• Modeling the onset of photosynthesis after the Chicxulub asteroid impact 

    Pérez Díaz, Noel; Cárdenas Ortiz, Rolando; Martín González, Osmel; Rojas Consuegra, Reinaldo (2013)
    We do a preliminary modelling of the photosynthetic rates of phytoplankton at the very beginning of the Paleogene, just after the impact of the Chicxulub asteroid, which decisively contributed to the last known mass ...
  • The potential for photosynthesis in hydrothermal vents: a new avenue for life in the universe? 

    Pérez Díaz, Noel; Cárdenas Ortiz, Rolando; Martín González, Osmel; Leiva Mora, Michel (2013)
    We perform a quantitative assessment for the potential for photosynthesis in hydrothermal vents in the deep ocean. The photosynthetically active radiation in this case is from geothermal origin: the infrared thermal ...
  • On the habitability of aquaplanets 

    Cárdenas Ortiz, Rolando; Pérez Díaz, Noel; Martinez Frias, Jesus; Martín González, Osmel (2014)
    An Aquatic Habitability Index is proposed, based on Quantitative Habitability Theory, and considering a very general model for life. It is a primary habitability index, measuring habitability for phytoplankton in the first ...
  • Evolución del proceso de fotosíntesis después del impacto del asteroide de Chicxulub 

    Pérez Díaz, Noel; Martín González, Osmel; Cárdenas Ortiz, Rolando (2014)
    Se evalua como pudo evolucionar el proceso de la photosíntesis del fitoplancton después de un evento catastrófico como el impacto del asteroide de Chicxulub, emploeándose el modelo E de fotosíntesis para fitoplancton con ...
  • Geodiversity, Heritage, and Geoethics in an Archipelago 

    Rojas Consuegra, Reinaldo; Mengana, Jorge Isaac; Cárdenas Ortiz, Rolando; Nuñez Cambra, Kenya E.; Pérez Díaz, Noel; Martín González, Osmel (Springer, 2018)
    The Cuban archipelago has an extremely complex geology. In this chapter, an overview on its peculiarities is given. It is also presented a historical sketch of the Cuban geological heritage, and the current menaces to ...
  • The mass impacts on chemosynthetic primary producers: potential implications on anammox communities and their consequences 

    Pérez Díaz, Noel; Velazco Vargas, Jorge Luis; Martín González, Osmel; Cárdenas Ortiz, Rolando; Martínez Frías, Jesús (2018)
    The potential of a mass asteroid impact on Earth to disturb the chemosynthetic communities at global scale is discussed. Special emphasis is made on the potential influence on anammox communities and their implications in ...
  • Experiencias en el uso de la Práctica Proyecto en la disciplina Física Experimental 

    Morales González, Williams; Gutiérrez Pérez, Jose Daniel; Hernández Ruiz, Jesús Eleuterio (2018-05)
    En la presente ponencia se presentan las experiencias del colectivo de la disciplina Física Experimental de la carrera de Licenciatura en Física de la Universidad Central de Las Villas en el uso de la Práctica Proyecto. ...
  • On the quantification of habitability: current approaches 

    Cárdenas Ortiz, Rolando; Nodarse Zulueta, Rosmery; Pérez Díaz, Noel; Avila Alonso, Daile; Martín González, Osmel (Springer, 2019)
    In this chapter, we outline general ideas to quantify habitability, starting with a general abiogenesis–biogenesis conceptual model. We connect this model with the approach of the astrobiological school of quantitative ...
  • Enlarging simple ecological models:subspecies, hidden symmetries and thei implications 

    Martín González, Osmel; Pérez Díaz, Noel; Cárdenas Ortiz, Rolando; Horvath, J.E. (Springer, 2019)
    Some basic principles to enlarge simple ecological models and the role of nonlinearities are discussed. The inclusion of internal groups and the new dynamic possibilities associated with this procedure are considered in ...
  • Potential changes on anammox activity after Chicxulub asteroid impact 

    Pérez Díaz, Noel; Martín González, Osmel; Cárdenas Ortiz, Rolando (Springer, 2019)
    The activity of anammox bacteria (AA) can be estimated based on the production of N2. Known the mechanism of the catabolic reaction, three differential equations are established according to the most important substrates ...
