I introduce a new field: electro-photonics, where the best of the electronic and photonic technologies are combined to increase the capacity, flexibility and energy efficiency of communications systems. OCIS codes: (060.0060) Fiber optics and optical communications; (070.2025) Discrete optical signal processing; (130.0250) Optoelectronics; (130.3120) Integrated optics devices; (130.4110) Modula...

The Asunci6n rift, eastem Paraguay, is a remarkable structure, first noticed by Degraft. It is a segmented, "Iazy Z", left-stepping rlft system, starting at Asunci6n, to the west, with a NW-8E direction. It then tums next into a E-W treneling middle saction, finally resuming, to the east, its inltlal NW-8E course. Its endings, at both extremes, are ill-defined. Total E-W length is about 150 Km,...

background: electrochemical methods, as one of the advanced oxidation processes (aops), have recently been applied to remove different contaminants from water and wastewater. this study compares the performance of anodic oxidation (ao) and electro-fenton (ef) methods on waste sludge treatment. methods: this experimental study was performed on real sludge and the effect of operating parameters s...

this paper presents a comprehensive case study on electro-mechanical analysis of mems[1] variable capacitors. using the fundamental mechanical and electrical equations, static and dynamic behaviors of the device are studied. the analysis is done for three different modes, namely: dc (static mode), small signal ac and large signal regime. a complete set of equations defining dynamic behavior of ...

conclusions pyeloplasty, with adequate spatulation, hemostasis and a watertight anastomosis, represents the mainstay of successful pyeloplasty and there may be no significant benefit for urethral stenting, especially in non-complicated cases. background anderson-hynes dismembered pyeloplasty is the gold standard therapeutic approach to ureteropelvic junction obstruction (upjo). use of a drainag...

background the incidence of prostatic abscess (pa) has markedly declined with the widespread use of antibiotics and the decreasing incidence of urethral gonococcal infections. objectives to evaluate different treatment methods for prostatic abscess and to describe technical points that will improve the outcome of transurethral (tur) drainage of prostatic abscess. patients and methods we perform...

AIM The aim is to investigate, in relation to the volume of blood drained, which type drainage to use after thyroidectomy natural drainage or negative drainage. MATERIAL OF STUDY 141 patients who underwent total thyroidectomy for multinodular thyroid disease between 22 November 2012 and 7 November 2013 were included in the present study. For the 141 patients a randomized method was used with ...

The synthesis and characterization of a unique (electro)chemiluminescent monomer based on a terthienyl system, and its corresponding polymer which is the first example of an electro-active chemiluminescent polymer bearing a pyridazine appendage, are described.
