Medicare: Sponsors' Management of the Prescription Drug Discount Card and Transitional Assistance Benefit

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) added a prescription drug benefit to the Medicare program, which became effective January 1, 2006. To assist Medicare beneficiaries with their prescription drug costs until the new benefit became available, the MMA also required the establishment of a temporary program, the Medicare Prescription Drug Discount Card and Transi… more

Public Service Announcement Campaigns: Activities and Financial Obligations for Seven Federal Departments

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Government-sponsored public service announcement (PSA) campaigns are prepackaged messages generally placed for free through various media to promote designated government activities, programs, or services. Although PSAs may be placed for free, PSA campaigns may still incur financial obligations for production. GAO was mandated to provide information about federal PSA campaign activities by a House Appro… more

Media Contracts: Activities and Financial Obligations for Seven Federal Departments

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The federal government contracts with public relations firms, advertising agencies, media organizations, and individual members of the media to provide, among other things, messages about its programs and services. As we have reported, there is a lack of accurate governmentwide information on these contracts. Seven federal departments account for nearly all the obligated federal dollars for public relat… more

Adventures in Laser Produced Plasma Research

Description: In the UK the study of laser produced plasmas and their applications began in the universities and evolved to a current system where the research is mainly carried out at the Rutherford Appleton Laboratory Central Laser Facility ( CLF) which is provided to support the universities. My own research work has been closely tied to this evolution and in this review I describe the history with particular reference to my participation in it.

Gamma-Ray Bursts Shower the Universe with Metals

Description: According to the results from a Livermore computer model, some of the small change jingling in your pocket contains zinc and copper created in massive gamma-ray bursts (GRBs) that rank as the most impressive light shows in the universe. Livermore astrophysicist Jason Pruet and his colleagues Rebecca Surman and Gail McLaughlin from North Carolina State University (NCSU) reported on their calculations in the February 20, 2004, issue of ''Astrophysical Journal Letters''. They found that GRBs from … more

Radiocarbon Based Ages and Growth Rates: Hawaiian Deep Sea Corals

Description: The radial growth rates and ages of three different groups of Hawaiian deep-sea 'corals' were determined using radiocarbon measurements. Specimens of Corallium secundum, Gerardia sp., and Leiopathes glaberrima, were collected from 450 {+-} 40 m at the Makapuu deep-sea coral bed using a submersible (PISCES V). Specimens of Antipathes dichotoma were collected at 50 m off Lahaina, Maui. The primary source of carbon to the calcitic C. secundum skeleton is in situ dissolved inorganic carbon (DIC). U… more

A computational study of tandem dual wheel aerodynamics and the effect of fenders and fairings on spray dispersion

Description: With the goal of understanding how to mitigate the safety hazard of splash and spray around heavy vehicles, a computational study of the aerodynamics and spray dispersion about a simplified trailer wheel assembly has been completed. A tandem dual slick (TDS) wheel model that neglects complex geometric features such as brakes, wheel bolts and wheel cutouts but with the same dimensions as an actual trailer wheel assembly was used . A detailed simulation of the wheels alone demonstrated that the f… more

The pleiotropic roles of transforming growth factor beta inhomeostasis and carcinogenesis of endocrine organs.

Description: Transforming growth factor beta (TGF-beta) is a ubiquitous cytokine that plays a critical role in numerous pathways regulating cellular and tissue homeostasis. TGF-beta is regulated by hormones and is a primary mediator of hormone response in uterus, prostate and mammary gland. This review will address the role of TGF-beta in regulating hormone dependent proliferation and morphogenesis. The subversion of TGF-beta regulation during the processes of carcinogenesis, with particular emphasis on its… more

Simulation of spray dispersion in a simplified heavy vehicle wake

Description: Simulations of spray dispersion in a simplified tractor-trailer wake have been completed with the goal of obtaining a better understanding of how to mitigate this safety hazard. The Generic Conventional Model (GCM) for the tractor-trailer was used. The impact of aerodynamic drag reduction devices, specifically trailer-mounted base flaps, on the transport of spray in the vehicle wake was considered using the GCM. This analysis demonstrated that base flaps including a bottom plate may actually wo… more

Allele-specific deposition of macroH2A1 in Imprinting Control Regions

Description: In the current study, we analyzed the deposition patterns of macroH2A1 at a number of different genomic loci located in X chromosome and autosomes. MacroH2A1 is preferentially deposited at methylated CpG CpG-rich regions located close to promoters. The macroH2A1 deposition patterns at the methylated CpG islands of several imprinted domains, including the Imprinting Control Regions (ICRs) of Xist, Peg3, H19/Igf2 Igf2, Gtl2/Dlk1, and Gnas domains, show consistent allele-specificity towards inacti… more

X-ray Induced Pinhole Closure in Point Projection X-ray Radiography

Description: In pinhole-assisted point-projection x-ray radiography (or ''backlighting''), pinholes are placed between the sample of interest and an x-ray source (or ''backlighter'') to effectively limit the source size and hence improve the spatial resolution of the system. Pinholes are generally placed close to such x-ray backlighters to increase the field-of-view, leading to possible vaporization and pinhole closure due to x-ray driven ablation, thereby potentially limiting the usefulness of this method.… more
