Incidental blood agar-based recovery of Mycobacterium tuberculosis led us to further investigate this routine medium for primary isolation and culture of M. tuberculosis. Fifteen respiratory tract and eight lymph node Ziehl-Neelsen-positive specimens were inoculated in parallel into tubes containing egg-based medium and 5% sheep blood agar. Colonies appeared sooner on this medium than on the eg...

Suspensions of isolated cells were prepared from mouse livers that had been perfused via the portal vein with a buffered medium containing sucrose. The demonstration of metabolic activities in these cells was found to be critically dependent on the composition of the suspending medium. The cells showed considerable metabolic activity in a simple medium containing 0.06 to 0.20 M sucrose, but did...

A Triton-extracted model of Paramecium swims forwards when the Ca2+ concentration in the reactivation medium containing ATP is below 10(-6) M and swims backwards when Ca2+ concentration is above 10(-6) M. We found that cAMP (adenosine 3':5'-cyclic monophosphoric acid) inhibited Ca-induced backward swimming of the model and caused forward swimming even when the [Ca2+] was above 10(-6) M. This ef...

Glutamine synthetase (GS) plays an important role in nitrogen assimilation. The major GS of Mycobacterium tuberculosis is GlnA1, a type I GS whose activity is controlled by posttranscriptional modification by GlnE. GlnE is an adenylyl transferase comprised of an adenylylating domain and a deadenylylating domain which modulate GS activity. We previously demonstrated that GlnE is essential in M. ...

The zero-power reactor noise theory in a steady neutron multiplying medium was extended recently to a medium randomly varying in time. However, it was found that, for a time-varying medium where the transition probability randomly fluctuates, the treatment of the joint moments of the neutron number N and the medium state η by the forward master equation approach leads to a closure problem. The ...

We confront different models for medium modifications of the electromagnetic correlation function to recent dimuon spectra from the NA60 collaboration for central In-In collisions at the CERN-SPS. In the low-mass region (M.1.0 GeV), we evaluate medium modifications of the spectral properties of ρ-, ωand φ-mesons. In the intermediate-mass region (M>1.0 GeV), we employ schematic models for the mi...

We present a free-form medium of curation for digital arts catalogues, which connects an infinite zoomable canvas, sketching, and spatial arrangement of rich catalogue elements. We draw on an architectural theory that integrally joins the properties of building materials, construction techniques, and sites to develop a tectonic theory of media of digital curation The theory addresses media of c...

—We consider the conditions how two binary numbers can be superimposed on the same track with the use of different recording magnetic fields. As a result the average magnetization of longitudinal medium along the track can have three states:-M, 0 and +M. Possibility to perform logic operations with these states is considered. We demonstrate OR, AND, XOR and NOT operations and discuss a modifica...
