Rapid blight is a new disease of cool season turf grasses caused by Labyrinthula terrestris. It is problematic in Arizona and ten other states in cool season turfgrasses at sites with elevated salinity of soil and/or irrigation water. L. terrestris colonizes Tifgreen bermudagrasses in the field, but causes no apparent disease. Laboratory trials have shown that as concentrations of sodium chlori...

In this work, poly (o-Anisidine) (POA) was prepared by consecutive potential cycling in an acidic monomer solution at the surface of Carbon Paste Electrode (CPE). Nickel ions were dispersed into the polymer by immersing the electrode in NiSO4 solution. The prepared Ni/POA/CPE was characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, Atomic Force Mic...

Primary organic aerosol (POA) and associated vapors can play an important role in determining the formation and properties of secondary organic aerosol (SOA). If SOA and POA are miscible, POA will significantly enhance SOA formation and some POA vapor will incorporate into SOA particles. When the two are not miscible, condensation of SOA on POA particles forms particles with complex morphology....

Treatment with testosterone (T) or estradiol (E2) facilitates intraspecific aggressive behavior in adult rodents. Brain aromatization of T to E2 appears to be involved in facilitation of fighting behavior. In the present study we measure the in vitro brain aromatase activity (AA) in the preoptic area (POA), amygdaloid nuclei (Am), ventromedial hypothalamus (VMH), and parietal cortex (CTX) from ...

For the quantitative measurement of pancreatic oncofetal antigen (POA), an enzyme immunoassay for POA has been developed, and is based on the sandwich method using antibody-coupled glass beads and enzyme (peroxidase)-labelled antibody. Serum POA concentrations were increased significantly in patients with pancreatic cancer, but not in those with chronic pancreatitis or other miscellaneous disea...

BACKGROUND AND AIMS Poa subgenus Poa supersect. Homalopoa has diversified extensively in the Americas. Over half of the species in the supersection are diclinous; most of these are from the New World, while a few are from South-East Asia. Diclinism in Homalopoa can be divided into three main types: gynomonoecism, gynodioecism and dioecism. Here the sampling of species of New World Homalopoa is ...

The low productivity of pastures and its sharp fluctuations in the desert regions Central Asia are due to natural-historical factors this natural zone. However, recent years, these shortcomings have been further aggravated as a result rapid growth population, continuous development industry transport areas, pressure anthropogenic man-made on vegetation soil is increasing from year year. This ca...
