In this study, thin layers of titanium nitride (TiN) were deposited on H13 steel substrates at different duty cycles and temperature of 520 ˚C using plasma assisted chemical vapor deposition (PACVD). Uniaxial residual stress was calculated by X-ray diffraction (XRD) and Sin2 Ψ method. Then the residual stress of the samples were measured by Grazing Incidence X-ray Diffraction (GIXRD) method and...

Animals with anterior or posterior neocortical lesions as well as intact control animals were evaluated for changes in a-adrenergic sensitivity at five postoperative times. Colonic temperature decreases were measured in response to clonidine at each of the postoperative periods. The result indicated that a heightened heat-loss response was induced by clonidine that lasted 21 or more days after ...

There has recently been a great deal of interest in cognitive interventions, particularly when applied in older adults with the goal of slowing or reversing age-related cognitive decline. Although seldom directly investigated, one of the fundamental questions concerning interventions is whether the intervention alters the rate of cognitive change, or affects the level of certain cognitive measu...

This study examines 5 types of personality continuity--structural, mean-level, individual-level, differential, and ipsative--in a representative population (N=498) and a twin and sibling sample (N=548) of children and adolescents. Parents described their children on 2 successive occasions with a 36-month interval using the Hierarchical Personality Inventory for Children (I. Mervielde & F. De Fr...

Personality-relationship transactions were investigated in a general population sample of young German adults with three assessments over 8 years. Four general findings were obtained. First, personality development was characterized by substantive individual differences in change. Second, bivariate latent growth models indicated that individual differences in personality change were substantial...

OBJECTIVES We investigated how fluctuations and linear changes in health and cognitive resources influence the motivation to engage in complex cognitive activity and the extent to which motivation mediated the relationship between changing resources and cognitively demanding activities. METHOD Longitudinal data from 332 adults aged 20-85 years were examined. Motivation was assessed using a co...

The purpose of this factorial study was to establish normative data for the Italian version of the Communication Attitude Test (CAT) in order to determine whether or not the speech-associated attitude reported by Italian children who stutter (CWS) differs significantly from that of their nonstuttering peers (CWNS). Toward this end, the Italian CAT was administered to 149 CWS and 148 CWNS betwee...

The present study attempts to investigate the relationship between spatial configuration changes of Qom and the central core in the last half century. The main objective of this study is to review the Spatial form of Qom, and analyze the effect of changes in Urban configuration on the central core of the city and the main axes of urban activities during 1946 to 2011 and ultimately, Forecast the...
