1. DESIGN AND EXPERIMENT OF SELF-PROPELLED SYSTEM FOR PADDY FIELD WEEDER BASED ON THE INTERACTION MECHANISM OF WHEEL-SOIL
ABSTRACT Aiming at the low mechanization of paddy field weeding and lack of dedicated agricultural machinery for paddy field weeding in China, a self-propelled system of paddy field weeding machine was designed. The overall structure and working principle of self-propelled system were illustrated and analyzed. The interaction mechanism of wheel-soil during w

2. Laser Lead Extraction During Venoarterial ECMO support
Abstract The treatment of valvular endocarditis in patients with cardiac implantable electrophysiological device (CIED) includes valvular surgery and lead extraction. This can be challenging in patients with severely reduced left ventricular ejection fraction (LVEF). Reduced LVEF in combination with sepsis and cardioplegic cardiac arrest can make weaning fro

3. ENERGY EFFICIENCY OF AGRICULTURAL TRACTORS EQUIPPED WITH CONTINUOUSLY VARIABLE AND FULL POWERSHIFT TRANSMISSION SYSTEMS
ABSTRACT The efficiency of agricultural tractor transmission has been improved over the years, with new concepts such as Continuously Variable Transmission (CVT) and Full Powershift (FPS) evolving in advanced technologies. Both options seek to offer the farmer greater operational results with lower energy expenditure, necessitating studies to assess the effe

4. Agricultural tractor performance fueled with proportions of biodiesel
ABSTRACT Among the fuel sources used nowadays, biofuels stand out for being renewable and biodegradable. In this sense, this work aimed to evaluate the performance and smoke opacity of an agricultural tractor in soil tillage activities, depending on the biodiesel blends and the engine rotation. Were used six blends of soy (S) and murumuru (M) biodiesel and s

6. Nerve-sparing robotic-assisted radical prostatectomy: how I do it after 15.000 cases
ABSTRACT Introduction: Over the years, since Binder and Kramer described the first Robotic-assisted Radical Prostatectomy (RARP) in 2000, different Nerve-sparing (NS) techniques have been proposed by several authors (1). However, even with the robotic surgery advantages, functional outcomes following RARP, especially erection recovery, still challenge surge

7. Robotic management of congenital urethra-vaginal fistula with transverse vaginal septum
ABSTRACT Introduction: The transverse vaginal septum (TVS) with congenital urethra-vaginal fistula (CUVF) is a rare anomaly of the mullerian duct (1, 2). Incomplete channelling of the vaginal plate, or an abnormality in the fusion of the vaginal component of mullerian duct with the urogenital sinus results in TVS (1, 3, 4). High CUVF occurs due to the persi

8. Percutaneous and endoscopic combined treatment of bladder and renal lithiasis in mitrofanoff conduit
ABSTRACT Introduction and Objectives: Treatment of bulky lithiasis in continent and non-continent urine storage reservoirs has been widely described and debated (1). Less is known about the optimal treatment in patients with a Mitrofanoff conduit. If voiding in these patients is incomplete, leading to recurrent symptomatic bacteriuria, formation of large li
