The Ziehl-Neelsen method is probably the best known and most frequently used procedure for staining tubercle bacilli. The method requires controlled heating for its success. However, in developing countries, such as India, where most laboratories rely mainly on spirit lamps as a source of heat, the Ziehl-Neelsen method often cannot be carried out because(More)

One of the biggest obstacles to the correct diagnosis and efficient treatment of tuberculosis is the absence of a rapid technique for culturing tubercle bacilli and for testing their susceptibility to antituberculosis drugs. Current procedures typically take 6-10 weeks to perform. This article describes a simple, rapid, reliable and cheap method of(More)
Nanofiber composites (Polyimide/f-SWCNT) of Pyromellitic dianhydride, 4,4'-Oxydianiline, and 4,4'-(4,4'-isopropylidene diphenyl-1,1'-diyl dioxy) dianiline (PMDA-ODA/IDDA) and surface-functionalized single walled carbon nanotubes (f-SWCNT) were made by electrospinning a solution of poly(amic acid) (PAA) containing 0-2 wt% f-SWCNT followed by thermal(More)
The ability of a room-temperature air-atmosphere (RTAA) co-precipitation method to tune the magnetic properties of iron oxide nanoparticles was investigated. It was demonstrated that superparamagnetic nanoparticles with different particle sizes ranging from 7 to 25 nm and magnetic properties with saturation magnetization between 2 to 75 emu g(-1) can be(More)
The thermal convection of compressible Walters’B′ Rotating viscoelastic fluid is considered in the presence of uniform vertical magnetic field. By applying normal mode analysis method, the dispersion relation has been derived and solved analytically. For stationary convection, Walters’B′ viscoelastic fluid behaves like an ordinary (Newtonian) fluid. It is(More)
