Optical emission-line profiles were evaluated in order to explore the structure of galactic nuclei containing H2O megamaser sources. Long-slit spectra of IC 2560, NGC1386, NGC1052 and Mrk 1210 were obtained at ∼ 100 km/s spectral and ∼ 2′′ × 2′′ spatial resolution. The following individual properties of the objects were found: The active nucleus of IC2560 (innermost ±2′′) emits lines typical fo...

Using the evaporating method, the solubility of potassium Nitrate was determined in various mixtures containing Water and Ethanol at 25°C. The results show that the solubility of KNo3 decreases with increasing the mass percent of Ethanol in the mixtures. This trend is along with decreasing the dielectric constant of Water+Ethanol mixtures. Moreover, it can be concluded that the totqal solubilit...

GENETICS OF FOOD ALLERGIES 2 This paper purports that genetic factors assume the greatest influence over the development of food allergies in humans. A number of researchers argue that environmental factors play a more dynamic role, especially in the early development of the allergic condition. Through an examination of the process of an allergic reaction and an analysis of statistics and recen...
