The trumpet as a musical and dramatic element in selected operas of Gioachino Rossini and Giuseppe Verdi: Its employment in on-stage and off-stage instrumental ensembles, a lecture recital, together with three recitals of selected works of J. G. B. Neruda, P. Hindemith, G. Antheil and others (open access)

The trumpet as a musical and dramatic element in selected operas of Gioachino Rossini and Giuseppe Verdi: Its employment in on-stage and off-stage instrumental ensembles, a lecture recital, together with three recitals of selected works of J. G. B. Neruda, P. Hindemith, G. Antheil and others

The popularity of the miscellaneous wind bands in Italian society through the centuries, and the prominent use of the trumpet within these ensembles and as a solo instrument, become evident in the examination of the development of the banda sul palco (the band on stage) in Italian opera. Gioachino Rossini was the first to use the banda sul palco (stage band) with any regularity. Giovanni Paisiello, Giuseppe Gazzaniga, and Wolfgang Amadeus Mozart must be considered earlier contributors to the growing movement of using instrumental ensembles on stage.

Genomic imprinting: support for the concept from a study of Prader-Willi Syndrome patients

In this study, nineteen cases of suspected or clinically diagnosed Prader-Willi Syndrome (PWS) were tested for molecular deletions by in situ hybridization with two DNA probes, IR4-3R and GABRB3. Both probes are specific for sequences within the chromosome region 15q11-13, with IR4-3R located within the putative PWS region and GABRB3 in the distal area associated with Angelman Syndrome.

An Analysis of Adding Land Cover as a Variable to the DRASTIC Ground Water Model

This study involved a geographic information systems (GIS) approach to modeling ground water pollution potential in the Southern Edwards Aquifer Region in Texas. The DRASTIC ground water model was analyzed using two methods. First, the effects of adding land cover data to the drastic model were evaluated. In the second approach, the effects of the removal of DRASTIC variables were evaluated. Six, five, and four variable models were generated and analyzed.

Evidence for a Role of the Multifunctional Calcium/Calmodulin-Dependent Protein Kinase II in Insulin Secretion (open access)

Evidence for a Role of the Multifunctional Calcium/Calmodulin-Dependent Protein Kinase II in Insulin Secretion

Calcium/calmodulin-dependent protein kinase II (CaM kinase II) is demonstrated to exist in the ß-cell and immunopecipitation. Glucose and potassium significantly stimulate the rapid autophosphorylation of CaM kinase II and proportionally induce autonomous activity of the kinase in a dose-dependent manner that parallels insulin secretion. The activation of CaM kinase II, alloxan, KN-62 and KN-93, suggest that the enzyme is an integral component of insulin secretion and/or related processes in the β-cell.

Synthesis, Purification and Pharacterization of Small Mono(ADP-Ribosyl)ated Molecules in the ADP-Ribose Elongation Reaction Catalyzed by Poly(ADP-ribose)Polymerase

The ADP-ribose elongation catalyzed by poly(ADP-ribose) polymerase (PARP) [EC 2.2.2.30] has been partially characterized utilizing mono (ADP-ribosyl)ated polyamines. Arginine methyl ester (AME)-(ADP-ribose) and agmatine (AGMT)-(ADP-ribose) were synthesized enzymatically with a eukarytic mono(ADP-ribosyl) transferase and cholera toxin, respectively.

The Canticles of Solomon (open access)

The Canticles of Solomon

The Canticles of Solomon , a musical drama written for tenor, mezzo soprano, chamber orchestra, and full chorus, is a three movement piece, 25 minutes in length. It is intended for performance without scenery, costume, or action. The fundamental element is text. The source text is The Song of Solomon from the Ryrie Study Bible. The text is cross referenced and used in the formal structure of the work. Each time a cross-referenced entry of text is reached, the melodic theme or rhythmic motive is found according to the appropriate theme category in which the specific text is placed. There are twelve theme categories. The melodic themes have differing levels of tonality. The formal structure is cyclically through-composed.

Creation and Characterization of an Escherichia Coli and Pseudomonas Putida Hybrid Aspartate Transcarbamoylase

Aspartate transcarbamoylase (ATCase) is encoded by the pyrBI genes in E. coli. Expression of these genes is reduced four-fold by attenuation when grown on uracil. Using plasmid, pRO1727. the pyrB and the pyrBI genes from E. coli were cloned into a P. putida pyrB auxotroph. A recombinant pyrB gene was recovered that encoded a functional hybrid ATCase with a molecular weight of 470 kDa.

Particle size distribution and qualitative/quantitative analysis of trace metals in the combustion gas and fly ash of coal/refuse derived fuel

This work includes two different areas of research. Both areas are related to the combustion of the binder-enhanced densified refuse derived fuel (bdRDF) with high sulfur coal and examining trace elements. The first area of this work involved studying the trace metals in the combustion gas of bdRDF/coal blend and the effect of the binder, CA(OH)2, on reducing the trace elements emissions. The second area of work involved studying the trace elements in the fly ash and the effect of the dRDF and the binder of trace metals.
