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, ...
Mitochondrial chaotic dynamics: Redox-energetic behavior at the edge of stability
(2018-10-18)
Mitochondria serve multiple key cellular functions, including energy generation, redox balance, and regulation of apoptotic cell death, thus making a major impact on healthy and diseased states. Increasingly recognized is ...
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 ...
Geotechnical Characteristics in Road Tunnels of Sierra Valle Fértil. San Juan. Argentina
(2014)
The Sierra de Valle Fertil is located in the west of Argentina (San Juan province). It is being crossed by the National Road 150 that has 40 km in length including six bidirectional road tunnels with a total length of 2000 ...
Differential effects of tianeptine on dorsal hippocampal volume in rats subjected to early stress and variable chronic stress during adulthood (#382)
(2014)
Neonatal maternal separation induces long-term alterations in the hypothalamicpituitary-adrenal axis and may increase vulnerability to depression when a stressful
situation occurs in adulthood. Some studies, have found ...
Correlación entre las propiedades estructurales y la adhesión bacteriana de biomateriales compósito de titanio-hidroxiapatita
(2014)
El éxito de los biomateriales, particularmente para implantes y prótesis óseas, se basa en preparar dispositivos cuyas superficies sea n biointeractivas y
selectivas para que simultáneamente mejoren la función ósea y ...
Fast carbon turnover after logging in the Semi-Arid Chaco forest (Argentina)
(2014)
Although the effect of forest logging on soil organic C (SOC) has been studied across different ecosystems, there is no consensus on the general resulting pattern, showing increases, decreases or not net changes in comparison ...
