Estudio comparativo sobre el efecto de las políticas públicas urbanas en los barrios patrimoniales de dos ciudades Argentinas

This is a comparative study of two heritage neighborhoods with high market values, adjacent to the central areas in two intermediate Argentinean cities. Both have large vacant buildings, where individual actors and land use regulations have determined different scenarios. In Córdoba, Maipú keeps the suburbia model, which causes informal micro interventions in order to increase its density. In Rosario, Pichincha induces building rehabilitation, completion and renovation processes through a special development plan. At first, the historical development of each section is described, emphasizing the similarities and differences found (built heritage, connections to the city, functional role). Afterwards, the current land use regulations (regarding protection policies of heritage and urban renewal) are exposed. Subsequently, features are described in the residential market. Finally, urban processes product both of the socio economic conditions and land use regulations are analyzed.El presente es un estudio comparativo de dos barrios patrimoniales con alto valor inmobiliario, aledaños a las áreas centrales en dos ciudades intermedias de Argentina. Ambos cuentan con construcciones de grandes dimensiones vacantes de uso donde los actores individuales y el Estado determinaron escenarios diferentes. En Córdoba, Maipú continúa con la antigua normativa de zonas suburbanas, lo que provoca intervenciones informales de densificación de media densidad. En Rosario, Pichincha induce procesos de rehabilitación, completamiento y renovación edilicia a través de un plan especial. En primer lugar, se describe el desarrollo histórico de cada barrio, haciendo énfasis en las similitudes y diferencias encontradas (patrimonio construido, conexiones con la ciudad, rol funcional). Luego, se exponen las normativas vigentes en relación a las políticas de protección del patrimonio y renovación urbana. Posteriormente se enuncia las características del mercado residencial. Por último, analiza los procesos urbanos producto de las condiciones socioeconómicas y normativas planteadas

Using balance training to improve the performance of youth basketball players

The aim of this study was to evaluate the effectiveness of 12 weeks of balance training to improve the balance and vertical jump abilities of young basketball players. Twenty-three players from two teams in the Under Fifteen Basketball Excellence category participated in the study. Participants were divided into two training groups: balance training (BAL, n = 11) and isotonic training (ISO, n = 12). Both groups were tested for balance and vertical jumps at the beginning of the competitive season and at the end of 12 weeks of specific training programme. All of the tests were performed in sustained bipodalic and mono- podalic (both right and left) positions. The results showed that players who participated in balance training for 12 weeks, compared to players who trained with isotonic machines, exhibited a significantly increase in balance (bipodalic 28.3 %; right 41.4 %; left 45.8 %; p \ 0.01) and muscular power (bipodalic 8.1 %; right 13.5 %; left 12.5 %; p \ 0.01) as measured through a vertical jump. In conclusion, balance training using unstable boards was an effective training method for improving balance and the vertical jump, which is a basketball-specific action that frequently occurs in this sport

Seasonal distribution of Anopheles funestus chromosomal forms from Burkina Faso

Abstract Background Previous studies of Anopheles funestus chromosomal inversion polymorphisms in Burkina Faso showed large departures from Hardy-Weinberg equilibrium and linkage disequilibrium among inversions located on different chromosomes, implying the existence of two taxonomic units ("chromosomal forms") with limited genetic flow. One chromosomal form, named Folonzo, is highly polymorphic for alternative rearrangements of 3R a, 3R b, 2R a, and 3L a; the other, Kiribina, is predominantly characterized by the standard arrangement of these inversions. To investigate the temporal distribution of these chromosomal forms, further collections were carried out in two villages near Ouagadougou where they are found in sympatry. Methods Chromosomal karyotypes were determined from indoor-resting, half-gravid females sampled within and across six breeding seasons, from December 1998 to April 2007. Results As expected, the pattern of chromosomal polymorphism in An. funestus was consistent with assortatively mating Folonzo and Kiribina forms. When samples were assigned to each chromosomal form, their relative abundance varied within successive breeding seasons in a repeating pattern of temporal variability. Relative abundance of the Folonzo form was correlated with climatic variables related to temperature and rainfall. Conclusion The relative abundance of Folonzo and Kiribina forms of An. funestus likely reflects different larval ecologies that are linked to varying climatic conditions. Further analysis of the bionomics of these vectors is recommended in light of its relevance to vector control.http://deepblue.lib.umich.edu/bitstream/2027.42/112459/1/12936_2009_Article_987.pd

Machine Learning Approach for Care Improvement of Children and Youth with Type 1 Diabetes Treated with Hybrid Closed-Loop System

