A two cocycle is associated to any action of a Lie group on a symplectic manifold. This allows to enlarge the concept of anomaly in classical dynamical systems considered by F Toppan in [J. Nonlinear Math. Phys. 8, Nr. 3 (2001), 518­533] so as to encompass some extensions of Lie algebras related to noncanonical...

The publisher regrets that the volume number was wrongly allocated during the production process. The issue has been corrected with correct volume number (Current Volume Number - 659; Correct Volume Number - 222). The publisher would like to apologize for any inconvenience caused. DOI of original article:...

Emblic fruit wine rich in alcohol, phenolics. This experiment adopts the reverse high performance liquid chro-matography (HPLC) method for emblic leafflower fruit wine representative of phenolics gallic acid, quercetin content determination of study; And the emblic leafflower fruit forint phenol method...

The schedule control is a method which keep the tasks, resources and time balanced to achieve project's goal. And with the development of the construction,the time limit for a project control has become more important than ever before. The article uses Analytic Hierarchy Process (AHP) method to find...

This paper introduces the design of a radar plane position indicator (PPI) fast debugging equipment based on USB. Hardware platform is a high-speed 16 channel date acquisition card -USB4716,which is based on USB. Its internal actual is 8 parallel 16AD module. The sampling length and sampling frequency...

Portfolio has been used as summative assessment in many fields of study. Since 2010, clinical community medicine module has used portfolio to assess students. Nine portfolios were assigned to students within 5 weeks length module. This study aimed to identify the correlation of students' perspective...

Self-directed learning (SDL) emphasized the students to be responsible in their learning process. SDL capabilities need to be owned by physicians, so physicians will be able to face the continuous scientific changes and they can develop the lifelong learning capabilities. This study aimed to explore...

In this article, curve fitting is conducted on the original data of aluminum alloy via matlab. Then, to find out a fitting curve with optimal effect, comprehensive analysis is made on the judgement quantitative index of curve fitting. The wire feed rate of other given current is obtained with such fitting...

Please make the page settings of your word processor to A4 format (21 x 29,7 cm or 8 x 11 inches); with the margins:...

Blue fluorescent material combined with red uorescent dye doped into tris-(8-hydroxyquinoline) aluminum (Alq) in multilayer organic light-emitting diodes(OLEDs) were investigated. Basis device architecture is indium tin oxide (ITO)/ N,N -bis-(1-naphthyl)-N,N -diphenyl-1,1 -biph-enyl-4,4 -diamine(NPB...

In sewage treatment, the sewage whose carbon and nitrogen(C/N) ratios is less than 8 is defined as low C/N ratio sewage. This study contrasts the treatment effects under different C/N ratios in aerobic membrane bio-reactor. The experiment is performed in the following conditions: Temperature is from...

Alternative conception is students' conception of scientific concepts that are inconsistent with the conception of scientists. Various studies show that alternative conceptions of chemical concepts occur in students, including acid-base concepts. Various identification of alternative conception methods...

As millimeter wave (MMW) electronic technologies have matured, MMW receiver research is also in the rapid development which includes front-end and frequency synthesizer. They all needed isolation between RF and DC bias. The good design bias T which can realize high isolation between DC bias source port...
