Crystalline phases of alkyl-thiol monolayers on liquid mercury.
The structure of octadecanethiol monolyers on liquid Hg surfaces, measured with subangstrom resolution, evolves with increasing coverage from a laterally disordered phase of surface-parallel molecules to ordered rotator phases of surface-normal molecules. For the latter, an abrupt transition is found at 19 A(2)/molecule from a rectangular packing of molecules tilted by 27 degrees in the nearest...
متن کاملPrecautions for Patients with Diabetes Undergoing Surgery
There is a rising incidence and prevalence of diabetes mellitus. About 50% of people with diabetes mellitus are unaware of their condition. Approximately 25% of all patients with diabetes undergoing surgery are undiagnosed on admission to hospital. Patients with diabetes have a higher risk of cardiovascular disease. Patients with diabetes have a higher perioperative risk. They are more likely b...

متن کاملCompliance with universal precautions among pediatric residents.
BACKGROUND There are few data on the rate of compliance with universal precautions among pediatricians. We hypothesized that compliance in pediatrics would be poor because of the intrinsic difficulties in performing invasive procedures in small subjects. DESIGN Prospective, observational study. SETTING Tertiary care children's hospital. STUDY PARTICIPANTS A convenience sample of pediatric...
متن کاملPolymerization of Alkyl Acrylates and Alkyl Methacrylates with Starch
A series of C4-C 12 alkyl acrylates and methacrylates was polymerized with starch by irradiating starch-monomer mixtures with 60CO. Homopolymers were extracted with cyclohexane. The amounts of insoluble versus soluble synthetic polymer in polymerizations run with alkyl acrylates varied less with the chain length of the alkyl substituent than in the polymerizations run with alkyl methacrylates: ...