Type 1 diabetes is a disease affecting beta cells of the pancreas and it’s responsible for a decreased insulin secretion, leading to an increased blood glucose level. The traditional method for glucose treatment is based on finger-stick measurement of the blood glucose concentration and consequent manual insulin injection. Nowadays insulin pumps and continuous glucose monitoring systems are replacing them, being simpler and automatized. This paper focuses on analyzing and improving the knowledge about which Machine Learning algorithms can work best with glycaemic data and tries to find out the relation between insulin pump settings and glycaemic control. The dataset is composed of 90 days of recordings taken from 16 children and adolescents. Three Machine Learning approaches, two for classification, Logistic Regression (LR) and Random Forest (RL), and one for regression, Multivariate Linear Regression (MLR), have been used for the purpose. Specifically, the pump settings analysis was performed based on the Time In Range (TIR) computation and comparison consequent to pump setting changes. RF and MLR have shown the best results, while, for the settings’ analysis, the data show a discrete correlation between changes and TIRs. This study provides an interesting closer look at the data recorded by the insulin pump and a suitable starting point for a thorough and complete analysis of them

Calidad ambiental en un río urbano de llanura

Environmental quality in a lowland urban river. Ecological integrity or health of a river is evaluated not only by the physical chemical and biological characteristics in the fluvial channel but also by the state of the riparian systems. Attributes of the benthic communities and the riparian areas are integrated to the chemical macroindicators. The objective of this work is to evaluate the environmental quality of the Chocancharava river plain reach in the urban sector and surroundings of Río Cuarto city. Three study sites were selected: in pre-urban, urban and post-urban reaches. Sampling and field data collections were made in two different hydrological periods: winter and summer. Physical and chemical data were registered and benthos samples were taken from transects across different habitats with a Hess sampler. Multimetric indices from structural attributes such as richness, composition and tolerance/intolerance were calculated. The riparian forest quality (RFQ) was evaluated. The obtained score enabled to describe the ecological status. The physical and chemical indicators showed good water quality and the multimetric indices determined a low impaired biological quality. The application of RFQ index showed an extreme degradation of the riparian system quality. The combination of the indices determined a bad ecological status. The results of this study contribute to corroborate that the Chocancharava river, in the urban sector and its surroundings, presents environmental deterioration, and that remediation and improvement measures are necessary.Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) - Instituto de Limnología "Dr. Raul A.

¿Los cultivos de cobertura pueden modificar el patrón de nodulación de soja (Glycine max L.)?

El patrón de nodulación del cultivo de soja puede ser modificado por factores de manejo como la calidad de rastrojos de los cultivos, la inoculación y la fertilización. Se realizó un ensayo en la EEA INTA Marcos Juárez con diseño en bloques aleatorizados con tres repeticiones para evaluar el efecto de diferentes antecesores invernales: (C) centeno (Secale cereale L.), (V) vicia (Vicia villosa L.) y un testigo (T) sin cultivo de cobertura (CC) en el patrón de nodulación. En suelo se determinó el contenidos de nitratos (NO3-) a la siembra, R2 y R5 de soja, mientras que en planta se midió la relación C/N del residuo superficial, el número de nódulos totales por planta (NNT), el peso seco de nódulos (PN), la materia seca (MS) y el contenido de nitrógeno (N) en R2 y R5. Los datos fueron evaluados estadísticamente a través de un análisis de la varianza y un análisis de regresión lineal. La inclusión de CC no modifico los contenidos de NO3-, la producción de MS y la absorción de N por la planta en los períodos evaluados. La relación C/N del residuo superficial tampoco presentó diferencias estadísticamente significativas, pero fue menor a 25 en el antecesor V en R2 y R5. Los antecesores CC no modificaron el PN, pero si afectaron el NNT. Se observó una relación lineal negativa y significativa entre los contenidos de NO3- a la siembra y el NNT. De esta forma, leguminosas utilizadas como CC pueden modificar componentes del patrón de nodulación.Soybean nodulation could be modified by factors such as quality of crop residues, inoculation and fertilization. A trial was performed in EEA INTA Marcos Juárez with randomized block design with three replications for evaluated the effect of different winter soil management: (R),rye (Secale Cereale L), (V) hairy vetch (Vicia villosa) and control (C) without cover crops (CC) in soybean nodulation. In soil nitrate content (NC) at sowing, R2 and R5 stages was determined, while in soybean plant C/N ratio of soil residues, number of nodules (NN), weight of nodules (WN), soybean dry matter (DM) and soybean nitrogen content (SNC) in R2 and R5 stage was determined. Results were statistically evaluated by analysis of variance and linear regression analysis. CC was not modified the soil nitrate content, DM or SNC in R2 or R5 stages. The C/N ratio of crops residue in V was low 25 at R2 and R5 stages. CC was not modified WN, but changes in NN were observed. A negative relationship between SNC and NN were observed. Thus, legume CC might be modified soybean nodulation.Gerencia de Comunicación e Imagen InstitucionalFil: Navarro, G. Universidad Nacional de Villa María. Facultad de Agronomía.
