We present results of intraday variability observations at 5 GHz of the EGRET blazars 0202+14, 0235+16, 2230+11, and 2251+15. The BL-Lac object 0235+16 presented flux density variations of ∼ 7 % over timescales of ∼ 1.3 days. The source 0202+14 was also variable, although with smaller amplitudes. The behaviour of 0235+16 at short timescales is almost identical to that presented in previous intr...

ABSTRACT We report here results of the analysis correlated flux variations between optical and GeV γ-ray bands in three bright BL Lac objects, namely AO 0235+164, OJ 287, PKS 2155−304. This was based on about 10 yr data from Fermi Gamma-ray Space Telescope covering period 2008 August 8 2018 along with same period. For all sources, during flares analysed this work, are found to be closely correl...

AO 0235+164 is a very compact, flat spectrum radio source identified as a BL Lac object at a redshift of z = 0.94. It is one of the most violently variable extragalactic objects at both optical and radio wavelengths. The radio structure of the source revealed by various ground-based VLBI observations is dominated by a nearly unresolved compact component at almost all available frequencies. Dual...

El objetivo de este estudio fue analizar los efectos del entrenamiento funcional en indicadores fuerza muscular, capacidad y calidad vida (CV) personas con lesion medular espinal (LME). La muestra se compuso 5 individuos adultos LME ambos sexos, que sometieron a 12 semanas dos veces la semana. Antes despues dicho entrenamiento, analizaron potencia anaerobica (PAN), agilidad desplazamiento, musc...

We have performed a structure function analysis of the Rossi X-ray Timing Explorer All Sky Monitor data to search for variability in 24 blazars using data trains that each exceed 12 years. Although 20 of them show nominal periods though this technique, the great majority of these ‘periods’ are clearly related to yearly variations arising from the instrument. Nonetheless, an apparently real peri...

Periodic outbursts are observed in many AGNs and usually explained with a supermassive black hole binary (SMBHB) scenario. However, multiple periods are observed in some AGNs and cannot be explained with it. Here we analyze the periodicity of the radio light curves of AO 0235+164 at multi-frequencies and report the discovery of six QPOs in integer ratio 1:2:3:4:5:6 of QPO frequencies, of which ...

The in vitro activity of PA-824 and BTZ043 against 30 Nocardia brasiliensis isolates was tested. The MIC(50) and MIC(90) values for PA-824 were both >64 μg/ml. The same values for BTZ043 were 0.125 and 0.250 μg/ml. Given the MIC values for benzothiazinone (BTZ) compounds, we consider them good candidates to be tested in vivo against N. brasiliensis.

We selected a sample of a dozen blazars which are the prime candidates for simultaneous multi-wavelength observing campaigns in their outburst phase. We searched for optical outbursts, intra-day variability and short term variability in these blazars. We carried out optical photometric monitoring of nine of these blazars in 13 observing nights during our observing run October 27, 2006 − March 2...
