Crystallization of isodimorphic aliphatic random copolyesters: pseudo-eutectic behavior and double-crystalline materials
(Elservier, 2018-02-28)
Isodimorphic random copolyesters are intriguing polymeric materials that can crystallize in their entire composition range, despite the random distribution of comonomer units along their chains. This behavior stems from ...
Association of Birth Order with Cardiovascular Disease Risk Factors in Young Adulthood: A Study of One Million Swedish Men
(Public Library of Science, 2013-05-16)
Background: Birth order has been suggested to be linked to several cardiovascular disease (CVD) risk factors, but the evidence is still inconsistent. We aim to determine the associations of birth order with body mass index ...
Mean Stress Effect on the Axial Fatigue Strength of DIN 34CrNiMo6 Quenched and Tempered Steel
(MDPI, 2018-04)
The present study consists of a theoretical and experimental investigation of the effect of axial mean stresses on the high cycle fatigue behaviour of DIN 34CrNiMo6 high strength steel in quenched and tempered conditions. ...
Secure Protocol and IP Core for Configuration of Networking Hardware IPs in the Smart Grid
(MDPI, 2018-03)
Nowadays, the incorporation and constant evolution of communication networks in the electricity sector have given rise to the so-called Smart Grid, which is why it is necessary to have devices that are capable of managing ...
Putative Role of Respiratory Muscle Training to Improve Endurance Performance in Hypoxia: A Review
(Frontiers Media, 2019-01-15)
Respiratory/inspiratory muscle training (RMT/IMT) has been proposed to improve the endurance performance of athletes in normoxia. In recent years, due to the increased use of hypoxic training method among athletes, the RMT ...
Experimental Validation of the Kinematic Design of 3PRS Compliant Parallel Mechanisms
(Elsevier, 2016-11)
In this paper, a procedure for the kinematic design of a 3-PRS compliant parallel manipulator of 3 degrees of freedom is proposed. First, under the assumption of small displacements, the solid body kinematics of the 3-PRS ...
High-Altitude Cognitive Impairment Is Prevented by Enriched Environment Including Exercise via VEGF Signaling
(Frontiers Media, 2019)
Exposure to hypobaric hypoxia at high altitude (above 2500 m asl) causes cognitive impairment, mostly attributed to changes in brain perfusion and consequently neuronal death. Enriched environment and voluntary exercise ...
Optimizing Biodiesel Production from Waste Cooking Oil Using Genetic Algorithm-Based Support Vector Machines
(MDPI, 2018-11-01)
The ever increasing fuel demands and the limitations of oil reserves have motivated research of renewable and sustainable energy resources to replace, even partially, fossil fuels, which are having a serious environmental ...
Cosmological Perturbations in Phantom Dark Energy Models
(MDPI, 2017-03-06)
The CDM paradigm, characterised by a constant equation of state w = -1 for dark energy, is the model that better fits observations. However, the same observations strongly support the possibility of a dark energy content ...
Observation of TransverseΛ= ̄ΛHyperon Polarization ine+e−Annihilation at Belle
(American Physical Society, 2019-01-29)
We report the first observation of the spontaneous polarization of Lambda and (Lambda) over bar hyperons transverse to the production plane in e(+)e(-) annihilation, which is attributed to the effect arising from a polarizing ...
