Post-task Effects on EEG Brain Activity Differ for Various Differential Learning and Contextual Interference Protocols
2017
A large body of research has shown superior learning rates in variable practice compared to repetitive practice. More specifically, this has been demonstrated in the contextual interference (CI) and in the differential learning (DL) approach that are both representatives of variable practice. Behavioral studies have indicate different learning processes in CI and DL. Aim of the present study was to examine immediate post-task effects on electroencephalographic (EEG) brain activation patterns after CI and DL protocols that reveal underlying neural processes at the early stage of motor consolidation. Additionally, we tested two DL protocols (gradual DL, chaotic DL) to examine the effect of di…
A Biologically Inspired Representation of the Intelligence of a University Campus
2016
Abstract Intelligence or smartness in an urban environment implies several factors directed to improve quality of life and efficiency. It is important to note that in this context the inclusion of citizens and their devices is a key factor for reaching smartness. Data from mobile devices are increasingly used in everyday activities and have to be considered a useful means for handling and analyzing knowledge and communications. This paper shows how to represent important data when dealing with smartness by creating an analogy between the representation of human brain areas, activated when specific tasks are performed, and groups of students when behaviors or needs arise. The brain traffic c…
Biowaiver Monograph for Immediate-Release Solid Oral Dosage Forms: Moxifloxacin Hydrochloride.
2020
Abstract In this monograph, literature data is reviewed to evaluate the feasibility of waiving in vivo bioequivalence testing and instead applying the Biopharmaceutics Classification System (BCS) based methods to the approval of immediate-release solid oral dosage forms containing moxifloxacin hydrochloride as the sole active pharmaceutical ingredient. To facilitate the feasibility decision, solubility and permeability and dissolution characteristics in the context of the BCS, therapeutic index, therapeutic use, pharmacokinetic parameters, bioequivalence/bioavailability issues, drug-excipient interactions and other relevant data were taken into consideration. Moxifloxacin is a BCS class I d…
Degradation of stone materials in the archaeological context of the Greek-Roman Theatre in Taormina (Sicily, Italy)
2010
In the present work results on the degradation phenomena of stone materials in the Ancient Theatre of Taormina, one of the most important Greek–Roman monuments of Sicily, are reported. Artificial stone materials in different conservation conditions were investigated. Samples of salt efflorescences from brick walls and degraded setting mortars were taken from the open gallery in “summa cavea”. The chemical, physical and structural characterization was performed by means of X-Ray Photoelectron Spectroscopy (XPS), X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF), both in situ and ex situ. Results showed that the deterioration of stone materials is due to the aggressive action of the enviro…
Social Bricolage as the Path to Social Entrepreneurship
2021
In the present chapter, the concept of social bricolage is applied to the particular case of Dr. Mateo. A contextualization of her environment is exposed, for the reader to understand the intrinsic and extrinsic motivators explained in Part I. These influences represent the starting point of her professional career. Dr. Mateo’s interests have always been placed in advancing local solutions for local problems. In Pilar’s case, the phenomenon of entrepreneurship began as an act of seeking economic solvency and survival through her ingenuity, creativity, and innovation. Similarly, the phenomenon of causation-related bricolage predominates, in which the process of incessant experimentation fost…

Detection of Intrinsic Source Structure at ~3 Schwarzschild Radii with Millimeter-VLBI Observations of SAGITTARIUS A*
2018
We report results from very long baseline interferometric (VLBI) observations of the supermassive black hole in the Galactic center, Sgr A*, at 1.3 mm (230 GHz). The observations were performed in 2013 March using six VLBI stations in Hawaii, California, Arizona, and Chile. Compared to earlier observations, the addition of the APEX telescope in Chile almost doubles the longest baseline length in the array, provides additional {\it uv} coverage in the N-S direction, and leads to a spatial resolution of $\sim$30 $\mu$as ($\sim$3 Schwarzschild radii) for Sgr A*. The source is detected even at the longest baselines with visibility amplitudes of $\sim$4-13% of the total flux density. We argue th…
Surface temperature in the context of FLuorescence EXplorer (FLEX) mission
2007
It has been demonstrated that the spectrum of fluorescence emission is dependent on leaf temperature, thus there is a need for thermal information in order to interpret fluorescence signals. Temperature is also related to transpiration and stomata closure, which affects CO2 uptake and fluorescence. Therefore temperature measurements help to confirm the trends observed in fluorescence measurements. While fluorescence is immediately and uniquely related to photosynthesis, temperature provides additional information about plant status and instantaneous energy/water fluxes between plants and the atmosphere. The objective of this paper is to demonstrate the role of surface temperature in the con…
Multiple-scan voltammetry and OCP: Archaeometric tools for dating archaeological bronzes
2021
[EN] The application of a multiple-scan strategy to nanosamples taken from 18 cross-sections of Bronze Age arms and armour, as well as two Roman coins using two solid-state electrochemical techniques, the voltammetry of immobilized microparticles (VIMP) and open circuit potential measurements (OCP) is described. The voltammetric responses in contact with aqueous acetate buffer can be attributed to the reduction of cuprite with variable degree of compaction and crystallinity revealing significant differences in the gradient of such properties with depth. Such differences are also revealed by "dry" OCP measurements connecting points in the cross section near and separated from the corrosion l…
Una pequeña lámina de plomo con inscripción ibérica de paleografía arcaica del Pico de los Ajos (Yátova, València)
2021
espanolEn este trabajo editamos una pequena lamina de plomo hallada en el Pico de los Ajos (Yatova) en la campana de 2018. La lamina aparecio plegada y contiene una inscripcion iberica de una sola linea en cada cara que muy probablemente configure un solo texto completo. Sus caracteristicas formales son poco comunes, siendo el paralelo mas cercano el de las laminas votivas de El Amarejo. La presencia del elemento kutuŕ, frecuente en las inscripciones votivas rupestres, tambien apuntaria a una interpretacion religiosa. Desde el punto de vista paleografico, cabe senalar que se trata de un texto explicitamente dual, ya que conviven en el las dos variantes de te y ŕ. A pesar de que el contexto …
