Using revenue management to improve pricing and capacity management in programme management

This paper presents revenue management models for pricing, capacity planning, and capacity reallocation and demonstrates their applicability for programme (project) management. In programme management, the allocation of capacity (resource time) to schedule activities requires the resolution of time versus revenue trade-offs. Thus, capacity planning and scheduling present a hierarchical problem for programme managers. Furthermore, current programme management methods do not consider the issue of price sensitivity exhibited in many programme management situations. Because of this omission, critical linkages between capacity management and scheduling of activities among programmes have not been addressed. Specifically, the issue of the reservation of capacity specifically for higher revenue generating activities has been omitted from programme management research. This paper asserts that, through capacity planning and scheduling, specific capacity should be reserved for customers willing to pay higher prices to have critical activities, for example, change orders, expedited. This capacity has scheduling effects that impact the programme NPV. This paper proposes potential solutions to capacity and programme scheduling problems using revenue management techniques.
OBSERVATIONS ON THE MORPHOLOGY AND SEXUAL REPRODUCTION OF COOLIA MONOTIS (DINOPHYCEAE)1

The surface morphology of the dinoflagellate Coolia monotis Meunier was compared with the surface morphology of Ostreopsis, The apical pore of C. monotis is similar in architecture to that of Ostreopsis but considerably longer (12 μm) than in O. heptagona (8–9 μm) and O. ovata (6–7 μm). A ventral pore in C. monotis is located on the right ventral margin between apical plate l′ and precingular plate 6″ and is similar in appearance and location to the ventral pore of O. ovata. The longitudinal flagellum (20 μm) in C. monotis is longer than in O. ovata (12 μ). Although Coolia and Ostreopsis appear to be distinctly different and should remain as two separate genera, they appear to be related. Cells of C. monotis divided by binary fission. Doubling time was 3–4 days in the logarithmic phase of growth at 23°C, 12:12 h L:D, 30–90 μE-m−2·s−1, and a salinity of 36%. Cultures reached cell densities of 2.5 × 103 cells·L−1 after 15 days of growth. The sexual process in C. monotis occurred in Erdschreiber's medium when Danish soil extract was substituted with mangrove sediment extract under the culture conditions described above. Gamete fusion produced large biflagellated planozygotes (70–75 μm diam). Planozygote maturation involved cytoplasmic reorganization, loss of motility, development of a spherical shape (80–90 μm diam), and two to three orange accumulation bodies. The cells at this stage appeared to be thin-walled cysts. Further development included reorganization of cyst contents, emergence of non-motile gametes, and development of chloroplasts, sulcus, and girdle. The nucleus of the newly formed cells occupied 50% or more of the total cell volume. Meiosis occurred in the cyst, but nuclear cyclosis was not observed. Four daughter cells were produced within 36–48 h, and motile gametes developed. The gametes exhibited sexuality for 2 months and completed the sexual life cycle by going through a thin-walled cyst stage.
Bacon‐Bercy Award To Hart

‘I was five years old when I first asked my mother about the lights in the night sky, and I haven't run out of questions yet.’ So says Helen Hart, the 1982 recipient of the June Bacon-Bercy Scholarship for Women in Atmospheric Sciences. A graduate student in the astrophysics department at the University of Colorado in Boulder, Hart earned her B.A. degree in 1981 with high honors in physics at the University of Montana in Missoula. Her research interests center on atmospheric structures and motions and on the developmental history o f the solar system. ‘I would like to study the effects of albedo changes over varying scale lengths on energy distribution and atmospheric dynamics,’ Hart said. Currently, she is a research assistant for the Voyager 2 photopolarimeter team at the Laboratory for Atmospheric and Space Physics at the university. She is working on using data on the polarization of scattered light to model the atmospheres of Saturn and its satellite,Titan.
Evaluation of a New Remote Sensing Method for Onboard Voltage Regulator in Computing System

Differential remote sensing has been popularly used in voltage regulator (VR) design for many years to ensure a high regulation accuracy requirement for processor supply voltage. One new remote sensing method by using normal VR controller is proposed in this paper to achieve similar high regulation accuracy as that by using true differential remote sensing method for output voltage. Working principles of the proposed method are analyzed in detail for normal VR controller with individual ground and combined ground, respectively. Advantages, design considerations, and application constraints for it are analyzed in detail as well. Finally, test is conducted for normal VR controllers with individual ground and combined ground to verify its effectiveness.
Disambiguating Keyword Queries on RDF Databases Using "Deep" Segmentation

