Análisis de dos clavos y un rodamiento del pecio Bou Ferrer (La Vila-Joiosa, Alicante)

2020

El pecio Bou Ferrer contiene los restos sumergidos de una nave de comercio romana altoimperial que conserva una parte importante de su arquitectura naval. Analizamos tres objetos de metal procedentes del yacimiento, dos clavos y un hipotético rodamiento de la bomba de achique, para conocer la composición elemental. El resultado ha revelado que los clavos son de cobre y el cojinete de una aleación ternaria de bronce que contiene cobre, estaño y plomo. Este hallazgo abre la posibilidad de investigar el uso especializado del bronce plomado para mejorar el rendimiento mecánico de las bombas de achique en los barcos romanos. The Bou Ferrer wreck contains the underwater remains of a high-empire R…

Understorey plant and soil responses to disturbance and increased nitrogen in boreal forests

2009

Question: How do N fertilization and disturbance affect the understorey vegetation, microbial properties and soil nutrient concentration in boreal forests? Location: Kuusamo (66°22′N; 29°18′E) and Oulu (65°02′N; 25°47′E) in northern Finland. Methods: We conducted a fully factorial experiment with three factors: site (two levels), N fertilization (four levels) and disturbance (two levels). We measured treatment effects on understorey biomass, vegetation structure, and plant, soil and microbial N and C concentrations. Results: The understorey biomass was not affected by fertilization either in the control or in the disturbance treatment. Fertilization reduced the biomass of deciduous Vacciniu…

Effects of artificial plant cover on plant colonization of a bare peat surface

1992

. This paper describes the effect of artificial plant cover on plant colonization of a bare peat surface, resulting from peat harvesting. Plant species colonization was compared on plots supplied with plastic models simulating Vaccinium vitis-idaea plants and plots without this artificial cover. After two growing seasons, species composition and total biomass of the established plant cover were similar in the two plot types. However, the number of established seedlings in the plots with artificial cover was significantly higher than that in the plots without cover. Out of 13 species observed four differed significantly in their performance on the two plot types. Betula spec. had both higher…

A Retrospective Analysis about Frequency of Monitoring in Italian Chronic Myeloid Leukemia Patients after Discontinuation

2019

Background: Successful tyrosine-kinase inhibitors (TKIs) discontinuation has been obtained in some patients (pts) with chronic-phase chronic myeloid leukemia (CP-CML). Careful molecular monitoring after discontinuation is the key to guarantee the safety, in terms of prompt resumption of therapy according to retreatment threshold criteria. It was observed that the majority of relapses usually occur during the first 6 months after TKI discontinuation [Saussele S, Lancet Oncol 2018; Etienne G, JCO 2017], accounting for the monthly quantitative PCR (qPCR) that all prospective protocols included in the trial design at least during the first half-year. Two studies [Kong HJ, Cancer 2017; Shanmugan…

Campsite choice and the camping tourism experience: Investigating decisive campsite attributes using relevance-determinance analysis

2017

Abstract Camping tourism represents a growing part of the overall tourism industry. Despite this fact, this form of tourism has so far been rather neglected by tourism and hospitality research. Using a case study of a major campsite operator in the coastal part of Croatia, this study thus aims to contribute to the understanding of this specific tourist segment. In particular, a relevance-determinance analysis is conducted to reveal most decisive attributes for campsite choice, on the one hand, and for the actual campsite experience, on the other hand. Overall, the results provide valuable insight to practitioners, especially for the purposes of campsite marketing and experience management.

High-Frequency Polarization Variability from Active Galactic Nuclei

2021

The linear polarization of non-thermal emission encodes information about the structure of the magnetic fields, either from the region where the emission is produced (i.e., the intrinsic polarization angle) and/or from the screens of magnetized plasma that may be located on its way towards Earth (i.e., the effect of Faraday rotation). In addition, the variability timescale of the polarized emission, or its Faraday rotation, can be used to estimate the size of the region where the emission (or the Faraday rotation) originates. The observation of polarized emission from active galactic nuclei (AGN) and, in particular, its time evolution, also provides information about the critical role that …
