Linking ecosystem resistance, resilience, and stability in steppes of North Patagonia
(Elsevier, 2013-01)
The main objective of an ecosystem sustainable management is to preserve its capacity to respond and adapt to current disturbances and/or future changes, and maintain the provision of environmental goods and services. Two ...
Efectos de las pasturas perennes en la estructura de molisoles, de la región semiárida pampeana
(Asociación Argentina de la Ciencia del Suelo, 2021-12-15)
El presente trabajo tiene como objetivo evaluar la condición estructural de suelos influenciados por distintas prácticas de uso. El estudio se desarrolló en la Región Semiárida Pampeana sobre Paleustoles petrocálcicos, se ...
Números de curva de escurrimiento determinados para una microcuenca aforada con suelos argiudoles de permeabilidad moderada
(Asociación Argentina de la Ciencia del Suelo, 2022-07-01)
El escurrimiento asociado a la erosión hídrica determina a menudo un costo ambiental debido a la pérdida de agua, suelo, nutrientes y materia orgánica de las tierras agrícolas, así como el transporte de contami nantes hacia ...
Implicancias y reflexiones del impacto de agentes microbiológicos en cerámicas arqueológicas a partir de un estudio de caso
(Universidad Nacional de Rosario. Facultad de Humanidades y Artes. Escuela de Antropología. Departamento de Arqueología, 2020)
Cultural heritage biodeterioration is an actual research line that it has been poorly studied from an archaeological perspective. However, current archaeometric investigations in pottery materials point to a diversity of ...
A combined rock-magnetic and EPR study about the effects of hydrocarbon-related diagenesis on the magnetic signature of oil shales (Vaca Muerta formation, southwestern Argentina)
(Elsevier Science, 2019-02)
A combined study of rock-magnetism and electronic-paramagnetic resonance (EPR) was performed in core samples from an oil well in the Vaca Muerta Formation (SW Argentina). The aim of this work was to characterize the effects ...
Analysis of Large Deflections of Prominence–CME Events during the Rising Phase of Solar Cycle 24
(Springer, 2020-09)
The analysis of the deflection of coronal mass ejection (CME) events plays an important role in the improvement of the forecasting of their geo-effectiveness. Motivated by the scarcity of comprehensive studies of CME events ...
Characterization, recombinant production and structure-function analysis of NvCI, a picomolar metallocarboxypeptidase inhibitor from the marine nnail Nerita versicolor
(Multidisciplinary Digital Publishing Institute, 2019-08)
A very powerful proteinaceous inhibitor of metallocarboxypeptidases has been isolated from the marine snail Nerita versicolor and characterized in depth. The most abundant of four, very similar isoforms, NvCla, was taken ...
The ectodomains of the lymphocyte scavenger receptors CD5 and CD6 interact with tegumental antigens from Echinococcus granulosus sensu lato and protect mice against secondary cystic echinococcosis
(Public Library of Science, 2018-11-30)
Background: Scavenger Receptors (SRs) from the host’s innate immune system are known to bind multiple ligands to promote the removal of non-self or altered-self targets. CD5 and CD6 are two highly homologous class I SRs ...
Proteoglycans and glycosaminoglycans as regulators of cancer stem cell function and therapeutic resistance
(Wiley Blackwell Publishing, Inc, 2019-06-23)
In contrast to the bulk of the tumor, a subset of cancer cells called cancer stem cells (or tumor-initiating cells) is characterized by self-renewal, unlimited proliferative potential, expression of multidrug-resistance ...
Effect of the intensification of cropping sequences on soil organic carbon and its stratification ratio in contrasting environments
(Elsevier, 2021-01-19)
In environments where continuous agriculture leads to soil organic carbon (SOC) depletion, intensification practices (i.e. polyculture, cover crops (CC), and crop fertilization) have been suggested as strategies to improve ...
