At-home self-collection of saliva, oropharyngeal swabs and dried blood spots for SARS-CoV-2 diagnosis and serology: post-collection acceptability of specimen collection process and patient confidence in specimens.

Abstract Background Options to increase the ease of testing for SARS-CoV-2 infection and immune response are needed. Self-collection of diagnostic specimens at home offers an avenue to allow people to test for SARS-CoV-2 infection or immune response without traveling to a clinic or laboratory. Before this study, survey respondents indicated willingness to self-collect specimens for COVID-related tests, but hypothetical willingness can differ from post-collection acceptability after participants collect specimens. Methods 153 US adults were enrolled in a study of the willingness and feasibility of patients to self-collect three diagnostic specimens (saliva, oropharyngeal swab (OPS) and dried blood spot (DBS) card) while observed by a clinician through a telehealth session. After the specimens were collected, 148 participants participated in a survey about the acceptability of the collection, packing and shipping process, and their confidence in the samples collected for COVID-related laboratory testing. Results A large majority of participants (>84%) reported that collecting, packing and shipping of saliva, OPS, and DBS specimens were acceptable. Nearly nine in 10 (87%) reported being confident or very confident that the specimens they collected were sufficient for laboratory analysis. There were no differences in acceptability for any specimen type, packing and shipping, or confidence in samples by gender, age, race/ethnicity, or educational level. Conclusions Self-collection of specimens for SARS-CoV-2 testing and preparing and shipping specimens for analysis were acceptable in a diverse group of US adults. Further refinement of materials and instructions to support self-collection of saliva, OPS and DBS specimens for COVID-related testing is needed. Trial registration No intervention was tested in this study
Stevenson's sick children: A Child's Garden of Verses and the therapeutic imagination.

Growing up in the raw climate of 19th-century Edinburgh, Scottish author Robert Louis Stevenson (1850–1894, figure 1) was by his own admission a sickly child. Frequently afflicted by a confluence of maladies, he spent long hours confined to bed, listening to a medley of Highland legends, folk tales and narratives of Scottish religious history recounted by his doting nurse Alison Cunningham, whom he called “Cummy”. As an adult he recalled “my sufferings when I was sick, [and] my delights in convalescence at my grandfather's manse of Colinton, near Edinburgh” as being among the most “powerful impressions of my childhood”.1 Years later, Stevenson dedicated his renowned collection of children’s poetry, A Child’s Garden of Verses (CGV ), to Cummy, with a retrospective acknowledgement of: Figure 1 Photograph of Robert Louis Stevenson by Henry Walter Barnett (Ca. 1893). State library of New South Wales, Australia. > the long nights you lay awake > > And watched for my unworthy sake: > > […] From the sick child, now well and old, > > Take, nurse, the little book you hold!2 Perhaps unsurprisingly, the poems in CGV contain both overt and subtle references to childhood illness, doubtless a literary testimony to the author’s own experience. In recent years, Stevenson’s work has experienced a resurgence in critical interest3 focused on a breadth of timely issues—from rich representations of Scottish cultural history4 to nuanced renegotiations of the dominant ethical codifications delineated by Victorian adventure narrative.5 Scholars note how his children’s poetry6 7 creatively explores that elusive “imaginative elsewhere” characteristic of the romance mode.8 (In one unpublished manuscript, Stevenson remarks: “a place …

Niemieccy okupanci w Warszawie a jawność Holokaustu

In several last years there have been many publications concerning the knowledge and attitudes of Germans in relation to the Holocaust. The author deals with the issue what the civilian population and the military troops stationed at that time in Warsaw knew about the Holocaust. The occupants quickly learned about the massacres of Jews. Precise information spread at a rapid pace, and consequently each of the occupants was well informed of the Holocaust. Very few Germans stationing in Warsaw condemned crimes committed against the Jews. There was consensus on the need of extermination of Jews, some reservations aroused only form in which the genocide was carrying on. Open violence intertwined with its general acceptance, which led to a progressive callousness.

Hydrogen Peroxide Residue on Tomato, Apple, Cantaloupe, and Romaine Lettuce after Treatments with Cold Plasma-Activated Hydrogen Peroxide Aerosols.

