A partial decrease of the convective energy by the magnetic field of a sunspot causes the temperature of the magnetized plasma to decrease and this leads to a magneto-hydrostatic equilibrium. Thus, we expect a strong relation between magnetic field strength of a sunspot and its temperature/brightness. Here, we investigate this relation in the umbra of the large sunspot in NOAA10930 using spectr...

Background: Sun protection materials have been one of the major concerns in pharmaceutical industry since almost one century ago. Various materials have been found to have such an effect but there are still many unknown substances that have not been discovered.Objective: To introduce a novel mineral-based sun lotion with considerable UV absorption properties compared to commercially available s...

distribution of magnetic fields in the quiet-sun internetwork areas has been affected by weak polarization (in particular stokes q and u) signals. to improve the signal-to-noise ratio (snr) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. in this study, we aim to investigate a proper temporal-integration time with which...

Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study, the effects of concentrate of smoked and sun dried raisin were investigated at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread. Results showed that addition of smoked and sun dried raisin improved quality a...
