(4+2)-Cycloaddition Reactions of Ketenes; Pyranones (open access)

(4+2)-Cycloaddition Reactions of Ketenes; Pyranones

This study deals with the (4+2)-cycloaddition reactions of 4-π electron compounds with ketenes. Chloroketenes were generated in situ from the corresponding chlorinated acid chlorides in the presence of the ketenophiles. Chloro-, dichloro- and diphenylketenes reacted with 1-methoxy-3-trimethylsiloxy-l,3-butadiene, and 2,4-bis(trimethylsiloxy)-1,3-pentadiene to yield the corresponding dihydropyrans. The dihydropyrans yielded substituted 4-pyranones on hydrolysis.

An 8-Step Program: Shaping and Fixed-Time Food Delivery Effects on Several Approximations and Undesired Responses in Goats. (open access)

An 8-Step Program: Shaping and Fixed-Time Food Delivery Effects on Several Approximations and Undesired Responses in Goats.

This study investigated the effects of a shaping program for halter training across 8 steps in the program and 4 trial-terminating, or "undesirable," responses. Three La Mancha goats (Capra hircus) located at the Frank Buck Zoo in Gainesville, Texas were used for the study. A fixed-time 15 s (FT-15 s) was used during the baseline conditions, to examine the effects of response contingent and response-independent food deliveries, as well as to examine what preliminary steps might not necessarily have to be shaped. All 3 goats successfully learned to allow the halter to be placed on them and to lead on the halter, although 2 of the 3 goats required an additional task analysis for the fifth step to further break down that approximation. Several of the early steps selected by the researchers were not necessary to complete the program, as determined by the baseline condition.

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress (open access)

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress

The activity of plant 9-lipoxygenases (LOXs) influences the outcome of Arabidopsis thaliana interaction with pathogen and insects. Evidence provided here indicates that in Arabidopsis, 9-LOXs facilitate infestation by Myzus persicae, commonly known as the green peach aphid (GPA), a sap-sucking insect, and infection by the fungal pathogen Fusarium graminearum. in comparison to the wild-type plant, lox5 mutants, which are deficient in a 9-lipoxygenase, GPA population was smaller and the insect spent less time feeding from sieve elements and xylem, thus resulting in reduced water content and fecundity of GPA. LOX5 expression is induced rapidly in roots of GPA-infested plants. This increase in LOX5 expression is paralleled by an increase in LOX5-synthesized oxylipins in the root and petiole exudates of GPA-infested plants. Micrografting experiments demonstrated that GPA population size was smaller on plants in which the roots were of the lox5 mutant genotype. Exogenous treatment of lox5 mutant roots with 9-hydroxyoctadecanoic acid restored water content and population size of GPA on lox5 mutants. Together, these results suggest that LOX5 genotype in roots is critical for facilitating insect infestation of Arabidopsis. in Arabidopsis, 9-LOX function is also required for facilitating infection by F. graminearum, which is a leading cause of Fusarium head …

12 Études Caractéristiques, Opus 2, by Adolf von Henselt: A Pedagogical Guide with Practical Exercises on Selected Etudes (open access)

12 Études Caractéristiques, Opus 2, by Adolf von Henselt: A Pedagogical Guide with Practical Exercises on Selected Etudes

Adolf von Henselt (1814–1889) was one of the most renowned German pianists and composers of his day. The majority of his compositions are for the piano, one of his most successful being the set of Piano Études, Op. 2. It consists of twelve etudes, each of which is designed for developing a particular technique. Henselt's etudes are as demanding as Chopin's and Liszt's, so this pedagogical guide is designed for advanced-level students. Henselt uses many finger extensions and stretches larger than an octave, which may be difficult for smaller hands to play, but proper flexibility and relaxation should enable all students to play them. This dissertation describes the specific technique for six selected etudes and provides exercises to help students learn each technique effectively. The selected etudes—Nos. 1, 2, 3, 6, 9, and 11—were chosen to cover all three technical levels of less-advanced, advanced, and very advanced as well as a variety of musical styles and technical challenges.

"The '91 Roos"

The ‘91 Roos is a sports documentary focused in Killeen, Texas. exploring the 1991 Killeen Kangaroos high school football team and their journey to their city's one and only state championship in football. Killeen is a small central Texas town that is directly adjacent and provides support to Ft Hood, one of the world's largest military bases. With the Persian Gulf War raging in 1991, soldiers that lived in Killeen were being sent off to fight, leaving the city almost like a ghost town. In October 1991, the Luby's Massacre occurred in Killeen, bringing the already depleted city further down by tragedy. At the time, this was the worst mass shooting in US history. This high school football team went on a fairy tale type of run during their 1991 season, resulting in winning a state title and bringing big hope back to a small town in need. Using direct interviews, narration and archival footage, this film provides an emotional yet inspirational look at a small town football team and their improbable season.

