Aminoacid zwitterions in solution : Geometric, energetic, and vibrational analysis using density functional theory-continuum model calculations

1998

Glycine and alanine aminoacids chemistry in solution is explored using a hybrid three parameters density functional (B3PW91) together with a continuum model. Geometries, energies, and vibrational spectra of glycine and alanine zwitterions are studied at the B3PW91/6-31+G∗∗ level and the results compared with those obtained at the HF and MP2/6-31+G∗∗ levels. Solvents effects are incorporated by means of an ellipsoidal cavity model with a multipolar expansion (up to sixth order) of the solute’s electrostatic potential. Our results confirm the validity of the B3PW91 functional for studying aminoacid chemistry in solution. Taking into account the more favorable scaling behavior of density funct…

Alchimia e Memphis. I colori progettati del design

2012

Il design italiano, tra anni Settanta e Ottanta, viene marchiato a fuoco dalla definizione “Made in Italy” che ne riporta provenienza geografica, qualità progettuale e innovativa ed eccellenza assoluta. In tale scenario, all’interno di tante realtà legate al design e diffuse capillarmente sul territorio, si continua a sperimentare in modo ininterrotto, e in ogni settore legato alla progettazione, alla produzione, alla ricerca tecnologica e dei nuovi materiali. Scenario nel quale si muovono anche le realtà di Alchimia e Memphis che ripensano il progetto, attribuiscono nuovo valore a elementi come il colore e la decorazione, costruiscono nuovi lessici. In the 1970s and 1980s, the identity of …

Alessandro Costariol. 永远的视觉设计师 / Alessandro Costariol. Remote future visual designer

2010

永远的视觉设计师 如果用一个词来简洁鲜明的概括一个人的话,我认 为永恒一词是最佳选择。这个词是个近代词汇, 始创于20世纪,表达出一种时代特性。在逻辑学 和语言学领域重复出现。它标志着客体和时间连 续性的中断。并赋予客体以特权, 跨越时间的限 制,忽略时间发展的顺序和速度,使客体处于一种 独立的暂停状态。永恒所表达的含义如同一个现代 人穿了一件古时的衣服,这种古时和现代的不同风 格常常冲突不断,就像一道糖醋口味的菜肴中,一 个口味偏咸的人却意外的品尝到了甜味。 If you could define a person with only one term, to have a concise, sharp and lapidary picture of him, then I think the word I'd choose to refer to Alessandro Costariol, is timeless. This is a rather recent term, coined in the twentieth century, expression of contemporaneity, recurrent in the philosophical and linguistic fields, which marks a break in continuity between object and time, giving the first a privileged status that allows it to cross the second, ign…

Una pedagogia della vita emotiva

2014

Il contributo presenta le linee di una fenomenologa delle emozioni, il cui assunto principale è renderne evidente la portata referenziale. Vengono così giustificate come vie specifiche che consentono la comprensione degli aspetti singolari delle persone che hanno parte ai mondi della nostra vita. È una prospettiva critica rispetto alla cultura che sembra oggi prevalente e che vede invece nelle emozioni quasi esclusivamente il loro aspetto espressivo. Le emozioni come vie di conoscenza hanno poi una loro evoluzione caratteristica, crescendo in consapevolezza e acquistando la dimensione della durata. Viste nelle forme di reazione «favorevole» alla presenza dell’altro sono forme di amore e por…

Additivity of affine designs

2020

We show that any affine block design $$\mathcal{D}=(\mathcal{P},\mathcal{B})$$ is a subset of a suitable commutative group $${\mathfrak {G}}_\mathcal{D},$$ with the property that a k-subset of $$\mathcal{P}$$ is a block of $$\mathcal{D}$$ if and only if its k elements sum up to zero. As a consequence, the group of automorphisms of any affine design $$\mathcal{D}$$ is the group of automorphisms of $${\mathfrak {G}}_\mathcal{D}$$ that leave $$\mathcal P$$ invariant. Whenever k is a prime p,  $${\mathfrak {G}}_\mathcal{D}$$ is an elementary abelian p-group.

Relative principal congruences in congruence-modular quasivarieties

1998

The problem of definability of relative principal congruences in relatively congruence modular (RCM) quasivarieties is investigated. The RCM quasivarieties are characterized in terms of parameterized families of finite sets of pairs of terms which define relative principal congruences.

Representations of Certain Banach C*-modules

2004

The possibility of extending the well known Gelfand–Naimark– Segal representation of *-algebras to certain Banach C*-modules is studied. For this aim the notion of modular biweight on a Banach C*-module is introduced. For the particular class of strict pre CQ*-algebras, two different types of representations are investigated.
