NEW EVIDENCES ABOUT THE MIOCENIC MAGMATISM IN THE VETASCALIFORNIAMINING DISTRICT (SANTANDER MASSIF, EASTERNCORDILLERA, COLOMBIA)

En el distrito Minero de Vetas-California (DMVC) afloran rocas ígneas tanto de textura porfirítica-afanítica, como de textura porfirítica-fanerítica, relacionadas con el evento magmático más reciente conocido hasta el momento para el Macizo de Santander, de edad Mioceno. Estas rocas, al parecer se confinan hacia las zonas de influencia de fallas NNW (similares en su dirección a la Falla Bucaramanga-Santa Marta) y un sistema de fallas NE. Las rocas con textura porfirítica-fanerítica y de composiciones entre cuarzo monzodioritas y granodioritas, por ahora solo han sido observadas al Éste del área de estudio, mientras que las rocas de textura porfirítica afanítica, de composiciones entre andesitas porfiríticas y riodacitas porfiríticas, son más frecuentes al Oeste. Dos tipos de rocas datadas en el presente estudio; una de variedad andesita porfirítica, localizada en el lado Oeste del área de estudio y otra de una granodiorita de textura porfirítica-fanerítica, localizada al Éste del área; arrojaron edades de 10.1±0.2 y 10.9±0.2 Ma, respectivamente (utilizando el método U-Pb en circones, mediante la técnicaLA-MC-ICPMS: laser ablation multicollector inductively coupled plasma mass spectrometry). En este sentido, y apoyados en las aún limitadas edades conocidas, se infiere que este sector del Macizo de Santander fue afectado por un pulso ígneo de por lo menos 2.5 Ma de duración. La presencia de rocas ígneas de edad Mioceno afectadas por procesos de alteración hidrotermal y con estilos de mineralización epitermal y porfirítica, y la falta de evidencias de rocas ígneas más jóvenes que 8.4 Ma, permiten sugerir que en algún(os) momento(s) de la evolución del magmatismo Miocenico, pudieron tener lugar procesos magmático-hidrotermales asociados a eventos mineralizantes en el DMVC. Palabras clave: Distrito Minero Vetas-California (DMVC), Mioceno, Fallas, Edades U-Pb, Macizo de Santander.      In The Vetas-California Mining District (DMVC), igneous rocks with porphyritic-aphanitic and porphyriticphaneritic textures crop out, which are related to the Miocene and most recent magmatic event known for the Santander Massif. The emplacement of these rocks is apparently controlled by the intersections of NNW faults(similar in direction to the Bucaramanga-Santa Marta fault) and the NE fault systems. Porphyritic-phaneriticquartz’ monzodiorites and granodiorite rocks are confined to the eastern part of the studied area; mean while the porphyritic-aphanitic andesite and rhyodacitic rocks are confined to the western part. The two types ofigneous rocks dated in this study; a porphyritic andesite variety (located to the western part of the studied area)and a granodiorite with prophyritic-phaneritic texture (located to the eastern part); yielded ages of 10.1 ± 0.2and 10.9 ± 0.2 Ma, respectively (U-Pb method on zircons, using the LA-MC-ICPMS technique: laser ablation inductively coupled plasma multicollector mass spectrometry). These ages, together with previously published data, indicate that magmatic pulse lasted up to 2.5 Ma. The presence of Miocene igneous rocks affected by hydrothermal alteration and with epithermal and porphyry style mineralization, and the absence of igneous rocks younger than 8.4 m.y. (at least currently not known), allow to propose that during some time(s) of the Miocenic magmatic pulse,could take place magmatic-hydrothermal processes related to mineralizing events inthe DMVC.

Evolutionary biology and computational grids

The global high performance computing community has seen two overarching changes in the past five years. One of these changes was the consolidation toward SMP clusters as the predominant HPC system architecture. The other change was the emergence of computing grids as an important architecture in high performance computing. Several major national and international projects are now underway to develop grid technologies. Computational grids will increase the resources available to the most advanced computational scientists and encourage the use of advanced techniques by researchers who have not traditionally employed such technologies. In the latter camp are bioinformaticists in general and evolutionary biologists in particular, although this situation is changing rapidly.This work was greatly facilitated by IBM Shared University Research grants to Indiana University in 1998 and 1999

Cumulative dietary risk characterisation of pesticides that have chronic effects on the thyroid

A retrospective chronic cumulative risk assessment of dietary exposure to pesticide residues, supported by an uncertainty analysis based on expert knowledge elicitation, was conducted for two effects on the thyroid, hypothyroidism and parafollicular cell (C‐cell) hypertrophy, hyperplasia and neoplasia. The pesticides considered in this assessment were identified and characterised in the scientific report on the establishment of cumulative assessment groups of pesticides for their effects on the thyroid. Cumulative exposure assessments were conducted through probabilistic modelling by EFSA and the Dutch National Institute for Public Health and the Environment (RIVM) using two different software tools and reported separately. These exposure assessments used monitoring data collected by Member States under their official pesticide monitoring programmes in 2014, 2015 and 2016 and individual consumption data from 10 populations of consumers from different countries and different age groups. This report completes the characterisation of cumulative risk, taking account of the available data and the uncertainties involved. For each of the 10 populations, it is concluded with varying degrees of certainty that cumulative exposure to pesticides that have the chronic effects on the thyroid mentioned above does not exceed the threshold for regulatory consideration established by risk managers

A translational framework for public health research

<p><b>Background</b></p> <p>The paradigm of translational medicine that underpins frameworks such as the Cooksey report on the funding of health research does not adequately reflect the complex reality of the public health environment. We therefore outline a translational framework for public health research.</p> <p><b>Discussion</b></p> <p>Our framework redefines the objective of translation from that of institutionalising effective interventions to that of improving population health by influencing both individual and collective determinants of health. It incorporates epidemiological perspectives with those of the social sciences, recognising that many types of research may contribute to the shaping of policy, practice and future research. It also identifies a pivotal role for evidence synthesis and the importance of non-linear and intersectoral interfaces with the public realm.</p> <p><b>Summary</b></p> <p>We propose a research agenda to advance the field and argue that resources for 'applied' or 'translational' public health research should be deployed across the framework, not reserved for 'dissemination' or 'implementation'.</p&gt
