The MOPITT (Measurement of Pollution in the Troposphere) instrument, to be launched on the Earth Observing System Terra platform, employs gas-correlation spectroscopy to measure profiles of tropospheric carbon monoxide and the total column of methane. The modeling of the instrument, and the associated radiative transfer, comprise the forward model employed in the retrieval calculations. The MOP...

ASK THE HEMATOLOGIST – Dr. John Hausdorff gives his take on the SPIKES protocol for conveying bad news. MINI REVIEW – Contributing Editor Dr. Omar Abdel-Wahab summarizes key findings related to histiocytoses. PRESIDENT’S COLUMN – Dr. Ken Anderson outlines six strategic priorities for the Society. PROFILES – Dr. Jack Hirsh reflects on a life devoted to hematology; mentee Dr. John Kelton pays tri...

We develop a method to calculate the column density distribution of the Lyα forest for column densities in the range 10 − 10 cm. The Zel’dovich approximation, with appropriate smoothing, is used to compute the density and peculiar velocity fields. The effect of the later on absorption profiles is discussed and it is shown to have little effect on the column density distribution. We introduce an...

In this work, the feasibility of a novel method cryogenic carbon capture based on dioxide frost deposition onto cold moving bed is explored. As gas mixture including CO2 flows through sufficiently packed bed, deposited material as frost. warmed by stream front advances bed. Experimental measurements rate advance within static are used to set up achieve continuous removal. Precooled and dry bina...

this paper focuses on using the recently developed extended finite element model for buckling analysis of edge cracked columns under concentric axial load. the effect of crack depth and its location on the carrying capacity of columns is studied. the effect of different boundary conditions is also investigated. numerical examples are offered to show the efficiency and effectiveness of the propo...

The trends and variability of ozone are assessed over a northern mid-latitude station, Haute-Provence Observatory (OHP: 43.93 N, 5.71 E), using total column ozone observations from the Dobson and Système d’Analyse par Observation Zénithale spectrometers, and stratospheric ozone profile measurements from light detection and ranging (lidar), ozonesondes, Stratospheric Aerosol and Gas Experiment (...

The Einasto profile has been successful in describing the density profiles of dark matter haloes $\Lambda$CDM N-body simulations. It also able to describe multiple components surface brightness galaxies. However, analytically projecting it calculate quantities under projection is challenging. In this paper, we will see development a highly accurate analytical approximation for mass (or counts) ...

Thermobaric convection (type II convection) and thermobaric cabbeling (type III convection) might substantially contribute to vertical mixing, vertical heat transport, and deep-water formation in the World Ocean.However, the extent of this contribution remains poorly constrained. The concept of ocean convective available potential energy (OCAPE), the thermobaric energy source for type II and ty...
