Strength prediction of a triaxially braided composite
2011
The architecture of textile reinforcement affects the deformation and failure behavior of the textile reinforced composites. This paper presents an approximate method that incorporates the in-plane periodic meso structure of the textile composite in finite element models. In this approach, the representative unit cell (RUC) of a textile composite is divided into sub-cells. Instead of obtaining a homogeneous equivalent, these sub-cells are idealized and represented with laminates of different layups using shell elements. In this way, an RUC can be constructed with a small number of elements. This method holds the promise of creating a textile composite FE model with an improved accuracy with…
The Nuclear Mean Field and Many-Nucleon Configurations
2007
After the two preceding chapters, throughout impregnated with messy-looking, though necessary mathematics, we are finally entering the realm of basic concepts of nuclear structure physics. While the preceding chapters may have been a shock to the reader not familiar with the fine details of angular momentum coupling, the present chapter should offer a soothing soft landing to the basic philosophy behind the nuclear shell model, namely the nuclear mean field.
Solid state 13C-NMR methodology for the cellulose composition studies of the shells of Prunus dulcis and their derived cellulosic materials.
2020
Lignocellulosic fibers and microcellulose have been obtained by simple alkaline treatment from softwood al- mond shells. In particular, the Prunus dulcis Miller (D.A.) Webb. was considered as a agro industrial waste largely available in southern Italy. The materials before and after purification have been characterized by 13C CPMAS NMR spectroscopy methodology. A proper data analysis provided the relative composition of lignin and holo- cellulose at each purification step and the results were compared with thermogravimetric analysis and FT-IR. To value the possibility of using this material in a circular economy framework, the fibrous cellulosic material was used to manufacture a handmade c…
Frankenstein or the modern theurgist, the reception of Hermetic magic in Mary Shelley’s work
2017
This work considers the relationship between the novel Frankenstein; or, The Modern Prometheus and nineteenth-century esotericism with Hermeticism and its magical practices. We will focus on the influence of theurgy, a very popular magical-religious practice among the Neoplatonic movements of the first centuries of our era. In its Hermetic form, the art of animating statues through the attraction of their internal divine powers stands out. On the one hand, we will present an analysis of the path that this unique practice follows until it reaches Frankenstein. On the other hand, we will deal with the reception of the motive in this work.
Deep conservation of bivalve nacre proteins highlighted by shell matrix proteomics of the Unionoida Elliptio complanata and Villosa lienosa.
2016
The formation of the molluscan shell nacre is regulated to a large extent by a matrix of extracellular macromolecules that are secreted by the shell-forming tissue, the mantle. This so-called ‘calcifying matrix’ is a complex mixture of proteins, glycoproteins and polysaccharides that is assembled and occluded within the mineral phase during the calcification process. Better molecular-level characterization of the substances that regulate nacre formation is still required. Notable advances in expressed tag sequencing of freshwater mussels, such as Elliptio complanata and Villosa lienosa , provide a pre-requisite to further characterize bivalve nacre proteins by a proteomic approach. In this…
Electronic structure and properties of MAu and MOH, where M = Tl and Nh: New data
2018
Abstract Properties of the MAu and MOH (M = Tl and element 113, Nh) molecules were calculated using the 2c-DFT method. The obtained data are needed for evaluation of reactivity of Nh studied by gas-phase chromatography experiments. Results show that Nh should be less reactive (or more volatile) than Tl, both with respect to gold and the hydroxyl group. The reason for that are strong relativistic effects on the valence 7s and 7p electron shells. In difference to the atoms, NhOH may be less volatile than TlOH due to its larger both dipole moment and anisotropic polarizability.
A voyage to Vardø - A scientific account of an unscientific expedition
2013
After the “Venus Transit Conference” that took place at the University of Tromsø from June 2 to June 3, 2012, participants were given the opportunity to either stay in Tromsø until the night of June 5–6, or to participate in a voyage to Finnmark, where the historical sites Vardø, Hammerfest, and the North Cape were to be visited. This voyage culminated in the observation of the 2012 transit of Venus at Vardø. This paper gives a detailed account of this voyage that lasted from June 3 to June 6, and emphasizes the historical, scientific, philosophical, educational and cultural involvement of the participants of the voyage and of the local population. The paper concludes with reflections on th…
Genetic relatedness among environmental, clinical, and diseased-eel Vibrio vulnificus isolates from different geographic regions by ribotyping and ra…
1998
ABSTRACT Genetic relationships among 132 strains of Vibrio vulnificus (clinical, environmental, and diseased-eel isolates from different geographic origins, as well as seawater and shellfish isolates from the western Mediterranean coast, including reference strains) were analyzed by random amplified polymorphic DNA (RAPD) PCR. Results were validated by ribotyping. For ribotyping, DNAs were digested with Kpn I and hybridized with an oligonucleotide probe complementary to a highly conserved sequence in the 23S rRNA gene. Random amplification of DNA was performed with M13 and T3 universal primers. The comparison between ribotyping and RAPD PCR revealed an overall agreement regarding the high l…
A comparison of strategies for the detection and recovery of Vibrio vulnificus from marine samples of the Western Mediterranean coast
1998
Summary We have compared the effectiveness of culture-based methods and a DNA-based method for the detection, of Vibrio vulnificus from seawater and three types of shellfish collected from the coastal waters of Valencia, Spain. For culture-based method, we used two selective media, thiosulphate-citrate-bile salts-sucrose (TCBS), and cellobiose-polymyxin B-colistin (CPC) agars with and without previous enrichment in alkaline-saline-peptone-water (APWS). Presumptive colonies were confirmed as V. vulnificus by the polymerase chain reaction (PCR) using previously described 23S rRNA V. vulficus -specific sequences as primers (Dvu 9V and Dvu 45R). Direct detection was accomplished by a nested-PCR…
Karyological observations on plant taxa endemic to the Balearic Islands
2007
Mitotic chromosome numbers are reported from 35 vascular plant taxa endemic to the Balearic Islands that are poorly known cytogenetically. The chromosome numbers of Chaenorhinum rodriguezii (2n = 14), Coristospermum huteri (2n = 22), Carduus ibicensis (2n = 26), Filago petro-ianii (2n = 26), Ononis crispa ssp. zschackei (2n = 30), and Ophrys bertolonii ssp. balearica (2n = 36) were determined for the first time. New chromosome numbers are reported in Pimpinella bicknellii (2n = 22), Calamintha rouyana (2n = 46), Vicia bifoliolata (2n = 14), and Teucrium asiaticum (2n = 30). A new diploid cytotype (2n = 16) was found in Ranunculus paludosus ssp. barceloi, which is restricted to populations f…
