209. Promotion of breastfeeding -- beyond the benefits.

Author

Westdahl C and Page-Goertz S

Abstract

Breastfeeding provides many health, social, and emotional benefits to both mother and infant. Increasing the initiation rate of breastfeeding to 75% and eliminating disparities among ethnic groups is an important public health goal. Childbirth educators can improve their effectiveness as promoters of breastfeeding by adopting social marketing communication strategies. This article presents The Best Start Three-Step Counseling Strategy adapted for use in group discussions. The use of this strategy offers unique opportunities to understand women's attitudes, needs, and the larger social issues that impact a woman's infant feeding decision and to improve effectiveness in promoting the decision to breastfeed.

Abstract

A high-quality double-polarization data set for the helicity dependence of the total and differential cross-sections for both γp → Nπ channels in the Δ region has been obtained in the framework of the GDH experiment. The experiment, performed at the Mainz microtron MAMI, used a 4π detection system, a circularly polarized photon beam, and a longitudinally polarized frozen-spin target. These data are included in the database to perform a multipole analysis to determine the properties of the Δ(1232)-resonance. For the resonant Δ(1232) multipoles we find a very good agreement with previous analyses, while the nonresonant ones show significant deviations. [ABSTRACT FROM AUTHOR]

Abstract

We present a determination of the gluon polarization Delta G/G in the nucleon, based on the helicity asymmetry of quasi-real photoproduction events, Q^2 = 0.002 +- 0.019(stat.) +- 0.003(syst.). From this value, we obtain in a leading-order QCD analysis Delta G/G=0.024 +- 0.089(stat.) +- 0.057(syst.) at x_g = 0.095 and mu^2 =~ 3 (GeV}/c)^2.

Abstract

We present the final results of the spin asymmetries A(1) and the spin structure functions g(1) of the proton and the deuteron in the kinematic range 0.0008 < x < 0.7 and 0.2 < Q(2) < 100 GeV2. For the determination of A(1), in addition to the usual method which employs inclusive scattering events and includes a large radiative background at low x, we use a new method which minimizes the radiative background by selecting events with at least one hadron as well as a muon in the final state. We find that this hadron method gives smaller errors for x < 0.02, so it is combined with the usual method to provide the optimal set of results. [S0556-2821(98)07017-9].

Abstract

The polarized solid state target is an indispensable experimental tool to study single and double polarization observables at low intensity particle beams like tagged photons. It was one of the major components of the Crystal-Barrel experiment at ELSA. Besides the operation of the ’CB frozen spin target’ within the experimental program of the Crystal-Barrel collaboration both collaborative groups of the D1 project, the polarized target group of the Ruhr Universität Bochum and the Bonn polarized target group, have made significant developments in the field of polarized targets within the CRC16. The Bonn polarized target group has focused its work on the development of technically challenging polarized solid target systems towards the so called ’4π continuous mode polarized target’ to operate them in combination with 4π-particle detection systems. In parallel, the Bochum group has developed various highly polarized deuterated target materials and high precision NMR-systems, in the meantime used for polarization experiments at CERN, JLAB and MAMI, too.

Abstract

Our group is constructing a polarized deuteron target system for a measurement of &Drarr;(↘p)T reaction at low energies. If we assume that the incident energy of deuteron beam is 20 MeV, and its intensity is 1 nA, required specifications to the target system are the polarization is larger than 40%, the target thickness is ∼ 1 mg/cm², a cooling power of refrigerator is several mW at 200 mK. At present, the lowest temperature of 200 mK and the cooling power of 2.6 mW at 500 mK was achieved. On the other hand, the development, of target material has been made. The polarization of 17% was obtained to a electron irradiated — CD[sub 2] foil, with a doze of 1 x 10[sup 16] e[sup -]/cm². [ABSTRACT FROM AUTHOR]

