National income September 3, 2009

Filed under: BITS,Do u Know,gk — swapsushias @ 6:35 pm

Concept of national income

  • National income is calculated by CSO – CENTRAL STATISCAL ORGANISATION
  • FROM 2005 BASE YEAR FOR ANY CALCULATION OF NATIONAL INCOME IS TAKEN AS 1999-2000
  • BEFORE 2005 BASE YEAR WAS 1993-94
  • GDP- GROSS DOMESTIC PRODUCTION
  • GNP-GROSS NATIONAL PRODUTION
  • NNP NET NATIONAL PRODUTION
  • NDP NET DOMESTIC PRODUTION
  • GDP- GDP IS THE SUM TOTAL OF MARKET VALUE OF ALL FINAL GOODS & SERVICES PRODUCED INSIDE THE NATINAL TERRITORY
  • GNP=GDP+INCOME FROM ABROAD
  • DEPRECIATION VALUE OF CONSUMPTION OF FIXED CAPITAL =GDP-NDP
  • NNP=GNP- DEPRECIATION
  • NATIONAL INCOME =GDP-NET TAXES
  • NET TAXES =INDIRECT TAXES –SUBSIDIES
  • NATIONAL INCOME IS CALCULATED IN TWO WAYS
    1. ON CURRNT PRICES IN THIS YEAR PRODUTION IS ALCULATED BY CONSIDRING PRESENT PRICE OF GOODS AND SERVICES
    2. ON CONSTANT PRICES IN THIS PRICE ON THE BASE YEEAR IS TAKEN AS THE REFERANCE TO CALCULATE THE NATIONAL INCOME

PER CAPITA INCOME = NATIONAL INCOME/ POPULATION

PPP PURCHASING POWER PARTY INDEX IS CONSTRUCTED BY TAKING INTO ACCOUNT WHAT A UNIT CURRNCY CAN PURCHASE IN ITS OWN COUNTRY

The general science September 3, 2009

Filed under: BITS — swapsushias @ 6:24 pm


The general science

Topic the study cell(PART ONE)

There are three main branches of biology

· Microbiology

· Botany

· Zoology

Term biology was given by Lamarck and Treveranus

Some well known father’s of different biological fields are

Father of biology Aristotal

Farther of zoology Aristotal

Father of botany Theophrastus

Father of microbiology Leeuwenhoek

Father of medicine Hippocrates

Indian Father of medicine Dhanvantri

Cell

· Robert hook was first to discover dead cell

· Living cell was first discovered by Leeuwenhoek

· Cell is basic structural and functional unit of life

· Cell is divide In two parts

Prokaryote

This is the cell type in which there is no definite nucleus as DNA not surrounded by a membrane

These have no the membrane bound organelle except ribosome

These have cell walls made up of murein

Eukaryote

These cells contain a membrane bound nucleus and have nucleolus & chromosomes

These has all cell organelles

Cell wall mainly are made of cellulose

Basic cell structure

Cell is mainly composed of three parts

1. protoplasm

2. organelle

3. nucleus

Protoplasm

It is the living fluid of the cell

It is called the physical basis of life by huxlay

It contains 75% OF WATER & other 25 % of different substances containing living and nonliving molecules

Cell organelles

Endoplasmic reticulum

Complex system of membrane bound tubules and flattened sacs

It has two types

  1. rough endoplasmic reticulum
  2. smooth endoplasmic reticulum

On the rough endoplasmic reticulum there are too many ribosome attached on its surface

rough endoplasmic reticulum is completely engaged in protein synthesis so most abundant in cells engaged in active protein synthesis

while smooth endoplasmic reticulum is mainly associated with cells engaged with lipid metabolism

Ribosome

  • They are the smallest organelle of the cell
  • Site for the cell protein synthesis
  • They are of two type
  • 70 S in prokaryote and 80 s in eukaryote
  • They are not surrounded by any membrane

 

क्या पता है आपका डिफेन्स के बारे में September 2, 2009

Filed under: BITS,Indian military — swapsushias @ 2:07 pm

1. The Indian Army has used tanks originally designed and built in many countries. Which of these countries has India never bought tanks or a license for production?


