The thesis is a traditional piano quintet in the manner of Bartok, incorporating compositional techniques such as golden ratio and using folk materials. Special effects on strings are limited for easy conversion to wind instruments. The piece is about 15 minutes long.

Pyrmnesium parvum, commonly known as golden algae, is an algal species that under certain circumstances releases toxins which can lead to fish kills and the death of other economically and ecologically important organisms. One of the major objectives of the study was to investigate whether a relationship exists between land use and Prymnesium parvum abundance in littoral sites of Lake Texoma, USA. Another objective was to investigate whether a relationship exists between other physical variables and counts of P. parvum. Lastly, developing a valid model that predicts P. parvum abundance was an objective of the study. Through stepwise regression, a small but highly significant amount of the variation in P. parvum counts was found to be explained by wetlands, soil erodibility and lake elevation. The developed model provides insight for potential golden algae management plans, such as maintaining wetlands and teaching land owners the relationship between soil erosivity and golden algae blooms.

Thesis advisor: Stephen Brown / Although hagiography and sermons from the Middle Ages are abundant, little research exists that explores the relationship between these two genres. Jacobus de Voragine compiled the most renowned medieval collection of hagiography, Legenda aurea (Golden Legend). He also compiled several volumes of model sermons, including a volume on the saints, sermones de sanctis. This dissertation examines four saints who appear in both of these works: Mary Magdalene, Benedict, Nicholas and Peter Martyr. By writing his hagiography and sermons, Jacobus attempted to guide Christians toward lives of virtue and ultimate union with God. In particular, Jacobus relied on tropological and anagogical reading of Scriptures in order to communicate how Christians should behave and what they should anticipate in eternity. In his work on two of these saints, Mary Magdalene and Benedict, Jacobus relied on the framework of spiritual ascent to God described by Pseudo-Dionysius. In particular, Jacobus focused on the first stage of ascent, the purgative. A link between the hagiography and sermons sometimes can be found in the etymological introductions in the Golden Legend. In the sermons on Mary Magdalene and Peter Martyr, Jacobus follows the virtues found in the etymology in the hagiography, while for Nicholas and Benedict, the correspondence is not as faithful. Nevertheless, throughout his sermons on the saints, Jacobus refers to episodes described more fully in the Golden Legend. Jacobus intended preachers to use stories from the Golden Legend to punctuate and illustrate the more theological content presented in the model sermons. If Jacobus's work is indicative of larger trends in medieval preaching, preachers expected to utilize hagiographical resources in order to urge their listeners to the virtuous life and an eschatological union with God. / Thesis (PhD) — Boston College, 2010. / Submitted to: Boston College.

Thesis advisor: David Gill / The idea that mankind's history is one of regress rather than of progress has been seen as central to the classical outlook on life. Bury and others have gone so far as to state that the idea of Progress in its modern sense could not have even occurred to the Greeks. This is perhaps too extreme, but it does reflect an important point: if regression over time was not the only idea for the Greeks, it was at least the dominant one. No story in classical literature reflects this idea more clearly than the Myth of the Ages. The earliest extant version of the story comes in Hesiod's Works and Days (c. 700 B.C.), after which it appears dozens of times throughout ancient literature. The myth in its standard form tells that the history of mankind takes the form of four ages, each represented by a metal: the first is a happy and virtuous Golden Age; the next is a less perfect Silver Age, followed by a warlike (and even worse) Bronze Age; and the last, the most impious and wretched of all, is the current Iron Age. The early Hesiodic version uses this framework merely as a means to show man that he has fallen from divine favor and is left with a life of hardship that he must deal with through honest work and reverence for the gods. As other authors pick up the myth, alluding to it in genres as diverse as philosophy, theology, humor, and panegyric, the story changes in several ways. Each author of course uses it for his own purposes and alters it accordingly. In addition the Myth of the Ages undergoes an overall change: after Hesiod authors such as Aratus, Ovid, Seneca, and Maximus use the myth as a means to pair material progress with moral regression. These authors do not merely tell a story; they present a model, a simple and pre-civilized way of living that they see as vastly superior to modern “advanced” society. These authors look at the results of technological progress and see only negatives; for them the ship and the sword have brought nothing but greed and violence. They present a simple and virtuous Golden Age that lacks the fruits of civilization and a wretched and bloodied Iron Age that is flooded by them. The implication is clear: mankind has fallen from a life of primeval bliss at its own hands as a direct result of technological and societal advances. This becomes the dominant message of the Myth of the Ages, so much so that by the time of the Romans the myth had become little more than a literary cliché for criticizing civilization. / Thesis (BA) — Boston College, 2004. / Submitted to: Boston College.

