Expressions of Madness in Coloratura Mad Scenes of Bel Canto Operas
This thesis will explore the musical innovations in the mad scenes of the bel canto composers in the 1800s. It will analyze Gaetano Donizetti’s mad scenes in Anna Bolena (1830) and Lucia di Lammermoor (1835), and Vincezzo Bellini’s mad scenes in I Puritani (1835) to discover how each composer expresses madness through the high and virtuosic voice of the coloratura soprano. The subject of madness is not a new idea in opera. However, the mad scenes of Donizetti and Bellini are the most successful and are often performed in opera houses around the world. Specific attention is given to the vocal melodies and passages of coloratura which are used to express the various emotions of the character in the midst of her madness. Between 1830 and 1835, the madness of the characters becomes increasingly extreme, culminating in the shocking and thrilling moment in Lucia di Lammermoor when Lucia appears on the stage in a blood stained nightgown. She has gone insane and has murdered her husband. Through the musical genius of Donizetti and Bellini and the vocal prowess of great impresarios, some of the greatest meltdowns of all time are played out on the operatic stage
A New Weapon - A New Monster - The Walkout : The East Los Angeles Student Walkouts of 1968
In March of 1968, East Los Angeles witnessed thousands of Mexican American students walk out of Belmont, Garfield, Lincoln, Roosevelt, and Wilson High Schools. In what became known as the East Los Angeles Blowouts, the protests sparked a series of walkouts from high schoolers nationwide. The students protested what I call “educational racism.” This term refers to different ways the education system in East Los Angeles discriminated against Mexican Americans students on the basis of their race. This Independent Study analyzes how the students in East Los Angeles embraced their identity as both students and Mexican Americans to protest against the educational racism in their schools. By placing the students’ actions into a theoretical framework known as the “Movement Culture,” and using the concept of a “free space,” this study shows how the Mexican American students’ organizing, heightened political consciousness, execution of a massive protest, and the aftermath of the walkout led to a new specific student movement within the Chicano Movement as a whole
Genesis of Gold Mineralization in the Lone Jack Mine Area, Mt. Baker Mining District, Washington
The Lone Jack group of claims is in the Mt. Baker Mining District, northern Whatcom County, Washington. Three prominent gold-quartz veins are present, two of which were mined and produced 945 kg of gold between 1901 and 1924. Since then mining operations have not been renewed.
The quartz veins are within 3 km of surface exposures of the Miocene Chilliwack Batholith, above and within a zone of deformation related to the mid-Late Cretaceous Shuksan fault. This major Northern Cascades structure has juxtaposed the Upper Mesozoic Carrington Phyl lite over the Paleozoic volcanic and sedimentary rocks of the Chilliwack Group. The quartz veins are genetically related to local Tertiary block faulting which postdated the metamorphism and deformation related to the Shuksan fault. The style of deformation and timing of these Tertiary faults suggests that they are related to the emplacement of the nearby batholith. The quartz veins were emplaced during, perhaps in the waning stages of, this intrusive activity.
Two generations of mineralization are present; each has a similar paragenesis. Vein minerals other than quartz include pyrrhotite, pyrite, chalcopyrite, tellurbismuth, and free gold. Gold was deposited in equilibrium with pyrrhotite, sericite, and graphite.
Fluid inclusion analyses were used to determine that the ore-forming solutions were boiling, dilute, and contained an average of 0.25 mol% CO2. Crystallization occurred at about 285oC and 625 bars of lithostatic pressure. Thermodynamic calculations indicate that the gold may have been transported as the Au(HS)ˉ2 complex, and that precipitation of the gold resulted from the physiochemical changes caused by boiling.
Prospecting for similar deposits in the area should be directed toward locating post-metamorphic quartz veins near the Shuksan fault and the Chilliwack Batholith, which show evidence of boiling
The final measurement of by NA48
The direct CP violation parameter Re() has been measured
from the decay rates of neutral kaons into two pions using the NA48 detector at
the CERN SPS. The 2001 running period was devoted to collecting additional data
under varied conditions compared to earlier years (1997-99). The 2001 data
yield the result: Re()=.
