Fatty acid composition of skeletal muscle and adipose tissue in Spanish infants and children
(Cambridge University Press, 2006-01)There is a relationship between the fatty acid profile in skeletal muscle phospholipids and peripheral resistance to insulin in adults, but similar data have not been reported in infancy and childhood. The objective of ... -
Fatty Acid Profile of Mature Red Blood Cell Membranes and Dietary Intake as a New Approach to Characterize Children with Overweight and Obesity
(MDPI, 2020-11-10)Obesity is a chronic metabolic disease of high complexity and of multifactorial origin. Understanding the effects of nutrition on childhood obesity metabolism remains a challenge. The aim of this study was to determine the ... -
Fault-tolerant almost exact state transmission
(Nature Publishing Group, 2013-11)We show that a category of one-dimensional XY-type models may enable high-fidelity quantum state transmissions, regardless of details of coupling configurations. This observation leads to a fault-tolerant design of a state ... -
Favoring Trienamine Activation through Unconjugated Dienals: Organocatalytic Enantioselective Remote Functionalization of Alkenes
(Wiley-VCH, 2014-01-29)Unconjugated 2,5-dienals are more reactive substrates than the corresponding fully conjugated a,b,g,dunsaturated aldehydes towards organocatalytic activation through trienamine intermediates. This difference in ... -

Fe xCo1-x alloy nanoparticles: Synthesis, structure, magnetic characterization and magnetorheological application
(Elsevier, 2022-12)We present results concerning the synthesis of FexCo1-x (0 < x < 1) alloy nanoparticles (NPs) with different compositions by the chemical reduction technique and subsequent structural (XRD patterns), morphological (TEM ... -
Fe(III) Biomineralization in the Surface Microlayer of Acid Mine Waters Catalyzed by Neustonic Fe(II)-Oxidizing Microorganisms
(MDPI, 2023-04-01)The formation of thin mineral films or encrustations floating on the water surface of low-flow or stagnant zones of acid mine drainage (AMD)-affected streams is probably among the most exotic features that can be found in ... -
Fe/Olivine As Primary Catalyst in the Biomass Steam Gasification in a Fountain Confined Spouted Bed Reactor
(Elsevier, 2021-07-25)The performance of Fe/olivine catalysts was tested in the continuous steam gasification of sawdust in a bench scale plant provided with a fountain confined conical spouted bed reactor at 850 degrees C. Olivine was used as ... -
Feasibility Assessment of a Fine-Grained Access Control Model on Resource Constrained Sensors
(MDPI, 2018-02-13)Upcoming smart scenarios enabled by the Internet of Things (IoT) envision smart objects that provide services that can adapt to user behavior or be managed to achieve greater productivity. In such environments, smart things ... -
Feasibility of the capnogram to monitor ventilation rate during cardiopulmonary resuscitation
(Elsevier, 2017-01)Aim:The rates of chest compressions (CCs) and ventilations are both important metrics to monitor the quality of cardiopulmonary resuscitation (CPR). Capnography permits monitoring ventilation, but the CCs provided during ... -
