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 ...
Chemostratigraphic and lithostratigraphic signatures of the Anthropocene in estuarine areas from the eastern Cantabrian coast (N. Spain)
(Elsevier, 2015-04)
A range of chemostratigraphic and lithostratigraphic markers of human impacts can be recorded in four estuaries located in the eastern Cantabrian coast (northern Spain). Metal-enriched levels and stable Pb isotopic ratios ...
Attachment to parents and aggressiveness in adopted adolescents: a multi-sample comparison study
(Wiley, 2018-10-31)
This study examined adopted adolescents’ levels of attachment security to parents and aggressiveness as compared to those of community nonadopted adolescents and of clinical nonadopted adolescents. Three different subsamples ...
Electric arc furnace slag and its use in hydraulic concrete
(Elsevier, 2015-08-15)
Electric arc furnace oxidizing slag (EAFS) is a by-product of the steelmaking industry, generated after the melting and the preliminary acid refining of liquid steel. It is a stony material that is easy to crush for use ...
Fast driving between arbitrary states of a quantum particle by trap deformation
(2016-12-22)
By performing a slow adiabatic change between two traps of a quantum particle, it is possible to transform an eigenstate of the original trap into the corresponding eigenstate of the final trap. If no level crossings are ...
Assessing the potential of the recycled plastic slow pyrolysis for the production of streams attractive for refineries
(Elsevier, 2019-07-25)
The slow pyrolysis of recycled high-density polyethylene (HDPE) has been investigated in a batch autoclave reactor at 430–490 °C and reaction times of 15–60 min, with the aim of obtaining the maximum yield of plastic oil ...
Effect of CdSe nanoparticle addition on nanostructuring of PS-b-P4VP copolymer via solvent vapour exposure
(Elsevier, 2013-10-28)
The surface morphology of poly(styrene-b-4 vinyl pyridine) (PS-b-P4VP) diblock copolymer thin films
after solvent vapor annealing has been studied. Morphological features can be switched upon exposure
to vapors of a ...
Flexible polyurethane foams based on 100% renewably sourced polyols
(Elsevier, 2014-10-5)
Since polyol is one of the major components in polyurethane foam synthesis, introducing renewably
sourced polyols in the foam formulation leads to materials with high renewable carbon content. A series of
flexible ...
Effect of different hemicelluloses characteristics on film forming properties
(Elsevier, 2013)
Hemicelluloses are known to have good gas barrier properties makes them of interest to film applications.
Corn cob, cotton waste, olive, apple tree pruning, pepper and chilli wastes were used as hemicelluloses
sources ...
Does a non-circular chainring improve performance in the bicycle motocross cycling start sprint?
(Department of Sports Medicine, Medical Faculty of Uludag University, 2014)
Maximising power output during the initial acceleration phase of a bicycle motocross (BMX) race increases the chance to lead the group for the rest of the race. The purpose of this study was to investigate the effect of ...