Keyword search on (semi)structured databases is an increasingly popular research topic. But existing techniques do not deal well with the problems presented by the queries that are ambiguous. Recent approaches for RDF databases try to improve the quality of results by introducing an explicit top-k “interpretation” phase in which queries are translated into an ordered list of “most likely intended” structured (SPARQL) queries before query execution. However, even these recent techniques only address keyword query ambiguity in a limited fashion by identifying fine-grained semantic units or segments of a query. This enables some reduction in the space of interpretations, pruning away incorrect interpretations, but the reduction in interpretation space is not as aggressive as it could be. In this paper, we propose a “deep segmentation” technique for keyword queries issued against an RDF database. This approach achieves a more aggressive pruning of irrelevant interpretations from the space of interpretations considered and therefore produces better quality query interpretations even in the presence of significant query ambiguity. We present results for a comprehensive human-based evaluation that is based on a metric that we introduce called degree of ambiguity (DOTA) that has not been considered by previous efforts. The experimental results show that our approach outperforms existing techniques in terms of quality even when queries are very ambiguous.
Coronary vasospasm leading to an acute myocardial infarction after the administration of dolasetron

The 5-hydroxytryptamine antagonists are commonly used agents for the treatment of postoperative nausea and vomiting. However, these drugs can have significant cardiovascular adverse effects. We report a case of acute myocardial infarction after administration of dolasetron in a 17-year-old adolescent girl during strabismus corrective surgery.
Holographic polymer-dispersed liquid crystal sample characterization

Holographically formed polymer dispersed light crystal (HPDLC) materials have the potential to enable creation of a full motion video rate reflective display technology with excellent color, contrast, reflectance and good power efficiency. Current HPDLC display research focuses on the improvement of angular viewability and reduction of the drive voltage. Measurements of HPDLC devices have begun at AFRL to verify and expand measurements made by dpiX LLC. Specular and diffuse reflections are examined in terms of angular and spectral reflectance distributions. Presently reported measurements verify the ability of an HPDLC device to shift the reflected signal image away from the front- surface substrate specular angle (source image glare) by some 10 degree(s) and to expand the spread of the reflected signal image (full-width-half maximum) from a bout 1-2 degree(s) to 4- 10 degree(s) for a point illumination source under worst orientation conditions. Colors were stable over 20 degree(s) of viewing angle. Potential defense applications include replacing paper in cockpits and crewstations.
Cognitive, Interest, and Personality Variables Predicting First-Semester GPA:

124 freshmen entering engineering were administered the College Major Interest Indicator, Adjective Checklist (personality), Ship Destination Test (symbolic reasoning), and the Logical Reasoning test (verbal reasoning) to identify what combination of variables would best predict the first semester's GPA. Scores on these tests along with SAT-Verbal and Mathematics scores were used in a series of multiple regression analyses. Personality test scores alone were the best predictors of GPA (r = .78).
Laminar Fluid Flow in a Planar 90 Degree Bifurcation With and Without a Protruding Branching Duct

The laminar flow field in a planar, ninety degree bifurcation is examined. This numerical study uses the computational-fluid-dynamics software Fluent Version 4.11. First, the velocity field in a bifurcation without a protruding branching duct is modeled, and the results are successfully compared to experimental data. Next, the flow field is studied in bifurcations that have branching ducts that protrude into the main duct. The velocity field and pressure drop are documented, and are found to be strongly influenced by the extent of the branching duct protrusion.
Multiple subpial cortical transection (MST) for the treatment of extensive seizure foci

Multiple subpial transection (MST) was used to treat 7 patients who had intractable epilepsy with extensive seizure foci involving more than one lobe and both hemispheres, and who have had a follow-up of at least 2 years. The longest follow-up is 61 months, with a median of 43 months. Preoperative investigations included magnetic resonance scans, positron emission tomography scans, single photon emission computed tomography scans, and video-EEG monitoring with scalp and subdural electrodes. Two patients' seizure foci were in both hemispheres, and 5 patients' foci were in 2 lobes of 1 hemisphere. The motor cortex was involved in 5 patients and the speech areas in 1 patient. MST at an interval of 4 mm was performed over all areas that showed seizure foci. Two patients are free of seizures, 1 patient is free of seizures involving the operated hemisphere, 1 has rare seizures, 1 has >90% reduction in seizure frequency, 1 has >70% reduction in seizure frequency, and 1 did not respond to MST. MST alone was able to control seizures to varying degrees, without producing a permanent deficit, in 84% of patients with intractable seizures originating from large areas of the cortex.
Using echo to evaluate patients with left ventricular assist devices (LVADs): adding non-invasive PVR into the diagnostic toolbox.

