2008
Il volume raccoglie i contributi alla Giornata di studi svolta a Caltanissetta il 29 giugno 2007; Responsabile Scientifico Maria Luisa Germanà. La pubblicazione è stata finanziata dalla DISMAT (Laboratorio per la sperimentazione sulle strutture e sui materiali da costruzione) con sede a Canicattì (AG). I contenuti sono articolati nelle seguenti parti: - Contributi generali; - La terra cruda nei contesti antichi: problemi conoscitivi; La terra cruda nei contesti antichi: problemi conservativi; - La terra cruda nelle costruzioni: potenzialità e limiti nell'impiego odierno.
A bacterial metabolite, trimethylamine N-oxide, disrupts the hemostasis balance in human primary endothelial cells but no coagulopathy in mice
2019
: The gut microbial metabolite, trimethylamine N-oxide (TMAO), was previously reported to induce platelet hypersensitivity, which leads to thrombotic risk. However, the molecular mechanism underlying the effects of TMAO on endothelial cells (EC), which is the primary vessel wall contact with the lumen, remains unclear. Here, we investigated the impact of TMAO on procoagulant activity (PCA) in EC and mice, for a possible link between microbiota and coagulation. To test the PCA of TMAO in EC, we performed one-stage clotting assays and converted into PCA. Antitissue factor (TF) antibody was used to test the TF role in PCA. Quantitative PCR was performed to measure the TF, thrombomodulin, IL-6,…
Associations of Maternal Cell-Phone Use During Pregnancy With Pregnancy Duration and Fetal Growth in 4 Birth Cohorts
2019
Results from studies evaluating potential effects of prenatal exposure to radio-frequency electromagnetic fields from cell phones on birth outcomes have been inconsistent. Using data on 55,507 pregnant women and their children from Denmark (1996-2002), the Netherlands (2003-2004), Spain (2003-2008), and South Korea (2006-2011), we explored whether maternal cell-phone use was associated with pregnancy duration and fetal growth. On the basis of self-reported number of cell-phone calls per day, exposure was grouped as none, low (referent), intermediate, or high. We examined pregnancy duration (gestational age at birth, preterm/postterm birth), fetal growth (birth weight ratio, small/large size…
Copper, iron, and zinc contents in human milk during the first three months of lactation: A longitudinal study
2000
The aim of the study has been to analyze the evolution of copper, iron, and zinc contents in human milk, from colostrum to the third postpartum month, following a longitudinal design, under specific conditions of sample collection and to apply an analytical procedure previously optimized to reduce any variation outside physiological lactation. The copper, iron, and zinc concentrations in 144 milk samples from 39 healthy puerpera women, were analyzed in five stages by flame atomic absorption spectrometry, following a standardized protocol. Copper presented a gradual decrease from 0.38 mg/L to 0.19 mg/L by the 90th day; the particular analysis from colostrum to transitional milk manifested th…
Bioloģiski aktīvo vielu saturs ķirbjos
2022
Bioloģiski aktīvo vielu saturs ķirbjos. Matajeva L. S., zinātniskā vadītāja Dr. ķīm., asoc. prof. Jākobsone I. Bakalaura darbs 43 lapās, satur 9 attēlus, 15 tabulas, 3 pielikumus un 30 literatūras avotus. Latviešu valodā. Bakalaura darba mērķis ir noskaidrot bioloģiski aktīvo vielu saturu dažādu sugu un šķirņu Latvijā audzētos ķirbjos, kā arī to satura izmaiņas, uzglabājot tos saldētā un žāvētā veidā. Bakalaura darba ietvaros gravimetriski tika noteikts sausnes saturs, tieši reducējošo cukuru un saharozes daudzums ar Lufa – Šorla (Luff – Schoorl) metodi, kopējo fenola savienojumu saturs ar Folina – Čikolto (Folin – Ciocalteu) metodi, spektrofotometriski β-karotīna saturs ar modificēto I.

Recyclable and Light-Adaptive Vitrimer-Based Nacre-Mimetic Nanocomposites.
2021
Nacre's natural design consists of a perfect hierarchical assembly that resembles a brick-and-mortar structure with synergistic stiffness and toughness. The field of bioinspired materials often provides attractive architecture and engineering pathways which allow to explore outstanding property areas. However, the study of nacre-mimetic materials should not be limited to the design of its architecture but ought to include the understanding, operation, and improvement of internal interactions between their components. Here, we introduce a vitrimer prepolymer system that, once integrated into the nacre-mimetic nanocomposites, cures and cross-links with the presence of Lewis acid catalyst and …
Propuesta de un método de evaluación del patrimonio cultural y su aplicación en Cortes de Pallás (Valencia)
2020
Las áreas rurales han experimentado significativas transformaciones socioeconómicas en las últimas décadas, en las cuales ha sido común la competencia de los ámbitos urbanos. Actualmente constituyen espacios multifuncionales caracterizados por el desempeño de nuevas actividades, donde el patrimonio se configura como un recurso esencial en las estrategias de desarrollo territorial (local). No obstante, el diseño de proyectos de valorización requiere la identificación del valor de cada bien. El propósito del estudio es la propuesta de un método de evaluación del patrimonio cultural, conformado por tres sistemas específicos que permiten cuantificar el interés patrimonial de los bienes inmueble…
Fazioni e popolo in una provincia del dominio pontificio fra XIII e XIV secolo
2021
Between the 13th and 14th centuries, a number of cities in the inchoative papal state experimented a system of self-government that allowed the Guelph and Ghibelline factions, formally represented in those same bodies on an equal footing, to work alongside the more strictly communal magistracies. The case of Todi is rather well known, given the role that Bartolo da Sassoferrato assigns to it in his Tractatus de guelphis et gebellinis (ca. 1350), but current research has already ascertained that this political tradition appeared at least around 1260. Some evidence can suggest, however, that some form of integration of factions into the local institutional framework was possible elsewhere, an…
La crisis del modelo tradicional de regadíos del interior valenciano. El caso de Cortes de Pallás: paisajes del agua y patrimonio cultural
2020
Los sistemas tradicionales de regadío forman un legado que se manifiesta mediante lo que conocemos como paisaje y patrimonio del agua. En las áreas del interior valenciano se experimentan disfunciones socioeconómicas que se evidencian paisajísticamente. A partir del análisis en profundidad de un caso de estudio como es la huerta de Cortes de Pallás, en el sector septentrional del macizo del Caroig, se valora si los procesos en ella identificados explican las dinámicas de crisis de los regadíos históricos del interior. El abandono de una parte destacada de las parcelas ha sido una práctica común, aun manteniéndose su morfología y una red de acequias que sigue en funcionamiento. Els sistemes …
Piccola ontologia della relazione di coppia
2020
Si parla del nostro tempo come di un’epoca post-familiare, per intendere il declino o – per alcuni – il tramonto della famiglia nelle società occidentali della tarda modernità. Il fenomeno, a ben vedere, appare molto complesso e il «grande trambusto» non riguarda solo la vita familiare, porta anche a parlare di «sensibile mutamento» della relazione di coppia e di «evaporazione» dei rapporti genitoriali, in particolare della figura del padre. Per poter interpretare adeguatamente il cambiamento e la complessità, qualche autore ha proposto di cercarne la radice in una «sostanziale trasformazione dell’intimità»: una vera e propria «metamorfosi» del modo di sentire e di vivere l’affettività; asp…
