SINONASAL KERATINIZING SQUAMOUS CELL CARCINOMA: CLINICAL AND MAGNETIC RESONANCE IMAGING FINDINGS

Sinonasal keratinizing squamous cell carcinoma is a rare malignancy originating from the paranasal sinuses and nasal cavity epithelium. This report details the clinical presentation, radiological insights, and management of a localized sinonasal keratinizing squamous cell carcinoma case in the maxillary sinus. A 47-year-old female patient with asymptomatic cheek swelling underwent comprehensive evaluation. Clinical examination, orthopantomography, conebeam computed tomography, and magnetic re...

Mathematical Model for Sizing and Optimizing a Test Bench for Electric Motors of Electric Vehicles

A mathematical model has been formulated to optimize the setup of an end-of-production-line (EOL) test bench that is used to evaluate the efficiency of electric motors or axles designed for electric vehicles. The model can forecast the performance of EOL testing benches and electric motors/axles under a variety of conditions, thereby eliminating the need for extensive physical trials and minimizing the associated energy usage. The proposed model can be adjusted to handle different power ratin...

Experimental Assessment of Environmental and Economic Impacts of Dampers’ and Filters’ Faults in a Typical Air-Handling Unit in Southern Italy

Heating, Ventilation and Air-Conditioning (HVAC) systems are responsible of 50-60% of energy demand of the building sector. The scientific literature highlights that HVAC units are frequently operated under faulty conditions that can significantly affect their performance. In this paper, the performance of a typical single-duct dual-fan constant air volume Air-Handling Unit (AHU) is investigated through a number of experiments performed during Italian cooling and heating seasons under both fa...
