Influence of enhancement filters in apical bone loss measurement: A cone-beam computed tomography study
2016
Background The use of cone-beam computed tomography images (CBCT) providing a better assessment of bone injuries, although the sensibility of lesions measurement might be improved by the use of enhancement filters. Objective: This study aimed to analyze the influence of enhancement filters in apical bone loss measurement. Material and Methods Eighteen CBCT cases randomly selected of apical bone loss were evaluated. The analyses were carried out following the evaluation in axial, coronal and sagittal protocols, using enhancement filters as Hard, Normal, and Very Sharp. The variables were statistically analyzed by Friedman and Wilcoxon test, Spearman’s rho, and intraclass correlation coeffici…
Direct Instruction vs. Cooperative Learning in Physical Education: Effects on Student Learning, Behaviors, and Subjective Experience
2020
(1) Background: The objective was to analyze if cooperative learning (CL) can have benefits compared to direct instruction (DI) in learning, behavior, and subjective experience of pupils. (2) Methods: An intervention was performed with a counterbalanced within-subjects design. To perform the intervention, 75 schoolchildren aged 10 to 12 from four primary classes were divided into two groups, and two units were taught in each one, namely &ldquo
Evaluation of intraocular pressure and other biomechanical parameters to distinguish between subclinical keratoconus and healthy corneas
2021
(1) Purpose: To assess the main corneal response differences between normal and subclinical keratoconus (SCKC) with a Corvis® ST device. (2) Material and Methods: We selected 183 eyes of normal patients, of a mean age of 33 ± 9 years and 16 eyes of patients with SCKC of a similar mean age. We measured best corrected visual acuity (BCVA) and corneal topography with a Pentacam HD device to select the SCKC group. Biomechanical measurements were performed using the Corvis® ST device. We carried out a non-parametric analysis of the data with SPSS software (Wilcoxon signed rank-test). (3) Results: We found statistically significant differences between the control and SCKC groups in some corneal b…
Evaluation of the qualitative properties and consumer perception of marinated sardine Sardina pilchardus: The effect of fucoxanthin addition
2023
With the increasing consumer awareness and demand for healthy food and natural ingredients; there is an urgent need to develop and propose innovative products to industry. In this study, the combined effect of various time of pre-incubation (30, 60 and 90 min) in vinegar and the addition of fucoxanthin (Fux) extracted from the brown alga Dictyopteris polypodiodes to the covering oil of sardine fillets was investigated during 3 months of refrigerated storage at 4◦C. Compared to fresh sardines, biogenic amines (Bas) decreased significantly in all marinated lots (histamine <0.07 mg/100 g, cadaverine <0.0 mg/100 g) and remained far below the regulatory limit up to the end of storage indic…
DACRON© 360 WOVEN: EXPERIMENTAL CHARACTERIZATION AND COMPUTATIONAL ASPECTS
2010
In this paper a first experimental study on Dacron© 360 woven constitutive behavior is presented. This woven is widely adopted in sail manufacturing, it is obtained by weaving polyethylene terephthalate (PET) yarn and it shows some peculiar features due to its own manufacturing process. The experimental tests, in terms of tensile tests and cyclic tests, clearly show the orthotropy features of the material, its high strength and deformability. The examination with optical microscope of the tested specimen allows to evidence the interaction between warp and weft yarns. The obtained results represent a first step for the definition of a correct computational approach to such materials.
A Unifying Framework for Perturbative Exponential Factorizations
2021
We propose a framework where Fer and Wilcox expansions for the solution of differential equations are derived from two particular choices for the initial transformation that seeds the product expansion. In this scheme, intermediate expansions can also be envisaged. Recurrence formulas are developed. A new lower bound for the convergence of theWilcox expansion is provided, as well as some applications of the results. In particular, two examples are worked out up to a high order of approximation to illustrate the behavior of the Wilcox expansion.

Lumevis ™: a new medical device to prepare patients for esophagogastroduodenoscopy. Experimental clinical study.
2020
Esophagogastroduodenoscopy (EGDS) is the gold standard exam for upper gastrointestinal diseases. EGDS is very important in Early Gastric Cancer diagnosis and treatment but it is an operator-dependent exam and there are lots of factors that reduce its visibility (mucus, bubbles and foam).The aim of our study is to evaluate if the use of Lumevis™ improves mucosa visualization during EGDS without increasing the examination time and complications' rate and comparing the differences in patients prepared with water or no intervention.we recruited 50 patients from 01/08/2020 to 31/08/2020 who came to our observation for epigastric pain, dyspepsia and gastroesophageal reflux (GERD). For each patien…
Heterogeneidad en el impacto de la política de becas en la escolaridad secundaria postobligatoria en España: un análisis por subgrupos poblacionales
2013
El presente trabajo analiza el impacto de las becas sobre la probabilidad de finalizar con éxito el nivel secundario postobligatorio en España en el caso de diferentes subgrupos poblacionales. Se aplica un diseño cuasiexperimental (Propensity score matching) a partir de la Encuesta de Condiciones de Vida (ECV-2006). Los resultados confirman la existencia de efectos diferenciales positivos (con relación al impacto medio) de la política educativa en el caso de las mujeres y de los alumnos provenientes de hogares desfavorecidos, demostrando la existencia de heterogeneidad en el impacto de la política analizada.
Mācīšanās rezultātu nozīme profesionālās vidējās izglītības vadībā
2014
ANOTĀCIJA Promocijas darba „Mācīšanās rezultātu nozīme profesionālās vidējās izglītības vadībā” mērķis ir izpētīt mācīšanās rezultātu nozīmi profesionālajā vidējā izglītībā un noskaidrot, kā notiek pāreja uz mācīšanās rezultātos balstītu izglītības procesu. Pētījuma ietvaros tika veikta profesionālās izglītības iestāžu audzēkņu aptauja, skolotāju un darba devēju intervijas. Pētījumā secināts, ka skolotāji un darba devēji neizprot mācīšanās rezultātu lomu profesionālajā izglītībā. Skaidri formulēti mācīšanās rezultāti profesionālās izglītības programmās sniedz precīzu informāciju par mācību procesu un tā iznākumu visām iesaistītajām pusēm, līdz ar to vairāk jauniešu var izvēlēties profesionā…
