Demonstration of a sterilizable solid rocket motor system, addendum

Technical emphasis was placed on characterization of a scaled-up batch of the improved propellant formulation and determination of the effects of dry heat sterilization on propellant integrity and structural response. The grain stress analysis was directed toward tailoring a fully-bonded grain to the calculated propellant allowable stresses and investigating various bond release concepts to relieve stresses incurred in thermal shrinkage following sterilization

Cue the Music: Music in Movies

Music in movies has a significant impact on the viewer’s perception of what is happening by providing musical cues about characters, moods, and plot foreshadowing. Movies today are a major source of American entertainment. The purpose of this paper is to attempt to show that music in movies has a large impact on the audience watching movies. And is therefore used as a device to guide emotions and foreshadow plots. The paper will attempt to prove this by answering the following questions. One; in what way is music used in movies to provide plot cues and foreshadowing? Two; how does music in movies provide musical cues about characters and their intentions? And finally, what typical musical devices, (intervals, instruments, musical progression, and chords) are used to signal different movie moods and events? By answering these questions this paper will endeavor to show that music is not only an expected part of the part of the cinematic experience but that it has become something that is integral to watching movies. Various research articles as well as audio examples were studied and analyzed to provide the basis for the statistics and examples involved in this paper

Synthesis and alkyne-coupling chemistry of cyclomanganated 1- and 3-acetylindoles, 3-formylindole and analogues

The syntheses are reported of new cyclomanganated indole derivatives (1-acetyl-κO-indolyl-κC2)dicarbonylbis(trimethylphosphite)manganese (2), (1-methyl-3-acetyl-κO-indolyl-κC2)tetracarbonylmanganese (4), (3-formyl-κO-indolyl-κC2)tetracarbonylmanganese (5a) and (1-methyl-3-formyl-κO-indolyl-κC2)tetracarbonylmanganese (5b). The unusually complicated crystal structure of 5b has been determined, the first for a cyclomanganated aryl aldehyde. The preparations of a mitomycin-related pyrrolo-indole and related products by thermally promoted and oxidatively (Me3NO) initiated alkyne-coupling reactions of the previously known complex (1-acetyl-κO-indolyl-κC2)tetracarbonylmanganese (1) are reported for different alkynes and solvents. X-ray crystal structures are reported for the dimethyl acetylenedicarboxylate coupling product of 1 (dimethyl 1-methyl-l-hydroxypyrrolo[1,2a]-indole-2,3-dicarboxylate; 6a), and an unusually-cyclised triple insertion product 8 from the coupling of acetylene with 4, in which a cyclopentadiene moiety is η3-allyl-coordinated to Mn through only one double bond and an exocyclic carbon, but which rearranges on heating to an η5-cyclopentadienyl complex

Daily Practice1: Ethics In Leadership

The classic question, “Should business schools teach ethics?” is not often asked anymore given the drip, drip, drip of business corruption reported in the news. Even skeptics allow that business ethics education could not hurt and might improve the ethics of business leaders. Furthermore, universities, colleges, and business accrediting agencies prominently represent their ethics for all to see in standards, codes, handbooks, and advertisements. They seem to promote ethical conduct at their institutions. But how do faculty and administrators actually behave? And if not ethically, what are the educational lessons new professionals take to the workplace?&nbsp

Video-recording for therapeutic purposes in couple counselling

The challenges of producing fair and respectful relationships sometimes takes couples to counselling. Problematic and taken-for-granted, individualistic, adversarial and gendered discursive practices continue to get in the way of fair and respectful relationships, with studies showing that in heterosexual relationships women are often expected to do most of the work required to maintain and repair couple relationships which continue to centre men’s experiences. When couples get to counselling, counsellors may also struggle to address individualistic and gendered relational processes and, may reproduce them despite their best intentions. In response, narrative therapists work with clients to externalise and deconstruct discursive practices to make visible the operation of power in relationships and to make available other readings, ways of being and identities, which better position members of a couple to collaborate in order to produce solutions. This study employed narrative therapy co-research and video technology in order to investigate the researcher’s own narrative therapy counselling practice with couples. Three couples, all heterosexual, in marriage or marriage-like relationships, were recruited from the researcher’s counselling practice. Together the couples and researcher reviewed and co-researched the video records of the counselling meetings. Practices of co-research with video made visible and unfamiliar some previously unseen and taken-for-granted territories of life. Co-research of these territories generated understandings and proposals for action, which the couples then experimented with and reviewed. As well, the couples all began to imagine how their actions might appear on video and to adjust their actions and thinking to better fit with their values. The video records also provided a text for further deconstructive analysis. Within the counselling, re-membering conversations, taking-it-back practices and definitional ceremonies, were employed and enhanced by using the video in order to support preferred developments and to strengthen the contributions of children, family and communities to the couples’ preferred ways of being. This approach was used to investigate: the ways the couples shared and conducted their conversations in counselling; their parenting; an anger problem; and the sharing of property and income. Ongoing analysis of the video records and transcripts developed and extended the theoretical tools available in the moments of the counselling, producing a richer telling of a practice that was effective at the time. This retelling involved thinking with Derrida and deconstruction as justice in order to cast counselling as an hospitable, collaborative process of co-research which has as its focus addressing justice in the complex, relational, gendered, cultural and contextual territories in which couples’ relationships are played out. The thesis argues that the positioning of counsellor and couples as co-researchers, using hospitable and deconstructive perspectives, greatly reduced conflict and equipped the counsellor and couples to review and research their own experiences, and to collaborate in order to produce more effective problem solving strategies, which addressed their situations and their hopes for justice

Predicting functional properties of milk powder based on manufacturing data in an industrial-scale powder plant

The fundamental science relating key physical and functional properties of milk powder to plant operating conditions is complex and largely unknown. Consequently this paper takes a data-driven approach to relate the routinely measured plant conditions to one vital function property known as sediment in an industrial-scale powder plant. Data from four consecutive production seasons was examined, and linear regression models based on a chosen set of processing variables were used to predict the sediment values. The average prediction error was well within the range of the uncertainty of the laboratory test. The models could be used to predict the effect of each individual plant variable on the sediment values which could be beneficial in quality optimisation. In addition the choice of the training data set used to compute regression coefficients was studied and the resultant regression models were compared to alternative PLS models built on the same data

Significance of powder breakdown during in-plant transport at industrial milk powder plants

Instant whole milk powder (IWMP) is designed to rapidly dissolve in water, which depends on the particle size distribution (PSD) and agglomeration. The warm and delicate milk powder exiting the dryer is transported via either pneumatic conveying or bucket elevators to packing. The gentleness of this powder transport process is important for IWMP, as it can break down the agglomerates, generating excess fines, which leads to poor dissolution properties. This work looked at the breakdown of milk powder at two different, geographically separate, industrial IWMP plants, using the Malvern Mastersizer, a laboratory laser diffraction instrument, and sieving, to evaluate the importance of breakdown on the final product properties given different conveying methods. It was found that the method of measurement affected the results, with sieves showing a larger powder size reduction during transport as compared with the Mastersizer. PSDs with a larger average size at the start of powder transport showed more breakdown, with a greater decrease in the average particle size. However, the larger decrease was not enough to compensate for the initially larger average particle size, and powder that started out with larger agglomerates at the fluidised beds still had a larger average particle size at packing. The Mastersizer appeared to break the large agglomerates during measurement, especially with powder that had not been through the entire transport line, thus masking the extent of the size reduction, however this could only occur to weaker agglomerates. Thus in order to produce IWMP with the desired functionalities, the focus should be on improving agglomeration as oppose to reducing transport breakdown to achieve the desired particle size distribution
