Medical Student Ultrasound Education, a WFUMB Position Paper, Part II. A consensus statement of ultrasound societies.
2020
Ultrasound is becoming a fundamental first-line diagnostic tool for most medical specialties and an innovative tool to teach anatomy, physiology and pathophysiology to undergraduate and graduate students. However, availability of structured training programs during medical school is lagging behind and many physicians still acquire all their ultrasound skills during postgraduate training.There is wide variation in medical student ultrasound education worldwide. Sharing successful educational strategies from early adopter medical schools and learning from leading education programs should advance the integration of ultrasound into the university medical school curricula. In this overview, we …
La diagnostica chimico-fisica a supporto della conservazione e del restauro delle opere cartacee
2017
Questo contributo è stato prodotto a seguito dell’intervento del Prof. Caponetti e della sessione laboratoriale guidata dalla Dott.ssa Saladino in collaborazione con il Dott. Renda e la Dott.ssa Chirco in cui è stata realizzata una dimostrazione pratica di come si possano eseguire le indagini di materiale cartaceo con strumentazione portatile. Nel presente contributo sono presentate e illustrate alcune delle tecniche di indagine idonee per l’analisi di opere cartacee, ed in particolare alcune di quelle che possono essere applicate mediante strumentazione portatile. Queste tecniche forniscono informazioni complementari e consentono la conoscenza dell’opera stessa (tipologia di carta, tecnica…
Lazos entre lingüística e ideología desde un enfoque historiográfico (ss. XVI-XX)
2020
Los 17 trabajos reunidos en este volumen estudian, desde una óptica historiográfica, la manifestación explícita y/o implícita de ideologías en textos de carácter metalingüístico. Tomando como eje las relaciones entre lingüística e ideología y su proyección en el ámbito social, político o didáctico, se analiza aquí el contenido de obras gramaticales, lexicográficas y ortográficas, historias de lenguas, artículos periodísticos, discursos, manifiestos y otros escritos publicados en la horquilla comprendida entre los siglos XVI y XX. Aunque el grueso de los trabajos se articula en torno a textos sobre el español tanto en su variedad europea como americana, también se da aquí cabida a contribuci…
Alkali-activated mortars for sustainable construction material: effects of binder-to-aggregate ratio and curing conditions
2019
Valorisation and reuse of industrial wastes has become a worldwide compelling topic to improve the sustainability of processes and materials. This paper discusses an alternative way to recycle the biomass fly ash, generated by the kraft pulp industry, to manufacture novel geopolymeric mortars intended for applications in construction. Biomass fly ash was used as a raw material, in partial substitution of the commonly used metakaolin, natural siliceous sand as aggregate. The followed manufacture process is highly simple and reproducible. Various proportions binder to aggregate were tested to study the effect on the final mortars properties. The mortars mechanical resistance was also studied …

Completing the industrial ecology cascade chain in the case of a paper industry - SME potential in industrial ecology
2000
The concept of industrial ecology (IE) adopts the ecosystem principle of roundput in human industrial systems as the emphasis is on the utilization of wastes between different industrial actors. IE faces new challenges, as the emission and waste structures of the industrial world are continuously changing and the importance of the latter steps of the industrial material flows, i.e. the ‘consumption emissions’, is increasing. There is also a lack of waste processors and handlers in these latter steps. This paper considers the IE thesis by focusing on the cascade chain of the paper industry. It is suggested here that SMEs can serve as potential participants in industrial ecosystems, for examp…
Alkali consumption of aliphatic carboxylic acids during alkaline pulping of wood and nonwood feedstocks
2013
Abstract The carbohydrate degradation products have been examined, which are formed during the conventional kraft pulping of a softwood, hardwoods, bamboo, and wheat straw as well as soda and soda-anthraquinone pulping of wheat straw. The focus was on “volatile” acids such as formic and acetic acids and “nonvolatile” hydroxy monocarboxylic and dicarboxylic acids. The different consumption profiles were obtained for the charged alkali required for the neutralization of these aliphatic acids depending on the feedstock and the cooking method. The relative composition of the acid fraction in the black liquors of softwood and hardwood and nonwood feedstocks showed characteristic variations. Howe…
Assessment of Arundo donax Fibers for Oil Spill Recovery Applications
2019
In the last years, natural fibers are increasingly investigated as an oil recovery system in order to overcome the oil spillage phenomena, thus preserving environment and aquatic life. In particular, lignocellulose-based fibers have recently been employed with promising results. In such a context, the aim of this paper is to assess the oil sorption capability of natural fibers extracted from the stem of the giant reed Arundo donax L., a perennial rhizomatous grass belonging to the Poaceae family that grows naturally all around the world thanks to its ability to tolerate different climatic conditions. Sorption tests in several pollutants and water as a reference were carried out. The fibers …
The diagnosis and management of gastric cancer: Expert discussion and recommendations from the 12th ESMO/World Congress on Gastrointestinal Cancer, B…
2011
Well-recognized experts in the field of gastric cancer discussed during the 12th European Society Medical Oncology (ESMO)/World Congress Gastrointestinal Cancer (WCGIC) in Barcelona many important and controversial topics on the diagnosis and management of patients with gastric cancer. This article summarizes the recommendations and expert opinion on gastric cancer. It discusses and reflects on the regional differences in the incidence and care of gastric cancer, the definition of gastro-esophageal junction and its implication for treatment strategies and presents the latest recommendations in the staging and treatment of primary and metastatic gastric cancer. Recognition is given to the ne…
