Couple relationship education at home: Does skill training enhance relationship assessment and feedback?

To evaluate the effective components of couple relationship education, 59 newlywed couples were randomly assigned to one of two couple relationship programs (CRE): (1) RELATE, which involved receiving feedback on their relationship based on the on-line RELATE assessment; or (2) RELATE + Couple CARE, which was RELATE plus completing the 6 unit Couple CARE relationship skill training program. Relative to RELATE, RELATE + Couple CARE produced more improvement in couple communication, and high relationship satisfaction across the next 12 months in women. Men sustained high and similar relationship satisfaction in either condition. Skill training CRE has additional benefits for couples beyond assessment and feedback.

MICROSCALE ENGINEERING APPLICATIONS IN BONE ADAPTATION

Advances in cell biology have been dramatic over the past two decades. One phenomenon now well established is that the mechanical loading of cells has a profound influence on their function. This phenomenon is particularly important for bones, because they alter their density and geometry in response to mechanical loading. In an attempt to understand and ultimately control the underlying biological mechanisms of this bone adaptation, researchers are now mechanically probing whole bones, bone cell cultures, and individual cells using a variety of microscale technologies. There is, however, a substantial need for improved technology. The overall goal of this review is to encourage the participation of the microscale engineering community in this new field of research. Specifically, we describe here possible clinical applications, introduce some basic concepts of bone and cell biology, describe the current microscale technology used in this field, and critically review experiment results. This should provide a basis for the entry of interested microscale engineers into this field.     

TWO-DIMENSIONAL SCHEME FOR CONVECTION-DIFFUSION WITH LINEAR PRODUCTION

In this article we consider the scalar transport governed by the convection-diffusion equation with linear production in two dimensions. The underlying idea in the development of a steady discretization scheme is to incorporate the analytical solution, obtained within a one-dimensional context, into the formulation. The method adopted here features exponential character in the weighted coefficients of the matrix equation, which generates a scheme with high accuracy. The analysis is followed by extending this discretization scheme to solve the convection-diffusion-production equation with a source term. In this article we present an analytical validation study of the method applied to two classes of model equations. Having verified that the method applies equally well for a transport scalar in either case with constant or variable flow velocity, we employ the one-dimensional scheme in the predictor and corrector steps to obtain the two-dimensional solution in an alternating direction-implicit fashion. The result obtained for the test considered in this article follows the trend of analytic data.     

Electrical characteristics of high dielectric constant BCTZ thin films

Abstract

High dielectric constant Ba_0.96Ca_0.04Ti_0.84Zr_0.16O₃ (BCTZ) thin films were deposited on Pt/Ti/SiO₂/Si substrates by spin on metal-organic decomposition (MOD) technique. Undoped and 0.4% Mg-doped BCTZ thin films were annealed in the temperature range from 600 to 900 °C for 1 hour in oxygen environment. The crystal structure of BCTZ thin films was analyzed by X-ray diffraction. The electrical properties of BCTZ thin films were investigated by capacitance—voltage (C—V) characteristics. Also, the electrical properties of these films were compared in conjunction with 0.4% Mg doping effect of BCTZ thin films for possible high dielectric constant material applications.
