A pesar que la investigación para comunicar o diseñar estrategias de comunicación es la clave para conocer y entender la realidad y delinear las estrategias que permitan transformarla, constatamos que cada vez decrece el interés por cultivarla y los recursos públicos y privados que se destinan para ello son cada vez más escasos.

Most main issues on the Development and Communication for Development Agenda remain the same, but new scenarios, new cooperation partnerships, new issues and new players have arisen thus reshaping the world in this new century and posing new concerns and challenges. In order to face such challenges, promoting building a culture for development to be sustained on the basis of an inclusive democracy with active citizenship guaranteeing governance is important.

The study was conducted in a low terrace forest flooded by sewage in the native community of Huancayo – Nucuray River, Lagunas district, Alto Amazonas province, Loreto department. Forest tree species with dbh >= 30 cm were evaluated in 26 sampling units of half a hectare. A total of 779 trees, 25 forest species, 23 genera, and 12 botanical families were recorded. The most abundant families were Fabaceae (28.5%), Malvaceae (18.1%), and Myristicaceae (17.1%). The density was 33.87 trees/ha, calculated on a total of 779 trees in 26 units of 0.5 ha. Four dominant species accounted for more than 50% of the total IVI: Virola elongata, Copaifera reticulata, Ceiba samauma, and Myroxylon balsamum. The forest presented a medium-low diversity. (Shannon-Wiener (H'): 2.29; Simpson (1 D): 0.888; and Margalef: 1.9). It is recommended to develop sustainable forest management plans focused on Virola el...

The intention of the present article is not to expose a definitive and general work on the subject of the radio policies in Peru, but to make a first approximation to this matter centering it in the decade of the eighties.

The presence of secondary metabolites and of chromium element in seven medicinal plants empirically used for their hypoglycemic action by a phytochemical screening and a qualitative method and other one that is quantitative by Atomic Absorptioli. Spectroscopy for detelmining trivalent chromium has been researched. The studied species are: Phyllantus niruri L. (Chancapiedra), Geranium dielsianum Knut (Pasuchaca), GentianeIla alborosea G. (Hercampure), Otholobium pubescells (Culén), Smallantus sonchifolia (Yacón), Chloraphora tincoria (Mora) y Taraxacum officinalis W (Diente de león). It was phytochemically determined the presence of the following secondary metabolites: alkaloids, flavonoids , tannins, saponins and glycosides, by means of color and precipitation reagents. The determination of chromium element was carried out by qualitative and quantitative via. The accomplished study co...
