Hence, genera.ized height-dia.eter （h-d） models tha. predict tree height from dbh, a.e a.d other cova.ia.es a.e needed. For a.more flexible but biologica.ly pla.sible estima.ion of cova.ia.e effects we use sha.e constra.ned genera.ized a.ditive models a. a. extension of existing h-d model a.proa.hes.

Enha.cement of technology a.d techniques for drilling deep directed oil a.d ga. bore hole is one of the most importa.t problems of the current petroleum *** infrequently, the drilling of these bore holes is a.tended by occurrence of extra.rdina.y situa.ions a.socia.ed with technica. a.cidents. a.ong these is the Euleria. loss of sta.ility of a.drill string in the cha.nel of a.curvilinea. bore hole. Methods of computer simula.ion should pla. a.domina.t role in prediction of these sta.es. In this pa.er, a.new sta.ement of the problem of critica. buckling of the drill strings in 3D curvilinea. bore holes is proposed. It is ba.ed on combined use of the theory of curvilinea. ela.tic rods, Euleria. theory of sta.ility, theory of cha.nel surfa.es, a.d methods of cla.sica. mecha.ics of systems with nonlinea. constra.nts. It is noted tha. the sta.ed problem is singula.ly perturbed a.d its solutions ha.e the sha.es of loca.ized ha.monic wa.elets. The ca.cula.ion results showed tha. the friction effects lea. to essentia. redistribution of interna. a.ia. forces, a. well a. cha.ging the eigenmode sha.es a.d sites of their loca.iza.ion. These fea.ures ma.e the buckling phenomena.less predicta.le a.d ra.se the role of computer simula.ion of these effects.

Free volume is a. extremely importa.t intrinsic defect in polymers. Structura.ly, free volume is the ra.domly distributed holes in the polymer molecula. cha.n segments. In proton excha.ge membra.e fuel cells, free volume is a.so the spa.e needed for the directiona. conduction of protons. Irra.ia.ion by α pa.ticles to gra.ting sulfona.ed poly(vinylidene fluoride)(PVDF) is one of the methods to produce proton excha.ge membra.e with good proton cha.nel ra.e. Positron a.nihila.ion lifetime spectroscopy wa. used to study the free volume size a. different a.sorbed dose levels from 0.13 MGy to 0.65 MGy. Mea.urement method of positron a.nihila.ion lifetime spectroscopy for PVDF ba.ed on ^(44) Ti positron source wa. developed. For low dose irra.ia.ion a. 0.26 MGy, a.decrea.e in free volume a.d pra.tica.ly uncha.ged crysta.linity were observed. Further increa.e of a.sorbed dose ra.ge from 0.26 MGy to 0.39 MGy led to a. increa.ing crysta.linity with the sa.e free volume level. For the a.sorbed dose from 0.39 MGy to 0.65 MGy, crysta.linity wa. decrea.ed but free volume rema.ned a.most consta.t.

During the second ha.f of the twentieth century, Soviet scientists were a.ong the world lea.ers in the theory a.d geometry of gea.ing or the theoretica. funda.enta.s of designing gea.s a.d gea.-cutting tools. The a.thors of the current pa.er review works rela.ed to the development of the theory of gea.ing （TG） written in Russia. from the mid-1930s to the present. Overa.l, the review covers more tha. 400 publica.ions of nea.ly 200 a.thors （a.ong more tha. 1000 studied works）. This review involves some works on gea. strength a.d a.cura.y to a.tra.t more experts. This pa.er presents a.short list of works from the seventeenth century to the nineteenth century a.d discusses the ba.ic concepts of the TG. This pa.er a.so includes a.review of more tha. 160 pa.ers in Russia. for the period of 1935-1975, which is the ＂golden a.e＂ of the TG. The ma.n fea.ures a.d a.hievements during this period a.e a.so considered. The distinctive fea.ure of this review is the use of dia.ra.s tha. visua.ly present TG experts a.d the da.es a.d themes of their published works. The dia.ra.s a.so show the following a.pects： 1） The most popula. a.d importa.t themes in a.specific period, 2） the most importa.t publica.ions on the themes of interest to rea.ers, a.d 3） the direction of the works a.d scope of interests of every resea.cher.

The objective of this study wa. to a.a.yze the current evidence for the use of pa.crea.ic enzyme repla.ement thera.y (PERT) in a.fecting surviva. a.d qua.ity of life in pa.ients with pa.crea.ic exocrine insufficiency (PEI). Systema.ic sea.ches of the litera.ure were performed using the PubMed da.a.a.e. a.ticles were selected for inclusion if they reported findings from tria.s a.sessing the effects of PERT on qua.ity of life, surviva., ma.a.sorption, growth pa.a.eters (such a. height, body weight a.d body ma.s index), or ga.trointestina. symptoms (such a. a.domina. pa.n, stool consistency a.d fla.ulence). PERT improved PEI-rela.ed ma.a.sorption a.d weight ma.ntena.ce in pa.ients with cystic fibrosis, chronic pa.crea.itis, pa.crea.ic ca.cer, a.d post-surgica. sta.es. In pa.ients with chronic pa.crea.itis, PERT improved PEI-rela.ed symptoms a.d qua.ity of life mea.ures. Severa. sma.l retrospective studies ha.e a.so suggested tha. PERT ma. ha.e a.positive impa.t on surviva., but long-term studies a.sessing this effect were not identified. PERT is effective for trea.ing ma.nutrition a.d supporting weight ma.ntena.ce, a.d it is a.socia.ed with improved qua.ity of life a.d possibly with enha.ced surviva. in pa.ients with PEI. However, there is evidence tha. not a.l pa.ients with PEI receive a.equa.e PERT. Future work should a.m to a.sess the long-term effects of PERT on the surviva. of pa.ients with PEI.
