    Notes: The nutritional value and the possibilities of utilization of the aquatic weed, Nymphoides cristatum as feed for young Labeo rohita, were evaluated in terms of growth, conversion efficiency, specific activity of digestive enzymes, bio-chemical composition of flesh and microbial composition of intestine (cellulolytic bacteria), in a 60-day laboratory feeding trial. The daily dry matter (DM) intake of the control diet (FC) prepared with mustard oil cake:rice bran (3:7) and aquatic weed (FN) prepared with N. cristatum leaf meal was 4918 and 5948 mg, digestible DM of 4179 and 5185 mg and digestible energy (DE) of 53.56 and 84.33 kJ kg–1 fish, respectively. The specific growth rate was 3.18 and 3.8 with the control diet and the weed, respectively. Fish fed with the weed showed better average daily gain (ADG%), feed conversion ratio (FCR) and protein efficiency ratio (PER). The specific activity of proteolytic and amylolytic enzymes showed significant increase (P 〈 0.001) in fish fed with the weed. Culture of intestinal mucosa revealed the presence of cellulolytic bacteria, the count per cm being higher in the intestinal bulb (3.70 × 104–4.32 × 104) followed by middle intestine (2.16 × 104–2.29 × 104) and posterior intestine (1.26 × 103–1.35 × 103) in the fish fed with the diet FN as compared with the diet FC. The preliminary study indicate the possibilities of incorporation of the aquatic weed, N. cristatum in the diet of L. rohita substituting conventional feed ingredients.

    Notes: Abstract The species Cymbopogon winterianus Jowitt is believed to have originated from the well-known species Cymbopogon nardus, type Maha Pengiri, referred to as Ceylonese (Sri Lankan) commercial citronella. Cymbopogon winterianus Jowitt was named after Winter, who raised its population as a separate species in the 19th century. C. winterianus was introduced into Indonesia and became commercially known as the Javanese citronella. The Javanese type C. winterianus material was introduced into India for the commercial cultivation of this crop during 1959. Varieties of this species have been developed later by the use of breeding procedures from the same introduced material. A comparative analysis of yields of herb, oil percentage and oil constituents for eight prevalent C. winterianus cultivars comparing them between themselves as well as against an accession of C. nardus has been carried out. All these accessions were analyzed at the molecular level for the similarity and genetic distances through RAPD profiling, using 20 random primers. More than 50% divergence was observed for all the C. winterianus accessions in relation to C. nardus accession CN2. The clustering based on the similarity matrices showed a major cluster of six accessions, consisting of two sub-clusters. The accession C. nardus CN2 got carved out along with two C. winterianus accessions, CW2 and CW6. On the other hand, the accessions CW2 and CW6 demonstrated distinct identities compared to CN2 at the DNA level.

    Determination of the equation of state of quark matter from $J/\psi$ and $\Upsilon$ suppression at RHIC and LHC (2000)

    Notes: Abstract. The long lifetime of the quark–gluon plasma likely to be created in relativistic heavy ion collisions at RHIC and LHC energies renders it sensitive to the details of the equation of state of the quark matter. We show that the $p_{\mathrm{T}}$ dependence of the survival probability of the directly produced $J/\psi$ at RHIC energies and that of the directly produced $\Upsilon$ at LHC energies is quite sensitive to the speed of sound in the quark matter, which relates the pressure and the energy density of the plasma. The transverse expansion of the plasma is shown to strongly affect the $J/\psi$ suppression at LHC energies.

    $J/\psi$ gluonic dissociation revisited: I. Fugacity, flux and formation time effects (2004)

    Notes: Abstract. We revisit the standard treatment due to Xu et al. of $J/\psi$ suppression due to gluonic bombardment in an equilibrating quark-gluon plasma. Effects arising from gluon fugacity, relative g- $\psi$ flux, and $\psi$ meson formation time are explicitly incorporated in the formulation of the gluon number density, velocity-weighted cross section, and the survival probability. Our new formulae are applied to a numerical study of the pattern of $J/\psi$ suppression in the central rapidity region at RHIC/LHC energies. The temperature and transverse momentum dependence of our graphs have noticeable differences from those of Xu et al.

    Electron paramagnetic resonance and Mössbauer spectroscopy of transition metal ion doped mullite (2000)

    Notes: Abstract Appreciable difference in the properties of undoped and oxide-doped mullite are observed. The oxidation state of cation, its concentration and the position of the mullite lattice occupied by it appear to be the responsible factors. Mullite has, therefore, been doped with four transition metal ions, Mn, Fe, Cr and Ti. With the help of EPR and Mössbauer spectroscopy (supplimented by X-ray diffractometry) the oxidation states of these ions and the mullite lattice sites where they enter has been investigated. It was observed that Mn ion was present in Mn2+ and Mn3+ states, the former remained as clusters and the latter occupied the octahedral sites in the mullite lattice. Only Fe3+ ion was detected and conclusive evidence was obtained for the entry of Fe3+ in the octahedral lattice position of mullite from the analysis of Mössbauer spectra with the help of a specially written computer programme. The Cr ion entered the mullite structure only in the Cr3+ state. The change in lattice parameters of Cr doped mullite were measured by the XRD technique. The results showed that the expansion of b-axis was more than that of the a-axis which supported the presence of Cr3+ ion in the octahedral site of mullite lattice. The absence of signal in the EPR spectra of Ti doped mullite suggested the presence of only Ti4+ (3d0) ion. Very low electrical resistivity of Ti doped mullite and close similarity between mullite and Al2TiO5 structures stood as evidence for incorporation of Ti4+ ion in the octahedral site of mullite lattice by replacing Al3+ ion.

    Frequency dependence of the photonic noise spectrum in an absorbing or amplifying diffusive medium (2001)

    Notes: Abstract: A theory is presented for the frequency dependence of the power spectrum of photon current fluctuations originating from a disordered medium. Both the cases of an absorbing medium (“grey body”) and of an amplifying medium (“random laser”) are considered in a waveguide geometry. The semiclassical approach (based on a Boltzmann-Langevin equation) is shown to be in complete agreement with a fully quantum mechanical theory, provided that the effects of wave localization can be neglected. The width of the peak in the power spectrum around zero frequency is much smaller than the inverse coherence time, characteristic for black-body radiation. Simple expressions for the shape of this peak are obtained, in the absorbing case, for waveguide lengths large compared to the absorption length, and, in the amplifying case, close to the laser threshold.
