Troodontidae is a clade of small-bodied theropod dinosaurs. A new troodontid, Gobivenator mongoliensis gen. et sp. nov., is described based on the most complete skeleton of a Late Cretaceous member of this clade presently known, from the Campanian Djadokhta Formation in the central Gobi Desert. G. mongoliensis is different from other troodontids in possessing a pointed anterior end of the fused parietal and a fossa on the surangular in front of the posterior surangular foramen. The skull was superbly preserved in the specimen and provides detailed information of the entire configuration of the palate in Troodontidae. Overall morphology of the palate in Gobivenator resembles those of dromaeosaurids and Archaeopteryx, showing an apparent trend of elongation of the pterygoid process of the palatine and reduction of the pterygopalatine suture toward the basal Avialae. The palatal configuration suggests that the skull of Gobivenator would have been akinetic but had already acquired prerequisites for later evolution of cranial kinesis in birds, such as the loss of the epipterygoid and reduction in contact areas among bones. © 2014 Springer-Verlag Berlin Heidelberg.

The activated carbon sheets made of cotton cloth were applied to the EDLC electrodes. The capacitance and internal resistance of the assembled EDLC cell in a beaker were measured. The density of capacitance was approximately 1F/cm2 in the EDLC electrode. The internal resistance was less than 1Ω in the EDLC cell. It was confirmed that the capacitance of active carbon sheet made of cotton cloth is in proportion to the area of active carbon sheet. From the obtained results, there is a possibility of the practical use of EDLC which is made of the carbonized and activated cotton cloth in low cost. © 2014 The Institute of Electrical Engineers of Japan.

The activated carbon particles made of charcoal were applied to the EDLC electrodes by using an alkaline activation method. The capacitance and internal resistance of the assembled EDLC cell were measured with 34% KOH water Electrolyte. The density of energy was approximately 2.6Wh/L in the EDLC cells. The internal resistance was less than 80mΩ in the EDLC cell. Outdoor LED lights were assembled by the charcoal EDLCs adding the solar panel, LED light and their control circuits to confirm the operations of its charcoal EDLC. From the obtained results, there is a possibility of the outdoor practical use of EDLC which is made of the activated charcoal particles in low cost. © 2015 The Institute of Electrical Engineers of Japan.
