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.

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.
