Spread Parameters of the Borer Xylotrechus Arvicola (Olivier) (Coleoptera: Cerambycidae) in a 'Tempranillo' Vineyard in La Rioja (Spain): a Long-Term Study
(Estação Vitivinícola Nacional, 2020)
Xylotrechus arvicola (Olivier) (Coleoptera: Cerambycidae) is a polyphagous xylophagous beetle that is becoming a pest of increasing importance for vineyards in Spain, also because of the wood fungi developing in the galleries ...
Analysis of the Air Quality of the Basque Autonomous Community Using Spatial Interpolation
(MDPI, 2020-05-20)
This work presents the results obtained from a spatial modeling and analysis process on pollutants measured in the air through forty-three monitoring stations located in the three provinces of the Basque Autonomous Community ...
Skills Requirements for the European Machine Tool Sector Emerging from Its Digitalization
(MDPI, 2020-12-13)
Abstract
The machine tool industry, which is the starting point of all the metal producing activities, is presently undergoing rapid and continuous changes as a result of the fourth industrial revolution Industry 4.0. ...
Refractive-Index Profile Reconstruction in Graded-Index Polymer Optical Fibers Using Raman Spectroscopy
(MDPI, 2020-05-14)
This work reports a novel method to create a 3D map of the refractive index of different graded-index polymer optical fibers (GI-POF), measuring the Raman spectra at different points of their transverse sections. Raman ...
Harnessing Deep-Hole Drilling to Fabricate Air-Structured Polymer Optical Fibres
(MDPI, 2019-10-24)
The performance of a precisely controlled drilling technique is critical in the fabrication process of microstructured polymer optical fibres. For the creation of a holey preform, adequate drilling bits with large ...
On the Analysis of Speech and Disfluencies for Automatic Detection of Mild Cognitive Impairment
(Springer, 2020-10)
Alzheimer's disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the so-called Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this previous stage does ...
Health services research in patients with breast cancer (CAMISS-prospective): study protocol for an observational prospective study
(Biomed Central, 2019-01-08)
Background: Though breast cancer remains a major health problem, there is a lack of information on health care provided to patients with this disease and associated costs. In addition, there is a need to update and validate ...
An Optical Fiber Bundle Sensor for Tip Clearance and Tip Timing Measurements in a Turbine Rig
(MDPI, 2013-06)
When it comes to measuring blade-tip clearance or blade-tip timing in turbines, reflective intensity-modulated optical fiber sensors overcome several traditional limitations of capacitive, inductive or discharging probe ...
Fabrication and Characterization of Polymer Optical Fibers Doped with Perylene-Derivatives for Fluorescent Lighting Applications
(MDPI, 2017-08)
Four different dye-doped polymer optical fibers (POFs) have been fabricated following a two-step fabrication process of preform extrusion and fiber drawing, using poly-(methyl methacrylate) (PMMA) as host material and dye ...
Polymer-Optical-Fiber Lasers and Amplifiers Doped with Organic Dyes
(MDPI, 2011-09)
Polymer optical fibers (POFs) doped with organic dyes can be used to make efficient lasers and amplifiers due to the high gains achievable in short distances. This paper analyzes the peculiarities of light amplification ...