In the midst of a striking decline in cardiovascular death rates in the United States, heart failure is fast becoming a major public health problem. Heart failure afflicts 400,000 to 700,000 new patients per year. While the causes of this epidemic are multifactorial, treatment advances are partly responsible. In the immortal words of N. W. Goodman, ‘‘we rescue people from a relatively sudden death from myocardial infarction only to inflict on them a more prolonged death from progressive heart failure.’’ Medical science helped to create the problem, but has also crafted a highly effective treatment for end-stage heart failure – heart transplantation – which ameliorates symptoms and prolongs life. Unfortunately, we can reach into the supply cabinet for only about 2,200 hearts for US patients each year, a number which has been remarkably stable, even as demand rises. But even before the widespread adoption of heart transplantation, the medical workbench was occupied with a more mechanistic solution. The total artificial heart program brought millions of dollars and days of front-page press coverage. Though beset by high-profile setbacks, the development of a total artificial heart continues, albeit with considerably less fanfare. In recent years, developments in ‘‘heart replacement therapy’’ have focused on ventricular assist devices (VADs). VADs include left ventricular (LV) assist devices (LVADs), right ventricular (RV) assist devices (RVADs), and RV and LV assist devices (BiVADs). A detailed discussion of the many different types of VADs is beyond the scope of this editorial. Briefly, most modern LVADs consist of an inflow cannula placed in the LV apex or the left atrium (the former is much more common because of the tendency toward LV clot formation with left atrial cannulation), connected via tubing to a pump with valves. A separate tube connects the pump with the outflow cannula, usually placed in the ascending aorta. The pumps come in two general varieties: pulsatile and axial (continuous) flow. Pulsatile pumps can trigger off of a time sequence or off of filling. In the early-generation LVADs, the pump was outside of the body, but the newer LVADs are all intracorporeal, usually inserted in the upper abdomen. BiVADs remain extracorporeal and consist of the LVAD system, as described, along with a separate RVAD pump with cannulae in the right atrium and main pulmonary artery. The newest fully implantable LVADs are capable of producing around 10 L/min flow. There are now percutaneously placed LVADs that provide lower levels of support.
Bio-inspired resin acid-derived materials as anti-bacterial resistance agents with unexpected activities

Methicillin-resistant Staphylococcus aureus (MRSA), a complex of multidrug resistant Gram-positive bacterial strains, has proven especially problematic in both hospital and community-settings, resulting in increased mortality rates and hospitalization costs. Emergence of resistance even to vancomycin, the standard reference for MRSA treatment, builds up pressure for the search of novel alternatives. We report potent natural resin acid-based cationic antimicrobial compounds and polymers that exhibit surprising antimicrobial activity against a range of MRSA strains, yet are largely non-toxic against mammalian cells. Molecular dynamics simulations and dye-leakage assays with anionic phospholipid membrane mimics of bacteria demonstrate a membrane-lysing effect induced by unique fused ring structures of resin acids that may constitute the principal mechanism of action for selective lysis of bacterial cells over mammalian cells. Our antimicrobial materials are derived from an unlikely yet abundant natural source, and offer a novel alternative to currently-used approaches.
On the way to scholarship: From master's to doctorate☆

Progress in the discipline of nursing is predicated on the development of a community of scholars who have passion for substance. Nurse educators are challenged to develop programs and environments that stimulate and nurture scholarship. However, doctoral education that enhances scholarship encompasses more than coursework. Strategies for the development of scholarly doctoral education are discussed in this article.
Polycomb segment myeloid malignancies.

An unexpected revelation of cancer genome studies has been frequent abnormality in genes for factors that modify chromatin, underscored in this issue of Blood by reports from Score et al and Kroeze et al of inactivating mutations and chromosome loss in SUZ12 , EED and JARID2 in myelodysplastic
Computer-generated trauma management plans: comparison with actual care.

TraumAID is a computer-based decision aid that uses decision rules and logical deduction to generate management plans for the initial definitive management of injured patients; its use is currently confined to assessing penetrating thoracoabdominal injuries in nonpregnant adults. These management plans were compared to trauma center care in an American urban medical school hospital. The TraumAID program was available to trauma chief residents for patient care during the “golden hour.” Resulting changes in plans were documented by the residents. For 15 months the management plans for all applicable patients were documented serially, as were computer plans and outcomes. The sequential care and computer-generated care plans were then blinded and judged by three other trauma surgeons as to acceptability and preference. A consecutive series of 97 patients was evaluated. The residents used the computer for 40 cases during patient care. In 5 of the 40 cases, they altered their evaluation, diagnosis, or treatment; in none of these 5 was the alteration judged an error. Of the 97 patients, 10 had adverse outcomes, 2 of which were judged potentially avoidable, with unacceptable errors in management. TraumAID’s plans were acceptable for both. In 31 cases previously managed by the judges themselves, the TraumAID plans were preferred by the judge to the care he or she had provided, by a ratio of 25:6 (p<0.01). In a preliminary assessment, computer-generated, patient-specific protocols for the acute management of injuries were preferred to actual care previously given by the judges themselves and were associated with improved care and potential improvement in outcome.
Clinical Trials: Discerning Hype From Substance

