Item Prediction of drop sizes in liquid/air systems(University of Missouri--Columbia, 1974) Chen, Der-rong; de Chazal, L. E. MarcThree liquids, water, ethylene glycol and 2-ethyl-l-hexanol were dispersed separately through five different sizes of nozzle tips ranging from 0.2 to 0.6 centimeter into vapor-saturated air in various flow rates to determine drop sizes. About four hundred data points were collected to predict drop sizes from the physical properties of liquids and flow rates. A hypothesis is presented which accounts for the effect of inertial mass on drop formation. With this hypo thesis drop sizes can be predicted and the average of 3.5% error is obtained. The maximum error being 12.5% and only 12 points have an error greater than 10%.Item Elkanah Settle's The World in the Moon : a critical edition(University of Missouri--Columbia, 1974) Reser, Loren D.; Anderson, Donald K., Jr.This dissertation investigates Restoration dramatic opera from its beginnings in the Commonwealth, considers the culmination of the form in the productions of Henry Purcell, and finally examines those works presented at the close of the century to provide a context for an understanding of Elkanah Settle’s The World in the Moon (1697). Chapter I explores the various attempts at defini tion of the English compromise in dramatic opera, a mixture of sung and spoken dialogue which, for the English, was necessary to give primacy to the word as opposed to the Italian technique of all-sung opera. The chapter further examines the criticism which surrounded this new generic form. Chapter II deals with the influence of the masque as the predecessor of the dramatic opera? its emphasis on music and dialogue, in combination with elaborate scenery and dance, provided the basic components of the later Res toration dramatic opera. The gradual usurpation of the poetry by the scenes and the triumph of Inigo Jones over Ben Jonson, provided a foreshadowing of what occurred in the dramatic opera after the death of Purcell. Chapter III offers a survey of the musical works of William Davenant, generally considered to be the founder of English opera. Davenant's position in the history of dramatic' opera is important because he provides a link between the masques of the court of Charles I and the public stage of the Restoration. His First Day's Entertainment and The Siege of Rhodes were important as the first truly operatic works of the period, despite the restrictions imposed upon him by the Puritans. His early works after the opening of the theatres in 1660, Siege, Macbeth and The Tempest, began the sporadic history of dramatic opera in the Restoration. Chapter IV examines those dramatic operas produced between 1660 and 1685, works which were without rules to govern their creation and which were tentative explorations in form. Most were artistic failures; but Shadwell's Psyche, produced in 1675, offered the most successful solution to the problem of reconciling and synthesizing the diverse elements of the operatic form. The model established by Shadwell inexplicably was not followed between 1675 and 1690, and it was not until the productions of Henry Purcell that Shadwell's prototype was successfully emulated and brought to the heights of its artistic potential. Chapter V deals mainly with the works of Henry Purcell which, beginning with Dido and Aeneas in 1689, brought the dramatic opera form to its full artistic culmina tion. The greatest dramatic opera. King Arthur (1691), in collaboration with John Dryden, achieved the synthesis of music, drama and scene which had been lacking in earlier works. His music for Dioclesian, The Fairy Queen, Bonduca, and The Indian Queen dominated the stage during the early 1690’s. His untimely death in 1695 left England without a musical successor to equal his talents; the dramatic opera slowly lapsed into a degenerate form, allowing the music and scenes to dominate over the drama, thus denying the equal roles that these elements had played in King Arthur. Those operas produced after Purcell's death, including The World in the Moon, are evidence of the gradual corruption of ths form. Chapter VI describes Settle's career and examines The World in the Moon as dramatic opera. The reasons for Settle's unusual synthesis of comedy and opera and the work's place in the context of English dramatic opera are discussed. An examination of Settle's other dramatic operas, The Virgin Prophetess (1701) and The Lady's Triumph (1718), is also included. The Virgin Prophetess was the last dramatic opera of the Restoration; with its production, the English compro mise had run its full spectrum of genesis, culmination and decay. The Lady's Triumph was produced after the domination of Italian opera in England and cannot be considered among its Restoration predecessors. Chapter VII examines the text of The World in the Moon and especially concentrates on the so-called "second edition." Collation of eight copies of the play, six of the first edition and two of the "second edition," proves that there was no second edition of the play but that those copies