Following four outbreaks of paralytic shellfish poisoning on Kodiak Island, Alaska, during 1994, medical records of ill persons were reviewed and interviews were conducted. Urine and serum specimens were analyzed at three independent laboratories usi

The instrumentation used in the investigation is considered, giving attention also to a block diagram of the apparatus used for measuring crystal-field spectra. The basic object of the studies was to identify the states of transition elements in luna

The wavelength shift with pressure of the ruby R1 fluorescence line (Δλ) has been calibrated in the diamond‐window pressure cell from 0.06 to 1 Mbar. This was done by simultaneously making specific volume measurements of four metals (Cu, Mo, Ag,

Force per unit area measurements made in the megabar pressure cell, independently of other pressure calibration systems, are consistent with the ruby R1 scale of Mao, Bell, Shaner, and Steinberg and its extrapolation to 1.4 Mbar. Physical analysis of

The room temperature static compression of CaO has been measured in a diamond anvil cell to 1.35 Mbar. The compression of the Bl phase and the volume change at the Bl to B2 transition agree with previous diamond cell results. The B2 phase has been ob

Fassaitic pyroxene from the Angra dos Reis meteorite has striking spectral properties. The57Fe Mossbauer spectra show no Fe3&+;, and thus the absorption is thought to originate from a complex charge-transfer process. Intense absorption at 480 nm domi

Experiments with a chrome-iron spinel from Lesotho (Free State), a spinel from the Philippines, and two lunar spinels have led to a system for assigning crystal-field transitions to observed absorption bands of chromium and iron. It was possible to d

Using a five-pass interferometric Brillouin spectrometer, we have measured the pressure dependence of longitudinal- and transverse-acoustic velocities and refractive index of solid $n$-${\mathrm{H}}_{2}$ and $n$-${\mathrm{D}}_{2}$ at room temperature