ABSTRACT Hydrogen peroxide (H2O2) has long been studied as an aqueous sanitizer to enhance microbial safety of fresh produce. Recently, we demonstrated that cold plasma-activated H2O2 aerosols, hereafter called ionized hydrogen peroxide (iHP), reduced populations of Salmonella, Listeria, and Escherichia coli by up to 5.5 log on surfaces of various produce items. However, the amount and fate of H2O2 residue left on fresh produce after treatments have not been evaluated. In the present study, H2O2 residue levels on apples, tomatoes, cantaloupe, and romaine lettuce were analyzed after treatments with 7.8% iHP at conditions that had been optimized and tailored for Salmonella reductions and each produce item. Results showed that higher residue levels were found on lettuce than on cantaloupe, tomatoes, and apples immediately after treatments. During storage at 10 and 22°C, H2O2 levels decreased rapidly and fell below 1 mg/kg within 1 day after treatments for all fresh produce items. Furthermore, the decrease was faster at 22°C than at 10°C. Most importantly, the levels of H2O2 residue on the fresh produce items were lower than those after wash with 1% H2O2 for 1 min. Overall, our results demonstrated that levels of H2O2 residue on fresh produce surfaces decomposed rapidly after treatment with iHP and did not appear to pose a safety concern after 1 day of storage.

JAMES ANDERSON, FISHERIES AND REGIONAL ECONOMIC DEVELOPMENT IN SCOTLAND

James Anderson was a contemporary of Adam Smith who is known primarily for having developed what subsequently came to be known as the Ricardian theory of rent. Anderson's primary concern however was the economic development of Scot land and he had a say in the policy measures undertaken in the 1780s. This article pres ents Andersons far sighted views on Infrastructure, Regional planning and the de velopment of new industries in a poor economy such as Scotland was in the 1780s.
The Magnetic Properties of GdxY6−xFe23 (x = 0,1,2,3) Compounds and Their Hydrides

The magnetic properties of the compounds GdxY6−xFe23 (x = 0,1,2,3) and their hydrides were studied. In the parent intermetallics, progressive substitution of Gd in place of Y in Y6Fe23 led to a reduction in the magnetic moment (~ 7 μB per Gd substituted) and an increase in the Curie temperature. For the hydrided materials a similar effect was observed (Gd substitution into Y6Fe23H16 resulted in a decrease in magnetic moment and an increase in Curie temperature). In all cases the hydride exhibited a larger moment and a higher Curie temperature than the corresponding intermetallic. This behavior indicates that in both the parent compounds and the hydrides the Fe sublattice is dominant and antiparallel to the Gd sublattice. Furthermore, the Fe moment is increased by hydrogenation, which seems to indicate that hydrogen creates vacancies in the minority spin d-band (i.e., hydrogen behaves as an electron acceptor). All hydrides retained the crystal structure of the parent materials (Th6Mn23 type), with a volume expansion of about 11%.
A coastal ocean numerical model

A coastal ocean model which, it is believed, is advanced beyond the current state of the art has been developed but is only in an early stage of application. Characteristics of the model include: a second moment turbulence closure model capable of accurate prediction of small scale turbulent mixing and derivative ocean features such as mixed layer temperature and depth. an algorithm which calculates the external (tidal) mode separately from the internal mode. The external mode, an essentially two-dimensional calculation, requires a short integrating time step whereas the costly, three-dimensional, internal mode can be executed with a long step. The result is a fully three-dimensional code which includes a free surface at no sacrifice in computer cost compared to rigid lid models. a “σ“ coordinate system with 20 levels in the vertical independent of depth. Thus, the environmentally important continental shelf, shelf bank and slope will be well resolved by the model. Furthermore, the model features increased resolution in the surface and bottom layers. coding deliberately designed for modern array processing computers. This is essential to three-dimensional ocean simulations requiring long integrations at tolerable cost.
Stentenna: a micromachined antenna stent for wireless monitoring of implantable microsensors

This paper reports on a micromachined stent that has been developed to serve as an antenna for wireless monitoring of implantable microsensors. A 4 mm long, 3.5 mm diameter design is fabricated from 50 /spl mu/m thick stainless steel foil using a batch-compatible micro electro-discharge machining process. As it is expanded during deployment, the stent transforms from a mesh that fits snugly around the angioplasty balloon into an inductive coil. This is accomplished by strategically located breakable links which change its electrical characteristics during the plastic deformation into its final shape. This 20 nH coil is coupled to a capacitive pressure microsensor that is approximately 1.2/spl times/4/spl times/0.5 mm/sup 3/ in dimensions. Wireless monitoring is demonstrated by showing that the resonant electrical loading provided by this LC tank to a separate transmitting coil shifts by 400 KHz over a pressure change of 800 Torr. The tests are performed in a liquid environment.
On the grooming of multicast traffic in WDM networks

In This work we consider the optimal dimensioning of optical networks for multicast traffic grooming problems on WDM networks under two practical scenarios. In both cases, for each multicast session the destination set consists of two disjoint subsets. In the first scenario only one subset of each multicast session must be accommodated while the other subset can only be accommodated if this results in no additional cost. In the second case, both subsets of each multicast session must be accommodated. However, each subset has different bandwidth requirements. We develop optimal and heuristic solutions for both the cases.
Genotypic and Phenotypic Comparisons of Chromosomal Types within an Indigenous Soil Population of Rhizobium leguminosarum bv. trifolii

