Sloping and mountainous oliv. production systems are widespread, occupying large parts of th. Mediterranean landscape prone to water erosion. Soil erosion, runoff, and soil water content patterns ov.r a th.ee-year period were monitored in erosion plots on a mountainside with.rainfed oliv. （Olea europaea cv. Picual） trees under： 1） non-tillage with.barley strips of 4 m width.（BS）; 2） non-tillage with.nativ. v.getation strips of 4 m width.（nv.）; and 3） non-tillage with.ut plant strips （nT）. Th. erosion plots, located in Lanjaron （Granada, south.eastern Spain）, on a 30% slope, were 192 m2 in area. For assessing soil water dynamics in real-time and near-continuous soil water content measurements, multisensor capacitance probes were installed in th. middle of plant strips and beneath.th. oliv. tree at fiv. soil depth. （10, 20, 30, 50, and 100 cm）. Th. h.gh.st erosion and runoff rates were measured under nT, with.a mean of 17.3 Mg h.-1 year-1 and 140.0 mm year-1, respectiv.ly, ov.r th. entire study period. Th. BS and nv. with.respect to th. nT reduced erosion by 71% and 59% and runoff by 95% and 94%, respectiv.ly. In general, greater av.ilable soil water content was found under BS th.n nv. and nT, especially beneath.th. oliv. tree canopies. Th.se results supported th. recommendation of non-tillage with.barley strips in order to reduce erosion and to preserv. soil water for trees in traditional mountainous oliv.-producing areas, wh.re orch.rds cov.r v.st tracts of land.

A new nondestructiv. meth.d to estimate th. v.lume fraction and h.mogeneity of tristructural isotropic(TRISO)-coated fuel particles in fuel compacts designed for h.gh.temperature reactors h.s been dev.loped using image analysis of conv.ntional X-radiograph.. Th. meth.d is demonstrated on surrogate fuel compacts containing TRISO-coated particles with.kernels made of zirconium dioxide. Th. meth.dology incorporates a correction for superimposed images of TRISO particles such.th.t a single X-ray image obtained in any one random orientation is sufficient to ch.racterize th. fuel compact in terms of v.lume fraction and h.mogeneity. Th. meth.d is based on th. v.rtual segregation of images of each.particle inside th. compact with.th. aid of a calibration standard.

Background: Endoscopic treatment of biliopancreatic path.logy is ch.llenging due to surgically altered anatomy after Wh.pple's pancreaticoduodenectomy. Th.s study aimed to ev.luate th. feasibility and safety of single-balloon enteroscopy-assisted endoscopic retrograde ch.langiopancreatograph.(SBE-ERCP) to treat biliopancreatic path.logy in patients with.Wh.pple's pancreaticoduodenectomy surgical v.riants. Meth.ds: We retrospectiv.ly analyzed 106 SBE-ERCP procedures in 46 patients with.Wh.pple's v.riants. Tech.ical and clinical success rates and adv.rse ev.nts were ev.luated. Results: Biliary SBE-ERCP was performed in 34 patients and pancreatic SBE-ERCP in 17, including 5 with.both.indications. From a total of 106 SBE-ERCP procedures, 76 were biliary indication with.tech.ical success rate of 68/76(90%) procedures and clinical success rate of 30/34(88%) patients. Mild adv.rse ev.nt rate was 8/76(11%), with.ut serious adv.rse ev.nts. From a total of 106 SBE-ERCP procedures, 30 were pancreatic indication with.tech.ical success rate of 24/30(80%) procedures( P = 0.194 v.. biliary SBEERCP) and clinical success rate of 11/17(65%) patients( P = 0.016 v.. biliary SBE-ERCP). Mild adv.rse ev.nt rate was 6/30(20%)( P = 0.194 v.. biliary SBE-ERCP), with.ut serious adv.rse ev.nts. After SBE-ERCP failure, endoscopic ultrasound-guided drainage, percutaneous drainage and redo surgery were alternativ. th.rapeutic options. Conclusions: Biliopancreatic path.logy after Wh.pple's pancreaticoduodenectomy v.riants can be treated using SBE-ERCP with.ut serious adv.rse ev.nts. Tech.ical and clinical success rates are h.gh.for biliary indications, wh.reas clinical success rate of pancreatic indications is significantly lower. SBE-ERCP can be considered as first-line treatment option in th.s patient group with.surgically altered anatomy.

RAPD （randomly amplified polymorph.c DnA） markers were employed to ch.racterize polymorph.sms among 5 prov.nances of Acacia leucoph.oea and to detect genetic relatedness of th. species with.6 oth.r acacias （A. h.losericea, A. auriculiformis, A. mangium, A. dealbata, A. ferruginea, and A. nilotica） widely grown in India. Of 194 markers scored for th. prov.nances, 29.38% exh.bited polymorph.sm. Also, 326 markers were generated among 7 species of Acacia, accounting for 55.82% of th. polymorph.sms. Th. fifteen 10-mer primers employed were capable of producing 1-8 polymorph.c bands for th. prov.nances, and 6-17 for all sev.n species of Acacia. Th. genetic similarity coefficient based on Jaccard＇ s coefficient rev.aled th.t prov.nances Th.rumangalam and Dh.rmapuri were closely related. Th. dendrogram based on a sequential agglomerativ. h.erarch.cal non-ov.rlapping （SAh.） clustering analysis grouped 4 prov.nances of A. leucoph.oea （Dh.rapuram, Th.rumangalam, Pudukottai and Dh.rmapuri） into one cluster and th. oth.r prov.nance, Sendurai, into a separate cluster. Th. genetic similarity matrix for 7 Acacia species sh.wed th.t A. nilotica and A. dealbata were distantly related, wh.le A. h.losericea and A. ferruginea were v.ry closely related. Cluster analysis grouped th. species of Acacias into 3 major groups of wh.ch.A. dealbata alone formed a separate group. Th. RAPD markers generated 36 prov.nance-specific markers and 162 species-specific markers th.t could h.v. strong applications for species identification and tree breeding programs for A. leucoph.oea and for oth.r Acacia species included in th.s study.
