Abstract

D∗± production via e+e−→D∗±X has been measured at an average CM energy of 34.4 GeV. The D∗± energy spectrum is hard, with a maximum near χ = 0.6. The size of the D∗ cross section, R D ∗ = σ( e + e − → D ∗ X ) σ μμ = 2.50 ± 0.64 ± 0.88 (assuming R D ∗0 = R D ∗+ ) indicates that a large fraction of charm quark production yields D∗ mesons. The D∗± angular distribution exhibits a forward—backward asymmetry, A = −0.28 ± 0.13. This is consistent with that expected in the standard theory for weak neutral currents and leads to |gAc| = 0.89 ± 0.44 for the axial vector coupling of the charm quark.

Abstract

We present an analysis of electroweak leptonic couplings from high statistics experiments on Bhabha scattering and μ pair production at an energy of 34.5 GeV. The forward-backward charge asymmetry of the μ pairs was measured to be −0.098±0.023±0.005. The data were found to agree well with the standard theory of electroweak interaction giving sin2θW=0.27±0.07. The leptonic weak couplings were determined to begv=0.000±0.170 andgA=−0.481±0.055. The data were also used to investigate a class of composite models for leptons.

Abstract

We present an analysis of ρ0ρ0 production by two photons in the ρ0ρ0 invariant mass range from 1.2 to 2.0 GeV. From a study of the angular correlations in the process γγ→ρ0ρ0→π- π+π- we exclude a dominant contribution from JP=0- or 2- states. The data indicate sizeable contributions from JP=0+ for four pion masses M4π1.7 GeV. The data are also well described by a model with isotropic production and uncorrelated isotropic decay of the ρ0,s. The cross section stays high below the nominal ρ0ρ0 threshold, i.e. M4π

Abstract

Increasingly, people with mental health problems in Ireland and in the UK are receiving mental health services in the community. The aim of this study was to identify the predominant approaches to care used by community psychiatric nurses (CPNs) and the theoretical bases of their practice. One hundred and sixteen questionnaires out of 203 sent to CPNs throughout Ireland were returned, giving a response rate of 57.1%. In addition, 33 home visits by 13 CPNs were observed. The findings showed that over 96% of the sample were in full-time employment; most (71.4%) worked a 9-5 weekday shift; 31% had a postregistration counselling qualification, and about a quarter were based in hospitals. The average caseload size was 61 and the service was predominantly a closed referral one. The main client care activities were: assessment of clients, medication management, health promotion, and client and family support. From the observations, there was no evidence of CPNs practising cognitive, behaviour therapy or family therapies to any great extent. This study provides baseline data for monitoring trends in community mental health nursing in Ireland, and for informing future policy regarding service provision and training of CPNs.

Abstract

This article describes how one of the fundamental hardware stumbling blocks to fully achieving software-defined radio, high speed, and wide dynamic range data conversion can be overcome with the selective application of a class of asynchronous logic referred to as delay-insensitive logic. Certain characteristics of delay-insensitive logic can be exploited using unique architectures to reduce digital switching noise and whiten the noise signature. The result is enhanced mixed mode performance in highly integrated systems. The performance enhancement of an interpolating digital-to-analog converter is presented as a specific example. Because the concept of delay-insensitive logic is not familiar to most engineers, a brief introduction to the general concept is given.

Abstract

This paper presents a novel delay-insensitive three dimension pipeline array multiplier. The organization combines deep (gate-level) pipelining of Manchester adders with a two dimensional cross-pipeline mesh for multiplicand and multiplier propagation and partial product bits calculation. Fine grain pipelining with elimination of broadcasting and completion trees leads to high-throughput without use of dynamic logic that leaves the door open for further improvement of performance.

Abstract

We have observed τ pair production at average CM energies of 13.9, 22.3, 34.5 and 43.1 GeV. The cross-sections are consistent with QED, the cut off parameters beingΛ +>161 GeV andΛ −169 GeV (95% CL). The topological branching fraction of the τ to 1 charged particle,B 1, is 0.847±0.011 (stat) −0.013 +0.016 (syst) and no decays to 5 charged particles were observed resulting inB 5

Abstract

Exclusive production of proton-antiproton pairs by two photon scattering at CM energies between 2.0 GeV and 3.1 GeV has been measured with the TASSO detector at the e + e − storage ring PETRA. The angular distribution is flat within the accepted CM angular range | cos Θ ∗ |⩽0.7 . The integrated cross section (| cos Θ ∗ |⩽0.6) drops from about 4 nb at 2 GeV to less than 0.5 nb above 3 GeV. For the two-photon production of the η c (2984) and its subsequent decay into proton-antiproton the upper limit Γ(η c →γγ)· B (η c → p p ) keV (95% CL) is found.

