8 9 A comparison was made between the composition of the recalcitrant organic matter (ROM) 10 isolated from a sandy forest soil as revealed by microwave assisted extractions and/or 11 hydrolyses and by usual pyrolysis techniques. Successive microwave irradiation treatments 12 were performed in H2O, 0.1 and 1 M HCl and 0.1 and 1 M KOH. At each step of the 13 treatment the insoluble residue was e...

Systems are an important part in today’s science education. Computer simulations have many advantages in teaching science systems. Our research goal is to test whether a hierarchical instructional scaffolding framework embedded in simulation-based learning environments and retrospective mental modeling task could facilitate mental model construction in learning science systems. This pilot study...

IN THE TITLE COUMARIN COMPOUND (SYSTEMATIC NAME: 6-butyryl-5-hy-droxy-8,8-dimethyl-4-phenyl-2H,8H-benzo[1,2-b;3,4-b']dipyran-2-one), C(24)H(22)O(5), also known as mammea A/AC cyclo D, the chromene and pyran rings are almost coplanar with a maximum deviation from the mean plane of 0.295 (2) Å. The attached phenyl group is inclined at 53.49 (8)° with respect to the chromene ring. The mol-ecular s...

Spatial scaffolding is a naturally occurring human teaching behavior, in which teachers use their bodies to spatially structure the learning environment to direct the attention of the learner. Robotic systems can take advantage of simple, highly reliable spatial scaffolding cues to learn from human teachers. We present an integrated robotic architecture that combines social attention and machin...

As a temporary facility, scaffolding has an essential role in providing work environment at height the construction industry. According to Occupational Safety and Health Administration (OSHA), approximately 65% of laborers on scaffolding. Scaffolding information needs be effectively managed with reliability provide safe environment. However, managing process remains challenging forgery risk man...

Axonal transport is required for the elaboration and maintenance of synaptic morphology and function [1, 2]. Liprins are scaffolding proteins [3] important for synapse structure and electrophysiology [4]. A reported interaction with Kinesin-3 (Kif1a) suggested Liprinmay also be involved in axonal transport [5]. Here, at the light and ultrastructural levels, we discover aberrant accumulations of...
