Evolución de la enseñanza de las aguas subterráneas en los libros de texto y diseño de una propuesta didáctica para su enseñanza en la educación secundaria
A pesar de que las aguas subterráneas son la mayor fuente de agua dulce líquida en la Tierra, su naturaleza abstracta ha ocasionado que sea el concepto más complicado de entender dentro del ciclo del agua, siendo uno de ... -
Evolution of metakaolin thermal and chemical activation from natural kaolin
In the present paper, we study the combined effect of thermal activation (600 °C/2 h and 750 °C/2 h) and chemical activation with 1% ZnO on the reactivity of metakaolinite (MK) obtained from natural kaolin. The phases are ... -
Experimental and theoretical studies of the interaction of ketoprofen in halloysite nanotubes
In recent years, the application of halloysite (HAL) in the conception of drug systems has become important due to its excellent physicochemical properties. Ketoprofen (KET) is widely used around the world as an anti-inflammatory ... -
Experimental observation of vacancy-assisted martensitic transformation shift in Ni-Fe-Ga alloys
Positron annihilation lifetime spectroscopy is used to experimentally demonstrate the direct relationship between vacancies and the shift of the martensitic transformation temperature in a Ni55Fel7Ga28 alloy. The evolution ... -
Experimental Stark widths and shifts of MnII spectral lines
Stark widths and shifts of MnII lines with wavelengths in the range 2300-3500 Å have been measured by laser-induced breakdown spectroscopy. The use of fused glass samples with varying Mn concentrations has allowed minimization ... -
Experimental stark widths and shifts of V II spectral lines
We have measured the Stark widths and shifts of V II spectral lines in the wavelength range 2000-4200 Å belonging to 75 multiplets. The spectra are emitted by laser-induced plasmas generated from fused glass discs prepared ... -
Exploring a low-cost valorization route for amazonian cocoa pod husks through thermochemical and catalytic upgrading of pyrolysis vapors
Ecuador as an international leader in the production of cocoa beans produced more than 300 000 tons in 2021; hence, the management and valorization of the 2 MM tons of waste generated annually by this industry have a ... -
Exploring the conceptual challenges of integrating epigenetics in secondary-level science teaching
Rapidly occurring advancements in molecular genetics, such as recent developments in epigenetics, are challenging traditional genetics as it is taught at schools. For example, the adoption of epigenetics—which ... -
Exploring the potential of the dynamic hysteresis loops via high field, high frequency and temperature adjustable AC magnetometer for magnetic hyperthermia characterization
Aim: The Specific Absorption Rate (SAR) is the key parameter to optimize the effectiveness of magnetic nanoparticles in magnetic hyperthermia. AC magnetometry arises as a powerful technique to quantify the SAR by computing ... -
Extraction of phenolic compounds from populus salicaceae bark
Lignocellulosic residues have the potential for obtaining high value-added products that could be better valorized if biorefinery strategies are adopted. The debarking of short-rotation crops yields important amounts of ... -
Extruded catalysts with magnetic properties for biodiesel production
The aim of this work was to evaluate the performance of different extruded catalysts containing K2CO3 as active phase and adding conveniently γ-Al2O3 and/or sepiolite and magnetic particles on the biodiesel production from ... -
Facile synthesis of an Ni/LaAlO3 - perovskite via an MOF gel precursor for the dry reforming of methane
A simple strategy to prepare the pure perovskite phase of lanthanum aluminate (LaAlO3) by calcination of a highly porous, dry MOF precursor gel has been developed. This study demonstrates that the structural and textural ... -
Fe-C nanoparticles obtained from thermal decomposition employing sugars as reducing agents
The aim of the work is to present a comparative analysis (structural and magnetic) of Fe-C nanocomposites obtained by the thermal decomposition of sugars (fructose, glucose and sucrose) employing FeCl3 as Fe3+ precursor. ... -
Feasibility to producing second generation bioethanol in Bolivia
Bioethanol produced worldwide is mostly obtained from agricultural crops such as sugarcane and corn. However, it has negative environmental effects, so opportunity for producing bioethanol from agricultural waste arises. ... -
A fermented food product containing lactic acid bacteria protects ZDF rats from the development of type 2 diabetes
Type 2 diabetes (T2D) is a complex metabolic disease, which involves a maintained hyperglycemia due to the development of an insulin resistance process. Among multiple risk factors, host intestinal microbiota has received ... -
A fertilisation strategy combining mineral fertiliser and biosolid improves long-term yield and carbon storage in a calcareous soil
At a strategic moment for agricultural soils, which are expected to contribute to climate change mitigation through carbon storage while safely feeding a growing world population, the fertiliser strategies used will be ... -
Flipped Classroom como herramienta para fomentar el trabajo colaborativo y la motivación en el aprendizaje de geología
Vivimos en una sociedad global y multicultural, lo que hace necesario que el profesorado se adapte a esta nueva realidad y asuma cambios profundos en sus prácticas educativas. En este contexto, las TIC pueden ayudar a los ... -
Forest recovery through applied nucleation: effects of tree islet size and disperser mobility on tree recruitment in a temperate landscape
The plantation of tree islets within deforested areas (applied nucleation) has been proposed as a restoration strategy able to catalyze tree colonization in the matrix with reasonable costs and labor compared to traditional ... -