Abstract

D ∗± production via e + e − → D ∗± X was studied at CM energies near 34 GeV. The charged particles produced in the hemisphere opposite to that of the D ∗ were used to investigate the fragmentation of charm jets. All spectra studied show a close similarity between the charm jet and the average jet obtained by summing over all quark flavours. The spectra of particles produced in the D ∗ hemisphere were used to study separately first rank and higher rank fragmentation.

Abstract

Multihadron events produced bye+e− annihilation at a c.m. energy of 34.6 GeV have been used to determine αs. The predictions of 1 st and 2nd order QCD models with independent jet and string fragmentation have been compared to a large variety of kinematic variables such as event shapes, transverse momentum spectra, jet masses, 3-cluster thrust and the asymmetry of energy-energy correlations. The value of αs has been found to depend on the variables used, on the fragmentation model and on the treatment of soft gluons in the 2nd order QCD calculation. Within the models considered αs has been found in complete 2nd order QCD to lie between 0.12 and 0.23.

Abstract

We have observed exclusive production of K + K − and K S O K S O pairs and the excitation of the f′(1515) tensor meson in photon-photon collisions. Assuming the f′ to be production in a helicity 2 state, we determine Λ( f ′ → γγ) B( f ′ → K K ) = 0.11 ± 0.02 ± 0.04 keV . The non-strange quark of the f′ is found to be less than 3% (95% CL). For the θ(1640) we derive an upper limit for the product Λ(θ rarr; γγ K K ) keV (95% CL ) .

Abstract

Results onK0 and Λ production ine+e− annihilation at c.m. energies of 14, 22 and 34 GeV are presented. The shape of theK0 and Λ differential cross sections are very similar to each other and to those of π±,K± and\(p(\bar p)\). Scaling violations are observed forK0 production. We obtain a value for the probability to produce strange quark-antiquark pairs relative to that to produce up or down quark-antiquark pairs of 0.35±0.02±0.05. The value ofRh=σ(e+e-→hX)/σµµ is shown to rise steadily with c.m. energy for all particle species. At 34 GeV we find 1.48±0.05K0 and 0.31±0.03 Λ per event. We have searched for possible Λ polarization. The production ofK0's and Λ's in jets is examined as a function ofpT2 and rapidity and compared to that of all charged particles; the yields in two and three jets are also investigated. Results are presented from events with two baryons\((\Lambda ,\bar \Lambda ,por\bar p)\) observed.

Abstract

Studies with laboratory animals have shown that pertechnetate ion is selectively concentrated in the thyroid gland, salivary glands and stomach, and selectively excluded from the cerebrospinal fluid almost to the same extent as inorganic iodide. Since the radionuclide technetium-99m gives extremely low energy dissipation in tissue, human studies were undertaken to evaluate pertechnetate-99m as a clinical tracer material. After intravenous administration, approximately 30% of the technetium-99m is excreted in the urine over the first 24 hr. The pertechnetate remaining in the body is evidently slowly metabolized, since the urinary excretion decreases markedly while fecal excretion increases progressively to a total of about 20% of the injected dose at 72 hr. In normal subjects, up to 2 % of the radioactivity from intravenously injected pertechnetate-99m is accumulated by the ion-concentrating mechanism of the thyroid at 1 hr, which corresponds closely to the accumulation of radioiodide in the gland blocked ...

Abstract

The inclusive production of π± and K± mesons and of protons and antiprotons in e+e- annihilation has been measured at c.m. energies of W=14, 22 and 34GeV. Using time of flight measurements and Cerenkov counters the full momentum range has been covered. Differential cross sections and total particle yields are given. At particle momenta of 0.4 GeV/c more than 90% of the charged hadrons are pions. With increasing momentum the fraction of pions among the charged hadrons decreases. At W=34 GeV and a momentum of 5 GeV/c the particle fractions are approximately π±:K±:p, {Mathematical expression}. On average an event at W=34 GeV contains 10.3±0.4π±, 2.0±0.2 K± and 0.8±0.1 p, {Mathematical expression}. In addition, we present results on baryon correlations using a sample of events where two or more protons and/or antiprotons are observed in the final state. © 1983 Springer-Verlag.

