introduction: dye removal from industrial wastewater has been considered as one of the most environmental issues. recently, new methods of treatment such as catalytic ozonation have been used to increase dye removal efficiency. so, the efficiency of catalytic ozonation by copper coated zeolite as a catalyst in the removal of reactive red 198 was investigated. materials & methods: in order to re...

UNLABELLED We present a tool, diCal-IBD, for detecting identity-by-descent (IBD) tracts between pairs of genomic sequences. Our method builds on a recent demographic inference method based on the coalescent with recombination, and is able to incorporate demographic information as a prior. Simulation study shows that diCal-IBD has significantly higher recall and precision than that of existing s...

OBJECTIVE The primary objective of the three studies reported in this paper was to evaluate the effects of new dentifrices containing 1.5% arginine, an insoluble calcium compound, and fluoride for their ability to promote remineralization of demineralized enamel, and to prevent mineral loss from sound enamel specimens. A secondary objective was to determine the effects on plaque metabolism with...

Story in Brief The phosphorus concentration in ruminal fluid was determined for steers limit-fed rations with phosphorus concentrations ranging from .06 to .17 percent. Ruminal phosphorus concentration was increased with phosphorus intake at dietary concentrations below .12 percent for steers. This relationship was employed to estimate the ruminal availability of phosphorus from four phosphorus...

| Because of the importance of the security issues in the management of medical information, we suggest to use watermarking techniques to complete the existing measures for protecting medical images. We discuss the necessary requirements for such a system to be a c cepted b y m e dical staa and its complementary role with respect with existing security systems. We present diierent scenarios, on...

As a pre-treatment method of refractory gold ore, carbonaceous matter (C-matter) flotation was investigated with multi-stage by rougher, scavenger, and cleaner stages. Different dosages kerosene MIBC (4-Methyl-2-pentanol) were applied the optimum dosage selected testing in each stage. With combination stage, four circuit designs suggested, which single-stage rougher (R), rougher-scavenger (R+S)...
