Percepción, escritura y funciones de la otredad oriental y la maravilla en los libros de viajes de la España medieval (ss. XIV-XV)

2023

El estudio se centra en un análisis histórico y cultural sobre la otredad y la maravilla en los libros de viajes de la España medieval durante los siglos XIV y XV. En primer lugar, se examina el concepto de otredad oriental como parte de la relación de alteridad y etnicidad entre los viajeros europeos y el contacto con los pueblos de Asia. En segundo lugar, se estudia la presencia de lo maravilloso en los libros de viajes medievales hispánicos, analizando sus categorías conceptuales, sus usos en la escritura de viajes y sus funciones discursivas y narrativas. A partir de ahí, se revisan los casos de los viajeros y sus percepciones de la otredad, remarcando los aspectos exóticos, salvajes y …

ON SYLOW NORMALIZERS OF FINITE GROUPS

2013

[EN] The paper considers the influence of Sylow normalizers, i.e. normalizers of Sylow subgroups, on the structure of finite groups. In the universe of finite soluble groups it is known that classes of groups with nilpotent Hall subgroups for given sets of primes are exactly the subgroup- closed saturated formations satisfying the following property: a group belongs to the class if and only if its Sylow normalizers do so. The paper analyzes the extension of this research to the universe of all finite groups.

On second minimal subgroups of Sylow subgroups of finite groups

2011

A subgroup H of a finite group G is a partial CAP-subgroup of G if there is a chief series of G such that H either covers or avoids its chief factors. Partial cover and avoidance property has turned out to be very useful to clear up the group structure. In this paper, finite groups in which the second minimal subgroups of their Sylow p-subgroups, p a fixed prime, are partial CAP-subgroups are completely classified.

On some classes of supersoluble groups

2007

[EN] Finite groups G for which for every subgroup H and for all primes q dividing the index |G:H| there exists a subgroup K of G such that H is contained in K and |K:H|=q are called Y-groups. Groups in which subnormal subgroups permute with all Sylow subgroups are called PST-groups. In this paper a local version of the Y-property leading to a local characterisation of Y-groups, from which the classical characterisation emerges, is introduced. The relationship between PST-groups and Y-groups is also analysed.

Finite groups with all minimal subgroups solitary

2016

We give a complete classification of the finite groups with a unique subgroup of order p for each prime p dividing its order. All the groups considered in this paper will be finite. One of the most fruitful lines in the research in abstract group theory during the last years has been the study of groups in which the members of a certain family of subgroups satisfy a certain subgroup embedding property. The family of the subgroups of prime order (also called minimal subgroups) has attracted the interest of many mathematicians. For example, a well-known result of Itˆo (see [8, Kapitel III, Satz 5.3; 9]) states that a group of odd order with all minimal subgroups in the center is nilpotent. Th…

p38 MAPK in cadmium-treated MDA-MB231 breast cancer cells

2008

Activation of the p38MAPK cascade is associated with upregulation of TNF alpha receptors in the spinal motor neurons of mouse models of familial ALS.

2005

Phosphorylated p38 mitogen-activated protein kinase (p38MAPK), but not activated c-jun-N-terminal kinase (JNK), increases in the motor neurons of transgenic mice overexpressing ALS-linked SOD1 mutants at different stages of the disease. This effect is associated with a selective increase of phosphorylated MKK3-6, MKK4 and ASK1 and a concomitant upregulation of the TNFalpha receptors (TNFR1 and TNFR2), but not IL1beta and Fas receptors. Activation of both p38 MAPK and JNK occurs in the activated microglial cells of SOD1 mutant mice at the advanced stage of the disease; however, this effect is not accompanied by the concomitant activation of the upstream kinases ASK1 and MKK3,4,6, while both …

Net currents obtained from zero-average potentials in single amphoteric nanopores

2013

We have studied experimentally and theoretically the rectifying properties of a single asymmetric nanopore functionalized with amphoteric lysine groups and characterized the net current obtained with zero-average time dependent potentials. The pH-controlled rectification phenomena may be relevant to bio-electrochemistry, pH sensing and regulation, and energy conversion. (C) 2013 Elsevier B.V. All rights reserved.

Un parco possibile: luoghi e società tra urbanistica e paesaggio

2008

Le trasformazioni possibili del ponente palermitano tra paesaggio, urbanistica e progetto del territorio. In particolare il territorio di Boccadifalco porta con sé numerose istanze da recuperare e valorizzare, sul piano vegetale e naturalistico, sul piano architettonico e monumentale. Nell'articolo e nel volume sono tratteggiati alcuni modelli possibili ed alcune esperienze condotte nella direzione del recupero e della tutela di aree urbane non edificate, anche con vocazioni e caratteri differenti, che hanno costituito ed incrementato la dotazione di verde di alcune città italiane ed europee. Per volere citare qualche esempio di città che possano somigliare al caso di Palermo per dimensione…
