Modelo de base tecnológica para la responsabilidad social universitaria mediado con apropiación social del conocimiento

Objetivo General Analizar los componentes de RSE dinámicos vinculados con la ASC, por medio de prácticas universitarias en interrelación con ambientes de la pentahélice (industial-productivo, gubernamental, social, medio ambiental y academico) y la medición de los niveles de los niveles de intercambio de información, negociación y transferencia de conocimiento de la responsabilidad social en ambientes universitarios, con el fin de proponer un modelo de base tecnológica para la sistematización de la RSU

Biomasa y stock de carbono en la Reserva de Campo Alegre, la caldera, provincia de Salta

En un bosque secundario de la Reserva Privada Campo Alegre, provincia de Salta, en zona de transición entre dos regiones naturales: Yungas y Chaco, se estimó la biomasa leñosa aérea, subterránea y stock de carbono. Se zonificó la Reserva en bosque de galería, bosque de filo, zona incendiada y zona no incendiada, y se realizó un muestreo al azar estratificado (n: 36). Interesó comparar el stock de carbono de los distintos sitios y su contribución al conjunto de la Reserva. Se emplearon distintos modelos alométricos construidos en ecosistemas similares al área de estudio. Se realizó un ANOVA y test de Tukey; encontrándose diferencias significativas en algunos sitios con respecto a otros. El stock total de carbono de la biomasa (aérea y subterránea) de la Reserva fue de 63,25 tn C/ha. Esta información contribuirá al determinar el potencial de mitigación de estos bosques frente al Cambio Climático Global (CCG).Fil: Ontiveros, Silvina Noemí.

Microbial Sampling of Major Bodies of Water in Rochester, NY

Public health concerns from wastewater treatment and agricultural runoff are an issue locally in Rochester, NewYork. In fact, many closings of Ontario Beach have been attributed to pollution or the threat of microbial contamination. Antibiotic resistance is a major issue that has become more prevalent in society, antibiotic resistant human pathogenic bacteria can overcome normal types of medicinal therapy, which cannot only lead to increased mortality but also increases in illness and cost of care. Additionally, antibiotic resistant plant pathogens can impact agriculture. In this study, bacterial species from the Lake Ontario embayment collected over the past three years were analyzed. Bacteria that were known to be human or plant pathogens were selected to evaluate for resistance to commonly used antibiotics using the Kirby Bauer disk diffusion assay. A few species exhibited resistance, preliminary results will be shown

Building a Freshwater Bacterial Flora Database for Remote Sensing Applications

The identification and classification of microbial flora in bodies of fresh water has the potential of enhancing our understanding of this ecosystem and improving water management and bioremediation. This effort may be facilitated by the use of remote sensing technologies. For the last 3 years our undergraduate students have collected water samples in the Lake Ontario Rochester Embayment and Irondequoit Bay with the goal of constructing a database of bacterial species and water parameters (e.g. organic matter and chlorophyl content). Such a database is necessary to establish potential correlations between the presence of certain bacterial species and water parameters that can be measured using satellite imagery collected by the Landsat 8 OLI and TIRS sensors. In the past we reported initial efforts at mapping the distribution of bacterial species using 16S rRNA. Here we present our results for the summer of 2015 and present a compounded analysis of 3 consecutive summers. Of approximately 450 bacterial isolates, we have cultured and identified more than 40 different species spanning over 20 genera. Several fish and human pathogens were identified, and antibiotic-resistance profiles determined. Year to year variation of the flora’s composition at individual locations has emerged as the main challenge in establishing reproducible patterns that may be linked to satellite measurements

Multi-Year Analysis of Microbial Populations in the Rochester-Lake Ontario Embayment

The composition of freshwater bacterial populations is affected by a wide variety of factors. Temperature, acidity, organic matter, and environmental pollutants like industrial chemicals and antibiotics are a few examples. The impact that bodies of freshwater have on human activity and the wider ecosystem warrants the systematic identification of microbial flora, and in particular of species known to be pathogenic in plants and animals. In order to achieve the long term goal of using satellite imagery to predict the occurrence of specific bacterial species, our team is in the process of creating a multi-location, multi-year microbial flora database for the Rochester Lake Ontario embayment and nearby bodies of water. Our collaborators at the Rochester Institute of Technology have provided us with water samples collected at these locations during the summers of 2013 and 2014. In this work we present and analyze data from said samples. Using 16S ribosomal DNA data we characterize bacterial populations, determine their geographical distribution, establish genera prevalence and discuss the presence of and investigate antibiotic resistance in several pathogenic species. The scope of our long term project and the summer of 2015- sample collection are also considered

HerschelHerschel/PACS OH Spectroscopy of Seyfert, LINER, and Starburst Galaxies

We investigated the 65$\mu$m, 71$\mu$m, 79$\mu$m, 84$\mu$m, 119$\mu$m, and 163$\mu$m OH doublets of 178 local (0 < $z$ < 0.35) galaxies. They were observed using the $Herschel$/PACS spectrometer, including Seyfert galaxies, LINERs, and star-forming galaxies. We observe these doublets exclusively in absorption (OH71), primarily in absorption (OH65, OH84), mostly in emission (OH79), only in emission (OH163) and an approximately even mix of the both (OH119). In 19 galaxies we find P-Cygni or reverse P-Cygni line profiles in the OH doublets. We use several galaxy observables to probe spectral classification, brightness of a central AGN/starburst component, and radiation field strength. We find that OH79, OH119, and OH163 are more likely to display strong emission for bright, unobscured AGN. For less luminous, obscured AGN and non-active galaxies, we find populations of strong absorption (OH119), weaker emission (OH163), and a mix of weak emission and weak absorption (OH79). For OH65, OH71 and OH84, we do not find significant correlations with the observables listed above. We do find relationships between OH79 and OH119 with both the 9.7$\mu$m silicate feature and Balmer decrement dust extinction tracers in which more dust leads to weaker emission / stronger absorption. The origin of emission for the observed OH doublets, whether from collisional excitation, or from radiative pumping by infrared photons, is discussed.Comment: 29 pages, 10 figures, 5 machine readable tables and 6 supplemental figures available upon reques

Integration of Mouse Ovary Morphogenesis With Developmental Dynamics of the Oviduct, Ovarian Ligaments, and Rete Ovarii

Morphogenetic events during the development of the fetal ovary are crucial to the establishment of female fertility. However, the effects of structural rearrangements of the ovary and surrounding reproductive tissues on ovary morphogenesis remain largely uncharacterized. Using tissue clearing and lightsheet microscopy, we found that ovary folding correlated with regionalization into cortex and medulla. Relocation of the oviduct to the ventral aspect of the ovary led to ovary encapsulation, and mutual attachment of the ovary and oviduct to the cranial suspensory ligament likely triggered ovary folding. During this process, the rete ovarii (RO) elaborated into a convoluted tubular structure extending from the ovary into the ovarian capsule. Using genetic mouse models in which the oviduct and RO are perturbed, we found the oviduct is required for ovary encapsulation. This study reveals novel relationships among the ovary and surrounding tissues and paves the way for functional investigation of the relationship between architecture and differentiation of the mammalian ovary