The interest in being able to interpret and report results in clinical trials as being favorable is pervasive throughout health care research. This important source of bias needs to be recognized, and approaches need to be implemented to effectively address it. The prespecified primary analyses of the primary and secondary end points of a clinical trial should be clearly specified when disseminating results in press releases and journal publications. There should be a focus on these analyses when interpreting the results. A substantial risk for biased conclusions is produced by conducting exploratory analyses with an intention to establish that the benefit-to-risk profile of the experimental intervention is favorable, rather than to determine whether it is. In exploratory analyses, P values will be misleading when the actual sampling context is not presented to allow for proper interpretation, and the effect sizes of outcomes having particularly favorable estimates are probably overestimated because of "random high" bias. Performing exploratory analyses should be viewed as generating hypotheses that usually require reassessment in prospectively conducted confirmatory trials. Awareness of these issues will meaningfully improve our ability to be guided by substance, not hype, in making evidence-based decisions about medical care.
The development of hippocampal and dorsolateral pallial region of the cerebral hemisphere in fetal rabbits. V. Sixty millimeter stage, glial cell morphology

The structure of the cerebral hemisphere of the 60 mm rabbit embryo was studied with aniline and Golgi stains. Two types of neuroglial cells are present for the first time at this stage and are described in detail: (1) Young neuroglial cells are elongate cells whose smooth somata are connected to an arbor of fine porcesses by a peduncle of varying length. They appear to develop from freely arborizing spongioblasts as somata lose their attachment to the ventricular surface and migrate toward the cortical plate. This suggests that astrocytes will be formed at a later state from freely arborizing spongioblasts rather than from typical spongioblasts whose connection to the pia has atrophied. (2) Small glial cells are present at all levels above the matrix lamina. They have small, smooth somata and fine, mossy processes arising from a short trunk at one pole of the cell. Although their origin is unknown, their small soze suggests they arise directly from germinal cells rather than from freely arborizing spongioblasts. Lacking conclusive evidence of their identity, they are tentatively regarded as a primitive type of oligodendrocyte.
Spring Season Colorado Cyclones. Part I: Use of Composites to Relate Upper and Lower Tropospheric Wind Fields

Abstract A set of 70 cases of spring season Colorado cyclone events is used to form composites which describe the upper (300 mb) and lower (850 mb) tropospheric wind fields during the early stages of cyclone formation. The 70 cases are partitioned into those which persist beyond 72 h (developing) and those which fill after 24 h (nondeveloping). The developing sample reveals a well-defined 300-mb wind maximum embedded in a short wave trough which propagates eastward during the six time periods studied. However, the nondeveloping sample composite exhibits little structure to the 300-mb wind pattern. A subsample of the developing cases, chosen on the basis of the presence of a jet streak over the New Mexico-Texas area, shows a stronger 300-mb wind maximum. The 850-mb composites show southerly flow in the southern Great Plains in the two samples and the subsample. The developing sample and jet streak subsample exhibit a marked increase in 850-mb wind speed as the exit region of the 300-mb jet maximum propagat...
Gene replacement in Halobacterium halobium and expression of bacteriorhodopsin mutants

Abstract A gene replacement method has been developed to express bacteriorhodopsin mutants in the archaeon Halobacterium halobium. Selectable plasmids carrying the bacterioopsin gene (bop) were integrated at the chromosomal bop locus of H. halobium. Under nonselective conditions, recombinants were isolated that had lost the integrated plasmid and retained a single chromosomal copy of the bop gene. This approach was used to construct a bop deletion strain. By using this strain, recombinants were obtained that express wild-type bacteriorhodopsin and mutants known to be defective in proton translocation. The expressed proteins were purified in a membrane fraction similar to purple membrane and were characterized in this form. UV/visible spectra of dark- and light-adapted bacteriorhodopsin from wild-type and Asp-96 mutants were identical to those of purple membrane. Arg-82, Asp-85, and Asp-212 mutants had 10- to 50-nm red shifts in their absorption maxima and showed altered light adaptation. The proton translocation activity of the wild-type samples and purple membrane was comparable, whereas the mutants had 0-60% of wild-type activity. These results support earlier studies of proton translocation mutants expressed in Escherichia coli.
Biodegradation of guanidinium ion in aerobic soil samples