Abstract

We have measured the cross sections for e+e− → e+e−, e+e− → μ+μ−, e+e− → γγ and e+e− → hadrons in an energy scan at center of mass energies between 39.79 and 46.72 GeV in 30 MeV steps. New spinless bosons, whose existence has been postulated as a possible means to explain the anomalously large radiative width of the Z0 found at the CERN SPS p p collider, are ruled out in the scan region. The data are used to set limits on the couplings to lepton, photon and quark pairs of bosons with masses above 46.72 GeV.

Abstract

Background: College students are among 48.1 table million Americans who experience food insecurity, affecting aspects of daily living, health, and academic performance. This study sought to assess food security in nursing students to determine the prevalence and significance of this issue., Methods: A mixed-methods descriptive design was utilized to collect and analyze data through an online survey of junior and senior undergraduate nursing students. Both qualitative and quantitative questions were related to personal experience with food insecurity., Results: Approximately 40% of students responded that they were Sometimes/Often worried that food would run out before the next income arrived. In addition, 52% of the participants Sometimes/Often could not afford an adequate amount of food, and 35% reported having a shortage of food., Conclusion: University leadership, College of Nursing administrators, and nursing faculty should be aware of food insecurity among their students and identify strategies to assess and decrease this issue., (© 2020 Wiley Periodicals LLC.)

Abstract

A recent multi-centre observational evaluation investigated the effect of a topical haemoglobin spray (Granulox, Infirst), used as an adjunct to standard care, on wound size reduction in 17 patients (4 females/13 males) with 20 chronic diabetic foot ulcers (DFUs) over a 4-week period. In 14 of the 18 wounds that completed the evaluation (one patient dropped out due to an infection) there was a mean reduction of 53.8% (range: 11.9-100%). The product was acceptable to both patients and clinicians, who all found it easy to use. This article describes the outcomes for the remaining 13 patients (with 15 wounds) who continued using the spray after the 4-week evaluation ended. (Data are not available for two patients and the one patient who healed during the 4-week evaluation.) By 12 weeks, three wounds (20%) had healed, eight (53%) were progressing towards healing, three (20%) increased in size and one (7%) was slow healing.

Abstract

Objective: To evaluate the performance and safety of Exufiber, a gelling fibre wound dressing incorporating Hydrolock technology, in the management of highly exuding diabetic foot ulcers (DFUs)., Method: The study was conducted over a 12 week period involving a total of 21 patients with DFUs. A number of parameters were measured to monitor the change in condition of the peri-wound skin from baseline assessments. The evaluation of dressing-related pain was measured using a 100mm visual analogue scale (VAS). Wound status (measured by changes in wound size and healing phase) was recorded. Clinician/patient opinions of the test product and technical performance (measured by the presence of dressing residue following removal and handling of wound exudate) were also recorded., Results: The number of patients with healthy/intact peri-wound skin increased from baseline to the final visit. There was also a steady decrease in wound exudate volume throughout the study. Pain levels were very low throughout the investigation period, bearing in mind issues with neuropathy. A gradual decline in all wound size parameters from baseline to the final visit was noted; there was a statistically significant reduction in both wound area (cm(2)), p=0.0094, and wound volume (cc), p=0.0056, from baseline to the final visit. Throughout the study, a small decline in the mean percentage of granulation tissue within the wound paralleled a gradual increase in the mean percentage of epithelialisation tissue, while the percentage of non-viable tissue remained very low. The primary endpoints of product performance and safety were measured by the changes from baseline in the condition of the peri-wound skin. Results showed that the number of patients with healthy/intact peri-wound skin increased from baseline to the final visit, increasing from 6 patients (28.6%) at baseline to 14 patients (66.7%) at the final visit. There were no occurrences of product degradation on the skin and no reported adverse events (AE)/adverse device effects (ADE) during the course of the study that were judged to be related to the investigational product., Conclusion: This study has demonstrated the capacity for the test dressing to minimise damage to the peri-wound skin and dressing-associated pain. Despite the majority of wounds remaining unhealed at the final visit, improvements were noted in terms of tissue type and a significant reduction in wound area and volume. The technical performance of the dressing was demonstrated by an ability to absorb and retain exudate. Product safety was also demonstrated by an increase in the number of patients with healthy/intact peri-wound skin and the lack of identified product-related AE/ADEs., Declaration of Interest: The study was supported by an unrestricted educational grant from Mölnlycke Health Care.

