The Culture of Narcissism Revisited: Transformations of Narcissism in Contemporary Psychospirituality

In this paper, I trace the debate over narcissism in deinstitutionalized and heavily psychologized spiritualities. First, I summarize how Sigmund Freud’s discussion with Romain Rolland about the “oceanic feeling” established the classical psychoanalytic view of mysticism as a regression to primary narcissism. Second, I review how Heinz Kohut’s radical reconceptualization of narcissism has played a seminal role in socio-cultural interpretations of modern psychologized spirituality. Third, I explore how a contemporary psychospiritual tradition, A.H. Almaas’s Diamond Approach, details the relationship between narcissism and mysticism. Finally, I reflect on the benefits of a dialogical approach between psychoanalysis and spirituality arguing that the types of integrative psychospirituality envisioned by Romain and developed more fully by Almaas have the potential to facilitate the mature transformation of narcissism.
Time variable osmotic pressures produced by coupled reactions as a possible cause of cell division.

It has been shown in a previous paper that coupled reactions may produce diffusion phenomena which are characterized by highly asymmetric distributions of concentrations in a spherical cell. Under certain conditions such diffusion fields are unstable, the asymmetries in concentrations tending to increase indefinitely. This results in an increase of asymmetrically distributed osmotic pressures which may eventually result in a division of a cell. Constriction without elongation, as in cleavage, is studied. The process of division is brought about in this case by ordinary osmotic pressure, and not by the diffusion drag forces.
The politics of prevalence.

In 1910, nearly 20% of children died from an infectious disease, and many more were left permanently impaired. Our grandparents experienced childhood mortality in their families and among their neighbors, and they never could have imagined the casual way in which we treat fever in a healthy child today because childhood mortality associated with fever is so rare. One way to interpret the increase in the number of chronic conditions in the United States is that, by the mid-20th century, the decrease in the numbers of deaths and serious morbidities gave us the luxury to unearth new types of morbidity. 5 Such is the fruit of our labors to improve living conditions, invent vaccines, and treat acutely ill children. Modern medicine has itself increased the number of children living with specific chronic conditions
A Comparison of Three Variations on a Standard-Setting Method.

The purpose of this study was to determine whether two variations on the typical Angoff group standard-setting process would produce sufficiently consistent results to recommend their use. Judgments obtained from a group of experts during a meeting were compared with judgments gathered from the same group before and after the meeting. The results indicate that differences between passing scores obtained with the three variations are relatively small, but those gathered before the meeting were less consistent than ratings gathered during and after the meeting. These results imply that judgments gathered after an initial traditional group-process session can provide an efficient alternative mechanism for setting cutting scores using the Angoff method. This research was supported by The American Board of Internal Medicine, but does not necessarily reflect its opinions or policies.
Cellular calibrators to quantitate T-cell receptor excision circles (TRECs) in clinical samples

T-cell receptor excision circles (TRECs) are circular DNA molecules formed during rearrangement of the T-cell receptor (TCR) genes during lymphocyte development. Copy number of the junctional portion of the δRec-ψJα TREC, assessed by quantitative PCR (qPCR) using DNA from dried blood spots (DBS), is a biomarker for newly formed T cells and absent or low numbers of TRECs indicate SCID (severe combined immunodeficiency) or T lymphocytopenia. No quantitation standard for TRECs exists. To permit comparison of TREC qPCR results with a reliable method for counting TRECs across different laboratories, we sought to construct a stable cell line containing a normal human chromosomal constitution and a single copy of the TREC junction sequence. A human EBV (Epstein Barr virus)-transformed B-cell line was transduced with a lentivirus encoding mCherry fluorescence, puromycin resistance and the δRec-ψJα TREC sequence. A TREC-EBV cell line, with each cell carrying a single lentiviral insertion was established, expanded and shown to have one TREC copy per diploid genome. Graded numbers of TREC-EBV cells added to aliquots of T lymphocyte depleted blood showed TREC copy number proportional to TREC-EBV cell number. TREC-EBV cells, therefore, constitute a reproducible cellular calibrator for TREC assays, useful for both population-based screening for severe combined immunodeficiency and evaluation of naive T-cell production in clinical settings.
The focal cone electroretinogram

Abstract The focal cone electroretinogram (ERG) in monkey retina has been examined with a 3 deg pulse of laser light (544 and 633 nm) centered on a 25 deg steady white rod saturating field. The stimuli were viewed simultaneously through a slit lamp and corneal contact lens. Cone ERGS were studied at different eccentricities from the fovea and compared with full-field corneal and intraretinal ERGS. The cone ERG is maximum at the fovea. There are two components to the on- ( b -wave) and off-( d -wave) response, one slower, more long wavelength sensitive and more foveally oriented than the faster response. This makes the foveal cone ERG slower and more longer wavelength sensitive than the perifoveal ERG. This difference disappears at high rates (> 20 Hz) of stimulation. The foveal cone ERG is larger and slower than that of more peripheral retina. The slowness appears to be due to a subcomponent of the response which is especially prominent in the fovea and has a slightly greater long wavelength sensitivity than the more peripherally generated ERG. It may depend on a unique difference in L-M cone bipolar systems or in L-M cone interactions that are more prominent near the fovea.
Coupling between carbon cycling and climate in a high-elevation, subalpine forest: a model-data fusion analysis.

