Vegetation, soils, and humus forms of Sardinian holm oak forests and approximated cross-harmonization of vegetation types, WRB Soil Groups and humus …
2018
Five plant communities, related to elevation above sea level and geological substrata, are recognized in the holm oak forests of Sardinia (Italy). These forests show a considerable inhomogeneous structure due to present day and past uses. Coppice management prevails, influencing the quantity and quality of organic horizons. Most frequent mineral soils are Cambisols, Leptosols, and Regosols. Regarding the humus forms, Moder and, with less extent, Amphi, are prevailing. Furthermore, the paper presents a synoptic table giving a rough picture of the relationships between vegetation types, WRB Soil Groups and humus forms in selected Mediterranean ecosystems.
Moderne Therapie bei akutem Koronarsyndrom
2002
Inhibition of platelet aggregation with aspirin and anticoagulation with unfractionated heparin can be considered the gold standard treatment of patients with acute coronary syndromes. Replacement of unfractionated heparins by low-molecular weight heparins seem to further improve the cardiovascular risk. Additional treatment with glycoprotein IIb/IIIa receptor blockers led to a further reduction of the clinical event rate, especially in patients undergoing coronary interventions during an acute coronary syndrome (more than 30% relative risk reduction). However, the latter substances did only lead to marginal improvements in the setting of a conservative stabilization of patients with acute …
Isotopic Niche and Trophic Position of the Invasive Portunid Portunus segnis Forskål, (1775) in Elounda Bay (Crete Island, Eastern Mediterranean)
2022
There is a growing recognition that an advanced understanding of the trophic characteristics of an invasive consumer can provide important information on its ecological impact. In recent years, the blue swimming crab Portunus segnis, one of the earliest Lessepsian invaders, has considerably expanded its distribution range in the Mediterranean Sea, yet, its trophic habits in invaded areas remain scarcely investigated. In this study, we used carbon and nitrogen stable isotopes analysis (SIA) to determine the trophic position and isotopic niche of the crab compared with other representatives of the flora and fauna occurring in Elounda Bay (Crete). P. segnis showed a trophic position of 3.9, hi…
Renormalization-group analysis for the transition to chaos in Hamiltonian systems
2002
Abstract We study the stability of Hamiltonian systems in classical mechanics with two degrees of freedom by renormalization-group methods. One of the key mechanisms of the transition to chaos is the break-up of invariant tori, which plays an essential role in the large scale and long-term behavior. The aim is to determine the threshold of break-up of invariant tori and its mechanism. The idea is to construct a renormalization transformation as a canonical change of coordinates, which deals with the dominant resonances leading to qualitative changes in the dynamics. Numerical results show that this transformation is an efficient tool for the determination of the threshold of the break-up of…
Surgical management of acute angle-closure glaucoma after toric implantable contact lens implantation
2006
A case of pupillary block after implantation of an implantable contact lens (ICL) is reported, and surgical management and prevention are discussed. In a myopic patient, the best corrected visual acuity in the right eye was 20/50 with -15.50 -3.00 x 175. After uneventful implantation of an ICL, painful acute glaucoma developed with an intraocular pressure beyond measurable values. Apparent anterior vaulting of the ICL suggested a sizing problem. In a situation of a mid-wide dilated pupil, immediate explantation of the ICL was performed. Then, using a preoperative iris photography as guidance, an anterior chamber iris-claw toric phakic intraocular lens was implanted. On postoperative examina…
Ensenyant Horta, aprenent paisatge. Anàlisi dels discursos educatius sobre el paisatge de l'Horta i propostes de millora
2017
Al País Valencià existeixen espais agraris periurbans que conformen paisatges d'especial singularitat com ara l'Horta de València, que malgrat la seua importància està travessada per múltiples problemàtiques. Als centres d'educació secundària la majoria dels discursos sobre espai agrari que es transmeten des dels manuals escolars i el professorat s'hi apropen de manera taxonòmica, pobre i simplificadora, així com des d'un punt de vista únicament productivista, obviant tota la resta de dimensions des de les quals es pot analitzar un paisatge. Un ensenyament més convenient sobre els espais agraris a la comarca de l'Horta hauria d'estar íntimament lligat al medi local, així com contemplar tote…
NEONAX trial: Neoadjuvant plus adjuvant or only adjuvant nab-paclitaxel plus gemcitabine for resectable pancreatic cancer, a phase II study of the AI…
2019
4128 Background: Survival in pancreatic cancer (PDAC) is still poor even after curatively intended resection. Perioperative treatment approaches improve outcome in various tumor entities. Data on perioperative treatment in resectable PDAC are limited and there is a debate whether neoadjuvant treatment might impair subsequent surgery by adding perioperative morbidity or mortality. Methods: NEONAX is a randomized phase II study (planned 166 patients) of perioperative gemcitabine/nab-paclitaxel (Arm A: 2 pre- and 4 post-operative cycles, Arm B: 6 cycles adjuvant) for patients with primarily resectable PDAC. Primary objective is DFS at 18 months after randomization. Secondary objectives are 3-…
Use of triacylglycerol profiles established by high performance liquid chromatography with ultraviolet–visible detection to predict the botanical ori…
2011
A method for the determination of triacylglycerols (TAGs) in vegetable oils from different botanical origins by HPLC with UV–vis detection has been developed. Using a core-shell particle packed column (C18, 2.6 micron), TAG separation was optimized in terms of mobile phase composition and column temperature. Using isocratic elution with acetonitrile/n-pentanol at 10 °C, excellent efficiency with good resolution between most of the TAG peak pairs, within a total analysis time of 15 min, was achieved. Using mass spectrometry detection, a total of 15 peaks, which were common to oils of six different botanical origins (corn, extra virgin olive, grapeseed, hazelnut, peanut and soybean) were iden…
The Dark Side of Value Co-Creation: The Example of French Commercial Architecture
2018
Innovation is a network activity where different actors collaborate. An ethnographic survey of the French commercial architecture industry highlights the ambivalence of this co-production process. The results identify the sources of co-creation and co-destruction related both to the motivations of the actors and their interactions and examines their consequences. Retailers are encouraged to reposition themselves as project leaders, responsible for both assigning roles and mediating between the creative and technical functions. The development of new communication platforms to overcome interpretive biases between the diverse set of actors is also recommended.
Reflexiones sobre el pintor Lluís Dalmau a propósito de un retablo para Molins de Rei (1451)
2018
El presente texto plantea una serie de reflexiones sobre la figura del pintor Lluís Dalmau, uno de los introductores de la pintura gótica flamenca en la Corona de Aragón. El análisis surge a partir de la presentación de un nuevo documento inédito sobre un retablo contratado en 1451 por Isabel de Requesens, esposa del gobernador de Cataluña, Galceran de Requesens, para la baronía de Molins de Rei (Barcelona). El documento sitúa al pintor realizando este encargo en Valencia, lo que supone un regreso hasta ahora desconocido a su ciudad natal tras haber realizado la tabla de la Mare de Déu dels Consellers, de Barcelona (1443-1445), y el retablo de san Baudilio, de Sant Boi de Llobregat (1448). …
