In this review paper, an overview is given of two emerging research topics that address the importance of long-range physical signaling in living biosystems. The first topic concerns the biophysical principles and the physiological significance of long-range cell-to-cell signaling through electrical signals facilitated by membrane nanotubes (MNTs) (also called "tunneling nanotubes"), namely lon...

cross linking of high density polyethylene (hdpe) was first performed via high energy10 mev electron beam (eb) irradiation. hdpe was also cross linked withdicumyle peroxide (dcp).the gel content of samples was determined by solvent extraction.degree of cross linking was evaluated by hot set apparatus; as well .in order to clarify the effectof nature of cross linking, correlation of electrical p...

copper–silver bimetallic strips were produced by cold roll welding process and were treated by diffusion annealing in the temperature range 250–800 ?c. the interface bonding strength was determined by bending and peeling tests, resistance, conductivity and micro hardness profiles were determined and microstructure in the interface region was observed by optical microscope. electrical resistance...

This review covers the emerging field of graphene reinforced water-based elastomers, which offer enhanced strength, elasticity, electrical and thermal conductivity other properties for a wide range application sectors.

Study Design Systematic review. Clinical Questions Compared with no stimulation, does electrical stimulation promote bone fusion after lumbar spinal fusion procedures? Does the effect differ based on the type of electrical stimulation used? Methods Electronic databases and reference lists of key articles were searched up to October 15, 2013, to identify randomized controlled trials (RCTs) compa...

OBJECTIVE To assess the effectiveness of surface neuromuscular electrical stimulation in the treatment of knee osteoarthritis. DESIGN Systematic review and meta-analysis of randomized controlled and controlled clinical trials METHODS Studies were identified from databases (MEDLINE, EMBASE, CINAHL, Sports Discus, PEDro and the Cochrane Library) searched to January 2011 using a battery of key...

Electrical properties of three kinds of poly(methyl methacrylate) (PMMA) with different tacticity, i.e. isotactic(i), syndiotactic(s), and atatic(a), were investigated for the application in field effect transistor. Metal-insulator-silicon structures were fabricated via spin coating PMMA on heavily doped p-type silicon (p-Si) followed by evaporating gold electrode. The electrical characteristic...

The magnetic field strength of both the magnet and gradient coils used in MR imaging equipment is measured in Tesla units, which are named for Nikola Tesla. This article presents the life and achievements of this Serbian-American inventor and researcher who discovered the rotating magnetic field, the basis of most alternating-current machinery. Nikola Tesla had 700 patents in the United States ...

Lodging, defined as the permanent displacement of aboveground parts, is a common problem to cause yield loss, deterioration in seed quality and difficult to harvest in canola (Brassica napus L.) crop production. This study aimed to develop a method for assessing crop lodging, to examine how agronomic practices affected the relationships between root lodging and electrical capacitance traits. Ca...

The electrorheological properties (ER) of natural rubber (XL)/alumina (Al2O3) composites were investigated in oscillatory shear mode under DC electrical field strengths between 0 to 2 kV/mm. SEM micrographs indicate a mean particle size of 9.873 ± 0.034 μm and particles that are moderately dispersed in the matrix. The XRD patterns indicate Al2O3 is of the β-phase polytype which possesses high i...
