A new format for solid-phase immunoassays has been developed in which a monoclonal antibody-coated membrane, incorporated into a cylindrical, disposable device, regulates sample and reagent delivery. We illustrate the method with a two-site, immunoenzymometnc assay that can detect human choriogonadotropin at less than 50 mt. units/L (4 pg/L) in urine and less than 25 mt. units/L (2 j.tg/L) in s...

So, climate change and conflict is back in the media, seemingly with the strength of science behind it. I’ve been a rather direct, harsh critic of some work on this connection before, at least in part because I am deeply concerned that work on this subject (which remains preliminary) might disproportionately influence policy decisions in unproductive or even problematic directions (i.e. by cont...

Extensive testing, at pressure "'evels from 3U to 758 MPa (5,000 to 110,000 PSI) was done at Aberdeen Proving Ground to evaluate 15 different types of electrical pressure transducers used in large caliber weapons. When using a given tvoe of transducer, the ability to consistently distinguish dynamic pressure variations as small as 0.2% was demonstrated. Yet different models of pressure transduc...

This paper presents the interface developments and music of the duo “interface,” formed by Curtis Bahn and Dan Trueman. We describe gestural instrument design, interactive performance interfaces for improvisational music, spherical speakers (multi-channel, outward-radiating geodesic speaker arrays) and Sensor-Speaker-Arrays (SenSAs: combinations of various sensor devices with spherical speaker ...

The central drift chamber for the BaBar detector at the PEP-II Bfactory at SLAC is a cylindrical chamber with a length of 280 cm and outer radius of 81 cm. It consists of 40 layers of small hexagonal cells arranged in 10 axial and stereo super-layers. In order to minimize multiple scattering, light materials are used for the mechanical structure, and the gas mixture is Helium based. The pulse-h...

purpose : to evaluate intraocular pressure (iop) and anterior chamber depth (acd) change after phacoemulsification with posterior chamber intraocular lens implantation methods : in this quasi-experimental study, 84 patients with senile cataract were included. all patients had normal iop. patients with traumatic and complicated cataract, any history of uveitis, glaucoma, or other ocular disease ...

introduction tetralogy of fallot (tof) in the absent of pulmonary valve is a rare congenital anomaly (3%of tof patients). case presentation we are presenting an 18- year-old male with history of dyspnea on exertion and cyanosis since childhood. despite the diagnosis of congenital heart disease, no intervention was done due to his poor socioeconomic culture. at age of 18, he referred to our cent...

the ultrastructure of the cells, na+, k+-atpase activity and immunolocalization were examined in the barnchial chamber of libellula lydia (drury, 1773) larvae. na+,k+-atpase activity and localization were performed through biochemical techniques and immunofluorescence light microscopy using a mouse monoclonal antibody iggα5, respectively. the branchial chamber possesses six pair gills lamellae ...