Fundamental questions exist about the effects of climate on terrestrial net ecosystem CO2 exchange (NEE), despite a rapidly growing body of flux observations. One strategy to clarify ecosystem climate–carbon interactions is to partition NEE into its component fluxes, gross ecosystem CO2 exchange (GEE) and ecosystem respiration (RE), and evaluate the responses to climate of each component flux. We separated observed NEE into optimized estimates of GEE and RE using an ecosystem process model combined with 6 years of continuous flux data from the Niwot Ridge AmeriFlux site. In order to gain further insight into the processes underlying NEE, we partitioned RE into its components: heterotrophic (RH) and autotrophic (RA) respiration. We were successful in separating GEE and RE, but less successful in accurately partitioning RE into RA and RH. Our failure in the latter was due to a lack of adequate contrasts in the assimilated data set to distinguish between RA and RH. We performed most model runs at a twice-daily time step. Optimizing on daily-aggregated data severely degraded the model’s ability to separate GEE and RE. However, we gained little benefit from using a half-hourly time step. The model-data fusion showed that most of the interannual variability in NEE was due to variability in GEE, and not RE. In contrast to several previous studies in other ecosystems, we found that longer growing seasons at Niwot Ridge were correlated with less net CO2 uptake, due to a decrease of available snow-melt water during the late springtime photosynthetic period. Warmer springtime temperatures resulted in increased net CO2 uptake only if adequate moisture was available; when warmer springtime conditions led into mid-summer drought, the annual net uptake declined.
Effects of Public Speaking Trait Anxiety and Intensity of Speaking Task on Heart Rate During Performance

The extant research examining the relationship between public speaking trait anxiety and heart rate has produced mixed findings. Some studies observe only weak relationships, whereas others report significant relationships between these variables. H. J. Eysetick has maintained that the degree of relationship between traits and heart rate depends on the stress levels under which the respondents perform when heart rate data are collected. An inspection of the existing studies shows that, consistent with Eysenck's observation, the studies reporting relationships between public speaking trait anxiety and heart rate were conducted under relatively low-intensity conditions in comparison to those reporting no such relationships. In the present study, heart rates of both anxious and nonanxious speakers were measured under both high- and low-intensity conditions. Results indicated that (a) heart rates of anxious speakers were significantly higher than those of nonanxious speakers when both performed under low-intensity conditions, but (b) heart rates were not different for anxious and nonanxious speakers when performing in high-intensity environments. These results provide a reconciliation of the inconsistent research findings and partially support the extension of Eysenck's conceptualization to communication apprehension theory and research.
Growth and G1 arrest of sarcoma virus transformed cells in serum free media

Rous-sarcoma transformed BHK cells can be continuously cultured in a medium containing Eagle's Minimal Essential Medium, iron and biotin. The rate of cell multiplication increased when serine, or serine plus other non-essential amino-acids were added to the medium. With biotin deleted from the medium there is a reduction in DNA synthesis and most cells are blocked in G1.
X-ray speckles from an optical grating

We report a study of speckles produced by x rays of partial transverse coherence scattered from the surface of an optical reflection grating. This study reveals the presence of surface inhomogeneity that is undetectable with either laser (visible) light or transversely incoherent x rays. Qualitative analysis of the speckle patterns provides us with information on the surface morphology of the optical grating. The underlying order due to the periodicity of the grating enhances the detection of the x-ray speckles. The speckle patterns are obtained using a well-characterized partially transverse-coherent source (a secondary source) produced with an arrangement of slits and a focusing mirror in a synchrotron x-ray beamline. The degree of transverse coherence is measured and compared quantitatively with statistical optics predictions for the complex-coherence factor. {copyright} {ital 1998} {ital The American Physical Society}
Measuring Associative Strength: Category-Item Associations and Their Activation from Memory

