La Edad del Bronce en las tierras meridionales valencianas. Panorama y perspectivas
Se analiza la Edad del Bronce en la provincia de Alicante a partir de la documentaciĂłn generada en más de un siglo de investigaciones. Se identifican los “territorios” del Bronce Argárico y Bronce Valenciano, cuestionándose la distribuciĂłn y caracterizaciĂłn de este Ăşltimo. Se presta una especial atenciĂłn al Bronce TardĂo a partir de las excavaciones en el Cabezo Redondo y en otros yacimientos de la cuenca del rĂo VinalopĂł.In this paper, the Bronze Age in the province of Alicante (Valencia region, Eastern Spain) is analyzed, taking into account the archaeological record generated in more than one century of research. The territorial demarcation of the Argaric Bronze Age and Valencian Bronze Age are identified, being questioned the distribution and characterization of this last one. I focus a special attention to the Late Bronze from the excavations in El Cabezo Redondo and in other sites of the basin of the river VinalopĂł
Art rupestre a l’arc mediterrani de la penĂnsula Ibèrica. Del Cogul a Kyoto
Roca dels Moros in El Cogul is the first set of prehistoric paintings documented in Catalonia, and since its discovery in 1908 it has been a referent in prehistoric art on the Iberian Peninsula. Its existence garnered international attention on par with the bison of Altamira. The history of Roca dels Moros in El Cogul is the history of prehistoric rock art on the eastern side of the Iberian Peninsula. Based on this site, this article is a synthesis of the results of a study on the post-Palaeolithic rock art of the Mediterranean basin on the Iberian Peninsula for over 100 years, along with a discussion of the public administrations’ efforts to further the conservation and protection of this kind of archaeological site. These efforts have earned the rock art of the Mediterranean basin on the Iberian Peninsula a place on UNESCO’s list of World Heritage Sites.La Roca dels Moros del Cogul Ă©s el primer conjunt de pintures prehistòriques documentat a Catalunya i va ser des del moment del seu descobriment, l’any 1908, un referent de l’art prehistòric peninsular; la seva existència adquirĂ un ressò internacional equiparable a l’assolit pels bisons d’Altamira. La història de la Roca dels Moros del Cogul Ă©s la història de l’art rupestre prehistòric del vessant oriental de la penĂnsula Ibèrica. A partir d’aquest conjunt, es fa una sĂntesi dels resultats de la investigaciĂł sobre l’art rupestre postpaleolĂtic a l’arc mediterrani de la penĂnsula Ibèrica durant mĂ©s de cent anys, sense oblidar els esforços realitzats des de les administracions per avançar en la conservaciĂł i protecciĂł d’aquest tipus de jaciments arqueològics, cosa que va fer possible la inclusiĂł de l’art rupestre de l’arc mediterrani de la penĂnsula Ibèrica a la llista del Patrimoni Mundial de la UNESCO.Part of this study was conducted under the research project 2009-13723 HAR “VIII-VI millennia cal BC Rock Art, bending and cultural change between the basins of the rivers JĂşcar and Segura”, funded by the DGICTYT of the Ministries of Science and Technology and Economy
El final del arte rupestre prehistórico en el arco mediterráneo peninsular
Se cuestiona el final del arte prehistĂłrico en el arco mediterráneo de la penĂnsula IbĂ©rica a partir de análisis de algunas imágenes tradicionalmente adscritas a los artes Levantino y Esquemático. TambiĂ©n se presta una especial atenciĂłn a los grabados rupestres, algunos de los cuales podrĂan situarse en la Edad del Bronce y Edad del Hierro.In this paper we discuss the end of prehistoric art in the Mediterranean Basin of the Iberian Peninsula from the analysis of some images traditionally ascribed to the Levantine and Schematic art. Furthermore it pays special attention to the rock engravings, some of which could be dated during the Bronze Age and the Iron Age.Este trabajo se ha realizado en el marco del proyecto de investigaciĂłn HAR 2012-37710 “III y II milenios cal. BC: poblamiento, ritualidad y cambio social entre las cuencas de los rĂos JĂşcar y Segura”, financiado por el Ministerio de EconomĂa y Competitividad
Yield Components in a Signal Grass-Clitoria Mixture Grazed at Different Herbage Allowance
A Signal grass-Clitoria mixture provides good quality forage in the dry tropic of southern Mexico. However, its response in leaf and stem yields to grazing at different daily herbage allowances is not well documented. The objective of this study was to determine available and residual leaf and stem yields in a Signal grass (Brachiaria decumbens)-Clitoria (Clitoria ternatea) mixture grazed at different daily herbage allowance
40th anniversary of the World Heritage Convention. La Sarga (Alcoi, Alicante, Spain) as paradigm
Con ocasiĂłn del 40 aniversario de la ConvenciĂłn sobre la ProtecciĂłn del Patrimonio Mundial se analizan los trabajos de investigaciĂłn, protecciĂłn y difusiĂłn de las pinturas prehistĂłricas de La Sarga (Alcoi, Alicante). En 1998 se incluyĂł, junto a otros conjuntos con arte rupestre del arco mediterráneo de la penĂnsula IbĂ©rica, en la lista de Patrimonio Mundial de la UNESCO.Amb ocasiĂł del 40Ă© aniversari de la ConvenciĂł sobre la ProtecciĂł del Patrimoni Mundial s’analitzen els treballs d’investigaciĂł, protecciĂł i difusiĂł de les pintures prehistòriques de la Sarga (Alcoi, Alacant). En 1998 es va incloure, juntament amb altres conjunts amb art rupestre de l’arc mediterrani de la penĂnsula Ibèrica, en la llista de Patrimoni Mundial de la UNESCO.On the occasion of the 40th anniversary of The World Heritage Convention, we analyze the work of research, protection and diffusion of the prehistoric Rock Art of La Sarga (Alcoi, Alicante, Spain). In 1998 La Sarga was included in the UNESCO World Heritage list, along with other Rock Art sites of the Mediterranean area of the Iberian Peninsula.Este trabajo se ha realizado en el marco del proyecto de investigaciĂłn HAR 2009-2012 “VIII-VI milenio cal.

Forage Yield and Quality of Signal Grass-Clitoria Mixture Grazed at Different Frequencies
A Signal grass-Clitoria mixture provides good quality forage in the dry tropic of southern Mexico. Grazing frequency is a management tool that determines yield, botanical components and quality of pastures. The objective of this study was to determine forage yield, quality and botanical components in a Signal grass (Brachiaria decumbens)-Clitoria (Clitoria ternatea) mixture when grazed at different frequencies
Carrier-wave Rabi flopping signatures in high-order harmonic generation for alkali atoms
We present the first theoretical investigation of carrier-wave Rabi flopping
in real atoms by employing numerical simulations of high-order harmonic
generation (HHG) in alkali species. Given the short HHG cutoff, related to the
low saturation intensity, we concentrate on the features of the third harmonic
of sodium (Na) and potassium (K) atoms. For pulse areas of 2 and Na atoms,
a characteristic unique peak appears, which, after analyzing the ground state
population, we correlate with the conventional Rabi flopping. On the other
hand, for larger pulse areas, carrier-wave Rabi flopping occurs, and is
associated with a more complex structure in the third harmonic. These new
characteristics observed in K atoms indicate the breakdown of the area theorem,
as was already demonstrated under similar circumstances in narrow band gap
semiconductors
