“…where  is The ratio of an electron's charge to its B is the first derivative of the axial magnetic flux density with respect to z. Spherical aberration is one of the very important aberrations that occur in the lens due to affecting on the quality of the image formed by this lens and plays a vital role in determining the analysis ability of electron microscope, that is given by the following relationship [23]:…”

The investigation of a study of each design included the calculation of its axial magnetic field the magnetization of the lens in addition to the magnetic flux density using Finite Element Method (FEM) at three different values of current density (σ = 2,4 and 6 A/mm2). So clearest values and behavior have been obtained at the value current density of (2 A/mm2). It is found that the best magnetizing properties, the highest value of magnetic flux and the lowest value of band width of the axial magnetic field strength have been obtained when the pole head shape length was of (1 mm). The effect of current density on the optical properties has been also studied, and it is found that optical properties have been improved also, and chromatic and spherical aberration values have been decreased significantly. Thus, lens was chosen as the best design among the proposed designs.

COVID-19 virus, which is a member of the coronavirus family, is a virulent virus that is transmitted by physical contact or air and results in death in infected people. People infected by the COVID-19 virus must be kept in quarantine in a closed area. Therefore, it is very important for the health of the individuals (patient, doctor, nurse, etc.) in the isolation room that, where the area kept closed is completely free of virus. This study was conducted to examine the flow dynamics of the air in the isolation chamber. With the simultaneous operation of the sanitized air machine and the ventilation in the room, it is aimed to investigate the virus killing effect of the air mixed with each other. The flow dynamics, velocity, temperature and turbulence kinetic energy of the air in the isolation chamber were examined. Investigations were carried out to ensure that the mixture of the two air in the room was better and distributed throughout the room.