Three measures of the strength of association between a category and members of the category were investigated: (a) a naming measure, in which the participants (93 undergraduates) were asked to list the members of a category and the listing order was assumed to reflect associative strength; (b) a latency measure, which assessed the latency to correctly identify specific items as members or nonmembers of a given category; and (c) a facilitation measure, in which the spontaneous activation of an item upon presentation of a category label as a prime was assessed by considering the extent to which the prime facilitated recognition of an initially degraded (visually obscured) item. The three measures correlated substantially, thus validating the naming and latency measures as reasonable approximations of the likelihood that a given item will receive activation in memory when the category is presented. Many of the constructs of interest to survey researchers can be viewed similarly as associations in memory, and the naming and latency measures can be fruitfully used in surveys; research attesting to the utility of naming and latency data is reviewed. The present research concerns the assessment of associative strength. Various measures of associative strength are examined, in the hope of establishing their validity as approximations of the likelihood that a given construct will be activated from memory upon presentation of the stimulus. After briefly reviewing evidence from the attitudes literature that illustrates the value of an associative perspective, we shall argue that many additional constructs of interest to survey researchers also may be fruitfully viewed as associations in memory. We will then report research aimed at validating two measures of associative strength that are sufficiently straightforward to be employed in a survey context. The measurement of associative strength is often an important goal of survey researchers, although usually not an explicit one. Surveys seek to identify what
Analgesia for Dying Infants Whose Life Support Is Withdrawn or Withheld

Objective. To determine the frequency of opiate analgesia administration to infants when life support is discontinued and to determine whether infant characteristics, such as birth weight and diagnosis, or the physician9s reasons for discontinuing life support influence either the decision to provide opioid agents or the dosages administered. Methods. We reviewed all 165 deaths in a 3-year period at a university-based level III intensive care nursery. Of the 121 deaths attributable to withdrawal or withholding of mechanical ventilation and/or extracorporeal membrane oxygenation, we ascertained whether opioid analgesics (morphine sulfate [MS] or fentanyl) were administered either concurrent with or after life-support withdrawal and at what doses. We examined whether these end-of-life practices varied according to birth weight, diagnoses, and the reasons documented by the neonatologist for discontinuing life support. Results. Opioid analgesia was provided to 84% of infants as their life support was either withheld or withdrawn. Infants with necrotizing enterocolitis and major anomalies or chromosomal disorders were more likely to be given opiates than infants with other diagnoses. Birth weight was not different for infants who received opiates compared with those who were not given opiates. Opioid analgesia was provided to all 18 infants for whom physicians documented the patients9 suffering as a reason to discontinue life support. Sixty-four percent of infants who received opiates were given doses in the usual pharmacologic range of 0.1 to 0.2 mg/kg MS. Of the 36 infants given more than 0.2 mg/kg MS, all but 2 were receiving ongoing treatment with opioid agents. Conclusions. In most cases of withholding or withdrawal of life support in critically ill infants, neonatologists provided opioid analgesia to these infants at the end of life, despite the potential respiratory depression of opioid agents in infants whose respiratory support is discontinued.
Thallium-201 myocardial scintigraphy in acute myocardial infarction and ischemia

Thallium-201 scintigraphy provides a sensitive and reliable method of detecting acute myocardial infarction and ischemia when imaging is performed with understanding of the temporal characteristics and accuracy of the technique. The results of scintigraphy are related to the time interval between onset of symptoms and time of imaging. During the first 6 hr after chest pain almost all patients with acute myocardial infarction and approximately 50% of the patients with unstable angina will demonstrate 201 Tl perfusion defects. Delayed imaging at 2–4 hr will permit distinction between ischemia and infarction. In patients with acute myocardial infarction, the size of the perfusion defect accurately reflects the extent of the infarcted and/or jeopardized myocardium, which may be used for prognostic stratification. In view of the characteristics of 201 Tl scintigraphy, the most practical application of this technique is in patients in whom myocardial infarction has to be ruled out, and for early recognition of patients at high risk for complications.
A medium-scale measurement of the cosmic microwave background at 3.3 millimeters

A system has been developed for making measurements of spatial fluctuations in the cosmic microwave background radiation, on an angular scale of 5 arcmin to a few degrees. The system consists of an off-axis Gregorian telescope with a nearly Gaussian response with FWHM adjustable from 20 to 50 arcmin, an SIS coherent receiver operating at 3.3 mm, and a pointing system capable of better than 1 arcmin rms stabilization. This paper reports on results from the system's first balloon flight in August 1988, and ground-based measurements made from the South Pole in December 1988. A portion of the South Pole data is used to place a 95-percent confidence level upper limit of Delta T/T less than 0.000035 for Gaussian sky fluctuations in the background radiation at 20-arcmin angular scale and a limit of Delta T/T less than 0.000033 on overall excess intrinsic sky noise. In addition, dust contamination in cosmic background radiation data is estimated using measurements of the Galaxy from this flight and a previous one, along with the IRAS 100-micron map. These anisotropy results give the most stringent limits on cold dark matter theories to date.
Growth responsiveness to prolactin and its loss in normal rat mammary cells in culture.

