Crystallization is the most serious bottleneck in high-throughput protein-structure determination by diffraction methods. We have used data mining of the large-scale experimental results of the Northeast Structural Genomics Consortium and experimental folding studies to characterize the biophysical properties that control protein crystallization. This analysis leads to the conclusion that crystallization propensity depends primarily on the prevalence of well-ordered surface epitopes capable of mediating interprotein interactions and is not strongly influenced by overall thermodynamic stability. We identify specific sequence features that correlate with crystallization propensity and that can be used to estimate the crystallization probability of a given construct. Analyses of …
Evaluation Of Silica Monoliths In Affinity Microcolumns For High-Throughput Analysis Of Drug–Protein Interactions, Michelle J. Yoo, David S. Hage
Evaluation Of Silica Monoliths In Affinity Microcolumns For High-Throughput Analysis Of Drug–Protein Interactions, Michelle J. Yoo, David S. Hage
David Hage Publications
Silica monoliths in affinity microcolumns were tested for the high-throughput analysis of drug–protein interactions. HSA was used as a model protein for this work, while carbamazepine and R-warfarin were used as model analytes. A comparison of HSA silica monoliths of various lengths indicated columns as short as 1 to 3 mm could be used to provide reproducible estimates of retention factors or plate heights. Benefits of using smaller columns for this work included the lower retention times and lower back pressures that could be obtained versus traditional HPLC affinity columns, as well as the smaller amount of protein that …

David Sellmyer Publications
Rapidly solidified Ni54Fe27−2xGa19+2x (x=0, 1, 2, 3, and 4) ferromagnetic shape memory alloys were made by melt-spinning with variation of Fe and Ga contents to report on the martensitic phase transformation, microstructures, and magnetic properties. Rapid solidification produced pure L21 phase by preventing the formation of γ-phase. To study the effect of heat treatment on the phase transitions, microstructures, and the magnetic properties, the melt-spun ribbons were partly heat treated at different temperatures of 800, 900, 1000, 1100, and 1200 K with holding times of 5, 10, and 15 min followed by either water …

To sustain waterfowl populations at levels of the 1970s, as prescribed by the North American Waterfowl Management Plan (1986), private landowners must continue to provide habitat for wetland wildlife. Private landowners oversee the majority of wetlands remaining in the United States, so their cooperation is essential to any major conservation effort to restore and sustain waterfowl populations in the Mississippi Flyway. Many groups have worked together since the 1980s to develop waterfowl habitat on private lands.Much progress has been made, and this publication helps guide continuing efforts. This publication is for private landowners in the Lower Mississippi Flyway who want …
The Efficacy Of Ovocontrol® P (Nicarbazin) As A Contraceptive For Pigeons In Urban Ipm, Alexander Macdonald, Erick Wolfe
The Efficacy Of Ovocontrol® P (Nicarbazin) As A Contraceptive For Pigeons In Urban Ipm, Alexander Macdonald, Erick Wolfe
Other Publications in Wildlife Management
Pigeons are found in virtually all urban and developed areas of the United States. They are considered a pest species and provided no protection under federal or state laws that safeguard other birds. Pigeons cause extensive property damage and are a source of public health risk and disease.
Pigeons are commonly poisoned with non-selective toxicants. OvoControl (brand of nicarbazin) provides a non-toxic and humane alternative -- contraception or “birth control” for birds. Developed in collaboration with the USDA National Wildlife Research Center in Fort Collins, CO and Experiment Station in Gainesville, FL, OvoControl P for pigeons was registered by EPA …

Spin Quantum Dynamics In Molecular Magnets, John Henderson
Spin Quantum Dynamics In Molecular Magnets, John Henderson
Electronic Theses and Dissertations
Molecular magnets are ideal systems to probe the realm that borders quantum and classical physics, as well as to study decoherence phenomena in nanoscale systems. The control of the quantum behavior of these materials and their structural characteristics requires synthesis of new complexes with desirable properties which will allow probing of the fundamental aspects of nanoscale physics and quantum information processing. Of particular interest among the magnetic molecular materials are single-molecule magnets (SMMs) and antiferromagnetic (AFM) molecular wheels in which the spin state of the molecule is known to behave quantum mechanically at low temperatures. In previous experiments the dynamics …
The Validity Of Animal Experiments In Medical Research, Gill Langley
The Validity Of Animal Experiments In Medical Research, Gill Langley
Experimentation Collection
Other animals, such as mice, rats, rabbits, dogs and monkeys, are widely used as surrogates for humans in fundamental medical research. This involves creating disorders in animals by chemical, surgical or genetic means, with the aim of mimicking selected aspects of human illnesses.
It is a truism that any model or surrogate is not identical to the target being modelled. So, in medical research, experiments using animals or cell cultures or even healthy volunteers instead of patients (being the target population with the target illness) will inevitably have limitations, although these will be greater or lesser depending on the model.

