Additive manufacturing (AM) has been highly popular in recent years and the number of scientific efforts on this useful way increased day by day. Up to now, majority studies accumulated physical mechanical properties three-dimensional (3D) printed specimens. In paper, impact additively manufactured polylactic acid (PLA) parts were addressed detail. All specimens fused deposition modeling (FDM)....
Notch signaling regulates many fundamental events including lateral inhibition and boundary formation to generate very reproducible patterns in developing tissues. Its targets include genes of the bHLH hairy and Enhancer of split [E(spl)] family, which contribute to many of these developmental decisions. One member of this family in Drosophila, deadpan (dpn), was originally found to have functi...
Fillers can be employed as reinforcement in the design of automobile crash boxes to improve its performance in terms of energy absorption, expected crushing fashion and initial peak force magnitude. The current research focuses on the investigation of crashworthiness of the high-strength steel (HSS) columns filled with reinforced aluminium honeycomb fillers. The crashworthiness of HSS steel cra...
The infant larynx differs from that of the adult in more ways than size alone . Its position in the neck is more cephalad than in the adult. The thyroid notch positioned high, posterior to the hyoid bone, the bone obscuring the thyroid notch as a landmark for tracheotomy. The epiglottis has an omega shape and may be somewhat tubular . The cuneiform cartilages, arytenoids, and posterior supraglo...
Objective(s): NOTCH signaling pathway is well known for its role in cell fate, cell survival, cell differentiation, and apoptosis. Some of the NOTCH signaling genes are critical for endometrial function and implantation in animals and appear to play a similar role in humans. The purpose of the current study was to investigate the potential roles of some main components of the NOTCH family in hu...
The distal region of the Drosophila leg, the tarsus, is divided into five segments (ta I-V) and terminates in the pretarsus, which is characterized by a pair of claws. Several homeobox genes are expressed in distinct regions of the tarsus, including aristaless (al) and lim1 in the pretarsus, Bar (B) in ta IV and V, and apterous (ap) in ta IV. This pattern is governed by regulatory interactions ...
The Charpy energy of the sample after heat–treatment was significantly higher than the as–welded sample when the V–notches were located 1 or 3 mm away from FL. However, when the V–notch was located on FL, the improvement in toughness from the heat treatment was not so obvious with no enhancement noted for the test temperature of −40 ◦C. Under this condition, the facets of the fracture surface a...
