Conditioned orienting (alpha) and delayed behavioral and evoked neural responses during classical conditioning

1989

A differentiation of short-latency (alpha) and long-latency (delayed) classically conditioned behavioral and evoked neural (hippocampal) responses was attempted. Further, facilitation and retardation of these responses were studied in an experimental design in which 10 paired conditioning sessions either preceded (CC-CO group) or followed (CO-CC group) 10 randomly unpaired presentations of conditioned stimuli (CS) and unconditioned stimuli (UCS). A 2024-ms tone (1000 Hz) was delivered directly through a miniature earphone to the left ear, eliciting an orienting head movement ('alpha' response) to the left. The unconditioned stimulus (UCS) was a direct 1024-ms stimulation of the lateral hypo…

Constituents of regenerated plants of Ophiorrhiza pumila; formation of a new glycocamptothecin and predominant formation of (3R)-deoxypumiloside over…

1997

Abstract The regeneration of plantlets was successful from Ophiorrhiza pumila callus cultures, from which a new glucosyloxy camptothecin, 9-β-glucosyloxycamptothecin, together with 15 metabolites including six camptothecin-related alkaloids was isolated. (3S)-Deoxypumiloside, one of the plausible biogenetic precursors of camptothecin, could not be found, whereas the (3R) epimer was isolated from the regenerated plants.

A remark on weakly convex continuous mappings in topological linear spaces

2009

Abstract Let C be a compact convex subset of a Hausdorff topological linear space and T : C → C a continuous mapping. We characterize those mappings T for which T ( C ) is convexly totally bounded.

TOPOLOGICAL PARTIAL *-ALGEBRAS: BASIC PROPERTIES AND EXAMPLES

1999

Let [Formula: see text] be a partial *-algebra endowed with a topology τ that makes it into a locally convex topological vector space [Formula: see text]. Then [Formula: see text] is called a topological partial *-algebra if it satisfies a number of conditions, which all amount to require that the topology τ fits with the multiplier structure of [Formula: see text]. Besides the obvious cases of topological quasi *-algebras and CQ*-algebras, we examine several classes of potential topological partial *-algebras, either function spaces (lattices of Lp spaces on [0, 1] or on ℝ, amalgam spaces), or partial *-algebras of operators (operators on a partial inner product space, O*-algebras).

Masked form priming in writing words from pictures: evidence for direct retrieval of orthographic codes.

1998

Three experiments used the masked priming paradigm to investigate the role of orthographic and phonological information in written picture naming. In all the experiments, participants had to write the names of pictures as quickly as possible under three different priming conditions. Nonword primes could be: (1) phonologically and orthographically related to the picture name; (2) orthographically related as in (1) but phonologically related to a lesser degree than in (1); (3) orthographically and phonologically unrelated except for the first consonant (or consonant cluster). Orthographic priming effects were observed with a prime exposure duration of 34 ms (Experiments 1 and 2) and of 51 ms …

La genitorialita` procreativa nella coppia omoaffettiva (femminile). Riflessioni a margine di Corte cost. n. 221/2019

2020

Il contributo esamina criticamente la sentenza della Corte costituzionale n. 221 del 2019, che ha affermato la legittimità costituzionale delle previsioni della legge 19 febbraio 2004, n. n. 40, che vietano l’accesso alle tecniche di procreazione medicalmente assistita alle coppie dello stesso sesso. Sulla base di una lettura evolutiva delle regole e dei principî costituzionali e convenzionali implicati, il saggio giunge a una diversa soluzione interpretativa, sostenendo la riconoscibilità del diritto alla genitorialità procreativa degli individui ad orientamento omoaffettivo e la sua compatibilità con l’interesse della prole a nascere e a crescere in un nucleo familiare idoneo ad assicurar…

Determination of disproportionate tenders in public procurement

2013

[EN] Public procurement is one of the fundamental pillars of the construction sector and the understanding of its statutory regulation is one of the keys to success. The government regulates the concept of disproportionate tenders to avoid deals that are too low, something which could jeopardise the execution of the work or cause problems during implementation such as conflicting prices, project modifications and delays. The criteria for determining the disproportionality of the offers are numerous and each contracting authority determines which to use in each process by carrying out a comparative analysis. The results show that the formulas of disproportionality based on a percentage of th…

EU Experts’ Attitude Towards Use of GMO in Food and Feed and Other Industries

2014

Abstract This article examines European Union (EU) experts’ attitude towards use of genetically modified organisms (GMO) in food, feed and other industries with an eye to developing a general model of EU experts’ opinion formation in this area. The gene engineering has seen rapid advances in recent years with a host of new applications in medicine, agriculture, and related fields. Taking into account the history of consumption, social, economic, cultural and other aspects and the risk perception in general regarding these products the consumers’ willingness to buy genetically modified (GM) products varies from country to country as well as attitude of the experts involved in the decision ma…

Probiotics in transition: novel strategies

2015

Regulations regarding health claims made for probiotics demand their proven effectiveness and limit the array of microbial species regarded as safe for live consumption. Novel strategies such as moving to postbiotics and genetically modified probiotics may be necessary to increase the effectiveness of microbial products.
