Cardiometabolic risk through an integrative classification combining physical activity and sedentary behavior in European adolescents: HELENA study
(Shangai University Sport, 2019-01)
Purpose: This study aims to compare adolescents' cardiometabolic risk score through an integrative classification of physical activity (PA), which involves the combination of moderate-to-vigorous physical activity (MVPA) ...
Numerical Model for Predicting Bead Geometry and Microstructure in Laser Beam Welding of Inconel 718 Sheets
(MDPI, 2018-07)
A numerical model was developed for predicting the bead geometry and microstructure in laser beam welding of 2 mm thickness Inconel 718 sheets. The experiments were carried out with a 1 kW maximum power fiber laser coupled ...
Development of an Intra-Layer Adaptive Toolpath Generation Control Procedure in the Laser Metal Wire Deposition Process
(MDPI, 2019-02-01)
Recently developed concentric laser metal wire deposition (LMWD) heads allow metal addition processes which are independent of the deposition direction, thus enabling complex paths to be generated. The sensitivity of the ...
Combination of Laser Material Deposition and Laser Surface Processes for the Holistic Manufacture of Inconel 718 Components
(MDPI, 2018-07)
The present work proposes a novel manufacturing technique based on the combination of Laser Metal Deposition, Laser Beam Machining, and laser polishing processes for the complete manufacturing of complex parts. Therefore, ...
Formation of Palygorskite Clay from Treated Diatomite and its Application for the Removal of Heavy Metals from Aqueous Solution
(MDPI, 2018-09-15)
Environmental contamination by toxic heavy metals is a serious worldwide phenomenon. Thus, their removal is a crucial issue. In this study, we found an efficient adsorbent to remove Cu2+ and Ni2+ from aqueous solution using ...
The energy requirements of a developed world
(Elsevier, 2016-08)
Through history, special attention has been paid to the study of the relationship between the energy use of a country and its level of development. While the interest of this research area is unquestionable, the energy ...
Correlative super-resolution fluorescence and electron microscopy using conventional fluorescent proteins in vacuo
(Elsevier, 2017-08)
Super-resolution light microscopy, correlative light and electron microscopy, and volume electron microscopy are revolutionising the way in which biological samples are examined and understood. Here, we combine these ...
Association of Notch-1, osteopontin and stem-like cells in ENU-glioma malignant process
(Impact Journals LLC, 2018-07-31)
Notch-1 and osteopontin (OPN) mediate angiogenesis and glioma stem-like cell (GSLC) maintenance. However, the relationship between these molecules and GSLCs during the development of glioma is unknown. We investigate the ...
Functionalization of Cellulose Nanocrystals in Choline Lactate Ionic Liquid
(MDPI, 2016-06)
Cellulose nanocrystals (CNCs) are valuable nanomaterials obtained from renewable resources. Their properties make them suitable for a wide range of applications, including polymer reinforcement. However, due to their highly ...
