Effects of native plants extracts from Córdoba Argentina over foraging activity of the cutting ant Acromyrmex lundi (Guérin)
(2013)
In the search for new alternatives for insect pest management, natural products from plants are an option currently studied for being substances of low toxicity and biodegradable. The leaf-cutting ant Acromyrmex lundi is ...
Suffusion in compacted loessial silts. Interaction with granular filters
(2013)
Loess soils, which occupies much of central Argentina, is characterized by its high sensitivity to change in moisture. This condition categorized loess structure as internally unstable soil. Despite this ...
A 6-bit 2GS/s CMOS Time-Interleaved ADC for Analysis of Mixed-Signal Calibration Techniques
(2014)
A 6-bit 2-GS/s time interleaved (TI) successive approximation register (SAR) analog-to-digital converter (ADC) is designed and fabricated in a 0.13 μm CMOS process. The architecture uses 8 time-interleaved track-and-hold ...
A new approach to segmentation of remote sensing images with hidden markov models
(2014)
In this work, we present a new segmentation algorithm for remote sensing images based on two-dimensional Hidden Markov Models (2D-HMM). In contrast to most 2D-HMM approaches, we do not use Viterbi Training, instead we ...
Crossing regions for supersonic cones
(2014)
The original study of a conical body of circular cross section at zero angle of attack inside a supersonic flow was developed by Taylor & Maccoll 1933, see [1]. After this year a large amount of numerical and perturbation ...
Yeasts as biocatalysts in the stereoselective reduction of acetophnone
(2015)
The asymmetric reduction of prochiral ketones represents a pivotal transformation for the
production of chiral alcohols. Several of them are considered as key starting materials in obtaining
of pharmaceuticals. Nowadays, ...
Minor Street Gaps and Capacity at Unsignalized Intersections in Argentina
(2012)
Capacity analysis for two way stop controlled (TWSC) intersections is mainly based on headway acceptance theory. Critical headways and follow up times are fundamental parameters in capacity estimation. Both factors clearly ...
Algorithm model and execution based on Petri Nets in an heterogeneous parallel computer
(2014)
Multicore - MultiGPU systems are frequently used in supercomputers design. The heterogeneity between both types of processors is a source of problems for the parallel programming: disparity in processing throughput and ...
The hydrochemical and isotopic signature of the Middle Paraná River downflow the confluence of Paraguay and Upper Paraná rivers: surface water mixing or groundwater inflow?
(2014)
The Paraná River basin is one of the largest hydrological systems in South America (~2.6
x 106

). Most large rivers exhibit transverse and longitudinal inhomogeneities downflow
the confluence of tributaries, which ...
Dynamic model for the analysis of productive enviroments in a pseudo crisis phase: The case of demographic ageing
(2013)
: In this paper, the hypothesis of an increasing elderly productive population is assumed in order to preserve the dynamical equilibrium between costs and production in the context of ageing on labour markets that takes ...
