microscopy as “field based test” was compared with is900 blood pcr for the diagnosis and estimationof prevalence of mycobacterium avium subspecies paratuberculosis (map) in domestic livestock withclinical johne’s disease (jd). of 252 animals screened, 39.3 and 13.1% were positive by faecal microscopyand blood pcr, respectively. proportional agreement between “microscopy” and blood pcr was subst...

nanoscale science and technology has today mainly focused on the fabrication of nano devices. in this paper, we study the use of lithography process to build the desired nanostructures directly. nanolithography on polymethylmethacrylate (pmma) surface is carried out by using atomic force microscope (afm) equipped with silicon tip, in contact mode. the analysis of the results shows that the dept...

bio-directed synthesis of nanoparticles is an interesting field of rapid advancement for biologists,chemists and materials scientists, especially in light of efforts to find out green methods of inorganicmaterial synthesis. in the present study, green synthesis of platinum nanoparticles (ptnps) using sheepmilk is reported for the first time. by adjusting the concentrations of chloroplatinic aci...

in this work, for the first time, the rheological properties of nanofluids of lanthania nanoparticles (nps) in ethylene glycol (eg) as functions of shear rate, volume fraction, and temperature were measured. the results showed that both eg and the nanofluids behave as non-newtonian fluids at lower shear rates and transform to newtonian fluids at higher shear rates. the values of viscosity for b...
