We present quasi-simultaneous ASCA and RXTE observations of the most luminous known AGN in the local (z < 0.3) universe, the recently discovered quasar PDS 456. Multiwavelength observations have been conducted which show that PDS 456 has a bolometric luminosity of ∼ 10 erg s peaking in the UV part of the spectrum. In the X-ray band the 2-10 keV (rest-frame) luminosity is 10 erg s. The broad-ban...

Aims. We test the technique of spectro-astrometry as a potential method to investigate the close environment of massive young stars. Methods. Archival VLT near infrared K band spectra (R=8900) of three massive young stellar objects and one Wolf-Rayet star are examined for spectro-astrometric signatures. The young stellar objects display emission lines such as Brγ, CO 2-0 and CO 3-1 that are cha...

Background: The etiology of preeclampsia remains less well known. It is noted that low vitamin D levels are associated with a high risk (PE). Calcium (Ca2+) during pregnancy appear to be involved in pregnancy-induced hypertension. Recent studies indicate serum calcium may have role preeclampsia. Vitamin promotes absorption proper concentration the blood which helps lower pressure. complications...

The quenching of sonoluminescence from aqueous solutions by acrylic and methacrylic acids is dependent on whether the acid is ionised in solution, as controlled by the pH, but also by the frequency of ultrasound used.

FIGURE 1 Scheme of a batch separation process. The resin is made by crosslinking divinyl benzene (DVB) with a polystyrene matrix, which contains sulphoriic groups for cation attachment. The resinsare manufactured as beads which, when packed in a column, provide interstitial spaces for the passage of large molecules. Generally, non-ionised smaller moleculessuch as sucrose, glucose and fructosear...

Arterial interstitial cells of Cajal (ICC)-like cells (AIL cells) with a multipolar, irregular, elongated shape and with numerous thin (often less than 1 microm), sometimes branching, processes with lengths up to approximately 60 microm were isolated enzymatically from 1st to 7th order branches of guinea-pig mesenteric artery. Some of the processes of AIL cells were growing (average speed appro...

OBJECTIVE Vitamin D deficiency is prevalent in critically ill patients and may contribute to suboptimal clinical outcomes, but little is known about alterations of the calcium-parathyroid hormone (PTH)-vitamin D axis and prognosis in these individuals. METHODS A prospective observational study was conducted on 216 patients admitted to a university-affiliated, tertiary-care medical intensive c...
