Hambre y Derecho a la Alimentación: la agenda 2030 en Centroamérica y la República Dominicana

Al abordar el problema del hambre y la desnutrición, la más reciente Conferencia Regional sobre Desarrollo Social de América Latina y el Caribe organizada por la CEPAL (Lima, Perú, 2 a 4 de noviembre de 2015) puso énfasis en la necesidad de tratar estos asuntos desde la óptica del derecho a la alimentación, establecido en la Declaración Universal de los Derechos Humanos y el Pacto de Derechos Económicos, Sociales y Culturales. En el documento preparatorio de dicha conferencia se señala que el Objetivo 2 de los Objetivos para el Desarrollo Sostenible es relevante en tanto aborda la problemática de la alimentación y la nutrición de una manera más integral y considera la seguridad alimentaria como un derecho humano fundamental, cuya conculcación limita la capacidad de ejercicio de los derechos políticos y el desarrollo de una democracia participativa. En línea con este planteamiento, uno de los objetivos principales de este estudio es conocer el estado del arte que en la subregión ha tenido el enfoque de derechos en las políticas de seguridad alimentaria y nutricional y, en particular, la promoción del derecho humano a la alimentación,

Estudo geofísico em um depósito de manganês supergênico no município de Itapira - SP

The mining research is a complex activity, which should preferably involve the combination of direct and indirect techniques of geological research. The increasing demand for base metals in domestic and international markets provide the revaluation of mineral occurrences, which can be converted into deposits and mines. This paper presents the results of the application of geophysical methods of electric resistivity and induced polarization in main foliation parallel to the arrangement of the area, in a deposit of oxides and hydroxides in massive and disseminated ores, docked in gneisses and quartzites, located in the municipality of Itapira, in the North of the State of São Paulo in Brazil. Inversion models indicate the predominance of high cargabilidade that partially coincide with low resistivity values. Integration of geophysical data made possible the drafting of sections of electric walking with cross-checking distance x depth, for detailing your target. The integrated analysis of geophysical and geological structural data leads to the conclusion that the primary mining suffers structural control with the regional foliation in ores

Monitoramento das águas subterrâneas do aterro de resíduos da construção civil e inertes, no bairro Jd. Wenzel, em Rio Claro-SP

This work is proposed to evaluate the potential risk of an inert landfill in the city of Rio Claro (SP), and also suggest a source for the contamination. The study was proposed because it is known that there were legal technicalities greetings to guarantee the quality of groundwater. Given the requirements of the Environmental Company of São Paulo (CETESB) were installed monitoring wells in the area; sampled to groundwater and its contamination was found. In addition, we analyzed the main characteristics of the area, the arrangement and characteristics of the waste, the local geology and the hydrogeological system, so that I could find the source of contaminants, and predict the direction of dispersion even in groundwater. At the end of the work presents conclusions, recommendations and proposals for mitigating action

Controllability and stabilizability of linear time-varying distributed hereditary control systems

This paper is concerned with the controllability and stabilizability problem for control systems described by a time-varyinglinear abstract differential equation with distributed delay in the state variables. An approximate controllability propertyis established, and for periodic systems, the stabilization problem is studied. Assuming that the semigroup of operatorsassociated with the uncontrolled and non delayed equation is compact, and using the characterization of the asymptoticstability in terms of the spectrum of the monodromy operator of the uncontrolled system, it is shown that the approximatecontrollability property is a sufficient condition for the existence of a periodic feedback control law that stabilizes thesystem. The result is extended to include some systems which are asymptotically periodic. Copyright © 2014 John Wiley &Sons, Ltd.

Functional Magnetic Resonance Imaging Data Analysis by Autoregressive Estimator

The autoregressive (AR) estimator, a non-parametric method, is used to analyze functional magnetic resonance imaging (fMRI) data. The same method has been used, with success, in several other time series data analysis. It uses exclusively the available experimental data points to estimate the most plausible power spectra compatible with the experimental data and there is no need to make any assumption about non-measured points. The time series, obtained from fMRI block paradigm data, is analyzed by the AR method to determine the brain active regions involved in the processing of a given stimulus. This method is considerably more reliable than the fast Fourier transform or the parametric methods. The time series corresponding to each image pixel is analyzed using the AR estimator and the corresponding poles are obtained. The pole distribution gives the shape of power spectra, and the pixels with poles at the stimulation frequency are considered as the active regions. The method was applied in simulated and real data, its superiority is shown by the receiver operating characteristic curves which were obtained using the simulated data.

Two new species and a review of the inseminating freshwater fish genus Monotocheirodon (Characiformes: Characidae) from Peru and Bolivia

Two new species of inseminating freshwater fishes of the genus Monotocheirodon, family Characidae, are described from Peru. Males and females of both new species have an external, visually obvious urogenital papilla that was not detected in the females in previous studies, with this longer in males, which use it as an inseminating organ. A third inseminating species from Bolivia, Monotocheirodon pearsoni, unstudied in any detail since its original description in 1924, is redescribed. This latter species lacks an inseminating organ. Monotocheirodon is redescribed, its phylogenetic relationships are briefly discussed and it is suggested that it is possibly related to the stevardiin genera Ceratobranchia, Othonocheirodus, and Odontostoechus.
