The Maipo River as a biogeographical barrier to Liolaemus monticola (Tropiduridae) in the mountain ranges of central Chile
(1997)
Univariate and multivariate statistical analyses of 39 meristic characters recorded for 12 samples of the lizard Liolaemus monticola were used to compare geographical variation in morphology with chromosomal races north ...
The Aconcagua River as another barrier to Liolaemus monticola (Sauria: Iguanidae) chromosomal races of central Chile
(Sociedad de Biología de Chile, 2003)
The Aconcagua River as another barrier to Liolaemus monticola (Sauria: Iguanidae) chromosomal races of central Chile
(Sociedad de Biologia de Chile, 2003)
Univariate and multivariate statistical analyses of 28 meristic characters recorded for 19 samples of the lizard Liolaemus monticola monticola were used to compare geographical variation in morphology with chromosomal races ...
Effect of the type of clay organo-modifier on the morphology, thermal/ mechanical/ impact/barrier properties and biodegradation in soil of polycaprolactone/clay nanocomposites
(John Wiley & Sons Inc, 2012-08-23)
The effect of addition of unmodified (CNaþ) and modified (C30B and C20A) montmorillonites on the performance of polycaprolactone (PCL) based nanocomposites prepared by melt intercalation was studied. The study covers ...
Concordance of morphological variation and chromosomal races in Liolaemus monticola (Tropiduridae) separated by riverine barriers in the Andes
(1992)
Intra‐ and interpopulation morphological variation in 14 meristic characters was assessed in twelve previously karyotyped population samples of Liolaemus monticola monticola, representing two chromosomal races: the Southern ...
Study of polypropylene surface modification by air dielectric barrier discharge operated at two different frequencies
(2012-10-18)
In this work, air dielectric barrier discharge (DBD) operating at the line frequency (60 Hz) or at frequency of 17 kHz was used to improve the wetting properties of polypropylene (PP). The changes in the surface hydrophilicity ...

Acetylene plasma polymer treated by atmospheric dielectric barrier discharge
(Elsevier B.V., 2014-09-01)
Plasma polymer films are very attractive for industrial applications in several sectors such as in the electronic, mechanic, biomedic, coating and others, due to its good adhesion, being insoluble in mild acids and bases ...
An Evaluation of the Dielectric Barrier Discharge Treatment on the Mechanical, Structural and Morphological Properties of Carbon Fibers
(Inst Aeronautica & Espaco-iae, 2018-01-01)
Carbon fibers (CFs) have been widely applied in the manufacture of polymeric composites. The mechanical properties of these composites depend on the adhesion in the matrix/CF interface. Since the CFs have poor adhesion ...
