7(c) shows that the pollutant concentrations are seasonal, being lowest in the summer season and highest from January to May. SO2 and NO2 concentrations show similar seasonal trends that can be attributed to the decrease in traffic density and industrial emissions during the summer holidays. The...
If an object of massmoccupies a volumeV, then its densityρis given as: ρ=mV. We can apply this formula to find the missing parameter if the remaining two are known. Answer and Explanation: Given m=50.0g ρ=1.19×10−3g/cm3 ...
Air at a Mach number 3.0, a pressure 50 kPa, and a temperature 200K undergoes compression shock at a corner of \theta=20 degrees , as shown in the figure below. At the point where shock intersects the Air enters an adiabatic compressor at steady...
According to World Health Organization, 9 out of 10 people breathe polluted air and the ambient air pollution accounts for nearly 4.2 million early deaths
For proliferation studies cells were seeded at a density of 2 ×105 cells into 75cm2 flasks and cultured for 4 days at which point the cells were still sub-confluent. Cells were counted using a Cellometer Auto T4 (Nexcelom Bioscience). Doubling time (DT) was calculated using the following ...
