Pocket Dosimeters ::

Pocket Dosimeters is one of the radiation monitoring instruments. It is like fountain pen size structure. These Dosimeters are small and portable so that can be kept in pocket. It has a built in electro meter coupled with electrical chamber. The ionization chamber has separate charger to charge the internal devices. Self reader and charge reader helps to read the instrument very efficiently. It should be initially charged for effective reading and measurement. Quartz fiber is used for zero scale reading.

BIO-GEO CHEMICAL CYCLE ::

Bio-geo chemical cycle takes place continuously without any break. This cycle is highly essential for the existence of life in earth. There are two types of biogeo chemical cycle namely gaseous cycle and sedimentary cycles. Those that take place in the atmosphere are known as gaseous cycle and those which take place in the ground and deep inside the ground are known as sedimentary cycles. Examples of gaseous cycle include carbon cycle and nitrogen cycle. Example of sedimentary cycle includes phosphorus cycle.

Electroretinography ::

The Electroretinography interprets the electrical activities in the eye. It records all the electrical activities and sends to the sense organs. The external retina is associated with the cerebral cortex. The potentials are easily measured with the positive relative action. Both the interior and exterior sections are measured accurately. The potential changes in the distant electrodes leads to the contact lens. The eye ball illumination has large variations for every potential changes. The slight variations are recorded accurately with care.

Heart Sounds ::

The heart sounds and murmurs are divided into various categories such as low range, medium range and high range. The low range heart sounds in the range of 10 – 60 hertz. It is represented by fourth and third heart sounds. The medium range heart sounds in the range of 60 – 150 hertz. It is represented by second and first heart sounds. The high range heart sounds in the range of 150 – 1000 hertz. It is represented by diastolic, snaps and clicks in the pulmonary insufficiency.

Its summer and this season's special is: obviously strokes and hemorrhages! The common misconception prevalent among people regarding these two brain attacks is that they occur only for people with high blood pressure and bad habits. This is partly true since most patients afflicted with this condition are hypertensive. Secondary reasons include drug abuse, smoking and alcohol consumption. But strokes can affect anyone in any age group. Even in their mildest forms they can cause serious damage and take a long time to resolve. If the patient is rushed to the hospital within a short time of the onset of the stroke, most of the damage can be reversed. Excellent healthcare and emotional support of family and friends will go a long way in accelerating the recovery of the patient. But as the saying goes, prevention is better than cure. One has to be careful especially during summer when sun strokes are common. It is advisable to drink gallons of water and not shy away from carrying umbrellas! Blood pressure should be checked from time to time. Healthy diet and exercise can work wonders. Most important of all, keep your mind stress free and relaxed. Meditation and yoga will help. And the most terrifying aspect of brain attacks is that they make you totally dependent on others! Hence  it is better to take care of yourself first.
