Time-dependent creep analysis is crucial for the performance and reliability of piezoactuators used for high-precision positioning and load-bearing applications. In this study history of stresses, deformations and electric potential of hollow rotating cylinders made of functionally graded piezoelectric material (FGPM), e.g., PZT_7A have been investigated using Mendelson’s method of successive e...

To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...

The use cu electro-convulsive therapy has established itself in psychiatric practice. Opinion varies considerably about the risk of fractured limbs and spines. Accidental electric shocks have caused severe injuries to the spine and limbs, but with electro-convulsive therapy the passage of the current is briefer, the voltage is lower, the amperage is less and the size of the terminals is smaller...

OBJECTIVE The term 'total laparoscopic hysterectomy (TLH) with classical suture method' refers to a surgical procedure performed using only sutures and ligations with intracorporeal or extracorporeal ties, without using any laser or electronic cauterization devices during laparoscopic surgery as in total abdominal hysterectomy. However, the method is not as widely used as electric coagulation e...

electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. electric motors account for between 43 and 46% of all global electricity consumption approximately. they give rise to about 6 040 mt of co2 emissions. end‐users approximately spend usd 565 billion per year on electricity [1]. in recent years, increase in e...

using an electric differential (ed) in electric vehicle has many advantages such as flexibility and direct torque control of the wheels during cornering and risky maneuvers. despite its reported successes and advantages, the ed has several problems limits its applicability, for instance, an increment of control loops and an increase of computational effort. in this paper, an electric differenti...

Philip K. Stoddard Department of Biological Sciences Florida International University Miami, Florida, 33199, USA Synopsis Electric sense (i.e. the ability to detect low-voltage electrical impulses from other individuals) is found in most primitive fish orders, a few derived teleost fish, some aquatic amphibians, the platypus and the echidna. Electric signals (i.e. self-generated electrical sign...

BACKGROUND Damaged metal halide lamps are known to cause outbreaks of photokeratitis and UV-radiation burns among children and adults, which has prompted the Food and Drug Administration, Rockville, Md, to publish consumer recommendations to prevent such injuries. We investigated 3 outbreaks of photokeratitis and UV-radiation burns in gymnasiums associated with failure to heed these recommendat...

background traumatic brain injury (tbi) is an important public health problem throughout the world. objectives the aim of this study was to assess repeated glasgow coma scale (gcs) scores in predicting the severity of tbi and patients’ survival. patients and methods in this longitudinal study used a total sample of 239 patients, all of whom were hospitalized with traumatic brain injuries. subje...

introduction: public and occupational exposure to extremely low frequency (elf) electric and magnetic fields induced by electrical equipment is a significant issue in the environment and at the workplace due to their potential health effects on public health. the purpose of this study was assessment of the electric and magnetic fields intensities and determination of mental and psychological ef...
