Changes in the current workforce of obstetrician–gynecologists and other health care providers of obstetric care, as well as changes in the delivery of health care services, prompt health care leaders to consider alternative strategies for approaching the essential shortage of obstetric care providers and facilities. Geographic variations in health care needs and resources require a tailored approach by individual communities and local health care providers. New and emerging technologies can support a range of innovative solutions to health care access limitations. This article describes an alternative model for remote obstetric care and quality review in Santa Fe, New Mexico, that is applicable to any community facing limited access to full-spectrum obstetric care.
The paper by Brush and Barghoorn demonstrates that fossil spores, as observed within the parent fructifications, matured at varying rates. This corroborates similar conclusions reached earlier by Moore.
Antibody binding capacity (ABC) is a term representing a cellapos;s ability to bind antibodies, correlating with the number of specific cellular antigens expressed on that cell. ABC allows magnetically conjugated antibodies to bind to the targeted cells, imparting a magnetophoretic mobility on each targeted cell. This enables sorting based on differences in the cell magnetophoretic mobility and, potentially, a magnetic separation based on the differences in the cell ABC values. A cellapos;s ABC value is a particularly important factor in continuous magnetic cell separation. This work investigates the relationship between ABC and magnetic cell separation efficiency by injection of a suspension of immunomagnetically labeled quantum simply cellular calibration microbeads of known ABC values into fluid flowing through a quadrupole magnetic sorter. The elution profiles of the outlet streams were evaluated using UV detectors. Optimal separation flow rate was shown to correlate with the ABC of these microbeads. Comparing experimental and theoretical results, the theory correctly predicted maximum separation flow rates but overestimated the separation fractional recoveries.
Every American president promotes improvements in science, technology, engineering and math education to enable American students to better compete in the global high tech economy; and employers want colleges to place more emphasis on such instruction. In fact, improved education in science and technology – well beyond basic computer skills – is vital to more than occupational competitiveness. As democratic citizens, Americans must understand science basics, including in frontier areas such as molecular biology and genomics, if they are to grasp the ways in which new technologies are profoundly transforming our lives. Unfortunately, a recent study concludes that more than 30% of Americans are effectively scientifically illiterate, so educators have a long ways to go.
The occurrence of massive reddish sandstones and quartzites lying between the Coal Measures and Carboniferous Limestone in the Bristol District has long been known. From their position and distinctive lithology, these beds have been referred to as the Millstone Grit by many early writers, amongst whom Austin (1865) may be mentioned. However, it has been shown that in part these beds are of Lower Carboniferous age. This was recognized by Vaughan (1905) notably in the Avon Section and at Long Ashton, where red grits and sandstones, previously regarded as Millstone Grit, were shown to represent horizon ∈, and later found by him to be of D3 age. Dr. Stanley Smith (1930) has shown at Wick, on the eastern border of the Bristol Coalfield, that the lower part of the red and gritty beds of that area are likewise of Avonian D3 age. Dr. Smith suggested a non-sequence between Lower and Upper Carboniferous to occur some 30 feet above a thin gritty limestone, the “Mollusca Band” of D3 age. Between this horizon and that from which Yorkian plants were recorded (Crookall in Smith, 1930, p. 342), some 350 to 400 feet of grits and micaceous shales occurred. These beds were of uncertain age, and Dr. Smith held the opinion that part and probably most of these beds belong to the Upper Carboniferous.