The relative genetic similarities of 200 isolates of Rhizobium leguminosarum bv. trifolii recovered from an Oregon soil were determined at 13 enzyme loci by multilocus enzyme electrophoresis (MLEE). These isolates represented 13 antigenically distinct serotypes recovered from nodules formed on various clover species. The MLEE-derived levels of relatedness among isolates of R. leguminosarum bv. trifolii were found to be in good agreement with the levels of relatedness established by using repetitive (repetitive extragenic palindromic and enterobacterial repetitive intergeneric consensus) sequences and the PCR technique and with levels of relatedness from previously published DNA reassociation studies. BIOLOG substrate utilization patterns showed that isolates within an electrophoretic type (ET) were phenotypically more similar to each other than to isolates of other ETs. The soil isolates were represented by 53 ETs which could be clustered into seven groups (groups B, E, G, H1, H2, I, and J). Evidence for multilocus structure within the population was obtained, and group B was identified as the primary creator of the disequilibrium. Of 75 isolates belonging to the nodule-dominant serotype AS6 complex, 72 were found in group B. Isolates WS2-01 and WS2-02 representing nodule-dominant serotypes recovered from subclover grown at another Oregon site were also found in group B. Isolates representing the most numerous ETs in group B (ETs 2 and 3) were either suboptimally effective or completely ineffective at fixing nitrogen on six different clover species. Another four groups of isolates (groups A, C, D, and F) were identified when 32 strains of diverse origins were analyzed by MLEE and incorporated into the cluster analysis. Group A was most dissimilar in comparisons with other groups and contained strain USDA 2124 (T24), which produces trifolitoxin and has unique symbiotic characteristics.
Algebraic Surfaces and the Arithmetic of Braids, I

Conflict Management with Friends and Romantic Partners: The Role of Attachment and Negative Mood Regulation Expectancies.

The degree to which attachment orientations are related to negative mood regulation expectancies and conflict management strategies with best friends and romantic partners was examined for a sample of late adolescent, female college students (N = 140). Correlational and multiple regression analyses yielded results that were generally consistent with theoretical expectations. Adolescents with more insecure attachment orientations were likely to report having difficulties managing conflict with attachment figures and had less confidence regulating negative mood than individuals who endorsed more secure orientations. In addition, more avoidant and ambivalent attachment orientations often predicted specific conflict management difficulties, and confidence in negative mood regulation partially mediated these associations. The results are discussed in relation to previous research on attachment theory and implications for interventions are offered.
Tracking control of high-concentration photovoltaic systems for minimizing power losses

This paper presents three key factors that cause system mismatches and power losses in high-concentration photovoltaic (HCPV) systems. The first factor is the I–V mismatch within a module, similar to the manufacturing mismatches in conventional photovoltaic modules. The second factor is the misalignments amongst modules, and the third factor is the tracking control. Unlike in the conventional photovoltaic systems, the second and the third factors in HCPV systems introduce larger electro-optical mismatches due to narrow acceptance angles. We have developed a model to address these three factors. It allows an accurate estimation of power losses in HCPV systems, which enabled us to propose configurations to reduce power losses without adding additional electrical components to the system. Simulation results show that the power harvest can be increased as much as 8.5% for a system using open-loop controls by simply increasing the number of strings at the time of calibration. Experimental test results are presented for validation. Copyright © 2012 John Wiley & Sons, Ltd.
Information Sharing, Buyer-Supplier Relationships and Firm Performance: A Multi-Region Analysis

Purpose – The purpose of this paper is to examine the effects of information sharing capability on buyer‐supplier relationships and firm performance. It is proposed that information sharing capability, the integration of a firm's information/decision systems and business processes with those of supply chain partners, is an antecedent of collaborative buyer‐supplier relationships, defined in terms of supply chain and relationship architecture. Further, it is proposed that these relationships positively impact a firm's market and financial performance.Design/methodology/approach – This research uses multiple linear regression to analyze a set of survey data from the USA, Europe and New Zealand.Findings – Results demonstrate positive relationships between information sharing capability and buyer‐supplier relationships, and between relationships and performance.Research limitations/implications – Information sharing capability and buyer‐supplier relationships are complex, multi dimensional constructs. While t...
Magnetic susceptibility and heat capacity of Ce 2 Sn 5

