Sobre la prosa d'art en Isabel de Villena

2011

Aproximació a l"ús que fa Isabel de Villena a la seua Vita Christi de la denominada prosa d"art, estil que té el seu origen en les artes dictaminis medievals. S"hi mostra que Villena sovint coincideix amb les eleccions retòriques de Joan Roís de Corella; almenys amb les de la fase de les proses mitològiques, que es prenen com a referència per existir-ne ja una caracterització retòrica. A first approach to Isabel de Villena¿s use of the so-called 'prosa d¿art' in her Vita Christi, a style originated in the medieval artes dictaminis. It is shown that usually Villena¿s rhetoric preferences are similar to Joan Roís de Corella¿s; at least to those in his proses mitològiques period, which are sta…

Entre Trapani et Tunis. De la période du Risorgimento à la fin du Protectorat français: parcours de travailleurs et d’entrepreneurs au-delà du Canal …

2019

Sin dai tempi più antichi, il Canale di Sicilia e la città di Trapani hanno costituito un ponte naturale fra il Maghreb e la Sicilia. Il saggio mette a sistema alcuni studi sugli architetti ed imprenditori di origine trapanese che emigrarono in Tunisia fra il XVIII e XIX secolo e ne propone una lettura inedita. Il fil rouge che lega Giuseppe Abita, la famiglia di imprenditori Canino e Domenico Basciano riguarda sia la loro provenienza dalla città siciliana, ma soprattutto l'importante contributo che essi hanno trasferito nell'architettura del periodo coloniale e post-coloniale francese nel Maghreb.

Hybrid layers of etch-and-rinse versus self-etching adhesive systems.

2010

Objective: To evaluate the effectiveness in the formation of resin tags, adhesive lateral branches and hybrid layers of five adhesive systems, when bonding to dentine. Material and Methods: Flat dentin surfaces from 25 molars were bonded with several adhesive systems according to the manufacturers? instructions. Composite build-ups were constructed incrementally with Tetric Ceram. The Specimens were sectioned parallel to the long axis. One section was treated with phosphoric acid and sodium hypochlorite in order to reveal the hybrid layer formation. The other section was stored in 30% hydrochloric acid to detect resin tags and adhesive lateral branch formation. Results: The two etch-and-rin…

Specific muscle-tendon architecture in elite Kenyan distance runners

2013

The Achilles tendon moment arm (MA_AT) and foot lever ratio (FLR) can play important roles for force production and movement economy during locomotion. This notion has become more relevant, and suggestion has been given that the Kenyan runners belonging to the world elite would have specific anatomical, mechanical, and functional properties in their lower limbs and that this feature could be responsible for their high running economy. The present study aimed to characterize the AT of elite Kenyan distance runners as compared with Japanese ones, and to examine the potential relationship with their running performance. Ultrasonography was used to measure AT cross-sectional area and AT soleus …

Significance of passively induced stretch reflexes on achilles tendon force enhancement

1998

An in vivo buckle transducer technique was applied to study the reflex contribution to ATF enhancement during passive dorsiflexion stretches. Single stretches led to a linear ATF increase in the absence of an EMG reflex response, whereas clear ATF enhancement over the passive component occurred 13-15 ms after the onset of EMG responses. To quantify the reflexly induced increase in ATF, the stretched position was maintained. The mean reflex effect was two to four times greater than the passive stretch effect.

Osseotite caricati a due mesi nei settori posteriori del mascellare superiore: controllo a 2 anni di due casi clinici

2003

Aim Acid etched surface implants determine high clinical success rates, but little information is available about early loading in the posterior region of the maxilla, area at risk of failure. The aim of this work is to present two case reports of oral rehabilitation through acid etched surface implants (Osseotite, Implant Innovations - 3i, West Palm Beach, FL) loaded two months after insertion in the posterior maxilla. Materials and methods The success of Osseotite implants was assessed 12 and 24 months after prosthetic loading according to Albrektsson et al. criteria (1986). Results No clinical or radiographic signs of implant failure were observed during the two years follow-up. Conclusi…

Acute effects of short-duration isolated static stretching or combined with dynamic exercises on strength, jump and sprint performance

2013

Summary Objective This study aimed to investigate the acute effects of a short-duration isolated static stretching or combined with dynamic plyometric exercises on the performance of some anaerobic parameters (strength, jumping and sprinting). Methods During three distinct sessions and after a standardized warm-up, 15 participants randomly performed static stretching exercises alone, static stretching combined with plyometric exercises and no stretch. Total stretch duration was 20 seconds long per muscle group (quadriceps, hamstrings and calf muscles). Tests included maximal quadriceps muscle strength, countermovement jumps and 15 m sprints. Results Whatever the condition, maximal strength …

Current dental adhesives systems. A narrative review.

2012

Adhesive dentistry is based on the development of materials which establish an effective bond with the tooth tissues. In this context, adhesive systems have attracted considerable research interest in recent years. Successful adhesive bonding depends on the chemistry of the adhesive, on appropriate clinical handling of the material as well as on the knowledge of the morphological changes caused on dental tissue by different bonding procedures. This paper outlines the status of contemporary adhesive systems, with particular emphasis on chemical characteristics and mode of interaction of the adhesives with enamel and dentinal tissues. Dental adhesives are used for several clinical application…

Neuromuscular function and mechanical efficiency of human leg extensor muscles during jumping exercises

1982

The influence of prestretch amplitude on the mechanical efficiency was examined with 5 subjects, who performed 5 different series of vertical jumps, each of which differed with respect to the mechanics of the knee joint action during the prestretch (eccentric) phase of the contact on the floor. Electromyographic activity was recorded from the major extensor muscles during the entire work period of 1 min per series. In addition, expired air was collected during the test and recovery for determination of energy expenditure. Mechanical work was calculated from the vertical displacement of the body during the jumps. The results indicated that high net efficiency of 38.7% was observed in conditi…
