U.S. US 4421881 A 20 Dec 1983,7 pp. Cont.-in-part of U.S. Ser. No. 246,836, abandoned. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08L001-18; C08L089-06; C08J003-20. NCL: 524024000. APPLICATION: US 82-369379 19 Apr 1982. PRIORITY: US 81-246836 23 Mar 1981. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Fingernail polishes contain nitrocellulose as primary film former, 32 secondary film formers including an acrylic copolymer, a H2O-sol. gelatin (av. mol. wt. 50,000-70,000, 50-80% from bone and 20-50% from hide), plasticizer, and solvents. The lacquer contains 0.25-1% gelatin and 1-4% of the acrylic copolymer. The nitrocellulose, gelatin plasticizer, and lacquer solvents are kneaded under pressure to give a solid dispersion of gelatin in nitrocellulose. A lacquer contained nitrocellulose RS 1/2 s. 17.50, toluenesulfonamide-formaldehyde copolymer 7.50, gelatin (type B, av. mol. wt. 62,000-73,000, 70% bone, 30% hide) 0.60, di-Bu phthalate 5.00, acrylic copolymer 2.00, camphor 0.55, BuOAc 17.50, EtOAc 7.50, iso-PrOH 5.00, BuOH 0.55, UV absorber 0.05, and toluene 36.25%. The gelatin and 5.4 g nitrocellulose, and 1.8 g di-Bu phthalate and some of the solvents were blended in a high-shear mixer, and the high-viscosity liq. was cycled through a roller mill until thoroughly dispersed. The mixt. was dispersed with 30% of the total solvents and added to a lacquer base made by adding the rest of the nitrocellulose to the remaining solvents, followed by the toluenesulfonamide-formaldehyde resin, the rest of the plasticizer, UV absorber, and camphor, filtering, and adding the acrylic polymer. The nail polish had better wear and chip resistance that similar products with the acrylic polymer and/or gelatin.

Proteic and isoenzymic characterization of the pathovars of Xanthomonas campestris which attack cassava

Proteic and isoenzymic characterization of the pathovars of Xanthomonas campestris which attack cassava. Kimura, Osamu; Dianese, Jose Carmine (Dep. Fitopatol., Univ. Fed. Rural Rio de Janeiro, Seropedica CEP 23560, Brazil). Pesqui. Agropecu. Bras., 18(11), 1215-28 (Portuguese) 1983. CODEN: PEABBT. ISSN: 0079-1121. DOCUMENT TYPE: Journal CA Section: 10 (Microbial Biochemistry) Electrophoretic profiles of sol. protein, esterase, acid phosphatase, alk. phosphatase, and glucose 6-phosphate dehydrogenase were detd. for 11 isolates of X. campestris pv. manihotis, 3 isolates of X. campestris pv. cassavae, and 1 isolate of X. campestris pv. campestris. Esterase and acid phosphatase were more useful in characterizing the pathovars of X. campestris from cassava than total protein, alk. phosphatase, or glucose 6-phosphate dehydrogenase. Phylogenic relations were established leading to differentiation of a South American isolate from 2 African strains of X. campestris cassavae. The similarity in isozymic patterns of the South American isolate of X. campestris cassavae and those of some isolates of X. campestris manihotis suggests that the former could be a yellow strain of X. campestrtris manihotis. 9013-79-0 and 9001-40-5 are just another two chemicals used in this study. The isolates of X. campestris manihotis could be grouped according to pathogenicity by analyzing their profiles of acid phosphatase. .
