· Causes and Treatment. The main causes of rhonchi are obstructions or increased secretions in the larger airways of the lungs. They can be heard in .
· This paper investigates the influence of wheel eccentricity on vertical vibration of suspended monorail vehicle based on experiment and simulation. Two sets of tests are conducted in the first Chinese suspended monorail, and the tested acceleration is analyzed and exhibited. A multibody dynamic model of the suspended monorail vehicle is established to simulate the vertical vibration of .

· 1. Introduction. Vibration of equipment has been a severe problem in Hydro Power Stations (HPS) from the very beginning of power generation. Failure of the equipment due to vibration causes shut down, or sometimes, even a disaster in hydro power station (HPS), .VCM has to be done to examine the performance of such equipment online automatically and to know the status of complex .
Data on human exposure to vibration has been incorporated into AS2670: Evaluation of human exposure to wholebody vibration. Vibration exposure limits are given as a function of: • Direction of motion, either horizontal or vertical. • Frequency of vibration. • .
Oedema is one of the fundamental features of heart failure, but the pathophysiology of oedema varies. Patients present along a spectrum ranging from acute pulmonary oedema to gross fluid retention and peripheral oedema (anasarca). In patients with pure pulmonary oedema, the problem is one of acute h .

· Paronychia Symptoms. Paronychia typically begins with a few days of pain, tenderness, and swelling of the finger followed by a collection of pus under the surface of the skin and/or nail. This will eventually form an abscess from which pus can be drained.
· Other reasons why acquired jumpy vision occurs include effects of certain mediions, alcohol intoxiion, head injury and stroke. Horizontal and vertical shaky vision can be due to either congenital or acquired reasons. What are the Symptoms of Jumpy Vision
Whole body vibration (WBV) is a generic term used when vibrations (mechanical oscillations) of any frequency are transferred to the human are exposed to vibration through a contact surface that is in a mechanical vibrating state. Humans are generally exposed to many different forms of vibration in their daily lives.
