The future transportation

In today’s world we give more importance for time than anything. If you travel from new york to los angeles by plane it takes 6 hrs to cover 3950 km distance. If we develop faster mode of transportation we can reach in 31.5 mins at an average speed of 8350 km/hr.We wonder how it is possible? but it is possible in the future. This system is called “planetarium”. A magnetically suspended tram moving through a pipeline at a low pressure. The thrust is generated by the pressure difference at the other end of vehicle. The tube inside which the vehicle moves is sectioned into locked compartments, all the compartments are at a different pressure so that pressure falls in the outward direction. These pressure drops propel the vehicle until compartment no. 50 for example. The pressure is only 98 pa. which corresponds to atmospheric pressure at an altitude of 50 km. Thus fairly low pressure is established for the remaining length of tube & the accelerated vehicle pierces at an enourmous speed. When the vehicle is on way back, the pressure settings are obviously reversed. The acceleration down the initial section is limited by passenger comfort. The contraction of such a system is an extremely involved energetic challenge. The most challenging problem is the concentration of the scheduled large diameter pipeline extending for a greater distance. This is possible for the oil & gas transportation. The construction of tube carrying wheel less vehicles at the space speeds may be possible tomorrow.

Military Communication

The world of communication made the world as a global villege. Most of the communication developed for the purpose of Military usage in the world war 2. The advanced radio design development & production in frequency from 1.5 mhz to 5 Ghz. It features high speed built in crypto algorithm. Cryptology is the study of military codes. Written in theirion military codes and electronic counter measure techniques.
1) Frequency hopping
2) Direct response

For reliable communication under severe battle environment. Quality modems to serve the increasing demand for command, communication, control, computer, intelligence, survelliance and reconnaisance. (C4ISR). Multichannel line of sight frequency hopping wide band radio equipment. for reliable inter command parts communication.

Tactical Terminals- Computers & communication controllers from HQ to any point in the battle space.

Vibration Test for Satellites & Space Shuttle

Before launching the satellite & space shuttle it is the most important test. I am writing the article for the sake of budding youngsters. Without doing the vibration if satellites are launched all the components or parts will break up & comeout of the capsule. The world runs on mechanical vibrations. Even a quartz clock runs on vibrations when an electric current pass through the piezo electric crystal, crystal vibrates. This is the principle of quartz clock. Vibration is strong phenomenon on earth. When PSLV lifts off the spacecraft or satellite carried by PSLV experiences 15g condition (‘g’stands for acceleration due to gravity). The condition of accelertion due to gravity is tested by accelerometer. 120 accelerometer are placed near the instrument of space shuttle & satellite so that each part could be tested. If a part or component gets cracked by the vibration while testing they will replace the part & component.

The Banned drugs in the sports world

Now the Beijing olympics is over, the cry of banned drugs in the olympics is less compared to last 3 decades. But still there are some cases of performance enhancements drugs in the sports world. They are stimulant substances which act on the brain stimulating both mentally & physically. They increase alertness, competitiveness & agression & help to combat fatigue making athletes feel stronger & more energetic. These days stimulants can increase BP & body temperature  & create irregular heart beat & may result in cardiac arrest & stroke.

Examples of Banned Stimulants

1. Amphetamine
2. Salbutamol
3. Mesocarb
4. Terbutaline
5. Ephedrines
Steroids (Anabalic Steroids)

Anabalic means body building mimic the effects of male sex harmone testrosterone by stimulating the muscle & bone cells to make new protein. Sportsman can able to train harder & longer. The side effects are

1) male feature in women
2) loss of fertility
3) impotence & damage to kidneys
4) increase the bp & harden the artery

Examples of Anabalic steroids

1) Stanozolol
2) Nandrolone
3) Androstenedione

3) Diureties: It helps to eliminate the fluid from the body & used to treat the high bp.They increase the production of urine & reduce tissue swelling. Diuretes are mmisused by sportsmen to reduce weights and as a making agent by diluting urine.

The side effects are

1) severe dehydration
2) Kidney Damage
3) Cardiac Arrest

Chandrayan Of India

Although Moon was explored in the 1969 by the Americans it is very much less we learnt about the Moon. Moon is a very mysterious place for scientists. It is Indians turn to explore the moon. Indians are launching polar satellite launch vehicle into the orbit. Polar orbit is 800 to 1500 kms from the earth. Indians are launching unmanned mission into the PSLV orbit. launching depends on the exact positioning of the earth sun & the moon. Indians wants to explore the poles of the moon.  Polar region of the moon is a mysterious place of atmosphere. Helium gas & gravitational forces need to be studied properly. The space craft is tested on space simulator.
1) Vibration test – before launching the space craft to the moon vibration test carried out on spacecraft. Space shuttle should with stand the 16 tonnes of vibration.

2) Space shuttle should tolerate a noise similar to noise produced by 10 jet engines.

3) Temperature test – It should withstand the temperature of 100′c

Space shuttle should map systematically topography of the moon and chemical 7 micrological mapping of moon to understand the process of formulation & chemical evolution of moon.
