Fast quasiadiabatic dynamics
(2015-10-07)
We work out the theory and applications of a fast quasiadiabatic approach to speed up slow adiabatic manipulations of quantum systems by driving a control parameter as near to the adiabatic limit as possible over the entire ...
Comparison between experimental values and standards on natural stone masonry mechanical properties
(Elsevier, 2012-03-01)
[EN] The research presented in this paper investigates the mechanical properties under compressive loads of a natural stone masonry. Selected materials and arrangement are typical from the Romanesque period, the main ...
Design and implementation of a droop control in d-q frame for islanded microgrids
(The Institution of Engineering and Technology, 2013-09-01)
The droop control method is usually selected when several distributed generators (DGs) are connected in parallel forming an islanded microgrid. This is because of the advantages it offers such as flexibility, absence of ...
Effect of the sampling rate on the assessment of flicker severity due to phase jumps
(IEEE, 2011)
This paper presents an analysis of the effect of the sampling rate on the calculation by a digital flickermeter of the flicker severity caused by phase jumps. The new edition of the IEC 61000-4-15 standard includes an ...
Effect of different organosolv treatments on the structure and properties of olive tree pruning lignin
(Elsevier, 2014-05-25)
Different organosolv processes (acetosolv, formosolv and acetosolv/formosolv) were applied to extract lignin from olive tree pruning. Obtained lignins were characterized by several methods to determine their composition, ...
Duplicate and Circulating Frames Discard Methods for PRP and HSR (IEC62439-3)
(IEEE, 2013-11)
Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR), defined in the IEC62439-3 about high availability automation networks and proposed as reference network topologies for substation communication ...
Efficacy of management policies on protection and recovery of natural ecosystems in the Urdaibai Biosphere Reserve
(Natural Areas Association, 2011-10-01)
Knowledge of landscape patterns and dynamics is essential for land use planners and natural resources managers. They need to know how landscapes have changed in order to determine the consequences and efficacy of the ...

Effects of a putative antidepressant with a rapid onset of action in defeated mice with different coping strategies
(Elsevier, 2012-04-22)
There is evidence suggesting that stressful social events may result in depressive-like disorders, but the development of these disorders depend on the way in which people cope with stress. Although antidepressants are ...
Combining Small-Vertebrate, Marine and Stable-Isotope Data to Reconstruct Past Environments
(Nature, 2015)
Three very different records are combined here to reconstruct the evolution of environments in
the Cantabrian Region during the Upper Pleistocene, covering ~35.000 years. Two of these records
come from Antoliñako Koba ...