Abstract : Biodegradation of guanidinium can be rapid and extensive in soils at low concentrations. With increased loading, the fraction of input guanidinium decreases significantly. Higher concentrations will, however, degrade upon prolonged incubation. Guanidinium degradation can vary in different soils and can be stimulated by a carbon source. Keywords: Biodegradation, Mineralization, Guanidinium, Soils, Reprints.
β-(Trimethylsilyl)ethoxymethyl chloride. A new reagent for the protection of the hydroxyl group

Abstract Reactions of β-(trimethylsilyl)ethoxymethyl chloride with alcohols afford the corresponding ethers in high yield. Deprotection using n-Bu4NF in THF or HMPA cleanly regenerates the hydroxyl function.
Progesterone, administered before kainic acid, prevents decrements in cognitive performance in the Morris Water Maze

The nature of progesterone (P4)'s neuroprotective effects is of interest. We investigated effects of P4 when administered before, or after, kainic acid, which produces ictal activity and damage to the hippocampus, to mediate effects on spatial performance. The hypothesis was that P4, compared with vehicle, would reduce decrements in Morris Water Maze performance induced by kainic acid. Experiment 1: We examined the effects of kainic acid on plasma stress hormone, corticosterone, and progestogen (P4 and its metabolites) levels in plasma and the hippocampus after subcutaneous (s.c.) P4 administration to ovariectomized rats. Rats administered kainic acid had the highest corticosterone levels immediately following injection. P4 is 5α-reduced to dihydroprogesterone (DHP) and subsequently metabolized to 5α-pregnan-3α-ol-20-one (3α,5α-THP) by 3α-hydroxysteroid dehydrogenase. The regimen of P4 used produced circulating and hippocampal levels of P4, DHP, and 3α,5α-THP within a physiological range, which declined at 14 hours postinjection and were not altered by kainic acid. Experiment 2: The physiological P4 regimen was administered to rats before, or after, kainic acid-induced seizures, and later effects on water maze performance were compared with that of rats administered vehicle. Rats administered kainic acid had significantly poorer performance in the water maze (i.e., increased latencies and distances to the hidden platform) than did rats administered vehicle. Administration of P4 before, but not after, kainic acid prevented these performance deficits. Thus, these data suggest that a physiological regimen of P4 can prevent some of the deficits in water maze performance produced by kainic acid. © 2010 Wiley Periodicals, Inc.

Magnetic properties of epitaxial oxide heterostructures

Diluted Magnetic Semiconductors (DMS) are of great interest as injection sources for spin-polarized currents into semiconductors. Epitaxial devices have been synthesized with an intermediate spacer layer of the same semiconductor (zinc oxide, ZnO) used to produce the DMS material (ZnCoO) ensuring a homoepitaxial junction to help reduce the interface states and conduction mismatch. We observe a large magnetoresistance of about 32% in the devices at low temperatures. The present work suggests that spin polarized transport could be achieved with DMS materials acting as the source of injected spins into a non-magnetic host.
Parallel short-range molecular dynamics using the Ādhāra runtime system

Abstract We describe a parallel program for simulating molecular dynamics subject to short-ranged molecular interactions. The program uses a runtime system, Ādhāra, for atom definition, partitioning and distribution over the processors as well as dynamical load balancing between processors. A significant speedup is achieved by eliminating the usual test for the minimum image criterion, using conditional statements, that is applied to pairs of atoms during the force calculation. Instead, coordinates of boundary atoms are adjusted for the periodic boundary condition just before communication. The algorithm uses domain decomposition and the link-cell method as well as a neighbor list within cells. Benchmark simulations of systems with 864 and up to 5 000 000 atoms run on an Intel Paragon computer are described.
SMARTS - A spectrometer for strain measurement in engineering materials

A new spectrometer called SMARTS (Spectrometer for Materials Research at Temperature and Stress) has been commissioned at the Los Alamos neutron science center and entered the user program in August of 2002. Its design maximizes capability and throughput for measurements of (a) residual macrostrain in engineering components and (b) in situ loading. This paper describes some aspects of the instrument.
The effects of various cure cycles upon the viability of Bacillus subtillis var. niger spores within solid propellant.

Saturethane solid propellant was used in all tests. The spore inoculum was evenly distributed in the propellant. Samples weighing approximately 5 g were aseptically removed, placed into curing ovens, and exposed to cure temperatures. Initial tests were conducted at 82 and 93 C. Analysis of the obtained data indicated that the survivor curves were not linear. Exposure of the inoculated propellant samples to 93 C reduced the initial population to less than 0.01% in about 20 hours. At 82 C, approximately 168 hours were required for a similar reduction. Tests involving curing temperatures of 105 and 115 C were also conducted. It is pointed out that changes in the mechanism of spore inactivation due to chemical and physical changes in the propellant could account for the nonlinear survivor curves obtained.
Chandra monitoring and trends analysis: status and lessons learned

The Chandra X-Ray Observatory was launched in July, 1999 and has yielded extraordinary scientific results. Behind the scenes, our Monitoring and Trends Analysis (MTA) approach has proven to be a valuable resource in providing telescope diagnostic information and analysis of scientific data to access Observatory performance. We have created and maintain real-time monitoring and long-term trending tools. This paper will update our 2002 SPIE paper on the design of the system and discuss lessons learned.
Intranasal delivery of erythropoietin plus insulin-like growth factor-I for acute neuroprotection in stroke. Laboratory investigation.

