The effect of strontium incorporation into sol-gel biomaterials on their protein adsorption and cell interactions
(Elsevier, 2019-02-01)
It is known strontium can both inhibit the osteoclast formation and stimulate the osteoblast maturation, so biomaterials containing this element can favour bone structure stabilisation. The addition of Sr to biomaterials ...
Looking for Energy Losses of a Rotary Permanent Magnet Magnetic Refrigerator to Optimize Its Performances
(MDPI, 2019-11-19)
: In this paper, an extensive study on the energy losses of a magnetic refrigerator prototype
developed at University of Salerno, named ‘8MAG’, is carried out with the aim to improve the
performance of such a system. The ...
Admittance study of grid-connected VSCs for harmonic oscillatory instabilities
(IET, 2019-07)
Voltage source converters (VSCs) can reduce damping of grid-connected VSC systems at harmonic resonances, leading to system instability. The conductance of the VSC admittance can be shaped selecting appropriate VSC parameter ...
Arquitecturas interactivas. Prácticas visuales emergentes en la ciudad interfaz
(Universidad Politécnica de Valencia, 2019)
We are living the transition from
a static to a dynamic architecture
driven by the integration of new
technologies into the urban
environment. In this scenario,
citizens abandon their passive
roles in order to ...
Complement proteins regulating macrophage polarisation on biomaterials
(Elsevier, 2019-09-01)
One of the events occurring when a biomaterial is implanted in an host is the protein deposition onto its surface, which might regulate cell responses. When a biomaterial displays a compromised biocompatibility, distinct ...
Influence of operational modes of the internal heat exchanger in an experimental installation using R-450A and R-513A as replacement alternatives for R-134a
(Elsevier, 2019-12-15)
This paper presents a first and second law of thermodynamics study using experimental data from a medium capacity refrigeration system using R-450A, R-513A and R-134a as working fluids and an internal heat exchanger (IHX) ...
Enhancing Freehand Sketching in Industrial Design: Description and Implementation of a Drawing Methodology for More Effective Representations
(Common Ground Research Networks, 2019)
Freehand sketching is an important part of the design process that allows one to communicate in a quick and gestural way the first ideas about new concepts and is a medium for graphic thinking. It is important for architects ...
Tuning PID controllers with Symmetric Send-on-Delta sampling strategy
(Elsevier, 2019-10-23)
A procedure for tuning PID controllers with SSOD sampling for FOPTD systems is proposed. It is based on the definition of a new robustness measure to avoid limit cycle oscillations, called the Tsypkin margin (MT). This ...
Synthesis and characterization of silica-chitosan hybrid materials as antibacterial coatings for titanium implants
(Elsevier, 2019-01)
To avoid dental implant-related infections and to promote the osseointegration of titanium implants, the application of silicon and chitosan containing coatings is proposed. Silicon is a well-known osteogenic element and ...
Energy Rehabilitation of Social Housing in Vulnerable Areas Case study: a 1950s Building in a Medium-sized Mediterranean City
(Ierek Press, 2019-03)
In the urban context, buildings play a key role as they are energy consumers. In well-established cities with a
high percentage of aged building stock, the focus should lie on sensitive urban areas where the weakest ...
