1. The Impact of Transcatheter Aortic Valve Implantation (TAVI) on Serum Apelin Levels in Patients with Aortic Valvular Stenosis
Abstract Introduction: In this study, we aimed to investigate the impact of transcatheter aortic valve implantation (TAVI) on serum apelin levels in patients with severe symptomatic aortic valve stenosis (AS). Methods: Forty-six consecutive patients (76.9±7.4 years, n=27 women) who underwent TAVI and 45 age- and sex-matched control subjects were included

3. DEVELOPMENT OF A PNEUMATIC OLIVE HARVESTER
ABSTRACT A pneumatic olive harvester was developed and evaluated in this study. The components of the developed machine were the limb clamp, vibrating unit, control elements, main tube, air-pressured hoses, control valve, and power source. The measurements that related to the development of the harvester were fruit and limb damage, and some physical and mech

6. Aortic Valve Replacement Via Right Anterior Mini-Thoracotomy: the Conventional Procedure Performed Through a Smaller Incision
Abstract Minimally invasive aortic valve replacement has gained consent due to its good results in terms of minimized surgical trauma, faster rehabilitation, pain control and patient compliance. In our experience, we have tried to replicate the conventional and gold standard approach through a smaller incision. Sparing the right internal thoracic artery, avo

10. Dimensional design of the barometric leg of a flotation column: a key to operational stability
Abstract The inefficiency in controlling the slurry/froth interface level of a scavenger column flotation stage was severely impairing the process performance of an iron mining company, increasing the iron content in the tailings to levels above 20% and, consequently, not meeting the company's iron recovery and pellet feed production targets. Based on mass b

12. Numerical study of upstream disturbances on the performance of electromagnetic and ultrasonic flowmeters
ABSTRACT Electromagnetic and ultrasonic flowmeters are high precision devices that can measure the water flow in pressurized irrigation networks. In these networks, the inadequate installation distance of flow control valves generates upstream disturbances which will increase measurement errors and reduce the accuracy of the equipment. Therefore, estimating
