Significant intravascular hemolysis can complicate dialysis (e.g., because of a kink in a dialysis line) and may result in the formation of methemalbumin (1 ). This gives serum a brown appearance, quite distinct from the typical reddish color associated with extravascular hemolysis. In this case, spectrophotometry performed before and after the addition of a reducing agent (sodium dithionite) (...

Condition on admission.?Patient, extremely jaundiced, corneal ulcer present in both the eyes. Tongue, dry and brown ; sordes on the lips and teeth. Patient apathetic and stupid. The liver dulness extended from the sixth interspace to just half an inch below the costal arch in the right nipple line. There was slight tenderness over the hepatic and epigastric regions. The diagnosis of the case on...

We have developed a new program called word_align for aligning parallel text, text such as the Canadian Hansards that are available in two or more languages. The program takes the output of char_align (Church, 1993), a robust alternative to sentence-based alignment programs, and applies word-level constraints using a version of Brown el al.'s Model 2 (Brown et al., 1993), modified and extended ...

Hot methane is found in many “cool” sub-stellar astronomical sources including brown dwarfs and exoplanets, as well as in combustion environments on Earth. We report on the first high-resolution laboratory absorption spectra of hot methane at temperatures up to 1200 K. Our observations are compared to the latest theoretical spectral predictions and recent brown dwarf spectra. The expectation th...

We report the detection of Hα emission in the T dwarf (methane brown dwarf) 2MASSW J1237392+652615 over three days using the Keck Low Resolution Imaging Spectrograph. The measured line flux, log(LHα/Lbol) = −4.3, is roughly consistent with early M dwarf activity levels and inconsistent with decreasing activity trends in late M and L dwarfs. Similar emission is not seen in two other T dwarfs. We...
