Thermodynamics of Adsorption of n -Alkanes on Maleated Wood Fibers by Inverse Gas Chromatography.

The adsorption of n -heptane, n -octane, n -nonane, and n -decane on untreated wood fiber and wood fiber treated with maleated polypropylene was studied by inverse gas chromatography (IGC) at infinite dilution or zero surface coverage. The specific retention volume increased with increasing probe chain length, decreased with increasing column temperature, and increased with increasing maleated polypropylene concentration. The enthalpy of adsorption increased with increasing chain length of the probe vapors.

Healthcare reform: the strategies.

Literally dozens of comprehensive national healthcare reform bills are pending in Congress. In capsule, here are the main plans under discussion.

Regulatory and legal aspects of outpatient surgery.

This is a brief summary of the regulatory and other legal issues that may be raised by the provision of surgery outside of the hospital environment. Despite these potential problems, however, outpatient surgery embodies significant potential for hospitals, physicians, patients, and third-party payers. Outpatient surgical facilities embody the potential to achieve two of the government's primary goals: the provision of high-quality services and the reduction of health care costs.
