Context. Within the framework of the accepted simplifying hypotheses, an approximate scheme of calculation of the parameters of the active and passive sections of the trajectory is proposed, which allow to study the trajectory properties of the existing a... see more

In external ballistics of a conventional spin-stabilised artillery projectile, there are a numberof trajectory models developed for computing trajectory elements having varying degrees ofcomplexity. The present study attempts to propose a single mathemati... see more

Thousands of tons of metal-containing sludge are produced every month at machine-building, especially bearing producing and metallurgy enterprises where is processed. In the production of bearings, up to 10.0 thousand tons of sludge containing up to ... see more

Programa Educativo para la Producción Intelectual de los docentes de la Escuela Latinoamericana de Medicina/Educational Program for the Intellectual Production of the teachers of the Latin American School of Medicine Programa Educativo para la Producción Intelectual de los docentes de la Escuela Latinoamericana de Medicina/Educational Program for the Intellectual Production of the teachers of the Latin American School of MedicineObjetivo: diseñar un Programa Educativo para la producción intelectual de los docentes de la Escuela Latinoamericana de Medicina que se corresponda con las exigencias de la Educación Médica en la sociedad contemporánea.Materiales y métodos: el universo lo conformaron 302 docentes fijos que laboran en la Escuela Latinoamericana de Medicina. Se seleccionó una muestra de 100 docentes, lo que representa el 34 % de la población. Se utilizaron como métodos teóricos el análisis documental y la modelación. Como métodos empíricos encuestas y la prueba de desempeño, valorando la significación del cambio en el comportamiento de los indicadores en la misma a través de la utilización de la prueba no paramétrica de Mac Nemar.Resultados: la aplicación del Programa Educativo influyó en el desempeño profesional de los docentes, logrando que la categoría excelente, muy buen desempeño y buen desempeño aumentaran comparativamente con los resultados de la prueba de entrada, en cuanto a las de regular y mal desempeño disminuyeron, esta última en mayor cuantía.Conclusiones: la Educación Avanzada como teoría que tributa a las Ciencias Pedagógicas, contribuye a la solidez científica del Programa Educativo. Los resultados obtenidos en la práctica pedagógica y en las indagaciones teóricas y empíricas realizadas, permitieron considerar que el Programa Educativo propicia el desarrollo de la producción intelectual de los docentes de la Escuela Latinoamericana de Medicina.ABSTRACTObjetive: to design an Educational Program for the intellectual production of teachers of the Latin American School of Medicine that corresponds to the demands of Medical Education in contemporary society.Materials and methods: the universe consisted of 302 permanent teachers who work at the Latin American School of Medicine. A sample of 100 teachers was selected, representing 34% of the population.The documentary analysis and the modeling were used as theoretical methods. As empirical survey methods and the performance test, assessing the significance of the change in the behavior of the indicators in it through the use of the non-parametric test of Mac Nemar.Results: the application of the Educational Program influenced the professional performance of the teachers, achieving that the excellent category, very good performance and good performance increased comparatively withthe results of the entrance test, in terms of the regular and poor performance decreased, the latter in greaterquantity.Conclusions: Advanced Education as a theory that pays tribute to Pedagogical Sciences, contributes to the scientificstrength of the Educational Program. The results obtained in the pedagogical practice and in the theoretical andempirical investigations carried out, allowed to consider that the Educational Program promotes the development ofthe intellectual production of the teachers of the Latin American School of Medicine.

Theoretical bases of structural modelling the electrolit processes of a covering by iron are offered.

The PI3K/Akt/mTOR pathway plays an essential role in a wide range of biological functions, including metabolism, macromolecular synthesis, cell growth, proliferation and survival. Its versatility, however, makes it a conspicuous target of many pathogens; ... see more

This paper presents the construction, mathematical modeling and testing of a scaled universal hydraulic Power Take-Off (PTO) device for Wave Energy Converters (WECs). A specific prototype and test bench were designed and built to carry out the tests. The ... see more

Context. There were considered the issues of improving the accuracy and reliability of  automatic vessel motion control systems in conditions of large deviations in sensors measurements during maneuvering and failures of sensors and actuators. The ob... see more

Context. Poor iron ore which requires enrichment are the raw material basis for the steel industry. Their grinding in the early stages dueto cost overruns electricity, steel balls and the lining reduces the competitiveness of products. Reduce the cost ove... see more
