    Medievalism in contemporary Fantasy: a new Species of Romance

    Get PDF
    Contemporary fantasists are often inspired by the texts from and with medieval context. This paper taps into Horace Walpoleā€™s principles revealed in the preface to The Castle of Otranto to show that the works of medieval fantasy and contemporary fantasy subgenres written in 20th and 21st centuries have a lot in common with Walpoleā€™s recipe for creating ā€˜a new species of romanceā€™. When considered from the present time, the Medieval period can be seen as being halfway between fantasy and reality, in a blurry area where the two overlap, and contemporary fantasists use this trait to build their fictional worlds as effective reverberators of universal themes that remain interesting, appealing and worth repeating

    Characterization of trypsin-like enzymes from the midgut of Morimus funereus (Coleoptera: Cerambycidae) larvae

    Get PDF
    The pH along the midgut of M. funereus larvae had different values, being acidic in the anterior section and basic in the middle and posterior sections. Elastase- and chymotrypsin-like activities were highest in the middle, low in the anterior, and negligible in the posterior section of the midgut. Trypsin-like activities were detected along the whole midgut, with more than 90% of activity in the anterior section. The level of elastase- and chymotrypsin-like activity was very low compared to trypsin-like activity. In the anterior section of the midgut, two isoforms of trypsin-like enzymes were found, both being basic and almost completely inhibited by benzamidine

    Ī±-Amylase isoforms of Cerambyx cerdo larvae from the wild (ML and SL) and reared in the laboratory (ADL) were compared. Three amylase isoforms were presented in the SL and ML extracts while two isoforms were presented in the ADL according to zymogram after isoelectric focusing (IEF). All C. cerdo amylase isoforms were acidic proteins (pI < 3.5). Seven amylase isoforms (ACC 1-7) from the midgut of C. cerdo larvae were found in the ML midgut extract, six in the SL extract, and four in the ADL extract according to native PAGE zymogram. The ADL amylase had the highest activity. All crude midgut extracts of C. cerdo larvae were fractionated on a Superose 12 HR column. The molecular mass of the ACC was estimated to be 34 kDa.Upoređene su izoforme Ī±-amilaze larvi Cerambyx cerdo sakupljenih iz prirode (ML i SL) i gajenih na veÅ”tačkoj podlozi u laboratoriji (ADL). Zimogramskom detekcijom posle IEF-a po tri izoforme su detektovane u ML i SL ekstraktima, a u ADL dve izoforme. Sve amilazne izoforme iz C. cerdo su bile kisele (pI < 3.5). Zimogramskom detekcijom posle nativne elektroforeze sedam izoformi je detektovano u ML ekstraktu, Å”est u SL ekstraktu i četiri u ADL ekstraktu. Najveća amilazna aktivnost je detektovana u ADL ekstraktu. Svi ekstrakti srednjih creva larvi C. cerdo su frakcionisani na koloni Superose 12 HR. Molekulska masa ACC-a je bila 34 kDa.Projekat ministarstva br. 142026

    Cilj ovog rada je da se ispita uticaj gama i X zračenja na brzinu odziva komercijalnih CITEL i SIEMENS gasnih odvodnika prenapona. Pokazano je da oba tipa zračenja dovode do promene impulsne karakteristike odvodnika.. Dobijeni rezultati pokazuju da su u polju gama zračenja otporniji odvodnici firme CITEL, a u polju X zračenja SIEMENS odvodnici.The aim of this paper is to examine the influence of Ī³ and X radiation to response time of some commercial gas filled surge arresters. We found that both radiations have significant influence on gas filled surge arresters pulse characteristic. The obtained results show that the optimal solution in gamma radiation field was CITEL components, while in X radiation field was better to use SIEMENS components.XXIV Simpozijum DruÅ”tva za zaÅ”titu od zračenja Srbije i Crne Gore, Zlatibor, 3-5. oktobar 2007

    Structural characterisation of starch based edible films with essential oil addition

    Get PDF
    Present study investigated structure of starch based edible films with essential oil addition. Films were obtained from water solutions containing gelatinized modified starch, polyol, guar-xantan gum modified mixture and essential oil by casting it on a Petri dish and evaporating at room temperature for 72h. Both, glycerol and guar-xantan modified mixture, had role to improve film flexibility and enable better film folding and handling. Two sample groups were obtained: starch based edible films with black cumin oil addition and starch based edible films with black pepper oil addition. Both essential oils were added in three different concentrations. Starch based edible film without essential oil addition was used as blank shot. Structural properties were determined by analyzing spectra obtained by FT-IR Spectrometer in the spectral range of 4000ā€“400 cmāˆ’1 with a 4.0 cmāˆ’1 resolution. Software Omnic 8.1. and TQ Analyst were used to operate the FTIR spectrometer, collect and present all the data. Results pointed to quantitative law dependency between added amount of essential oils and spectra absorption values for both sample groups and FTIR spectra were used to calculate coefficient of correlation

