SELENIO: ASPECTOS RELEVANTES DE SU QUÍMICA E IMPORTANCIA BIOLÓGICA by Gómez Castaño, Jovanny Arlés

“…Palabras clave: Selenio, Química seleno-orgánica, Químicaseleno-inorgánica, selenoproteínas AbstractThroughout its already almost 200 years of scientific live,Selenium has changed to be an element classified almostexclusively as a poison to be an important substance withrelevant uses in chemistry, biology, medicine and even in theindustry. The different reactivity of compounds of Seleniumin contrast to its less heavy chalcogen analogs (oxygenand sulfur) has allowed the development of new syntheticmethods, both in organic and inorganic chemistry. …”

Stigmatic receptivity and hybridization in cowpea beans (Vigna unguiculata L. (Walp.)) by Araméndiz-Tatis, Hermes, Cardona-Ayala, Carlos, Espitia-Camacho, Miguel, Hernández-Murillo, Jenry Rafael

“…Classic plant breeding, based on the selection of superior individuals and directed crosses, led to the need-to-know aspects of the floral biology of cowpea beans. The research was carried out at the Universidad de Córdoba, Colombia, through two experiments: in the first, stigmatic receptivity was evaluated as response time to hydrogen peroxide, under a randomized complete block design, with a 3×4 factorial arrangement (three genotypes: Caupicor 50, Missouri and BRS Milenium, and at four hours of the day: 7:00 and 9:00 AM; 3:00 and 5:00 PM) and three replications. …”

Didactic strategy for the learning of biogeochemical cycles from transdiscipl inarity by Ruíz Martínez, Alexandra

“…As for the integration of the subject and the selection of the sample it was made between the so-called hard sciences like Chemistry, with soft disciplines like Biology. Finally, for the implementation, two groups of students of the same grade of secondary education were formed, but with different conditions each other; Then the measuring instrument was performed, pretest and posttest; Then some observations of the field work were recorded and a survey was applied to assess the satisfaction of the project.…”
