The reactivity of different narrow electroencephalographic (EEG) frequencies (4–6, 6–8, 8–10 and 10–12 Hz) to three types of emotionally laden film clips (aggressive, sad, neutral) were examined. We ...observed that different EEG frequency bands responded differently to the three types of film content. In the 4–6 Hz frequency band, the viewing of aggressive film content elicited greater relative synchronization as compared the responses elicited by the viewing of sad and neutral film content. The 6–8 Hz and 8–10 Hz frequency bands exhibited reactivity to the chronological succession of film viewing whereas the responses of the 10–12 Hz frequency band evolved within minutes during film viewing. Our results propose dissociations between the responses of different frequencies within the EEG to different emotion-related stimuli. Narrow frequency band EEG analysis offers an adequate tool for studying cortical activation patterns during emotion-related information processing.
Thirty-four males and 45 females who participated in household surveys 15 or 25 years earlier in rural Denmark were interviewed in 1982 about present and past food habits. Comparison of the ...information from the survey and the two interviews indicates that recall of past diet is strongly influenced by present dietary habits. As the relative classification of individuals according to their food habits appears to have changed little over time, information on current diet, perhaps supplemented by information on particular changes, can provide useful classification of individuals for epidemiologic purposes.
Distribution of the trophic peptide somatomedin C (Sm-C; insulin-like growth factor I; IGF-I) immunoreactivity was mapped in normal Achilles and tibialis anterior tendons. The spindle-shaped tendon ...fibroblasts showed faint perinuclear staining. Fibroblasts in the paratenon mostly had a more intense IGF-I immunoreactivity, i.e. faint to moderate. When analysing either tendon in detail, areas with more intense IGF-I immunoreactivity could be recognized and seemed to correlate with areas of high mechanical stress. Increased mechanical load induced over 3 days elevated IGF-I immunoreactivity throughout the cytoplasm of tendon fibroblasts. Peak intensity was reached in 7 days, and thereafter the IGF-I immunoreactivity seemed to decrease irrespective of persistent high mechanical load. Training the animals on a treadmill for from 20 up to 60 min per day for 5 days induced after 3-5 days increased IGF-I immunoreactivity throughout the cytoplasm of the tendon and paratenon fibroblasts. Sudden curtailment of loading the Achilles tendon resulted in a marked reduction of the IGF-I immunoreactivity in most fibroblasts within 3 days. After a week only a small number of tendon fibroblasts showed any IGF-I immunoreactivity. The IGF-I immunoreactivity of tendon fibroblasts thus correlates to mechanical loading of the tendon. It is proposed that IGF-I may have a trophic influence on tendon and paratenon cells by autocrine and/or paracrine mechanisms.
Using orbital imaging radar, we detected a double circular structure, located in the southeastern part of the Libyan Desert, which is partially hidden under sandy sediments. Fieldwork confirmed it to ...be an unknown double impact crater, each crater having a diameter of about 10 km, younger than 140Ma. Sampling on the site enabled the observation of quantities of shatter cone structures and impact breccias containing planar fractures.
Biophysical parameters and L-band polarimetry synthetic aperture radar observation data were taken for 59 test sites in Tomakomai national forest, which is located in the northern part of Japan. ...Correlations between the derived sigma HH 0 , sigma HV 0 , and sigma VV 0 and the biophysical parameters are investigated and yield the following results. 1) The above-ground biomass-sigma 0 curves saturate above 50 tons/ha for sigma VV 0 , 100 tons/ha for sigma HH 0 , and over 100 tons/ha for sigma HV 0 when all forest species are included in the curves. 2) The sigma HH 0 -above-ground biomass curve for one forest species indicates a higher saturation level than that for the other forest species. Dependence on the forest species was absent for VV polarization and low for HV polarization. 3) A simple three-component scattering model indicates that volume scattering accounts for 80%-90% when the above-ground biomass exceeds 50 tons/ha. The surface-scattering components are up to ~20% for young stands, and the volume-scattering components are down to 70%. The origin of the dependency among the forest species was examined for the sigma HH 0 -above-ground biomass. It is concluded that a possible cause of the dependency is the different characteristics of the stands rather than forest species
Japanese Earth Resources Satellite 1 (JERS-1) synthetic aperture radar (SAR) data were evaluated to map areas of deforestation in a Brazilian Amazo/spl circ/nia test-site. The results were compared ...with information derived from a Landsat TM multitemporal series. Unambiguous detection of deforested areas was observed only when the entire deforestation process (slash, burning, and terrain clearing) had already occurred. This result recommends further investigations on the effectiveness of horizontal polarization SAR data to map deforestation in a consistent basis. The cross-polarized (horizontal-vertical) channel designed to be in the ALOS/PALSAR system is expected to improve the distinction between forested and recently deforested areas.
