Estudio mineralógico de los granates de la Unidad de Fuente Piedra (Sierra Nevada, Cordilleras Béticas)

The Fuente Piedra Unit Includes garnet-bearing metape- liks. The mineralogical sIcibdy of garnets reveals a shift to the alniandine end of the Al-Sp-Pyr. series in imreasing con- ditions of metamorphism.

An effort to make sense of antisense transcription in bacteria

Analysis of bacterial transcriptomes have shown the existence of a genome-wide process of overlapping transcription due to the presence of antisense RNAs, as well as mRNAs that overlapped in their entire length or in some portion of the 5′- and 3′-UTR regions. The biological advantages of such overlapping transcription are unclear but may play important regulatory roles at the level of transcription, RNA stability and translation. In a recent report, the human pathogen Staphylococcus aureus is observed to generate genome-wide overlapping transcription in the same bacterial cells leading to a collection of short RNA fragments generated by the endoribonuclease III, RNase III. This processing appears most prominently in Gram-positive bacteria. The implications of both the use of pervasive overlapping transcription and the processing of these double stranded templates into short RNAs are explored and the consequences discussed. © 2012 Landes Bioscience.This research was supported by grants ERA-NET Pathogenomics (PIM2010EPA-00606), BIO2008-05284-C02, BIO2011- 30503-C02 and BFU2011-23222 from Spanish Ministry of Economy and Competitiveness.A.T.-A. is recipient of “Ramon y Cajal” contracts from the Spanish Ministry of Science and Innovation.

Los granates del tramo del núcleo de la Sierra de los Santos (Córdoba)

The Sierra de los Santos (Sierra Morena, prov. of Córdoba) consists of precambric and paleozoic materials, essentially chloritic schists, limestones and small outcrops of acid and basic igneous rocks. The garnets studied in this work are the only relict minerals from the first metamorphism process developped in this área. X-ray, optical and chemical data of these garnets are reported. They correspond to the piralspite series; finally, metamorphism conditions having given birth to the garnets are discussed

Agriculture and water resources: UNFCCC influence on Peruvian adaptation regulations to increase resilience against climate change

Agriculture and water resource are highly threatened due to climate change, increasing the probability of backsliding on almost every aspect of sustainable development worldwide. For instance, water resource distribution throughout the Peruvian territory is not homogeneous. Hydrometeorological phenomena also threaten it, so it is crucial for the agriculture sector and water management to increase resilience against climate change. The study aims to understand the Peruvian conduct under the United Nations Framework Convention on Climate Change (UNFCCC) regime. Its influence in the Peruvian adaptation regulation and public institutions over the years and the interaction with the latest commitment to the UNFCCC related to climate change agriculture - water resources. The methodology used for the study was qualitative, delivered throughout a documentary analysis, and narrative design among scientific papers, UNFCCC documentation, and Peruvian regulation to weave the experience occurred and the sequences of the events to set up a general narrative. The results show that Peru has active participation in the UNFCCC, particularly under a neoliberalism approach. The convention pushed institutional and regulatory development of the Peruvian Government constantly. Also, after the Paris Agreement, one of the most important influences was the implementation of Law N° 30754 on climate change, which articulates all the regulations related to it, providing a national, more substantial legally-binding commitment. Finally, it is important for Peru to analyze the achievement of current adaptation actions and keep studying the impacts of climate change at a local level to develop a bottom-up approach for an effective policy formulation-implementation
