In this paper, we addressed the flow patterns over a light boxplane scale model to explain previously discovered disagreement between its predicted and experimental aerodynamic characteristics. By tuft CFD visualization, explored causes yielding large zero lift pitching moment coefficient, lateral divergence, difference in fore aft elevator lift, poor high performance of aircraft. The investiga...

Recent research has explored the relationships between family and cultural issues, claiming attention on the need to consider and evaluate cultural values and beliefs as useful factors to promote positive family adjustment and parenting outcomes (Cardoso and Thompson, 2010; Taylor et al., 2012). This paper explored self-perception of parental role, family maladjustment and cultural beliefs in a...

The challenge feminist scholarship posed to family studies has been largely met through the incorporation of research on gender dynamics within families and intersectional differences among them. Despite growing attention to gender as performance and power in more diverse families, the more difficult work of understanding the dynamics of change among institutions including the family and using ...

A biometrical genetical analysis of IgG, IgM, and IgA levels in 134 sets of twins is reported. High heritabilities, around .8, are found for all three immunoglobulin levels, and possible reasons for lower heritabilities found in family studies are discussed. There is evidence for genetical dominance tending to decrease IgM and IgA levels, but there is no evidence for the importance of family en...

This paper presents a performance evaluation of two passive cooling strategies, daytime ventilation and night cooling, for a generic, six-story suburban apartment building in Beijing and Shanghai. The investigation uses a coupled, transient simulation approach to model heat transfer and airflow in the apartments. Wind driven ventilation is simulated using computational fluid dynamics (CFD). Occ...

OBJECTIVE Several components of event-related potentials--P50 suppression, P300 amplitude and latency, and mismatch negativity--have been proposed as potential endophenotypes for schizophrenia on the basis of family studies. The present study used a twin design to estimate the extent of genetic overlap between these indices and the liability to schizophrenia. METHOD The authors measured misma...

prevention efforts [1]. In this sample of Greenland Inuit where both HIV and undernutrition remain uncommon, the risk of developing TB was markedly higher in persons with co-existing diabetes than in persons without. The very high risk associated with diabetes suggests potential reduction in the Greenland TB incidence rates through incorporating diabetes control and prevention in TB prevention ...

This paper presents the CFD modeling methodology and validation for steady-state, normal operation in a PWR fuel assembly. This work is part of a program that is developing a CFD methodology for modeling and predicting single-phase and two-phase flow conditions downstream of structural grids that have mixing devices. The purpose of the mixing devices (mixing vanes in this case) is to increase t...

A parallel CFD code capable of simulating flow within moving boundaries is coupled to a beam element structural dynamics code. The coupled codes are used to simulate fluid-structure interaction for a class of applications involving long and slender structures, e.g., suspension bridges and offshore risers. Due to the difference in size and dimensionality of the 3D CFD problem on one side, and th...
