INTER-TRACHEID AND CROSS-FIELD PITTING IN COMPRESSION AND OPPOSITE WOOD OF

Inter-tracheid and cross-filed pit pairs in compression and opposite wood of Norway spruce (Picea abies) were examined.The size, appearance, and frequency of bordered pits on the radial side of axial tracheids and their aperture specification were studied.The type, Psyllium size, and number of half-bordered pits between the axial tracheids and rays

Our research aimed to investigate the effectiveness of auditory, visual, Psyllium and audiovisual warning signals for capturing the attention of the pilot, and how stimulus onset asynchronies (SOA) in audiovisual stimuli affect pilots perceiving the bimodal warning signals under different perceptual load conditions.In experiment 1 of the low percep
