• #### EXPERIMENTAL DISENGAGEMENT OF MORPHOGENETIC PROCESSES AND ITS EFFECTS ON PRIMORDIAL GERM CELL COLONIZATION OF THE GONADAL RIDGES IN RANA PIPIENS ﻿

(1986)
During normal embryogenesis in Rana pipiens the primordial germ cells (PGCs) undergo a displacement from deep within the ventral endoderm of the Stage 17 tailbud embryo to the dorsal endodermal crest of the hatched Stage ...
• #### Experimental evaluation of explicit and symbolic automata-theoretic algorithms ﻿

(2006)
The automata-theoretic approach to the problem of program verification requires efficient minimization and complementation of nondeterministic finite automata. This work presents a direct empirical comparison of well-known ...
• #### Experimental evolution of TetX2: Correlating changes in fitness to their structural and functional origins ﻿

(2012)
The study of protein evolution and adaptation resides at the junction between the disciplines of biological chemistry and evolutionary biology. We chose the B. thetaiotaomicron tetracycline resistant enzyme TetX2, as our ...
• #### Experimental Free Energy Landscape Reconstruction of DNA Unstacking Using Crooks Fluctuation Theorem ﻿

(2013-06-05)
Nonequilibrium work theorems, such as the Jarzynski equality and the Crooks fluctuation theorem, allow one to use nonequilibrium measurements to determine equilibrium free energies. For example, it has been demonstrated ...
• #### Experimental investigation and constitutive modeling of marine clay ﻿

(1993)
A new cross-anisotropic elasto-plastic constitutive model is developed based on experimental observations of marine clay from the Gulf of Mexico. Standard triaxial and torsional simple shear tests performed on the ...
• #### Experimental investigation for constitutive modeling of fine sand under cyclic loading using hollow cylinder specimens ﻿

(1991)
An experimental program for the understanding of the behavior of fine cohesionless soil under monotonic and cyclic loading and for the development and refinement of constitutive models has been undertaken. An experimental ...

(1978)
• #### Experimental investigation of crust-mantle hybridization in the Earth’s shallow upper mantle ﻿

(2014-11-13)
Chemical heterogeneities in the Earth’s mantle, such as subducted sediments and oceanic crust, along with volatiles such as H2O and CO2 affect melting processes, hence, chemical differentiation of the Earth and their ...
• #### Experimental observation of the photon structure function at 21 GeV ﻿

(1998)
The triggered photon structure function at center-of-mass energy 21 GeV is measured from the interaction $\gamma$p $\to$ jets. Descriptions of the experimental apparatuses are given and the physics goals of the experiment ...
• #### Experimental results and three-dimensional simulations of instabilities in a rotating lid-driven cylinder ﻿

(2012)
An experimental setup for a rotating lid-driven cylinder problem is designed and constructed in the context of modeling bulk semiconductor crystal growth techniques. Details concerning construction of the experimental setup ...
• #### Experimental setup for the operation of gas electron multipliers in liquid-gas xenon detectors ﻿

(2004)
A setup for the realization of dual-phase experiments using xenon as the active medium in a radiation detector has been built. The setup consists of a gas purification system capable of achieving a purity of the gas in the ...
• #### EXPERIMENTAL SIMULATION OF THERMAL MATURATION IN SEDIMENTARY ORGANIC MATTER. (VOLUMES I AND II) ﻿

(1981)
This study simulates thermal maturation of liptinitic and humic organic matter (Phosphoria shale and Rattlesnake Butte lignite) by isothermal pyrolysis at temperatures of 230(DEGREES), 275(DEGREES) and 325(DEGREES)C for ...
• #### Experimental studies of nucleate pool boiling from artificial active sites ﻿

(1963)
Artificial active sites were studied during nucleate pool boiling of degassed carbon tetrachloride. The pressure of the system was controlled a t one and also at one and one-half atmospheres. Dynamic two phase behavior ...

(1969)
• #### Experimental studies of the fractional quantum Hall effect and the Wigner solids ﻿

(2010)
This Ph.D. thesis is composed of two parts: the first part is concerned with electron transport in the higher Landau levels (LL) in a two-dimensional electron system (2DES); the second part is focused on the Wigner Crystal ...
• #### Experimental study of (He_,d) and (He_,t) reactions on Be_ and B__ ﻿

(1966)
The reactions Be9(He3,d)B110, Be9(He3, t)B9, B11(He3d )C12, and B11(He3, t )C11 were studied using a doubly ionized 10 MeV He3 beam. Particles were detected in a Delta E, E solid state counter telescope. The Delta E and E ...
• #### Experimental study of heat transfer to hypersonic nozzle walls ﻿

(1963)
The heat transfer rate from a high enthalpy gas to the walls of a diverging nozzle, through which the gas was flowing, has been experimentally determined. The experimental results are compared with the predictions of several ...

(1978)
• #### Experimental Study of Potassium and Strontium Rydberg Atoms - Chaotic Ionization, Quantum Optical Phenomena and Multiphoton Excitation ﻿

(2014-04-24)
Very-high-n (n~300) Rydberg atoms serve as a powerful tool to study chaos and quantum optical phenomena. Measurements using a series of alternating impulsive kicks applied to potassium Rydberg atoms reveal that a phase ...
