ALEXITHYMIA DIFFERENCES AND THE THEORY OF MIND AMONG CHILDREN WITH NURSING CAREERS PARENTS
Different studies have presented various results on Alexithymia and Theory of Mind in both women and men. Accordingly, the purpose of this study is to determine differences of alexithymia and theory of mind among Children survivors in the Kurdistan's among children with nursing careers parents. Therefore, 284 nurses (123 boys and 161 girls) were chosen among children with nursing careers parents located in hospital sanandaj in 2016. Then the respondents completed the Toronto Alexithymia and Mind Reading through Eyes questionnaires. Descriptive Statistical Method and Multi-Variate Variance Analysis were used to analyze the data. Results of the research showed that the rates of theory of mind and externally orientated thinking were different in both genders. In other words, survival boys showed higher levels of externally orientated thinking and lower levels of theory of mind compared to survival girls
Proton-deuteron radiative capture cross sections at intermediate energies
Differential cross sections of the reaction have been
measured at deuteron laboratory energies of 110, 133 and 180 MeV. The data were
obtained with a coincidence setup measuring both the outgoing He and the
photon. The data are compared with modern calculations including all possible
meson-exchange currents and two- and three- nucleon forces in the potential.
The data clearly show a preference for one of the models, although the shape of
the angular distribution cannot be reproduced by any of the presented models.Comment: 6 pages, 6 figures, accepted for publication in EPJ
Search for Three-Nucleon Force Effects in Analyzing Powers for p→d Elastic Scattering
A series of measurements have been performed at KVI to obtain the vector analyzing power Ay of the 2H(p→,pd) reaction as a function of incident beam energy at energies of 120, 135, 150, and 170 MeV. For all these measurements, a range of ϑc.m. from 30° to 170° has been covered. The purpose of these investigations is to observe possible spin-dependent effects beyond two-nucleon forces. When compared to the predictions of Faddeev calculations, based on two-nucleon forces only, significant deviations are observed at all energies and at center-of-mass angles between 70° and 130°. The addition of present-day three-nucleon forces does not improve the description of the data, demonstrating the still insufficient understanding of the properties of three-nucleon systems
Systematic investigation of the elastic proton-deuteron differential cross sectionat intermediate energies
To investigate the importance of three-nucleon forces (3NF) systematically over a broad range of intermediate energies, the differential cross sections of elastic proton-deuteron scattering have been measured at proton bombarding energies of 108, 120, 135, 150, 170, and 190 MeV at c.m. angles between 30° and 170° . Comparisons with Faddeev calculations show unambiguously the shortcomings of calculations employing only two-body forces and the necessity of including 3NF. They also show the limitations of the latest few-nucleon calculations at backward angles, especially at higher beam energies. Some of these discrepancies could be partially due to relativistic effects. Data at lowest energy are also compared with a recent calculation based on χPT .journal articl
Vector and tensor analyzing powers in deuteron-proton breakup at 130 MeV
High-precision data for vector and tensor analyzing powers for the 1H(d,pp)n reaction at a 130-MeV deuteron beam energy have been measured over a large part of the phase space. Theoretical predictions based on various approaches to describe the three nucleon (3N) system reproduce very well the vector analyzing power data and no three-nucleon force effect is observed for these observables. Tensor analyzing powers are also very well reproduced by calculations in almost the whole studied region, but locally certain discrepancies are observed. For Axy such discrepancies usually appear, or are enhanced, when model 3N forces, TM99 or Urbana, are included. Problems of all theoretical approaches with describing Axx and Ayy are limited to very small kinematical regions, usually characterized by the lowest energy of the relative motion of the two protons
Systematic investigation of three-nucleon force effects in elastic scattering of polarized protons from deuterons at intermediate energies
The question, whether the high-quality nucleon-nucleon potentials can successfully describe the three-nucleon system, and to what extent three-nucleon forces (3NFs) play a role, has become very important in nuclear few-body physics. One kinematic region where effects because of 3NFs show up is in the minimum of the differential cross section of elastic nucleon-deuteron scattering. Another observable, which could give an indication about the contribution of the spin to 3NFs, is the vector analyzing power. To investigate the importance of 3NFs systematically over a broad range of intermediate energies, both observables of elastic proton-deuteron scattering have been measured at proton bombarding energies of 108, 120, 135, 150, 170, and 190 MeV, covering an angular range in the center-of-mass system between 30° and 170°. The results show unambiguously the shortcomings of calculations employing only two-body forces and the necessity of the inclusion of 3NFs. They also show the limitations of the results of the present day models for few-nucleon systems at backward angles, especially at higher beam energies. New calculations based on chiral perturbation theory are also presented and compared with the data at the lowest energy
Spin observables in deuteron–proton radiative capture at intermediate energies
A radiative deuteron–proton capture experiment was carried out at KVI using polarized-deuteron beams at incident energies of 55, 66.5, and 90 MeV/nucleon. Vector and tensor-analyzing powers were obtained for a large angular range. The results are interpreted with the help of Faddeev calculations, which are based on modern two- and three-nucleon potentials. Our data are described well by the calculations, and disagree significantly with the observed tensor anomaly at RCNP.journal articl

Caractérisation antibiotypique et biochimique des souches marocaines de Salmonella enteritidis d'origine humaine et alimentaire
L’antibiotypie et la biotypie des souches marocaines de Salmonella enteritidis d’origine humaine et alimentaire ont été investiguées. Cinquante et une souches ont été isolées entre janvier 96 et décembre 97. Parmi les 31 souches humaines, dix souches se sont révélées résistantes aux antibiotiques dont quatre étaient résistantes à plus d’un antibiotique. Parmi les 20 souches alimentaires, onze étaient résistantes dont 6 résistantes à plus d’un antibiotique. Les résultats obtenus montrent une similitude avec les souches méditerranéennes. Les profils biochimiques atypiques étaient rencontrés aussi bien pour les souches alimentaires que pour les souches humaines. L’atypie affecte aussi bien les souches sensibles que les souches résistantes aux antibiotiques. Les caractères atypiques concernent le métabolisme de certains sucres et acides aminés
