Cough is one of the commonest symptoms in childhood as well as at any age. It is important to understand that coughing is quite a normal act, as it is one of the body’s ways of protecting the bronchial tubes and lungs. Any irritation of the bronchial tree or the trachea excites a reflex one cough. There are two main causes of this irritation. Firstly, it may be due to mucus which comes down the back of the nose. The cough reflex is to prevent the entering of mucus into the bronchial tubes. Secondly, infection may cause inflammation of the trachea and this produces the cough reflex.
Many children who have a persistent cough have no disease in their chest. When the doctor examines such a child with his stethoscope there is no abnormality to be heard. However, in some children coughing is due to impairment in the chest itself. The cough is an expression of the normal defences of the chest, but in this case the bronchial tubes are inflamed.

A man 34-years of age had symptoms of bronchopulmonary disease, cough and fever which were controlled by penicillin. The X-ray examination of the chest showed a cavity in the left lung. The examination of the sputum for tubercle bacilli was negative. Two months later the patient re-entered the hospital, complaining of loss of weight.
The bronchopulmonary symptoms had become worse. He also had general cutaneous hypersensitivity and, for the preceding four days, constant bad headaches and left hemiparesis. The cerebrospinal fluid was normal. Within four days meningitis developed. The patient died in coma. An isolated small abscess of the upper lobe of the left lung and an isolated abscess of the right cerebral hemisphere were found at necropsy.

A delicate heart operation was performed in a hermetically sealed high-pressure chamber at the Moscow Research Institute for Clinical and Experimental Surgery.
The operated man was 48-years old. He had been hardly able to move because he was suffering from a serious congenital valve defect.
Now this operation is considered not a very complex one. But in this patient there was a serious risk of blood clotting in the brain.
The risk became quite insignificant when the operation was performed in the high-pressure chamber. At normal air pressure the amount of oxygen in a patient’s blood remains unchanged even if he breathes in pure oxygen. In a pressure chamber the oxygen amount in the blood increases considerably. In a pressure chamber the surgeon is able to operate with greater freedom on vital organs such as the brain, heart or blood vessels.
But it is very hard to work under high pressure. When operations are performed at seven or eight atmosphere pressures, the operation can only last two and a half hours. The personnel in the chamber have to be changed.

Power dividers serve a multitude of circuit and system applications, from amplifiers to radar receivers. The power divider is housed in a hermetic enclosure with stainless-steel female SMA connectors. As these stripline power dividers feature such small physical dimensions, more than 20 power dividers can be fabricated from a single substrate. Unit-to-unit amplitude tracking is specified as better than ±0.6 dB, while standard unit-to-unit phase tracking is better than ±6 deg. at 18 GHz.
Insertion loss (in excess of expected power-division losses) is less than 2.0 dB.
The four-way power divider boasts amplitude balance of better than ±0.4 dB. Phase balance is better than ±5 deg. Designed to handle input power levels to 1 W CW, the power divider supports wide-dynamic-range signal processing.

For use in broadcast and communications satellite receivers, the series of microwave local oscillators feature the smallest, lightest designs in the industry, weighting 4.4 g and measuring 7.5 mm tall. They offer a 1.9 cc volume. There are six models; samples are available. This one operates at 10.678 GHz. The 2nd covers 11.200 GHz, the 3rd works at 11.300 GHz and the 7th accommodates 10.750 GHz. The 8th works at 10.873 GHz, the 9th handles 10.990 GHz. The excellent performance eliminates the need to adjust the high frequency. As a whole, the modules make it possible to create a miniature outdoor unit for satellite broadcasting. They are suitable for converters in flat antennas, and mount easily on converters.
