• #### Physical and real-time delineations on the electro-mechanical threshold ﻿

(1995)
As we increasingly encounter electronic communication and information systems in our everyday environment, we must recognize and critically respond to their impact on built architecture and on our physical and social bodies. ...
• #### Physical attractiveness biases in ratings of employment suitability: In search of the "beauty is beastly" effect ﻿

(2002)
The "beauty is beastly" effect, in which physically attractive females are held at a disadvantage in selection for male sex-typed jobs, is often cited in the physical attractiveness bias research, but has rarely ever been ...
• #### PHYSICAL CHARACTERIZATION AND HYDROISOMERIZATION ACTIVITY OF A PLATINUM-RHENIUM/PILLARED CLAY CATALYST ﻿

(1985)
Montmorillonite is a clay mineral which when exchanged with hydroxyaluminum oligomers produces a pillared clay mineral. On calcination at 500(DEGREES)C the pillars are fixed, and a microporous structure having good thermal ...
• #### Physical characterization of lithium niobate thin films on silicon substrates ﻿

(1988)
The structure and orientation of radio frequency sputtered lithium niobate (LiNbO$\sb3$) films on silicon substrates is determined using x-ray diffraction. The structure of the LiNbO$\sb3$ films is determined to be a strong ...
• #### Physical examination of binding parameters for tryptophan and oligomerization of tryptophan repressor and its site-specific mutants ﻿

(1988)
The interactions of Escherichia coli trp aporepressor and its ligands, tryptophan and trp operator DNA, were examined. To avoid the interference of fluorescence from the ligand, a hydrophobicity-dependent fluorophore, ...
• #### Physical Implementation of Synchronous Duty-Cycling MAC Protocols: Experiences and Evaluation ﻿

(2013-07-24)
Energy consumption and network latency are important issues in wireless sensor networks. The mechanism duty cycling is generally used in wireless sensor networks for avoiding energy consumption due to idle listening. Duty ...
• #### Physical layer algorithms with limited feedback: Power control and coding strategies ﻿

(2007)
The uncertainty in the received signal is the main limiting factor for the throughput of any communication system with limited resources. In this thesis we analyze the potential gain in throughput by managing channel ...
• #### PHYSICAL MAPPING OF THE ORIGINS OF REPLICATION OF BACILLUS SUBTILIS BACTERIOPHAGE SP01 ﻿

(1985)
The DNA of Bacillus subtilis bacteriophage SP01 is a linear duplex 140 kilobasepairs long, with direct terminal repeats of 12.4 kilobasepairs. It contains the unusual base 5-hydroxymethyluracil in place of thymine. Southern ...
• #### Physical Model of the Co-evolution of Bacteria and Viruses Mediated by CRISPR ﻿

(2016-07-12)
Bacteria and archaea have evolved an adaptive, heritable immune system that recognizes and protects against viruses or plasmids. This system, known as the CRISPR/Cas system, allows the host to recognize and incorporate ...
• #### PHYSICOCHEMICAL INTERACTIONS BETWEEN MONTMORILLONITE AND POLYMERIZING SYSTEMS: EFFECT ON PARTICLE-REINFORCED COMPOSITES (CONCRETE, ZERO-SHRINKAGE, EXPANDABLE) ﻿

(1986)
Highly filled polymer composites, such as polymer concrete (PC), suffer from setting stresses generated during the cure of the resin binder, when polymerization shrinkage is hindered by the close packing of filler and ...

(1969)
• #### Physiologically relevant reactions of myoglobin and hemoglobin with nitric oxide ﻿

(2006)
Recent clinical trials involving administration of a cell-free hemoglobin based blood substitute have shown that several detrimental side effects are the result of reactions with nitric oxide produced by endothelial cells. ...

(1979)

(1972)
• #### Piano performance and technique: A study of the modern grand piano ﻿

(2010)
The study of how the modern grand piano functions from a construction standpoint has been overlooked by modern pianists. This dissertation explores how an understanding of the inner workings of the piano will lead to more ...
• #### Piano Variations by Liszt, Lutoslawski, Brahms, and Rachmaninoff on a Theme by Paganini ﻿

(2012)
Theme and Variations is arguably one of the oldest musical forms in music history. Composers have used certain themes repeatedly as thematic sources for variations. Among them, Paganini's Caprice No. 24 in A minor is ...
• #### Picosecond Digital-to-Impulse (D2i) Radiators in Silicon ﻿

(2014-11-24)
Current techniques for terahertz (THz) time-domain spectroscopy (TDS) are based on femtosecond lasers and photoconductive antennas (PCAs). The PCA is the emitter and the detector of THz pulses and includes a THz antenna ...
• #### 'Pieces of experience literally seized': Arthur Dove's symbolic portraits in collage, 1924-1925 ﻿

(1988)
Arthur Garfield Dove's symbolic portrait collages are a unique body of work. They represent the multiplicity of artistic styles and thought in New York City during the first three decades of the twentieth century. As an ...