Abstract Growth response of mammary epithelial cells to hormones, particularly to prolactin, was studied by using a primary culture of rat mammary gland organoids. After allowing the cells to attach and spread on the surface of plastic culture dishes, the effect of hormones was tested by means of [ 3 H]-thymidine incorporation and autoradiography in a medium containing 1% fetal calf serum. In this system, prolactin showed a modest but significant growth-stimulatory activity (50% over control), and addition of insulin or hydrocortisone or both enhanced the growth stimulation of prolactin to a large extent. Growth stimulation caused by these hormones without prolactin was always significantly lower than that caused with prolactin. A dose-response study indicated that prolactin can stimulate growth at physiological concentrations. The maximum stimulation was observed at 1–5 (μg/ml. The growth-stimulatory effect of prolactin was decreased as the culture period was prolonged, and by the 4th day in culture the effect was no longer observed. In contrast, the stimulatory effect of insulin was constant over the 5-day culture period. Phosphoethanolamine, which has been shown to be a growth factor for some rat and human mammary carcinoma cells, showed 2-fold growth stimulation when added with prolactin, insulin or hydrocortisone. The stimulatory effect was again not observed in older cultures, as in the case of prolactin.
Tyrosine kinase activity is necessary for growth factor-stimulated rabbit type II pneumocyte proliferation.

ABSTRACT: Tyrosine kinases are important in the signal transduc-tion of a number of growth factors. As shown previously, transforming growth factor (TGF)-α stimulated proliferation of type II cells in vitro. The mitogenic effect of TGF-α could be blocked by the addition of the tyrosine kinase inhibitors genistein or tyrphostin. Tyrosine phosphorylation in type II cells exposed to growth factors was examined using an antiphosphotyrosine antibody. After addition of TGF-α, phosphorylation of a tyrosine protein with a molecular mass of 170 kD, presumed to be the epidermal growth factor receptor (EGF-R), peaked by 5 min, returning to baseline by 30 min. As expected, genistein or tyrphostin decreased the TGF-α -induced phosphorylation of the EGF-R. Addition of TGF-β resulted in no newly phosphorylated tyrosine proteins. TGF-β decreased the TGF-α -induced phosphorylation of the EGF-R. Previous work has shown that TGF-β blocks the TGF-α stimulation of type II cell proliferation. It appears that TGF-β interferes with TGF-α -induced phosphorylation of the EGF-R.
Eight chemical explanations of the Fleischmann-Pons effect

Abstract Eight possible explanations for the heat produced in the Fleischmann-Pons effect are examined with the various conservative assumptions concerning the quantities used. No individual explanation is sufficient to explain the heat produced. All of them together can only explain heat as much as 3 W cm −3 .
Selective labeling of a membrane peptide with 15N‐amino acids using cells grown in rich medium

Nuclear magnetic resonance spectra of membrane proteins containing multiple transmembrane helices have proven difficult to resolve due to the redundancy of aliphatic and Ser/Thr residues in transmembrane domains and the low chemical shift dispersity exhibited by residues in α-helical structures. Although 13C- and 15N-labeling are useful tools in the biophysical analysis of proteins, selective labeling of individual amino acids has been used to help elucidate more complete structures and to probe ligand–protein interactions. In general, selective labeling has been performed in Escherichia coli expression systems using minimal media supplemented with a single labeled amino acid and nineteen other unlabeled amino acids and/or by using auxotrophs for specific amino acids. Growth in minimal media often results in low yields of cells or expression products. We demonstrate a method in which one labeled amino acid is added to a rich medium. These conditions resulted in high expression (≥100 mg/L) of a test fusion protein and milligram quantities of the selectively labeled membrane peptide after cyanogen bromide cleavage to release the peptide from the fusion protein. High levels of 15N incorporation and acceptable levels of cross-labeling into other amino acid residues of the peptide were achieved. Growth in rich media is a simple and convenient alternative to growth in supplemented minimal media and is readily applicable to the expression of proteins selectively labeled with specific amino acids. © 2006 Wiley Periodicals, Inc.

Translating Bulk Measures of Capsid Assembly Progress into Insights on Fine-Scale Kinetics and Pathways

Virus capsid assembly has become a key model system for studies of complicated self-assembly processes, attracting considerable interest from the biophysical modeling community. Simulation methods have proven valuable for gaining insight into the space of possible kinetics and mechanisms of capsid assembly, but they have so far been able to say little about the assembly kinetics of any specific virus. It is not currently possible to directly measure the detailed interaction rates needed to parameterize a model and there is only a limited amount of experimental evidence of assembly kinetics available to constrain possible pathways, almost all of it gathered from in vitro studies of purified coat proteins. We have developed methods to address this problem that use data fitting algorithms to learn rate parameters consistent with both structure-based rule sets and experimental light scattering data on bulk assembly progress in vitro. Our method combines ideas from gradient-based and response-surface local optimization methods with a heuristic global search strategy to find parameter fits that can approximately reproduce experimental measures of assembly progress. We have applied these methods to data from three capsid systems - human papillomavirus (HPV), hepatitis B virus (HBV), and cowpea chlorotic mottle virus (CCMV) - with the resulting fits suggesting three very different assembly mechanisms. Work is continuing to refine the learned rate parameters and pathways and explore how these mechanisms might change when computationally translated into more realistic representations of the assembly environment in vivo in order to more accurately model the assembly of viral capsids in living cells.
Glucose metabolism and cardiac hypertrophy

