abstract: Pregnancy and childbirth are both natural occurring events, but still little is known about the signaling mechanisms that induce contractions. Throughout the world, premature labor occurs in 12% of all pregnancies with 36% of infant deaths resulting from preterm related causes. Even though the cause of preterm labor can vary, understanding alternative signaling pathways, which affect muscle contraction, could provide additional treatment options in stopping premature labor. The uterus is composed of smooth muscle, which is innervated, with a plexus of nerves that cover the muscle fibers. Smooth muscle can be stimulated or modulated by many sources such as neurotransmitters [i.e. dopamine], hormones [i.e. estrogen], peptides [i.e. oxytocin] and amines. This study focuses on the biogenic monoamine tyramine, which is produced in the tyrosine catecholamine biosynthesis pathway. Tyramine is known to be associated with peripheral vasoconstriction, increased cardiac output, increased respiration, elevated blood glucose and the release of norepinephrine. This research has found tyramine, and its specific receptor TAAR1, to be localized within mouse uterus and that this monoamine can induce uterine contractions at levels similar to oxytocin. / Dissertation/Thesis / Masters Thesis Biology 2017

This thesis is an historical, thechnical dn stylistic investigation of Mozart horn concertos. It includes a description of Mozart's life; the moment in his life where the concertos were developed. It contains information about Inaz Leitgeb, the horn player who has a close friendship with Mozart. Also, the explanation of his technical characteristics of the natural horn and the way of Mozart deal with the resources and limis instrument, as well as the way of the interpretation of these pieces had beed facilitated by the arrival of the chromatic horn. I found out that the knowledge of these concertos is essential for their interpreation.

The purpose of this manuscript is to provide a representative collection of jazz standards with improvised solos fashioned after the types of resources available for traditional jazz instruments, yet transcribed and adapted specifically for horn, hence, expressly designed to assist horn players in achieving greater success in jazz performance. By providing transcriptions and adaptations of significant performances from jazz history, horn players will have a resource with which they can better understand jazz performance practice. Featured artists include Miles Davis, Curtis Fuller, Ella Fitzgerald, Tommy Turk, Charlie Parker, Sonny Rollins, John Coltrane, Miles Davis, Wes Montgomery, J. J. Johnson, Stan Getz, and Milt Jackson. Song titles and albums are as follows: "Autumn Leaves," Somethin' Else (1958), "Blue Train," Blue Train (1957), "How High the Moon," Ella in Berlin (1960), "Lester Leaps In," Jazz at the Philharmonic (1949), "Lover Man," The Magnificent Charlie Parker (1951), "Moritat," Saxophone Colossus (1956), "Naima," Giant Steps (1959), "On Green Dolphin Street," Kind of Blue (1959), "Polka Dots and Moonbeams," Jazz Guitar of Wes Montgomery (1960), "Satin Doll," The Trombone Master (1957), "Stella by Starlight," Stan Getz Plays (1952), "Straight, No Chaser," Genius of Modern Music 2 (1951).

Helen Kotas was an accomplished musician and teacher who helped open the door for women in major US orchestras. In 1941 the Chicago Symphony hired its first female brass musician, principal hornist Helen Kotas. With that daring move, she became a pioneer for her gender in the major orchestras of North America. Despite her many contributions to the musical community, Kotas's life has not been researched and documented. This paper looks at Helen Kotas's career as well as a glimpse at her life and personality. In addition to documenting her life, this dissertation attempts to show at least a portion of Kotas's philosophy of teaching and horn playing. She was an accomplished horn soloist and studied the literature extensively. Kotas performed in the Chicago Civic Orchestra, the Woman's Symphony Orchestra, and Leopold Stokowski's All-American Youth Orchestra. Kotas was hired by Fritz Reiner as third horn of the Pittsburgh Symphony. When Frederick Stock, conductor of the Chicago Symphony Orchestra, heard that Helen Kotas was going to Pittsburgh, he insisted that she audition for the CSO. Kotas auditioned on the Concerto for Horn by Richard Strauss and the concertmaster said, "Hire her!" She performed as principal horn with the orchestra until Artur Rodzinski was hired as conductor in 1948 and replaced Kotas with Philip Farkas. Following her time with the CSO, Kotas was principal horn of the Chicago Lyric Opera and taught at the Sherwood and American Conservatories. She was an active soloist and premiered works by Arne Oldberg and Hugo Kauder.

While the word “pedagogue” may evoke a vision of an instructor who is dogmatic and set in his own ways, the word descends from Greek origins: ped “child” + agogos “leader.” A pedagogue is, by definition, literally the servant who escorts the child to and from school – the “pedagogue” accompanies the student on the journey for knowledge. True to this definition, Douglas Campbell is model pedagogue – one who gently guided his countless students throughout their musical journeys. As Professor of Music (Horn) at Michigan State University for 45 years, and Horn Instructor at Interlochen Arts Camp for 25 years, Campbell was a significant influence on many developing hornists. Following their study with him, Campbell's students eventually won orchestral and college teaching positions across the United States and throughout the world. Having influenced an extraordinary number of horn students during his tenures at Michigan State University and Interlochen Arts Camp, Douglas Campbell's life and career serve as an excellent example of contemporary horn pedagogy in the United States. This dissertation provides a detailed biography of Douglas Campbell and provides evidence of his contributions to American horn pedagogy, while documenting Campbell’s performing career with the Richards Quintet, which toured the United States, Canada, and China. Additionally, compositions written for or commissioned by Campbell (Harmonielehre: Variations for Solo Horn [1996] and Epitaph [2012]) are discussed, to illustrate Campbell's influence on solo literature for the horn.

Yes / The Helpdesk was requested by Sida in July 2015 to undertake a desk study and mapping exercise to feed in relevant and updated information related to policy frameworks, ongoing programming, and future initiatives currently discussed to better inform Sida’s planned and on-going resilience focus. Sida requested that the study should pay particular attention to regional initiatives (including for example relevant IGAD initiatives), but should also include a mapping of relevant policy platforms, as well as planned and on-going programmes relevant for the Ethiopia, Kenya, Somalia and South Sudan country contexts.

Yes / In this paper, a conical horn antenna has been designed for Ultra-Wideband ap-plications by loading its section with a metamaterial. The work aims first to compare results obtained by the wavelet-moment method to a simulation performed using HFSS. Secondly the conical horn is loaded with a very thin layer of metamaterial to enhance the radiation pattern and the bandwidth performance of the conical horn antenna and reduce the size of the antenna. The operating bandwidth of the proposed antenna is in the range of 10{13 GHz. The results obtained from HFSS and moment method are in good agreement. / Electronics and Telecommunications

The purpose of this study is to trace the development of a practically extinct woodwind instrument, the basset horn, and its use by composers as both a solo and an orchestral instrument. The first chapter concerns the development of the basset horn from the earliest imperfect specimen to the modern-day instrument. The second chapter deals with the physical characteristics that are peculiar to the instrument. The third chapter discusses the literature and musical history of the basset horn. An appendix provides a comprehensive listing of literature for the instrument.
