A fabrication stress model for axisymmetric filament wound composite structures
A comprehensive fabrication stress model was developed to compute fiber stresses in axisymmetric filament wound composite structures at any stage of the fabrication process, a prerequisite for the evaluation of the performance of the composite structures from fabrication process variables. The …

The racial and ethnic discrimination stress model: development, adaptation, and preliminary empirical testing
… 2019) with connections to mental health (i.e., distress, anxiety, and depression; Carden et al., 2021; Hart et al., 2021; Thomas Tobin & Moody, 2021). For decades, researchers have consistently demonstrated the utility of family stress models to examine stressor-related outcomes; however, only …

Understanding Family Routines in a Head Start Sample: A Family Stress Model Perspective
<p>According to the family stress model (FSM), economic pressure, or the perceived strain of economic hardship, contributes to parent mental health problems, which impacts parenting behaviors and, in turn, results in negative child outcomes like child externalizing behavior. Studies have shown that …

A Role for Microglia Activation in Modulating Behavior in a Variable Stress Model for Depression
… more than 300 million people worldwide. Stress, being a potent trigger for various mood disorders, including depression, affects both the peripheral and central immune systems. Microglia are the resident immune cells in the brain and changes in their morphology and state of activation in …

A DIATHESIS-STRESS MODEL OF VICTIMIZATION: RELATIONS AMONG TEMPERAMENT, PEER VICTIMIZATION, PSYCHOPATHOLOGY, AND HEALTH PROBLEMS
… University Carbondale. TITLE: A DIATHESIS-STRESS MODEL OF VICTIMIZATION: RELATIONS AMONG TEMPERAMENT, PEER VICTIMIZATION, PSYCHOPATHOLOGY AND HEALTH PROBLEMS MAJOR PROFESSOR: Dr. Lisabeth F. DiLalla, Ph.D. Youth who are victimized by their peers are more likely to develop symptoms of …

Anxious Solitude and Peer Exclusion: Evidence for a Diathesis-Stress Model of Internalizing Trajectories in Childhood
A diathesis-stress model is proposed in which the joint forces of personal vulnerability (anxious solitude) and interpersonal adversity (peer exclusion) predict depressive symptoms in children over time. Children's (N = 388; 50% female) social behavior, peer relations, and emotional adjustment were …

Implementation of 3DPTV for turbulence analysis and subgrid-scale stress model testing of a backward-facing step flow
… field with many new applications and models being introduced on a regular basis. The active nature of this field establishes the need for high-resolution, 3-dimensional experimental data for assessment and development of Subgrid-Scale (SGS) Models. An experimental technique well-suited …

Parameter establishment and verification of a fabrication stress model and a thermo-kinetic cure model for filament wound structures
… when coupled together have the capability to model the filament winding and curing processes for composite structures. The "Filament Winding Cure" (FWCURE) code is a thermo-kinetic model. FWCURE models the resin viscosity, percent of cure, temperature, resin flow, and layer location. As these …

A hybrid finite element procedure for soil-structure interaction including construction sequences
… displacement finite element method, the hybrid stress model, is applied to problems in geomechanics. A two-dimensional finite element procedure based on the hybrid stress model is developed for simulation of construction sequences including underground and surface excavations. In this procedure, …

Finite element modeling of the filament winding process using ABAQUS
A comprehensive stress model of the filament winding fabrication process, previously implemented in the finite element program, WACSAFE, was implemented using the ABAQUS finite element software package. This new implementation, referred to as the ABWACSAFE procedure, consists of the ABAQUS software …

Modelling of the filament-winding fabrication process
A stress model of the filament-winding fabrication process, previously implemented in a finite element program, was improved. Pre- and post-processing codes were developed to make the program easier and more efficient to use. A program which is used to design filament wound composite rocket motor …

THE LONG-TERM COURSE OF BIPOLAR SPECTRUM DISORDER: APPLICATIONS OF THE BEHAVIORAL APPROACH SYSTEM (BAS) MODEL
… of the Behavioral Approach System (BAS) model as applied to the course of bipolar spectrum disorders. In this model, when a vulnerable individual experiences a BAS activation-relevant event, the weak regulatory strength of the BAS interacts with pre-event BAS state and is likely to lead …

The assessment of psychological vulnerability in adolescents: An alternative to genetic high-risk methodology
… designed within the framework of the diathesis-stress model of psychopathology which assumes that manifest psychopathology is the result of the interaction of stress with a latent vulnerability. Previous research has relied on a genetic risk criterion, selecting as subjects the offspring of …

Fluid-Structure Interaction of Large Viscoelastic Vessels Under Pulsatile Conditions
… of the vessel wall through a novel, dynamic model developed from a force analysis of a compliant vessel under two-dimensional (2D) stress. First, the instantaneous elasticity of a purely elastic, synthetic vessel with known properties was extracted using the 2D stress model and compared to …

Numerical Investigation of Cleavage Fracture in Welded Connections of Steel Moment Resistant Frames
"This study applies an advanced micro-mechanics model of cleavage fracture in ferritic steels to examine the behavior of welded, moment resistant steel frames of the type widely constructed prior to the 1994 Northridge earthquake. The Weibull stress model for cleavage, coupled with 3-D analyses of …

Stress reactivity, stress appraisal and coping responses in schizophrenia
… the etiology of schizophrenia. According to the stress-vulnerability model, the experience of stress is critical to the onset and/or maintenance of schizophrenia. Although there is no conclusive evidence to suggest that people with schizophrenia experience more stressful events than the general …

A granular flow model of an annular shear cell
… that allow minerals to be extracted are best modelled using granular flows. A single rheological description that captures all the features of granular flows has not yet been realised, although considerable progress towards a complete theory has been made. Existing models of such horizontally …

Auditor Stress: Antecedents and Relationships to Audit Quality
… investigated RAQP failed to examine RAQP from a stress model perspective which incorporates stressors, stress measures and stress consequences into the model and to measure the interactions among these constructs. Previous research has mainly focused on the direct effect of stressors (e.g., time …
