Section III. The form of imperative contrasting with hypothetical imperatives is the categorical imperative. This type of imperative purports to be true, or as is sometimes said, valid, apart from any presupposed end or purpose to be achieved by acting as it commands.ynthetic a priori. Kant claims that the categorical imperative is a synthetic a priori proposition. This means in part that we can know the categorical imperative that one ought to act only on maxims we can will to become universal laws independently of experience or any sensory observations.
The lung parenchyma is initially abnormal on chest radiographs in about one-half of patients. The percentage is higher on computed tomography which can detect disease when the radiograph is normal.
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. Lung cancer: Cancer may affect almost any part of the lung. 2  Most lung cancer is caused by smoking. 3  Tuberculosis: A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. 4  Chronic cough, fever, weight loss, and night sweats are common symptoms of tuberculosis.
