Nine Dubious “Dead Sea Scrolls” Fragments from the Twenty-First Century

2017

Abstract In 2002 new “Dead Sea Scrolls” fragments began to appear on the antiquities market, most of them through the Kando family. In this article we will present evidence that nine of these Dead Sea Scrolls-like fragments are modern forgeries.

Structure features and phase behaviour of amphiphilic N-tetradecyl-β-hydroxy-propionic acid amide monolayers

1997

Abstract Two phase transitions of N-tetradecyl-β-hydroxy-propionic acid amide monolayers at the air/water interface were studied by means of pressure/surface area ( π A ) isotherms, Brewster angle microscopy (BAM) and synchrotron X-ray grazing-incidence diffraction (GID). At T≤15 °C the π A isotherms show two plateau regions indicating two first-order phase transitions. In the first main transition from the lowdensity fluid-like phase to a condensed phase, dendritic growth of condensed phase domains with six main growth directions was observed by BAM. A second transition from a condensed phase with large tilt angle to a condensed phase with smaller tilt angle and a denser arrangement of mol…

White Light-Emitting Electrochemical Cells Based on the Langmuir–Blodgett Technique

2014

Light-emitting electrochemical cells (LECs) showing a white emission have been prepared with Langmuir-Blodgett (LB) films of the metallosurfactant bis[2-(2,4-difluorophenyl)pyridine][2-(1-hexadecyl-1H-1,2,3-triazol-4-yl)pyridine]iridium(III) chloride (1), which work with an air-stable Al electrode. They were prepared by depositing a LB film of 1 on top of a layer of poly(N,N'-diphenyl-N,N'-bis(4-hexylphenyl)-[1,1'-biphenyl]-4,4'-diamine (pTPD) spin-coated on indium tin oxide (ITO). The white color of the electroluminescence of the device contrasts with the blue color of the photoluminescence of 1 in solution and within the LB films. Furthermore, the crystal structure of 1 is reported togeth…

Angular shift of an electromagnetic beam reflected by a planar dielectric interface

1989

A mathematical procedure for obtaining theoretically an expression for the fields of a beam reflected by a planar interface separating two lossless, linear, isotropic, homogeneous media is presented. Comparison of this expression with that obtained when the beam undergoes reflection from a perfect conductor leads to the expression for the angular shift of the beam reflected by a planar dielectric interface. The cases of normal and parallel polarization of a microwave beam are considered. In the last case, a complete study for angles of incidence far and near the Brewster angle is made.

Brewster angle microscopy and X-ray GID studies of morphology and crystal structure in monolayers of N-tetradecyl-γ,δ-dihydroxypentanoic acid amide

1997

First-order phase transitions from the low-density fluidlike phase to the condensed phase of monolayers of N-tetradecyl-γ,δ-dihydroxypentanoic acid amides at the air−water interface have been studied by π−A isotherms, Brewster angle microscopy (BAM), and synchrotron X-ray grazing incidence diffraction (GID). The thermodynamic differences between enantiomeric and racemic monolayers are too small to be measured. However, chiral discrimination is observable in the macroscopic domain morphology by BAM. The domains of the condensed phase grow dendritically. The characteristic shapes of domains of the pure S and R enantiomers are mirror images of each other. The domains of the racemic mixture are…

Patterning of Magnetic Bimetallic Coordination Nanoparticles of Prussian Blue Derivatives by the Langmuir–Blodgett Technique

2012

We report a novel method to prepare patterns of nanoparticles over large areas of the substrate. This method is based on the adsorption of the negatively charged nanoparticles dispersed in an aqueous subphase onto a monolayer of the phospholipid dipalmitoyl-l-α-phosphatidylcholine (DPPC) at the air-water interface. It has been used to prepare patterns of nanoparticles of Prussian blue analogues (PBA) of different size (K(0.25)Ni[Fe(CN)(6)](0.75) (NiFe), K(0.25)Ni[Cr(CN)(6)](0.75) (NiCr), K(0.25)Ni[Co(CN)(6)](0.75) (NiCo), Cs(0.4)Co[Cr(CN)(6)](0.8) (CsCoCr), and Cs(0.4)Co[Fe(CN)(6)](0.9) (CsCoFe)). The behavior of DPPC monolayer at the air-water interface in the presence of the subphase of P…

Contributions Regarding the Reduction of Production Costs for Brewing by Recovering and Reusing the Carbon Dioxide

2014

Abstract Nowadays in every field the main aim is to produce corresponding quality products at competitive prices for buyers. In addition to the multiple possibilities to reduce the brewing production cost, one of the most significant ways is to reduce the production cost by recovering the carbon dioxide (CO2) resulting from the fermentation of beer, taking into account the fact that the CO2 thus resulting is completely natural. This scientific paper presents a certain strategy based on costs, strategy which relies on the experience of the authors, on the economic impact of CO2 recovery resulting from the fermentation of beer and which reflects itself in the production cost and implicitly in…

Ekskurs XI. Sprofanowana świątynia (Ez 8,1-18) i dolina suchych kości (Ez 37,1-14) w świetle retoryki hebrajskiej

2021

Kontekstem badań było to, że komentatorzy Księgi Ezechiela nie są zgodni w sprawie struktury badanych tekstów i proponują odmienne schematy. Celem badań stało się odkrycie struktury, którą starożytny autor natchniony zawarł w tekście. By osiągnąć założony cel, zastosowano metodę retoryki hebrajskiej, którą opracował Roland Meynet. W wyniku przeprowadzonych badań udało się odkryć, że sprofanowana świątynia ma strukturę paralelno-koncentryczną, składającą się z 9 elementów (A, B, C, D, E, D’, C’, B’, A’), natomiast dolina suchych kości też ma strukturę paralelno-koncentryczną, na którą składa się 5 elementów (A, B, C, B’, A’). Osiągnięte wyniki pozwoliły wyciągnąć wspólny wniosek dla dwóch ba…

Soundless Screams: Graffiti and Drawings in the Prisons of the Holy Office in Palermo

2017

The discovery of graffiti in the early years of the twentieth century by the folklorist Giuseppe Pitré left by prisoners of the tribunal of the Spanish Inquisition in Palermo has been followed by more extensive investigations in recent years. These images and words have added a concrete and particular dimension to Sicily’s position at the crossroads of the Mediterranean. As well as images of saints and naval battles are to be found inscriptions not only in Italian, Sicilian and Latin but also in English and Hebrew. This article cross references this visual and textual evidence with the relevant archives of the tribunal in order to provide a powerful microhistory of suffering and resilience …
