OVERTURE Love Love is a Pink Cake or Queering Chopin in Times of Homophobia

2021

An introduction to the three essays included in this section. The article highlights the right to know whether Chopin was gay and contextualizes this inquiry in a very long and pervasive historiographical tradition, essentially twohundred years long, dedicated to examine Chopin sexual orientation, on the one hand, and on the other the more recent tradition of queering western classical music composers. The main point is not to demonstrate categorically that Chopin was ?gay? (a relative, modern identity marker in any case) but rather to highlight the discourses that have presented him as unequivocally heterosexual.

Spectra and essential spectral radii of composition operators on weighted Banach spaces of analytic functions

2008

AbstractWe determine the spectra of composition operators acting on weighted Banach spaces Hv∞ of analytic functions on the unit disc defined for a radial weight v, when the symbol of the operator has a fixed point in the open unit disc. We also investigate in this case the growth rate of the Koenigs eigenfunction and its relation with the essential spectral radius of the composition operator.

Rescaling principle for isolated essential singularities of quasiregular mappings

2012

We establish a rescaling theorem for isolated essential singularities of quasiregular mappings. As a consequence we show that the class of closed manifolds receiving a quasiregular mapping from a punctured unit ball with an essential singularity at the origin is exactly the class of closed quasiregularly elliptic manifolds, that is, closed manifolds receiving a non-constant quasiregular mapping from a Euclidean space.

Volatile components from aerial parts of Centaurea gracilenta and C. ovina ssp. besserana growing wild in Bulgaria

2011

The essential oils of Centaurea gracilenta Velen. (CG) and C. ovina Pall. ex Willd. ssp. besserana (DC.) Dostál (COB) growing wild in Bulgaria, were studied by GC and GC-MS. Forty-five compounds for CG, representing the 90.1% of the oil, and 68 compounds for COB, representing the 91.9% of the oil, were identified. The oils were rich in sesquiterpenoids (33.4% for CG and 27.3% for COB), hydrocarbons (28.3% for CG and 10.7% for COB) and carbonylic compounds (12.7% for CG and 13.1% for COB). Fatty acids were abundant only for COB (31.3%). beta-Eudesmol (12.8%), nonacosane (11.8%) and p-vinyl guiacol (7.5%) were recognized as the main constituents for CG, while hexadecanoic acid (21.4%), spathu…

2012

Any study of myeloproliferative neoplasms (MPNs) that lacks adequate clinical input is doomed to cause diagnostic uncertainty and increased controversy. In the paper by Buhr et al. published in Haematologica,[1][1] the authors studied 102 cases of essential thrombocythemia (ET) and early primary

Chemical composition of the essential oil of Phagnalon saxatile (L.) Cass. (Asteraceae) growing wild in Southern Italy

2005

Abstract The essential oil from aerial parts of Phagnalon saxatile (L.) Cass. (Asteraceae) was obtained by hydrodistillation. The oil content was 0.15% (v/w), on a dry weight basis. The oil composition was analyzed by GC and GC/MS. Altogether 66 compounds were identified accounting for 93.2% of the oil. Sesquiterpenes represent the 23.9% of the oil. In the oil were also present fatty acids (21.8%) and waxes (19.3%). The oil shows no antibacterial activity.

A review of Devenir Soi by Jacques Attali: through the lenses of liberalism and Buddhism

2015

Purpose – The purpose of this paper is to reinterpret Attali’s worldview through the lenses of liberalism and Buddhism by mobilizing the relevant literature, beyond the mere book review. This paper is an essay based on the book “Devenir Soi” by Jacques Attali, published in France in 2014. These analytical grids were chosen, because freedom and self-realization are two themes that pervade the book. Design/methodology/approach – After presenting the book structure, the objective and the methodological approach, we uncover Attali’s interrogation, namely how to free oneself from the omnipresence of evil, the withering away of the State and growing xenophobic populist self-entitlement. We make …

Development and characterization of essential oil component-based polymer films: a potential approach to reduce bacterial biofilm

2013

The development of new polymeric materials aimed to control the bacterial biofilm appears to be an important practical approach. The goal of the present study was to prepare and characterize poly(ethylene-co-vinyl acetate) copolymer (EVA) films containing citronellol, eugenol, and linalool and evaluate their efficiency on growth and biofilm formation of Listeria monocytogenes, Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, and Pseudomonas aeruginosa in monospecies and dual species. The results showed that the addition of oil components influenced the elastic modulus (15 % decrease), the tensile stress (30 % decrease), the elongation at break (10 % increase), and the co…

Extraction of essential oil from Aloysia citriodora Palau leaves using continuous and pulsed ultrasound: Kinetics, antioxidant activity and antimicro…

2018

International audience; The impact of continuous and pulsed ultrasound pre-treatments (15, 30 and 45 min) followed by conventional hydrodistillation on the characteristics of extracted essential oils (EOs) from dried leaves of Aloysia citriodora Palau was evaluated for the first time. Chemical composition of EOs, antibacterial and antioxidant activities, as well as the contents in heavy metals (iron, copper, lead, arsenic, and cadmium) were determined. Pretreating the leaves with ultrasound (continuous and pulsed), before hydrodistillation, resulted in shorter extraction time (93.81–121.16 min) and higher extraction yields (2.8 (v/w) %) (p < 0.05), compared to the non-sonicated leaves (extr…
