Performance evaluation is one of the most important issues in the field of parallel kinematic manipulators (PKMs).As a very important class of PKMs, the redundant PKMs have been studied intensively.However, the performance evaluation of this type of PKMs is still unresolved and a challenging endeavor.In this paper, indices that assimilate motion/fo
Course a pied - Enfant - Chaussures - Trail The chiral title compound, C19H32O2, contains a [4.3.0]-bicyclic moiety in which the shared C—C bond presents a trans configuration and a side chain in which the C=C double bond shows an E conformation.The conformations of five- and six-membered rings are envelope (with the bridgehead atom bearing t
Nucleic acid sensor elements are proving increasingly useful in biotechnology and biomedical applications.A number of ligand-sensing, conformational-switching ribozymes (also known as allosteric ribozymes or aptazymes) have been generated by some combination of directed evolution or rational design.Such sensor elements typically fuse a molecular re
This paper results from discussions triggered during the "Stream Ecology Symposium" that took place at the XIII Congress of the Brazilian Society of Limnology in September of 2011 in Vape Battery Natal, Brazil.Based on our experiences, we have raised several questions regarding ecological studies of headwater streams facing threats under global-cha
In the work of traditional education management, the efficiency of education management is affected by the lack of comprehensive understanding of the connotation of information management, the weak foundation of information construction and the unsound management system.To this end, we should 5 correctly understand the value of education management
