(FLASCO-MEXICO, 2020)This research develops a methodological a perspective to evaluate the impact of conditional cash transfer programs, due to the need to broaden the understanding of social change and identify, describe and explain the social ... -
Nuevo varamiento masivo de orca falsa, Pseudorca crassidens, en el Estrecho de Magallanes, Chile
(CIENCIAS, 2015)We report the mass stranding of 46 false killer whales in the Strait of Magellan in February 2013. We present observation-based information about body size, sex, dental formula and necropsies. Sexual dimorphism in body ... -
Numerical processing profiles in children with varying degrees of arithmetical achievement
(ELSEVIER, 2019)Recent studies show basic cognitive abilities such as the rapid and precise apprehension of small numerosities in object sets ("subitizing"), verbal counting and numerical magnitude comparison significantly influence the ... -
Numerical skills and dyscalculia. From basic research to practice in Cuba
(Taylor and Francis Ltd., 2020-06)Establishing bridges between the findings from cognitive neurosciences and teaching practice has not been systematically achieved. However, many researchers interested in this area agree on the positive impact that knowledge ... -
Nursing Consultation in a Public Bathhouse: A Community Resource for the Vulnerable Population in a European Capital
(TAYLOR & FRANCIS INC, 2019)Background: In Portugal's capital, Lisbon, there are 19 public showers (PS) attended by a vulnerable population. Aim: To describe the assessment and interventions performed during nursing consultations. Method: This is a ... -
Nutrient dose-responsive transcriptome changes driven by Michaelis Menten kinetics underlie plant growth rates
(National Academy of Sciences, 2020-06-09)An increase in nutrient dose leads to proportional increases in crop biomass and agricultural yield. However, the molecular underpinnings of this nutrient dose-response are largely unknown. To investigate, we assayed changes ... -
Nutrient Transport Driven by Microbial Active Carpets
(AMER PHYSICAL SOC, 2018)We demonstrate that active carpets of bacteria or self-propelled colloids generate coherent flows towards the substrate, and propose that these currents provide efficient pathways to replenish nutrients that feed back into ... -
Nutritional ecology and ecological immunology in degus: Does early nutrition affect the postnatal development of the immune function?
(WILEY, 2021-02)Environmental conditions experienced by developing animals have an impact on the development and maturity of the immune system. Specifically, the diet experienced during early development influences the maintenance and ... -
Nutritional status and sweet taste preference in Chilean adults
(ARCHIVOS LATINOAMERICANOS NUTRICION, 2020-12)El dramático aumento de la prevalencia e incidencia de la obesidad sugiere que factores ambientales y cambios en el estilo de vida contribuyen de forma importante a su tendencia epidémica. En humanos, se han reportado ... -
Nutritional status differentially affect yield and must composition of hybrids and V. vinifera varieties established under cold climate conditions
(ESTACAO VITIVINICOLA NACIONAL, 2021-09)Nova Scotia is characterized by cold climate and acidic soils and high organic matter for viticultural development. There is little scientific information available about the nutritional management of grapevine varieties ... -