Low-temperature (1.5--20 K) high-field (0--10 T) heat-capacity and magnetic-susceptibility (1.5--300 K) studies have been carried out on ${\mathrm{Ce}}_{2}$${\mathrm{Sn}}_{5}$. These studies reveal that ${\mathrm{Ce}}_{2}$${\mathrm{Sn}}_{5}$ orders magnetically at 3 K and exhibits Curie-Weiss behavior above 120 K with ${p}_{\mathrm{eff}=2.56{\ensuremath{\mu}}_{B}}$ indicating that Ce is trivalent in ${\mathrm{Ce}}_{2}$${\mathrm{Sn}}_{5}$. The peak in the heat capacity is suppressed in applied magnetic fields and disappears completely at high fields (g5.4 T) which suggests that the magnetic ordering is antiferromagnetic or ferrimagnetic. The magnetic entropy is about 42% of the theoretical expected entropy for a doublet ground state. The coefficient of the electronic heat capacity, which was derived from extrapolation of the heat-capacity data above the ordering temperature, is 22 mJ/mole-Ce? sup 2---. It is suggested that both magnetic Ruderman-Kittel-Kasuya-Yosida and Kondo exchange interactions coexist in this compound.
Coronary Risk Factors, II

Summary: Prospects for prevention of atherosclerosis in the young. There appears to be a need to protect our young from an atherogenic way of life. The average male child today has one chance in three of a cardiovascular catastrophe before age 60. Atherosclerosis and the conditions which predispose appear to have their onset in childhood. Correctable precursors of cardiovascular disease have been identified, and their contribution to risk has been estimated not only for adults but for college students as well. An analysis of the combined impact of atherogenic risk factors indicates that they exert greater force early in life than later. Although the optimal time to begin prophylaxis is not established, there is evidence to suggest that measures instituted late in life when lesions are advanced is of only limited value. Prevention of atherosclerosis is best viewed as a family affair since the propensity to disease and contributing factors tend to be shared by family members. It is also difficult to implement effectively preventive measures which include dietary changes, weight control, exercise and restriction of cigarettes for one family member without involving the rest of the family. Optimal levels of the correctable precursors of cardiovascular disease are not established for children. However, the rise in serum lipids, blood pressure, weight and blood sugar observed in transition from childhood to adult life is not inevitable, or desirable. Paediatricians can alter the appalling cardiovascular mortality statistics by not allowing the process or the habits and conditions which promote it to reach an irreversible stage. Cardiovascular disease may well begin in childhood with “medical trivia” such as a tendency to obesity, moderate cholesterol and blood pressure elevations, lack of exercise and the cigarette habit. In some respects a heart attack at age 45 can be regarded as a failure of the paediatrician. Awaiting proof of the efficacy of the indicated prophylactic measures is not acceptable since this will be a long time in coming. We must learn how to correct risk factors effectively in childhood as soon as they appear. We must establish goals based on optimal as distinct from usual levels of risk factors. Paediatricians' resolve about prevention of atherosclerosis in childhood needs to be strengthened and we must develop a sense of urgency about this.
Polydimensional Supersymmetric Principles

Systems of equations are invariant under "polydimensional transformations" which reshuffle the geometry such that what is a line or a plane is dependent upon the frame of reference. This leads us to propose an extension of Clifford calculus in which each geometric element (vector, bivector) has its own coordinate. A new classical action principle is proposed in which particles take paths which minimize the distance traveled plus area swept out by the spin. This leads to a solution of the 50 year old conundrum of `what is the correct Lagrangian' in which to derive the Papapetrou equations of motion for spinning particles in curved space (including torsion). Based on talk given at: 5th International Conference on Clifford Algebras and their Applications in Mathematical Physics, Ixtapa-Zihuatanejo, Mexico, June 27-July 4, 1999.
Inkjet printing of 3D nano-composites formed by photopolymerization of an acrylate monomer

Abstract This paper considers inkjet printing of optical quality 3D nano-composites from diethylene-glycol diacrylate monomer (DEGDA) containing ZrO2 nanoparticles at varying concentrations. One application for the composites is for gradient refractive index (GRIN) lenses. The process involves printing of a nanoparticle loaded monomer “ink” onto a substrate and then photopolymerizing the monomer layer by layer using UV light. The results of the study confirm that the presence of nanoparticles favorably affects the reaction kinetics. The reaction rate and chemical conversion are enhanced considerably by the nanoparticles. A seamless interface between the layers, which are 20 μm thick, may be achieved if the conversion level of the layer onto which ink is deposited is limited at 60 to 80%. Dynamic mechanical analysis (DMA) data indicate that both the glass transition and sub Tg viscoelastic properties are influenced by the nanoparticles. When nanoparticles are introduced the Tg relaxation shifts to lower temperatures and a sub Tg relaxation appears whose intensity increases with particle concentration. These results are consistent with a molecular confinement model involving a lower crosslink density rubbery layer at the polymer–particle interfaces.
Presentation of the C. Anderson Aldrich Award to Anna Freud

