Congenital malformations of the external and middle ear is the common reason of pediatric hearing impairment and cosmic problem. The treatment composes of auricular plastic surgery and auditory reconstruction surgery. The use of BAHA, vibrant sound-bridge and tissue engineering materials can significantly improve the treatment outcomes.

The paper presents cellular automata as a promising modeling approach to simulate the diffusion process as a 2D task. The proposed methodology is applied to the degradation assessment of civil engineering structures describing more realistically the spatial and temporal variability of harmful substance ingress (e.g. chloride ions in concrete). Some illustrative examples are presented together w...

We have shown the conversion of an amyloid fiber forming nucleation pathway of polyglutamine (polyGln) to a non-nucleated pathway, generating nanospherical amyloid particles. This is achieved by engineering an intermolecular salt bridge interaction between the positively charged lysine and the negatively charged glutamate residues, in two polyGln rich peptides. The mechanism of their formation ...

Asset developer decision-making is often neglected in energy systems models. We describe a new reverse-engineering method to bridge this gap, informing key policy and investment interventions needed achieve ambitious net-zero targets.

Bridge failures due to fires are more common than extreme weather or earthquakes. Yet, unlike wind and earthquake loading, fire does not receive the same level of attention. Major 21st Century incidents involving bridges listed discussed. Various methods by which could be considered in design reviewed Sources test data, include only one full scale to-date, provided. It is hoped that considering...

Abstract When determining the completion state of main cable a cableway bridge, although catenary theory can accurately consider nonlinear mechanical effect cable, iterative calculation is cumbersome and not convenient for engineering applications. Although based on parabola simple, accuracy long cables low. In this paper, considering avoiding calculation, fast algorithm wire rope bridge propos...

the national bridge stock of iran consists of about 330,000 bridges, of which around 50% are older than 30 years. since 2010, iran road maintenance & transportation organization has started implementing a comprehensive bridge management system in order to manage this aged stock efficiently. to predict future conditions of bridge stock, a heuristic numerical method is presented. this methodology...
