摘要： A tester for evaluating pullout load capacity and bond quality of anchor bolts embedded in concrete includes a Schmidt hammer for measuring a rebound number and an ultrasonic pulse velocity tester for measuring the transit time of a pulse transmitted through concrete surrounding an anchor bolt. The rebound number and the transit time are combined and matched against a database record which identifies the pullout load capacity and the bond quality. The transit time is matched to thresholds of transit times associated with porosity, internal cracking, air voids, and water pockets located around the embedded anchor bolt. The Schmidt hammer is further modified by the incorporation of a digital level for measuring the vertical and horizontal angles of inclination of the plunger with the concrete surface, a guide tube for supporting the plunger, and by using a convex plunger tip for improved registration with anchor bolt head.

摘要： The invention is directed to a surgical device which is externally used as aiming device that permits accurate placement of surgical wire to mend a supracondylar fracture. The device of the invention decreases operative time, risks of the re-dislocation through continuous manipulation, radiology exposure for both the patient and operation room staff, and to decreases anesthesia duration. It is also directed to surgical use of the device for repair of a supracondylar fracture and to methods for making it.

摘要： Silica nanocarriers hybridized with superparamagnetic iron oxide nanoparticles (“SPIONs”) and curcumin through equilibrium or enforced adsorption technique. Methods for dual delivery of SPIONs and curcumin to a target for diagnosis or therapy, for example, for SPION-based magnetic resonance imaging or for targeted delivery of curcumin to a cell or tissue. The technique can be extend to co-precipitation of mixed metal oxide involving Ni, Mn, Co and Cu oxide. The calcination temperature can be varied from 500-900° C. The nanocombination is functionalized with chitosan, polyacrylic acid, PLGA or another agent to increase its biocompatibility in vivo.

摘要： Methods of forming spinel ferrite nanoparticles containing a chromium-substituted copper ferrite as well as properties (e.g. particle size, crystallite size, pore size, surface area) of these spinel ferrite nanoparticles are described. Methods of preventing or reducing microbe growth on a surface by applying these spinel ferrite nanoparticles onto the surface in the form of a suspension or an antimicrobial product are also described.

摘要： Water treatment structures may have at least a first geotextile fabric layer; a second geotextile fabric layer; a third geotextile fabric layer; a first filler layer with plastic particles, arranged between the first and second geotextile fabric layers; and a second filler layer with plastic particles, arranged between the second and third geotextile fabric layers, wherein the geotextile fabric layers and the filler layers are within a housing, and wherein the structure is configured such that contaminated water proceeds sequentially through the first geotextile fabric layer, the first filler layer, the second geotextile fabric layer, the second filler layer, and the third geotextile fabric layer. Methods of treating wastewater may involve passing wastewater, after optional oxygenating and pre-filtering, through such alternating layers of geotextile, preferably nonwoven, and polymer particles.
