This study was designated to describe clinical and biological features of patients with a suspected diagnosis of dengue fever/dengue hemorrhagic fever during an outbreak in Central Vietnam. One hundred and twenty-five consecutive patients hospitalized at Khanh Hoa and Binh Thuan Provincial hospitals between November 2001 and January 2002 with a diagnosis of(More)
Parametrized surfaces of low degrees are very useful in applications, specially in Computer Aided Geometric Design and Geometric Modeling. The precise description of their geometry is not easy in general. Here we study surfaces of bidegree (1,2). We show that, generically up to linear changes of coordinates, they are classified by two continuous parameters(More)
SiC5 in its (3)Σ ground state has been produced by trapping the products from the laser evaporation of a sintered silicon-carbon rod in solid Ar. For the first time a vibrational fundamental has been measured, the ν4(σ) asymmetric stretch at 936.9 ± 0.2 cm(-1). Comparison of observed (13)C and (29,30)Si isotopic shifts with the predictions of(More)
The Fourier transform infrared spectrum of SiC5Si was observed by trapping the vapor from the Nd:YAG laser ablation of sintered Si/C rods in solid Ar at ∼20 K. Measurements of (13)C and (29,30)Si isotopic shifts have enabled the identification of the ν5(σu) vibrational fundamental of the linear isomer of SiC5Si at 1590.8 ± 0.2 cm(-1). The results are in(More)
