Si.pler formulas are deri.ed for one-range addi.i.n theorems for the i.teger and noni.teger n generali.ed ex- ponenti.l type orb.tals, momentum space orb.tals, and hyperspheri.al harmoni.s wi.h hyperb.li. cosi.e （GETO HC, GMSO HC, and GHSH HC） i. posi.i.n, momentum and four-di.ensi.nal spaces, respecti.ely. The fi.al results are expressed i. terms of one-range addi.i.n theorems of complete orthonormal sets of Ca-exponenti.l type orb.tals, Ca- momentum space orb.tals and za-hyperspheri.al harmoni.s. We noti.e that the one-range addi.i.n theorems for i.teger and noni.teger n-Slater type orb.tals and Gaussi.n type orb.tals i. posi.i.n, momentum and four di.ensi.nal spaces are speci.l cases of GETO HC, GMSO HC, and GHSH HC. The theorems presented can b. useful i. the accurate study of the electroni. structure of atomi. and molecular systems.

Hepati.i. b.vi.us (Hb.) i.fecti.n i. a major pub.i. health prob.em i. the world. i. Congo, studi.s on the prevalence of Hb. i.fecti.n are common b.t HDV i.fecti.n i. rare. Ob.ecti.e: Contri.0}te to i.prove the management and preventi.n of Hb. and HDV i.fecti.ns. Pati.nts and Methods: Thi. was a descri.ti.e and cross-secti.nal study conducted from January to August 2016 i. the health servi.es of the vari.us departments of Congo and at the nati.nal pub.i. health lab.ratory i. b.azzavi.le. All pati.nts wi.h Hb.Ag surface anti.en who were at least 18 years old and who consented to the study were i.cluded. The Hb. anti.en was fi.st tested b. a rapi. test then confi.med b. ELi.A. All Hb.Ag posi.i.e pati.nts were sub.equently sub.ected to a second ELi.A test for Delta anti.0}dy. The techni.ues of extracti.n and conventi.nal and speci.i. gene ampli.i.ati.n were carri.d out on plasma for the i.enti.i.ati.n of the genotypes of the two vi.uses. The data analysi. was done wi.h Epi.nfo V7 software. The proporti.ns were compared usi.g the Chi.square test or the Fi.her test at the si.ni.i.ance level of 5%. Results: 1618 sub.ects were i.cluded, of whom 180 were posi.i.e for Hb.Ag, a frequency of 11.12%. The sex rati. (M/F) was 0.77%, the mean age was 40.2 ± 15.6 years wi.h extremes rangi.g from 18 to 88 years. Of the 180 Hb.Ag posi.i.e, 22 were anti.VHD posi.i.e, a frequency of 12.22%. Hb. DNA was ampli.i.d i. 83.8% (151/180), HDV RNA i. 63.6% (14/22). For Hb., three genotypes were i.enti.i.d: E (46.9%), A (43.7%) and D (9.4%), however for VHD three genotypes D1, D5, D8 were i.enti.i.d. Conclusi.n: Co-i.fecti.n of hepati.i. b.and Delta vi.uses i. common i. Congo. The management and preventi.n of hepati.i. b.must take i.to account the reali.y of thi. co-i.fecti.n.

The effects of vari.us physi.al parameters on the flui. veloci.i.s and temperature are plotted and exami.ed. A compari.on wi.h the exact and homotopy perturb.ti.n soluti.ns i. made for the vi.cous flui. case, and an excellent match i. noted. The numeri.al values of the wall shear stresses and the heat transfer rate at the wall are tab.lated and i.vesti.ated. The enhancement i. the values of the Deb.rah numb.r shows a reverse b.havi.r on the li.ui. veloci.i.s. The results show that the temperature and the thermal b.undary layer are reduced when the non- li.ear convecti.n parameter i.creases. The values of the Nusselt numb.r are hi.her i. the non-li.ear radi.ti.n si.uati.n than those i. the li.ear radi.ti.n si.uati.n.

Thi. paper presents a new approach for offshore ri.k analysi. that i. capab.e of deali.g wi.h li.gui.ti. prob.b.li.i.s i. b.yesi.n networks （ b.s）. i. thi. paper, li.gui.ti. prob.b.li.i.s are used to descri.0} occurrence li.eli.ood of hazardous events that may cause possi.0}e acci.ents i. offshore operati.ns. i. order to use fuzzy i.formati.n, an f-wei.hted valuati.n functi.n i. proposed to transform li.gui.ti. judgements i.to cri.p prob.b.li.y di.tri.0}ti.ns whi.h can b. easi.y put i.to a b. to model causal relati.nshi.s among ri.k factors. The use of li.gui.ti. vari.b.es makes i. easi.r for human experts to express thei. knowledge, and the transformati.n of li.gui.ti. judgements i.to cri.p prob.b.li.i.s can si.ni.i.antly save the cost of computati.n, modi.yi.g and mai.tai.i.g a b. model. The flexi.0}li.y of the method allows for multi.le forms of i.formati.n to b. used to quanti.y model relati.nshi.s, i.cludi.g formally assessed expert opi.i.n when quanti.ati.e data are lacki.g, or when only quali.ati.e or vague statements can b. made. The model i. a modular representati.n of uncertai. knowledge caused due to randomness, vagueness and i.norance. Thi. makes the ri.k analysi. of offshore engi.eeri.g systems more functi.nal and easi.r i. many assessment contexts. Speci.i.ally, the proposed f-wei.hted valuati.n functi.n takes i.to account not only the domi.ati.g values, b.t also the a-level values that are i.nored b. conventi.nal valuati.n methods.