It is my privilege and pleasure to introduce Anna Freud to you and to read her paper for this most important occasion. Dr. Freud deeply regrets that she is unable to be with you and asked that I represent her at this meeting. May I say how appropriate and fitting it is to honor children throughout the world by conferring the C. Anderson Aldrich Award for 1974 on Dr. Anna Freud. Historically it is impressive that in 1968 and in 1971 this distinguished award was conferred on two of Anna Freud9s former students and colleagues. I refer to Dr. Edith B. Jackson and Professor Erik Erikson. Anna Freud, who started her professional activities as a teacher of young children, became the founder of child psychoanalysis. Throughout her career she has always had an affinity for working together with pediatricians, teachers, nurses, and all who are concerned with children. To this day she meets at least once a month with a group of distinguished English pediatric colleagues who have been her collaborators for more than 20 years. They share much in their curiosity about and compassion for children. They are devoted to helping children overcome illness and the handicaps of life. These include the burdens, threats, and losses associated with poverty, war, physical illness, genetic handicaps, and the destruction of the child9s body and mind that result from adult abuse and deprivation. In introducing Anna Freud, it is appropriate to call attention to her clinic, the Hampstead Child Therapy Center, and to her gallant colleagues with whom she works so closely on a daily basis.
A new explicit and unconditionally stable time-domain finite-element method

A new method for making an explicit time-domain finite-element method (TDFEM) unconditionally stable is developed for general electromagnetic analysis. In this method, for a given time step, no matter how large it is, we upfront adapt the TDFEM numerical system to exclude the source of instability. As a result, an explicit TDFEM simulation is made stable for an arbitrarily large time step irrespective of the space step. Numerical simulations have demonstrated the accuracy, efficiency, and unconditional stability of the proposed new method.
Turbulent free convection flow

Abstract The results of an experimental investigation of a turbulent free convection boundary layer are presented for a fluid with a low Prandtl number (mercury). The boundary layer was formed along the isothermally heated vertical wall of a cell. The measured mean temperature profiles and turbulent temperature distributions, indicated the existence of a fully developed boundary layer. In the recorded temperature spectra the high frequencies region, associated with dissipation, was found to exhibit an ƒ −3 dependence (ƒ is the frequency of the temperature fluctuations). The presence and development of a “convection subrange” was also identified, dependent upon the Rayleigh number and the location of the point of measurement with respect to the wall.
Porous ceramic scaffolds with complex architectures

This work compares two novel techniques for the fabrication of ceramic scaffolds for bone tissue engineering with complex porosity: robocasting and freeze casting. Both techniques are based on the preparation of concentrated ceramic suspensions with suitable properties for the process. In robocasting, the computer-guided deposition of the suspensions is used to build porous materials with designed three dimensional geometries and microstructures. Freeze casting uses ice crystals as a template to form porous lamellar ceramic materials. Preliminary results on the compressive strengths of the materials are also reported.
Spin-resolved photoelectron spectroscopy of Fe3O4

Abstract Spin-polarized photoelectron spectroscopy has been used to study the candidate half metal Fe 3 O 4 . By using higher photon energies we can study polarization in “as received” samples, essentially “looking through” the disrupted surface. Our data agree with theoretical calculations for Fe 3 O 4 but exhibit a lowered polarization.
Phainomena in Aristotle's methodology

This chapter explores how phainomena function in Aristotle's theoretical and practical sciences. Against Terence Irwin's attempt to distinguish sharply between empirical and dialectical inquiries, the author argues that for Aristotle different kinds of science share a common procedure in which phainomena perform two major functions. They serve as the starting-point of every search for first principles, especially when the science in question is demonstrative, since Aristotle insists that these principles themselves cannot be demonstrated. The chapter shows that how Aristotle justifies first principles in a way that parallels the so-called method of 'saving the phenomena'. It involves gathering the phainomena in a comprehensive way such that all or most of the logical possibilities are covered, and such that they conflict with each other. Such reliance on phainomena is typical of Aristotle's philosophical thinking, as distinct from Parmenides and Plato who insist on a sharp contrast between appearance and reality. Keywords:Aristotle; Parmenides; Phainomena ; Plato; Terence Irwin
Nano-YAG:Ce Mechanisms of Growth and Epoxy-Encapsulation

We have investigated the mechanism of nano-YAG:Ce growth in butanediol and glycol solvents. The static autoclave and low synthesis temperature (225 °C) that we employed provided conditions of slow growth in which we were able to observe an intermediate phase, a butanediol-intercalated layered alumina. This phase serves to passivate the surface in nano-YAG:Ce precipitates and thus contributes to increasing the quantum yield of YAG:Ce by diminishing surface effects such as Ce oxidation. While neat 1,4-butanediol results in precipitation of the nano-YAG:Ce, a mixture of 1,4-butanediol and diethylene glycol stabilizes a transparent colloid. We attribute this to higher solubility of the layered alumina intermediate in the solvent mixture and, thus, more homogeneous nucleation of the nano-YAG:Ce compared to heterogeneous nucleation in the neat 1,4-butanediol. However, the trade-off is slightly lower quantum yield in the transparent colloid, since the nano-YAG:Ce is not as thoroughly surface-passivated. With the...
Lysis of T4-infected bacteria in the absence of lysozyme

