AN URARTIAN GRAVE IN AGHAVNADZOR, VAYOTS DZOR, ARMENIA

In 2013 an Urartian tomb has been identified by chance during the construction of a house in the village of Aghavnadzor in Vayots Dzor Region, Armenia. Despite the tomb was heavily damaged, archaeologists were able to dig it and document it before its destruction. The multiple burial showed the contemporary coexistence of inhumation and incineration, according to a funerary practice well known in Urartian times. A good amount of grave goods have been recovered and restored. Most of it shows typical Urartian features with some interesting exceptions that refer to contemporary Assyrian models. The grave has been dated back to the 8th century thanks to 14C. In the present poster, the materials of the grave are presented and discussed. This discovery is particularly important because gives new information on the Urartian occupation of this part of the Armenian Highlands and, in particular, of the Vayots Dzor Region. The tomb will be discussed in the wider frame of the important Urartian evidence already known in the region, like the so-called ‘tomb of Yeghegnadzor’.

From polipharmacy to monotheraphy a case about schizoaffective disorder

The aim of the present poster is to describe an initial complex case of schizoaffective disorder with other clinical adverse conditions (metabolic disorders) in a young adult male, which gradually went into a positive treatment way from polipharmacy to monoteraphy. His psychiatric history started when he was 25-year-old, he was diagnosed of heroine dependence, hypercholesterolemia and hypertrigliceridemia. In 2000 he had a suicide attempt in a context of depressive mood and delusions. He needed a psychiatric hospitalization for the first time in his life and he received anti-psychotics for the first time too. Drug abuse was detected in that hospitalization (cannabis and alcohol). In 2001 was diagnosed of paranoid schizophrenia. In 2007 the diagnosis was modified to schizoaffective disorder and also was detected high blood pressure, Diabetes Mellitus II and overweight. From 2007 to the present he passed from a scheme treatment composed by four or more psychotropic drugs to monotherapy (only one psychotropic drug, an anti-psychotic), he stayed clinically stable and all his metabolic parameters remained equal or improved.Disclosure of interestJanssen-Cilag research study.

A new approach to hull consistency

Hull consistency is a known technique to improve the efficiency of iterative interval methods for solving nonlinear systems describing steady-states in various circuits. Presently, hull consistency is checked in a scalar manner, i.e. successively for each equation of the nonlinear system with respect to a single variable. In the present poster, a new more general approach to implementing hull consistency is suggested which consists in treating simultaneously several equations with respect to the same number of variables.

First Results of the Analysis of the Wolf-Rayet Star WR6

We present the first results of our analysis of the famous variable star, WR6 (HD50896). Using IUE ultraviolet data and an ESPaDOnS spectropolarimetric survey of this star, we plan to determine possible variation of the stellar and wind parameters during the different phases using the radiative transfer code CMFGEN. After the detection of parameter's modifications as a function of the phase, we will analyse deeper the origin of these variability (for example, CIRs?). In the present poster we show the first results of our analysis of the variability and the first step of the stellar parameter determination of the average spectrum of this star.

Wind inhomogeneities in [Wc] central stars of planetary nebulae

In the present poster paper, we summarize the observational spectroscopic evidence for wind clumping originating in some [WC8-10] and [WO4] central stars of planetary nebulae. Specifically, we concentrate on the C iii λ5696 and C iv λλ5801/12 emission-line variability observed for well-known planetary nebula nuclei.

Importance of the Alkaline Degradation of Cellulose in Performance Assessment of a Cementitious Radioactive Waste Repository

It is the aim of the present poster to show two approaches for assessing the influence of the alkaline degradation of cellulose on the sorption of tri- and tetravalent radionuclides. The two approaches differ in their degree of conservativity, one is a conservative, the other a realistic model case. The result of both examinations is expressed in terms of sorption reduction factors, valid for a situation where cellulose degradation products are influencing the sorption of radionuclides on cement.

Interaction of Planetary Nebulae by Prenebulae Debris

In the present poster we suggest that some of the structures observed in the envelopes of planetary nebulae are caused by the interaction of central star wind and radiation with preplanetary nebula debris: planets, moons, minor objects, ring and ring arcs.

Amplitude of RR Lyrae Star Light Curves: Comparison between Observations and One—Zone Model Predictions

Stellingwerf's one–zone model is a simple and useful tool for reproducing the main observed pulsational characteristics of RR Lyrae and high amplitude δScuti stars, in particular their light and color curves (Stellingwerf et al., 1987, Ap.J.313, L75; Antonello, 1990, Astr. Ap.230, 127). In the present poster we show in better detail a comparison of the observed amplitudes of the light curve at various wavelengths with those predicted by the one–zone model; a preliminary result on this subject was reported in the short note by Grieco and Antonello (1990, in Confrontation between Stellar Pulsation and Evolution p. 101). As in the previous applications, here we use the published grids of atmospheric models (Kurucz, 1979, Ap.J.Suppl. 40, 1) and we do not consider possible shock effects.

Gravitational Lensing: Cosmological Implications

In the present poster, we first address theoretically the problem of gravitational amplification by extended density fluctuations and then compare statistically our new predictions to actual samples of galaxies and QSOs.