Your Answer: Germany

India’s tank arsenal, some of it inherited from the British World War 2 stock post-Independence, has included tanks from the above countries, except Germany. While British and French tanks, such as the Centurion and AMX-13, plus a few vintage Shermans, formed the pride of Indian armour in the 50′s and 60′s, Soviet tanks such as the T-55, T-62, T-72 (in large numbers) and most recently the T-90, have formed the majority of India’s armoured corps since the 70′s.






2. What is the nickname of the Vickers MBT operated by the Indian Armor in the 1970s and 1980s?


The correct answer was Vijayanta.

After the success of the British Centurion tanks against the much-touted M-48 Pattons of the Pakistani Army, in the fields of Punjab in the 1965 Indo-Pak War, the Indian Army decided to go for British made Mark 1 Vickers’ MBT, which was locally renamed as the “Vijayanta” (Victorious tank). Although this tank is in the process of being phased out, there are still 700-800 in inventory, although they are unlikely to be in active use for long. The other options are T-72 (Ajeya), T-90 (Bheeshma) and BMP-2 (Sharath)






3. What is the name of the indigenously developed third generation anti-tank missile to be inducted into the Indian Army in the nest couple of years?


The correct answer was Nag.

“Nag is a third- generation “fire and forget” anti-tank guided missile with a range of 4 to 6 kilometers. Nag can be mounted on an infantry combat vehicle and helicopter launched version of Nag is also available.
Nag is a third generation anti-tank missile system with “fire and forget” and “top attack” capabilities. Capable of defeating modern armour, Nag uses Imaging Infra-Red (IIR) guidance having both day and night capability. The state-of-the-art Imaging Infra Red homing guidance system has lock-on-before-launch capability for day and night operation ” (source:http://www.globalsecurity.org/military/world/india/nag.htm)
It is said to be superior to the American “Javelin” ATGM in terms of range. It was developed as part of the integrated missiled development plan, which also includes MRBMs, IRBMs and SAMs.






4. The military draft has been imposed 4 times in Independent India.


The correct answer was False.

India has never imposed the draft since Independence despite having been involved in three and half declared wars with Pakistan, one with China and numerous insurgencies in the North East and Kashmir. It is an all volunteer force of nearly a million men.






5. This regiment, raised in 1949, was the first all class regiment, made by combining the senior most battalions of four senior most infantry regiments. It is the most elite regiment of the Indian Army. Which regiment am I referring to?


The correct answer was Brigade of the Guards.

“The Brigade of the Guards has been accorded the senior position in the infantry and takes rank first in the arm. Punjab, Grenadiers, Rajputana Rifles and Rajput Regiments provided the battalions that started the Guards. Succeeding battalions were raised by direct recruitment. It’s battalions have formed part of United Nations forces in Gaza (Middle East) and Angola. In addition to the 19 infantry battalions, the Regiment also has two Territorial Army battalions and one Rashtriya Rifles battalion.
Guards have made a special name for themselves in the Indian Army, by their combat record and excellence in almost all fields of war and peace. Mechanisation of these battalions is likely to be completed, as only four battalions were left in March 1999. The mechanised battalions of the regiment have already acquired BMP-2 ICVs, anti-tank guided missile launchers and other equipment utilised in mechanized forces. The 19 Guards operates anti-tank guided missiles, while four other battalions operate in the Recce & Support role. These four fight right on the border as frontal support units to the main battalions.”

6.


The Punjab regiment is one named after a REGION, the rest are based on CASTE. Among the other regiments based on a region are: Assam Regiment, Rajputana Rifles, Bihar Regiment, etc.






7. Which regiment has the honour of having the most number of Param Vir Chakra (India’s highest medal for gallantry) awardees


The correct answer was Grenadiers Regiment.

The Grenadiers Regiment, one of the oldest regiments of the Indian Army, has had three PVC awardees in its ranks. Company Quarter Master Havildar Abdul Hamid, 4th Grenadiers was the first recipient of the Param Vir Chakra (Posthumous) for the Regiment in 1965 and the second recipient to get the Param Vir Chakra was Major Hoshiar Singh, 3rd Grenadiers in 1971. Hoshiar Singh retired as a Colonel from the Army and passed away in 1998. The third recipient of this coveted medal, but certainly not the last, was Grenadier Yogender Singh Yadav, 18th Grenadiers in 1999.

