The ‘Urbanforest’ and ‘Green space’ Classification Model in the Spatial Arrangement of Registro-SP, Brazil

The necessity of handling green areas relating to urban settings has become one of the vital environmental challenges in view of several accumulated environmental problems in the last few decades. In United States and Canada, many investments are being made for new techniques and instruments that are needed in environmental planning involving urban forest researches both in the local and national scale. However, there are few reports on urban forest classification connecting spatial characteristics, physical structures involving pattern and process. With the objective to classify urban green areas for integrated approach, this research have focused on urban pattern for an effective understanding of urban forest concept, green areas and urban vegetation types. The urban morphology in consistency with the urban forest Focus Chat (FC) recently designed has been applied to characterize spatial categories of urban vegetation involved in the urban arrangement of Registro-SP. Method has integrated zones, patterns and processes for technical analyses to contemplate the urban dynamics, occupation and land use. Categories of urban forest and vegetation types were derived for the urban planning and system management. The resulting pattern can be technically monitored in the use of suitable GIS (Geographical Information System) software for physical and environmental records.

Nuevas perspectivas en la gestión de las administraciones públicas: una visión comparada de la contratación pública electrónica.

the incorporation of technology to public activity brings us not only a «modernization», it is creating deep transformations in the management model, opening news opportunities to stakeholders’ participation and to the control. In this paper we analyze, in a comparative way, two of the current models of electronic public procurement, which come from political-territorial different areas with different development too: Spain and brazil. We show the evolution in both cases, the problems and difficulties they have to deal with, the solutions given, and the conditions they are living nowadays.La progresiva incorporación de medios electrónicos en la actividad pública no solo supone una «modernización », sino que está implicando una profunda transformación del modelo de gestión, abriendo nuevas posibilidades a la participación de los actores y al control. en el presente trabajo se analiza, de un modo comparado, dos de los modelos existentes en materia de contratación pública electrónica, pertenecientes a ámbitos político-territoriales diferenciados y con trayectorias también diferentes, como son el español y el brasileño. Se muestran los procesos evolutivos seguidos en ambos casos, los problemas y dificultades a los que se enfrentan, las soluciones planteadas y la situación en la que se encuentran en estos momentos

Terrestrial Megafauna Response to Drone Noise Levels in Ex Situ Areas

Drone use has significantly grown in recent years, and there is a knowledge gap on how the noise produced by these systems may affect animals. We investigated how 18 species of megafauna reacted to drone sound pressure levels at different frequencies. The sound pressure level on the low frequency generated by the drone did not change the studied species’ behavior, except for the Asian elephant. All other studied species showed higher noise sensitivity at medium and high frequencies. The Asian elephant was the most sensitive species to drone noise, mainly at low frequencies. Felines supported the highest sound pressure level before showing behavioral reactions. Our results suggest that drone sound pressure levels in different frequencies cause behavioral changes that differ among species, which is relevant to assessing drone disturbances in ex situ environments. The findings presented here can help to reduce drone impact for target species and serve as an experimental study for future drone use guidelines.M.M.P. contract is funded by the European Union “NextGenerationEU” Programa María Zambrano, Ministerio de Universidades, Spain.

Estudios toxicologicos como herramienta para evaluar el desempeno de un reactor anaerobio de biomasa inmovilizada

Los efluentes de la Industria de Papel y Celulosa son usualmente tóxicos y mutagénicos. Esa característica se deriva principalmente por la presencia de compuestos xenobióticos formados durante el proceso. Los parámetros globales para el análisis de la calidad del agua como: demanda química de oxigeno, carbón orgánico total, entre otros, no permiten identificar si el potencial toxicológico es remediado después de los tratamientos. El objetivo de este trabajo fue evaluar el desempeño de un reactor anaerobio horizontal de biomasa inmovilizada (RAHBI) tratando un efluente real de blanqueamiento de celulosa Kraft, por medio de ensayos de toxicidad (Daphnia similis - Ceriodaphnia silvestrii ), mutagenicidad y citotoxicidad (Allium cepa L. ). Los resultados mostraron alta sensibilidad de todos los organismos estudiados y buena capacidad del reactor anaerobio para remover compuestos que ejercen efectos tóxicos y mutagénicos. Los bioensayos estudiados representan una alternativa interesante para el análisis de la calidad del agua y para la evaluación del desempeño de tratamientos

Labeling of Monilinia fructicola with GFP and Its Validation for Studies on Host-Pathogen Interactions in Stone and Pome Fruit

To compare in vivo the infection process of Monilinia fructicola on nectarines and apples using confocal microscopy it is necessary to transform a pathogenic strain with a construct expressing a fluorescent chromophore such as GFP. Thus, germinated conidia of the pathogen were transformed with Agrobacterium tumefaciens carrying the plasmid pPK2-hphgfp that allowed the expression of a fluorescent Hph-GFP chimera. The transformants were selected according to their resistance to hygromycin B, provided by the constitutive expression of the hph-gfp gene driven by the glyceraldehyde 3P dehydrogenase promoter of Aspergillus nidulans. The presence of T-DNA construct in the genomic DNA was confirmed by PCR using a range of specific primers. Subsequent PCR-mediated analyses proved integration of the transgene at a different genomic location in each transformant and the existence of structural reorganizations at these insertion points. The expression of Hph-GFP in three independent M. fructicola transformants was monitored by immunodetection and epifluorescence and confocal microscopy. The Atd9-M. fructicola transformant displayed no morphological defects and showed growth and pathogenic characteristics similar to the wild type. Microscopy analysis of the Atd9 transformant evidenced that nectarine infection by M. fructicola was at least three times faster than on applesinfo:eu-repo/semantics/publishedVersio

Optical/NIR stellar absorption and emission-line indices from luminous infrared galaxies

We analyze a set of optical-to-near-infrared long-slit nuclear spectra of 16 infrared-luminous spiral galaxies. All of the studied sources present H$_2$ emission, which reflects the star-forming nature of our sample, and they clearly display H I emission lines in the optical. Their continua contain many strong stellar absorption lines, with the most common features due to Ca I, Ca II, Fe I, Na I, Mg I, in addition to prominent absorption bands of TiO, VO, ZrO, CN and CO. We report a homogeneous set of equivalent width (EW) measurements for 45 indices, from optical to NIR species for the 16 star-forming galaxies as well as for 19 early type galaxies where we collected the data from the literature. This selected set of emission and absorption-feature measurements can be used to test predictions of the forthcoming generations of stellar population models. We find correlations among the different absorption features and propose here correlations between optical and NIR indices, as well as among different NIR indices, and compare them with model predictions. While for the optical absorption features the models consistently agree with the observations,the NIR indices are much harder to interpret. For early-type spirals the measurements agree roughly with the models, while for star-forming objects they fail to predict the strengths of these indices.Comment: accepted for publication in MNRA