Blood flow velocity was measured by a modification of the technique described by Hugues (Arch. Int. de Physiol. 61: 565, 1953). Internal vessel diameters and widths of the total peripheral plasma layer were measured with an ocular micrometer. Thrombus thresholds were determined by graded electrical stimulation. Determinations were made on 202 vessels in retrolingual membranes of frogs prepared by single pithing. In 95 arterioles (diameters from 10 to 40 microns), the mean flow velocity was 2.84 mm/sec. and the mean volume flow rate, 1.68xl0-3 cu mm/sec. The mean width of the total peripheral plasma layer was 3.6 microns and its ratio to mean vessel diameter was 1:6. In 107 venules (diameters from 10 to 50 microns), the mean flow rate was 1.20 mm/sec. The mean volume flow rate was 1.02x10-3 cu mm/sec. The mean width of the total peripheral plasma layer was 4.1 microns and its ratio to mean vessel diameter was 1:7.4. The ratios of mean arterial to mean venous velocity and volume flow were 1:2.3 and 1:1.6 respectively. Measurements were made on 100 mesenteric vessels of frogs prepared by single pithing. In 50 arterioles (diameters from 15 to 45 microns), the mean velocity was 3.77 mm/sec. The mean volume flow was 3.05xlo-3 cu mm/sec. The mean width of the total peripheral plasma layer was 2. 7 microns and its ratio to mean vessel diameter was 1:11.5. In 50 venules (diameters from 20 to 50 microns), the mean velocity was 1.55 mm/sec. and the mean volume flow rate, 1.76x10-3 cu mm/sec. The mean width of the total peripheral plasma layer was 6.7 microns and its ratio to mean vessel diameter was 1:5.3. The ratios of mean arterial to mean venous velocity and volume flow were 1:2.3 and 1:1.7 respectively. A total of 109 mesenteric vessels were studied in frogs anesthetized with urethane. In 55 arterioles (diameters from 15 to 45 microns), the mean velocity was 3.28 mm/sec. The mean volume flow was 2.87x10-3 cu mm/sec. The mean width of the total peripheral plasma layer was 3.2 microns and its ratio to mean vessel diameter was 1:9.3. In 54 venules (diameters from 20 to 50 microns), the mean flow rate was 1.61 mm/sec. and the mean volume flow, 1.83x10-3 cu mm/sec. The mean width of the total peripheral plasma layer was 5.6 microns and its ratio to mean vessel diameter was 1:5.9. The ratios of mean arterial to mean venous velocity and volume flow were 1:2.0 and 1:1.5 respectively. In these three series of studies in the frog, no relationship was clearly apparent between velocity and either vessel diameter or width of the peripheral plasma layer in arterioles. Suggestions of a direct relationship between velocity and peripheral plasma layer in veins, however, were evident. In all cases, and in both arterioles and venules, vessel diameter and peripheral plasma layer were clearly and directly related. The effects of flow velocity changes on width of the total peripheral plasma layer in individual vessels were studied in 26 arterioles of the hamster cheek pouch. Blood flow was varied by means of a cuff described by Copley (Biorheology 1: 3, 1962). A direct relationship between velocity and width of the peripheral plasma layer was clearly demonstrated. Thrombus thresholds were determined in mesenteric vessels of the frog. In 103 arterioles (diameters from 20 to 140 microns), the mean strength of stimulus necessary to produce a platelet thrombus was 24.8 volts with an amperage of 0.18 milliamperes. In 100 venules (diameters from 20 to 140 microns), the mean strength of stimulus necessary was 20.7 volts with an amperage of 0.12 milliamperes. Possible relationships of thrombus thresholds to flow velocity in mesenteric arterioles and venules are discussed. / 2031-01-01

O presente trabalho irá abordar dois temas matemáticos de diferentes contextos históricos mas que apresentam uma relação intrínseca com o número Φ, mais conhecido como número de ouro. Partiremos de uma breve descrição dos conjuntos numéricos N, Z, Q e algumas propriedades dos números racionais para, em seguida, deduzirmos os números irracionais Π e, enfim, os números reais R. Na sequência vamos trabalhar com dois problemas muito antigos: o primeiro aparece na coletânea de livros Os Elementos do matemático grego Euclides, 300 anos a.C., e diz respeito à divisão de um segmento em média e extrema razão e, o segundo, foi publicado no livro Liber Abaci do matemático italiano Leonardo Fibonacci, século XIII, e trata da reprodução de coelhos e a sequência a qual ela origina. Veremos que o número de ouro aparece em ambos os problemas e vem ao longo dos séculos desencadeando muitas teorias que tratam de padrões e beleza. Abordaremos situações do passado e do presente que fazem uso desses padrões, além de fenômenos da natureza. Também apresentaremos um conjunto de atividades para orientar professores do ensino médio de como trabalhar, numa perspectiva interdisciplinar com vários conteúdos da matemática, e o número Φ. / This work addresses two mathematical topics from different historical contexts but that have an intrinsic relationship with the number Φ, better known as the golden number. We start with a brief description of the numerical sets N, Z, Q and some properties of rational numbers, and then deduct the set of irrational numbers π and, finally, the set of real numbers R. In the sequence we work with two very old problems: the first appears in the collection of books The elements of the Greek mathematician Euclid, 300 years BC, and concerns the division of a segment in extreme and mean ratio, and the second, published in the book Liber Abaci of the Italian mathematician Leonardo Fibonacci, in the thirteenth century, and deals with the breeding of rabbits and the sequence which it originates. We will see that the golden number appears on both problems and has over the centuries triggering many theories dealing with standards and beauty. We discuss situations of past and present that makes use of these standards, as well as natural phenomena. We also present a set of activities to guide middle school teachers on how to work in an interdisciplinary perspective with various mathematical content, and the number Φ.

Entre los grandes autores de teatro del siglo XVII se puede encontrar a Francisco de Leiva Ramírez de Arellano. El siglo en el que vivió es uno de suma importancia en el mundo del teatro, ya que los escritores del momento crearon cánones estilísticos que cambiaron la forma de escribir estas obras para siempre. De Leiva, que fue seguidor de la escuela de Calderón, se conocen unas catorce obras de teatro y un entremés, y se sabe que sus obras no tuvieron mayor éxito hasta el siglo XVIII. En la modernidad su nombre es poco conocido y sus trabajos han sido escasamente publicados. Esta tesis intentará desenterrar una obra de Leiva, La dama presidente, para entender mejor el teatro español de su tiempo.