Abstract A mutant of phage T4 has been found which permits lysis of infected bacteria in the absence of lysozyme. The new mutation may affect a phage-directed synthesis of bacterial cell wall components; hence the name spackle (s).
Aligning images with CAD models via quaternion optimization

This paper introduces an algorithm for "mapping" locations in a 2D image of an object onto a 3D CAD model of that object. The goal is to align the image with the CAD model so that the location of various points in the image can be found on the object. We will actually present two methods for achieving this goal. One relies on projective invariants and requires no information about the camera parameters. Unfortunately, its performance is sometimes erratic in the face of particular types of errors. The other method assumes that the user is able to identify a minimum of 4 feature points in the image and the corresponding points on the CAD model. Beyond that, no information is assumed except for knowledge of the size of the camera's CCD and the location of the center of projection in the image. This second algorithm is highly accurate and robust in the face of real-world errors. We call this second algorithm the quaternion optimization algorithm. It positions the camera in CAD space so as to optimally align the matched features. This in turn permits the mapping of other image pixels to the CAD model.plica
Biosynthesis of Neurophysin Proteins in the Dog and Their Isolation1

Neurophysin (Np) is generally found in close association with vasopressin and oxytocin in the hypothalamo-neurohypophyseal complex. Dog neurophysin I and II have been isolated from fresh and frozen posterior pituitaries. The proteins were characterized on the basis of disc electrophoresis, immunological properties, amino acid composition and partial sequence determination. The amino terminal sequence of dog Np I is Ala-Ala-Leu- Asp - Leu - Asp - Val - Arg - Gin - Cys - Leu - Pro - Cys Gly-Pro-Gly-Gly-Gln-Gly- while that of dog Np- II is Ala-Met-Ser-Asp-Leu-Glu-Leu-. The dog Np I appears to be metabolically less stable than Np II. Isotope experiments with [35S]cystine or 3H-labeled amino acids using a design of “in vivo pulse and in vitro chase” as well as“ in vivo pulse and in vivo chase,” added further confirmation of the capability of the hypothalamic neurosecretory cells to synthesize concomitantly precursors of Np and vasopressin. The radioactively labeled precursors were converted to Np-like protein ...
SOME CORRELATES OF ADJUSTMENT BY PARAPLEGICS

This study investigated some correlates of adjustment to paraplegia, a physically immobilizing disability, which involves a number of frustrating, lifetime handicaps—such as the loss of the ability to walk, to feel sensation, to procreate, and the control of bowel and bladder function. From the results, it appears that the patient who was better able to adjust to a physically immobilizing handicap, was one who was better able to function in society prior to his disability, as indicated by his relatively higher educational and occupational attainments. Such a patient also was motivated by more theoretic-type interests than was the patient who adjusted less well to his disability.
A Technique for Estimating Marginal Posterior Densities in Hierarchical Models Using Mixtures of Conditional Densities

Abstract A technique called quantile integration is proposed for the estimation of marginal posterior densities arising in Bayesian models having hierarchical representations. The method is based on approximating marginal densities as mixtures of conditional densities, where the conditioning variables are selected deterministically from the mixing distributions. The form of the approximation makes it easy to implement, and the resulting approximations are computationally efficient to obtain. The technique leads to particularly simple approximations for the predictive and posterior densities in Kalman filter or state-space models, and specific formulas are provided for the special case in which innovations belong to location-scale families. Other applications include a hierarchical empirical Bayes model for Poisson rates and a hierarchical linear model with exchangeable regression parameters and unknown variance components.
Quantitative Multispectral Imaging System

We describe an imaging system that we developed to obtain quantitative multispectral visible images of objects from an airborne platform. The system consists of a Multispectral Image Intensified Camera coupled to a real-time image processing system. The image processing system monitors the camera performance in flight. In this article, we describe the image processing system, the multispectral camera, the calibration procedure and present stellar intensity and spectral measurements.
Carbonate deposition in an ephemeral siliciclastic alluvial system: Jurassic Shuttle Meadow Formation, Newark Supergroup, Hartford Basin, USA

