Equality with Democracy: The Batilist Project in Uruguay as an Alternative to the Cuban Model

During the first three decades of the 2 0th century, Batllismo (a majority political movement sponsored by the Partido Colorado, headed by Jose Batlle y Ord6fiez) carried out an innovative project that laid the groundwork for a full Welfare State in Uruguay. A pioneer in the hemisphere and even in the world, Batllismo created the conditions for a society with a profound sense of equality and solidarity, combining an omnipresent State with an unlimited respect for institutions and political and individual liberty. The analysis of this process is relevant for contemporary Latin America and particularly for Cuba, where the search for equality and justice has been subordinated to authoritarian processes that put aside the respect for liberty and democracy. The old spirit of Batllismo may be useful to think about a future transition in the Cuban case.https://digitalcommons.fiu.edu/cri_events/1401/thumbnail.jp

El sitio de los dólmenes de Antequera en la obra de Georg y Vera Leisner: una revisión

The Antequera dolmens site (Malaga, Spain), included in the UNESCO World Heritage List since July 2016, has a research history of almost 200 years that goes back to the work of Rafael Mitjana y Ardison in the 1840s. After the discovery of the Viera dolmen and El Romeral tholos, in 1903 and 1904 respectively, the research of the great megalithic site received a renewed impulse. Published in 1943, the first volume of the corpus of Iberian megalithic monuments by Georg and Vera Leisner (Die Megalithgräber der Iberischen Halbinsel, Erster Teil: Der Süden) was to become the most detailed study of the Antequera site during the second half of the 20th century, despite the fact that being published in German limited its penetration among the Spanish scholarship. Here, we review the importance of the work of the Leisners to understand the Antequera megaliths in light of the results of the research that has been undertaken in the last 15 years. Many of the issues raised by the German couple continue to be fully pertinent within the context of today’s research on these monuments. In addition, to facilitate future access to their work, this paper is accompanied by full translations into English and Spanish of the Leisners’s text on the Antequera megaliths.El sitio de los dólmenes de Antequera (Málaga, España), inscrito en la Lista del Patrimonio Mundial de UNESCO desde julio de 2016, cuenta con una historia de investigación de casi 200 años que se remonta al trabajo de Rafael Mitjana y Ardison en la década de 1840.

Publicado en 1943, el primer volumen del gran corpus de monumentos megalíticos ibéricos de Georg y Vera Leisner (Die Megalithgräber der Iberischen Halbinsel. Erster Teil: Der Süden) habría de convertirse en el estudio más detallado del sitio antequerano durante toda la segunda mitad del siglo XX, a pesar de que el hecho de estar publicado en alemán lo hacía de difícil acceso para muchos estudiosos españoles. En este artículo revisamos la importancia de la obra de los Leisners para entender los megalitos antequeranos a la luz de los resultados de las investigaciones que se vienen desarrollando desde hace 15 años. Son muchas las cuestiones planteadas en la obra del matrimonio alemán que siguen teniendo plena vigencia en la investigación actual de estos monumentos.

CORN (\u3cem\u3eZea mays\u3c/em\u3e L.) YIELD RESPONSE TO DEFOLIATION AT DIFFERENT ROW WIDTHS

Corn (Zea mays L.) defoliation experiments have been conducted for more than 120 years. However, there is limited data on the effect of row width on defoliation in modern hybrids. A two-year experiment was conducted in Lexington, Kentucky with two hybrids (113 relative maturity (RM) and 120 RM), two row widths (38 and 76 cm) and a combination of defoliation timings and severities: 0% defoliation (control), V7-100%, V14-50%, V14-100%, R2-50% and R2-100%. No yield difference among hybrids was observed in 2012. Yields were 26% greater in 38-cm rows than 76-cm rows in 2012. For 2013, corn yield for 38-cm was 10% greater, but hybrid, row width and defoliation interacted. Lowest yields were caused by V14-100% followed by R2-100%. Defoliations of V14-50% and R2-50% reduced yields in some cases. Complete defoliations at V7 did not reduce yields in most comparisons. Light interception below 80% during the critical period was enough to attain maximum yields in defoliated plants. Kernel number and kernel weight were most reduced by V14-100% and R2-100% defoliations, respectively. There is a potential for narrow rows to reduce grain yield losses after a defoliation event, when compared with wide rows

Prospects of Plant-Based Systems as an Eco-Technological Approach for Heavy Metals Removal from Polluted-Waters

Contamination of natural waters by the release of aqueous effluents containing organic and inorganic poisoning substances, mostly from agro-industrial origin, has been hard increased since the beginning of the 21st century. In the last decades, environmental contamination with heavy metals has turned to a worldwide problem due to the fast growing of industrialization and urbanization. Metals are major pollutants of fresh-water reservoirs because of their non-biodegradability and highpersistence in nature. In addition, some metals are highly toxic even at very low concentrations [1]. Heavy metals are not only a serious threat to the environment but also to all living beings, including humans, since all metallic ions are inert to chemical and biological degradation and can be transferred through the trophic chain [2].Fil: Perez, Leonardo Martin.

Constructed Wetlands for Marine Aquaculture Wastewater Treatment: A New Challenge

Aquaculture is the fastest growing food production sector worldwide. Global demand for seafood continues to grow, and landbased aquaculture is expected to grow in order to meet the increasing market demand. In this context, marine aquaculture production systems are moving towards land-based farming. However, due to the large volumes of wastewater with high salinity and other fish-metabolism derived pollutants (e.g., nitrogen compounds), it remains a challenge for treatment of effluents from land-based marine aquaculture. In this scenario, development of environmental-friendly and efficient aquaculture effluent treatment system is crucial for sustainable intensification of aquaculture. Owing to low capital, operating costs, and low energy consumption, constructed wetlands (CWs) are becoming a promising technique to treat aquaculture effluents before discharge.Fil: Perez, Leonardo Martin.

La vida y el sol: La inevitable tendencia al desorden y la (aparente) paradoja de la vida

Los seres vivos toman materia simple de su entorno y la organizan construyendo sistemas altamente complejos, lo que parece contradecir la natural tendencia al desorden del universo conocida como entropía. ¿Cómo logran los seres vivos construirse y perpetuarse contra esta tendencia a la degradación? La clave está en su habilidad para utilizar la energía proveniente del Sol para imponer orden a la materia que los constituye.Fil: Leonardo González Galli.
