We have performed narrow-band imaging observations with the Very Large Telescope, aimed at detecting the Lyman continuum (LC) flux escaping from galaxies at z ∼ 3. We do not find any significant LC flux from our sample of two galaxies in the Hubble Deep Field South, at z = 3.170 and 3.275. The corresponding lower limits on the F1400/F900 flux density (per Hz) ratio are 15.6 and 10.2 (3-σ confid...

A basic objective of this study was t o evaluate the applicability of medium-resolution satellite radiation measurements to assessments of the diabatic heating and cooling within the atmosphere. Data from portions of TIROS I11 orbital passes in mid-July 1961 and concurrent conventional data were examined over a 4-by-4-degree grid scale. Computations, appropriate to analyzed cloud conditions for...

Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...

We assessed several methods of (13)C metabolic flux analysis (MFA) and found that isotopically nonstationary MFA achieved maximum flux resolution in cultured P493-6 B-cells, which have been engineered to provide tunable expression of the Myc oncoprotein. Comparison of metabolic flux maps obtained under oncogenic (High) and endogenous (Low) Myc expression levels revealed network-wide reprogrammi...

A new NIST luminous flux scale has been realized using the integrating sphere method, on which theoretical and experimental studies were previously conducted and reported. The NIST 2 m integrating sphere was modified to add an opening and an additional baffle to apply this method. Flux from an external source (1000 W quartz halogen lamp) is introduced into the sphere through a limiting aperture...

Bonanno, Joseph A., Yi Guan, Sergey Jelamskii, and Xiao Jun Kang. Apical and basolateral CO2-HCO3 2 permeability in cultured bovine corneal endothelial cells. Am. J. Physiol. 277 (Cell Physiol. 46): C545–C553, 1999.—Corneal endothelial function is dependent on HCO3 2 transport. However, the relative HCO3 2 permeabilities of the apical and basolateral membranes are unknown. Using changes in intr...

Short-term weathering rates (chemical denudation) of primary weathering products were derived from an analysis of fluxes in precipitation and streamwater. Rainfall, streamflow (runoff), and related water quality have been monitored at the Panola Mountain Research Watershed (PMRW) since 1985. Regression relations of stream solute concentration of major ions including weathering products [sodium ...

The warm tropical oceans underlie the most convective regions on earth and are a critical component of the earth’s climate, yet there are differing opinions on the processes that control warm pool SST. The Indo–Pacific warm pool is characterized by large-scale variations in SST approaching 308C on intraseasonal timescales. In this study, surface heat flux anomalies associated with composite war...
