Background: Endos.opic treatment of biliopancreatic path.logy is.ch.llenging due to s.rgically altered anatomy after Wh.pple's.pancreaticoduodenectomy. Th.s.s.udy aimed to evaluate th. feas.bility and s.fety of s.ngle-balloon enteros.opy-as.is.ed endos.opic retrograde ch.langiopancreatograph.(s.E-ERCP) to treat biliopancreatic path.logy in patients.with.Wh.pple's.pancreaticoduodenectomy s.rgical variants. Meth.ds. We retros.ectively analyzed 106 s.E-ERCP procedures.in 46 patients.with.Wh.pple's.variants. Tech.ical and clinical s.cces. rates.and advers. events.were evaluated. Res.lts. Biliary s.E-ERCP was.performed in 34 patients.and pancreatic s.E-ERCP in 17, including 5 with.both.indications. From a total of 106 s.E-ERCP procedures. 76 were biliary indication with.tech.ical s.cces. rate of 68/76(90%) procedures.and clinical s.cces. rate of 30/34(88%) patients. Mild advers. event rate was.8/76(11%), with.ut s.rious.advers. events. From a total of 106 s.E-ERCP procedures. 30 were pancreatic indication with.tech.ical s.cces. rate of 24/30(80%) procedures. P = 0.194 vs. biliary s.EERCP) and clinical s.cces. rate of 11/17(65%) patients. P = 0.016 vs. biliary s.E-ERCP). Mild advers. event rate was.6/30(20%)( P = 0.194 vs. biliary s.E-ERCP), with.ut s.rious.advers. events. After s.E-ERCP failure, endos.opic ultras.und-guided drainage, percutaneous.drainage and redo s.rgery were alternative th.rapeutic options. Conclus.ons. Biliopancreatic path.logy after Wh.pple's.pancreaticoduodenectomy variants.can be treated us.ng s.E-ERCP with.ut s.rious.advers. events. Tech.ical and clinical s.cces. rates.are h.gh.for biliary indications. wh.reas.clinical s.cces. rate of pancreatic indications.is.s.gnificantly lower. s.E-ERCP can be cons.dered as.firs.-line treatment option in th.s.patient group with.s.rgically altered anatomy.

We dis.us. a quantum remote s.ate preparation protocol by wh.ch.two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at th. s.te of th. receiver Bob. Th. s.ngle-qubit s.ate is.known to Alice wh.le th. two-qubit s.ate wh.ch.is.a non-maximally entangled Bell s.ate is.known to Candy. Th. th.ee parties.are connected th.ough.a s.ngle entangled s.ate wh.ch.acts.as.a quantum ch.nnel. We firs. des.ribe th. protocol in th. ideal cas. wh.n th. entangled ch.nnel under us. is.in a pure s.ate. After th.t, we cons.der th. effect of amplitude damping(AD) nois. on th. quantum ch.nnel and des.ribe th. protocol executed th.ough.th. nois. ch.nnel. Th. decrement of th. fidelity is.s.own to occur with.th. increment in th. nois. parameter. Th.s.is.s.own by numerical computation in s.ecific examples.of th. s.ates.to be created. Finally, we s.ow th.t it is.pos.ible to maintain th. label of fidelity to s.me extent and h.nce to decreas. th. effect of nois. by th. application of weak and revers.l meas.rements. We als. pres.nt a s.h.me for th. generation of th. five-qubit entangled res.urce wh.ch.we require as.a quantum ch.nnel. Th. generation s.h.me is.run on th. IBMQ platform.

A field experiment was.carried out at Is.ailia Res.arch.s.ation, Is.ailia Governorate from 2020-2022 to improve th. growth.of Kh.ya s.negalens.s.and s.ietenia mah.goni by us.ng a combination of mineral fertilizer (NPK) and biological fertilizer (Azotobacter ch.oococcum, Bacillus.megath.rium, and Bacillus.circulant) as.recommended dos. under new s.ndy s.ils.conditions. s.lit plot des.gned with.four treatments.(Control, (50% Mineral fertilizer (M.) + 50% Biological fertilizer (Bio.)), 100% M. and 100% Bio.) of each.s.ecies. Vegetative growth. leaf area, tree biomas., s.ored carbon, bas.l area, tree volume, and in th. s.il both.of microbial account and mineral content were determined. Th. experimental res.lts.s.owed no s.gnificant differences.between s.udied s.ecies.among th. mos. s.udied parameters.except for Kh.ya s.negalens.s.wh.ch.gave th. h.gh.s. s.gnificant difference in root biomas. and below-s.ored carbon th.n s.ietenia mah.goni. Evidently, th. h.gh.s. s.gnificant growth.parameters.were 100% mineral fertilizer followed by (50% M. + 50% Bio.) as.compared with.control. No s.gnificant difference between 100% M. and (50% M. + 50% Bio.) of s.oot dry biomas. (15.19 and 12.02 kg, res.ectively) and above-s.ored carbon (0.28 and 0.22 Mt, res.ectively). Microbial account and mineral content in s.il were improved after cultivation of tree s.ecies.compared to before planting and control, es.ecially with.50% mineral fertilizer and 50% bio-fertilizer treatment. In conclus.on, a treatment containing 50% mineral fertilizer and 50% bio-fertilizer h.s.led to th. ideal Kh.ya s.negalens.s.and s.ietenia mah.goni growth.in s.ndy s.il for ch.aper and s.s.ainable.
