A new population of terrestrial gamma‐ray flashes in the RHESSI data

2015

Terrestrial gamma-ray flashes (TGFs) are the most energetic photon phenomenon occurring naturally on Earth. An outstanding question is as follows: Are these flashes just a rare exotic phenomenon or are they an intrinsic part of lightning discharges and therefore occurring more frequently than previously thought? All measurements of TGFs so far have been limited by the dynamic range and sensitivity of spaceborne instruments. In this paper we show that there is a new population of weak TGFs that has not been identified by search algorithms. We use the World Wide Lightning Location Network (WWLLN) to identify lightning that occurred in 2006 and 2012 within the 800 km field of view of Reuven Ra…

The holonic approach for flexible production: a theoretical framework

2011

This paper discusses the body of knowledge about Holonic Approach to theoretically demonstrate how Holonic Production System (HPS) can be a convincing choice to overcome the problems of traditional production systems? architectures. Today, enterprises are trying to find ways to manage the growing environmental complexity that is well described by Complex Systems Theory (CST). After the focus on the main problem regarding environmental complexity, the Holonic system and the Holonic Production System will be analyzed. The paper will focus the potential of HPS to adapt and react to changes in the business environment whilst being able to maintain systemic synergies and coordination through the…

Efficiency 4.0 for Industry 4.0

2019

Operators of cyber-physical production system (CPPS) will use handheld interactive control panels for supervising production processes. These interactive and handheld control panels will present numerous sensors data. Processing of such complex data for task fulfilment in critical scenario will cause cognitive workload on operators. The prevalent industry efficiency measures so far have focused on human physical workload measures; the human cognitive load has not been considered in industrial practices. Smart factories in the near future will begin to integrate intelligent machines with complex communication network systems between human and machines. In this paper, we argue that the changi…

Le anfore fenicio-puniche prodotte nel Mediterraneo occidentale: caratteristiche petrografiche degli impasti siciliani e spagnoli.

2009

The aim of this paper is to provide well-stated petrographic reference groups for the recognition of several Sicilian and Spanish Phoenician-Punic production centres in order to facilitate an instrument of further objective support for amphorae provenance. This instrument is based on the crosschecking between data provided by typological studies and the thinsection analysis of amphorae fabrics. It is worth noting that this is only a first step within the framework of a larger research project focused in the creation of an Atlas of Phoenician and Punic Amphorae in the Western Mediterranean including both archaeological and petrographic data. In this context a systematical work on the known p…

Volatiles in pantellerite magmas: A case study of the Green Tuff Plinian eruption (Island of Pantelleria, Italy)

2013

Abstract The Green Tuff (GT) Plinian eruption, the largest in magnitude at Pantelleria, erupted 3 to 7 km3 DRE of pantellerite magma and a small volume of trachyte. Fifty-nine anorthoclase-hosted melt inclusions from the two basal pumice members were analyzed by FT-IR spectroscopy in order to assess the pre-eruptive H2O content in the pantellerite melt. Microanalytical methods were used to determine major element, Cl, F and S contents. Melt inclusions and glassy groundmasses have a nearly homogeneous pantelleritic composition (peralkaline index = 1.9-2.2) and variable water contents ranging from 1.4 to as high as 4.2 wt %, i.e. much higher than the 1.4 wt % of earlier published studies. The…

The chlorine content is constant at about 1 wt %. Combined Cl and H2O data were used to estimate a confining pressure of about 50 MPa (depth around 2-3 km) for the GT magma chamber. The chamber was characterized by a compositional zoning with a dominant pantellerite overlying a trachyte magma. Soon after the GT eruption intra-caldera volcanism was dominated by the eruption of voluminous trachyte lavaflows while pantellerite melt production resumed after about 20 ka with numerous low-volume mildly explosive (Strombolian) to effusive eruptions. Comparison with data from the literature reveals that despite the differentexplosivity the post-caldera Strombolian eruptions and the GT Plinian eruption were fed by pantelleritic magmas with similar water contents. Chlorine and CO2contents suggest that the young magma reservoirs feeding the Strombolian to effusive activity were deeper (h≥4.5 km) than the much larger (based on erupted volumes) magma chamber which fed the GT eruptionGeologyMelt inclusionsJournal of Volcanology and Geothermal Research

Análisis de la producción y el consumo de información en los artículos españoles sobre bibliometría

1996

We analyze Spanish production of papers on bibliometrics published in Spanish scientific journals and the use of information through the method of bibliographic reference analysis. Publications have been obtained from IME, ICYT and ISOC databases. The number of papers was 101 , with 1848 citations. The most important citations are to journal articles and Spanish publications, but <i>Scientometrics</i> is the most cited journal. Results seem to show that bibliometrics is a young discipline in our country, with an important role of classic authors. Difficulties of access to foreign bibliography produce a high use of Spanish publications. Medicine and Psychology are the most influe…

Speech treatment in nemaline myopathy: A single-subject experimental study

2020

Abstract Purpose The objective of this work was to verify the efficacy of a treatment based on myofunctional therapy techniques which aimed to improve the tongue strength, precision, and speed of a ten-year-old girl with nemaline myopathy (NM) and the repercussions of this therapy on her speech intelligibility. NM is a rare congenital muscle disorder that causes extreme muscle weakness, especially in the face and neck, as well as severe dysarthria and dysphagia, although this does not affect the nervous system or cognitive development. Method This was a single-subject experimental study which used an interrupted pre- and post-treatment time-series design, and which applied autoregressive in…

Detection of genomic regions underlying milk production traits in Valle del Belice dairy sheep using regional heritability mapping

2021

The aim of this study was to identify genomic regions underlying milk production traits in the Valle del Belice dairy sheep using regional heritability mapping (RHM). Repeated measurements for milk yield (MY), fat percentage and yield (F% and FY) and protein percentage and yield (P% and PY), collected over a period of six years (2006-2012) on 481 Valle del Belice ewes, were used for the analysis. Animals were genotyped with the Illumina 50k SNP chip. Variance components, heritabilities, and repeatability within and across lactations were estimated, fitting parity, litter size, season of lambing, and fortnights in milk, as fixed; and additive genetic, permanent environment within and across …
