The Central Temperature of the Sun can be Measured via the 7 Be Solar

چکیده

A precise test of the theory of stellar evolution can be performed by measuring the diierence in average energy between the neutrino line produced by 7 Be electron capture in the solar interior and the corresponding neutrino line produced in a terrestrial laboratory. The high temperatures in the center of the sun broaden the line asymmetrically, FWHM = 1.6 keV, and cause an average energy shift of 1.3 keV. The width of the 7 Be neutrino line should be taken into account in calculations of vacuum neutrino oscillations.

سینتیک افت رطوبت و مقایسه کیفیت ورقه‌های گوجه‌فرنگی در مرحله خشک‌شدن با سه روش: خشک‌کردن خورشیدی، آفتابی سنتی و هوای خشک

Sun drying is a well-known food preservation technique that reduces the moisture contents of agricultural products. Shrinkage, rehydration ability and color of food materials during air drying adversely affect the quality of the dried products. Since all fresh tomatoes can not be consumed at the time of harvest, preservation provides a larger market, allowing consumers to buy the preserved toma...

Designing a Solar Tracker in the Form of Smart Light Curtain

One of the methods for increasing the gain in the photovoltaic systems is using the solar tracker system which during the whole of day, align the solar panels in the proper position with respect to the sun position. In this study, a solar tracker in the form of smart light curtain was designed and prepared. This simple and smart tracker detects the direction of the sun radiation by using three ...

An experimental investigation on the performance of a symmetric conical solar collector using SiO2/water nanofluid

One of the effective methods to improve the thermal efficiency of solar collectors is using nanofluids as the coolant. The present study experimentally investigated the effect of SiO2/water nanofluid with 1% mass fraction on the performance of a symmetric collector, i.e. conical solar collector. The conical solar collector with 1 m2 area and normal to the earth was tested in Ahvaz, a city in th...
