    Quantum dynamics of molecules in 4He nano-droplets: Microscopic Superfluidity

    Full text link
    High resolution spectroscopy of doped molecules in 4He nano-droplets and clusters gives a signature of superfluidity in microscopic system, termed as microscopic superfluidity. Ro-vibrational spectrum of 4HeN-M clusters is studied with the help of some important observations, revealed from experiments (viz., localised and orderly arrangement of 4He atoms, although, being free to move in the order of their locations; individual 4He atoms can not be tagged as normal/ superfluid, etc.) and other factors (e.g., consideration that the 4He atoms which happen to fall in the plane of rotation of a molecule, render a equipotential ring and thus, do not take part in rotation; etc.) which effect the rotational and vibrational spectrum of the system. This helps us in successfully explaining the experimental findings which state that the rotational spectrum of clusters have sharp peaks (indicating that the molecule rotates like a free rotor) and moment of inertia and vibrational frequency shift have a non-trivial dependence on N

    Neoliberalism and University Education in Sub-Saharan Africa

    This article reviews the history of university development in Sub-Saharan Africa (SSA) and discusses the impact of neoliberal policies. This will be followed by an examination of the problems facing universities in the region. The following questions will be explored: (a) Are the existing universities in SSA serving the development needs of the region? (b) Are these universities up to the task of moving SSA out of the predicaments it faces such as famine, HIV/AIDS, poverty, diseases, debt, and human rights abuses? Finally, the article argues that for universities to play a role in the development of the region, a new paradigm that makes university education a public good should be established

    High Diversity of Cryptosporidium Subgenotypes Identified in Malaysian HIV/AIDS Individuals Targeting gp60 Gene

    BACKGROUND: Currently, there is a lack of vital information in the genetic makeup of Cryptosporidium especially in developing countries. The present study aimed at determining the genotypes and subgenotypes of Cryptosporidium in hospitalized Malaysian human immunodeficiency virus (HIV) positive patients. METHODOLOGY/PRINCIPAL FINDINGS: In this study, 346 faecal samples collected from Malaysian HIV positive patients were genetically analysed via PCR targeting the 60 kDa glycoprotein (gp60) gene. Eighteen (5.2% of 346) isolates were determined as Cryptosporidium positive with 72.2% (of 18) identified as Cryptosporidium parvum whilst 27.7% as Cryptosporidium hominis. Further gp60 analysis revealed C. parvum belonging to subgenotypes IIaA13G1R1 (2 isolates), IIaA13G2R1 (2 isolates), IIaA14G2R1 (3 isolates), IIaA15G2R1 (5 isolates) and IIdA15G1R1 (1 isolate). C. hominis was represented by subgenotypes IaA14R1 (2 isolates), IaA18R1 (1 isolate) and IbA10G2R2 (2 isolates). CONCLUSIONS/SIGNIFICANCE: These findings highlighted the presence of high diversity of Cryptosporidium subgenotypes among Malaysian HIV infected individuals. The predominance of the C. parvum subgenotypes signified the possibility of zoonotic as well as anthroponotic transmissions of cryptosporidiosis in HIV infected individuals

Physikalisches Institut, Universit\""{a}t zu K\""{o}ln, Z\""{u}lpicher Str.; Steacie Institute for Molecular Sciences, National Research Council of CanadaThe millimeter wave spectrum of the isotopically substituted CO dimer, (13C16O)2(^{13}C^{16}O)_{2} has been studied for the first time, confirming and extending a recent infrared study [1]. A total of 87 transitions in the 77 - 180 GHz region have been assigned and analyzed with a model-independent term value scheme involving 57 rotational levels with J=0J = 0 to 8. The levels can be classified into 7 ``stacks'' which have symmetry classifications of either A+/BA^{+}/B^{-} or A/B+A^{-}/B^{+}, and K -values of either 0 or 1. For the normal isotope, symmetry and nuclear spin statistics cause alternate rotational levels to be missing, but for (13C16O)2(^{13}C^{16}O)_{2}, all levels are present with an intensity alternation of 1:3 between the A and B symmetries. The four A+/BA^{+}/B^{-} stacks have not previously been observed, and the lowest of them establishes the tunneling splitting of (13C16O)2(^{13}C^{16}O)_{2} to be 3.769cm13.769 cm^{-1}, slightly larger than the (12C16O)2(^{12}C^{16}O)_{2} value [2] of 3.731cm13.731 cm^{-1}. Even though a considerable amount of precise experimental data is now available for the CO dimer, we still have little theoretical insight into its structure and tunneling dynamics
