“…These classes were highly related to the organic matter content and therefore to the land use insofar as organic matter content is lower in cultivated lands than in natural areas (forests, permanent pastures). Lal (1996) reported an increase in dry bulk density when forest was replaced by cultivated lands, which is consistent with our findings.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The mean bulk density value for the 0‐ to 5‐cm depth for Nigeria is 1.28 g cm −3 . This value is within the bulk density range for similar depth intervals reported by Lal (1996) for cultivated soils following deforestation in southwest Nigeria but lower than bulk density range reported for surface soils in bare and cultivated fields of Samaru in northern Nigeria (Lawes, 1965). Bulk density values (0–5 cm) in the regions around Sokoto and Maiduguri are higher than for other regions in Nigeria.…”

“…Contrary to this, Shepherd et al (2000) observed no effect of land-use systems on soil particle size distribution, because all soils under vegetation were of similar type. The closeness of our results to those of Lal (1996) could be due to similar soil type and ecosystems. The different results of Shepherd et al (2000) are due to the fact that their experiment was carried out in a different ecosystem and climate.…”
