the textile industry has long been one of the largest of water users and nolluters and there has been little success in developing low cost treatment methods , which the industry urgently needs to lessen the pollution loads it discharges to streams. the obiective of this preparatory study was to determinen the effects o f coagulants and aid coagulant s as alum, ferrous sulfate , ferric sulfate ...

Pope et al. (2007) found lowered monthly mortality rates during a 1967–1968 copper smelter strike, coincident with and attributed to widespread reduced airborne sulfate levels. The authors cited three “intervention” studies associating particulate emissions reductions with mortality reductions as supportive. Evidence below suggests that mortality reductions in the study by Pope et al. and “inte...

Abstract The demand for copper is expected to outpace supply in the coming decades due part emergence of wind and solar technologies, which require about five times as much traditional energy sources. This work introduces a potentially transformative hydrometallurgical process extract from chalcopyrite, thereby sustain high rate production throughout 21 st century. Chalcopyrite reacted with van...

We conducted three 28-d experiments involving a total of 915 pigs to assess the relative efficacy of tribasic Cu chloride (Cu2[OH]3Cl) and Cu sulfate pentahydrate (CuSO4.5H20) in diets for weanling pigs. Experiments 1 and 2 were conducted at an experiment station (University of Kentucky), and Exp. 3 was conducted at a commercial feed company's swine research facilities (United Feeds, Inc.). The...

the vase life of cut flowers and foliage is often shortened by vascular occlusions that constrict vase solution supply. reduction in stem conductivity is typically caused by blockage of cut stem ends and xylem conduits by microbes, physiological plugging, and disruption of water columns in xylem vessels by cavitations and air emboli. cut flower and foliage longevity can be greatly affected by t...

Copper sulfate and other chelated or complex copper forms are commonly used to manage nuisance and noxious algae and invasive weeds through direct application to aquatic systems. Regulatory scrutiny and perceived non-target species impacts supported the need for an accurate risk assessment of fate and effects of copper applied as a pesticide. Copper inputs to aquatic systems originate from nume...

Microtubules (MTs) are self-assembling, protein-based, tubular structures several micrometers long with outer and inner diameters of 25 nm and 15 nm, respectively. This aspect ratio makes MTs ideal templates for producing nanowires for applications such as electrical nano-interconnects. MTs are poorly conductive and their use as interconnects necessitates their metallization. We report a proces...
