an ethnic or political entity because Luristan has been occupied by various tribes and races, throughout its history. Next to Elamites, other tribes who inhabited Luristan were the Hurrians, Lullubians, Kutians, and Kassites. As local tribesmen of Luristan were illiterate, information about their history can only be partially reconstructed from the literature of their southern neighbors: the Elamites and Babylonians. Luristan smiths made weapons for both civilizations. The region was later invaded by Assyrians and finally the Iranians settled the area and absorbed the local tribes. Following an accidental find by the local inhabitants in Luristan in 1928 CE, a number of unlawful diggings reveal a number of metal objects made of bronze and iron that showed a high level of craftsmanship. These objects were offered for sale on the art market with fancy names to hide their origin. The subsequent scientific excavations several decades after the initial discovery provided fascinating information about the culture of Luristan. The metalworking art of Luristan spans a time period from the third millennium BC to the Iron Age. The artifacts from Luristan seem to possess many unique and distinctive qualities, and are especially noteworthy for the apparently endless, intricate diversity and detail that they characteristically depict. The bronze artifacts found in or attributed to Luristan can be each be classed under five separate heads: a) arms and armor, including swords, dirks, daggers, axes, mace heads, spearheads, shields, quiver plaques, protective bronze girdles, helmets; b) implements related to horsemanship, including decorative or ornamental objects for horses as well as bits and snaffles; c) items for personal adornment and hygiene, including anklets, bangles, bracelets, finger rings, earrings and tweezers; d) ceremonial and ritual objects, including talismans, idols, pins, anthropomorphic and zoomorphic figurines; and e) utilitarian objects comprising various vessels and tools, including beakers, bowls and jugs. The scope of this article is limited to a discussion of the bronze and iron weapons made in Luristan. The techniques used for making bronze weapons in Luristan included: casting with open molds, casting with close molds, and casting with lost wax process. For metal sheets used for quiver plaques and bronze protective belts, the hammering technique was used. Edged weapons made in Luristan can be classified into: a) daggers, dirks, and swords with tangs; b) daggers, dirks, and swords with flanges; and c) daggers, dirks, and swords with cast-on hilts. Next to bronze, iron was also used for making weapons such as the characteristic weapon from this area, the iron mask sword.

Resumen: El avance que presentamos tiene el propósito de estudiar los antecedentes proto-historiográficos rioplatenses, a través del análisis del “Ensayo de la Historia civil de Buenos Aires, Tucumán y Paraguay”, del Deán Gregorio Funes, y del “Descubrimiento y Población de esta Banda Oriental del Río de la Plata. 1494 - 1818”, del Pbro. Dámaso Antonio Larrañaga. Ambos autores fueron eclesiásticos de acción destacada en el período revolucionario. Se establecerán ciertos ejes comparativos los cuales pretenden abarcar: 1) el periodo colonial, 2) el proceso revolucionario, 3) los límites geográficos por los cuales sobrevuelan los relatos, 4) los modos en que son descriptos los pueblos originarios, 5) los asuntos eclesiásticos y religiosos

No necesitamos justificar la actualidad del problema mente-cuerpo en una parte importante de la filosofía contemporánea. Puede decirse que el nacimiento oficial del asunto se remonta a dos artículos pioneros aparecidos en 1958 y en 1959 escritos por Herbert Feigl el primero y J.J.C. Smart el segundo. Se trata de un asunto planteado en buena medida a partir de los descubrimientos en materia de anatomía y fisiología cerebral y de la relevancia del funcionamiento del cerebro en los actos mentales. Sin ánimo de simplificar excesivamente, puede decirse que las neurociencias se proponen hallar en la complejidad de la organización cerebral la explicación fundamental de la mente misma, e incluso de los actos humanos.

Abstract: During extensive salvage excavations carried out during the years 2004-2008 in a large Early Islamic industrial area at the vicinities of Ramla, in Central Israel, an unparalleled industrial device was unearthed. The star-shaped, soil embedded installation, whose lower part was preserved, consisted of a central pottery jar surrounded by five minor jars, linked by ceramic pipes. Evidence of heat was observed mainly around the central vessel, and metal hollow cones perforated in the tip were found inside the surrounding jars. Although the manufacturing procedures and operation techniques of the installation are not completely clear, it is proposed that the installation is part of an industrial workshop or an alchemy laboratory. Both industry and alchemy were well-developed during the Early Islamic period and very often closely related, to the point that sometimes it is difficult to distinguish between them. The identification proposed is based on comparisons with tools described in literary sources, and somewhat later drawings and etchings. Circumstantial ceramic evidence was found, as well as the proximity of a bathhouse whose guests could have been the consumers of perfumes and unguents seem to reinforce this possibility. Due to the poor state of preservation of the device and the lack of available comparisons, the identification proposed here is tentative, and future research coupled with eventual new discoveries is needed in order to clarify this matter.

Resumen: Muy pocas ciencias avanzaron con la celeridad que muestran las ciencias biológicas. Hoy se abren líneas de investigación que, en poco tiempo, se aplican a los pacientes, mejorando notablemente -en la mayoría de los casos- la calidad de vida. Las terapias con células estaminales son un claro ejemplo de ello. Hoy el tema se ha instalado en la sociedad como parte de la agenda pública. Esta exposición ha llevado a la sociedad a una recepción con un lamentable doble riesgo: perder rigor científico y generar falsas expectativas en muchos pacientes. Dicha polémica también afecta las relaciones entre diversos grupos de investigadores y genera desconfianza en la comunidad científica. Desde la última mitad del siglo XX se ha instalado en las ciencias la necesidad de no escindir el campo de la investigación de las consecuencias éticas que siguen de esa praxis. La causa es evidente: la celeridad de los descubrimientos y su rápida aplicación hacen que, así como los efectos positivos alcanzan a una gran cantidad de personas, en caso de surgir efectos negativos imprevistos, el daño pueda ser igualmente multiplicado. La bioética surge así como un reclamo de los mismos investigadores que decidieron dar un cauce ético a su acción.

Resumen: ¿Cómo se describe y, por lo tanto, cómo se percibe el paisaje natural en ámbitos en permanente tensión y confrontación? ¿Cómo hacer referencia a una realidad geográfica conocida y temida a la vez? Para responder a estas cuestiones recurriré a Los Milagros de Guadalupe conservados en el Archivo del Real Monasterio de Guadalupe (Cáceres, España), milagros que me permitirán profundizar una línea de análisis escasamente desarrollada, como es la del lugar dedicado a los conocimientos geográficos. Estos conocimientos resultan ser muy valiosos, dado que otorgan veracidad al relato guadalupano a la vez que ofrecen caracterizaciones que, además de edificantes desde una perspectiva moral y religiosa, resultan útiles desde un punta de vista práctico al indicar distancias, profundidades de ríos y arroyos, animales a los que temer, etc.
