BACKGROUND:Over the last two winters, there have been large-scale, unexplained losses of managed honey bee (Apis mellifera L.) colonies in the United States.In the absence of a known cause, this syndrome was named Colony Collapse Disorder (CCD) because the main trait was a rapid loss of adult worker bees.We initiated a descriptive epizootiological
Synechococcus sp.WH 8102 is a motile marine cyanobacterium isolated originally from the Sargasso Sea.To test the response of this organism to cadmium (Cd) -generally considered a toxin- cultures were grown in a matrix of high and low zinc (Zn) and phosphate (PO43-) and were then exposed to an addition of 4.4 pM free Cd2+ at mid-log phase and harves
Objective: To determine the incidence and types of congenital anomalies in neonates delivered at Songklanagarind Hospital Material and Methods: A retrospective study.Results: Among a total of 27,061 neonates delivered at Songklanagarind Hospital between January 1988 and December 1999, congenital anomalies were determined in 337 neonates.The overall
Large-size diffraction gratings have played an important role in modern scientific fields such as inertial us polo assn mens sweaters confinement fusion, large-aperture astronomical telescopes, and high-precision immersion lithography machines with long-stroke displacement stages.However, due to the large size and high accuracy requirements of grat
The traditional kinetics of electronically excited products of O3 and O2 photolysis is supplemented with the processes of the energy transfer between electronically-vibrationally excited levels O2(a1Δg, v) and O2(b1Σ+g, v), excited atomic oxygen O(1D), and the O2 molecules in the ground electronic state O2(X3Σg−, v).In contr
