Electrooptic beam deflection with latex
1988
The use of latex in electrooptic devices is proposed. The static non linearity coefficient is shown to be approximatively 200 times the optical one. The theory of a beam deflector is developed and an explicit expression is given for the deflection angle versus the physical parameters of the sample Utilisation de suspensions aqueuses de latex dans un dispositif electro-optique. On montre que le coefficient statique de non-linearite devrait etre 200 fois plus eleve que le coefficient optique. Application a un deflecteur optique
ON THE “SOLAR SYSTEM SMALL BODIES” ASTROPLATE PROJECT OF THE UKRAINIAN VIRTUAL OBSERVATORY
2019
The UkrVO Joint Digital Archive of astro- plates and the newest digitized data processing services al- lowed us to form a new approach for the creation of catalogs of astrometric and photometric characteristics of the Solar System bodies. Given this, the main goal of this approach was not only to complete the processing with the best possi- ble accuracy of high-quality and unprocessed earlier photo- graphic observations of the Solar System bodies but also to find new original data from these observations. As a result, more than 6,500 new astrometric positions and stellar magnitudes of asteroids, and 3,036 positions of outer planets (Pluto, Uranus, Neptune, Saturn, Jupiter) and their satelli…
Historic constructions of the early multinational: on power, politics and culture in Pan Am narratives
2018
This paper examines how Pan American World Airways (Pan Am) - an early incarnation of a multinational enterprise (MNE) - developed its image as an international company. In particular, we examine how the company developed and managed potentially conflicting narratives, including the modernising US company and the airline of 'the Americas' (specifically South America); the carrier of US national interests and the politically neutral actor serving to unify cultures; the purveyor of exotic experiences and the pioneer of modernism. Through a focus on organisational narratives, we reveal the powerful influence of such story telling (through design and serendipity) on images of the peoples and co…

Global responsibility: An exploratory corpus assisted discourse analysis of the Rohingya crisis in online media
2021
This study conducts an exploratory corpus-assisted discourse analysis of the representation of the Rohingya minority group across online news media in the United Kingdom. The purpose of the study is to identify and interpret the discursive patterns employed in popular online news media when depicting the Rohingya minority and associated crises affecting the group in Myanmar and worldwide. Through the use of a combination of frequency, collocation, and concordance analysis, a synchronic study was undertaken using data collected from fifteen major online news media producers in the United Kingdom. The data was collected over a period from January 2017 – August 2020 through freely accessible d…

Dalla memoria mitica alla memoria storica: gli storici e gli archivisti al servizio di una nuova costruzione della memoria delle comunità greco-alban…
2021
Il presente contributo propone la creazione di un archivio digitale inventato a favore di un nuovo apparato narrativo in relazione alle comunità italo-albanesi di Sicilia a dispetto di quello costruito su di esse nei secoli. Ignorando le testimonianze scritte del passato a favore di suggestioni interpretative, si è in quel modo contribuito alla costruzione di una sorta di ' epopea' arbëreshe. Nel tentativo di favorire altre e diverse narrazioni, si vuole riflettere sull'archivio come nuovo e privilegiato strumento di costruzione della memoria collettiva e di narrazione di luoghi e territori, condotta tramite la realizzazione di un progetto incentrato sul patrimonio documentario delle comuni…
HIGHLY EXCITED VIBRATIONAL STATES OF CYCLIC MOLECULES INVESTIGATED BY I.C.L.A SPECTROSCOPY WITH PHOTOACOUSTIC DETECTION
1991
The spectra of the fourth and fifth CH stretching overtones of cyclohexene and cyclopentene molecules and of some of their selectively deuterated derivatives have been measured by dye laser intracavity spectroscopy with photoacoustic detection. The intramolecular relaxation of the vibrational energy occurs principally through Fermi resonances with CH2 bending combinations in cyclohexene and through a coupling between the stretching and the ring puckering motions in cyclopentene.
Search for scalar leptoquarks from Z$^0$ decays
1992
We have searched for pair produced scalar leptoquarks each decaying to a quark and a charged lepton in a sample of 116 000 hadronic Z0 events produced at LEP. No candidate was detected and cross section and branching ratio limits are set for the above process at 95% CL. Mass limits are found to be about 42 GeV/c2 depending only slightly on the models used and a coupling times branching ratio exclusion line is drawn for a scalar leptoquark with a free coupling. We have also probed the mass region above 45 GeV/c2 for a singly produced scalar leptoquark and set limits on the cross section and the coupling lambda(2)/4-pi up to 60 GeV.
BALDONE OBSERVATORY IN THE CIRCLES OF TIME
2019
1957 – The first laboratory building, known as the White House, was built near Baldone on the Riekstu hill, in the territory of the next Observatory. 01.01.1958 – The Astronomy Sector was separated from the Institute of Physics and commenced independent activi- ty as the Laboratory of Astrophysics at the Latvian Acade- my of Sciences (LAS). In 1967, with the decision of the Presidium of the Latvian SSR LAS the Laboratory of As- trophysics was transformed into the Radioastrophysic Ob- servatory at LAS. Under the leadership of the first director, Janis Ikaunieks, an instrumental observation base develops – a 1.2m Schmidt telescope was installed in 1966 for opti- cal observations. The project …
