13. The Rarity of Penetrating Ulcer with Intramural Hematoma of the Ascending Aorta
ABSTRACT We report a case of a 58-year-old man with multiple symptomatic penetrating atherosclerotic ulcers and concomitant intramural hematoma of the ascending aorta. The patient was successfully treated using a 24-mm Gelweave graft in the ascending aorta. He was discharged four days post operation and remains asymptomatic 14 months postoperatively. This ca

14. Evaluation of Surgical Outcomes of Type A Intramural Hematoma
Abstract Introduction: In this study, we aimed to retrospectively evaluate the results of type A intramural hematoma (TA-IMH) cases that underwent ascending aortic surgery. Methods: One hundred ninety-four patients who underwent aortic surgery between 2010 and 2018 were included in this study. TA-IMH was differentiated according to tomography angiographic

15. Surgical Removal of The Mechanical Valve Leaflet Dislocated into The Pulmonary Vein
ABSTRACT Accidental detachment of mechanical valve leaflet during implantation is a rare and potentially serious complication. When the lost leaflet cannot be found by direct visualisation, additional diagnostic procedures are necessary to detect it. Computer tomography is the best detection method, but the patient needs reoperation. We presented a patient i

18. Frequency Reconfigurable Near-Zero Refractive Index Material for Antenna Gain Enhancement Applications
Abstract In this paper, a planar near-zero refractive index material (NZRIM) consisting of an outer loop with four symmetrical quarter-rings is proposed. The quarter-rings are connected to the outer loop by two symmetrical microstrip lines on the opposite side. The backside of the substrate has mutually central split microstrip lines. By loading adjustable c

19. MIMO-PLC Communications in an Experimental Medium Voltage Network: Measurement and Analysis
Abstract This paper presents measurements at a mock-up medium voltage network to verify the feasibility of Broadband Power Line Communication (BPLC). We use the data extracted within the frequency range 2 − 30 MHz to characterize a MIMO PLC network using different phase combinations, defining the best and worst use case scenarios. The empirical data shows

20. Equipment for Monitoring Synchronous Generators Condition through External Magnetic Field Waveforms
Abstract This paper presents an equipment for monitoring synchronous generators condition through characteristics of the time derivative of the external magnetic field. The developed monitoring methodology allows the identification of established or incipient faults, by detecting changes in the magnetic signature of the synchronous generator. In this methodo

21. Surgical outcomes between two endoscopic approaches for maxillary cysts
Abstract Objective: To compare recurrence rates and symptomatic relief in symptomatic maxillary sinus Retention Cysts (RCs) between Middle Meatus Antrostomy (MMA) alone and Inferior Meatus Antrostomy (IMA) with basal mucosa electrocoagulation. Methods: Patients with symptomatic unilateral maxillary RCs were randomly allocated to MMA (n = 54) and IMA combin

22. How do CO2 and radon gases affect groundwater mining in the Canary Islands?
Abstract Water galleries are mines that seek to supply drinkable and irrigation water from the aquifer, in order to meet the demand for water in the Canary Islands. This sort of work entails a series of health risks in the form of gases. This document compiles three different studies on the gases that can be found in water galleries in the Canary Islands, ha

23. Propensity-Matched Analysis of Del Nido Cardioplegia in Adults Undergoing Cardiac Surgery with Prolonged Cross-Clamping Time
Abstract Introduction: There is not enough data in the literature regarding the safety and efficiency of del Nido cardioplegia in patients with prolonged cross-clamping time. This study aims to determine the efficacy and safety of del Nido cardioplegia compared to cold blood cardioplegia in patients with prolonged aortic cross-clamping time. Methods: In th

24. Tepid Modified Del Nido Cardioplegia in Adults Undergoing Cardiac Surgery: A Propensity-Matched Analysis
Abstract Introduction: Del Nido cardioplegia was reported to provide adequate myocardial protection and clinical outcomes with improved surgical flow in adult cardiac surgical procedures. And many clinicians have already modified the traditional formula. This study aims to investigate the efficacy and safety of tepid modified del Nido cardioplegia compared
