and multiferroic [ 2 ] materials. For instance, ferroelectric materials at morphotropic phase boundaries (MPB), where multiple structural phases with ferroelectric polarizations pointing in different crystallographic directions coexist, often display large piezoelectric coeffi cients. [ 3– 5 ] It is the ferroelectric distortions, which accompany the polarization rotation that leads to enhanceme...

This paper proposes a panel unit root test for micropanels with short time dimension (T ) and large cross section (N). There are several distinctive features of this test. First, the test is based on a panel AR(1) model, which allows for cross-sectional dependency, which is introduced by the initial condition’s assumption of a factor structure. Second, the test employs the panel AR(1) model wit...

A discriminant method was proposed for modeling and quantifying the consistency of regulatory mechanisms in cardiovascular system (CVS) apparently healthy volunteers those suffering from circulatory disorders associated with cervical spine osteochondrosis (OCS) somatoform autonomic dysfunction (SAD). The congruence parameters ECG intervalometry (DCI) pulse wave duration (PWD) according to volun...

Th e purpose of the present study was to investigate the reliability and validity of the Turkish version of the Tromso Social Intelligence Scale (TSIS) developed by Silvera, Martinussen, and Dahl (2001). 719 students from Sakarya University participated in the study. Construct validity and criterion related validity and reliability were assessed. Factor analysis for Turkish university students ...

In this paper we consider estimation and inference of common breaks in panel data models via adaptive group fused lasso. We consider two approaches — penalized least squares (PLS) for firstdifferenced models without endogenous regressors, and penalized GMM (PGMM) for first-differenced models with endogeneity. We show that with probability tending to one both methods can correctly determine the ...

Calving is a key event on any cattle farm, with both economic and animal welfare consequences when complications arise. Although mostly reported in highly selected breeds, problematic calving performance is also a worry to the unselected dualpurpose Murboden breed, local to Austria. Th is study presents genetic parameter estimates for calving ease and stillbirth in Murboden cattle. Furthermore,...

Electrochemical characteristic parameters such as diffusional permeability, ion transport number, fi xed charge concentration and electrical resistance for a regenerated cellulose/polypropylene-supported membrane (RC/PP sample) in contact with NaCl solutions at different concentrations were determined. The effect of the polypropylene support on mass and charge transport was estimated by compari...

Richards, Lundqvist-Korf and Hossfeld growth functions were fi tted to age-height data of European chestnut (Castanea sativa Mill.) dominant trees on the northern slopes of Belasitsa mountain, Southwest Bulgaria. Th e model prediction performance was evaluated using quantitative as well as qualitative examinations. Goodness of fi t of each model was estimated by the coeffi cient of determinatio...

For 120 specimens and fi gures of Fragilariforma, 10 Legendre coeffi cients were calculated as shape descriptors. For each half valve apically bisected, 50 x,y coordinates were used to calculate Legendre coeffi cients. Principal components analysis (PCA) was used to ordinate the shape descriptors as a total shape gradient of valve forms. The fi rst four principal components explained 90.3 % of ...

The paper presents new non-ionic deep eutectic solvent (DES) composed of natural and non-toxic components i.e. guaiacol, camphor levulinic acid in 1:1:3 molar ratio as a promising absorbent for removal of selected volatile organic compounds (VOCs) including dichloromethane, toluene, hexamethyldisiloxane and propionaldehyde from model biogas. The affi nity DES VOCs was determined vapour-liquid c...