    One-dimensional charged kaon femtoscopy in p-Pb collisions at āˆšsNN = 5.02 TeV

    Get PDF
    The correlations of identical charged kaons were measured in p-Pb collisions at āˆšsNN=5.02 TeV by the ALICE experiment at the LHC. The femtoscopic invariant radii and correlation strengths were extracted from one-dimensional kaon correlation functions and were compared with those obtained in pp and Pb-Pb collisions at āˆšs=7 TeV and āˆšsNN=2.76 TeV, respectively. The presented results also complement the identical-pion femtoscopic data published by the ALICE collaboration. The extracted radii increase with increasing charged-particle multiplicity and decrease with increasing pair transverse momentum. At comparable multiplicities, the radii measured in p-Pb collisions are found to be close to those observed in pp collisions. The obtained femtoscopic parameters are reproduced by the EPOS 3 hadronic interaction model and disfavor models with large initial size or strong collective expansion at low multiplicities

    Exploration of jet substructure using iterative declustering in pp and Pbā€“Pb collisions at LHC energies

    Zhe ALICE collaboration at the CERN LHC reports novel measurements of jet substructure in pp collisions at āˆšs= 7 TeV and central Pb-Pb collisions at āˆšsNN = 2.76 TeV. Jet substructure of track-based jets is explored via iterative declustering and grooming techniques. We present the measurement of the momentum sharing of two-prong substructure exposed via grooming, th

    Measurement of Ī„(1S) Elliptic Flow at Forward Rapidity in Pb-Pb Collisions at āˆšsNN=5.02ā€‰ā€‰TeV

    The first measurement of the Ī„(1S) elliptic flow coefficient (v2) is performed at forward rapidity (2.5 &lt; y &lt; 4) in Pbā€“Pb collisions at āˆšsNN=5.02 TeV with the ALICE detector at the LHC. The results are obtained with the scalar product method and are reported as a function of transverse momentum (pT) up to 15 GeV/c in the 5%ā€“60% centrality interval. The measured Ī„(1S)v2 is consistent with 0 and with the small positive values predicted by transport models within uncertainties. The v2 coefficient in 2 &lt; pT &lt; 15 GeV/c is lower than that of inclusive J/Ļˆ mesons in the same pT interval by 2.6 standard deviations. These results, combined with earlier suppression measurements, are in agreement with a scenario in which the Ī„(1S) production in Pbā€“Pb collisions at LHC energies is dominated by dissociation limited to the early stage of the collision, whereas in the J/Ļˆ case there is substantial experimental evidence of an additional regeneration component

    The measurement of the production of prompt D0, D+, D*+, and D+S mesons in protonā€“lead (pā€“Pb) collisions at the centre-of-mass energy per nucleon pair of āˆšsNN = 5.02 TeV, with an integrated luminosity of 292 Ā± 11 Ī¼bāˆ’1, are reported. Differential production cross sections are measured at mid-rapidity (āˆ’0.96 &lt; ycms&lt; 0.04) as a function of transverse momentum (pT) in the intervals 0 &lt; pT&lt; 36 GeV/c for D0, 1 &lt; pT&lt; 36 GeV/c for D+ and D*+, and 2 &lt; pT&lt; 24 GeV/c for D+ mesons. For each species, the nuclear modification factor RpPb is calculated as a function of pT using a proton-proton (pp) ref- erence measured at the same collision energy. The results are compatible with unity in the whole pT range. The average of the non-strange D mesons RpPb is compared with theoretical model predictions that include initial-state effects and parton transport model predictions. The pT dependence of the D0, D+, and D*+ nuclear modification factors is also reported in the interval 1 &lt; pT&lt; 36 GeV/c as a function of the collision centrality, and the central-to-peripheral ratios are computed from the D-meson yields measured in different centrality classes. The results are further compared with charged-particle measurements and a similar trend is observed in all the centrality classes. The ratios of the pT-differential cross sections of D0, D+, D*+, and D+S mesons are also reported. The D+S and D+ yields are compared as a function of the charged-particle multiplicity for several pT intervals. No modification in the relative abundances of the four species is observed with respect to pp collisions within the statistical and systematic uncertainties