Object Individually, the cytokines erythropoietin (EPO) and insulin-like growth factor–I (IGF-I) have both been shown to reduce neuronal damage significantly in rodent models of cerebral ischemia. The authors have previously shown that EPO and IGF-I, when administered together, provide acute and prolonged neuroprotection in cerebrocortical cultures against N-methyl-d-aspartate–induced apoptosis. The aim of this study was to determine whether intranasally applied EPO plus IGF-I can provide acute neuroprotection in an animal stroke model and to show that intranasal administration is more efficient at delivering EPO plus IGF-I to the brain when compared with intravenous, subcutaneous, or intraperitoneal administration. Methods The EPO and IGF-I were administered intranasally to mice that underwent transient middle cerebral artery occlusion (MCAO). Stroke volumes were measured after 1 hour of MCAO and 24 hours of reperfusion. To evaluate the long-term effects of this treatment, behavioral outcomes were assess...
Comparison of Morokuma and perturbation theory approaches to decomposition of interaction energy. (NH4)+…NH3

Abstract The interaction energy between NH 4 + and NH 3 is decomposed for a range of intermolecular separations within the context of a variety of basis sets including 6-31G ** , 6-31+G ** , and Sadlej polarization sets of type [5s3p2d/3s2p], including a set of f-functions as well. The electrostatic component dominates the interaction in all cases. At separations near the minimum or closer, the Morokuma second-order components (POL and CT) blow up. In contrast, Δ E SCF def , representing mutual polarization and orbital relaxation, is in good agreement with the induction energy computed via perturbation theory. Correction of the superposition error is noted to be important for this agreement and, indeed, for all components. In fact, following this correction, even the smaller sets provide accurate measures of the exchange term. The second-order correlation correction to the electrostatic interaction ϵ es 12 is computed and found to be fairly small. The dispersion energy embodied in ϵ disp 20 is considerably larger than the latter term and grows in proportion to the flexibility of the basis set.
Shockless acceleration of thin plates modeled by a tracked random choice method

A method for accelerating thin metallic plates to hypervelociti es has been proposed by G. McCall. In this method, a shock in a propellant generates a strong expansion wave that smoothly accelerates the plate. We have studied the hydrodynamics of this process in one dimension, both analytically and computationally. The metal was modeled as a stiffened gas, and the corresponding Riemann problem was solved. The asymptotic behavior of the solution was determined analytically. The one-dimensional random choice method, modified so that material boundaries are tracked and the spatial mesh is refined locally, was used to compute the flow; comparison with the asymptotic solution demonstrated its accuracy. With this method, shocks that form within the accelerating plate were accurately resolved, so that possible structural damage to the plate could be evaluated.

Estimation of gonad volume, fecundity, and reproductive stage of shovelnose sturgeon using sonography and endoscopy with application to the endangered pallid sturgeon

Summary Most species of sturgeon are declining in the Mississippi River Basin of North America including pallid (Scaphirhynchus albus F. and R.) and shovelnose sturgeons (S. platorynchus R.). Understanding the reproductive cycle of sturgeon in the Mississippi River Basin is important in evaluating the status and viability of sturgeon populations. We used non-invasive, non-lethal methods for examining internal reproductive organs of shovelnose and pallid sturgeon. We used an ultrasound to measure egg diameter, fecundity, and gonad volume; endoscope was used to visually examine the gonad. We found the ultrasound to accurately measure the gonad volume, but it underestimated egg diameter by 52%. After correcting for the measurement error, the ultrasound accurately measured the gonad volume but it was higher than the true gonad volume for stages I and II. The ultrasound underestimated the fecundity of shovelnose sturgeon by 5%. The ultrasound fecundity was lower than the true fecundity for stage III and during August. Using the endoscope, we viewed seven different egg color categories. Using a model selection procedure, the presence of four egg categories correctly predicted the reproductive stage ± one reproductive stage of shovelnose sturgeon 95% of the time. For pallid sturgeon, the ultrasound overestimated the density of eggs by 49% and the endoscope was able to view eggs in 50% of the pallid sturgeon. Individually, the ultrasound and endoscope can be used to assess certain reproductive characteristics in sturgeon. The use of both methods at the same time can be complementary depending on the parameter measured. These methods can be used to track gonad characteristics, including measuring Gonadosomatic Index in individuals and/or populations through time, which can be very useful when associating gonad characteristics with environmental spawning triggers or with repeated examinations of individual fish throughout the reproductive cycle.
Turbid bottom water layer and bottom sediment in the Seto Inland Sea

