Courting Death: 30 Years Since Furman, Is the Death Penalty Any Less Discriminatory? Looking at the Problem of Jury Discretion in Capital Sentencing
Heegaard genus, cut number, weak p-congruence, and quantum invariants
We use quantum invariants to define a 3-manifold invariant j_p which lies in
the non-negative integers. We relate j_p to the Heegard genus, and the cut
number. We show that j_$ is an invariant of weak p-congruence.Comment: to appear in JKTR. 8pages 1 figur
Distribution of the Water Scorpion \u3ci\u3eNepa Apiculata\u3c/i\u3e (Hemiptera: Nepidae) in Wisconsin
The water scorpion Nepa apiculata Uhler was considered rare in Wiscon- sin by Hilsenhoff (1984), who collected only 11 individuals during a 25-year period. All of his collections were from overwintering sites, especially debris in streams, during early spring or autumn (Hilsenhoff, pers. comm.). He concluded that the species was restricted to southern Wisconsin. Recent collections indicate that N. apiculata is more widely distributed. These records, summarized below, are documented with specimens in the University of Wisconsin-Madison insect collection
Loquit, ridet, et vincit : lâintĂ©gration du toscan dans la commedeja pe âmmuseca et sa mise en musique : une forme de rĂ©sistance contre la domination Ă©trangĂšre
La version intĂ©grale de ce mĂ©moire est disponible uniquement pour consultation individuelle Ă la BibliothĂšque de musique de lâUniversitĂ© de MontrĂ©al (www.bib.umontreal.ca/MU).Au dĂ©but du dix-huitiĂšme siĂšcle, un nouveau genre opĂ©ratique en « langue napolitaine » se dĂ©veloppe Ă Naples, la commedeja pe âmmuseca (« comĂ©die en musique »). Celui-ci intĂšgre peu Ă peu dans ses intrigues des personnages sâexprimant en toscan et accompagnĂ©s dâune musique inspirĂ©e du dramma per musica. Cette intĂ©gration de la langue littĂ©raire de la PĂ©ninsule et dâun style musical serio est interprĂ©tĂ©e comme une tentative dâennoblir le genre et a menĂ© Ă la thĂ©orisation dâune dichotomie entre sphĂšre sĂ©rieuse toscane et sphĂšre comique napolitaine. FondĂ©e sur une vision rĂ©ductrice de la situation linguistique napolitaine, associant le toscan aux nobles et le napolitain au peuple, cette conception ne reflĂšte ni la situation linguistique et politique de lâĂ©poque, ni la rĂ©alitĂ© des livrets et de leur mise en musique, comme ce mĂ©moire se propose de le dĂ©montrer. En effet, lâĂ©tude du contexte politique et linguistique dans lequel la commedeja sâest dĂ©veloppĂ© rĂ©vĂšle que le napolitain Ă©tait la langue usuelle du peuple et de lâaristocratie. De plus, Naples Ă©tait sous domination Ă©trangĂšre et le toscan Ă©tait la langue employĂ©e par les dominateurs: le napolitain devenait donc un symbole de napolĂ©tanĂ©itĂ© et du dĂ©sir dâautonomie des habitants du Royaume de Naples. Dans ce mĂ©moire, le dĂ©pouillement dâun corpus de soixante-six livrets datant de 1721 Ă 1749 et lâanalyse de lâopĂ©ra Lo frate ânnamorato (1732) de Gennaro Antonio Federico et Giovanni Battista Pergolesi suggĂšrent que lâintĂ©gration du toscan dans la commedeja incarne une forme de rĂ©sistance contre la domination Ă©trangĂšre.The commedeja pe âmmuseca, a comic operatic genre in Neapolitan, flourished in early eighteenth-century Naples. Gradually, it began integrating Tuscan-speaking characters into its plots, accompanied by a dramma per musica inspired musical style. This inclusion of the literary language of the Peninsula and of a seria musical style has been interpreted as an attempt to ennoble the genre, and has led to the theorization of a dichotomy between Tuscan serious characters and Neapolitan comic ones. This view of Tuscan is based on the mistaken premise that Neapolitan is the language of the people and Tuscan, that of the aristocracy. I argue that, caused by a misunderstanding of the political and linguistic context of eighteenth-century Naples, it not only overlooks the reality of the music and libretti, but also neglects the political and nationalistic dimensions of the genreâs multilingualism. In fact, Neapolitan was spoken by all Neapolitans, whereas Tuscan was the language of foreigners and of the Austrian ruling power. This leads me to suggest a new interpretation to the commedejaâs multilingualism: accompanied by regional characterization, it is actually a form of local resistance against foreign domination. The analysis of sixty-six libretti, dating from 1721 to 1749, and of Lo frate ânnamorato (1732) by Gennaro Antonio Federico and Giovanni Battista Pergolesi, confirm this hypothesis
The Deoxygenation and Hydrogenation Properties of Noble Metal-Based Bimetallic Phosphide Catalysts
With increasing concern regarding the environmental impacts of fossil fuels, and the difficulty of extracting petroleum feedstocks, alternative liquid fuels are becoming more desirable. Bio-oil, which is oil derived from biomass, is a renewable source of liquid fuels. However, the high oxygen and water content of bio-oil results in high corrosivity and low energy density, making it unusable in the current liquid fuel infrastructure. The process of removing heteroatom impurities from oil is known as hydrotreating. Current hydrotreating catalysts are optimized for refinement of petroleum, and are not suitable for bio-oil deoxygenation. Transition metal phosphides (such as Ru2P) are a class of materials that have garnered interest recently for their unique electronic, magnetic, and catalytic properties. Several metal-rich phosphide phases have also demonstrated promising hydrotreating activity and resistance to deactivation compared to noble metal catalysts. Some bimetallic phosphide phases have been shown to possess even greater activity than their monometallic counterparts due to synergistic effects between the constituent metals.
A series of CoxRu2-xP (0 †X †2) and CoxRh2-xP (0 †X †2) catalysts supported on silica (SiO2) were prepared via impregnation followed by temperature programmed reduction (TPR). The furan and crotonaldehyde deoxygenation properties of the CoxRu2-xP/SiO2 catalysts were investigated and it was observed that the Co-rich catalysts possessed a higher activity than the Ru-rich catalysts with selectivity towards decarbonylation pathways and the production of C3 hydrocarbons. The CoxRu2-xP/SiO2 series showed no deactivation over 48 h in an 8 mol% furan/H2 feed at 578 K. The crotonaldehyde deoxygenation properties of the CoxRh2-xP/SiO2 were also investigated, and found to be more active than the CoxRu2-xP/SiO2 catalysts, with the Rh-rich catalysts possessing greater crotonaldehyde conversions than the Co-rich catalysts