described as a "second edition" were simply a further im pression of the first with an altered title-page. Other textual problems are explored, the possibility of a second compositor, for example. A discussion of the musicians, Daniel Purcell and Jeremiah Clark, and their music for The World in the Moon is included. To provide the most correct text, portions of copies from the Newberry Library and the University of Chicago Library have been conflated. Textual and explanatory notes are included. The two folio editions of the music for the single songs in The World in the Moon are reproduced in an appendix.Item A vertical coordination analysis of meat distribution in the food service industry(University of Missouri--Columbia, 1979) Jones, Michael Alan; Rhodes, V. JamesThe market channel for meat, after the packer stage, is divided into two basic alternate channels or segments. Of these two market channels, the largest consists of those meat products distributed for sale in retail grocery outlets. The smaller, which represents about one-third of the total dollar value of meat products sold, is made up of meat products which are sold to food service operations for away-from-home preparation and consumption. This is a study of the latter of these two market channels. The focus of the study is on firms in the final two stages of the food service market channel for meat, and the vertical coordination between these two stages. The first of these two stages, or sellers in this case, was designated the distribution stage. These intermediary firms purchase meat from packers, fabricate it, and process it if necessary, to the needs of food service users. They then serve as purveyors or suppliers to food service operations (restaurants, cafeterias, hospitals, etc.). The latter of the two stages, or buyers in this case, consists of the various types of food service operations who prepare and serve the meat. This study has two objectives. The first is to characterize the organization of the market, including structure and market channels, as well as to describe vertical coordination, behavior, and performance. The second objective is to test the hypothesis that a relationship exists between the degree of "tightness" of vertical coordination and economic efficiency. Primary data were collected through use of a questionnaire administered by personal interviews with relevant management personnel representing firms from both stages studied. Separate questionnaires were developed for each stage. A stratified random sample of observations was taken from those food service operations located in the Metropolitan Kansas City, Missouri, area. Almost the entire population of firms at the distributor stage was obtained in the sample. Regarding the horizontal structure of the market, it was concluded that both stages were characterized by monopolistic competition, however, features of oligopoly and pure competition were present. Participants were price-makers, products were differentiated, sellers were aware of the behavior of their competitors, and some degree of market concentration existed among sellers. Price inelasticity of demand was found to exist regarding individual sellers price actions. However, as in pure competition, many buyers existed meaning no particular one could exert a significant influence on the market. No domination existed among firms at either stage. Significant barriers to entry did not exist, and some degree of nonprice competition existed. A variety of types of vertical coordination exist in this market. Buyers range from small independent firms using market exchange as a means of coordination, to fully vertically integrated corporately owned "chain" operations. Between these extremes, coordination consists of contractual arrangements varying in type and degree of specification. As to the extent of vertical integration between the distributor-operator stages of the industry, this study indicated that not enough was present to have caused the market to deteriorate to an anticompetitive extent. Over half of the volume was transacted through competitive market exchange in what appeared to be a "healthy" market. Actually, a relatively small percent of meat was distributed through completely integrated firms. Contracts using formula pricing represented a relatively small portion of exchange, likewise. Regarding the second objective, an efficiency ratio was developed using time spent on the buying function per week and prices paid by buyers, to compare efficiency between three types of vertical coordination: market exchange, contractual integration of limited degree, and vertically integrated firms. To determine the existence of a relationship between type of coordination and efficiency, a regression model was used. The relative magnitudes of the efficiency coefficients generated for each of the three types of coordination supported the hypothesis. Though more efficiency was indicated for the two groups having tighter forms of coordination, a low significance level was not obtained, probably due to small sample size.Item Background and