typically, best management practices (bmps) are implemented to help sustainable stormwater management in urban areas. over recent decades the selection of urban stormwater management measures for a site has been a challenge among urban planners where thecriterion based on flood volume no longer suffices for selecting urban drainage solutions. therefore there is a need to consider a set of holis...
In this study, a set of nitrogen reduction strategies were modeled to evaluate the feasibility of improving water quality to meet total maximum daily loads (TMDLs) in two agricultural watersheds. For this purpose, a spatial-process model was calibrated and used to predict monthly nitrate losses (1994-96) from Sand and Bevens Creek watersheds located in south-central Minnesota. Statistical compa...
* Corresponding author. USDA – ARS, SEWRL E-mail addresses: [email protected] (J. Cho), sm 1537-5110/$ – see front matter Published by doi:10.1016/j.biosystemseng.2009.01.011 Non-point source simulation models are commonly used tools for examining water and water quality issues. The dynamic agricultural non-point source assessment tool (DANSAT) is the distributed-parameter, physically-based, and cont...
State-approved forestry best management practices (BMPs) are a practice or combination of that, when properly implemented, effectively prevent reduce the amount nonpoint source (NPS) pollution entering waterbodies, such as sediment. Although BMPs voluntary in most states southeastern United States (U.S.), forest landowners operating under auspices certification system required to use BMPs, and ...
Agriculture is the world's second largest source of employment, often involving long hours and heavy work in challenging climates harsh conditions. The continued development sustainable intensive agriculture essential to maintain quality quantity agricultural products for consumers, particularly with scarcity natural resources, climate change, a growing world population physical limitation prod...
THE NEED FOR TARGETED AGRICULTURAL CONSERVATION The 2008 Gulf of Mexico Hypoxia Action Plan was developed in response to national water quality impairments that were largely caused by agricultural land uses within and around the US Corn Belt (Alexander et al. 2008; Mississippi River Watershed Nutrient Task Force 2008). plan prompted states create nutrient reduction strategies achieve a...
Efficacious bone regeneration could revolutionize the clinical management of many bone and musculoskeletal disorders. Bone morphogenetic proteins (BMPs) can regulate the differentiation of mesenchymal stem cells into cartilage, bone, tendon/ligament, and fat lineages. Early data documented the osteogenic potential of rhBMP2 and rhBMP7/OP-1. However, prior to this work that summarized several of...
Bone morphogenetic proteins (BMPs) are multi-functional growth factors belonging to the transforming growth factor ss superfamily. Family members are expressed during limb development, endochondral ossification, early fracture, and cartilage repair. The activity of BMPs was first identified in the 1960s but the proteins responsible for bone induction were unknown until the purification and clon...
Bone Morphogenetic Proteins (BMPs) are a group of signaling molecules that belongs to the Transforming Growth Factor-β (TGF-β) superfamily of proteins. Initially discovered for their ability to induce bone formation, BMPs are now known to play crucial roles in all organ systems. BMPs are important in embryogenesis and development, and also in maintenance of adult tissue homeostasis. Mouse knock...
The Bone Morphogenetic Protein (BMP) family reiteratively signals to direct disparate cellular fates throughout embryogenesis. In the developing dorsal spinal cord, multiple BMPs are required to specify sensory interneurons (INs). Previous studies suggested that the BMPs act as concentration-dependent morphogens to direct IN identity, analogous to the manner in which sonic hedgehog patterns the...
