India's Advanced Communication Satellite GSAT-7 Launched Successfully


India's advanced multi-band communication satellite, GSAT-7, was successfully launched on August 30, 2013 by the Ariane-5 launch vehicle of Arianespace from Kourou, French Guiana. Ariane-5 precisely placed GSAT-7 into the intended Geosynchronous Transfer Orbit (GTO) after a flight of 34 minutes 25 seconds duration. 

As planned, ISRO's Master Control Facility (MCF) at Hassan in Karnataka started acquiring the signals five minutes prior to the separation of GSAT-7 from Ariane-5 launch vehicle. The solar panels of the satellite have been deployed and they are generating power. Initial checks have indicated normal health of the satellite. 

The present orbit of the satellite will be raised to Geostationary Orbit of about 36,000 km altitude through three orbit raising manoeuvres by firing of GSAT-7's Liquid Apogee Motor (LAM). Preparations are underway for the first firing, planned in the early hours of August 31, 2013. The satellite will be placed in the Geostationary Orbit by Sep 04, 2013.

Monsoon Diseases

During rainy season some want to enjoy watching the weather from the comfort of their homes eating their favourite ‘pakoras’ and sipping a hot cup of ‘chai’, while others want to go out and enjoy the rains. Though following a scorching summer the rain ushers in new lease of life, it sometimes brings with it some deadly diseases.

Following are the most common diseases, their symptoms and some suggestions to prevent them during the rainy season.

Malaria

• This is the most dangerous disease in India with a very high number of deaths credited to it. The disease is spread by Female Anopheles mosquito. A large number of cases are reported during the rainy season as water logging provides conducive conditions for mosquitoes to breed.

• Fever at regular intervals, bouts of shivering, muscle pain and weakness are the general symptoms of Maleria.

• Since this disease is spread by mosquitoes the best prevention is to keep the surroundings clean and mosquito-free. Make sure that water does not stagnate in your area as mosquitoes breed in stagnant water. Use DDT in the drains near your home. Use of mosquito repellents and nets is highly recommended. Do not ignore any symptoms of malaria and consult your doctor immediately if you feel any sign of the disease.

Cholera

• Cholera is caused by contaminated food and water. Also poor hygienic conditions help the spread of the disease. It normally spreads in places with poor sanitation facilities.

• Severe diarrhea with watery stools is the most common symptom of Cholera. There could also be vomiting with immediate water loss and muscle cramps.

• Keep the drinking water clean and boil it before using. Maintain personal hygiene and good sanitation. It is advisable to get vaccinated as it gives immunity for almost six months.

• Oral rehydration should be given immediately for patients suffering from Cholera.

Typhoid

• Typhoid is another highly infectious disease that spreads during the monsoon season and it is also caused by contaminated food and water.

• The most common symptom of this disease is prolonged fever. Severe pain in abdomen and headache can also be the symptoms.

• This is a highly communicable disease so the patient should be isolated from the rest of the family. Advance vaccination may also help prevent it. High intake of fluid is advised to patients to prevent dehydration. Since this disease has a tendency of relapsing precautions should continue even after apparent recovery.

Hepatitis A

• Hepatitis A is generally caused by flies. It can also spread by coming in direct contact with the patient.

• The symptoms are similar to those of flu including high fever along with headache, pain in joints and vomiting.

• The most important prevention of this disease is vaccination. This vaccine is available at all the government and private hospitals. Complete bed rest and a high calorie diet is advised to the patient.

Common Cold

• Common cold is the most common disease that spreads easily during rainy season. • Constant sneezing, sore throat and fever are the common symptoms of the disease. • The easy way to prevent common cold is to avoid catching it. But if at all it catches you, treat yourself with a glass of hot turmeric milk. Gargles with warm water give relief to your sore throat. If things don’t improve you may like to see a doctor.
