The torque converter into the automatic drivetrain has been quite important as well as the hydraulic clutches due to the capacity of amplifying the torque highly accurate over 98% of low RPM, working as attachment of 1:1in high RPM, to get a better efficiency and low gas intake for saving the environment. Because of its desing and fuction, the torque converter engages and disengages automatically the power of the engine to the gear, focusing on the engine RPM. With the powertrain on, at an idling speed, the power is weak due to the lack of fluid flow; However when speeding up, the powertrain gets stronger through the torque converter job. This research aims on the torque converter features based on the main variables. The first one was a test on the dynamometer for finding the torque and power curve, and the second one, an intake test. This study was made at CCICEV in order to understand how the torque converter works in automatic vehicles.

Published: April 2019

The authors developed economic and statistical analysis on bilateral economic and trade and investment partnership between the Republic of Kyrgyzstan and the Russian Federation for the past decade and formulated proposals for the further coordination of long-term foreign economic policy.The paper provides an analytical review of intercountry trade and investment cooperation with emphasis on manufacturing. It is based on data from various international organizations (United Nations Conference on Trade and Development, Eurasian Economic Commission) and the National statistical committee of the Kyrgyz Republic. Extensive statistical material supports the thesis on using the benefits of integration for the economy of the Kyrgyz Republic, even though it remains dependent on political fluctuations and has an underdeveloped business environment.The authors examine the implementation of bilateral contracts, projects and agreements from 2008 to 2016, with an emphasis on critical long-term interests of two states, and discuss perspectives for trade and economic cooperation in the medium and long terms. They also cover questions regarding coordination of economic policy in the abovementioned areas. Considerable attention is given to evidence-based reasoning in favor of strengthening the Russian-Kyrgyz partnership in the field of trade and investment. There is also a need for statistical support for the implementation of joint programs to improve the sustainability and competitiveness of national economies, as well as a broad integration cooperation agenda within the Eurasian Economic Union and other associations.
Behaviour of Fe, Mn and Mg during the differentiation of granites and W-Sn bearing hydrothermal activity in the Vila Real area (Northern Portugal)
Authors: Garcia Daniel 
Published: April 2019

Les granites à deux micas hercyniens de la région de Vila Real (Nord Portugal) montrent une évolution chimique simple dans laquelle les rapports Mn/Fe et Fe/Mg croissent dans les roches et dans leurs micas. Mg est fortement fractionné en faveur de la muscovite relativement à Fe et Mn (Fe/Mg biotite : Fe/Mg muscovite varie entre 2,2 et 2,7). Cette distribution entraîne une gamme de variation du rapport Fe/Mg plus étendue dans les micas granitiques que dans les roches correspondantes et les micas des granites différenciés apparaissent en fort contraste chimique avec ceux des autres granites et ceux des roches métamorphiques environnantes.
Ce contraste est mis à profit pour discuter le rôle de l'encaissant dans le chimisme des minéralisations en W, Sn et des produits de l'altération hydrothermale associée. Mn est systématiquement apporté et Fe déplacé dans les greisens : les compositions observées sont compatibles avec l'établissement d'équilibres d'échange impliquant Fe, Mn et Mg entre roches et solutions. Le rapport Fe/Mg des muscovites hydrothermales reflète le chimisme du milieu hôte ; au contraire, leur rapport Mn/Fe s'établit à une valeur définie dans certains greisens et semble y traduire l'influence d'une source granitique différenciée.
