BACKGROUND Esophageal dilation by rendezvous is a useful technique for the treatment of complicated esophageal strictures. METHODS AND RESULTS We present a case of a 74-year-old man with chronic dysphagia caused by a complete cervical esophageal stricture that developed after external beam radiotherapy for treatment of papillary thyroid carcinoma. During attempted dilation using the rendezvou...

Solid/liquid separations are commonly the first step in any wastewater treatment. Such technologies are mature and new developments are rare. However, in the last decade some significant improvements in separation techniques for industrial wastewater pretreatment have been implemented. Advances in the technology include more efficient, faster centrifugal mixing of treatment chemicals and wastew...

Groundwater is one of our most valuable natural resource. More than 50% of the U.S. population depends on groundwater for domestic use and more than 95% of the rural population is dependent on groundwater. A major portion of industries and agriculture use groundwater. These numbers suggest that the personal and economic health of the nation is dependent on groundwater. Contamination of groundwa...

Nearly 4% of all primary recompression treatments in Scotland employ saturation tables (helium/oxygen-oxygen/air or oxygen/air alone). These cases usually involve divers presenting at the surface who then develop deteriorating spinal cord injury with varying degrees of cerebral involvement. Treatment is delivered either through immediate saturation therapy or through conversion of failing or fa...

Several nematicides have been used to disinfest rice seeds contaminated with the white tip nematode, Aphelenchoides besseyi. We measured the efficacy of a standard disinfestation treatment that consists of soaking seeds in an aqueous emulsion of fenitrothion or fenthion and subsequently air-drying the seeds. We also measured the efficacy of the same treatments but without addition of nematicide...

Electrospinning is a simple and versatile technique that relies on the electrostatic repulsion between surface charges to continuously draw nanofibers from a viscoelastic fluid. Electrospinning can generate nanofibers with a number of secondary structures. Surface and/or interior of nanofibers can be functionalized with molecular species or nanoparticles during or after an electrospinning proce...
