How to Prepare for the College Board Achievement Test: European History and World Cultures

Book Description

Love poetry dominated European literature during the Renaissance. Its attitudes, conventions, and values appeared not only in courtly settings but also in the transatlantic world, where cultures were being built, power exercised, and policies made. In this major contribution to our understanding of both the Age of Exploration and early modern lyric, Roland Greene argues that love poetry was not simply a reflection of the times but a means of cultural transformation.

European encounters with the Americas awakened many forms of desire, which pervaded the writings of explorers like Columbus and his contemporaries. These experiences in turn shaped colonial society in Brazil, Peru, and elsewhere. The New World, while it could be explored, conquered, and exploited, could never really be "known"—leaving Europe's desire continually unrequited and the project of empire unfulfilled.

Using numerous poetic examples and extensive historical documentation, Unrequited Conquests rewrites the relations between the Renaissance and colonial Latin America and between poetry and history.

From the author: For rheometry and polymer processing applications, it is important to correlate fluid material properties with extrusion parameters like pressure buildup and revolutions per minute. Previous attempts to obtain such correlations have resorted to numerical techniques or approximate relationships. Here we show that upon a suitable rotation of coordinate axes, analysis of the metering zone in closed-discharge single-screw extrusion is simplified. Taking advantage of such simplification, we have derived an analytic. self-consistent relation between fluid properties and extrusion parameters. where the power-law model is used throughout the analysis.

From the author: This work aimed at developing a new instrument to measure in real time the residence time distribution (RTD) in screw extruders. The instrument followed the same principle as the one reported in the literature but possessed several important advantages. For example, the detection system had two probes that allowed to simultaneously measure RTDs at any two different locations of an extruder, thus providing the possibility of calculating the local RTD between them by a deconvolution method based on a statistical theory for the RTD. Its performance was evaluated on a corotating twin-screw extruder using anthracene as tracer and polystyrene as flowing material. The effects of various process parameters such as feed rate and screw speed on the RTDs were investigated. The emphasis was placed, however, on the effect of the staggering angle of kneading discs on local RTDs both in the kneading zone itself and its neighboring upstream and downstream screw zones. This work is in support of an ongoing project on the simulation of flow in corotating twin-screw extruders. POLYM. ENG. SCI., 46:510-519, 2006. [c] 2006 Society of Plastics Engineers

From the author: We present numerical simulations for an acrylonitrile-butadiene-styrene copolymer (ABS) resin extrusion in an industrial conventional single-screw extruder. Based upon the flow field patterns obtained in the simulations, a particle tracking procedure was employed to obtain information about the spatial distribution of particle tracers of two colors. Results of the simulation were compared with experimental data obtained under similar extrusion conditions. To evaluate the degree of color mixing and color homogeneity for the system, we employ a specific index calculated based upon the Shannon entropy for two species populations. POLYM. ENG.

From the author: Ternary blends of PS and PMMA in a PE matrix were prepared by twin-screw extrusion to investigate the core/shell encapsulation phenomenon in the composite droplet. The PS was found to encapsulate the PMMA to form composite droplets within the PE matrix as expected from the spreading coefficient theory. The effects of dispersed phase concentration, viscosity ratio, feeding sequence and twin-screw operating conditions were investigated. The blend morphology was observed by scanning electron microscopy after selective extraction of either PS or PMMA, and average core and composite droplet diameters were determined by image analysis. Although it is known that the structure of composite droplet blends can be substantially altered through control of the volume fraction of the components in the dispersed phase, this study demonstrates that blends with a 1:1 composite droplet volume fraction are relatively stable to large variations in the minor phase viscosities and processing conditions. Twin-screw extrusion thus provides a highly robust technique for the melt processing of blends possessing composite droplet morphologies. Polym. Eng. Sci. 44:749-759. 2004.

From the author: A theoretical model for the cationization of plasticized wheat starch in a modular self-wiping co-rotating twin screw extruder was developed. Our objective was to build a model which would be able to predict the evolution of the cationization reaction along the screws, in relation with the processing conditions and the geometry of the twin screw extruder. Based on previous studies on reactive extrusion modeling, the present model takes into account the interactions occurring between the flow conditions encountered in the extruder and the kinetics of the reaction. It allows one to predict the influence of operating parameters such as reagent concentrations, feed rate, screw speed, and barrel temperature on the reaction extent. Depending on conditions, degrees of substitution in the range 0.01-0.05 are obtained, with efficiencies between 30 and 90%. A good agreement is found between theoretical results and experimental measurements, allowing future use of the model for optimization and scale-up purposes. POLYM. ENG. SCI., 47:112-119, 2007.

From the author: The control of the morphology of an immiscible polymer melt is of vital importance for the mastering of the final properties of the product. As polymer blends are produced using corotating twin-screw extruders, understanding and modeling the changes experienced by the blend during this process is of great interest. In the present study, starting from Ludovic software, developed for computing flow parameters in the twin-screw extrusion process, we present a computation of the droplet morphology development, based on the basic mechanisms of break-up and coalescence. Depending on the value of a local capillary number and on local flow conditions, different changes may occur: affine deformation, drop splitting, break-up by capillary instability, and coalescence. It is thus possible to follow, all along the screws, the changes in morphology, either for a single particle or for a particle distribution. Examples of these different computations are presented and compared with experimental results. Generally speaking, orders of magnitude of droplet size and tendencies when modifying processing conditions are correctly described, but the model still suffers from the absence of description of the melting process.

From the author: The copolymerization of n-butylmethacrylate with 2-hydroxypropylmethacrylate was studied in a closely intermeshing counterrotating twin-screw extruder. The average molecular weight of the product can be increased by increasing the screw rotation rate or the die resistance or by decreasing the throughput or the barrel temperature. The conversion can be improved by decreasing the throughput, increasing the die resistance, and (within limits) increasing the barrel temperature, as well as through post-initiation. Compared with various classical polymerization processes, this situation requires that particular attention be paid to the occurrence of a gel effect, the existence of a thermodynamic ceiling temperature, and the reactivity ratio of the monomers used.