applications of the honor code in Dryden's four Spanish-oriented heroic plays(University of Missouri--Columbia, 1973) Campbell, Dowling G.; Anderson, Donald K.The treatment of honor in John Dryden’s four Spanish oriented heroic plays--The Indian Queen, The Indian Emperour, and both parts of The Conquest of Granada--follows dramatic patterns conspicuously parallel to those in earlier Spanish plays. From a basic complexity involving the dichotomy in types of honor to such specific elements as the blood rite, vengeance, conflict, reputation, the vow, the slander, and others, motifs abound in these four Dryden plays that abound also in the most popular plays of such renowned Siglo de Oro playwrights as Lope de Vega, Tirso de Molina, and Calderon. These motifs function in sufficiently explicit detail to suggest a deliberate borrowing on Dryden’s part. Such influence from Spanish drama has been largely ignored since no proof that Dryden could read the language has been previously documented. Dryden’s own acknowledgment that he can read Spanish, however, validates potential arguments hitherto discounted. While detailed analyses of possible analogues to these four heroic plays lie beyond the scope of my study, certain plays, such as Lope’s El perro del hortelano or La envidia de la nobleza, are suggested. The ethics of Dryden’s honor code expands, of course, far beyond these two plays. French tragedy, long considered by most Dryden critics as the sole supplier of outside influence for all his heroic plays, does not supply explicit character reactions to the honor code. Neo—Platonism cannot adequately explain or account for the dynamic behavior of such characters as Montezuma, Cortez, or Almanzor. Nor was Spanish influence channeled to Dryden through French playwrights. Spanish drama influenced only French comedy, and then the motifs were altered to fit Continental manners. Indeed, when Corneille early attempted to inject some authentic Spanish ethics and attitudes into Le Cid, he was soundly rebuked by Cardinal Richelieu’s Academy. No appreciably Spanish motifs appear in serious French drama thereafter. Dryden’s borrowings from Spanish literature should come as no surprise. Tudor and Stuart drama contain a rich legacy of Spanish references ranging from courtesy books and histories to novels and plays. Peninsular themes increase in popularity with the Restoration. Coupled with his ability to read the language, this popularity renders Dryden’s treatment of honor in his four heroics as all the more convincing evidence that he was strongly influenced by Spanish literature, and especially by Siglo de Oro playwrights.Item Isolation and characterization of Streptococcus uberis of bovine mastitis origin(University of Missouri--Columbia, 1970) Misra, Bhagirathi; Marshall, R.T."Thin, watery, large mucoid colonies on blood agar plates, gram variable cocci in long chains, inability to grow in common laboratory media--these were among the un usual observations made in May, 1968 in the investigation of an outbreak of mastitis. At one milking visibly abnor mal milk appeared in 33% of the quarters of the herd. Counts of the causative organism were often 10^6/ml. Due to mastitis, acute in nature, most of the animals had to be sold during two years time. The organism was penicillin sensitive, but treat ment with penicillin did not eliminate the malady. Milk samples taken 12 months apart yielded two mucoid strains, biochemically classified as Streptococcus uberis. The recurring attacks resulted in severe economic loss to the owner. The problem was so intriguing and baffling that it was decided to investigate the outbreak, to identify the causative organism and to suggest remedial measures. Because the isolates were very unusual, it was chosen to study them in detail. Two non-mucoid strains were evolved from the wild types making comparisons to the mucoid strains possible. Study of the gram reaction was planned using various media and reagents. Sensitivities to various antibiotics were observed. Persistency of the outbreak, in spite of treatment, demanded an epidemiological survey. Attempts were made to study the immunological behavior and the pathogenicity for experimental animals. Although Str. uberis ranks second to Str. agalactiae in the etiology of mastitis, it has so far evaded a logical classification. Str. agalactiae, being more common and comparatively more easily identified, has usually been the subject of mastitis investigations rather than Str. uberis. No single Lancefield serum will type all its strains. Much of the literature on this organism is contradictory in nature, and most workers have been primarily interested in taxonomy. Str. uberis causes severe outbreaks of bovine mastitis and elicits poor immunological response. Mere mention of its name along with other organisms as the causative agent of mastitis does not mean much. Thus the organism was studied in detail, and the results of this investigation are embodied in this thesis. It is hoped that this work will clear up some of the confusion existing about this organism."--Introduction.
