Preliminary photochemical studies of fluorene in various aqueous media
2014
- The current study investigates the direct photochemical degradation of aqueous fluorene with the aid of a 125W polychromatic medium, pressure Hg lamp. The purpose was to test the effectiveness of the lamp in irradiation using fluorene spiked solution as substrate. A 700 ml volume of fluorene solution of 0.002 mg/l was irradiated batch-wise at 1, 3, 6, 12, 18, 24 and 48 h. The amount of fluorene removal was studied for fluorene solutions prepared from , neutral (distilled water), acidic (by adjusting pH with hydrochloric acid, HCl), basic (by adjusting pH with sodium hydroxide, NaOH) and saline (addition of sodium chloride, NaCl) solutions and there was 95.95, 92.35, 96.65 and 97.15 % remo…
La transformación de la cultura clásica en el s.IV: el caso de Filastrio de Brescia
2018
Resumen: La obra de Filastrio de Brescia, Diversarum hereseon liber, compuesta a finales del siglo IV (380-90), se inserta en el género de la heresiología o catálogos adversus omnes haereses. De entre las 156 «herejías» que enumera este autor en su obra, además de los ya más que conocidos herejes o grupos de herejes como Simón mago, Valentinianos y otros, dedica un elevado número de entradas heréticas a refutar la tradición clásica. Analizamos en el presente trabajo la actitud de este clérigo ante los saberes clásicos. Centraremos nuestra atención en la transformación de aquellos conocimientos clásicos relacionados con la cosmografía, etnografía e historia en unos puramente bíblicos. Abstra…
Hacia la convergencia de las estadísticas de las finanzas públicas y la contabilidad pública en Europa a nivel central y local
2018
[EN] The main aim of this paper is to study the convergence between micro and macro systems of government accounting information, looking to contribute to the analysis of accounting harmonization process in the EU, as a tool to improve the comparability of financial, budgetary, and aggregated statistical reports, in order to improve social, political and economic decision-making and accountability. All this is obviously located in the current context of the EU, with a high degree of harmonization of accounting standards between the International Public Sector Accounting Standards (IPSAS), and those applied for the preparation of national accounts, ruled by European System of National and Re…
On the italian debate concerning “Economia Aziendale”. The recent discovery of a manuscript by Emilio Ravenna (1930)
2016
The paper relies upon the recent discovery of the textbook of Accounting adopted in Palermo’s High Business School (the ‘ancestor’ of the Faculty of ‘Economics & Business’, founded after in 1936), just in its first years of opening (academic year 1930-31). It is a printed manuscript. This book was written by the local professor of Accounting, Emilio Ravenna, who operated in Sicily between the last decades of XIX century and the firstones of XX one, commonly considered (Guzzo, 2003) an intermediate scholar between the ‘Venetian’ (Besta) and ‘Tuscan’ (Cerboni) Italian Schools, adhering to the former for the accounting method and to the latter for the general theory of administrative funct…
Ticket to spawn: Combining economic and genetic data to evaluate the effect of climate and demographic structure on spawning distribution in Atlantic…
2019
Abstract Climate warming and harvesting affect the dynamics of species across the globe through a multitude of mechanisms, including distribution changes. In fish, migrations to and distribution on spawning grounds are likely influenced by both climate warming and harvesting. The Northeast Arctic (NEA) cod (Gadus morhua) performs seasonal migrations from its feeding grounds in the Barents Sea to spawning grounds along the Norwegian coast. The distribution of cod between the spawning grounds has historically changed at decadal scales, mainly due to variable use of the northern and southern margins of the spawning area. Based on historical landing records, two major hypotheses have been put f…
Chemistry of Desiccant Properties of Carbohydrate Polymers as Studied by Near-Infrared Spectroscopy
2013
Published version of an article in the journal: Industrial and Engineering Chemistry Research. Also available from the publisher at: http://dx.doi.org/10.1021/ie302199k The combination frequency of water molecule in near-infrared spectroscopy is very useful for studying water molecular adsorption on solid surfaces. The absorption is purely from water molecules, and the variation in the absorption bands reflects the change in the environment of the water molecules on a surface. This variation, in turn, reflects the nature of the functional groups on the surface. Recently, Christy used this information in combination with second-derivative techniques to probe the surface of hydrothermally tre…
Ammonoids and quantitative biochronology - A unitary association perspective
2015
Ammonoid evolutionary changes have long been recognized to be excellent time markers. They are the major macrofossil group to date and correlate Paleozoic and Mesozoic marine strata. Originations and extinctions of ammonoid species are commonly used to define GSSPs and build high resolution biozonations. Biochronology is now an advanced field with the recent development of computerized, quantitative methods yielding robust biochronological schemes. It has been demonstrated that such quantitative biochronological methods are very efficient to resolve (often complex) biostratigraphic contradictions and produce accurate and high resolution biozonations, thus enabling precise dating and correla…
The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …
2021
The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…
Near infrared spectroscopic study on the adsorption of methanol on silica gel
2013
Author's version of an article in the journal: Advanced Materials Research. Also available from the publisher at: http://dx.doi.org/10.4028/www.scientific.net/AMR.650.150 The silanol groups on Silica gel surface are sites for adsorption of polar molecules. Alcohols and other polar molecules are easily adsorbed by forming hydrogen bondings with OH groups on silica gel surface. A study on the adsorption of methanol on silica gel was carried out by using NIR spectroscopy in combination with ssecond derivative techniques. Four of the well characterised silica gel samples were used in this study. Each of the silica gel (0.25g) samples with different surface areas and silanol number was pressed i…
A new selenosteid placoderm from the Late Devonian of the eastern Anti-Atlas (Morocco) with preserved body outline and its ecomorphology
2022
Placoderms are an extinct group of early jawed vertebrates that play a key role in understanding the evolution of the gnathostome body plan, including the origin of novelties such as jaws, teeth, and pelvic fins. As placoderms have a poorly ossified axial skeleton, preservation of the mainly cartilaginous axial and fin elements is extremely rare, contrary to the heavily mineralized bones of the skull and thoracic armor. Therefore, the gross anatomy of the animals and body shape is only known from a few taxa, and reconstructions of the swimming function and ecology are speculative. Here, we describe articulated specimens preserving skull roofs, shoulder girdles, most fins, and body outlines …
