Opis:
Granular materials have vast applications both in industry and in daily life. They display quite interesting and exceptional properties different from the other known forms of matter. To investigate the complex properties of particulate materials, experimental, analytical, and numerical techniques have been employed. In this paper the results of experimental and numerical tests of various grain sizes and coefficient of friction between granules and cylindrical walls on the mass measured at bottom of container, known as apparent mass, are reported. It is revealed that apparent mass augments with the grain size. Moreover, it is also found that the variation in apparent mass measurement is strongly dependent on bead diameter rather than the silo size. The results suggest that the conversion of vertical stresses into horizontal in silo is mainly due to the friction between the grain and system boundary than the arching phenomenon.

Opis:
The objective of this study is to control the air quality parameters for a selected range of different particulate matters. A comprehensive experimental approach is established to regulate the quality of air about a selected range of different air pollutants being investigated in the indoor atmosphere of the church building. Relative humidity, temperature, carbon dioxide, particulate matter and radon were considered as the factors of air quality extents. For establishing the association among the selected parameters, the data were mathematically analyzed. The correlation coefficient confirmed a strong relationship between the indoor CO2 level and the number of public. A negative relationship between the indoor CO2 extent and indoor temperature confirmed that due to the increase in temperature the concentration of CO2 decreased as well. A solid adverse connection among indoor relative humidity and indoor air temperature showed that due to the increase in air temperature, the level of the relative humidity decreased. Some recommendations were proposed for the treatment of air quality in church buildings for human well-being.
