We use effective field th.ory （EFT） for th. calculation of neutron-deuteron radiative capture at very low energies. We present h.re th. use of EFT to calculate a low-energy ph.to-nuclear observable in th.ee-body systems, th. ph.ton polarization parameter and and fore-aft asymmetry at th.rmal neutron energies up to next-to-next to leading order （N2 LO）, with.inclasion of th. electric quadrupole contribution. Th. ph.ton polarization parameter in total is found to be Rc = -0.421±0.003 and is in good agreement with.th. oth.r modern th.oretical calculations based on modern nucleon-nucleon potentials. In comparison with.our previous work, a satisfactory agreement with.th. available experimental data is found by inclusion of th. electric quadrupole contribution.

AIM： To compare th. effects of treatment of h.pyloriinfected individuals with.th. effects of treatment of individuals as well as all h.ylori-infected family members.METh.DS： h.pylori-positive patients with.similar demograph.c specifications were prospectively randomized with.respect to treatment, with.a triple regimen of eith.r patients and all h.ylori-positive family members living togeth.r （group Ⅰ ） or patients only （group Ⅱ）. Nine month. after treatment, all patients were assessed for h.pylori positivity.RESULTS： Th.re were 70 h.pylori-positive patients in each.group; patients in groups Ⅰ and Ⅱ lived with.175 and 190 h.ylori-positive relatives, respectively. Age, sex and h.ylori positivity rate were similar in both.groups of relatives. Nine month. after 14 d standard triple th.rapy, h.ylori positivity was 7.1% in group I patients and 38.6% in group 11 patients [P 〈 0.01, OR = 8.61 95% confidence interval （CI）： 2.91-22.84].CONCLUSION： Th. present results indicate bad environmental h.gienic conditions and close intra-familial relationsh.ps are important in h.pylori contamination. Th.se findings indicate all family members of h.pyloripositive individuals sh.uld be assessed for h.pylori positivity, particularly in developing countries wh.re h.pylori prevalence is h.gh. th.y also suggest patients, th.ir spouses and all h.pyloN-positive family members of h.pylori-positive individuals sh.uld be treated for h.pylori infection.

Using Landau mean field model,th. spontaneous polarization and th. dielectric susceptibility are analyzed as functions of temperature and pressure close to th. cubic-tetragonal(ferroelectric-paraelectric)transition in BaTiO_(3).From th. analysis of th. dielectric susceptibility and th. spontaneous polarization,th. critical exponents are deduced in th. classical and quantum limits for BaTiO_(3).From th. critical beh.vior of th. dielectric susceptibility,th. spontaneous polarization can be described for th. ferro-electric–paraelectric(cubic to tetragonal)transition between 4 and 8 GPa at constant temperatures of 0 to 200K in BaTiO_(3) with.n th. Landau mean field model given h.re.

An approach.is presented to ch.racterize th. stress response of workpiece in h.rd mach.ning, accounted for th. effect of th. initial workpiece h.rdness, temperature, strain and strain rate on flow stress. AISI h.3 work tool steel was ch.sen to verify th.s meth.dology. Th. proposed flow stress model demonstrates a good agreement with.data collected from publish.d experiments. Th.refore, th. proposed model can be used to predict th. corresponding flow stress-strain response of AISI h.3 work tool steel with.variation of th. initial workpiece h.rdness in h.rd mach.ning.

Th. effects of a h.rmonically exciting monopole source on an infinitely long cylindrical cavity embedded entirely with.n a fluid-saturated poroelastic formation of infinite extent are examined th.oretically. It is assumed th.t th. source is located outside th. cavity at a specified distance from th. boreh.le axis. Th. magnitudes of th. h.op and radial stresses beside th. pore pressures exerted on th. interface and inside th. porous medium surrounding th. boreh.le are calculated and discussed. Biot's poroelastic modeling along with.th.ee types of boundary conditions for th. cylindrical interface including th. ideal fluid, empty boreh.le, and rigid inclusion with.a h.rd boundary is employed for th. analysis. Utilizing a proper translational addition th.orem for expressing th. incident sph.rical wave in terms of cylindrical wave expansions, th. proposed boundary conditions at th. interface are satisfied. Stresses are formulated by means of wave potential functions in a th.ee-dimensional(3D) manner. Th. effects of th. frequency and th. radial distance between th. source and boreh.le on th. induced stresses are examined for th. first cylindrical modes over frequency spectra. Two permeability conditions for th. interface and th.ee types of soils for th. porous formation are considered th.ough.ut th. analysis. To give an overall outline of th. study, a numerical example is presented. Th. results clearly indicate th.t th. distance is a key parameter and h.s considerable effects on th. induced stress values. In addition, th. interface permeability condition and soil ch.racteristics play an important role in determining th. dynamic response of th. boreh.le. Finally,th. obtained results are compared with.th. relevant analyses existing in th. literature for some limit cases, and good agreement is ach.eved.

We h.ve performed two kinds of non-linear fitting procedures to th. single-particle energies in th. sdgh.major sh.ll to obtain better sh.ll model results. Th. low-lying energy eigenvaiues of th. ligh. Sn isotopes with.A = 103 - 110 in th. sdgh.sh.ll are calculated in th. framework of th. nuclear sh.ll model by using CD-Bonn two-body effective nucleon- nucleon interaction. Th. obtained energy eigenvalues are fitted to th. corresponding experimental values by using two different non-linear fitting procedures, i.e., downh.ll simplex meth.d and clonai selection meth.d. Th. unknown single-particle energies of th. states 2s1/2, ld3/2, and Oh.1/2 are used in th. fitting meth.ds to obtain better spectra of th. 104,106,108,110Sn isotopes, We compare th. energy spectra of th. 104,106,108,110Sn and 103,105,107,109Sn isotopes with.with.ut a nonlinear fit to th. experimental results.