Abstract Nonmarine carbonate accumulation, from a sedimentologic perspective, has multiple possible origins: clastic load, springs, groundwater discharge, soil development, biochemical seasonal changes, cave speleothems, and eolian influx. Many of these carbonates contain diagnostic textures from which origin is easy to ascertain. However, differentiating between clastic and spring/groundwater carbonates, especially in depositional systems dominated by siliciclastics, is not always simple; here criteria for recognition are developed. Subsurface hydrology and tectonic origin of the depositional basin, source rocks surrounding the basin, sedimentologic packaging and extent of the carbonates in question, as well as their sedimentary structures and fossil content, and stable isotopic analyses of the carbonates can all aid in determining carbonate origin and correctly assessing sedimentary and basin evolution. The present study focuses on a nonmarine carbonate deposit found within the Jurassic Shuttle Meadow Formation of the Hartford Basin, one of many rift basins which formed as a result of the opening of the North Atlantic Ocean during the Late Triassic to Early Jurassic. The upper 50 m of the formation at Plainville, Connecticut, is interpreted as continental in origin and is composed of five facies: red ripple cross-laminated muddy siltstones to sandstones (Fr, Sr), massive red siliciclastic mudstones (Fm), buff fine- to medium-grained horizontally laminated sandstones (Sh), red to white disrupted calcareous shales (Fl3), and rare micritic carbonates (Pm). Facies Fr, Sr, Sh, and Fm are interpreted as an alluvial plain system in an ephemeral setting with bedload sheetflooding as the dominant depositional mechanism, similar to the Channel Country drainage system of central Australia. In addition, preservation of lateral accretion sandstone sheets (accretionary benches) indicate that the Shuttle Meadow alluvial system was rapidly accreting. The anomalous existence of carbonate beds (in Facies Fl3 and Pm) in the SMF bedload-dominated siliciclastic sequence is attributed mainly to the unique nature of the clastic sediment load in the basin; no direct evidence for a spring/groundwater input is apparent. The shallow carbonate lake margin or a pond with vegetation and periodic exposure is envisioned as the depositional environment. The intraclastic texture of the micrites with rare primary relict lamination indicates early diagenetic alteration from root penetration, desiccation cracks, and burrowing.
Lens epithelial cells derived from αB-crystallin knockout mice demonstrate hyperproliferation and genomic instability

αB-crystallin is a member of the small heat shock protein family and can act as a molecular chaperone preventing the in vitro aggregation of other proteins denatured by heat or other stress conditions. Expression of αB-crystallin increases in cells exposed to stress and enhanced in tumors of neuroectodermal origin and in many neurodegenerative diseases. In the present study, we examined the properties of lens epithelial cells derived from mice in which the αB-crystallin gene had been knocked out. Primary rodent cells immortalize spontaneously in tissue culture with a frequency of 10−5 to 10−6. Primary lens epithelial cells derived from αB-crystallin−/− mice produced hyperproliferative clones at a frequency of 7.6 × 10−2, four orders of magnitude greater than predicted by spontaneous immortalization (1)⤻. Hyperproliferative αB-crystallin−/− cells were shown to be truly immortal since they have been passaged for more than 100 population doublings without any diminution in growth potential. In striking contr...
The structure and mechanics of Moso bamboo material

Although bamboo has been used structurally for millennia, there is currently increasing interest in the development of renewable and sustainable structural bamboo products (SBPs). These SBPs are analogous to wood products such as plywood, oriented strand board and glue-laminated wood. In this study, the properties of natural Moso bamboo (Phyllostachys pubescens) are investigated to further enable the processing and design of SBPs. The radial and longitudinal density gradients in bamboo give rise to variations in the mechanical properties. Here, we measure the flexural properties of Moso bamboo in the axial direction, along with the compressive strengths in the axial and transverse directions. Based on the microstructural variations (observed with scanning electron microscopy) and extrapolated solid cell wall properties of bamboo, we develop models, which describe the experimental results well. Compared to common North American construction woods loaded along the axial direction, Moso bamboo is approximately as stiff and substantially stronger, in both flexure and compression but denser. This work contributes to critical knowledge surrounding the microstructure and mechanical properties of bamboo, which are vital to the engineering and design of sustainable SBPs.
Progesterone receptor in granulosa cell tumor

Abstract A virilizing granulosa cell tumor of the ovary contained large amounts of testosterone and progesterone and small amounts of estrogens. Assays for progesterone receptor were positive, but estrogen receptor could not be detected. The presence of progesterone receptor in the tumor is consistent with recent evidence for a role of the receptor in the physiology of the Graafian follicle, and suggests the possibility that progestational therapy may be effective in advanced stage granulosa cell tumor.
β-Adrenoceptor Profile of Ractopamine HCl in Isolated Smooth and Cardiac Muscle Tissues of Rat and Guinea-pig

