The conservation status of birds in the Ketambe Research Station area, Gunung Leuser National Park, needs to be done so that more attention can paid preservation bird diversity. This study aims observe various three altitude zones, namely zone 1 (350-550 m asl), 2 (550-800 and 3 (800-1050 asl). Observations were made May-August 2019 at Station, Southeast Aceh. results observations as a whole, t...

Growth rates of seedlings of eight tropical rain forest tree species were compared under five different canopy openness levels (FU and 50, 200, 800, 3200 m gaps). RGR exhibited a positive relation with canopy openness with species attaining their highest RGR at the 800 m (4 species) or 3200 m (3 species) gaps. Seed mass and RGR were negatively related. The increase in RGR between small and larg...

In a recent study competitive road cyclists experienced substantial gains in sprint and endurance performance when sessions of high-intensity interval training were added to their usual training in the competitive phase of a season. The current study reports the effect of this type of training on performance of 20 distance runners randomized to an experimental or control group for 5 to 7 weeks ...

Deformationsbewegungen gedeutet, obwohl nicht auszuschließen ist, daß auch CC-Valenzschwingungen beteiligt sind. Darüber hinaus darf nicht außer Acht bleiben, daß selbst durch Schwingungskopplung eine kontinuierliche Änderung des Charakters einer Frequenz mit variierender Halogensubstitution erwartet werden kann. Die Infrarotspektren fast aller Pentaerythrithalogenide sind durch zwei starke Ban...
