Integrally use of native leguminous in the Chaco Region (Argentine) could be an important tool to partially solve underfeeding and environmental problems. The vinal (Prosopis ruscifolia), a very abundant species, was incorporated to an agroforestry model because of its nutritious fruits for both humans and livestock. Whole fruits and fractions (seed, pulp-flour-and residue) were analyzed in samples according to their basic components, fatty acids and mineral. The whole fruits showed a high nutrient level; the pulp flour fraction (13% of the fruit) presented a good protein level (105 g/kg) and lean fat levels (56 g/kg); the seed fraction (16%) contains important protein value (338 g/kg), low fat (59 g/kg) and noticeable fiber content. Calcium showed high levels in seeds (1.53 mg/g) and potassium in flour (9.05 mg/g). Phosphorus level was also important in seeds (4.72 mg/g) although less available because it is present as phytate salts. Vinal fruits have also a predominance of unsaturated fatty acids (50% as linoleic acid).
, conscientes del gran vacío con que en temas de datación absoluta han venido trabajando los investigadores de nuestra comunidad científica. La plasmación en realidad de este objetivo, es decir, el montaje y puesta a punto de un laboratorio de datación absoluta por TL en nuestra Universidad fue posible gracias a la concesión por parte de la D.G.I.C.YT. del proyecto coordinado n.° PB-87-0091, C02-00 el cual de forma muy resumida pretendía tres objetivos básicos: 1. Diseño del equipo experimental. 2. Construcción y puesta a punto de una cadena de TL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
