Principles in Patterns (PiP) : Institutional Approaches to Curriculum Design Institutional Story
The principal outputs of the PiP Project surround the Course and Class Approval (C-CAP) system. This web-based system built on Microsoft SharePoint addresses and resolves many of the issues identified by the project. Generally well received by both academic and support staff, the system provides personalised views, adaptive forms and contextualised support for all phases of the approval process. Although the system deliberately encapsulates and facilitates existing approval processes thus achieving buy-in, it is already achieving significant improvements over the previous processes, not only in reducing the administrative overheads but also in supporting curriculum design and academic quality. The system is now embedded across three faculties and is now considered by the University of Strathclyde to be a "core institutional service". Alongside the C-CAP system the PiP Project also cultivated a suite of approaches: an incremental systems development methodology; a structured and replicable evaluation approach, and; Strathclyde's Lean Approach to Efficiencies in Education Kit (SLEEK) business process improvement methodology Each is based on recognised formal techniques, providing the basis for a rigorous approach. This is contextualised within and adapted to the HE institutional context thus building the foundation not only for the project but ultimately for institution wide process improvement. This "institutional story" report summarises the principal outcomes of the Project
Occurrences of \u3ci\u3eEumorpha Fasciata, Hyles Gallii, Sphinx Franckii\u3c/i\u3e and \u3ci\u3eS. Vashti\u3c/i\u3e (Lepidoptera: Sphingidae) in Illinois
A recent survey of private and institutional collections in Illinois and surrounding states has provided specific information on the occurrences of four species of sphingids within Illinois: Eumorpha fasciata, Hyles gallii, Sphinx franckii, and S. vashti. Geographical and phenological data for these species are provided
Limits on violations of Lorentz Symmetry from Gravity Probe B
Generic violations of Lorentz symmetry can be described by an effective field
theory framework that contains both general relativity and the standard model
of particle physics called the Standard-Model Extension (SME). We obtain new
constraints on the gravitational sector of the SME using recently published
final results from Gravity Probe B. These include for the first time an upper
limit at the 10^(-3) level on the time-time component of the new tensor field
responsible for inducing local Lorentz violation in the theory, and an
independent limit at the 10^(-7) level on a combination of components of this
tensor field.Comment: 8 pages, 1 figur
Heat transfer and combustion in a two-bed fluidized combustor
Fluidized bed combustion has grown with the prospect that it can burn coal and low grade fuels in an environmentally acceptable manner. Among the technical problems that exist, however, is the inherent inability to produce large variations in heat transfer rate from the fluidized bed. Generally, changes in heat transfer rate (load turndown control) by conventional means are modest and are accompanied by degradation in combustion;The objective of this research was to investigate a new concept in fluidized bed design that improves load turndown capability. Load turndown ratio is defined as the ratio of maximum to minimum fuel firing rates. Load turndown improvement was accomplished by independently controlling heat transfer and combustion in the combustor. The design consisted of two fluidized beds: one central and one annular bed. The central bed served as the combustion bed. The annular bed was fluidized separately from the combustion bed and its level of fluidization determined the overall heat transfer rate from the combustion bed to a surrounding water jacket. Simple theoretical considerations suggested a load turndown ratio exceeding ten was possible for this design;A computational model consisting of energy and mass balances and a simple combustion kinetics model for the two-bed combustor were developed to predict the detailed performance of the combustor and to assist in the design of the unit. Combustion tests were performed in an optimally-designed combustor. Three coal-based fuel forms were used: crushed coal, coal-limestone briquettes, and coal-water-limestone mixture (CWLM). A load turndown ratio of 12.3 was obtained while burning crushed coal. Slightly lower turndowns were obtained for briquettes and CWLM. Sulfur dioxide emission reductions ranging from 42% to 93% were observed for a fuel calcium-to-sulfur molar ratio of 2.0. For most tests, emissions of NO[subscript] x and SO[subscript]2 met EPA New Source Performance Standards. Computer model predictions were in reasonable agreement with experimental observations
Instrumentation of a shock tube facility
The theory of schlieren and interferometer systems was described and related to studies of shock waves in a shock tube. An interferometer was procured and a schlieren system was modified for use with the UMR shock tube facility. The design and construction of a base for the systems and window assemblies for the shock tube comprised the major portion of the work on this project. A short series of tests were run to ascertain the compatibility of the instrumentation to the UMR shock tube facility. While no schlieren photograph of the shock wave was obtained, the system was shown to be operating properly. The piezoelectric pressure transducers used in conjunction with a dual beam oscilloscope provided a record from which shock velocity and strength could be calculated. Test results were compared were possible to theoretical values and very good correlation was obtained --Abstract, page ii

Book Review: Chaos and Grace: Discovering the Liberating Work of the Holy Spirit by Mark Galli
Identifying the ways in which God’s Spirit maneuvers and works in the world has never been a task undertaken with ease by the committed faithful. Yet, this is exactly what author Mark Galli, current Senior Managing Editor at Christianity Today, attempts to do in his latest publication, Chaos and Grace: Discovering the Liberating Work of the Holy Spirit. With a foreword written by Will Willimon, former chapel dean at Duke Divinity School, this book completes the third and final volume in Galli’s series on the Trinity. The former two works in this Trinitarian trilogy address, first, Jesus Christ in Jesus Mean and Wild: The Unexpected Love of An Untamable God (Baker, 2008) and second, the nature of God, in A Great and Terrible Love: A Spiritual Journey Into the Attributes of God (Baker, 2009). While surely informed by these two previous publications, Chaos and Grace stands on its own as Galli seeks to demonstrate the potentially disruptive and untamed nature of the Holy Spirit—what he terms "holy chaos"—whose power can ultimately transform human lives dominated by a need for constant control and obsessive ordering over their circumstances in all domains of life, including religious life. This "holy chaos" of disorder spawned by movements of the Spirit, which Galli interprets as "gift," serves as a means by which God chooses to both liberate persons from the duties of religion—worship, prayer, scripture reading—and also to relieve persons from their "addiction" to living such overly managed and restrictive lives (18). For Galli, abandoning this detrimental control and appreciating God as the "instigator" of dismantling chaos puts the Christian on the way to living "the life of freedom" which may become a "real possibility" (18-19)
