Geometric modeling of river channel topography is a method design synthesis wherein specific 2D geometric elements topography, such as the bed profile, cross sectional shape, and planform contours, are expressed mathematically in isolation then combined to produce 3D heightmap. We utilized framework synthesize terrains that reveal flow-form-function linkages investigate what roles variability r...

Introduction: The Mars Exploration Rover Opportunity has traversed more than 13 km across Meridiani Planum, finding evidence of ancient aqueous environments that, in the past, may have been suitable for life. Meridiani bedrock along the rover traverse is a mixture in composition and bulk mineralogy between a sulfate-rich sedimentary rock and hematite spherules (" blueberries ") [1]. On top of t...

Abstract Histories of feminism in the past three decades have focused on debate between equal rights and separate spheres, but been less attentive to many strands socialist feminisms, which sought build bridges women's movement other social movements for freedom, equality justice. Dorothy Sue Cobble addresses this gap, exploring lives works democratic women activists relation versus debate. Ref...

Bullous ichthyosiform erythroderma (BIE) is a rare disorder of keratinization (mutations in either keratin 1 or 10). It typically presents with fragile skin, which gives way to gradual evolutionof hyperkeratosis. Flaccid blisters, peeling, and superficial erosions at sites of minor trauma or friction are apparent within the first few hours of life. Yellow-brown, waxy, ridged or corrugated...

In order to obtain a reasonable plan for synchronous grouting of the shield in anhydrous sandy cobble stratum, based on basic physical and mechanical characteristics stratum local construction conditions, material was selected, influence various factors mortar performance analyzed orthogonal experiments, multi-objective optimization carried out BP neural network genetic algorithm. The results s...

Between September 1996 and May 1998, the influence of habitat complexity and larval supply on the establishment of early post-settlement populations of red king crab (Paralithodes camtschaticus) was studied in situ in Auke Bay, southeast Alaska. Dive transects and suction dredge surveys conducted during fall 1996 and spring 1998 indicated that late age 0 to 1 1 red king crabs were located only ...

Facilitation cascades generated by co-occurring foundation species can enhance the abundance and diversity of associated organisms. However, it remains poorly understood how differences among native and invasive species in their ability to exploit these positive interactions contribute to emergent patterns of community structure and biotic acceptance. On intertidal shorelines in New England, we...
