• Baseflow: Baseflow is the water in a stream that is not directly associated with a specific precipitation events (i.e., event runoff). It is usually comprised of groundwater flow and slower shallow subsurface flow components including soil water drainage. • Drainage area/catchment/watershed: A watershed is the geographic area that contributes water to the same single point in a river or strea...

[1] A reduction in surface water quality in urban watersheds due to nonpoint source phosphorus (P) loading has prompted municipalities to consider management practices to reduce P loss from landscapes. However, locating P source areas can be time consuming and expensive. Use of distributed models allows delineation of P source areas and focused management strategies. Using the spatially distrib...

The development of a stain-resistant and pressure-stable textile is desirable for consumer and industrial applications alike, yet it remains a challenge that current technologies have been unable to fully address. Traditional superhydrophobic surfaces, inspired by the lotus plant, are characterized by two main components: hydrophobic chemical functionalization and surface roughness. While this ...

Headwater streams constitute the majority of stream length of river systems, and have important roles in terms of landscape processes and as habitat for organisms. These bodies of water are also tightly coupled with the local terrestrial landscape, making them ideal for studying linkages between land use and stream condition. Despite the ubiquity and importance of these streams, they are often ...

  The study seeks to address the importance of urban stream ecosystems from the perspective of urban ecology, human health and social well-being in the context of urban planning. The case study area is Paveh stream in the City of Paveh. The data from the case study area were gathered from questionnaire, existing scientific and library studies and by conducting interviews with residents and auth...

objective: infection control is one of the important aspects in dentistry. oral and maxillofacial surgery is one of the most sensitive fields in dentistry in which infection control is important a sterile surgical set is imperative. manufacturers only guarantee the sterility of the anesthetic not the sterility of its outer surface. they recommend alcohol to sterile the outer surface (especially...

Streams and forests are ecosystems connected through hydrology, but few studies have looked at the connectivity between streams in context of urban development. City-made decisions affect connections by isolating both ecosystems. often channelized or buried to increase potential development areas. Forests become fragmented may be removed unless protected. Historical choices land usage sites siz...