The most notable change in the metabolic profile of hypertrophied hearts is an increased reliance on glucose with an overall reduced oxidative metabolism, i.e. a reappearance of the foetal metabolic pattern. In animal models, this change is attributed to the down-regulation of the transcriptional cascades promoting gene expression for fatty acid oxidation and mitochondrial oxidative phosphorylation in adult hearts. Impaired myocardial energetics in cardiac hypertrophy also triggers AMP-activated protein kinase (AMPK), leading to increased glucose uptake and glycolysis. Aside from increased reliance on glucose as an energy source, changes in other glucose metabolism pathways, e.g. the pentose phosphate pathway, the glucosamine biosynthesis pathway, and anaplerosis, are also noted in the hypertrophied hearts. Studies using transgenic mouse models and pharmacological compounds to mimic or counter the switch of substrate preference in cardiac hypertrophy have demonstrated that increased glucose metabolism in adult heart is not harmful and can be beneficial when it provides sufficient fuel for oxidative metabolism. However, improvement in the oxidative capacity and efficiency rather than the selection of the substrate is likely the ultimate goal for metabolic therapies.
An algebraic-analytic approach to nonnegative bases

Abstract Rothblum and, independently, Richman and Schneider have used a combination of graph-theoretic and algebraic approaches based on the Frobenius normal form of a matrix to show that if A is an n × n nonnegative matrix, then the generalized eigenspace of A corresponding to its Perron root ϱ( A ) has a nonnegative basis. Moreover, they showed that among the Jordan chains corresponding to ϱ( A ), A has a chain of maximal length consisting entirely of nonnegative generalized eigenvectors. In this paper we develop an algebraic-analytic approach to the proofs of these results which is based on the asymptotic behavior of the resolvent operator. The approach allows us to suggest an algorithm for computing a nonnegative basis.
Selling the American dream myth to black southerners: The Chicago defender and the great migration of 1915–1919

After the broken promises of reconstruction, African Americans looked towards the North as a place where their dreams could be fulfilled. From towns and farms they poured into northern cities in pursuit of the American Dream. The apex of this diaspora lasted from 1915–1919 and is referred to as “The Great Migration.” Literature dealing with this exodus is dominated primarily by economic determinism and socio‐emotional explanations. While both explanations supply valuable insights, both neglect the role of rhetorical discourse in constructing social reality. This study addresses that omission by showing that the Chicago Defender, a black, nationally distributed newspaper, sought to persuade discontented southern blacks to migrate to the North by waging a migration campaign that utilized the recurring themes found in the American‐Dream Myth.
Algorithms ror Designing Fault-Detection Experiments ror Sequential Machines

In this paper we present algorithms for designing fault-detection experiments for sequential machines with special emphasis on the case in which the machine does not possess a distinguishing sequence. The length of an experiment is reduced through: 1) identifying each state with its own unique input/output set rather than using a common set for all states; 2) utilizing overlapping of the required input/output sequences so that a portion of the experiment serves more than one purpose; and 3) verifying the reference condition in which the machine is placed at many points in the experiment by as short a locating sequence as possible. Important distinctions are made between locating sequences of the type introduced in previous work and those defined and used here.
Impact of a Surgical Pathway for the Postoperative Care of Children with Atrial Septal Defects

Impact of a Surgical Pathway for the Postoperative Care of Children with Atrial Septal Defects
Stimulus-presentation probability influences newborns' head orientation to sound.

Although newborn infants are capable of turning their heads toward laterally-presented sounds, the incidence of such responding varies across studies. Previous work suggests that as the probability of a laterally-presented sound increases head-turning performance improves. To test this “lateral-stimulus-presentation probability” hypothesis, we presented 30 alert newborns with a rattle sound from a lateral source on either 1/4, 2/4, or 3/4 of all sound trials. On remaining sound trials the rattle came from a loudspeaker located above the infant's head. For 12 infants all lateral trials were presented consecutively; these trials were spaced across the session for the other infants. The likelihood of correct head turning increased linearly as the lateral-stimulus-presentation probability increased. The distribution of lateral trials did not influence the incidence of correct head turning.
On a characterization of algebraic number fields with class number less than three

Abstract A well known theorem of L. Carlitz states that classical algebraic number fields have class number less than or equal to two if and only if any two factorizations of an algebraic integer into irreducible elements contains the same number of factors. We show that the same result holds using a somewhat weaker factorization condition. This leads to a characterization of Dedekind domains with class number less than or equal to three.
Durable, nonchanging, metal-dielectric and all-dielectric mirror coatings

Spectral measurements of dielectric multilayer coatings that are exposed to vacuum or high humidity indicate that ion-plate coatings are very stable and capable of retaining their spectral characteristics within the recording's linewidth, unlike conventional electron beam-deposited coatings. The deposition of dense, dielectric thin films improves the durability and survivability of optical coatings in hostile environments. Reactive low-voltage ion plating is identified as the most versatile deposition process, with the least problematic upscaling.
Effects of Steady Tip Clearance Asymmetry and Rotor Whirl on Stall Inception in an Axial Compressor

