Two Groups Control Light-Induced Schiff Base Deprotonation And The Proton Affinity Of Asp85 In The Arg82his Mutant Of Bacteriorhodopsin, Eleanora S. Imasheva, Sergei P. Balashov, Thomas G. Ebrey, Ning Chen, Rosalie K. Crouch, Donald R. Menick

MUSC Faculty Journal Articles

Arg82 is one of the four buried charged residues in the retinal binding pocket of bacteriorhodopsin (bR). Previous studies show that Arg82 controls the pKas of Asp85 and the proton release group and is essential for fast light-induced proton release. To further investigate the role of Arg82 in light-induced proton pumping, we replaced Arg82 with histidine and studied the resulting pigment and its photochemical properties. The main pKa of the purple-to-blue transition (pKa of Asp85) is unusually low in R82H: 1.0 versus 2.6 in wild type (WT). At pH 3, the pigment is purple and shows light and dark adaptation, …

Geombinatoric Aspects Of Processing Large Images And Large Spatial Databases, Jan Beck, Vladik Kreinovich, Brian Penn

Departmental Technical Reports (CS)

Computer processing can drastically improve the quality of an image and the reliability and accuracy of a spatial database. A large image (database) does not easily fit into the computer memory, so we process it by downloading pieces of the image. Each downloading takes a lot of time, so, to speed up the entire processing, we must use as few pieces as possible.

Many algorithms for processing images and spatial databases consist of comparing the value at a certain spatial location with values at nearby locations. For such algorithms, we must select (possibly overlapping) sub-images in such a way that …

Evolutionary And Acclimation-Induced Variation In The Heat-Shock Responses Of Congeneric Marine Snails (Genus Tegula) From Different Thermal Habitats: Implications For Limits Of Thermotolerance And Biogeography, Lars Tomanek, George N. Somero

Biological Sciences

Heat stress sufficient to cause cellular damage triggers the heat-shock response, the enhanced expression of a group of molecular chaperones called heat-shock proteins (hsps). We compared the heat-shock responses of four species of marine snails of the genus Tegula that occupy thermal niches differing in absolute temperature and range of temperature. We examined the effects of short-term heat stress and thermal acclimation on the synthesis of hsps of size classes 90, 77, 70 and 38 kDa by measuring incorporation of (35)S-labeled methionine and cysteine into newly synthesized proteins in gill tissue. Temperatures at which enhanced synthesis of hsps first occurred …

An Evaluation Of Ploughing Models For Orthogonal Machining, Daniel J. Waldorf, Richard E. Devor, Shiv G. Kapoor

Industrial and Manufacturing Engineering

An analytical comparison is made between two basic models of the flow of workpiece material around the edge of an orthogonal cutting tool during steady-state metal removal. Each has been the basis for assumptions in previous studies which attempt to model the machining process, but no direct comparison had been made to determine which, if either, is an appropriate model. One model assumes that a separation point exists on the rounded cutting edge while the other includes a stable build-up adhered to the edge and assumes a separation point at the outer extreme of the build-up. Theories of elastic-plastic deformation …

The Edaphic Factor And Patterns Of Variation In Lasthenia Californica (Asteraceae), Nishanta Rajakaruna, Bruce A. Bohm

Biological Sciences

Transectional studies of Lasthenia californica in the Jasper Ridge Biological Preserve (Stanford University) have documented the existence of two races (A and C) based upon flavonoid chemistry, achene morphology, allozymes, and flowering time differences. The two races coexist on a serpentine outcrop and have maintained a sharply defined pattern of distribution for a period of at least 15 yr. The present study has revealed significant differences in the physical and chemical features of the soils harboring the two races. Soils at the lower ends of the transects, where race A plants grow, have higher pH, cation exchange capacity, relative water …

1991-1992 & 1996 Utah Usage Of Ems Services By Children: Year Iii Research Report, Intermountain Injury Control Research Center, U.S. Department Of Commerce

All U.S. Government Documents (Utah Regional Depository)

