A research team of the Public University of Navarre (Basque Country), under the supervision of professors Jesus Zurita Gabasa and Jesus Mª Pintor Borobia, from the department of Mechanical, Energetic and Materials Engineering, is working in a project to improve and optimise vibrating tables that are used in the agri-foodstuffs sector. The project is being done by the request of the company Tecnologia Alimentaria Urtasun from Navarre (Basque Country) , manufacturer of this kind of machinery.
The company Tecnologia Alimentaria Urtasun focuses its activity in the design, production, commissioning and control of the whole production lines for the food industry. That includes the production line of vibrating tables. These tables are the machinery used to transport fruits and vegetables. They are called vibrating tables, because they actually function by vibration, so that the product moves with small jumps through the table, so that it reduces the damage. That way, by operators located at both sides of the table or in a totally mechanised way, the damaged parts can be removed or the product can be selected or distributed.
The main problems of these tables are related to their vibrating character. These machines must vibrate, and the more they vibrate the better it is, because the product moves faster forward and they can transport higher amounts of load. However, that causes greater deformations, and as a consequence, there can be problems of rupture or fatigue due to the presence of oscillating loads. And that causes a damage, which is accumulated in the material.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
