The range of the radar horizon dependson the height of the antenna and on the amount of bending of the radar wave.The bending is caused by diffraction and refraction. Diffraction is a propertyof the electromagnetic wave itself. Refraction is due to the prevailingatmospheric conditions.
Anaerobic bacteria, or anaerobes, are bacteria that do not need oxygen to live. In humans, these bacteria generally live in the gastrointestinal tract, but they may also be found in other places outside the body, including in the soil and water, in foods, and in animals.
Antibiotics for anaerobic bacterial infection include metronidazole and clindamycin. These drugs are used to fight bacteria that thrive in environments devoid of oxygen. Combo drugs such as Piperacillin/tazobactam, ampicillin/sulbactam, and amoxicillin/clavulanate are effective as well.