Effects of rotor centerline offset and whirl on the pre-stall and stall inception behavior of a high-speed tip-critical axial compressor were investigated. The observations were made using a circumferential array of unsteady pressure transducers. The maximum amount of rotor offset and whirl used in this investigation was 26% and 13% of the design axisymmetric tip clearance respectively. Measurements were conducted using transient throttle movements which quickly decreased the mass flow in the compressor until the onset of rotating stall. A second set of measurements used quasi-transient throttling starting from a mass flow about 0.5% larger than the stalling mass flow. These data were analyzed with the traveling wave energy method, visual inspection of the filtered pressure traces, and a two-point spatial correlation technique. For the uniform tip clearance case rotating stall occurred while the slope of the pressure rise characteristic was negative. As expected, the flow breakdown exhibited “spike” inception with no observable rotating disturbances in the pre-stall time period. The introduction of small levels of steady and unsteady tip clearance asymmetry did not significantly alter the time average performance of the stage; circumferential variations in pressure rise and flow coefficient were minimal and the stalling flow coefficient remained unchanged. However, significant short length-scale rotating disturbances were observed in both of these cases prior to stall inception. As in the symmetric tip clearance case, short length-scale disturbances initiated rotating stall in the non-uniform tip clearance experiments. The location of the generation of the incipient stall cells with respect to the non-uniform tip clearance was strongly effected by the rotor offset/whirl.Copyright © 2007 by ASME
Surgery in hematopoietic tumors

The role of surgery in the diagnosis of hematopoietic malignancies is undisputed. Many techniques to procure and examine representative tissue samples are recognized in identifying dogs and cats with these diseases. More sophisticated cytologic techniques not yet readily available would be helpful in implementing appropriate diagnostic, prognostic, and therapeutic approaches. Surgery has a limited role in the management of primary disease. The greatest limitation to surgical intervention is the systemic nature of most hematopoietic malignancies. Other limitations that can more realistically be overcome include early recognition of patients with extranodal lymphomas in Stage I disease, the increased use of surgery and radiation as adjunctive therapies for patients with regional disease, a more aggressive approach to the treatment of disease complications, and the implementation of promising experimental therapies in clinical patients of the future. The surgeon treating dogs and cats with hematopoietic malignancies must, as always, practice accepted principles of bacteriologic and oncologic asepsis and await further advances in veterinary medicine to integrate this discipline more completely with other modalities of therapy.
Passage of Corynebacterium aquaticum through membrane filters.

Cellulose ester and polycarbonate membrane filters were tested for sterilizing capability with a contaminant,Corynebacterium aquaticum, isolated from cell culture medium. This contaminant, often found in water supplies, routinely passes filters of the polycarbonate type, but not of the cellulose ester type.C. aquaticum grows slowly requiring 7 to 10 days incubation in BME at 37°C before turbidity develops. Cryptic contamination is potentially a serious problem with this organism.
High efficiency fuel cell based uninterruptible power supply for digital equipment

Abstract Eliminating the ac–dc converter (such as a computer's power supply), in a dc system when using a fuel cell based uninterruptible power supply (UPS), serves several primary functions. Firstly, it eliminates the need for a dc–ac inverter, and secondly, it eliminates a usually highly inefficient component—the power supply. Multiple conversions result in multiple inefficiencies. By replacing the computer's ac power supply with a high efficiency dc power supply capable of operating directly from a fuel cell – and thereby eliminating the inverter – the overall efficiency of the UPS can be increased by 50% or more. This is essential considering that the primary function of a fuel cell based UPS is long-term operation of the system, and poor efficiency equates to higher fuel consumption. Furthermore, inefficient systems have greater power demands, and therefore a larger fuel cell stack is needed to power them. At the present cost of fuel cell systems, this is a considerable problem. The easiest way to accomplish a direct dc UPS is to replace the computer's ac–dc power supply with a dc–dc power supply.
Managed security services: an emerging solution to security

Recent security breaches at ChoicePoint Inc., Lexis Nexis and Citicorp have again proven that the security administration is an important function within an organization. However, for some organizations, it is practically not possible to implement the security measures in-house due to lack of staff, expertise, technology, and time to attend the evolving security issues. Managed security services (MSS) can be the answer to their security needs. The paper is an overview of this evolving solution to the security. Companies are turning to managed security service providers for their security requirements. Managed security service providers (MSSP) are experts in security administration and provide a wide range of packages and services. The paper covers the different types of services offered by MSS providers. The paper discusses in detail benefits and risks associated with hiring a MSSP. Choosing a MSSP is a vital step and should be performed with due care. The paper provides some guidelines that a company could follow while choosing a provider and making a service level agreement with the provider. Finally, the paper covers ongoing management and review processes to assess the performance of a MSSP.
Dopamine receptor antagonists block the effect of Tyr-MIF-1 (Tyr-Pro-Leu-Gly-NH2) on the opiate form of footshock-induced analgesia.

