La inversión en renta fija. Una clarificación del riesgo que supone su adquisición
(Area Innovación & Desarrollo, 2021-02)
[Resumen] La renta fija tiende a ser asociada con un activo libre de riesgo y cuya rentabilidad es conocida de antemano. Pese a ello, no debe identificarse a la renta fija con estas cualidades, al igual que tampoco debe ...
Near Room Temperature Dielectric Transition in the Perovskite Formate Framework [(CH₃)₂NH₂][Mg(HCOO)₃]
(The Royal Society of Chemistry, 2012-05)
[Abstract] We report that the hybrid organic–inorganic compound [(CH₃)₂NH₂][Mg(HCOO)₃] shows a marked dielectric transition around Tₜ ∼ 270 K, associated to a structural phase transition from SG R[3 with combining macron]c ...
A Logistic Approach for Kinetics of Isothermal Pyrolysis of Cellulose
(MDPI, 2021-03)
[Abstract] A kinetic model is proposed to fit isothermal thermogravimetric data obtained from cellulose in an inert atmosphere at different temperatures. The method used here to evaluate the model involves two steps: (1) ...
Properties of Mosquito Repellent-Plasticized Poly(lactic acid) Strands
(MDPI, 2021-09)
[Abstract] Poly(lactic acid) (PLA) is an attractive candidate for replacing petrochemical polymers because it is fully biodegradable. This study investigated the potential of PLA as a sustainable and environmentally friendly ...
A relatively simple look at the rather complex crystallization kinetics of PLLA
(MDPI, 2023-04-14)
[Abstract] This work demonstrates that, despite the existence of a significant number of works on PLA crystallization, there is still a relatively simple way, different from those already described, in which its complex ...
Dynamic rheological comparison of silicones for podiatry applications
(Elsevier, 2018-05-26)
[Abstract]: This work shows an effective methodology to evaluate the dynamic viscoelastic behavior of silicones for application in podiatry. The aim is to characterize, compare their viscoelastic properties according to ...
Crystallization kinetics of a commercial poly(lactic acid) based on characteristic crystallization time and optimal crystallization temperature
(Springer, 2020-07-23)
[Abstract]: A model is proposed to fit differential scanning calorimetry (DSC) isothermal crystallization curves obtained from the molten state at different temperatures. A commercial 3D printing polylactic acid (PLA) ...
The effect of marine ageing on the mechanical properties of a structural adhesive
(Springer, 2023)
[Abstract] The aim of this work is to study the behaviour of a structural adhesive in an aggressive setting such as the marine environment. For this purpose, an ageing procedure is carried out under marine environmental ...
Thermal and rheological comparison of adhesives
(Springer, 2019-10-10)
[Abstract]: In some industrial sectors such as naval construction, the use of adhesives is still limited to some specific applications. However, shipbuilders, academia and classification societies are cooperating to expand ...
Lecciones de la crisis. Hacia un nuevo enfoque en el análisis del proceso de endeudamiento empresarial
(Universidade de Santiago de Compostela, 2012)
[Resumen]: Uno de los aspectos cruciales de la actual crisis es el excesivo endeudamiento adquirido por los diversos agentes de la economía. Llama la atención que en el período de expansión, en el que la deuda asumida iba ...
