The Department of Continuous Media and Structural Theory at the University Carlos III of Madrid (UC3M), in collaboration with the aeronautical companies EADS-CASA, EADS-SOCATA (France) and AERNNOVA, is executing several research projects involving the study of the behaviour of structural elements of planes that suffer an impact, a situation that planes might experience during their years of service.
As a result of this collaboration, experimental devices for the analysis of aeronautical components and numerical models are being developed, providing verification of the behavioural hypothesis for aeronautical structures of planes.
The research, which started in the year 2004 and still continues today, analyses problems that need to be evaluated for the certification of aircrafts, such as the question of impacts of external bodies against the airplanes during landing and take-off, comparable to the case that caused the accident of the Concorde on 25th July 2000.
On that occasion, the impact of an object against the wing of the supersonic plane during take-off caused a fire in the engine that led to the death of over a hundred passengers as well as ruining the impeccable record of the famous aircraft.
The risk of impact can also come from meteorological conditions, such as impacts of lumps of ice originating either from hail storms or the loose ice that sometimes accumulates on the plane itself. Ramón Zaera, Director of the Continuous Media and Structural Theory Department at the UC3M, states that the objective is both to develop an experimental study that reproduces the operative conditions of the aeronautical components as well as to produce numerical models that simulate the application of impulsive loads on the structures, the effect of changes of temperature and the damage caused to the components.
The developments in this field, are related to great aeronautical engineering challenges in Europe, so it is the case of the enormous Airbus A380 and the future generation of the A320, which were tested in a pioneering mechanical impact lab in Europe that was created by the UC3M and EADS-CASA for the execution of complex experimental procedures. Their pneumatic launchers, consisting of tubes about 4 meters in length, permit the reproduction of impacts and collisions on structural elements of the fuselage, wings, stabilizers or the gondola of aircrafts with speeds ranging from 300 km/h to 3,000 km/h. This lab, located on the Leganés campus of the university, has been researching projects summing up to 900,000 Euros since the year 2004.
The impact process on aeronautical structures takes place in a very short period of time, in the range of a few milliseconds, which makes data acquisition harder in experimental tests and necessitates the consideration of inertial effects and non-linear behaviours when using mechanical models of materials. This is why it is necessary to use numerical simulations of the experiments using specific models.
The Department Continuous Media and Structural Theory at the UC3M contributes to the technological advance in the aeronautical sector through the participation of many of their professors in two research groups, Dynamics and Fracture of Structural Elements and Advanced Mechanical Elements. In this aspect, this department presents a respected research trajectory, having published 20 scientific articles during the year 2008 in journals with a high JRC rating in their category, such as those related with the experimental and/or numerical analysis of structural elements under dynamic loads and impacts.
Since the year 2008, the department participates as an Organismo Público de Investigación (OPI) of AERNNOVA in a CENIT project entitled "Innovación en Composites Avanzados y Rear-End Optimizado" lead by AIRBUS and with a total cost of 34 million Euros. It’s attached to the INGENIO 2010 program and is a reflection of the dedication of public organism and the industrial sector for university level research in aeronautical safety.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
