Innovation and community action are two important strands for sustainable development. Yet they have not hitherto been linked. Community action is a neglected, but potentially important, site of innovative activity. Bridging this divide offers a novel theoretical approach to the study of community-level action for sustainability. The opportunities presented by grassroots innovation are discusse...

Low-income Hispanics are the most digitally underserved population in the U.S. This article examines the potential of community-based participatory research approach to e-health to decrease the disparities in access to technology and health information in low-income Hispanic communities. To demonstrate this framework, we describe the process of designing a community-based e-health intervention ...

Improved drilling and reservoir penetration efficiency is directly related to the quality of mud used. The right choice type its components will preserve formation productivity, stability well walls reduce probability other complications. Oil gas operators use barite, less often siderite or hematite weighting agent as a component in composition muds for conditions increased pressure. But these ...

Amide coupling reactions can be used to synthesize bispyridine-based ligands for use as bridging linkers in multinuclear platinum anticancer drugs. Isonicotinic acid, or its derivatives, are coupled to variable length diaminoalkane chains under an inert atmosphere in anhydrous DMF or DMSO with the use of a weak base, triethylamine, and a coupling agent, 1-propylphosphonic anhydride. The product...
