MOJAVE. XIII. New 15GHz observations on 1994-2013
2017
We present 1625 new 15GHz (2cm) VLBA images of 295 jets associated with active galactic nuclei (AGNs) from the MOJAVE and 2cm VLBA surveys, spanning observations between 1994 August 31 and 2013 August 20. For 274 AGNs with at least 5 VLBA epochs, we have analyzed the kinematics of 961 individual bright features in their parsec-scale jets. A total of 122 of these jets have not been previously analyzed by the MOJAVE program. In the case of 451 jet features that had at least 10 epochs, we also examined their kinematics for possible accelerations. At least half of the well-sampled features have non-radial and/or accelerating trajectories, indicating that non-ballistic motion is common in AGN je…
Radio-optical scrutiny of compact AGN
2010
We study the correlations between the VLBA (Very Long Baseline Array) radio emission at 15GHz, extended emission at 151MHz, and optical nuclear emission at 5100{AA} for a complete sample of 135 compact jets. We use the partial Kendall's tau correlation analysis to check the link between radio properties of parsec-scale jets and optical nuclear luminosities of host active galactic nuclei (AGN).

NATIONAL COMPETITIVENESS - SCENARIOS FOR ROMANIA
2012
Competitiveness remains a continuous concern of nations in any stage of development, from factor based economy to innovation based economy. The present paper aims to emphasize the current level of national competitiveness of Romania, on one hand, and to identify possible ways to improve the current level by building scenarios in order to eliminate the uncertainty, on the other hand. The paper proposes four scenarios for increase GCI (growth competitiveness index) and four scenarios from pessimistic point of view (in these scenarios GCI will be decrease). In the near future, Romania must improve their pillars of national competitiveness and must increase their GDP per capita for transition p…
Laboratory formation of a scaled protostellar jet by coaligned poloidal magnetic field
2014
International audience; Although bipolar jets are seen emerging from a wide variety of astrophysical systems, the issue of their formation and morphology beyond their launching is still under study. Our scaled laboratory experiments, representative of young stellar object outflows, reveal that stable and narrow collimation of the entire flow can result from the presence of a poloidal magnetic field whose strength is consistent with observations. The laboratory plasma becomes focused with an interior cavity. This gives rise to a standing conical shock from which the jet emerges. Following simulations of the process at the full astrophysical scale, we conclude that it can also explain recentl…

ON THE FON ASTROPLATE PROJECT ACCOMPLISHMENT
2019
The plan of the photographic survey of thenorthern sky (FON) was proposed in 1976 in Golosiiv ob-servatory (now MAO NAS of Ukraine) by I. Kolchinskyand A. Onegina. The final project of the Compiled FONACcatalog (FON Astrographic Catalog) is based on the digitaldata of photographic plates exposed at four observatories.They are MAO NAS of Ukraine (Kyiv, Ukraine), Kitabastronomical observatory (Tashkent, Uzbekistan), Hissarastronomical observatory (Dushanbe, Tajikistan), and Bal-done observatory (Latvia)). The total amount of plates is5700. The result is expected to be the catalog of positionsand B-magnitudes of stars covered the declination areafrom -20 to 90 degrees. The estimated mean epoch…
Synthetic Approaches to the Lamellarins—A Comprehensive Review
2014
The present review discusses the known synthetic routes to the lamellarin alkaloids published until 2014. It begins with syntheses of the structurally simpler type-II lamellarins and then focuses on the larger class of the 5,6-saturated and -unsaturated type-I lamellarins. The syntheses are grouped by the strategy employed for the assembly of the central pyrrole ring.
Determining the infrared radiative effects of Saharan dust: a radiative transfer modelling study based on vertically resolved measurements at Lampedu…
2018
Detailed measurements of radiation, atmospheric and aerosol properties were carried out in summer 2013 during the Aerosol Direct Radiative Impact on the regional climate in the MEDiterranean region (ADRIMED) campaign in the framework of the Chemistry-Aerosol Mediterranean Experiment (ChArMEx) experiment. This study focusses on the characterization of infrared (IR) optical properties and direct radiative effects of mineral dust, based on three vertical profiles of atmospheric and aerosol properties and IR broadband and narrowband radiation from airborne measurements, made in conjunction with radiosonde and ground-based observations at Lampedusa, in the central Mediterranean. Satellite IR spe…
The Hyperreal Gambler : On the Visual Construction of Men in Online Poker Ads
2017
Online poker, like gambling in general, is predominantly a male activity. Thus, poker ads most often depict men as their protagonists. According to Jean Baudrillard, advertising can be seen as a ‘plebiscite whereby mass consumer society wages a perpetual campaign of self- endorsement.’ Ads often use stereotypical imagery for establishing a shared experience of identification with the consumer, and since their role is to sell rather than to portray the realities of life, they often have an exaggerated and monolithic – or, hyperreal – way of representing gender. This article offers an analysis of the ways in which men are portrayed in the ads of Poker Magazine Finland in the volume of 2009 (a…
Variacions sobre el tema "Corella i els contemporanis valencians"
1998
The author provides data concerning the interrealtion between Corella's work and that of some of hiscontemporaries -precisely Ausiàs March, Joan Moreno and Bernat Fenollar-. He analyses in detail the jovial poem dedicated to Bernat del Bosch - a character here identified as historical, and executed for his homosexuality.
