Roughness analysis on composite materials (Microfilled, nanofilled and silorane) after different finishing and polishing procedures

The finishing and polishing of composite materials affect the restoration lifespan. The market shows a variety of finishing and polishing procedures and the choice among them is conditioned by different factors such as the resulting surface roughness. In the present study, 156 samples were realized with three composite materials,-microfilled, nanofilled and silorane-, and treated with different finishing and polishing procedures. Profilometric analyses were carried out on the samples’ surface, the measured roughness values were submitted to statistical analysis. A complete factorial plan was drawn up and two-way analysis of variance (ANOVA) was carried out to investigate whether the following factors affect the values of roughness: (i) material; (ii) polishing/finishing procedure. Tukey post-hoc test was also conducted to evaluate any statistically significant differences between the material/procedure combinations. The results show that the tested materials do not affect the resulting surface quality but roughness values depend on the finishing/polishing procedure adopted. The procedures that involve: (a) the finishing with medium Sof-Lex discs and (b) the finishing with two tungsten carbide multi-blade milling cutters Q series and UF series are those that allow the lowest values of roughness to be obtained

Exploring the Interplay between Facial Expression Recognition and Emotional Intelligence in Adults: Implications for Novel Learning Methods

Background: Considering the widespread use of personal protective equipment (PPE) during the COVID-19 pandemic, which conceals facial expressions, this study aims (1) to explore facial expression recognition ability; (2) to assess the ability to read facial expressions under different conditions of face coverage; and (3) to investigate the role of emotional intelligence in facial expression recognition. This multidimensional exploration provides vital insights for creating novel learning methods, emphasizing the pivotal role of emotions. Methods: The study sample comprised 124 Italian adult subjects, consisting of 71 females (57.3%) and 53 males (42.7%), with a mean age of 35.31 years. The present investigation employed the Emotional Intelligence Scale (EIS) and an image-based questionnaire administered via the online platform Google Forms. Student’s t-test and one-way ANOVA were computed with SPSS (v. 29). Results: Significant differences were found based on gender, profession, and level of education in face expression recognition and emotional intelligence. The implications for learning processes are discussed. Conclusion: This study unveils the intricate dynamics of emotion recognition, gender, occupation, level of education’s influence, and emotional intelligence. By incorporating these insights into educational programs, a transformative process can be initiated, nurturing not only empathy, cultural insight, and emotional intelligence but also catalyzing the evolution toward inclusive and emotionally equipped societies

Dataset Fluorishing

The COVID-19 pandemic has significantly impacted adolescents, a vulnerable group undergoing critical developmental changes. This study aims to explore and compare how flourishing, perceived social support, empathic selfefficacy changes in adolescents during the lockdown and in the present. A sample of 261 Italian adolescents (79.3% females, 20.7% males, aged 13-19) has been enrolled. Flourishing Scale (FS), Perceived Empathic Self-Efficacy Scale (AEP/A), and Multidimensional Scale for Perceived Social Support (MSPSS) were employed. Results indicated a significant decrease in well-being during lockdown, with flourishing, empathic selfefficacy, and social support showing improvement post-lockdown. Gender differences revealed males reporting higher flourishing and friend support during lockdown. Younger adolescents exhibited higher flourishing during lockdown. High-flourishing individuals reported better outcomes in all variables. A moderation analysis indicated that empathic self-efficacy moderated the relationship between flourishing and social support post-lockdown. Findings emphasize the need for targeted interventions, including learning strategies to enhance empathic self-efficacy, potentially improving overall well-being for adolescents in postpandemic phases. Further research is crucial to validate and expand upon these insights.</p

Schooling and Occupational Outcomes in Adults with ADHD: Predictors of Success and Support Strategies for Effective Learning

