Tree profile equations are significantly improved when adding tree age and stocking degree: an example for Larix gmelinii in the Greater Khingan Mountains of Inner Mongolia, northeast China
(Springer Nature, 2020) Artículo / ArtikuluaTree age (AGE) and stocking degree (P) strongly influence tree shape, but their effects have been neglected in most tree profile equations. In addition, data used to build traditional tree profile equations usually do not ... -
Incorporating climate effects in Larix gmelinii improves stem taper models in the Greater Khingan Mountains of Inner Mongolia, northeast China
(Elsevier, 2020) Artículo / ArtikuluaEstimating timber volume and carbon stock in forests is fundamental for silviculture and for accurate estimation of national and global carbon budgets. Taper models are important tools for predicting diameter at any height ... -
Influence of structural defects on the properties of metamagnetic shape memory alloys
The production of µ-particles of Metamagnetic Shape Memory Alloys by crushing and subsequent ball milling process has been analyzed. The high energy involved in the milling process induces large internal stresses and high ... -
Giant stress impedance magnetoelastic sensors employing soft magnetic amorphous ribbons
Soft magnetic amorphous alloys obtained via rapid quenching techniques are widely employed in different technological fields such as magnetic field detection, bio labeling, non-contact positioning, etc. Among them, ... -
Coarse woody debris' invertebrate community is affected directly by canopy type and indirectly by thinning in mixed scots pine-European beech forests
Research Highlights: Thinning and tree species alter the forest floor microclimate by modifying canopy cover, radiation, wind, and humidity. Thus, forest management can directly influence the edaphic mesofauna responsible ... -
Insecticidal activity of bacillus thuringiensis proteins against coleopteran pests
Bacillus thuringiensis is the most successful microbial insecticide agent and its proteins have been studied for many years due to its toxicity against insects mainly belonging to the orders Lepidoptera, Diptera and ... -
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 ... -
Biodiesel synthesis using a novel monolithic catalyst with magnetic properties (K2CO3/γ-Al2O3/Sepiolite/γ-Fe2O3) by ethanolic route
(Elsevier, 2020) Artículo / ArtikuluaA novel magnetic monolithic catalyst based on K2CO3/γ-Al2O3/Sepiolite/γ-Fe2O3 was developed seeking to convert efficiently soybean oil and bioethanol to ethanolic biodiesel and glycerol. The magnetic monolithic was attained ... -
Optimizing the removal of nitrate by adsorption onto activated carbon using response surface methodology based on the central composite design
(Taylor & Francis, 2020) Artículo / ArtikuluaThis study sheds light on the adsorption process for the removal of nitrate ions from synthetic aqueous solutions. This contaminant pose a potential risk to the environment and can cause health effects including cancers ... -
Effect of Cu substitution on the magnetic and magnetic induction heating response of CdFe₂O₄ spinel ferrite
(Elsevier, 2020) Artículo / ArtikuluaIn this work, a comparative study of the effect of Cu on the structural, magnetic and magnetic induction heating response in CdFe2O4 spinel is presented. The ceramic nanoparticles (Cu1−xCdxFe2O4; 0 ≤ x ≤ 1) were synthesized ... -
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 ... -
Reducing SO₂ doses in red wines by using grape stem extracts as antioxidants
SO₂ is a very important wine preservative. However, there are several drawbacks associated with the use of SO₂ in wine. The aim of this work is to evaluate the effect of the partial substitution of SO₂ in the Tempranillo ... -
Stability of phenolic compounds in grape stem extracts
Grape stem is rich in phenolic compounds, especially stilbenes. These antioxidants can be degraded during the storage of grape stem extracts for long periods of time. The aim of this work was to analyze the stability of ... -
Production of aromatic compounds by catalytic depolymerization of technical and downstream biorefinery lignins
Lignocellulosic materials are promising alternatives to non-renewable fossil sources when producing aromatic compounds. Lignins from Populus salicaceae., Pinus radiata and Pinus pinaster from industrial wastes and biorefinery ... -