Abstract Previous studies have shown that some of CNS actions of an endogenous peptide Tyr-MIF-1, are mediated by dopamine (DA) receptors. To study the effect of DA receptor blockade on the antiopiate properties of Tyr-MIF-1, the opiate form of footshock-induced analgesia was elicited in the rat. The nociceptive responses were determined using the hot-plate test (52.5°C). Intraperitoneal pre-treatment with haloperidol (500 μg/kg), SCH 23390 (150 μg/kg), or spiroperidol (150 μg/kg) potentiated the antinociceptive effect of the footshock and blocked the antagonistic action of Tyr-MIF-1 (200 μg/kg and 2.0 mg/kg). A dose of haloperidol too small to potentiate the antinociceptive effect of the footshock (100 μg/kg) was still able to block the action of Tyr-MIF-1 (200 μg/kg). The results suggest that activation of DA receptors mediates the antagonizing effect of Tyr-MIF-1 on the opiate form of footshock-induced analgesia in the rat.
Target identification performance of infrared imager models as a function of blur and sampling

An experiment has been performed at the U.S. Army's Night Vision and Electronic Sensors Directorate to fully test these models. The experiment imagery is intended to test the bounds of the models under which various blur and sampling is representative of the sensor in the task of target identification. The perception experiment is compared to the estimates of performance given by the various models. The model results are then compared and contrasted.
Centrality of visual product aesthetics, tactile and uniqueness needs of fashion consumers

The purposes of this study were to determine whether fashion consumer groups (fashion followers, fashion innovators, fashion opinion leaders and innovative communicators) differ in centrality of visual product aesthetics, consumers' need for uniqueness and need for touch, and to examine possible correlations among these variables. Fashion design and merchandizing students completed the following scales: Need for Touch, Consumers' Need for Uniqueness, Centrality of Visual Product Aesthetics, Measure of Fashion Innovativeness and Opinion Leadership plus demographic information. Innovative communicators had a greater need for uniqueness than followers and opinion leaders, but not than innovators. Fashion followers scored lower on Centrality of Visual Product Aesthetics than did innovative communicators, innovators and opinion leaders. There was no difference in Need for Touch among fashion consumer groups. Scores on Need for Touch were positively correlated with scores on Centrality of Visual Product Aesthetics and Consumers' Need for Uniqueness. Scores on Centrality of Visual Product Aesthetics were positively correlated with scores on Consumers' Need for Uniqueness. Scores on Fashion Innovativeness and Opinion Leadership were positively correlated with scores on Centrality of Visual Product Aesthetics and Consumers' Need for Uniqueness. Scores on Fashion Innovativeness and Opinion Leadership were not significantly correlated with those on Need for Touch. Fashion consumer groups did differ in centrality of visual product aesthetics and need for uniqueness, but not in need for touch.
Chemiluminescence spectra of the new molecules, NaF2 and NaCl2, and their implications for reaction dynamics

Abstract Emission spectra from dilute gas mixtures of Na with F2 and Cl2 have been measured and indentified as orginating from electronically excited NaF*2 and NaCl*2 emitting to stable ground states of these molecules. This is the first observation of molecules of this type which were predicted to be stable theoretically in the case of LiF2. The existence of these molecules indicates an attractive exit channel in M + X2 → MX + X reactions of alkali atoms with halogens.
THE EFFECT OF HYPOPHYSECTOMY, CRYPTORCHIDISM, ESTROGEN AND ANDROGEN UPON THE LEVEL OF HYALURONIDASE IN THE RAT TESTIS

THE presence of a “spreading factor” in testes of rats, rabbits and guinea pigs was first observed by Duran-Reynals (1928, 1929). Chain and Duthie (1939, 1940) demonstrated that the “spreading factor” is identical with an enzyme isolated from autolysates of Type II pneumococci by Meyer, Dubos and Smith (1937), and designated by the latter authors as hyaluronidase in view of its capacity to depolymerize hyaluronic acid. Subsequently the concentration of hyaluronidase in testes of rats placed under various experimental conditions has been studied by several investigators. Sprunt et al. (1939) noted a decrease of hyaluronidase concentration in rat testes after 45 days of cryptorchidism. Determinations of the enzyme were made by a biological method of assay—the “spreading reaction.” Utilizing a turbidimetric method of assay, Leonard et al. (1946, 1948) reported a decrease of the enzyme content in testes of hypophysectomized animals and in cryptorchid animals.
Drugs from the Sea: A Marine Sponge-Derived Compound Prevents Type 1 Diabetes