Measurement of the vertical distribution of total suspended matter (TSM) was carried out during summer throughout the Seto Inland Sea. TSM concentration near the bottom is influenced significantly by water movement and turbid bottom water is observed in all areas where median grain size (Mdφ) of the bottom sediment is more than 47gf. The high concentration of TSM near the bottom may be due to resuspension of the surface layer of bottom sediments. Comparison of the organic content of the resuspended matter with that of the bottom sediment shows that the resuspended matter contains more organic matter with a lower C : N ratio than the bottom sediment. The C : N ratio of the resuspended matter is similar to that of TSM in the surface layer of the water column. It is thought that TSM in surface waters sinks and settles on the surface of the bottom sediment. This deposited material is then easily resuspended in the water column by tidal currents before becoming permanently incorporated into the bottom sediment.
Novel synthesis technique for zinc-silicate phosphors

A novel but simple synthesis technique for producing improved zinc-silicate phosphors with improved efficiency and persistence control as well as tight and uniform particle-size distribution is described. Silicic acid powder with a predetermined range of particle sizes is first coated with a solution containing manganese and arsenic ions and very fine zinc-oxide powder (100 A) and then fired in a wet nitrogen furnace at 1180°+/-50 C for 15+/-5 minutes. This method eliminates grinding and produces P1- and P39-type phosphors with cathodoluminescence performance superior to commercial samples.
Finding the Way Home: The Dynamics of Partisan Support in Presidential Campaigns

The tendency for lukewarm partisans to “come home” is generally regarded as the chief dynamic of presidential campaigns, but little is known about what draws these voters closer to their party’s candidate. The pattern is often taken as prima facie evidence that campaigns activate partisanship, but there is little direct evidence that party identification (PID) exerts any greater influence on candidate preference late in the campaign than it had earlier. This study uses panel surveys from two elections to uncover the mechanisms that lead partisans home. It demonstrates that past research focused on the fall campaign has missed evidence for activation of PID, which occurs as the primary phase closes. It also demonstrates that under certain conditions activation of ideology plays just as important a role in bringing partisans home as activation of PID. These findings indicate that the process whereby partisans “come home” is multi-faceted and may have nearly as much to do with ideology as with party loyalty.

Comparisons of percolation segregation of multi-size and continuous mixtures at multiple strains and strain rates

Abstract Percolation segregation of fines in multi-size and multi-component mixtures was quantified and compared with continuous mixtures. In addition to size; shape and density also affect the number of multi-size components needed to predict the percolation of fines for continuous mixtures. Processing condition such as strain rate also played the role in determining number of components needed to predict the percolation of fines in continuous mixture.
β3-adrenergic receptor induction of adipocyte inflammation requires lipolytic activation of stress kinases p38 and JNK

Activation of beta-adrenergic receptors (AR) in adipocytes triggers acute changes in metabolism that can alter patterns of gene expression. This work examined the mechanisms by which activation of hormone sensitive lipase (HSL) induces expression of inflammatory cytokines in adipocytes in vivo and model adipocytes in vitro. beta3-AR activation in mice triggered expression of inflammatory genes CCL2, IL-6, and PAI-1, as well as endoplasmic reticulum (ER) stress markers GRP78 and CHOP. Pharmacological inhibition of HSL blocked induction of inflammatory genes, but not ER stress markers. Promoting intracellular accumulation of free fatty acids (FFAs) in 3T3-L1 adipocytes increased expression of inflammatory cytokines, whereas inhibiting ceramide synthesis partly blocked PAI-1 expression, but not IL-6. Induction of inflammatory markers in vivo and in vitro was preceded by phosphorylation of p38 and JNK, and inhibition of HSL prevented activation of these kinases. Experiments with pharmacological inhibitors of specific MAP kinases demonstrated the importance of p38 MAPK as a mediator of lipolysis-induced inflammation in vivo and in vitro. Together, these results demonstrate that FFAs liberated by HSL activate p38 and JNK, and p38 mediates pro-inflammatory cytokine expression in adipose tissue.
The Electrical Resistivity of the Two Phases of Sodium at Low Temperatures

