Abstract Ultrasonic scanning of large spiral bevel gears and the subsequent fracture analyses early-stage tooth flank fractures imply a mode II crack initiation under surface-parallel, orthogonal shear stresses. An iteration Dang Van criterion is presented that focuses exclusively on surface-parallel material planes, yielding standardizable approach for study in gears. It shown Van’s stress amp...

Volcano ground deformation is a tricky puzzle in which different phenomena contribute to the surface displacements with spatial–temporal patterns. We documented some high variable patterns response volcanic and seismic activities occurring at Mt. Etna through January 2015–March 2021 period by exploiting an extensive dataset of GNSS InSAR observations. The most spectacular pattern superfast seaw...

Solar wind/magnetosheath plasma in the magnetosphere can be identified using a component that has a higher charge state, lower density and, at least soon after their entry into the magnetosphere, lower energy than plasma from a terrestrial source. We survey here observations taken over 3 years of He2+ ions made by the Magnetospheric Ion Composition Sensor (MICS) of the Charge and Mass Magnetosp...

OBJECTIVE Many emergency physicians (EPs) order "confirmatory" abdominal computed tomography (CT) in young flank pain patients, despite a high clinical suspicion of renal colic and the risk of radiation exposure. We measured the adverse outcome rate among flank pain patients identified as not requiring abdominal CT by the EP on a data form, regardless of whether CT was eventually ordered. Our s...

A 56-year-old woman was referred by her family (150/100 mmHg). The family history was positive for hypertension and blood pressure was perfectly condoctor to our outpatient hypertension clinic for further evaluation of hypertension and a small left kidney. trolled (120/70 mmHg) with an ACE-inhibitor. Because of the pain in the left flank, 3 weeks The patient was referred with the suggestion tha...

OBJECTIVES Percutaneous nephrolithotomy (PCNL) is the standard management for large and/or complex urolithiasis, but the standard patient position for PCNL is undecided. With the patient prone PCNL has several drawbacks, while when supine, as described previously, PCNL has mechanical limitations. We describe a modification that aims to overcome these limitations and provide easy access comparab...

This paper reports the successful pregnancy in rats with only 10-20% of ovarian tissue. Sprague-Dawley female rats of breeding age were divided into five groups: group 1 (completely ovariectomized), the ovaries from both the sides of the rats were removed completely; group 2 (partially ovariectomized, 80-90% of the ovary of each side was removed leaving the remaining tissue in place; group 3 (o...

OBJECTIVE We evaluated the effect of terazosin in the improvement of lower urinary tract symptoms and flank pain in patients with internal ureteral stents. METHODS In this double-blind randomized clinical trial, 73 patients with unilateral ureteral stone and hydroureteronephrosis who underwent insertion of an internal ureteral stent after transureteral lithotripsy (TUL) were randomized into t...
