Scientific research is considered one of the key processes of university management, whose mission is to promote the sustained growth of science and technological innovation in each institution, in a way that allows it to achieve national and international recognition, while at the same time strengthen the university-society link, hence the need to systematically monitor its impact. The objective of the present work was the development of an index to measure the pertinence and scientific impact of the research results of Cuban universities, as a basis for evaluating their management. To this end, a methodology was conceived that integrated qualitative and quantitative methods. As a result, indexes were obtained to assess the pertinence and contributions made to scientific impact by publications, awards, intellectual property and scientific training; as well as a general index that allows measuring the pertinence and the scientific impact. The calculation of all of them was automated through a calculus sheet of Excel. It was concluded that the use of the proposed methodology provides a valuable tool to systematically monitor the pertinence and scientific impact of the research results.

The article presents an analysis on the science results and innovation obtained in the University of Oriente during the period 2011 at the 2015. The investigation, of exploratory character, combines quantitative and qualitative methods, to determine the main difficulties related with the behavior of this results. The derived conclusions of the analysis indicate that they exist inadequacies that have their base in the form in that has been developed the administration of the process of scientific investigation and their evaluation, during that period, revealing opportunities for a methodological intervention in this administration.

Las universidades necesitan identificar espacios de superación y oportunidades de desarrollo profesional para sus profesores e investigadores, así como plataformas de intercambio de saberes en las que resulte provechoso estar representadas, en aras de mejorar sus resultados y contribuir a los procesos de optimización de las políticas científicas y de gestión de la investigación. Una vía para lograrlo la ofrecen los rankings internacionales de universidades, instrumentos útiles para evaluar la visibilidad de los resultados universitarios. El objetivo del presente trabajo es establecer pautas para avanzar en el posicionamiento de las universidades cubanas en los rankings internacionales. Para ello se aplicó una metodología que permitió articular los indicadores de estos rankings con los patrones de calidad de la Junta de Acreditación Nacional. PALABRAS CLAVE: ranking de universidades, evaluación, acreditación, indicadores, posicionamiento. RESUMO As universidades precisam identificar aprendizagem espaça e oportunidades de profissional de desenvolvimento para os professores deles e investigadores, como também plataformas de troca de conhecimento nesses que são lucrativos ser representado, por causa de melhorar os resultados deles e contribuir aos processos de otimização das políticas científicas e de administração da investigação. Uma estrada para alcançar isto oferece os rankings internacionais de universidade, instrumentos úteis para avaliar a visibilidade dos resultados universitários. O objetivo do trabalho presente é estabelecer regras para avançar no posicionamento das universidades cubanas em rankings internacionais. Para isto era aplicado isto uma metodologia que permitiu articular os indicadores destes rankings com os padrões de qualidade do Junta de Credenciamento Nacional. PALAVRAS-CHAVE: ranking de universidades; avaliação; credenciamento; indicadores; posicionamento. International university rankings. Alternative to advance in the positioning of Cuban institutions ABSTRACT The universities need to identify learning spaces and opportunities of development professional for their professors and investigators, as well as platforms of exchange of knowledge in those that is profitable to be represented, for the sake of to improve their results and to contribute to the processes of optimization of the scientific politicians and of administration of the investigation. A road to achieve it offers it the international rankings of universities, useful instruments to evaluate the visibility of the university results. The objective of the present work is to establish rules to advance in the positioning of the Cuban universities in international rankings. For it was applied it a methodology that allowed to articulate the indicators of these rankings with the patterns of quality of the Junta of National Accreditation.

La adsorción y/o formación de complejos de metales pesados basados en la actividad química de la biomasa, es el proceso conocido como biosorción y es la base de una nueva tecnología para su remoción en efluentes industriales y su posterior recuperación. En esta tecnología se pueden utilizar diferentes tipos de biomasas tales como: algas, microorganismos y sub-productos agrícolas. Este trabajo estudió la adsorción de Cr(VI) utilizando la cáscara del fruto de la planta Cocos nucífera L. como biomasa orgánica. Los valores óptimos de adsorción de Cr(VI) son: pH de 3 unidades; tamaño de partícula menor que 0,074 mm; dosis de adsorbente de 5 g.dm-3 y tiempo contacto de 1 hora. A valores bajos de concentración del metal (1,0; 1,5 y 1,84 mg.dm-3) se obtuvo porcentaje de remoción superiores a 90, sin embargo a altos valores de concentración (2,5 y 3 mg.dm-3), se obtienen valores inferiores al 90 %. El proceso pudo ser estudiado a través de los modelos de Langmuir y de Freundlich, ya que el coeficiente de correlación para ambos modelos fue de 0,994 y 0,991 respectivamente. Se logra remover los iones Cr(VI) a valores de pH de 3 y 7 unidades en una matriz real, alcanzando valores de remoción de 96,85 % y 93,71 % respectivamente. Adsorption and/or formation of complexes of heavy metals based on the chemical activity of the biomass, it is the process known as biosorption and it is the base of a new technology for its removal in industrials effluent and its posterior recuperation. In this technology, different kinds of biomasses can be utilized such as: algae, microorganisms and agricultural subproducts. In this work, the adsorption of Cr(VI) was studied utilizing the nutshell of the fruit of the plant Cocos nucífera L as organic biomass. The optimal values of adsorption of Cr(VI) are: pH of 3 units, size of particle smaller than 0.074 mm, doses of adsorbent of 5 g.dm-3 and contact time of 1 hour. At low values of concentration of the metal (1.0, 1,5 and 1.84 mg.dm-3) percentage of removal superior to 90% were obtained, however, at high values of concentration (2.5 and 3 mg.dm-3) values inferior to 90 % are obtained. The process can be studied by the models of both, Langmuir and of Freundlich, because the , coefficient of correlation for these two models was 0.994 and 0.991 respectively. The ions Cr(VI) can be removed at values of 3 and 7 units in a real matrix, reaching removal values of 96.85% and 93.71% respectively.
