The spinor representation is developed and used to investigate minimal surfaces in R with embedded planar ends. The moduli spaces of planar-ended minimal spheres and real projective planes are determined, and new families of minimal tori and Klein bottles are given. These surfaces compactify in S to yield surfaces critical for the Möbius invariant squared mean curvature functional W . On the ot...

To determine whether acridine orange (AO) staining of blood cultures could be used as a substitute for blind subculture when used in conjunction with the BACTEC system (Johnston Laboratories, Inc., Towson, Md.), the two methods were compared on all BACTEC-negative specimens. Since blind subcultures were routinely performed in our laboratory on days 2 and 6 of incubation, AO staining was also pe...

This has not been the general consensus throughout the twentieth century, however. Even in the late nineteenth century, there were those, mostly male physicians, who began to believe that infant feeding should be regulated by the clock. As artificial baby milk became all the rage in the twentieth century, both formulations of this milk and schedules to feed babies came into popularity. These sc...

Interactions between tethered layers composed of aggrecan (charged bottle-brush) macromolecules are responsible for the molecular origin of cartilage biomechanical behavior. To elucidate the role of the electrostatic forces in interaction between bottle-brush layers, we have performed molecular dynamics simulations of charged and neutral bottle-brush macromolecules tethered to substrates. In th...

OBJECTIVE Our goal was to test the hypothesis that infants who were breastfed more intensively during early infancy (< or = 6 months) will be less likely to have excess weight during late infancy (> 6 months) and to examine the independent impact of infant-initiated bottle emptying and mothers' encouragement of bottle emptying on infants' risk for excess weight. METHOD The sample consisted of...

This study evaluated the effect of water on dentin substrate bonding of one-bottle self-etching adhesives. Dentin substrates were divided into two groups: wet and dry dentin. Wet dentin is the normal substrate for bond testing whereas dry dentin was dehydrated in a desiccator for 24 hours. Bonded dehydrated teeth were then divided into two subgroups: stored in water or in desiccator for 24 hour...

Recently, one-bottle resins adhesives have been developed to reduce the number of clinical steps of resin application. They are now widely used in clinical dental practice. However, little is known regarding the detailed mechanism of bond degradation. Therefore, this study evaluated the durability of one-bottle resin adhesives using long-term water storage testing. Resin-dentin bonded specimens...

Excessive water production in the oil field is major difficulty for petroleum industry. Remedial techniques need to be applied control this excess considering health, safety, and environmental issues improve reservoir's economic productive life. In study polymer gel system comprising partially hydrolyzed polyacrylamide (PHPA) organic cross-linkers (Hydroquinone Hexamethylene tetramine) were pre...