161 Glass: Site Specific Music in an Artistic Context (open access)

161 Glass: Site Specific Music in an Artistic Context

The composition 161 Glass is a 17-minute musical work with percussion, wind and brass instruments in which the intersection of mid-century architecture, and the art and culture of a dynamic city are inextricably linked. Through this paper, I explore the process of composing a musical work in relationship to the significance of site specific context. The paper begins by defining the concept of site specific art works; then reviews the discourse of the intersection of art, music and architecture. I then delve into the cultural and geographic context surrounding this project from the modern era through the present, and how those perspectives apply to the building and my piece. I reveal how the composition relates the musical ideas to the site. Finally, I describe the collaborative process between myself, the musicians and the Dallas Contemporary staff.

A 018μm Cmos Transmitter for Ecg Signals

Electrocardiography (ECG) signal transmitter is the device used to transmit the electrical signals of the heart to the remote machine. These electrical signals are ECG signals caused due to electrical activities in the heart. ECG signals have very low amplitude and frequency; hence amplification of the signals is needed to strengthen the signal. Conversion of the amplified signal into digital information and transmitting that information without losing any data is the key. This information is further used in monitoring the heart.

The 1896 Vienna Tonkünstler-verein Competition: the Three Award-winning Works and Seven Anonymous Submissions with Clarinet (open access)

The 1896 Vienna Tonkünstler-verein Competition: the Three Award-winning Works and Seven Anonymous Submissions with Clarinet

The Vienna Tonkünstler-Verein (1885-1929) was established for the sole purpose of providing extensive support to the music and musicians of Vienna. The society became renowned in Vienna for its outstanding performances of chamber music and counted among its members many of the city’s foremost musicians and composers. Johannes Brahms had a significant influence on the society as its honorary president and assisted in establishing its composition competitions, aimed at promoting and reviving under-developed chamber genres. Of particular interest to clarinetists is the Verein’s competition of 1896, which aspired to promote chamber music literature for wind instruments. Brahms’s recently completed chamber works for clarinet were clearly influential in fin-de-siècle Vienna; for of the twelve works chosen as finalists in the competition, ten included the clarinet in the chamber combination.The purpose of this document is to provide an English-language history of the Vienna Tonkünstler-Verein and a thorough account of its1896 competition based on my study of the society’s annual reports. In addition, this document will provide the first published account of the anonymous submissions for the 1896 competition. It is my hope that this paper will serve as a springboard for future endeavors aimed at uncovering the identities of the anonymous finalists …

The 1948 States' Rights Democratic Movement in Texas (open access)

The 1948 States' Rights Democratic Movement in Texas

The purpose of this paper is to examine, from a local perspective, the reaction of the southern conservative wing of the Democratic party to the liberal changes which occurred in that organization as a result of the transitional decades of the 1930s and 1940s. In particular, the study focuses on the growing sense of alienation and the eventual withdrawal of a handful of Texas Democrats from affiliation with the national body and their subsequent realignment with other dissident Dixie Democrats in the short-lived States' Rights party of 1948. This work is based essentially on the personal recollections of Texans who participated in the States' Rights movement and on those papers of the party's leaders which have survived until today.

1972 Presidential Campaign Investigation Based on Attitude Measurements of Candidate Images

The relationship of attitude measurement with the political campaign process provides the problem area that this study considers. The purpose of this political communication study is to explore in detail and describe various "attitude" profiles of voters and resulting candidate "images" of the 1972 presidential election. These "attitudes" and "images" are determined through the use of three primary research instruments: the semantic differential scale, the Method of Ordered Alternatives, and the political philosophy continuum. In addition to these, a record of actual voting behavior serves as validating support of the measured attitudes. This study deals with "attitudes" toward and candidate "images" of George McGovern, R. Sargent Shriver, Richard M. Nixon, and Spiro T. Agnew, the Democratic and Republican candidates for President and Vice-President in 1972. This descriptive investigation unfolds into three major problem areas: 1. to report and describe "panoramic images" of Nixon,. McGovern, Agnew, and Shriver, as measured by the semantic differential scale. 2. to give an account of voter preferred positions A through I as measured by the Method of Ordered Alternatives in connection with "attitude" as measured by the evaluative factor of the semantic differential scale, and subsequently aligned with actual voting behavior. 3. to determine the …
