The sequence …

Residents’corner August 2014. sQUIZ your knowledge!: Persistent papules on the lateral aspects of both palms

2014

A 52 year-old woman, with no relevant past medical history, presented with asymptomatic cutaneous lesions (that had first been noticed fifteen years before). On examination, several 2-3 mm reddish-yellow, well-defined and firm papules were noted on the lateral aspects of both hands (figure 1).What is your diagnosis (figure 1)? The answer is on the next page.The answer to sQuiz: AcrokeratoelastoidosisA biopsy of one of the lesions showed orthokeratotic hyperkeratosis with a central area bearing a [...]

Modificazioni posturali indotte dal canottaggio in giovani atleti ben allenati

2005

This research brings evidence that rowing represents a valid sports model for helping both healthy and paramorphic people in changing unhealthy back positions. In particular, this study analyzed the changes induced to the back of twenty well trained athletes. Furthermore, it was taken into consideration a case of an athlete who presented a case of kyphosis and lordosys. This study was carried on for a period of two years during which it was observed that both kyphosis and lordosys had disappeared in the subject observed for this study. The quantitative and qualitative variables taken into account here, demonstrate that the positive results for correcting and self-correcting the position of …

Sustainable Supercapacitors Based on Polypyrrole-Doped Activated Biochar from Wood Waste Electrodes

2023

The synthesis of high-performance carbon-based materials from biomass residues for electrodes has been considered a challenge to achieve in supercapacitor-based production. In this work, activated biochar has been prepared as the active electrode material for supercapacitors (SCs), and an effective method has been explored to boost its capacitive performance by employing polypyrrole (PPy) as a biochar dopant. The results for physicochemical characterization data have demonstrated that PPy doping affects the biochar morphology, specific surface area, pore structure, and incorporation of surface functionalities on modified biochar. Biochar-PPy exhibited a surface area of 87 m2 g−1, while pris…
