Aim To report on outcomes of gonioscopy-assisted transluminal trabeculotomy (GATT) in eyes with pseudoexfoliative glaucoma (PXG). Methods Prospective, interventional, non-comparative case series. A total 103 from 84 patients PXG were enrolled to undergo a 360-degree ab interno gonioscopic assistance using either 5.0 polypropylene suture or an illuminated microcatheter up 24 months follow-up. Main outcome measures intraocular pressure (IOP), number antiglaucoma medications, success rate (IOP...
Broad-band (ultraviolet to near-infrared) observations of the intense gamma ray burst GRB 990123 started ∼8.5 hours after event and continued until 18 February 1999. When combined with other data, in particular from Robotic Telescope Transient Source Experiment (ROTSE) Hubble Space (HST), evidence emerges for a smoothly declining light curve, suggesting some color dependence that could be related cooling break passing ultraviolet-optical band at about 1 day high-energy event. The steeper...
We present optical photometry and spectroscopy of the X-ray transient XTE J1859+226, obtained during outburst its subsequent decay to quiescence. Both properties are very similar those well-studied black hole soft transients. have detected three mini-outbursts, when J1859+226 was approaching quiescence, as has been previously in transients GRO J0422+32 GRS 1009–45. By 2000 August 24 system had reached quiescence with R= 22.48 ± 0.07. The estimated distance source is ∼11 kpc. Photometry taken...
GRB 021004 is one of the best sampled gamma-ray bursts (GRB) to date, although nature its light curve still being debated. Here we present a large amount (107) new optical, near-infrared (NIR) and millimetre observations, ranging from 2 hours more than year after burst. Fitting multiband data model based on multiple energy injections suggests that at least 7 refreshed shocks took place during evolution afterglow, implying total release (collimated within an angle 1.8 deg) ~ 8x10^51 erg....
We imaged the position of naked-eye burst, GRB080319B, before, during, and after its gamma-ray activity with sub-second temporal resolution using TORTORA wide-field camera. The burst optical prompt emission, which reached 5.3 mag, has been detected, periodic variability discovered in form four equidistant flashes a duration several seconds. also detected strong correlation (r ≈ 0.82) between light curves 2 s delay emission respect to emission. revealed structure curve comparison can be...
The GRB010222 optical and near-infrared (NIR) afterglow was monitored at the TNG other Italian telescopes starting ∼1 day after high-energy prompt event.The BV R light curves, which are best sampled, continuously steepening can be described by two power laws, f (t) ∝ t -α , of indices α1 ∼ 0.7 α2 1.3 before a break occurring about 0.5 days GRB start time, respectively.This model accounts well also for flux in U I J bands, less monitored.The temporal appears to achromatic.The K-band points...
We report on ASCA and BeppoSAX X–ray broad band observations of the galactic low-luminosity source 4U 1700+24 performed 1995 1998, respectively, (quasi-)simultaneous ground its optical counterpart, V934 Her, from Loiano 1.5-meter telescope. In order to better understand nature we also analyze public archival ROSAT RXTE data as well ASM light curve 1700+24; re–analyze a 1985 EXOSAT pointing. The spectra are typical M2 III star; this allows us determine revised distance object ~400 pc. While...
Aims: With this paper we want to investigate the highly variable afterglow light curve and environment of gamma-ray burst (GRB) 060526 at $z=3.221$. Methods: We present one largest photometric datasets ever obtained for a GRB afterglow, consisting multi-color data from ultraviolet near infrared. The set contains 412 points in total which add additional literature. Furthermore, low-resolution high signal-to-noise spectra afterglow. is modeled with both an analytical model using broken power...
We report near-infrared and optical follow-up observations of the afterglow GRB 000418 starting 2.5 days after occurrence burst extending over nearly 7 weeks. represents second case for which was initially identified by in near-infrared. During first 10 its R-band well characterized a single power-law decay with slope 0.86. However, at later times temporal evolution flattens respect to simple decay. Attributing this an underlying host galaxy, we find magnitude be R = 23.9 intrinsic 1.22. The...
Physical-mechanical properties of egg constituents and their modifications during storage poststorage greatly influence the efficiency food processing, such as separation white yolk by mechanical shelling. Thick albumen height, Haugh unit, index vitelline membrane-yolk system strength eggs from Hy-Line White Lohmann Brown hens were analyzed 7 mo at 0 degrees C performing 3 treatments: i) immediately after refrigeration, T1; ii) a further 6 h 18 T2; iii) week T3. For all qualitative...
