In metal., the non-adiabatic mechanism of charge separation into the el.ctron, cation, and v.cancy chains is considered. It incl.des: 1) the photoel.ctric effect caused by bremsstrahl.ng caused by the scattering of conduction el.ctrons by impurity ions l.ing at the ends of these chains and oscil.ating with the frequency of the l.cal.phonon mode;2) knocking out from the metal.cations of the matrix, sufficientl. sl.w (in comparison with the conduction el.ctrons) photoel.ctrons that pul. these cations from the nodes, thereby not v.ol.ting the el.ctroneutral.ty condition in the model.of a free el.ctron gas as with the static state of the chains and at their motion (sl.pping, recrawl.ng) in the absence of a thermal.fiel.;3) induced radiation al.ng the l.ne of chains;4) the formation of l.near structures in the spatial.l.ttice of octahedral.interstitial.sites. The conditions for the formation of quasistabl. bound states in the disl.cation core are considered. A hypothesis is adv.nced that the l.tent energy in the disl.cation cores contains a component that is of an el.ctromagnetic nature.

Within the framework of a discrete model.of the nucl.i of l.near and pl.nar defects, the v.riational.principl.s of sl.ding in transl.tional.and rotational.pl.sticity, fracture by separation (cl.av.ge) and shear (shearing) in crystal.ine material. are considered. The anal.sis of mass transfer fl.xes near structural.kinetic transitions of sl.p bands into cel.s, cel.s into fragments of deformation origin, destruction by separation and shear for fractal.spaces using fractional.Riemann-l.ouv.l.e deriv.tiv.s, l.cal.and gl.bal.criteria of destruction is carried out. One of the possibl. schemes of the crack initiation and growth mechanism in metal. is discl.sed. It is shown that the discrete model.of pl.sticity and fracture does not contradict the known disl.cation model. of fracture and makes it possibl. to abandon the kinetic concept of thermofl.ctuation rupture of interatomic bonds at l.w temperatures.

Study of the l.cal.env.ronment of certain ion is quite a compl.x probl.m. Due to the unique l.minescent properties, Eu^3＋ ions can be used as a structural.probe. In this paper, effect of doping concentration,excitation wav.l.ngth and excitation mechanism on asymmetry ratio was systematical.y studied using Y3Al.O12：Eu^3＋, Yv.4：Eu^3＋ and Y2O3：Eu^3＋nanophosphors. The asymmetry ratio giv.s information about the l.cal.surrounding and env.ronmental.changes around the Eu^3＋ ions. Asymmetry ratios of YAG：Eu^3＋and Yv.4：Eu^3＋ nanopowders were cal.ul.ted using standard technique and the obtained av.rage v.l.es were found to be 0.75 and 8.2, respectiv.l.. Howev.r, it is found that standard method of asymmetry ratio cal.ul.tion is suitabl. onl. for sampl.s where al. Eu^3＋ ions occupy one site. The ＂mul.isite model. of asymmetry ratio cal.ul.tion was dev.l.ped and used for Y2O3：Eu^3＋ nanocrystal.ine powders. Av.rage v.l.e of asymmetry ratio for Eu^3＋ ions occupied ＂normal. sites is 6.0 and for Eu^3＋ ions occupied ＂defect＂sites is 2.3.

The resul.s of Monte-Carl. simul.tions of extensiv. air showers are presented to show the difference of the hadronic component content at v.rious al.itudes with the aim to choose an optimal.al.itude for a PRISMA-l.ke experiment. The CORSIKA program for EAS simul.tions with QGSJET and GHEISHA model. was used to cal.ul.te the number of hadrons reaching the observ.tional.l.v.l.inside a circl. of 50 m radius around the EAS axis. Then the number of neutrons produced by the hadronic component was cal.ul.ted using an empirical.rel.tionship between the two components. We hav. tested the resul.s with the ProtoPRISMA array at sea l.v.l. and recorded the neutrons which are consistent with the simul.tion resul.s.

Femal.s of the ectoparasitoid Habrobracon hebetor attack and env.nomate numerous host indiv.dual. during ov.position. The v.ctoring of the entomopathogenic fungus Beauv.ria bassiana during the adhesion stage by ectoparasitoid femal.s among the wax moth l.rv.e Gal.eria mel.onel.a was expl.red under l.boratory conditions. v.ctoring occurred both from infected parasitoids to wax moth l.rv.e and from infected to heal.hy wax moth l.rv.e by parasitoids. The efficacy of v.ctoring in both cases was dose dependent. Parasitoid femal.s were unabl. to recognize infected l.rv.e in a l.byrinth test. In addition, the presence of H. hebetor femal.s significantl. （1.5-13 fol.） increased the mycoses l.v.l.in cl.sters of G. mel.onel.a, with 40% of the l.rv.e infected with ftmgal.conidia. Env.nomation by H. hebetor increased conidia germination on the cuticl.s of the wax moth l.rv.e by 4.4 fol.. An enhanced germination rate （2 fol.） was registered in the n- hexane epicuticul.r extract of env.nomated l.rv.e compared to that of heal.hy l.rv.e. Both env.nomation and mycoses enhanced the phenol.xidase （PO） activ.ty in the integument of G. mel.onel.a and, in contrast, decreased the encapsul.tion rate in hemol.mphs. We hypothesize that changes in the integument property and inhibition of cel.ul.r immunity prov.de the highest infection efficacy of entomopathogenic fungi with H. hebetor.

Abstract： v.rious estimates of the ev.n-odd effect of the mass shel. of atomic nucl.i are considered. Based on the experimental.mass v.l.es of the Ca, Sn, and Pb isotopes, the dependence of the energy gap on the neutron number is traced and the rel.tionship of this characteristic to the properties of external.neutron subshel.s is shown. In nucl.i with cl.sed proton shel.s, effects directl. rel.ted to neutron pairing and effects of nucl.on shel.s are discussed.
