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...

A non-ionic surfactant (Genapol OX-80) was proposed as a means of reducing destructive crayfish activity in rice. In order to study the toxicity of this product on algae, a test in accordance to the ISO 8692 protocol (1989) was performed. The growth inhibiting effect of the pure formulation of Genapol OX-80 was studied on Selenastrum capricornutum in the concentration range of 0.01-1.0 mg/l. Th...

the main purpose of this study was to determine which correlate, perceived motor competence or motor skill competence, best predicts girls' physical activity behavior.a sample of 352 girls (mean age=8.7, sd=0.3 yr) participated in this study. to assess motor skill competence and perceived motor competence, each child completed the test of gross motor development-2 and physical ability sub-scale...

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.

today, effective interpersonal relationships are key factors for success of the organizations. so, we need to examine and understand the social competence that is required for effective interpersonal relationship. humor is a common communicational strategy that it can have an important role in social competence and interpersonal relationship. this research has attempted to examine the impact of...
