Structure Of Human Thymidylate Synthase Under Low-Salt Conditions, Leslie L. Lovelace, Wladek Minor, Lukasz Lebioda

Faculty Publications

Human thymidylate synthase, a target in cancer chemotherapy, was crystallized from PEG 3350 with 30 mM ammonium sulfate (AS) in the crystallization medium. The crystals are isomorphous with the high-salt crystals (~2.0 M AS) and the structure has been solved and refined (R = 22.6%, Rfree = 24.3%) at 1.8 Å resolution. The high- and low-AS-concentration structures are quite similar, with loop 181-197 is in the inactive conformation. Also, residues 95-106 and 129-135 (eukaryotic inserts region) show high mobility as assessed by poor electron density and high values of crystallographic temperature factors (residues 1-25 and 108-129 are disordered in both …

Crystalline Particle Packings On A Sphere With Long Range Power Law Potentials, Mark Bowick, Angelo Cacciuto, David R. Nelson, Alex Travesset

Physics - All Scholarship

The original Thomson problem of "spherical crystallography" seeks the ground state of electron shells interacting via the Coulomb potential; however one can also study crystalline ground states of particles interacting with other potentials. We focus here on long range power law interactions of the form 1/r^gamma (0 < \gamma < 2), with the classic Thomson problem given by gamma=1. At large R/a, where R is the sphere radius and a is the particle spacing, the problem can be reformulated as a continuum elastic model that depends on the Young's modulus of particles packed in the plane and the universal (independent of the pair potential) geometrical interactions between disclination defects. The energy of the continuum model can be expressed as an expansion in powers of the total number of particles, M sim (R/a)^2, with coefficients explicitly related to both geometric and potential-dependent terms. For icosahedral configurations of twelve 5-fold disclinations, the first non-trivial coefficient of the expansion agrees with explicit numerical evaluation for discrete particle arrangements to 4 significant digits; the discrepancy in the 5th digit arises from a contribution to the energy that is sensitive to the particular icosadeltahedral configuration and that is neglected in the continuum calculation. In the limit of a very large number of particles, an instability toward grain boundaries can be understood in terms of a "Debye{--}Huckel" solution, where dislocations have continuous Burgers' vector "charges". Discrete dislocations in grain boundaries for intermediate particle numbers are discussed as well.

Expanding The Use Of Cellular Automata, Joseph Bertles

Computer Science Honors Theses

Cellular automata are a type of simulation based upon dividing space into cells. More specifically, cellular automata are characterized by parallelism, locality, and homogeneity. A simulation is run by conducting a series of updates, consisting of running a set of rules that all cells follow. The rules typically consist of looking at a cell's immediate neighbors and/or itself to determine what will be in the cell at the next step. The rules are applied to all the cells at exactly the same time in exactly the same manner. The use of cellular automata has been limited to computer scientists, those …

Preparing Teachers To Create A Mainstream Science Classroom Conducive To The Needs Of English-Language Learners: A Feminist Action Research Project, Gayle A. Buck, Colette Mast, Nancy Ehlers, Elizabeth Franklin

Department of Teaching, Learning, and Teacher Education: Faculty Publications

A feminist action research team, which consisted of a science educator, an English-language learner (ELL) educator, a first-year science teacher, and a graduate assistant, set a goal to work together to explore the process a beginning teacher goes through to establish a classroom conducive to the needs of middle-level ELL learners. The guiding questions of the study were answered by gathering a wealth of data over the course of 5 months and taken from the classroom, planning sessions, and researchers and students. These data were collected by observations, semistructured interviews, and written document reviews. The progressive analysis ultimately revealed that: …

The Anchor, Volume 119.04: September 28, 2005, Hope College

The Anchor: 2005

The Anchor began in 1887 and was first issued weekly in 1914. Covering national and campus news alike, Hope College’s student-run newspaper has grown over the years to encompass over two-dozen editors, reporters, and staff. For much of The Anchor's history, the latest issue was distributed across campus each Wednesday throughout the academic school year (with few exceptions). In recent years The Anchor moved to monthly print issues and a more frequently updated website. The Anchor is now published in print twice per academic semester. Occasionally, the volume and/or issue numbering is irregular.

Hurricane-Forced Upwelling And Chlorophyll A Enhancement Within Cold-Core Cyclones In The Gulf Of Mexico, Nan D. Walker, Robert R. Leben, Shreekanth Balasubramanian

Faculty Publications

Clear skies, subsequent to Hurricane Ivan's passage across the Gulf of Mexico in September 2004, provided a unique opportunity to investigate upper ocean responses to a major hurricane. Oceanic cyclonic circulation was rapidly intensified by the hurricane's wind field (59-62 m s^-1), maximizing upwelling and surface cooling (3-7°C) in two large areas along Ivan's track. Upward isothermal displacements of 50-65 m, computed from wind stress and sea surface height changes, caused rapid ventilation of thermoclines and nutriclines, leading to phytoplankton blooms with peak concentrations 3-4 days later. Wind speed changes along Ivan's track demonstrated that the cool waters …

Teaching Strategies, Learning Strategies, And Communication In The Mainstream Biology Classroom. A Study Of The Perspective Of Deaf Students, Denise Lengyel

Theses

This qualitative pilot research study explores the perceptions of deaf students who are a minority in the mainstream college classroom. It focuses upon the effectiveness of teaching and learning strategies used in the biology classroom, and how communication with hearing peers affects the deaf student's ability to learn in the classroom. Through questionnaires and interviews, participants provided insight on their experiences in the mainstream biology setting. Through research articles and interview responses, suggestions for effective teaching, learning, and communication were constructed and are provided to benefit all in the education profession.