γ p → K + Λ differential cross sections and recoil polarisation data from threshold for extremely forward angles are presented. The measurements were performed at the BGOOD experiment at ELSA, utilising the high angular and momentum resolution forward spectrometer for charged particle identification. The high statistics and forward angle acceptance enables the extraction of the cross section as the minimum momentum transfer to the recoiling hyperon is approached. [ABSTRACT FROM AUTHOR]

The BGOOD experiment at the ELSA facility in Bonn has been commissioned within the framework of an international collaboration. The experiment pursues a systematic investigation of non-strange and strange meson photoproduction, in particular t-channel processes at low momentum transfer. The setup uniquely combines a central almost 4 π acceptance BGO crystal calorimeter with a large aperture forward magnetic spectrometer providing excellent detection of both neutral and charged particles, complementary to other setups such as Crystal Barrel, Crystal Ball, LEPS and CLAS.

Abstract

Breeding oilseed rape for oil and protein contents may have led to differences in seedling emergence in genotypes. New opportunities for deep automated phenotyping of germination and seedling growth are being developed on phenotyping platforms. Our aim was to demonstrate that using these data to parameterize a crop emergence model complements field experiments for the evaluation of differences among genotypes. Five genotypes, chosen in a diverse set of winter oilseed rape for their different germination speeds, were phenotyped for germination at different temperatures and water potentials as well as for radicle and hypocotyl growth. These data were used as parameters to run the SIMPLE crop emergence model over a period of 27 years (1985–2012), at two locations, one in France and one in Germany, and at four sowing dates. Field experiments were performed in 2012, 2013 and 2014, and the emergence of the five genotypes was measured at early and late sowing dates. First, model predictions were compared with observed field emergence in the French sowing trials in 2014. The model proved to be rather good at predicting the emergence of the genotypes. Then, for the simulation study, the model extended the observed differences between locations and sowing dates over a greater number of years. The model also identified the main reasons for non-emerging seedlings and their frequencies in the simulated sowings. Differences between the five genotypes were on average very small, but complex interactions appeared that led to bigger differences under certain sowing conditions. This study demonstrates that combining deep phenotyping with crop models in simulation studies paves the way for more precise and detailed evaluation of genotypes. [ABSTRACT FROM AUTHOR]

Abstract

The helicity dependence of the total cross-section and the invariant-mass distributions in the ( pπ±) and (π+π-) final states for the γ p → pπ+π- reaction have been measured for the first time at incident photon energies from 400 to 800MeV. The measurement was performed with the large-acceptance detector DAPHNE at the tagged photon beam facility of the MAMI accelerator in Mainz. Although this channel is found to be predominantly excited by the intermediate production of a Δπ state, both the measured unpolarized and the helicity-dependent observables are generally not well described by the existing theoretical models.

Abstract

The G asymmetry of the γ p↦ Nπ reaction has been measured for the first time for E γ = 340±14 MeV. This observable, for which very scarce published data exist, plays an important role to disentangle the contributions of the various nucleon resonances. The experiment, performed at the Mainz microtron MAMI, used a 4π-detector system, a linearly polarized, tagged photon beam, and a longitudinally polarized proton target. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: The helicity dependence of the total cross section for the reaction has been measured for the first time at incident photon energies from 400 to 800 MeV. The measurement, performed at the tagged photon beam facility of the MAMI accelerator in Mainz, used the large acceptance detector DAPHNE and a longitudinally polarized frozen-spin target. This channel is found to be excited predominantly when the photon and proton have a parallel spin orientation, most likely due to the intermediate production of the resonance. However, the contribution of the antiparallel spin configuration, arising from other reaction mechanisms, is also not negligible. This result gives important new information to resolve the existing model discrepancies in the identification of the nucleon resonances contributing to this channel. [Copyright &y& Elsevier]

Abstract

The reaction pp→ΛΛ was examined by LEAR experiment PS185/3 at 1.525 and 1.640 GeV/c. The proton target was transversely polarized in order to measure the depolarization and spin transfer. Theoretical calculations of Dnn, the component of the depolarization normal to the production plane, differ greatly according to whether quark-gluon or meson-exchange models are employed. The measured Dnn and spin transfer Knn appear to be inconsistent with the specific models cited. [Copyright &y& Elsevier]