More than one million Americans have Type 1 diabetes. This disease--also known as autoimmune or juvenile diabetes--strikes children suddenly, makes them dependent on insulin injections for life, and carries the constant threat of devastating complications. While it can and does strike adults, nearly half of all new cases are diagnosed in children. A child is diagnosed with Type 1 diabetes every hour. Type 1 diabetes is caused by the inability of a person"s pancreas to produce sufficient amounts of insulin to control their blood sugar levels and sustain life. While insulin injections allow affected individuals to control their blood sugar and stay alive, it is not a cure nor does it prevent the devastating complications of this disease, which include kidney failure, blindness, amputations, heart attack, and stroke. In Type 1 diabetes, the body"s own immune system goes awry, attacking and destroying insulin-producing cells in the pancreas.
Hadroproduction of photons and leptons

We calculate the spectrum of lepton pairs produced in hadronic collisions to first order in ${\ensuremath{\alpha}}_{s}$ in quantum chromodynamics (QCD). We compare the results with the data and identify further experimental tests. We emphasize that the same QCD graphs which generate the transverse momentum of lepton pairs also yield real photons at high transverse momentum, and calculate the resulting cross sections.
Effects of feeding programme and feeder space change at photo-stimulation using maize- or wheat-based diet on growth and reproductive performance of female broiler breeders

Abstract1. This study was carried out to determine the effects of breeder feeding programme to 29 weeks of age, and feeder space change at photo-stimulation using two sources of grain on breeder hen reproductive efficiency and egg characteristics.2. Fast-feathering Cobb 500 pullet broiler breeders were housed in 16 pens of 81 females each during rearing, and fed on either maize- or wheat-based diet, formulated to have similar nutrient composition. Two feeding programmes, Fast and Slow, were used from 14 to 29 weeks of age. At 22 weeks of age, 69 females that represented the body weight (BW) distribution from each pen were placed in a layer house where feeder space either remained very similar (from 6.3 to 6.5 cm/female) or was increased (from 6.3 to 8.4 cm/female). Breeder growth performance, reproductive efficiency and egg characteristics were evaluated.3. Data were analysed as a 2 × 2 × 2 factorial design with diet type, feeding programme and feeder space change as the main factors. The main effects of ...
Tradeoffs of integrating real-time tracking into IGRT for prostate cancer treatment

This study investigated the integration of the Calypso real-time tracking system, based on implanted ferromagnetic transponders and a detector array, into the current process for image-guided radiation treatment (IGRT) of prostate cancer at our institution. The current IGRT process includes magnetic resonance imaging (MRI) for prostate delineation, CT simulation for treatment planning, daily on-board kV and CBCT imaging for target alignment, and MRI/MRS for post-treatment assessment. This study assesses (1) magnetic-field-induced displacement and radio-frequency (RF)-induced heating of transponders during MRI at 1.5 T and 3 T, and (2) image artifacts caused by transponders and the detector array in phantom and patient cases with the different imaging systems. A tissue-equivalent phantom mimicking prostate tissue stiffness was constructed and implanted with three operational transponders prior to phantom solidification. The measurements show that the Calypso system is safe with all the imaging systems. Transponder position displacements due to the MR field are minimal (<1.0 mm) for both 1.5 T and 3 T MRI scanners, and the temperature variation due to MRI RF heating is <0.2 degrees C. The visibility of transponders and bony anatomy was not affected on the OBI kV and CT images. Image quality degradation caused by the detector antenna array is observed in the CBCT image. Image artifacts are most significant with the gradient echo sequence in the MR images, producing null signals surrounding the transponders with radii approximately 1.5 cm and length approximately 4 cm. Thus, Calypso transponders can preclude the use of MRI/MRS in post-treatment assessment. Modifications of the clinical flow are required to accommodate and minimize the substantial MRI artifacts induced by the Calypso transponders.

Adolescent health in alameda county

A cross-sectional study of 194 adolescents in Alameda County, California, was performed to investigate health care behavior, personal adjustment, substance abuse, and medical and dental morbidity. A multivariate analysis of this sample using age, sex, ethnic group, and family type as independent variables was carried out. Females were less likely than males to have a regular place for medical care, and youths belonging to single parent families were less likely than those from intact families. Older adolescents, blacks and Hispanics used hospitals and clinics more frequently, while whites used private physicians more frequently than did other ethnic groups. Also blacks and Hispanics were less likely to have received recent dental care than whites. Levels of substance abuse were comparable to national levels, and increased significantly with age. Though overall medical morbidity was low, the study confirms previous findings of significant levels of dental decay particularly in black youth. A significant relation exists between less dental care and dental decay, though no such relation exists between medical care and medical morbidity. The study has potential implications for better preventive approaches to adolescent health care.
General Properties of q-Number Schwinger Terms

A systematic study of properties of $q$-number Schwinger terms in the algebra of currents is carried out on the basis of Lorentz covariance. It is found that these terms can be expressed by means of a second-rank Lorentz tensor. As an application, the existence of a covariant time-ordered product of two currents is proven for a wide class of Schwinger terms.
