    • Evaluación de la aplicación de biosólidos en plantaciones de Eucalyptus globulus, en Chile central 
      Donoso Calderón, Sergio; Peña Rojas, Karen; Galdames Palma, Evelyn; Pacheco Fuentes, Cristian; Espinoza Cayulen, Claudia; Durán Adasme, Sergio; Gangas Fuentealba, Rodrigo (Universidad Nacional de Cuyo, Facultad Ciencias Agrarías, 2016)
      Fertilization with biosolid is an option for beneficial use of waste generated from wastewater treatment plant. At this point of view, it is necessary know its effect in forest plantations. The study was established in two ...
    • Evidences for the presence of chymotrypsin‐like activity in human spermatozoa with a role in the acrosome reaction 
      Torres Morales, Patricio; Socias, Teresa; Cortez, Jacqueline; Llanos Silva, Miguel (1994)
      The effect of chymotrypsin inhibitors and substrates on the human sperm acrosome reaction stimulated by the human zonae pellucidae or follicular fluid were evaluated. Motile spermatozoa, selected by a Percoll gradient, ...
    • Linking above-ground biomass production to below-ground carbon fluxes across stocking, clone, fertilization, ... 
      Mohan, K. C; Mason, Euan G.; Bown Intveen, Horacio (Elsevier, 2020)
      The linkage between above-ground biomass production and below-ground carbon fluxes as influenced by silviculture has been insufficiently studied. We tested the effects of stocking, clone, fertilization, and follow-up ...
    • Pinus radiata D. Don in Chile. Fertilization trials with copper 
      Gonzalez, C.; Escobar, R.; Lachica, M. (Martinus Nijhoff, The Hague/Kluwer Academic Publishers, 1987)
      Young Pinus radiata D. Don were fertilized with copper oxychloride and copper sulfate on a random block basis with four replicates. Roots, needles, stems and shoot apices were analyzed separately for Cu, Fe, Mn and Zn ...
    • Scientific ethics of human origin Etica científica del origen humano 
      Valenzuela, Carlos Y. (1997)
      The analysis of the early human life from the view point of a scientific ethics is presented. Life is a historical materioenergetic process of specific organization. This phylo-ontogenetic process is a continuos process ...
    • Southern Ocean carbon sink enhanced by sea-ice feedbacks at the Antarctic Cold Reversal 
      Fogwill, C. J.; Turney, C. S. M.; Menviel, L.; Baker, A.; Weber, M. E.; Ellis, B.; Thomas, Z. A.; Golledge, N. R.; Etheridge, D.; Rubino, M.; Thornton, D. P.; van Ommen, T. D.; Moy, A. D.; Curran, M. A. J.; Davies, S.; Bird, M., I; Munksgaard, N. C.; Rootes, C. M.; Millman, H.; Vohra, J.; Rivera, A.; Mackintosh, A.; Pike, J.; Hall, I. R.; Bagshaw, E. A.; Rainsley, E.; Bronk-Ramsey, C.; Montenari, M.; Cage, A. G.; Harris, M. R. P.; Jones, R.; Power, A.; Love, J.; Young, J.; Weyrich, L. S.; Cooper, A. (Nature, 2020)
      Increased Southern Ocean productivity driven by sea-ice feedbacks contributed to a slowdown in rising CO(2)levels during the last deglaciation, according to analyses of marine-derived aerosols from an Antarctic ice ...
    • Stem and soil CO2 efflux responses of Pinus radiata plantations to temperature, season, age, time (day/night) ... 
      Bown Intveen, Horacio; Watt, Michael (Pontificia Universidad Católica de Chile. Facultad de Agronomía Ingeniería Forestal, 2016)
      Stem CO2 efflux is a highly variable component of the carbon budget of forest ecosystems. It reflects the balance between the CO2 respired by the living stem tissues, less the CO2 dissolved in the xylem sap moving upward ...
    • The acrosome reaction-inducing activity of individual human follicular fluid samples is highly variable and ... 
      Torres Morales, Patricio; Llanos Silva, Miguel; Gutierrez, Gabriela; Kohen Skop, Paulina; Vigil, Pilar; Vantman, David (Oxford University Press, 1992)
      In this study, we have evaluated the relationship between the acrosome reaction-inducing activity of individual human follicular fluid samples and their steroid content. Eighteen samples of follicular fluid were obtained ...
    • Typologies and arguments about the use of assisted reproductive technologies among people living in Santiago, ... 
      Herrera, Florencia; Teitelboim, Berta; Zegers-Hochschild, Fernando (Sociedad Medica de Santiago, 2015)
      © 2015, Sociedad Medica de Santiago. All rights reserved. Background: Assisted reproductive technologies still generate debate about ethical moral and religious issues. Aim: To analyze the opinions of the general public ...
