Electro-acupuncture is a burgeoning treatment using the needle inserting into the body acupoints and the low-frequency pulse current being electrified by an electric acupuncture machine. This study was designed to evaluate the effects of preconditioning of electro-acupuncture on postoperative cognitive dysfunction in elderly.Ninety patients scheduled spine surgery were randomly assigned into 2 ...

Preliminary note The aim of the investigation was to compare and unveil efficiency of electro-hydraulic control (EHR) system to mechanical three point hitch regulation in mouldboard ploughing. Increase of working velocity and three point hitch automatic regulation activity decreased depth of ploughing at both regulation systems but electro-hydraulic system done it more accurately since deviatio...

The expression of the anti-apoptotic molecules Bcl-2 and transforming growth factor-beta 1 is known to confer protective effects on the cerebral ischemia-reperfusion injury. The current study investigated the expression levels of Bcl-2 and transforming growth factor-beta 1 in response to multiple pre-ischemia electro-acupuncture at acupoints Zusanli (ST36) and Fengchi (GB20) stimulation. Rats w...

The physical mechanisms responsible for the electrical orientation and electrical rotation of metal nanowires suspended in an electrolyte as a function of frequency of the applied ac electric field are examined theoretically and experimentally. The alignment of a nanowire in an ac field with a fixed direction is called electro-orientation. The induced constant rotation of a nanowire in a rotati...

The restless legs syndrome (RLS) is a common sensorimotor condition that often results in discomfort and sleep disturbance. Diagnosis of RLS is entirely clinical and based upon a patient's description of subjective symptoms, and thus when considering RLS diagnosis non-specificity is a real problem. RLS is associated with periodic limb movements during sleep (PLMS) in up to 90% of RLS sufferers;...

As oil fields age, artificial lift systems are required to maintain production levels when reservoir pressures get too low. Failure of an ESP in a well can stop production or even lead to a dangerous event. ESPs are fitted with downhole monitoring units that transmit streams of data back to the surface including: motor temperature, pump intake pressure, intake temperature motor vibration, and m...

The paper introduces an electro-mechanical transducer finite element (EMT) for the strongly coupled simulation of micro electro-mechanical system (MEMS) devices in the commercial finite element analysis (FEA) package ANSYS.
