the cement gland (cg) is a transient organ, found in most anuran embryos and early larvae and located normally on the front of the head. its sticky secretion allows newly hatched larvae to attach to the egg jelly or to another support later and remain hidden and stationary until feeding starts. our ultrastructural studies showed that prominence structure of the cg in some species exists, but is...

The drilling is well known as one of the most common hole making processes in the industry.Due to close tolerance requirement for drilled holes in the most of work pieces, onlinecontrolling of the diameter of drilled holes seems to be necessary. In the current work, an onlinedimensional controlling system was developed for drilling process. Doing this, drilling processwas executed in different ...

Supramolecular fibers composed of monomers that self-assemble directionally via noncovalent interactions are ubiquitous in nature, and great interest chemistry. In these structures, the constitutive continuously exchange in-and-out assembly according to a well-defined supramolecular equilibrium. However, unraveling pathways their molecular determinants constitutes nontrivial challenge. Here, we...