Attention Deficit Hyperactivity Disorder (ADHD) is a neurobehavioral disorder that is usually diagnosed in childhood. It is characterized by attention deficits, hyperactivity, and impulsivity leading to significant impairment in academic, occupational, familiar, and social functioning. Most of the literature has been focusing on the impact of this condition on infancy and preadolescence, but little is known on its consequences in adulthood. This narrative review addresses this gap by focusing on the studies regarding the schooling outcomes of this population. After identifying the specific clinical and neuropsychological profile of ADHD in adults, this study analyzes their precise needs for effective learning and presents evidence on their academic and occupational achievements. Pharmacological, educational, and rehabilitative factors predicting a positive scholastic and career success are critically reviewed. Finally, this study focuses on the strategies that can improve the learning processes in adults with ADHD by expanding the analysis on executive functions, metacognition, and emotional dysregulation. Schooling outcomes in adults with ADHD, therefore, are conceptualized as a complex measure depending on several variables, like early pharmacological treatment, educational support, neuropsychological intervention, and targeted strategies for life-long learning

Design and characterization of a dual modality (SPET-US) tomographic device

In the last few years, integrated dual-imaging systems have emerged as a new modality for cancer staging with the aim to offer both functional and anatomic information. At moment the prevalent dual modality devices are based on Computer Tomography and Positron Emission Tomography. In this sense, the scientific community is debating about the high effective dose to the patient, representing an indicator of the stochastic risk, especially from Computer Tomography examination. So, a new dual modality imager, based on a Ultrasound probe and a Single Photon Emission Tomography was made in order to combine functional information, from gamma camera with structural one, obtained from the Ultrasound equipment. The Ultrasound probe is the most diffuse anatomical examination device at zero-dose, using a cost-effective and reliable method with few restriction in use. The proposed Single Photon Emission Tomography detector is a compact gamma camera (10x10 cm(2) active area), based on LaBr3:Ce scintillation crystal coupled to 4x4 array of Hamamatsu HS500-CMODS Multi Anode Photomultiplier, with high spatial and energy resolution performances, equipped with rotating slanthole collimator. A calibration phantom, made of a Co-57 point source inside a water filled box, was utilized to acquire 3D dual modality images. The detector has shown good performances in terms of spatial resolution and localization along z-axis of object of interest. This project was developed by several Italian Universities under an INFN collaboration

DoI position resolution in a continuous LaBr3(Ce) scintillation crystal for gamma-ray imaging

A Monte Carlo simulation of a 50mm 750mm 74mm continuous crystal has been developed to investigate the correlation between the scintillation light width (\u3c3) and the Depth of Interaction (DoI) within the crystal. Our studies are based on a LaBr3(Ce) crystal, in order to take advantage of its high light yield to reduce the statistic uncertainties on the estimators of the \u3c3. The first one, the standard deviation of the light distribution, has demonstrated a poor, though linear, correlation to DoI, that is not experimentally detectable. Otherwise, the second estimator,N/I, is the ratio of the total number of photoelectrons to the maximum number of photoelectrons collected from a single anode, in a scintillation event. N/I has been found to have the best correlation to DoI, that provides 2 mm resolution

Dual Modality Ultrasound-SPET Detector for Molecular Imaging

We present an innovative compact dual-modality detector, which integrates an ultrasound probe with a scintigrafic γ-camera for molecular imaging in medicine, in order to get both morphological and functional information in a single three-dimensional image. The scintigraphic detector consists of a 2×2 array of a multi-anode PMT Hamamatsu H8500-Mod8 and a 4.0 mm thick continuous LaBr3(Ce) crystal equipped with four segment slant-hole collimators for single photon imaging (SPET). The collimator permits to recover the depth of a lesion by rotating around its vertical axis (z) without the need of rotating the camera around the investigated object. This detector can take advantage from being positioned close to the object and overcome the intrinsic limitations in spatial resolution arising from the geometry of SPET/CT gantry. The aim of this work is to describe preliminary phantom analysis and to provide a 3D US/SPET image. © 2011 Elsevier B.V
