Characterization of serpottas' stuccos by means of simultaneous thermal analysis: Preliminary results
2015
In this paper the Simultaneous Thermal Analysis (STA), i.e. thermogravimetric and differential thermal analysis, was used as a diagnostic tool to better understand the matter composition of some very valuable artworks the Serpottas’ stuccoes in Palermo. Particularly the STA was used in order to exclude the presence of an unusual calcium-bearing magnesium carbonate, and the thermal data were also used to quantify the magnesite to calcite ratio. The latter was investigated in order to evaluate the amount of magnesium in the lime used as binder as during 17th and 18th century in Sicily magnesium rich lime was indicated as the most valuable binder probably because this kind of lime has a higher…
La diversità degli animali domestici nelle isole circumsiciliane: un patrimonio scomparso prima di essere conosciuto
2018
In tutti gli studi che affrontano il tema della perdita della diversità animale allevata e vegetale coltivata in Sicilia non si fa cenno alla presenza di razze animali nelle isole circumsiciliane, ad eccezione dell’asino di Pantelleria. Recenti indagini hanno permesso di accertare una presenza storica, seppur limitata, di razze animali, oggi estinte, sulle isole parasicule. Inoltre i testi che trattano specificatamente di tali razze forniscono preziose informazioni sul passato uso agro-pastorale dei territori insulari e meritano pertanto un’adeguata valorizzazione. None of the studies dealing with the loss of Sicilian reared animal and cultivated plant diversity mentions the presence of ani…
Co-digestion of grass silage and cow manure in a CSTR by re-circulation of alkali treated solids of the digestate.
2008
Three laboratory, continuously stirred tank reactors (CSTRs) co-digesting grass silage and cow manure (forming 30% and 70% of substrate volatile solids (VS), respectively) were operated to evaluate the effects of re-circulating an alkali-treated and untreated solid fraction of the digestate back to the reactors. The CSTRs were operated at an organic loading rate (OLR) of 2 kg VS m(-3) day(-1) and hydraulic retention time (HRT) of 20 days with a semi-continuous mode of feeding. The feasibility of co-digestion with substrate VS containing 30% VS of crop was reinforced, resulting in average specific methane yield of about 180-185 1 CH4 kg(-1) VS. Re-circulation of the solid fraction of digesta…
Effects of Inter-cropping and a Herbicide on Management of Striga hermonthica on Sorghum
2017
Aims: The present work was undertaken to determine the effects of the herbicide chlorsulfuron and intercropping sorghum (cv.Wad-Ahmed) with cowpea (T100K-901-6 cv.) on S. hermonthica incidence and sorghum growth. Study Design: Randomized Complete Block Design (RCBD) with four replicates. Place and Duration of Study: A series of laboratory and greenhouse experiments was undertaken at the College of Agricultural Studies, Sudan University of Science and Technology (SUST) at Shambat, during the season 2013/2014. Methodology: Striga free or infested soil was placed in plastic pots (9 cm i .d) with perforations at the bottoms. Pots filled with Striga free soil (0 mg) were included as control for …
SimpleBIM: From full ifcOWL graphs to simplified building graphs
2016
International audience; Recent research in semantic web technologies for the built environment has resulted in several proposals to further improve information exchange among stakeholders from the domain. Most notable is the production of several OWL ontologies that allow to capture building data in RDF graphs. For example, an ifcOWL ontology allows to capture IFC data in an RDF graph. As the building data is now available in a semantic graph with an explicit formal basis, it can be restructured and simplified so that it more easily matches the different requirements associated with practical use case scenarios. In this paper, we investigate several proposals and technological approaches to…
Farmer-Herder Conflict in Africa: An Assessment of the Causes and Effects of the Sedentary Farmers-Fulani Herdsmen Conflict : A Case Study of the Ago…
2017
Master's thesis Global development and planning UT505 - University of Agder 2017 Violent conflicts, particularly farmer-herder conflicts have, for a long time, been a common feature of economic livelihood in West Africa (Bleach, 2004). This thesis explores the causes and the effects of farmer-Fulani herdsmen conflict, and the mitigation responses towards the conflict. The resource scarcity, eco-survivalism and social capital theories (Hommer-Dixon, 1999; Okoli, 2013; Bourdieu, 1986) serve as the main theoretical point of discussion for this study. Using Agogo in Ghana as a case study, the study empirically examines the reasons behind the movement of the Fulani herdsmen to Agogo, the causes …
Zróżnicowana integracja w Europie - źródła, mechanizmy, konsekwencje
2018
Kwestia zróżnicowanej integracji stanowi przedmiot ożywionej debaty zarówno wśród polityków, publicystów, jak również naukowców. Niewątpliwie zaawansowanej eksploracji wymaga jej pełne zrozumienie naukowe, dlatego celem niniejszego tekstu jest ustalenie źródeł i natury samego zjawiska zróżnicowanej integracji, przegląd głównych koncepcji analitycznych i wskazanie podstawowych mechanizmów nim rządzących. Tekst, metodą analizy deskryptywnej, oferuje również wnioski na temat potencjalnych konsekwencji postępujących procesów zróżnicowania integracji europejskiej.
Identification and evaluation of antimicrobial resistance of enterococci isolated from raw ewes’ and cows’ milk collected in western Sicily: a prelim…
2019
The present work was carried out to investigate the Antimicrobial Resistance (AMR) of enterococci isolated from raw ewes’ and cows’ milk. The samples were collected from eighteen semi-extensive dairy sheep and cow farms throughout western Sicily. Plate counts, carried out on Rapid Enterococcus Agar commonly used to detect food enterococci, revealed a maximal enterococcal concentration of approximately 4.58 Log Colony Forming Unit (CFU)/mL. Colonies were isolated and differentiated based on genetic analysis by Randomly Amplified Polymorphic DNA (RAPD)-PCR. Thirty-eight different strains were identified. Analysis by a species-specific multiplex PCR assay grouped the strains into three Enteroc…
Fatty Acids as Biomarkers of the Production Season of Caciocavallo Palermitano Cheese
2021
Simple Summary In the Mediterranean environment, climatic variability determines a discontinuity in the forage availability of pastures. Caciocavallo Palermitano is a cheese obtained from the milk of the Cinisara cattle breed, mainly raised on pasture. The present study investigated the fatty acid profile of cheeses produced in two typical farms in the four seasons of the year, with the aim of identifying specific fatty acids that can be used as biomarkers to discriminate the productions obtained in the different seasons, in order to economically enhance those seasonal productions that have better health characteristics. The results revealed the possibility of distinguishing spring producti…
