A finite element (FE) analysis of tensile test for a welded joint of austenitic stainless steel for a building structure SUS304A predicts necking in the weld metal as well as lower tensile strength ...than that of the base metal, even though the joints has the strength-overmatched weld metal. The FE analytical studies also suggest that such an anticipated deformation behavior comes from large difference in uniform elongation between the base metal and the weld metal. Experimental works for overmatched welded joints using SUS 304A and welding wire TS308MoJ supports the joint strength and the necking behavior demonstrated by the FE analysis. On the basis of parametric FE analyses, mechanical parameters that should be controlled to ensure the base metal necking and the tensile strength of a base metal in tensile test of the overmatched joint are proposed.

Villous adenomas of the urinary tract are rare as compared to urothelial carcinoma. We report a case of urinary bladder villous adenoma in a 90-year-old woman. Cystoscopic examination revealed a ...papillary tumour in the diverticulum at the posterior wall of the urinary bladder. Transurethral resection was performed and histopathological examination revealed predominantly tubulovillous architecture, and showed an identical immunohistochemical profile to villous adenoma associated with cystitis glandularis.
The tensile test results for welded joiut of Austenitic staiuless steel for buildiug structure SUS304A usiug weldiug wire TS308MoJ show failure in the weld metal and lower teusile strength than base ...metal, whereas the joints exhibit strength overmatch in weld metal. FE-analytical studies demonstrate that those failure behaviors come from the large difference in uniform elongation between the base metal and the weld metal. The mechanical parameters which should be controlled to ensure a failure in a base metal and tensile strength of a base metal for a tensile specimen of the overmatched joint are proposed.
In the 2-amino-6-substituted-9-β-D-ribofuranosylpurines series, 6-hydrazino (VI), 6-methylhydrazino (VIII), 6-hydroxylamino (VII), 6-methylamino (X), and 6-dimethylamino (XI) derivatives were ...synthesized by condensation of 6-alkylthioguanosines with respective amines. VI and VII were reduced with Raney nickel to 2, 6-diamino derivative (IX). Similarly, VIII was also reduced with Raney nickel to X.
