The redox dye 5-cyano-2, 3-ditolyl tetrazolium chloride (CTC) is used in aquatic sciences as a vital stain for enumeration of respiring bacteria in situ. Questions concerning its efficacy have been raised. We propose that the abundance of CTC-positive (CTC+) bacteria is a useful parameter in microbial ecology based on the...
While historiography and interest in Tudor England at both the popular and specialist levels presents few signs of diminishing, there may nonetheless exist a sense that we have little left to learn about this period and its culture. A notable gap in our knowledge, however, remains regarding the mysterious disease...
The growing urban development and the inadequate installation of settlements has caused environmental challenges such as landscape destruction, loss of urban tree biodiversity, therefore, the objective of this study was to identify the ecosystem services of urban trees in the 'Monumental Zone' of the city of Iquitos, in the Peruvian...
The La Ballena #3 site J69E is a shell midden located on Espiritu Santo Island in Baja California Sur. Archaeological excavations conducted in the summer of 2004 investigated a midden containing lithic and shell artifacts as well as faunal and human remains. Analysis of the debitage and formed lithic tool...
Soils of 49 agricultural and 2 "native condition" sites in the Lower Umatilla Basin,
Oregon were sampled for nitrate-nitrogen, ammonium-nitrogen, chloride, and pH
beginning in Fall of 1992. Several sites were sampled in Spring and Fall 1993 in order to
indicate movement or loss of residual soil nitrogen over time....
The use of edible coatings in combination with antimicrobial
agents enhances the microbial stability of foods. In this study we
evaluated the potassium sorbate and sorbic acid permeability of an
edible methylcellulose (MC) - palmitic acid (PA) film with a MC:PA
ratio of 3:1.
Permeability cell measurements were used to...
Through well designed tree placement, redundant use of simple technologies, and stewardship, trees grow. Over time, they mitigate stormwater flooding and enhance livability. This paper offers insights into precipitation patterns, and how small scale redundancy can help build the urban tree canopy. It is specifically geared toward issues in the...
The use of Boswellia tree’s fragrant resin, known as frankincense has been used in religious rituals and medicines for thousands of years. Those same uses have only increased in popularity throughout the world, and have made their way into western culture, where frankincense is a main ingredient in many skin...
Members of the deltocephaline leafhopper genus Giprus Oman
live on grasses, primarily in the desert-scrub, chaparral, and
marine sand dune communities of western North America. Of 16
known species, 10 are undescribed. Recharacterization of the genus
results in exclusion of Laevicephalus incongruus Oman. Differentiation
of species is primarily dependent on...
Advances of colloidal nanomaterials for societal benefit have been hampered by the high cost and low quality of nanoparticles (NPs). The production of high quality nanoparticles within colloidal suspension has two related concerns; (1) current high production rates methods of synthesizing nanoparticles result in a larger range of particle size,...