Combining this result with that published from the 1997,98 and 99 data, an
overall value of Re()= is
obtained from the NA48 experiment.Comment: 5 pages, 3 figures. Proceedings for the ICHEP02 conferenc
Phenomenon of the time-reversal-violating photon polarization plane rotation by a gas placed to an electric field
T-odd P-odd phenomenon of the photon polarization plane rotation (circular
dichroism) is considered for an atomic (molecules) gas placed to an electric
field. The expression for the T non-invariant polarizability of an atom
(molecule) placed to an electric field is obtained. It is shown that the T-odd
plane rotation angle increases when the interaction energy of an atom
(molecule) with an electric field is the same order as the opposite parity
levels spacing.Comment: 9 pages, Late
Bulletin No. 201 - Economic Insects in Some Streams of Northern Utah
The food of trout in our mountain streams is mainly insects. It is, in part, land insects that fall on the water and are taken as they float upon its surface, but in a much larger part it is insects that grow up in the water and are taken in their immature stages. These are the constant and dependable food-supply. They have been little studied hitherto. This bulletin is a report of a preliminary examination of some Utah streams, made for the purpose of discovering what forms of life are present in the streams and in what relative abundance. Some are beneficial and some injurious to trout, being competitors with them for food
Quenching of lamellar ordering in an n-alkane embedded in nanopores
We present an X-ray diffraction study of the normale alkane nonadecane
C_{19}H_{40} embedded in nanoporous Vycor glass. The confined molecular crystal
accomplishes a close-packed structure by alignment of the rod-like molecules
parallel to the pore axis while sacrificing one basic principle known from the
bulk state, i.e. the lamellar ordering of the molecules. Despite this disorder,
the phase transitions observed in the confined solid mimic the phase behavior
of the 3D unconfined crystal, though enriched by the appearance of a true
rotator phase known only from longer alkane chains.Comment: 7 pages, 3 figure
Molecular Cloning and Endometrial Expression of Porcine Amphiregulin
The porcine amphiregulin gene was previously reported to be within the quantitative trait locus (QTL) for uterine capacity on chromosome 8. Because amphiregulin stimulates cell proliferation, the amphiregulin gene might be responsible for this QTL. The objectives of this study were to clone amphiregulin cDNA and compare endometrial expression of its mRNA in pregnant Meishan (M) and White composite (WC) pigs. We obtained two amphiregulin cDNAs, one with 1,221 bp and another with 1,109 bp. The 112 bp difference corresponded to exon 5 of the human amphiregulin gene, which codes for the cytoplasmic domain. Endometrial mRNA expression of amphiregulin was significantly lower in M pigs than in WC pigs during early pregnancy (day 15–40 of gestation). Amphiregulin mRNA expression in the endometrium of both M and WC pigs increased (P \u3c 0.01) from days 15 to 20, decreased (P \u3c 0.01) from days 20 to 30, and did not change between days 30 and 40. This may result in reduced amphiregulin protein production leading to the slower development of M conceptuses, contributing to greater uterine capacity and litter size in prolific Chinese M pigs. Porcine genomic sequences isolated from a bacterial artificial chromosome genomic library contained exon 5, suggesting that the deletion of exon 5 in the mRNA may be due to differential splicing. The amphiregulin gene consisted of six exons and five introns spanning 10.3 kb
Lack of Effect of Metyrapone and Exogenous Cortisol on Early Porcine Conceptus Development
In many species, including swine, fetal plasma glucocorticoids such as cortisol increase as term approaches and are responsible for final maturational changes in numerous tissues (e.g. Silver, 1990; Sangild et al. 1993, 1994; Fowden et al. 1995). On the contrary, excessive exposure to glucocorticoids during gestationmay cause intra-uterine growth retardation, developmental abnormalities or death, or lead to increased incidence of certain diseases during adult life (Blackburn et al. 1965; Reinisch et al. 1978; Seckl et al. 2000). Hence, one might speculate that a closely regulated glucocorticoid exposure is necessary throughout gestation to ensure appropriate development and survival (Klemcke et al. 1999). We have previously demonstrated in pregnant and cyclic pigs that intra-uterine cortisol increases 4- to 6.7-fold between days 10 and 19 of pregnancy (Klemcke et al. 1998). At this time (days 10–19) in conceptus (embryo plus associated extra-embryonic membranes) development, the blastocyst is undergoing quite dramatic changes (Marrable, 1971; Anderson, 1978; Anderson et al. 1993). Part of this development involves the allantois, which rapidly expands between days 18 and 30 owing to water accumulation (Bazer et al. 1981) that might in part result from Na+,K+-ATPase-generated water movement (Macknight & Leaf, 1977). Corticosteroids are known to regulate Na+,K+-ATPase in various tissues (e.g. Verrey et al. 1996)
