In this study, spermatheca and eggs of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae were examined by light microscope SEM. The have ~1.30 mm length 0.94 width. Newly laid turn from white to yellow as soon embryonic differentiation. P. egg surface shows polygonal (usually hexagonal pentagonal) shapes. pipe shaped 6-7 micropylar projections. egg-burster which is a dark T-shaped or triangular p...

Begging is a complex display involving a variety of different visual and auditory signals. Parents are thought to use these signals to adjust their investment in food provisioning. The mechanisms that ensure the honesty of begging displays as indicators of need have been recently investigated. It has been shown that levels of corticosterone (Cort), the hormone released during the stress respons...

Bamboo oriented strand boards (BOSB) are very suitable for application in construction structures because of their excellent mechanical properties. This research investigated the shear performance bamboo I-beams composed BOSB to verify structural I-beams. Short beam tests and uniform vertical load capacity were performed investigate effects various factors on properties The results showed that ...

We appreciate the comments by Nezic et al. [1] regarding our article [2]. Nezic et al. pointed out the pinholes of the everting mattress sutures on the flange as the potential sites of bleeding. However, a recent Gelatin-sealed woven Dacron graft was considered because the problem was rare. In addition, we injected fibrin glue around the proximal suture line after sewing the Valsalva sinus skir...

A general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. The robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. The curvatures in pipeline are the most important constraints in front of the robot through navigation process. To study the adapt...
