Comparison between the MHFEM formulation and a 2nd spatial order FV formulation of the linear groundwater flow problem
2008
Mixed and Mixed Hybrid Finite Elements (MHFE) methods have been widely used in the last decade for simulation of groundwater flow problem, petroleum reservoir problems, potential flow problems, etc. The main advantage of these methods is that, unlike the classical Galerkin approach, they guarantee local and global mass balance, as well the flux continuity between inter-element sides. The simple shape of the control volume, where the mass conservation is satisfied, makes also easier to couple this technique with a Finite Volume technique in the time splitting approach for the solution of advection-dispersion problems. In the present paper a new second spatial approximation order Finite Volum…
Reproduction of Baltic cod, Gadus morhua (Actinopterygii: Gadiformes: Gadidae), in the Gotland Basin: Causes of annual variability
2015
Background. The Gotland Basin spawning ground is one of three main spawning areas of Baltic cod, Gadus morhua Linnaeus, 1758. The threshold water parameters for cod development are the salinity exceeding 11‰ and the oxygen level above 2 mL· L–1. Such conditions are only present when the 11‰ isohaline is above the 2 mL· L–1 isooxygen. In such situation the water volume between the isolines is called the “suitable reproduction volume”. When the position of the isolines is reversed, the salinity and the oxygen level of the water layer demarcated by them are below the required thresholds and as such the water is unsuitable for the cod development. We refer to it as the “unsuitable reproduction …
Educational or emotional languages? An interactive experiment with the Lucanian flora (S-Italy)
2010
In the frame of dissemination activities for a still-in-progress work on the Sites of Community Importance (see EU Directive 92/43) of Basilicata (a region of Southern Italy), an interactive tool (IIT) for the identification of vascular plants growing there has been illustrated to two groups of people, following two different approaches: one focused on textual parts and on scientific accuracy, the other on images and on the visual comparison of different objects. The reactions were measured in terms of number of accesses to the IIT, elapsed time from the demonstration to the first individual access, and number of queries in the first week after the IIT was distributed. The most clicked opti…
The heterogeneity of the Mexican lithospheric mantle: Clues from noble gas and CO2 isotopes in fluid inclusions
2022
The abundance of mantle-derived rocks and lavas, in combination with its tectonic evolution, render Mexico a perfect laboratory to investigate the chemical and the isotopic heterogeneity of the lithospheric mantle. New data on the composition of noble gases and CO2in Mexican mantle xenoliths and lavas is reported. Our samples consist of six ultramafic nodules from the Durango Volcanic Field (DVF) and the San Quintin Volcanic Field (SQVF), monogenetic complexes belonging to the Mexican Basin and Range province; and four lavas from the Sierra Chichinautzin (SCN), a Quaternary monogenetic volcanic field located in the Mexican volcanic arc. Ne and Ar isotopes in fluid inclusions reveal mixing b…
Evaluation of holy basil mouthwash as an adjunctive plaque control agent in a four day plaque regrowth model
2014
Objectives: Various antibacterial and antiplaque agents are used in chemical plaque control but none are without their shortcomings. Chlorhexidine considered a gold standard, also has an array of side effects. To overcome these, numerous herbal extracts have been tried and tested and one among them is holy basil. The present study evaluated the antibacterial efficacy of holy basil in vitro against some periodontopathogens and its antiplaque ef fect in vivo. Study Design: Thirty periodontally healthy volunteers were randomly divided into three groups and refrained from all mechanical oral hygiene measures for 4 days and used one of the randomly assigned mouthwash (1- chlor - hexidine; 2- hol…
Essential Oil Composition of the Aerial Parts of FiveOcimumspecies from Western India
2015
AbstractChemical composition of the essential oils of five Ocimum species namely Ocimum tenuiflorum syn Ocimum sanctum L. (green and purple), Ocimum kilimandscharicum Guerke, Ocimum viride Willd, Ocimum basilicum L. and Ocimum gratissimum L., obtained by a hydrodistillation was determined by GC and GC-MS. A total of one hundred three compounds were identified in the oils of five Ocimum species, of which fifteen compounds were found to be major (5.0–81.8 %) compounds. Analysis of Ocimum viride oil showed the highest amount of eugenol (81.8 %) among species besides germacrene D (7.0 %) and cis-ocimene (4.1 %). Ocimum tenuiflorum green and Ocimum tenuiflorum purple were found contain eugenol (…
The Influence of Scalded Flour, Fermentation, and Plants Belonging to Lamiaceae Family on the Wheat Bread Quality and Acrylamide Content
2018
The aim of this study was to investigate the influence of additives such as plants belonging to Lamiaceaefamily (Thymus vulgaris, Carum carvi, Origanum vulgare, Ocimum basilicum, and Coriandrum sativum), scalded flour (SF) or scalded flour fermented with Lactobacillus plantarumLUHS135 (SFFLp) on the quality and acrylamide formation in wheat bread. The formation of acrylamide and bread quality significantly depended on the king of plants used and the amount of SF and SFFLp used. The additives of T. vulgarisand SF increased the content of acrylamide by 3.4-fold in comparison with bread prepared without SF, whereas the addition of SFFLp significantly reduced the content of acrylamide in bread,…
Investigation of the hygienic safety of aromatic plants cultivated in soil contaminated with Listeria monocytogenes
2012
Abstract The present work was undertaken to investigate the survival of Listeria monocytogenes ATCC 19114T in soil during the whole crop cycle of rocket (Eruca sativa Mill.) and basil (Ocimum basilicum L.), to monitor its transfer to the leaves, and to evaluate its viability at harvest. To this purpose, the soil was N–P–K fertilized and four trials, obtained with different combinations of soil treatment, listerial inoculums and seed planting, were followed for each aromatic plant. Soil was weekly investigated for total microbial counts and L. monocytogenes evolution. At the starting time, un-inoculated autoclaved soil showed a limited microbial load (103 CFU g dw−1), while un-inoculated non…
Application of Potassium Ion Impregnated Titanium Dioxide as Nanocatalyst for Transesterification of Linseed Oil
2018
The current work comprises the investigation of biodiesel production from linseed oil using TiO2 and a potassium L-tartrate monobasic (C4H5KO6)-modified TiO2 nanocatalyst. Different amounts of C4H5KO6 were considered for TiO2 modification. The nanocatalyst TiO2–0.5C4H5KO6 (1:0.5 molar ratio) showed the best conversion rate for biodiesel production. The nanocatalyst was characterized by FTIR, XRD, TEM, BET, and XPS, and the Hammett indicator–benzenecarboxylic acid titration method was used for basicity measurement. The biodiesel was characterized by GC-MS and 1H and 13C NMR. Furthermore, the optimum reaction parameters for transesterification reaction were analyzed, and the yield was determi…
El mito de orfeo y euridice en los origenes del melodrama
2019
En el nacimiento de la ópera (el melodrama) el tema elegido de manera mayoritaria fue el del mito de Orfeo, el semidiós cantor porque con este personaje no se rompía la verosimilitud al representar obras totalmente cantadas. Aunque su presencia en el género operístico de los orígenes se debe también a otros factores importantes. La complejidad del personaje, de su historia y características que han hecho de Orfeo un personaje literario, cuya presencia destaca en diferentes obras de autores de todos los tiempos. En la literatura italiana, la influencia de Virgilio, que nos presenta a Orfeo en las Geórgicas, y de Ovidio y sus Metamorfosis fue determinante, pero además el personaje de Orfeo es…