This study examined how Utah children used emergency medical services (EMS) and related hospital care in 1991-1992. The EMS and hospital records were linked using special software (probabilistic linkage) . The principal findings of the study concerned the care of young children less than 5 years of age. They received fewer procedures prior to being transported to a hospital and required more time at the scene for assessment. Some interventions such as splinting of fractured arms prior to transport to a hospital were related to reduced hospital charges. Ambulance and hospital charges for children were estimated to by $35,000,000 not …

Construct Validity Of The Continuous Recognition Memory Test, K. L. Fuchs, J. H. Hannay, W. M. Huckeba, K. A. Espy

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

A principal factor analysis was performed on variables derived from a neuropsychological battery administered to 100 healthy young adults (aged 17-41 yrs) to investigate the construct validity of the Continuous Recognition Memory test (CRM). It was hypothesized that CRM "hits" and "false alarms" would load on different factors. The factors that emerged in the analysis were labeled Verbal Ability, Divided Attention, Attention to Visual Detail, Visuomotor Integration and Planning, and Learning and Memory. As expected, CRM hits had a significant loading on the Learning and Memory factor. However, CRM false alarms did not have a significant loading on the Divided …

Introduction: Conflict Resolution And Social Justice, Richard E. Rubenstein

Peace and Conflict Studies

A daunting obstacle to clarity in formulating ideas about conflict resolution and social justice is the fact that each of these terms has multiple meanings. There is widespread recognition that "social justice" is a multivalent phrase. Commentators since Aristotle have written of distributive, restitutive, retributive, procedural, and relational justice, and each of these types has been further subdivided to reflect differences in social philosophy and in common usage. Less well recognized is the ambiguity of "conflict resolution," a term that refers to a mélange of theories and practices that, although interrelated, do not constitute a cleanly demarcated and coherently defined …

The Coral Reef Fishes Of Broward County Florida, Species And Abundance: A Work In Progress, B. D. Ettinger, David S. Gilliam, L. K. B. Jordan, Robin L. Sherman, Richard E. Spieler

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The inshore environment of Broward County, FL consists of three coral reef/hard bottom reef tracts, separated by sand substrate, running parallel to the coast in sequentially deeper water. At quarter nautical mile intervals, for a five mile coastline section, fishes were censused at western, eastern and crest sites of each of the three reef tracts. On SCUBA and using the Bohnsack/Bannerot point-count method, we recorded: fish abundance, species richness, size, and general habitat of an imaginary cylinder 15 m in diameter. The position of each site was recorded by DGPS after census. One hundred and eighty-one sites were censused during …

Conflict Resolution And Distributive Justice: Reflections On The Burton-Laue Debate, Richard E. Rubenstein, Frank O. Blechman

Peace and Conflict Studies

Excerpt

From its inception, the field of conflict resolution has appealed strongly to practitioners, researchers, and theorists interested in social betterment. Most conflict resolvers would probably agree that their efforts are motivated, at least in part, by the conception of a Good (or at least a Better) Society considerably less violent and contentious, more peaceful and cooperative, than the existing social order. Many would also affirm that in order to reach this goal, the sources of violence and contention, which include cultural norms sanctioning or glorifying violence, invidious and discriminatory "isms" (racism, sexism, etc.), gross socioeconomic and political inequities, and …

Sensitivity Of Boreal Forest Regional Water Flux And Net Primary Production Simulations To Sub-Grid-Scale Land Cover Complexity, John S. Kimball, Steven W. Running, S. S. Saatchi

Numerical Terradynamic Simulation Group Publications

We use a general ecosystem process model (BIOME-BGC) coupled with remote sensing information to evaluate the sensitivity of boreal forest regional evapotranspiration (ET) and net primary production (NPP) to land cover spatial scale. Simulations were conducted over a 3 year period (1994–1996) at spatial scales ranging from 30 to 50 km within the BOREAS southern modeling subarea. Simulated fluxes were spatially complex, ranging from 0.1 to 3.9 Mg C ha⁻¹ yr⁻¹ and from 18 to 29 cm yr⁻¹. Biomass and leaf area index heterogeneity predominantly controlled this complexity, while biophysical differences between deciduous and coniferous vegetation …
