La mayoría de los cultivares tradicionales de papa no están adaptadas a las condiciones del cultivo provocadas por el cambio climático, que hacen disminuir drásticamente los rendimientos e incluso perder completamente la cosecha en muchos lugares desfavorecidos. En países en vías de desarrollo, como en Latinoamérica, esta situación afecta a la base alimentaria de las comunidades, y al sostenimiento económico y social; los agricultores optan por migrar en búsqueda de otros medios de subsistencia.

In the renal function study the diaminodithiol (DADT) complexes with Tc 99m have an advantage due to the great absortion in the kidneys and the fast removal by means of urine. Among this complexes, the N,N´-bis-L-(1-carboxi-2-mercaptoethyl) ethylendiamine (EC) witch form an stable complex with oxotechnetium (V) of tetragonal structure exhibit better results. In this work a study about its preparation is presented.

Medications are a fundamental part of patient care at all stages of their treatment. Magisterial preparations, which are a pharmaceutical product to meet a patient's medical prescription, require adequate management to provide individual safety, which makes it necessary to guarantee that the records corresponding to the production process are reliable and allow their traceability in the attention. The application of information technologies has shown a reduction in medication errors and adverse drug reactions, an impact that has also been documented in electronic prescription. In this study, the steps for the development and implementation of a technological tool through the application of elements of the SCRUM methodology, which allowed optimizing the process of managing medical orders for master mixtures, in a highly complex hospital. reducing times and reducing the risk of errors in t...

Phytoplankton is one of the groups most sensitive to eutrophic conditions, and its disturbance has a potential negative bottom-up effect on lentic ecosystems. In this research we used a multivariate statistics approach (Canonical Correspondence Analysis with a Monte Carlo permutational test) to assess the relationships between nutrient enrichment and the phytoplankton community diversity. Four locations with different levels of eutrophication were sampled at the Bolivian sector of Lake Titikaka. Phytoplankton richness ranged from eight to 16 genera, varying significantly among sites, and its diversity was significantly correlated to nitrogen, phosphorus, and pH (Monte Carlo test, p < 0.05). Phosphorus was determined to be the limiting nutrient in the ecosystem. Community structure assessment showed a non-aggregated distribution of genera among study sites, with few abundant g...
