In vertebrates, face and throat structures, such as jaw, hyoid and thyroid cartilages develop from a rostrocaudal metameric series of pharyngeal arches, colonized by cranial neural crest cells (NCCs). Colinear Hox gene expression patterns underlie arch spe ...
New correlations predicting the local boiling heat transfer coefficients for vertical flow over a tube bundle have been developed. These correlations were developed for three different classes of tubes: smooth, low-finned, and Turbo-BII HP. These correlati ...
The pharyngeal arches give rise to multiple organs critical for diverse processes, including the thymus, thyroid and parathyroids. Several molecular regulators of thymus and thyroid organogenesis are strikingly conserved between mammals and zebrafish. Howe ...
Over the past few years, several genes involved in the development of the tetrapod limbs have been isolated and characterized. Thus, it becomes possible to study some of the developmental mechanisms responsible for the morphogenesis of these complex struct ...
In nature, many small animals use jumping locomotion to move in rough terrain. Compared to other modes of ground locomotion, jumping allows an animal to overcome obstacles that are relatively large compared to its size. In this thesis we outline the main d ...
Pelvic motion is of great importance when walking, and have thus to be taken into account while developing rehabilitation robotics. This paper describes the implementation of a pelvic motion amplitude prediction model on a pelvic orthosis and tests on vali ...
Among the different negative cavitation effects that are associated with the cavitation presence (efficiency drop, noise and vibrations etc.), cavitation erosion is still one of the main limiting features in the modern trend towards designing hydraulic mac ...
The presence of two sets of paired appendages is one of the defining features of jawed vertebrates. We are interested in identifying genetic systems that could have been responsible for the origin of the first set of such appendages, for their subsequent d ...
Modern jawed vertebrates possess two sets of paired appendages. The specific molecular genetic events associated with their origin remain enigmatic. Recently we suggested that certain T-box genes, transcription factors playing essential roles in vertebrate ...
Strategies for hybrid locomotion such as jumping and gliding are used in nature by many different animals for traveling over rough terrain. This combination of locomotion modes also allows small robots to overcome relatively large obstacles at a minimal en ...