The investigational sympathomimetic amine, ractopamine hydrochloride, has been profiled for adrenergic activity in selected smooth and cardiac muscle preparations. There was no significant interaction of ractopamine with alpha-adrenergic receptors in the rat vas deferens at concentrations up to 10(-5) M. However, ractopamine produced a concentration-dependent increase in the force and rate of contractions of atria isolated from normal and reserpinized guinea-pigs (EC50 = 1 x 10(-7) M). These increases were submaximal compared with isoprenaline (70-85%), suggesting partial agonist activity at the beta 1-receptor site. Ractopamine completely relaxed the KCl-contracted guinea-pig trachea and rat costo-uterine smooth muscle to their resting tensions (EC50 = 3 x 10(-7) and 5.5 x 10(-8) M, respectively), indicative of full beta 2-agonist properties. Propranolol blocked the response of ractopamine in isolated tracheal and atrial tissues (pA2 = 7.70), demonstrating a beta-adrenergic mechanism of activity. Ractopamine also exhibited antagonism of the response of the guinea-pig trachea to the beta-agonist, isoprenaline. Relative to other beta-agonists, ractopamine was 100-fold more potent than the phenethanolamines, salbutamol and ritodrine, at the beta 1-adrenoceptor, and approximately 7- to 11-fold more potent than ritodrine, but only one-sixth to one-tenth as potent as salbutamol at the beta 2-adrenoceptor. Thus, ractopamine possesses significant beta 1- and beta 2-agonist properties. The submaximal stimulation of the force and rate of atrial contractions is indicative of a partial beta 1-agonist, while the maximal relaxation of the tracheal and costo-uterine smooth muscle is characteristic of a full beta 2-agonist.
Hermeneutics and inter-cultural dialog: linking theory and practice

Inter-cultural dialog is frequently treated as either unnecessary or else impossible. It is said to be unnecessary, because we all are the same or share the same ‘human nature'; it is claimed to be impossible because cultures seen as language games or forms or life are so different as to be radically incommensurable. The paper steers a course between absolute universalism and particularism by following the path of dialog and interrogation - where dialog does not mean empty chatter but the exploration of the ‘otherness’ of interlocutors on the far side of either assimilation or exclusion. Such dialog is the heart of hermeneutics as formulated by Hans-Georg Gadamer. The paper explores the question whether hermeneutical interpretation can be transferred from textual readings to the domain of cross-cultural encounters. After discussing both the historical development and the basic meaning of contemporary hermeneutics, the paper draws attention to the intimate linkage between interpretive understanding and ‘application’, or ‘practical philosophy.’ Drawing on the insights of Gadamer and some more overtly political thinkers, the paper then shows the relevance of hermeneutics for cross-cultural studies, as an antidote to the looming ‘clash of civilizations.’ It turns to some writings by Maurice Merleau-Ponty in order to emphasize the necessary linkage between interactive dialog and concrete embodied engagement. Undercutting purely mentalist or ‘idealist’ misconstruals of dialog, this linkage shows the mutual compatibility between Gadamerian hermeneutics and existential phenomenology.

Pulmonary Rehabilitation Improves Functional Status in Oncology Patients

Abstract Morris GS, Gallagher GH, Baxter MF, Brueilly KE, Scheetz JS, Ahmed MM, Shannon VR. Pulmonary rehabilitation improves functional status in oncology patients. Objective To determine if participation in a pulmonary rehabilitation (PR) program improved the functional and physiologic status of oncology patients with chronic symptoms of shortness of breath, fatigue, and/or exercise intolerance. Design Retrospective chart review. Setting Comprehensive cancer center. Patients Oncology patients (N=30) (either a solid or a hematologic malignancy) with chronic dyspnea, exercise intolerance, and/or decreased functional status who had participated in an outpatient PR program. Interventions The PR program used an individualized, progressive aerobic exercise program (2–3 sessions/wk for 8–12 weeks) that consisted of treadmill walking, riding on a bicycle ergometer and exercising on a sliding board. This program also included a didactic educational and psychosocial component. Main Outcome Measures Functional status and exercise tolerance was assessed by the 6-minute walk test (6MWT) conducted at the beginning and end of the program. Self reports of perceived exertion and dyspnea were collected during and after these tests. Physiologic status was assessed by calculating 6-minute walk work (body mass × 6-minute walk distance). Results Participation in the outpatient PR program significantly increased the 6-minute walk distance (21%, P P Conclusions The current study, although limited in size, suggests that participation in a comprehensive outpatient PR program is safe and of benefit in a heterogeneous population of oncology patients with pulmonary symptoms.
Deformation twinning and twinning related fracture in coarse-grained α-uranium

Abstract An investigation of deformation twinning in coarse-grained α-uranium was conducted within the heat-affected zone of weld specimens tested in tension. Twins and twin interactions were studied both at fracture surfaces and sub-surface, using transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD). The fracture surface plane was identified using TEM of foils cut from the fracture surface using a focused ion beam. Intersecting twins found in these foils were also analyzed. EBSD was also used to analyze twins and twin interactions at and below the fracture surface. Fracture parallel to {1 7 2} twin planes and {1 7 2} twin crossings were observed, in agreement with previous optical/Laue diffraction studies. Previously unobserved crossings of {1 7 2} twins by {1 1 2} twins were also frequently observed. These twin interactions are interpreted in terms of previously established crystallographic criteria for twin crossings.
