Lithuanian University of Educational science is a university in Vilnius, Lithuania, which specializes in preparing school teachers and other educators. As of March 2013 it had approximately 8,500 students and 528 members of academic staff. Wikipedia.


The distribution of quantitative parameters of Lithuanian relief is analysed in different geomorphologic complexes: glacial edge, ground moraine, glaciofluvial, glaciolacustrine, aeolian, fluvial, littoral, erosion, karst and organogenic. Analysis of geodynamic processes taking place in the Lithuanian territory revealed quantitative distribution and intensity of these processes and a possible impact on relief transformation. The obtained results led to the following conclusions: erosion is the most intensive factor of Lithuanian relief transformation. It occurs in almost 50% of the Lithuanian area (32133 km2). The volume of all deposits re-deposited by erosion reaches 47.6 million m3 sediments per year. The thickness of denudation layer reaches up to 0.5 mm/year. Source

Investigation of a novel design tiny piezoelectric inertial motor is given in the paper. Operation principle of the motor is based on inertial motion of the slider applying sticks and slip phases between stator and slider. Piezoelectric motor has simple design and consists of the slider with a bimorph piezoceramic disc and the clamped cylindrical shaft used for sliding. The advantage of the motor design is the self-moving slider that obtains bidirectional inertial motion when the saw tooth or the pulse type excitation signal is applied at resonant frequency. Numerical investigation of the piezoelectric motor based on finite elements method was performed to analyse natural frequencies, modal shapes of the motor and slider response to the different excitation regimes. The influence of the Coulomb friction on the velocity of the slider is analysed. A prototype inertial piezoelectric motor was built, and measurements of electrical and mechanical characteristics were performed. The results of numerical and experimental study are discussed. © 2011 Elsevier Ltd. All rights reserved. Source

No Elachistinae have ever been recorded from Cameroon and only one species (Eretmograptis coniodoxa) was described by Meyrick in 1938 from the Democratic Republic of the Congo. Here, we present ten new species of the subfamily Elachistinae from Central Africa: Elachista cordata sp. n., Urodeta absidata sp. n., U. aculeata sp. n., U. crenata sp. n., U. cuspidis sp. n.U. faro sp. n., U. tortuosa sp. n. from Cameroon and U. acerba sp. n., U. bucera sp. n., U. talea sp. n. from the Democratic Republic of the Congo. The new species are diagnosed and illustrated with photographs of the adults and genitalia. Copyright © 2011 · Magnolia Press. Source

The taxonomic history of the genus Urodeta Stainton 1869 (Lepidoptera: Elachistidae: Elachistinae) is presented. Three new species: Urodeta acinacella Sruoga et De Prins, sp. nov., U. quadrifida Sruoga et De Prins, sp. nov. and U. trilobata Sruoga et De Prins, sp. nov., from South Africa are described. The new species are diagnosed and illustrated with photographs of the adults and genitalia. A global, annotated catalogue of the Urodeta species diversity is presented. The impact of formerly published taxonomic decisions on the position of Urodeta within Gelechioidea is discussed. Copyright © 2012 - Magnolia Press . Source

Basketball is one of the most popular sports games in the world. Professional basketball has become a significant contributor to global economics and business. Considerable funds attracted by the game motivate participants of the sporting process (players, coaches, club owners, administration and etc.) to strive for better athletic results, this way promoting internal and external rivalry. A large number of players and the desire of teams to attract better team members as well as improve the quality of the already available athletes, boost the use of assessment and rating processes. The most popular and widely used player rating systems are based on performance statistics, which reflect situational factors of the game. Most specialists believe that such systems lack objectivity. Meanwhile, the Authors suggest a systematic solution, i.e. an adjusted well-known TOPSIS method and principles for the design of the algorithm based on the method. As a consistent problem solving system, algorithms based on multi-criteria decision-making are regarded to be simple and clear, suitable to substantiate solutions as well as easily applied in practise. Methodologies used by the Authors will help ensuring a greater efficiency of player and team rating, more accurate prognoses of sports results, team formation, and optimisation of the training process considering individualism of team players and encouraging their versatility, i.e. conformity to general physical preparedness norms of the team. The suggested research methods could be used in other sports. Furthermore, these principles could be used in business management for team formation. © 2014 Elsevier Ltd. All rights reserved. Source
