Introduction: Splash-form tektites are wholly melted bodies in which the molten primary morphology was principally controlled by cohesive forces, most importantly by surface tension and variably opposed by centrifugal forces from non-uniaxisymmetric rotation. Ultimately the majority of splash-form tektites are plastically deformed by atmospheric interaction during the ejection phase and variabl...

BACKGROUND Purchase of automated systems in today's clinical laboratory needs justification based on demonstrable improvements in efficiency and a sound payback model. Few studies provide information on laboratory automation that focuses on the preanalytical portion of specimen processing. METHODS We recently evaluated an automated preanalytical processing unit (GENESIS FE500) at two academic...

An optimization procedure for designing a ceramic tensile creep specimen to minimize stress concentration is carried out using a finite element method. The effect of pin loading and the specimen geometry are considered in the stress distribution calculations. A growing contact zone between the pin and the specimen has been incorporated into the problem solution scheme as the load is increased t...

The use of acoustic waves in researches related to sea water is of most importance among scientists recently. Since these waves are the only waves, transmitted in water with lowest attenuation and high speed, they can be used in many scientific fields. The main goal of this research is to better understand the physics and mechanisms of sound-seabed interaction, including acoustic penetration, p...

In this paper, the short-term creep behavior of the Inconel-713C superalloy after different pre-treatments including the ageing and forging processes has been studied at 850 °C. The ageing heat treatment was heating at 930 °C for 16 hours without solutioning process. The optical microscopy (OM) and the scanning electron microscopy (SEM) techniques were applied for microstructural evaluations. T...

the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

OBJECTIVES To evaluate the intra- and postoperative outcomes of patients undergoing laparoscopic radical nephrectomy with intact specimen extraction through a Pfannenstiel transverse suprapubic incision. METHODS Prospective follow-up of 26 laparoscopic transperitoneal radical nephrectomies for suspected renal tumors in which the kidneys were extracted via a Pfannenstiel lower abdominal transv...
