Opening and refolding of simian virus 40 and in vitro packaging of foreign DNA

Simian virus 40 (SV40) can be disassembled under mild conditions by reducing disulfide bonds in the capsid and removing calcium ions. The nucleoprotein complexes formed, analyzed by electron microscopy, were circular and made up of 59 +/- 4 subunits, each ...

Squeezed Polaritons In Confined Systems

Vincenzo Savona, Paolo Schwendimann

We discuss the statistical properties of polaritons in quantum wells embedded in a microcavity. In particular we evaluate the amount of squeezing of confined exciton polaritons in a GaAs quantum well. The limit of a large cavity is also considered. ...

Photochemistry, charge-transfer states, and laser applications of small molecules in rare gas crystals

Majed Chergui

A microscopic, theor., and exptl. description of an elementary solid state photoreaction, i.e. the dissocn. of a small mol. in a rare lattice is presented. The ingredients and results of mol. dynamics calcns. for the dissocn. of F2, Cl2, HI, and H2O mols. ...

Un principe de concentration-compacité pour les suites de surfaces riemanniennes

Marc Troyanov

We study sequences of metrics on a compact surface with bounded area and curvature and I prove that if the conformalstructure of these metrics remains bounded, then either the sequence contains a convergent subsequence, or there exists a point at which a c ...

A Fourier Transform Infrared Spectroscopic Study of CO2 Methanationon Supported Ruthenium

Albert Renken, Ravindranathan Thampi

Diffuse-reflectance infrared Fourier transform (DRIFT) spectroscopy has been used to study in situ, the low-temperature (T < 200°C) methanation of CO2 over Ru on TiO2 supports and on Al2O3. For 3.8% Ru/TiO2, the reaction exhibits an activation energy (Ea) ...

Effects of methotrexate on transfected DNA stability in mammalian cells

Florian Maria Wurm

The chromosomal locations, amounts, and level of expression of transfected, amplified c-myc and dihydrofolate reductase sequences were measured in cells cultured in the presence and absence of methotrexate. These studies show that the location and amount o ...

On the Dagan model of solute transport in groundwater: Foundational aspects

David Andrew Barry

The convection-dispersion equation (CDE) developed by Dagan [1984] to predict the ensemble-average concentration of a conservative solute in groundwater has been used successfully to interpret recent tracer experiments in a sand aquifer at the Borden site ...

Two-dimensional Fourier transform ion cyclotron resonance mass spectrometry

Geoffrey Bodenhausen

Two-dimensional Fourier transform (2D FT) spectroscopy was applied to ion-cyclotron resonance (ICR) to obtain direct evidence for mass transfer due to ion-mol. collisions. The 2D FT ICR expt., which is closely analogous to 2D exchange NMR spectroscopy (NOE ...

Absence of detectable serum interferon in acute and chronic viral hepatitis

Michel Aguet

Amounts of interferon were measured in sera from 59 patients with acute viral hepatitis and 49 patients with chronic hepatitis B and compared to those from patients with nonviral liver disease or influenza, and from healthy controls. In all patients with a ...

Solid state carbon-13 NMR spectroscopy: the isomer distribution in the solution and solid phases of PdCl2(PMe2Ph)2

Geoffrey Bodenhausen

A solid-state 13C NMR spectrum, obtained with cross-polarization and magic-angle sample spinning, and a high-resoln. 13C NMR spectrum of a 0.07 M CHCl3 soln. indicated the presence of a 1:1 cis-trans ratio of the PdCl2(PMe2Ph)2 isomers in the solid-state. ...
