The Army Corps of Engineers' Nationwide Permits Program: Issues and Regulatory Developments

Description: Permits issued by the U.S. Army Corps of Engineers authorize various types of development projects in wetlands and other waters of the United States. The Corps' regulatory process involves two types of permits: general permits for actions for private landowners that will likely have a minor effect on wetlands, and individual permits for more significant actions. Interest groups have a number of specific criticisms of the permits. For some time, there has been a stalemate in Congress over legisl… more

A STRUCTURAL IMPACT ASSESSMENT OF FLAWS DETECTED DURING ULTRASONIC EXAMINATION OF TANK 15

Description: Ultrasonic (UT) inspection of Tank 15 was conducted between April and July 2007 in accordance with the Tank 15 UT inspection plan. This was a planned re-inspection of this tank, the previous one was performed in 2002. Ten cracks were characterized in the previous examination. The re-inspection was performed to verify the present models and understanding for stress corrosion cracking. During this re-examination, one indication that was initially reported as a 'possible perpendicular crack <25… more

Stability of Galactic Gaseous Disks and the Formation of Massive Clusters

Description: We study gravitational instabilities in disks, with special attention to the most massive clumps that form because they are expected to be the progenitors of globular-type clusters. The maximum unstable mass is set by rotation and depends only on the surface density and orbital frequency of the disk. We propose that the formation of massive clusters is related to this largest scale in galaxies not stabilized by rotation. Using data from the literature, we predict that globular-like clusters can… more

Effects of vibrational motion on core-level spectra of prototype organic molecules

Description: A computational approach is presented for prediction and interpretation of core-level spectra of complex molecules. Applications are presented for several isolated organic molecules, sampling a range of chemical bonding and structural motifs. Comparison with gas phase measurements indicate that spectral lineshapes are accurately reproduced both above and below the ionization potential, without resort to ad hoc broadening. Agreement with experiment is significantly improved upon inclusion of vib… more

Measurement of |Vcb| and the Form-Factor Slope for BBar -> Dlnu Decays on the Recoil of Fully Reconstructed B Mesons

Description: We present a measurement of the CKM matrix element |V{sub cb}| and the form-factor slope {rho}{sup 2} for {bar B} {yields} D{ell}{sup -} {bar {nu}}{sub {ell}} decays based on 417 fb{sup -1} of data collected at the {Upsilon}(4S) resonance with the BABAR detector. The semileptonic decays are selected in B{bar B} events in which the hadronic decay of the second B meson is fully reconstructed. From the measured differential decay rate of the signal decay we determine G(1)|V{sub cb}| = (43.0 {+-} 1… more

Controversies over Redefining “Fill Material” Under the Clean Water Act

Description: On May 3, 2002, the Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (the Corps) announced a final rule redefining two key terms, “fill material” and “discharge of fill material,” in regulations that implement Section 404 of the Clean Water Act. This report discusses the revised rule, focusing on how it changes which material and types of activities are regulated under Section 404 and the significance of these issues, especially for the mining industry.

Chromatin condensation in terminally differentiating mouse erythroblasts does not involve special architectural proteins but depends on histone deacetylation

Description: Terminal erythroid differentiation in vertebrates is characterized by progressive heterochromatin formation, chromatin condensation and, in mammals, culminates in nuclear extrusion. To date, although mechanisms regulating avian erythroid chromatin condensation have been identified, little is known regarding this process during mammalian erythropoiesis. To elucidate the molecular basis for mammalian erythroblast chromatin condensation, we used Friend virus-infected murine spleen erythroblasts th… more

The Length of Time's Arrow

Description: An unresolved problem in physics is how the thermodynamic arrow of time arises from an underlying time reversible dynamics. We contribute to this issue by developing a measure of time-symmetry breaking, and by using the work fluctuation relations, we determine the time asymmetry of recent single molecule RNA unfolding experiments. We define time asymmetry as the Jensen-Shannon divergencebetween trajectory probability distributions of an experiment and its time-reversed conjugate. Among other in… more
