There Are Some Uses Of GPS In Several Studies

Lots of research has been done by experts to maximize the use of GPS. Even today, GPS with high accuracy can be used to monitor ground movement, the idea is only mm in a year. Monitoring ground movements are useful for estimating earthquakes, both volcanic or tectonic movements. This technology can even be used in business, just like the geo fencing features for the location-based marketing campaigns.

The following are some examples of the use of GPS in several studies:

1. Geodynamics by placing monitoring points in selected locations, periodically or continuously to be carefully coordinated using the GPS survey method.

2. Ground deformation on the body of a volcano by placing several points in selected locations, its coordinates are carefully determined using the GPS survey method. By studying the pattern and speed of change of coordinates from these points from one survey to the next survey, the characteristics of the ground deformation in the body of the volcano can be calculated and studied further.

3. Study of the ionosphere and troposphere. GPS satellites emit electromagnetic wave signals that before being received by the GPS receiver antenna will pass through the medium layers of the atmosphere, namely the ionosphere and troposphere. In both of these layers, the GPS signal will experience interference (bias) so that the calculated distance will give a value that contains an error. Distance is used to calculate the position of a point. In the scope of GPS studies, these two layers become a bias that must be corrected before determining the position of the point.

4. Oceanographic studies using the GPS buoy system are used, among others, for the determination of offshore tides, beach tides, studies of current patterns, EWS tsunamis, and others. GPS can provide position accuracy up to a centimeter or millimeter accuracy. To achieve high accuracy using GPS in the GPS Buoy study, differential kinematic methods are used both in real-time (RTK) and cinematic post-processing. For some cases commonly used Differential GPS (DGPS).

5. Earthquake studies. GPS data can properly see the deformation that accompanies the stages of the mechanism of an earthquake. The study of the stages of this earthquake mechanism will be very useful in evaluating the potential for earthquake natural disasters, to improve mitigation efforts in the future.

You Can Do These 2 Ways To Deal With Hypothermia

Hypothermia can occur anywhere, especially in cold places like mountains and snowy areas. If not immediately given the right treatment, hypothermia can quickly attack the functioning of the heart, lungs, and other body organs until finally fatal. That’s why if you want to avoid hypothermia at home, you might consider installing a gas furnace at home, and you can read the goodman gas furnace reviews if you’re looking for a recommended furnace.

Now, to prevent hypothermia from getting worse, you can provide help in the following 2 ways:

1. The first aid

Regardless of the underlying cause of hypothermia, giving first aid is important before the patient gets medical help.

Move to another place that is warmer and drier. If this is not possible, it is better to protect people who have hypothermia from exposure to wind and worse cold.

Remove all wet clothing that may be worn by sufferers.

Give warmth by covering the entire body of the person using a thick blanket, thick layers of clothing, sleeping bags, or anything that can warm the victim. Don’t forget to lay their bodies on a thick blanket or another mat that can give warmth.

You can use a warm compress, but avoid applying it to the arms and legs. How to overcome hypothermia will actually make the core body temperature decreases. Instead, apply warm compresses to the neck area or groin where the main artery is located.

Do not apply heat material directly to the skin, such as hot water or heat lamps without passing through an intermediary. Besides damaging the skin, high heat can disrupt the heartbeat.

If the hypothermia patient is conscious, hot drinks can be given.

Always monitor his breathing and heartbeat.

2. Medical treatment

How to deal with hypothermia with medical generally intended to restore body temperature to normal.

Apply CPR (cardiac resuscitation) technique if breathing suddenly stops.

Simple external heating. By giving extra warm clothing or taking off the patient’s clothes, then replace them with other clothes that are warmer.

External warm-up active. By using a heater, for example, a warm bottle or mask that already contains warm air, so that body temperature can rise again.

Internal heating. By giving intravenous fluids (infusions) into the body, including the chest and stomach, to help provide a warm feeling to the body.