Abstract

This study determined the frequency and the clinicopathologic and genetic features of colorectal carcinomas driven by oncogenic fusions of the anaplastic lymphoma kinase gene (ALK). Of the 8150 screened tumors, 12 (0.15%) were immunohistochemically ALK-positive with D5F3 antibody. These cancers harbored CAD-ALK (n=1), DIAPH2-ALK (n=2), EML4-ALK (n=2), LOC101929227-ALK (n=1), SLMAP-ALK (n=1), SPTBN1-ALK (n=4), and STRN-ALK (n=1) fusions, as detected by an RNA-based next-generation sequencing assay. ALK fusion carcinomas were diagnosed mostly in older patients with a 9:3 female predominance (median age: 72 y). All tumors, except a rectal one, occurred in the right colon. Most tumors were stage T3 (n=7) or T4 (n=3). Local lymph node and distant metastases were seen at presentation in 9 and 2 patients. These tumors showed moderate (n=6) or poor (n=3) glandular differentiation, solid medullary growth pattern (n=2), and pure mucinous morphology (n=1). DNA mismatch repair-deficient phenotype was identified in 10 cases. Tumor-infiltrating lymphocytes were prominent in 9 carcinomas. In 4 carcinomas, tumor cells showed strong, focal (n=3), or diffuse programmed death-ligand 1 immunoreactivity. CDX2 expression and loss of CK20 and MUC2 expression were frequent. CK7 was expressed in 5 tumors. Four patients died of disease within 3 years, and 7 were alive with follow-up ranging from 1 to 8 years. No mutations in BRAF, RAS, and in genes encoding components of PI3K-AKT/MTOR pathway were identified. However, 1 tumor had a loss-of-function PTEN mutation. Aberration of p53 signaling, TP53 mutations, and/or nuclear accumulation of p53 protein was seen in 9 cases. ALK fusion colorectal carcinomas are a distinct and rare subtype of colorectal cancers displaying some features of mismatch repair-deficient tumors.

Abstract

This article presents information on the first measurement of the helicity-dependent differential cross section. Over many years, experimental and theoretical studies of nucleon resonances have been performed using meson reactions, mainly pion-induced reactions and pion photoproduction processes. Recently, a number of experimental and theoretical advances in the study of ? photoproduction have taken place. The experiment was carried out at the Glasgow-Mainz tagged-photon facility of the MAMI accelerator in Mainz. Circularly polarized photons were produced by bremsstrahlungof longitudinally polarized electrons. A strained GaAs photocathode routinely delivered electrons with a degree of polarization of about 75% [17]. The electron polarization was monitored with a precision of 3% by means of a Moller polarimeter.

Abstract

Recent developments in MMC – HVDC schemes have resulted in increased power ratings and dc-side voltage levels which surpass 500 kV. Additionally, besides offshore applications, cable transmission is increasinglypromoted also for onshore applications. To tackle challenges related to those developments, the rigid bipolar HVDC configuration is considered an attractive solution. First projects of this system type in the voltage range of 500 kV are already under construction. This paper evaluates characteristic overvoltage transients in the rigid bipolar configuration. Selected EMT–simulationresults highlight the different performance related to transient voltage stresses occurring in symmetrical monopolar schemes. Related findings help stakeholders to develop an understanding of the rigid bipolar configuration, and therefore contributes to ongoing discussions within the community.

Abstract

The γ p → K + Σ 0 differential cross section at extremely forward angles was measured at the BGOOD experiment. A three-quarter drop in strength over a narrow range in energy and a strong dependence on the polar angle of the K + in the centre-of-mass of the reaction is observed at a centre-of-mass energy of 1900 MeV. Residing close to multiple open and hidden strangeness thresholds, the structure appears consistent with meson-baryon threshold effects which may contribute to the reaction mechanism.
