Ranke, Burckhardt und die "Orientalische Renaissance"
2021
The essay outlines Ranke's and Burckhardt's responses to the "Eastern Renaissance" triggered by Romanticism and late nineteenth-century culture. Main topics are the productive role of violence in history, the meaning of "sacrifice" and the danger of anonymity in metropolitan life. An important reference is found in a Quinet's book, which is used here as an undelying theme.
Reconstrucció del paisatge rural i urbà d'Almenara i La Llosa entre els segle XIII al XVI
2023
La tesi titulada «Reconstrucció del paisatge rural i urbà d'Almenara i La Llosa entre els segles XIII-XVI», aprofundeix en l'evolució del paisatge cultural d'ambdós municipis i l'estudi de la seua població. Amb la finalitat de valorar els béns culturals municipals d'aquest període i destacar-ne la rellevància i les funcions en el passat. Cosa que possibilita una millor acceptació en el manteniment i en el respecte d'aquests béns en la societat actual. El paisatge constitueix una realitat dinàmica, ja que és resultat de processos ambientals, socials i culturals que s'han succeït al llarg del temps en el territori. Aquests processos estan marcats per les maneres de vida, les polítiques, les a…
Hospitalistista apua viestinnän koordinointiin?

Lääkärin viestintä konkretisoi hoidon usein monimutkaisen kokonaisuuden potilaalle. Voisiko hospitalisti tukea potilaan ja hänen läheistensä osallistumista hoitokeskusteluun ja varmistaa hoitosuunnitelman ymmärtämistä? nonPeerReviewed
Biological Effects of New Hydraulic Materials on Human Periodontal Ligament Stem Cells.
2019
Background: The aim of this study was: to evaluate the biological properties of new hydraulic materials: Bio-C Repair and Bio-C Sealer. Methods: Periodontal ligament stem cells were exposed to several dilutions of Bio-C Repair and Bio-C Sealer. The ion release profile and pH were determined. Metabolic activity, cell migration and cell survival were assessed using the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT), wound-healing assays and Annexin assays, respectively. Cells were cultured in direct contact with the surface of each material. These were then analyzed via scanning electron microscopy (SEM) and energy dispersive X-ray (EDX). Statistical differences were ass…
Chemical Pretreatments of Wood Chips Prior to Alkaline Pulping - A Review of Pretreatment Alternatives, Chemical Aspects of the Resulting Liquors, an…
2015
The chemical industry is being forced to evaluate new strategies for more effective utilization of renewable feedstocks to diminish the use of fossil resources. In this literature review, the integration of both acidic and alkaline pretreatment phases of hardwood and softwood chips with chemical pulping is discussed. Depending on the pretreatment conditions, high-volume sulfur-free fractions with varying chemical compositions can be produced. In case of acidic pretreatments, the major products include carbohydrates (mono-, oligo-, and polysaccharides), whereas under alkaline (i.e., aqueous NaOH) pretreatment conditions, the sulfur-free fractions of aliphatic carboxylic acids, lignin, and ex…
Activated carbon from hydrolysis lignin: Effect of activation method on carbon properties
2022
This study presents the effects of different activation methods to produce activated carbon from the hydrolysis lignin. Pretreatment of the feedstock with common mineral acids (HCL, HNO3, and H3PO4), different steam rates for physical activation, and different chemical activating agents (ZnCl2, Na2CO3, and KOH) for chemical activation were investigated. The pretreated biomass was carbonized and activated in one-stage process and the surface characteristics, such as total pore volume, pore size distribution and specific surface area, were investigated. The results showed that the activated carbon surface properties were not greatly affected by acid pretreatment. Brunauer-Emmett-Teller (BET) …
Rapid one-step solvent-free acid-catalyzed mechanical depolymerization of pine sawdust to high-yield water-soluble sugars
2017
Abstract One-step absolute solvent-free acid-catalyzed mechanical depolymerization of pine sawdust (PSD) and commercially available α-cellulose to water-soluble sugars was carried out using ball milling. For comparison purposes, the commonly reported “solvent-free” mechanocatalytic depolymerization of lignocellulose method, which normally involves three steps (acid impregnation in solvent, vacuum drying, and mechanical depolymerization of lignocellulose), was performed. The 3,5-dinitrosalicylic acid (DNS) method was used to measure the total reducing sugar (TRS) of the obtained sugar solution, and major monosaccharides in the solution were analyzed by capillary electrophoresis (CE). More th…

Decorazione, illustrazione o metafora? Su un gruppo di terrecotte architettoniche dal sito di S. Biagio ad Agrigento
2014
At the end of the 19th cent. P. Orsi acquired for the Archaeological Museum of Syracuse a group of architectural terracottas said to come from Agrigentum, San Biagio area (on the SE slope of the Rupe Atenea). This lot, left quite unnoticed until now, consists of six antefixes of late 5th-early 3rd cent. B.C. Tarantine types with relief heads of Gorgo-Medusa, Pan, and Artemis Bendis, that can confirm the circulation of these products, known otherwhere in Sicily by a few specimens from Gela excavations and from surface finds. But the most noteworthy piece is a fragmentary clay sima with a lion head spout, dated around 280-70 B.C., that is particularly interesting both for the technique and fo…