The Minimization Of Research Animal Distress And Pain: Conclusions And Recommendations, Kathleen Conlee, Martin Stephens, Andrew N. Rowan
Laboratory Experiments Collection
While the attention given to preventing, assessing, and alleviating pain in research animals has increased noticeably in recent decades, much remains to be done both in terms of implementing best practices and conducting studies to answer outstanding questions. In contrast, the attention to distress (particularly non-pain induced distress) has shown no comparable increase. There are many reasons for this discrepancy, including the conceptual untidiness of the distress concept, the paucity of pharmacological treatments for distress, and perceived lack of regulatory emphasis on distress. These are challenges that need to be addressed and overcome. This book is intended to help meet …
Green Chemistry Using Bismuth Compounds: Bismuth(Iii) Triflate Catalyzed Allylation Of Cyclic Acetals, Matthew J. Spafford, '09
Green Chemistry Using Bismuth Compounds: Bismuth(Iii) Triflate Catalyzed Allylation Of Cyclic Acetals, Matthew J. Spafford, '09
Honors Projects
Cyclic acetals (dioxolanes, dioxanes, and dithianes) are common protecting groups in organic synthesis but they can also be converted to other useful functional groups. A bismuth(III) triflate-catalyzed multi component reaction involving the allylation of cyclic acetals followed by in situ derivatization with acid anhydrides to generate highly functionalized esters and thioesters has been developed under solvent-free conditions. Most reagents used to date for the allylation of cyclic acetals are highly corrosive or toxic and are often required in stoichiometric amounts. In contrast, the use of a relatively non-toxic and non-corrosive bismuth(III) based catalyst makes this methodology benign and attractive.
On The Application Of Locality To Network Intrusion Detection: Working-Set Analysis Of Real And Synthetic Network Server Traffic, Robert Lee
Electronic Theses and Dissertations
Keeping computer networks safe from attack requires ever-increasing vigilance. Our work on applying locality to network intrusion detection is presented in this dissertation. Network servers that allow connections from both the internal network and the Internet are vulnerable to attack from all sides. Analysis of the behavior of incoming connections for properties of locality can be used to create a normal profile for such network servers. Intrusions can then be detected due to their abnormal behavior. Data was collected from a typical network server both under normal conditions and under specific attacks. Experiments show that connections to the server do …

Detection Of Steganography-Producing Software Artifacts On Crime-Related Seized Computers, Asawaree Kulkarni, James Goldman, Brad Nabholz, William Eyre
Journal of Digital Forensics, Security and Law
Steganography is the art and science of hiding information within information so that an observer does not know that communication is taking place. Bad actors passing information using steganography are of concern to the national security establishment and law enforcement. An attempt was made to determine if steganography was being used by criminals to communicate information. Web crawling technology was used and images were downloaded from Web sites that were considered as likely candidates for containing information hidden using steganographic techniques. A detection tool was used to analyze these images. The research failed to demonstrate that steganography was prevalent on …

Prevention Is Better Than Prosecution: Deepening The Defence Against Cyber Crime, Jacqueline Fick
Prevention Is Better Than Prosecution: Deepening The Defence Against Cyber Crime, Jacqueline Fick
Journal of Digital Forensics, Security and Law
In the paper the author proposes that effectively and efficiently addressing cyber crime requires a shift in paradigm. For businesses and government departments alike the focus should be on prevention, rather than the prosecution of cyber criminals. The Defence in Depth strategy poses a practical solution for achieving Information Assurance in today’s highly networked environments. In a world where “absolute security” is an unachievable goal, the concept of Information Assurance poses significant benefits to securing one of an organization’s most valuable assets: Information. It will be argued that the approach of achieving Information Assurance within an organisation, coupled with the …

Isolation And Analysis Of Cyanobacterial Dna, Tiffany Crosby
Isolation And Analysis Of Cyanobacterial Dna, Tiffany Crosby
Senior Honors Theses and Projects
Cyanobacteria are a phylum of bacteria that possess a diverse number of biological characteristics. One of the evolutionary innovations of the cyanobacteria are its ability to perform oxygenating photosynthesis, which all cyanobacteria are able to perform. It is believed that a form of metabolism became the dominant method for producting fixed carbon from carbon dioxide (CO2) at around 3.5 billion years ago. Instead of using hydrogen sulfide, whose generated waste products were difficult to eliminate, the photosynthetic cyanobacteria used water as their hydrogen source (1). Many cyanobacteria are also capable of fixing atmospheric nitrogen (2). Cyanobacteria are present …

Network Utility Maximization (NUM) techniques, which cast resource sharing problems as one of distributed utility maximization, have been investigated for a variety of optimization problems in wireless and wired networks. Our recent work has extended the NUM framework to consider the case of resource sharing by multiple competing missions in a military-centric wireless sensor network (WSN) environment. Our enhanced NUM-based protocols provide rapid and dynamic mission-based adaptation of tactical wireless networks to support the transport of sensor data streams with very small control overhead. In particular, we focus specifically on mechanisms that capture the joint nature of mission utilities and …

Integrated Resource Allocation And Scheduling In Bidirectional Flow Shop With Multi-Machine And Cos Constraints, Hoong Chuin Lau, Zhengyi Zhao, Shuzhi Sam Ge
Research Collection School Of Computing and Information Systems
An integer programming (IP) model is proposed for integrated resource allocation and operation scheduling for a multiple job-agents system. Each agent handles a specific job-list in a bidirectional flowshop. For the individual agent scheduling problem, a formulation is proposed in continuous time domain and compared with an IP formulation in discrete time domain. Of particular interest is the formulation of the machine utilization function-- both in continuous time and discrete time. Fast heuristic methods are proposed with the relaxation of the machine capacity. For the integrated resource allocation and scheduling problem, a linear programming relaxation approach is applied to solve …

A Globally Convergent Numerical Method For Coefficient Inverse Problems, Natee Pantong
A Globally Convergent Numerical Method For Coefficient Inverse Problems, Natee Pantong
Mathematics Dissertations
In our terminology "globally convergent numerical method" means a numerical method, whose convergence to a good approximation for the correct solution is independent of the initial approximation. A new numerical imaging algorithm of reconstruction of optical absorption coefficients from near infrared light data with a continuous-wave has been purposed to solves a coefficient inverse problem for an elliptic equation with the data generated by the source running along a straight line. A regularization process, so-called "exterior forward problem", for preprocessing data with noise on the boundary has also been purpose for the problem related to matching fluid in experiment. A …
