Optical properties of the low-molecular amorphous azochromophores and their application in holography

2015

The films based on the low-molecular amorphous azochromophore 2-(3-(4-((4- (Ethyl(2-(trityloxy)ethyl)amino)phenyl)diazenyl)styryl)-5,5-dimethylcyclohex-2-enylidene) malononitrile (IWK-2M) were prepared. The optical properties of the material, such as transmittance and reflection spectra of the film, sensitivity to polarization holographic recording by two wavelengths (405 and 532 nm) were studied. The direct relief formation during the polarization holographic recording was explored, relief depth dependence on exposure and record beam intensity was investigated. The holographic matrix on this material base was produced without chemical etching process; the replication of holographic image w…

Anomalous behaviour of periodic domain structure in Gd-doped LiNbO3single crystals

2007

Atomic force microscopy studies of etching patterns, stability of regular domain structure, and anomalies of electrical characteristics in the 300 - 385 K range of a series of Gddoped lithium niobate single crystals grown under equal conditions are reported.

An Anthropological Insight on the Commonalities between Tourism and Archaeology

2019

Over the years, archaeology maturated towards something else than a scientific discipline. Archaeological sites are culturally showed as emerging and recycled tourist attractions (Robb 1998; Bateman 2006; Rowan & Baram 2004; Karlsson & Gustafsson, 2006). At a closer look, tourism is understood as a leisure activity which is enrooted in the needs of relaxing and evasion while archaeology -as a knowledge platform which is based on scientific method- explores the history of ancient cultures. This raises a more than interesting question respecting the commonalities and differences between archaeology and tourism. To some extent, archaeologists find ancient relics and objects whi…

THE OLIGARCH AND THE PAINTBRUSHES: A BIOGRAPHICAL SKETCH OF ANDREU GARCIA, PRIEST = EL OLIGARCA Y LOS PINCELES: BREVE SEMBLANZA DEL PRESBÍTERO ANDREU…

2014

The documents regarding the Valencian priest Andreu Garcia († November 1452) show a quite interesting character. Garcia’s family belonged to local oligarchy. Moreover, he had a substantial income related with the Cathedral. He had contact, too, with Carthusians, Observant Friars and probably with Beghards (the books of his library suggest this last idea). Garcia took part, as an intermediary or as a sponsor, in many artistic orders that involved the best workers and the best customers of the city. Besides, he had a strong relationship with painters like Simó Llobregat, Jaume Mateu, Gonçal Sarrià and Joan Reixac. The priest could also have practiced painting, judging by the belongings that w…

Epäkerrotun mahdollisuuksia Elina Hirvosen romaanissa Että hän muistaisi saman

2012

The possibilities of the disnarrated in Elina Hirvonen’s novel When I Forgot Anna, the character-narrator of When I Forgot (2005), a debut novel by Elina Hirvonen, spends the present-day of the novel sitting in the cafes and remembering the past. She works through some traumatic events and embarrassing situations, and speculates what could have happened. Her unrealized desires, fantasies etc. constitute what Gerald Prince calls the disnarrated. As delineated by Prince, the disnarrated refers to those events that remain unrealized though they are given as possible or actual elements of the narrative. It can fulfill various functions of which the present article examines its possibilities as …

La representación eufemística de la relación gay en el periodismo serio

2011

La visibilidad de las relaciones homosexuales ha logrado un espacio considerable y una cobertura relativamente digna en los medios de comunicación social, tanto en contenidos informativos como de entretenimiento. Sin embargo, esta representación continúa sufriendo un tratamiento estigmatizador en determinados discursos periodísticos, que emplean el eufemismo como recurso para aludir a las parejas formadas por dos hombres o dos mujeres, sobre todo en noticias que abordan asuntos considerados especialmente sensibles o serios como las grandes tragedias o el fallecimiento de personas ilustres. Este trabajo, que pretende conocer qué consecuencias tiene esta práctica en las características propia…

Bactericidal Effect of the Er:YAG Laser on Dental Implant Surfaces: An In Vitro Study

2002

The aim of the in vitro study was to examine the bactericidal effect of an Er:YAG laser on common dental implant surfaces.Seventy-two titanium platelets with 3 different surfaces--sandblasted and acid-etched (SA), titanium plasma-sprayed (TPS), and hydroxyapatite-coated (HA)--were incubated with a suspension of Streptococcus sanguinis (ATCC 10556). Irradiation at pulse energies of 60 and 120 mJ and a frequency of 10 pps was performed on a computer-controlled XY translation stage. After laser treatment the specimens were sonicated and the bacterial growth examined by counting colony forming units on blood agar plates. Temperature elevations during irradiation were investigated using K-type t…
