Optical Methods for the Determination of Combustion Temperatures
A brief survey is presented of optical methods for the determination of temperatures which can be used in rocket engines. The data are presented in outlines and include an outline of basic principles involved in application of a given technique, a sketch of the experimental arrangement, and key references which should he consulted for further details
The Place of Blocks in the Early Childhood Curriculum: Do We Need a New Set of Free Wooden Blocks?
The central place of blocks as important and valuable materials in Western early
childhood settings is well established. Literature includes statements that comment
on both the value of block play for individual children, and the central place of
blocks within group settings. Fry (1992) has noted "the quality of the child absorbed
in self initiated block play activity, and the warm satisfied smiles of achievement and
recognition" (p. 3), and Stritzel (1995) has posited that the "block center can be the
most exciting place in the early childhood classroom" (p. 42). Blocks have been
considered "the most useful and versatile ...toy or product ...in an early childhood
program" (Karges-Bone, 1991, p. 5). In particular, multiple unit blocks' have been
noted as the most important (Starks, 1960), the most useful and the most used
equipment (Kinsman & Berk, 1979, cited in Fry, 1992), as well as being accepted in
varied settings internationally as "one of the finest learning tools available to
children" (Cartwright, 1988, p. 44).
In this paper I argue that there is a case for a new set of free wooden blocks for
infants, toddlers and young children. I have chosen the term free wooden blocks to
indicate pieces of wood which can be freely placed together. This paper provides a
brief outline of literature relating to such blocks and discusses the place of blocks in
the current curriculum context of Te Whariki. The place of blocks as a traditional
play material within Te Whariki is exemplified through an exploration of the strand
of well-being. A conceptual design of a new set of free wooden blocks is then
proposed
A True and Lonesome West: The Spaces of Sam Shepard and Martin McDonagh
In this project, I explore how Sam Shepard and Martin McDonagh treat concepts of space (both on stage and within a larger context that expands beyond the theatre), and I seek to identify how underlying anxieties about a mythologized past become manifest in the relationships between characters and landscapes by examining heterotopic and liminal elements in their scripts

The Meaning of White Flesh: Personhood, Solidarity and Evil as White-Embodied-Being
This paper wrestles with the theological implications of the way that violence makes itself present in white bodies. It is an effort to confront with the meaning of a present reality – the way in which bodies are racially marked – that has roots in particular lived experiences of the past, which live on in the form of triggering, hauntings and trauma. This paper argues that the rejection of body–spirit/soul/psyche/mind dualism and person–world dualism, grounded in the Incarnation of Jesus Christ and expressed in the Shawn Copeland’s non-dualistic category of “black-embodied-being-in-the-world,” makes it necessary to understand white embodiment through a parallel category of “white-embodied-being-in-the-world,” instead of other terms (such as “whiteness”) often used to characterize the “problem of white people.” This paper suggests an ethical response by white-embodied-being-in-the-world rooted in the particularity of white persons’ implication in incidents of subjugation. Noting that some of those subjugations involve harm from white bodies simply by virtue of their presence, and following Ivone Gebara’s understanding of evil as being present “in the daily run of what is harmful to actual persons,” this essay concludes that the white body presents a problem of evil, a problem of theodicy, and that any possible white solidarity must proceed from a candid assessment of that fact. Considering several responses to this circumstance, I examine three responses: Jennifer Harvey’s response rooted in the commands of Jesus, a dialectical response modeled on Irving Greenberg’s response to the Holocaust, and an erotic response derived from Copeland and Audre Lorde. Weighing the strengths and weaknesses of each, I tentatively propose an erotic, dialectical solidarity as ethical response from white-embodied-being-in-the-world
Structure and Emplacement of Cretaceous Plutons in Northwest Yosemite National Park, California
The ~103-98 Ma Yosemite Valley Intrusive Suite, younger Granodiorite North of Tuolumne Peak, and ~97 Ma Yosemite Creek Granodiorite intrude plutonic and metasedimentary host rocks of the central Sierra Nevada batholith. Precambrian to Cambrian metasedimentary rocks separate the Yosemite Valley Intrusive Suite from the younger (94-85 Ma) Tuolumne Intrusive Suite and are interpreted to represent the original extent of the older suite. The Mt. Hoffman granodiorite and Taft Granite of the Yosemite Valley Intrusive Suite record evidence of the development of magma chambers, whereas the Tuolumne Peak and Yosemite Creek granodiorites were likely constructed via several small increments, and a sizable magma chamber did not form. Accommodation of magma was probably facilitated by a combination of processes, but there is only direct evidence for minor stoping. The dominant northwest-striking magmatic foliation in the Mt. Hoffman granodiorite records regional northeast-southwest shortening strain. Variations in strike of magmatic foliation in the Taft Granite likely results from a combination of regional strain and internal processes within a magma chamber

Testing Management-Oriented Hypotheses with Simulation Models
Author Institution: College of Forestry and Natural ResourcesWe need to manage and to use our renewable resources more wisely and yet more intensively in the future. To do this we need to incorporate more of our experience, our data, and our theory into the decision-making process. We can use simulation models in this synthesis effort to advantage. We can perform management experiments with ecosystem level models, generate meaningful output from those experiments, and condense and interpret this output in a manner useful to the management agency personnel. The result will be better resource management decisions based on scientifically and technically defendable information which will have greater internal consistency and which will produce better results under many conditions

Simulation of Locking Space Truss Deployments for a Large Deployable Sparse Aperture Reflector
Large deployable space structures require an inordinate amount of effort to fully design and test on Earth. To aid in the determination of the feasibility of the reflector, a method to simulate the structure\u27s deployment was developed using COMSOL. The simulation model is comprised of a locking hinge truss that constitutes the partial reflector structure. To meet computational and temporal restrictions, the structure is simplified to use simple beams with square cross sections and is meshed to a sufficient accuracy with second order elements. The geometry is modeled in the truss\u27s stowed configuration, with the connecting hinges and applied forces created via constraint equations in COMSOL. Many different simulations were run with varied design parameters in order to demonstrate the global motion of the deploying truss under differing conditions and to also showcase the capabilities of COMSOL\u27s implicit solver. It was found through all of the simulation variations that the success of the truss\u27s deployment is largely dependent on the condition of the lower truss members as well as the interaction between the spring-loaded hinges and tension cables. The results demonstrate how COMSOL can be used to aid in the advancement of the Large Deployable Space Aperture Reflector design
