We consider the influence of (milli/micro)lensing on the spectra of lensed QSOs. We propose a method for the observational detection of microlensing in the spectra of lensed QSOs and apply it to the spectra of the three lensed QSOs (PG 1115+080, QSO 1413+117 and QSO 0957+561) observed with Hubble Space Telescope (HST). We find that the flux ratio between images A1 and A2 of PG 1115+080 is wavel...

We describe a rare case of multiple coronary artery-left ventricular fistulas associated with apical hypertrophic cardiomyopathy in a 62 year asymptomatic old male admitted to our department for a perioperative evaluation of non cardiac surgery, already diagnosed for multiple coronary artery-left fistulae. He underwent transthoracic echocardiography and then to accelerated dipiridamole stress-e...

We prove that a curious generating series identity implies Faber's intersection number conjecture (by showing it combinatorial already given in (Garcia-Failde, Kramer, Lewański, and Shadrin, SIGMA 15 (2019), 080)) give new proof of by directly proving this identity.

Abstract Iridoids are a class of secondary metabolites found in wide variety plants. typically plants as glycosides, most often to glucose. The genus Stachys L. is one the largest genera Lamiaceae family, containing iridoids. Aim aim this study was isolation and identification iridoids from aerial parts byzantina K. Koch germanica Methods For iridoids, different chromatographic methods (NP-TLC,...

Sorghum (Sorghum bicolor L. Moench) is a native grass species of the arid and semi-arid regions of Africa (Kimber 2000). Sorghum is a genetically diverse crop and contains some genotypes that have a pigmented testa and therefore contain tannins (Rooney et al 1980; Rooney and Miller 1982). Such lines have the dominant B1_B2_ genes and are the only sorghum types with tannins (Blakeley et al 1979)...
