Process variables controlling consistency of carbon nanotube forest growth
… to better understand and control for the observd process variations. An exploratory investigation of growth parameters allowed for a local optimization of growth temperature and hydrocarbon flow rates, as well as an acceptable range of sample placement in the CVD furnace to achieve ~1mm tall CNT …

Effects of filtration process variables on filter cake properties and formation
Drilling mud is fundamental during the drilling process because it performs multiple tasks which make the perforation of the rock possible. For this reason, lost circulation, the loss of drilling mud through fractures in the formation, represents a serious issue in the oil and gas industry, since …

Effects of Fused Filament Fabrication Process Variables on Microstructural Alignment and Intra-layer Properties in PLLA
Extrusion-based 3D printing is commonly used to produce complex structures from thermoplastics. Conventional fused filament fabrication (FFF) is used widely and forms objects through layer-by-layer deposition. However, there is often a need for thin support structures based on single print layers, …

Effect of various process variables on the mechanical properties of laminates produced through resin transfer molding process
… interest in the Resin Transfer Molding Process (RTM) evolved from its potential for reducing manufacturing costs, while increasing the capability of manufacturing complex parts. This manufacturing process like many other processes involves a large number of variables, consisting of both …

An Examination of the Relationship Between Process Variables and Outcome Indicators in the Therapeutic Use of Play With Children
Lastly, the study makes several contributions to future research in the area of children's affect measurement including improving on the already developed Emotional Discomfort Scale (Howe and Silvern (1981)). These improvements as well as the manner in which phase of treatment and level of …

Evaluation of effect of extrusion process variables on mechanical properties of extruded collagen tubes and effect of post extrusion treatments
This study evaluated the effect of extrusion process variable on mechanical properties of extruded collagen tubes made using a specialized extruder, made by ZOKO Corporation of Czechoslovakia. Three extrusion variables were considered; extrusion speed, linear draw rate and rotation speed. Using …

Gas assisted injection moulding: Experiment and simulation. Industrial machine experimental studies of the effect of process variables on gas bubble formation, and with simulation based upon a pseudo-concentration method.
The gas assisted injection moulding process is an important extension to conventional injection moulding. Gas assist can be applied in a number of ways, but here the penetration of a gas bubble through the polymer melt is of interest. A 3D fi nite element implementation of a pseudo concentration …

Computer Control of Fermentation With a Vision-Based Sensing System
… implemented. The system consisted of a central process controller, a bench scale fermentor system, a computer-controlled automatic sampling system and a computer vision sensing system. A fermentor controller, part of the fermentor system, maintained the process variables during the fermentation …

Cognitive correlates of worry in adolescents
… worry in adults. This model proposes that four process variables are associated with excessive worry: intolerance of uncertainty, positive beliefs about worry, negative problem orientation, and cognitive avoidance. The goal of the present study is to explore the relationship between worry and …

Psychotherapy Using Distance Technology: A Comparison of Face -to -Face, Video, and Audio Treatments
… experimental scrutiny by comparing selected process variables across three modes of psychotherapy: face-to-face, real-time video conference, and two-way audio (analogous to telephone). The process variables were chosen to represent the working alliance between the therapist and the client, a …

A Meta-Ethnography of International Case Studies on Contributors to School Success
… the indirect influence of leadership and which process variables are most effective in achieving school and student success. Moreover, we know very little about what that indirect influence looks like in various school and cultural contexts (e.g., how the influence processes differ across school …

Implementation of a Brief Preventative Couples Intervention in a Primary Care Setting
… within-person and between-person variance in process variables and outcome measures. Seventy-eight (N = 78) couples were randomized to the 4-week MH protocol (n = 41) or control condition (n = 37). Results demonstrated men in the intervention group exhibited 1) greater improvements in …

The Effect of Traumatic Brain Injury on Exposure Therapy in Veterans with Combat-related Posttraumatic Stress Disorder
… of this study was to compare exposure therapy process variables in veterans with PTSD only and veterans with PTSD+TBI. Results suggest that individuals with PTSD+TBI engage successfully in exposure therapy, and do so no differently than individuals with PTSD only. Additional analyses indicated …