Abstract

Aim: The aim of this multi-centre observational evaluation was to assess the percentage reduction in wound area of non-healing diabetic foot ulcers (DFUs), treated with Granulox haemoglobin spray over a 4-week period. Secondary outcome parameters--for example, adverse events, patient acceptability and ease of use--were also recorded., Method: After a run-in-period (2 weeks for existing patients and 4 weeks for new patients) to determine if the wounds were non-healing despite receiving local best practice, patients whose foot ulcers had decreased in size by < 20% were then entered into the evaluation. A sample of 17 patients (4 females and 13 males), comprising 4 with type 1 and 13 with type 2 diabetes, with a total of 20 DFUs, met the inclusion criteria. These data were collected from six sites across the UK., Results: There was an overall positive reduction in size in 15 of the wounds, equating to a mean reduction of 53.8% (standard deviation (SD): 26.6; range: 11.9-100%). One participant, with two ulcers, had to be withdrawn due to infection. All clinicians and participants found the product easy to use., Conclusion: The addition of a topical oxygenation therapy in this cohort of non-healing DFUs showed reduction in wound surface area and progression to healing. The product was also found to be acceptable and very easy to use by both participants and clinicians.

Abstract

While every attempt can be made to avoid the development of diabetic foot ulcers, it is inevitable that some patients will present with them. Once they develop, these ulcers are hard to heal, placing the patient at increased at risk of infection and, ultimately, amputation. It is vital, therefore, that health-care professionals are able to recognise the signs of increased bioburden and infection, so that prompt treatment can be given.

Abstract

Lead (Pb) concentrations in whole blood and δ-aminolevulinic acid (ALA) concentrations in plasma and whole blood from 37 cattle with suspected Pb exposure were determined in order to investigate the usefulness of ALA as a biological indicator for Pb poisoning in cattle. Cows were divided into 4 groups based on blood Pb, as follows: <30 ppb (group 1), 30-100 ppb (group 2), 100-300 ppb (group 3), and >300 ppb (group 4). The derivatization reaction for ALA was improved by a greater than 2-fold measure in whole blood and by a 10-fold measure in plasma by adding 75 and 50 µl of 0.1 N HCl, respectively. Blood Pb concentrations ranged from <25 ppb to 1,006 ppb (185.5 ± 254.9 ppb), with 17 samples containing >50 ppb Pb. Delta-aminolevulinic acid concentrations in whole blood and plasma ranged from <62.7 ppb to 96.9 ppb (77.4 ± 8.4 ppb) and from <5.0 ppb to 24.0 ppb (4.6 ± 3.8 ppb), respectively. Whole blood ALA did not correlate with blood lead concentrations in any group. Increase in plasma ALA concentration was dependent on blood Pb concentration. There was no correlation between blood Pb concentration and plasma ALA concentration in group 2 (n  =  4), but correlation coefficients were 0.736 in group 3 and 0.807 in group 4, respectively. The correlation coefficient was increased to 0.851 when groups 3 and 4 were combined. Based on these observations, in cattle, plasma ALA is a more reliable biological biomarker for Pb exposure than is blood ALA.

Abstract

Increasingly, people with mental health problems in Ireland and in the UK are receiving mental health services in the community. The aim of this study was to identify the predominant approaches to care used by community psychiatric nurses (CPNs) and the theoretical bases of their practice. One hundred and sixteen questionnaires out of 203 sent to CPNs throughout Ireland were returned, giving a response rate of 57.1%. In addition, 33 home visits by 13 CPNs were observed. The findings showed that over 96% of the sample were in full-time employment; most (71.4%) worked a 9-5 weekday shift; 31% had a postregistration counselling qualification, and about a quarter were based in hospitals. The average caseload size was 61 and the service was predominantly a closed referral one. The main client care activities were: assessment of clients, medication management, health promotion, and client and family support. From the observations, there was no evidence of CPNs practising cognitive, behaviour therapy or family therapies to any great extent. This study provides baseline data for monitoring trends in community mental health nursing in Ireland, and for informing future policy regarding service provision and training of CPNs.