At low temperatures the crystal structure of sodium changes by the martensitic mechanism from body-centred cubic to close-packed hexagonal. By measurements on specimens which partially transform on cooling and by measurements on specimens whose composition has been changed by suitable straining, the resistivity of the two phases has been approximately determined between 15 and 50 $^\circ$K. The hexagonal close-packed phase has a lower ideal resistivity than that of the body-centred cubic phase (by about 40% at 20 $^\circ$K), whereas the residual resistivity is effectively independent of the structure. Some theoretical implications are discussed.
Vortex shedding in high-speed compressor blade wakes

The wakes of highly loaded compressor blades are generally considered to be turbulent flows. Recent work has suggested that the blade wakes are dominated by a vortex streetlike structure. The experimental evidence supporting the wake vortex structure is reviewed. This structure is shown to redistribute thermal energy within the flowfield. The effect of the wake structure on conventional aerodynamic measurements of compressor performance is noted. A two-dimensional, time-accurate, viscous numerical simulation of the flow exhibits both vortex shedding in the wake and a lower-frequency flow instability that modulates the shedding. The numerical results are shown to agree quite well with the measurement from transonic compressor rotors.
Life History and Reproductive Biology of the Endangered Trillium reliquum

Knowledge of ecological characteristics of rare species is important in assessing their threat status. Trillium reliquum is one of four globally vulnerable North American Trillium species. Yet little is known about the ecology and reproductive biology of T. reliquum. Here we present the first description of the natural history and reproductive biology of T. reliquum. We observed the timing of emergence, flowering, fruit maturation, and seed dehiscence of a population in south-central Georgia (USA). In addition, we conducted a series of pollen manipulation experiments to assess the breeding system and pollen limitation. We found the life history of this species to be similar to other Trillium species; individuals progressed through four morphologically distinct life stages with increases in size and age. However, T. reliquum exhibited an earlier and shorter germination period than other Trillium species and many plants exist in a dormant state during the growing season. This species matured fruit equally well with either cross- or self-pollen and by apomixis. Seeds produced per fruit did not differ among reproductive treatments. The lack of differences in fruit and seed production among pollination treatments suggested there was no pollen limitation in 2004 for this population. The data we report here provide a baseline that can be used to generate assessments of the population stability of T. reliquum.
Reduced Friction Losses and Wear by DLC Coating of Piston Pins

A Diamond Like Carbon (DLC) coating is well known to offer superior wear and friction behaviour. This combination of properties makes DLC suitable for many different areas of tribology. This paper concerns itself with usage in the power cylinder environment of automotive diesel engines. To estimate the potential of DLC coatings applied to piston pins in internal combustion engines, linearly reciprocating sliding wear examinations have been performed on uncoated and DLC coated component segments versus different counterpart materials as present in the power cylinder environment, including: piston (aluminium alloy), bushing (brass), piston pin (steel) and connecting rod (steel). Evaluation criteria for the tests include friction and wear performance in dry and lubricated conditions. Test results show how the DLC coatings offer impressive wear reductions for each of the different counterpart materials used. Furthermore, special emphasis is given to the analysis of the friction behaviour. As expected, the coefficient of friction (COF) decreased for aluminium and steel counterparts when the piston pin segments were DLC coated. However, for the combination of DLC with brass the COF increased in the dry condition. This surprising outcome is explained with SEM and EDX investigations of the wear traces. The tests at elevated temperature with lubrication show an inverse relationship with respect to friction criteria when compared with the dry room temperature tests for the DLC with brass combination. Examined engine tests confirm the results of the non-engine wear test rig, showing that DLC coatings applied on piston pins also exhibit properties and good potential to decrease frictional losses and fuel consumption in modern engines.Copyright © 2008 by ASME
Programmed electrical stimulation and long-term follow-up in asymptomatic, nonsustained ventricular tachycardia

Abstract Thirty-three patients with ventricular tachycardia (VT) (3 or more beats, less than 30 seconds in duration, rate more than 100 per minute) on 24-hour Holter monitoring and no history of clinical arrhythmia (presyncope, syncope or sudden death) were studied using programmed electrical stimulation (PES). PES induced VT in 14 patients (42%), sustained VT in 7 (21%) and nonsustained VT in 7 (21%). Inducible VT was associated with underlying heart disease in 9 of 19 patients with coronary artery disease, 3 of 6 patients with idiopathic dilated cardiomyopathy and 2 of 4 patients with mitral valve prolapse. Patients without structural heart disease did not have inducible VT. Ejection fraction (EF) was not significantly different in patients with or without inducible VT. Twenty-three patients were discharged with drug therapy and 10 patients without therapy. At 23 ± 16 months (mean ± standard deviation) follow-up, 28 patients (85%) were alive, 4 (12%) had died from a cardiac cause (EF 49 ± 17% vs 28 ± 20%, p
