Small Residues Inhibit Homo-Dimerization of the Human Carbonic Anhydrase XII Transmembrane Domain
2021
Amino acids with small side chains and motifs of small residues in a distance of four are rather abundant in human single-span transmembrane helices. While interaction of such helices appears to be common, the role of the small residues in mediating and/or stabilizing transmembrane helix oligomers remains mostly elusive. Yet, the mere existence of (small)xxx(small) motifs in transmembrane helices is frequently used to model dimeric TM helix structures. The single transmembrane helix of the human carbonic anhydrases XII contains a large number of amino acids with small side chains, and critical involvement of these small amino acids in dimerization of the transmembrane domain has been sugges…
El fundamento liberal del derecho a la intimidad
2021
T: The right to privacy is configured as a ?retaining wall? against State interference into the private sphere of people?s life. Throughout this work we will try to expose the philosophical-liberal foundations that have led us to what is now conceived as the ?right to privacy?.
Tra moderno e contemporaneo: Alessandro Bazan in mostra a Palermo
2012
L'articolo è dedicato alla mostra personale dell'artista siciliano Alessandro Bazan presso la Galleria d'Arte Moderna di Palermo
Arte contemporanea e sistema dell’arte. Una breve ricognizione
2018
Il contributo prende in esame i principali soggetti del sistema dell’arte, come artisti, curatori, critici, collezionisti, gallerie, musei e fiere, analizzando la nascita del fenomeno in riferimento a protagonisti e movimenti di epoca contemporanea e offrendo spunti di riflessione sulle dinamiche che regolano tale network complesso e affascinate. The contribution explores the main players of the art system (artists, curators, critics, collectors, galleries, museums and art fairs) examining this phenomenon in reference to contemporary artists and movements and offering a reflection on the dynamics which regulate this complex and fascinating network.
Optimal Guard Placement Problem Under L-Visibility
2006
Two points a and b in the presence of polygonal obstacles are L-visible if the length of the shortest path avoiding obstacles is no more than L. For a given convex polygon Q, Gewali et al [4]. addressed the guard placement problem on the exterior boundary that will cover the maximum area exterior to the polygon under L-visibility. They proposed a linear time algorithm for some given value of L. When the length L is greater than half of the perimeter, they declared that problem as open. Here we address that open problem and present an algorithm whose time complexity is linear in number of vertices of the polygon.
Microbiome symbionts and diet diversity incur costs on the immune system of insect larvae
2017
Communities of symbiotic microorganisms that colonize the gastrointestinal tract play an important role in food digestion and protection against opportunistic microbes. Diet diversity increases the number of symbionts in the intestines, a benefit that is considered to impose no cost for the host organism. However, less is known about the possible immunological investments that hosts have to make in order to control the infections caused by symbiont populations that increase due to diet diversity. By using taxonomical composition analysis of the 16S rRNA V3 region, we show that Enterococci are the dominating group of bacteria in the midgut of the larvae of the greater wax moth (Galleria mell…
Cylindrical optical microcavities: Basic properties and sensor applications
2011
Abstract A detailed theoretical analysis of the basic properties of whispering-gallery modes (WGM) of thin capillaries is presented. The sensitivity of the resonances, as well as the Q factor is analyzed as a function of the structural parameters of the capillary and the refractive index inside the capillary. A practical application where thin capillaries are used for the measurement of glucose concentration in water is presented as a chemical sensor demonstrator. A best sensitivity of 1.24 nm/% of glucose concentration in water is reported, which corresponds to more than 850 nm/RIU. Additionally, different experimental approaches are discussed to improve the sensitivity and the detection l…
Tunable narrowband fiber laser with feedback based on whispering gallery mode resonances of a cylindrical microresonator.
2013
Narrowband filtering based on whispering gallery modes of a slightly tapered cylindrical optical microresonator was used to implement a tunable narrowband erbium-doped fiber laser. The laser can be set to emit a single longitudinal cavity mode (single frequency), although the laser cavity is a few meters long. In the single-frequency regime the laser can emit a maximum power of 0.380 mW with a linewidth <35 kHz and a signal-to-noise ratio exceeding 50 dB. Tunability is achieved by sliding the excitation point along the microcylinder. A tuning range of 1.16 nm is demonstrated.
EXPA, Galleria di Architettura, Grafica e Design
2006
EXPA é l'acronimo di Exhibition Palermo, un esplicito riferimento alla principale attività che si svolge nella galleria, quella espositiva, e alla sua precisa identità territoriale. La Galleria di architettura, grafica e design, é posta lungo la via Alloro nel quartiere storico della Kalsa. La sua collocazione geografica è uno dei fattori determinanti la scelta del caso, in quanto, insieme al complesso delle attività culturali' che vi si svolgono, costituisce i due aspetti non separabili del processo di valorizzazione e di diffusione della cultura del design, che si sviluppa attraverso una sinergia di collaborazioni tra enti pubblici e privati, dipartimenti e facoltà, studenti, laureati, pr…
Image og the Teacher in Schools Websites – Representative of the School
2015
Article consists of three parts - theoretical, empirical research and recommendations for improvement the school website photo galleries. Publication analyses ideas (Weber&amp;Mitchell, Ķestere, Kaļķe, Fischer&amp;Kiefer, Veide) that reveal importance of the teacher's image in the representation of the school, significance of the picture and selfpromotion in the school context. The empirical study consider teacher’s image in 17 Latvian school website photo galleries and surveys 102 primary school student’s parents to find out their views on the school website photo galleries impact on the selection of the school for their children. Analysis of the theoretical literature and interpre…
