Climate change uncertainty for daily minimum and maximum temperatures: a model inter-comparison
Several impacts of climate change may depend more on changes in mean daily minimum (T{sub min}) or maximum (T{sub max}) temperatures than daily averages. To evaluate uncertainties in these variables, we compared projections of T{sub min} and T{sub max} changes by 2046-2065 for 12 climate models under an A2 emission scenario. Average modeled changes in T{sub max} were slightly lower in most locations than T{sub min}, consistent with historical trends exhibiting a reduction in diurnal temperature ranges. However, while average changes in T{sub min} and T{sub max} were similar, the inter-model variability of T{sub min} and T{sub max} projections exhibited substantial differences. For example, inter-model standard deviations of June-August T{sub max} changes were more than 50% greater than for T{sub min} throughout much of North America, Europe, and Asia. Model differences in cloud changes, which exert relatively greater influence on T{sub max} during summer and T{sub min} during winter, were identified as the main source of uncertainty disparities. These results highlight the importance of considering separately projections for T{sub max} and T{sub min} when assessing climate change impacts, even in cases where average projected changes are similar. In addition, impacts that are most sensitive to summertime T{sub min} or wintertime …

Collection Plan Guidelines for Project Curators
This report is part of the Web-at-Risk project. These policy and planning documents typically guide collection management within libraries and archives. Some familiar concepts and practices from collection development for non-digital materials easily transfer to collection development for web-based materials while some new concepts and unfamiliar practices are introduced. To effectively manage web collections, it is good practice to either create new policies and plans or modify existing collection policies and plans.

Complete chloroplast genome of Trachelium caeruleum: extensiverearrangements are associated with repeats and tRNAs
Chloroplast genome structure, gene order and content arehighly conserved in land plants. We sequenced the complete chloroplastgenome sequence of Trachelium caeruleum (Campanulaceae) a member of anangiosperm family known for highly rearranged chloroplast genomes. Thetotal genome size is 162,321 bp with an IR of 27,273 bp, LSC of 100,113bp and SSC of 7,661 bp. The genome encodes 115 unique genes, with 19duplicated in the IR, a tRNA (trnI-CAU) duplicated once in the LSC and aprotein coding gene (psbJ) duplicated twice, for a total of 137 genes.Four genes (ycf15, rpl23, infA and accD) are truncated and likelynonfunctional; three others (clpP, ycf1 and ycf2) are so highly divergedthat they may now be pseudogenes. The most conspicuous feature of theTrachelium genome is the presence of eighteen internally unrearrangedblocks of genes that have been inverted or relocated within the genome,relative to the typical gene order of most angiosperm chloroplastgenomes. Recombination between repeats or tRNAs has been suggested as twomeans of chloroplast genome rearrangements. We compared the relativenumber of repeats in Trachelium to eight other angiosperm chloroplastgenomes, and evaluated the location of repeats and tRNAs in relation torearrangements. Trachelium has the highest number and largest repeats,which are concentrated near inversion endpoints or other rearrangements.tRNAs occur at …

Computational Fluid Dynamics Simulation of Fluidized Bed Polymerization Reactors
Fluidized beds (FB) reactors are widely used in the polymerization industry due to their superior heat- and mass-transfer characteristics. Nevertheless, problems associated with local overheating of polymer particles and excessive agglomeration leading to FB reactors defluidization still persist and limit the range of operating temperatures that can be safely achieved in plant-scale reactors. Many people have been worked on the modeling of FB polymerization reactors, and quite a few models are available in the open literature, such as the well-mixed model developed by McAuley, Talbot, and Harris (1994), the constant bubble size model (Choi and Ray, 1985) and the heterogeneous three phase model (Fernandes and Lona, 2002). Most these research works focus on the kinetic aspects, but from industrial viewpoint, the behavior of FB reactors should be modeled by considering the particle and fluid dynamics in the reactor. Computational fluid dynamics (CFD) is a powerful tool for understanding the effect of fluid dynamics on chemical reactor performance. For single-phase flows, CFD models for turbulent reacting flows are now well understood and routinely applied to investigate complex flows with detailed chemistry. For multiphase flows, the state-of-the-art in CFD models is changing rapidly and it is now possible to predict reasonably well …

A Consistent Prescription for the Production Involving MassiveQuarks in Hadron Collisions
This paper addresses the issue of production of charm orbottom quarks in association with a high pT process in hadron hadroncollision. These quarks can be produced either as part of the hardscattering process or as a remnant from the structure functions. Thelatter sums terms of the type (alpha_s log(pT/mq))n. If structurefunctions of charm or bottom quarks are used together with a hard processwhich also allows production of these quarks double counting occurs. Thispaper describes the correct procedure and provides two examples of itsimplimentation in single top and Drell-Yan at the LHC.

Consumer-Directed Health Plans: Early Enrollee Experiences with Health Savings Accounts and Eligible Health Plans
A letter report issued by the Government Accountability Office with an abstract that begins "Health savings accounts (HSA) and the high-deductible health insurance plans that are eligible to be coupled with them are a new type of consumer-directed health plan attracting interest among employers and consumers. Employers and plan enrollees may contribute to tax-advantaged HSAs, and enrollees can use the accounts to pay for health care expenses. Because HSAs and HSA-eligible plans are new, there is interest in the experiences of plan enrollees, as well as in comparing the plan features and enrollee characteristics with those of traditional plans, such as preferred provider organization (PPO) plans. GAO reviewed (1) the financial features of HSA-eligible plans in comparison with those of traditional plans, (2) the characteristics of HSA-eligible plan enrollees in comparison with those of traditional plan enrollees, (3) HSA funding and use, and (4) enrollees' experiences with HSA-eligible plans. GAO analyzed data regarding HSA-eligible and traditional plans and enrollees from national employer health benefits surveys, three selected employers, and a national broker of health insurance. GAO compared Internal Revenue Service (IRS) data for tax filers reporting HSA contributions with corresponding data for all tax filers under 65 years old. GAO …

Couples Magnetic and Structural Transitions in High-Purity Dy and Gd5SbxGe4-x
Magnetic materials exhibiting magnetic phase transitions simultaneously with structural rearrangements of their crystal lattices hold a promise for numerous applications including magnetic refrigeration, magnetomechanical devices and sensors. We undertook a detailed study of a single crystal of dysprosium metal, which is a classical example of a system where magnetic and crystallographic sublattices can be either coupled or decoupled from one another. Magnetocaloric effect, magnetization, ac magnetic susceptibility, and heat capacity of high purity single crystals of dysprosium have been investigated over broad temperature and magnetic field intervals with the magnetic field vector parallel to either the a- or c-axes of the crystal. Notable differences in the behavior of the physical properties when compared to Dy samples studied in the past have been observed between 110 K and 125 K, and between 178 K and {approx}210 K. A plausible mechanism based on the formation of antiferromagnetic clusters in the impure Dy has been suggested in order to explain the reduction of the magnetocaloric effect in the vicinity of the Neel point. Experimental and theoretical investigations of the influence of commensurability effects on the magnetic phase diagram and the value of the magnetocaloric effect have been conducted. The presence of newly found …
