Soil microorganisms are key drivers of terrestrial biogeochemical cycles, yet it is still unclear how variations in soil microbial community composition influence many ecosystem processes. We investigated how shifts in bacterial community composition and diversity resulting from differences in carbon (C) availability affect organic matter decomposition by(More)
The possible effects of soil microbial community structure on organic matter decomposition rates have been widely acknowledged, but are poorly understood. Understanding these relationships is complicated by the fact that microbial community structure and function are likely to both affect and be affected by organic matter quality and chemistry, thus it is(More)
Some of the earliest products commercializing nanotechnology could be drug delivery systems. Nanoparticle-based delivery systems would allow faster drug absorption into the human body and would have other unique properties minimizing side-effects. As companies seek to bring new therapies to market, there are certain to be a number of disputes over(More)
Fluids research often involves developing theories about the complex relationships between multiple scalar and vector quantities. We discuss strategies for effectively visualizing co-located vector fields, enabling the key physical structures of one vector field to be clearly understood within the context of a related vector field. We describe the range of(More)
We investigated the community structure of bacteria that populate the stomach of the Brumby, a breed of feral horses from the Australian outback. Using a 16S rRNA gene clone library, we identified 155 clones that were assigned to 26 OTUs based on a 99.0 % sequence identity cutoff. Two OTUs represented 73.5 % of clones, while 18 OTUs were each assigned only(More)
BACKGROUND Patients undergoing vascular surgery procedures constitute a 'high-risk' group. Fatal and disabling perioperative complications are common. Complications arise via multiple aetiological pathways. This mechanistic redundancy limits techniques to reduce complications that target individual mechanisms, for example, anti-platelet agents. Remote(More)
The Oklahoma Working Papers in Indigenous Languages focuses on issues related to Oklahoma Native languages and other indigenous languages of the Americas, but welcoming research done on any endangered indigenous language. OWPIL is committed to publishing research on all topics related to Native American languages, especially documentary and descriptive(More)
