Italian Normative Data for the Original Version of the Tower of London Test: A Bivariate Analysis on Speed and Accuracy Scores
No full textThe Tower of London (ToL) test is traditionally used to assess strategical reasoning, problem-solving, and mental planning in clinical populations. Here, we provide the Italian standardization norms for the original, 12-problem version of the ToL test. The performance of 216 Italian individuals ranging 18 to 89 in age was scored in terms of both Time (Speed) and Accuracy—the time, and the number of attempts, necessary to find a solution. We performed univariate analyses on separate Time and Accuracy scores, using Age in years, Education in years, and Sex (male vs. female) as predictors. z scores and equivalent scores were provided. Moreover, we performed a bivariate analysis for the assessment of individuals’ performance in terms of Time and Accuracy simultaneously. This standardization allows clinicians to use the original, most widespread version of ToL with the Italian population, thus optimizing comparability with other clinical and experimental research worldwide. Critically, this article offers a new statistical perspective on how Time and Accuracy scores, which are typically related to each other, can be combined to obtain a single, consistent clinical categorization that captures most of the information contained in the patient’s performance
Compression Behavior of 3D Printed Composite Isogrid Structures
No full textComposite materials, particularly carbon fiber-reinforced polymers (CFRPs), have become a cornerstone in industries requiring high-performance materials due to their exceptional mechanical properties, such as high strength-to-weight ratios, and their inherent lightweight nature. These attributes make CFRPs highly desirable in aerospace, automotive, and other advanced engineering applications. However, the compressive behavior of CFRP structures remains a challenge, primarily due to the material sensitivity to structural instability, leading to matrix cracking and premature failure under compressive loads. Isogrid structures, characterized by their unique geometric patterns, have shown promise in enhancing the compressive behavior of CFRP panels by providing additional support that mitigates these issues. Traditionally, these structures are manufactured using automated techniques like automated fiber placement (AFP) and automated tape laying (ATL), which, despite their efficacy, are often cost-prohibitive for small-scale or custom applications. Recent advancements in 3D-printing technology, particularly those involving continuous fiber reinforcement, present a cost-effective and flexible alternative for producing complex CFRP structures. This study investigates the compressive behavior of 3D-printed isogrid structures, fabricated using continuous carbon fiber reinforcement via an Anisoprint Composer A3 printer equipped with towpreg coextrusion technology. A total of eight isogrid panels with varying infill percentages were produced and subjected to buckling tests to assess their performance. The experimental results indicate a direct correlation between infill density and buckling resistance, with higher infill densities leading to increased buckling loads. Additionally, the failure modes were observed to shift from local to global buckling as the infill density increased, suggesting a more uniform distribution of compressive stresses. Post-test analyses using optical microscopy and scanning electron microscopy (SEM) revealed the presence of voids within the 3D-printed structures, which were found to negatively impact the mechanical performance of the isogrid panels. The findings of this study demonstrate that 3D-printed isogrid CFRP structures can achieve significant buckling resistance, making them a viable option for high performance applications. However, the presence of voids remains a critical issue, highlighting the need for process optimizations in 3D-printing techniques to enhance the overall performance and reliability of these structures
Forming behaviour of friction stir lap welded joints
No full textFriction stir lap welding was performed on two and on three sheets in aluminium alloy, respectively. The effect of the stacking mode of the sheets with different thicknesses and that of the tool probe geometry were analyzed at given rotational and welding velocities. The welding results were studied in the weld joint section perpendicularly to the welding velocity direction.
It resulted that, in the case of the stack of three sheets, the thinnest blank has to be positioned in the middle, in order to get a sound weld. In the two sheet stacking, the thinnest blank must be placed below the thickest one. The subsequent upsetting of the lap joint at different temperatures produced an homogeneous microstructure even when the thick tool was used for the friction stir welding. It was observed that low upsetting load values, related to low friction amounts, could determine improved homogenization in terms of microstructure and deformation levels
Aldo Francesco Massèra e i manoscritti di poesia medievale
No full textNel saggio si esaminano le principali edizioni di testi poetici medievali allestite da Aldo Francesco Massèra nel corso della sua lunga attività di editore, concentrandosi in particolare sulle metodologie utilizzate, dato che lo studioso romagnolo si trovò ad operare in anni decisivi per lo sviluppo di un'ecdotica dei testi volgari in Italia. Questa prospettiva permette di seguire i rapporti di Aldo Francesco Massera col più grande filologo della sua generazione, Michele Barbi, con cui lo studioso romagnolo entrò in contatto molto presto ed ebbe un confronto continuo e fecondo, a dispetto delle significative differenze d'impostazione metodologic
