Particle Bubble Interactions in Flotation Systems
(2007-05-15)
Flotation separation is an important process in mineral processing and paper recycling. Flotation is a separation process used to remove particles from a liquid stream. Bubbles are introduced into the liquid stream, and, ...
Particle Charge Determination in a Magnetized Dusty Plasma Flow
(2023-05-04)
Dusty plasmas consist of components typically found in a plasma (electrons, ions
and neutral particles) as well as micrometer sized dust particles. The structural and dynamic
properties of a dusty plasma system are ...
Particle Motion Analysis in Pancreatic Islets Isolation using a Quadrupole Magnetic Flow Sorter
(2010-12-14)
Pancreatic islet transplantation offers a viable option to achieve permanent metabolic control in Type 1 diabetes patients. However, large quantities of pure viable donor islet cells are necessary for transplantation. Using ...
Particle Simulation of Lower Hybrid Waves and Electron-Ion Hybrid Instability
(2014-05-01)
Lower hybrid wave (LHW) has been of great interest to laboratory plasma physics for decades due to its important applications in particles heating and current drive in plasmas devices. There are two fundamental characteristics ...
Particle Size Affects Physical and Chemical Properties of 100% Pine Bark Horticultural Substrate
(2017-04-21)
Pine bark is the most commonly used substrate component for container plant production in the southeastern United States, with some growers using 100% pine bark. Substrate physical and chemical properties directly affect ...
Particle Swarm Optimization Applied to the Design of a Nonlinear Control
(2006-05-15)
A method of searching for a tuning of an input to state linearizing controller is
presented. The problem of ?nding the appropriate weights of the control law’s terms
is treated as an optimization problem. Given the highly ...
Partnering With Physicians: How Are Medical Speech-Language Pathologists Perceived
(2010-01-05)
The purpose of this research was to gather insight regarding physicians’ understanding and view of the medical speech-language pathologist. Some questions were compared to previous data presented in a prior survey by ...
Partnering with Reach Out and Read Alabama to Understand Families’ Experiences with Books and Their Babies: The Reading and Relationships Project
(2022-07-22)
Shared book reading is associated with higher quality parent-child interactions (Canfield et al., 2020a), as well as child cognitive (e.g., Baker, 2013; Baker et al., 2017) and socioemotional development (Downer & Mendez, ...
Party Polarization: Congressional Divergence on Environmental Policy from 1970-2008
(2012-04-17)
We investigate empirically the importance of a conjectured linkage between economic conditions and increasing party divergence with respect to national-level environmental policy in the United States. Using data from ...
Passage and Fine Scale Movements of Paddlefish and Smallmouth Buffalo near Claiborne Lock and Dam
(2019-07-10)
Dams often impede spawning migrations of fishes, concentrating adults in their tailwaters. Little is known about behavior of migrating fishes as they approach dams, including where fish are located in the tailrace, their ...
Passive Chemiresistor Sensor Based on Iron (II) Phthalocyanine Thin Films for Monitoring of Nitrogen Dioxide
(2010-12-09)
Nitrogen dioxide gas is a common atmospheric pollutant that is hazardous to human health at concentrations as low as one part per million (ppm). Iron (II) phthalocyanine (FePc) thin films have been identified to be sensitive ...
Passive microfluidic methods for sampling hormone secretions from primary islets and adipocytes
(2013-07-11)
We have developed an 8-channel passive microfluidic device that is capable of sampling both primary islet and adipocytes. Although there are microdevices already published in the literature; they require bulky external ...
Passive Pendulum Balancer for Rotor Systems
(2006-05-15)
Automatic, passive self-balancing systems are important tools for reducing the effects of synchronous vibration in a variety of rotating machinery. Such systems are ideally capable of precise balancing, subject to certain ...
Paternal Role Development and Acquisition in Fathers of Preterm Infants: A Qualitative Study
(2005-08-15)
Fathers of preterm infants are under-represented in the literature on parents of preterm infants. The acquisition and development of the paternal role of fathers of preterm infants while their singleton child was hospitalized ...
Path and Cycle Decompositions
(2008-08-15)
A $G$-design is a partition of edge set of K_v in which each element induces a copy of G. The existence of G-designs with the additional property that they contain no proper subsystems has been
previously settled when G ...
Path Curvature on a Convex Roof
(2007-12-15)
Given a set of rectangles, R1 through Rk, where Ri and Ri+1 share a common
edge and these common edges are congruent and parallel to each other. The resulting
”roof” is part of the surface of a convex body. We’ll consider ...
Path Decompositions of the Kneser Graph
(2013-04-22)
Necessary and sufficient conditions are given for the existence of a graph decomposition of the Kneser Graph $KG_{n,2}$ into paths of length three and four, and of the Generalized Kneser Graph $GKG_{n,3,1}$ into paths of ...
Path Delay Tuning for Performance Gain in the face of Random Manufacturing Variations
(2011-04-18)
Moore's laws predictions of transistor densities doubling every two years in an integrated circuit has held true for the past fifty years, and is predicted to hold true in the coming few years. But as technologies shrink ...
Path Duplication Using GPS Carrier Based Relative Position for Automated Ground Vehicle Convoys
(2010-04-15)
A GPS based automated convoy strategy to duplicate the path of a lead vehicle is presented in this dissertation. Laser scanners and cameras are not used; all information available comes from GPS or inertial systems. An ...
