Recent studies have also shown that injection of CO2 into coal seams can enhance the production of coalbed methane (CBM), a more environmentally friendly fuel than oil. The Lower Cretaceous Mannville Group (Aptian-Albian) of southern Saskatchewan contains coals of subbituminous rank occurring within the Cantuar Formation. Because of their low economic importance, these coals have received only minimal attention in the past, and little is known of their distribution and character. A major project was recently initiated to assess the CO2 sequestration and CBM potential of the Mannville coals. Analysis of geophysical well logs, core, and drill cuttings was performed along with coal petrography in order to identify areas of the thickest, most extensive coal deposits, and to determine their petrographic characteristics. This report presents some...

Preferential attention to biological motion and faces is typically observed soon after birth (Johnson et al., 1991; Simion et al., 2008). The absence of this preference in toddlers and older individuals with autism may limit opportunities for social learning (Klin et al., 2009; Osterling & Dawson, 1994). Neural evidence suggests that infant siblings process faces relative to objects differently than low-risk infants by 10 months (McCleery et al., 2009). Orienting towards faces may support cortical specialization for social stimuli (Morton & Johnson, 1991). Objectives: The current study examines whether infant siblings orient to faces and low-level biological motion less than low-risk infants. Reduced orienting to social stimuli in infancy would restrict opportunities to learn about social interaction very early in the dev...

The data show that the silty interbeds of the upper sand-rich part of the cycle tend to have a ...

The order of mire types within the individual cycles allows an idealized mire type succession to be defined. The principle factor driving the idealized mire type succession is decreasing water depth within the peat-forming environment (terrestrialization), which leads to an increase in species diversity and a change in floral character from ferns→ angiosperms→ gymnosperms. Increases in water depth are the primary agent responsible for the termination of individual cycles in the ancestral Souris mire. Changes in nutrient status of the mire may also promote major changes in the floral assemblage, contributing to cycle termination. Comparison of densinite:ulminite ratios for the central part of the Souris seam shows an overall decrease in the degree of humification south-west...
