Proteinaceous material usually accounts for much of the total nitrogen and organic carbon in marine sediments. Thus, decomposition of protein is frequently investigated as a measure of labile organic matter turnover. The fraction of protein that escapes remineralization to CO2 undergoes transformations that may reflect pathways of preservation in sedimentary environments. We analyzed the molecu...

To test for dose and duration effects of residual sedation, ethanol (0.0, 0.5, and 0.9 g/kg) was administered (at 0830, 1030, and 0730 hr, respectively) to 10 healthy, normal-sleeping men, aged 21-35 years. The Multiple Sleep Latency Test was conducted at 0930, 1130, 1330, 1530, 1730, 1930, and 2130 hr, and a divided attention performance assessment was done at 1400, 1600, 1800, and 2000 hr. Br...

Habitat use by a C. capucinus troop was studied in an agricultural landscape during late dry season (March-April 1994) in northwest Costa Rica. Riparian forests, palm canals and living fence rows accounted for 82% of observations, significantly more than the other six habitats present. The study troop consumed 24 species of plants and five animals. Feeding concentrated on the introduced African...

Patients with laryngeal lesions were observed and the lesions were recorded with an electronic videoendoscope system using the PENTAX EPM-3300 video processor and the PENTAX VNL-1330 endoscope portion. The electronic videoendoscope system differs from the conventional fiberoptic endoscope connected to a video camera in that a small monochrome charge-coupled device (CCD) chip is built in the tip...

Original scientific paper Objective parameters of the room acoustics quality are obtained from the impulse response, which is measured using the appropriate PC based acoustic measurement system with two types of loudspeakers. Such measurement gives the impulse response that is the result of measurement of the entire system, which consists of the room and electro acoustics equipment. In order to...