8. This weapons system was under a cloud of controversy for the greater part of the 1990s costing Rajiv Gandhi the Prime Ministership, on allegations of corruption in the acqisition of these systems. However, the Kargil War in 1999 showed that these weapons systems were actually well worth the trouble.


Your Answer: Bofors guns

The Bofors gun purchase was shrouded in a huge controversy after the discovery of certain incriminating documents, which purported that Rajiv Gandhi had received kickbacks for making the deal come through. Also implicated, in a trial currently underway, are the British-Asian businessmen, the Hinduja brothers. However, the Kargil saw the effectiveness of the gun proved tremendously, and a tentative order has been placed for more.






9. Which is the oldest armoured regiment in the Indian Army?


The correct answer was President’s Bodyguards.

The President’s Bodyguard (PBG), as it is known today, was raised in 1773 at Benares, by then Governor General Warren Hastings, with a strength of 50 picked troopers and horses. This nucleus of the Bodyguard was later augmented by another 50, provided by Raja Chet Singh of Benares, bringing the overall strength of the Bodyguard up to 100 horses and men by the end of that year. The establishment of the Regiment varied through the years, being augmented in times of war and it attained its maximum strength of 1929 all ranks, in the Army List of 1845, just prior to the First Sikh War. The PBG continued to be a select cavalry unit, primarily for the personal and battlefield security of the Governor General.
The President’s Bodyguard has the unique distinction of being the only military unit in the Indian Army, privileged to carry the President’s Silver Trumpet and Trumpet Banner.”

10. Who was appointed the Chief of Army Staff of the Indian Army in June 2005?


The correct answer was Joginder Jaswant Singh.

“General Joginder Jaswant Singh assumed charge of the Indian Army, as the 22nd Chief of Army Staff, on 31 January 2005. Hailing from a family of warriors, he is a third generation soldier. His grandfather served in the 1/67 Punjab Regiment during the Second World War and his father, Colonel J.S. Marwah served in the Indian Army from 1943 to 1973 and is also a veteran of the Second World War. Born on 17 September 1945 in Bahawalpur (now in Pakistan), he is an alumnus of the National Defence Academy (NDA) and was commissioned into the 9 Maratha Light Infantry on 02 August 1964″

TYPES OF WATER REACTORS August 28, 2009

Filed under: BITS,Science And Tech — swapsushias @ 5:25 pm

1. PWR – PRESSURIZED WATER REACTORS
- these are reactors cooled & modulated by high pressure liquid water. they are the majority of current reactors, & are generally considered the safest & most reliable technology currently in large scale deployment, although 3 mile island is a reactor of this type. this is thermal neutron reactor design, the newest of which are Advanced Pressurized Water Reactor.

2. BWR – BOILING WATER REACTOR
- these are reactors cooled & moderated by water, under slighlty lower pressure. the water is allowed to boil in the reactor. the thermal; efficiency of these reactors are higher, simpler, potentially more stable & safe. these reactors make up a substantial of modern reactors. this is thermal neutron reactor design. the newest of Advanced Boiling Water Reactor & economic simplified boiling water reactor.

3. PHWR – PRESSURIZED HEAVY WATER REACTOR
- this is Canadian design, these reactors are heavy-water cooled & moderated pressurized water reactors, instead of using a single large pressure vessel as in a PWR, the fuel is contained in hundreds of pressure tubes. these reactors are fuelled with natural uranium & are thermal neutron design. PHWR can be refueled while at full power. this have been built in Canada, Argentina, China, India, Pakistan, Romania, South Africa.

4. RBMK – REAKTOR BOLSHOY MOSHCHNOSTI KANALNIY (high power channel reactor)
- a Soviet Union design , built to provide plutonium as well as power. RBMK are water cooled with a graphite moderator , are in some respects similar to CANDU in that they refuelable on-load & employ a pressure tube design instead of a PWR-style pressure vessel. RBMKs were very unstable & too large to have containment buildings making them dangerous in the case of accident.

THE CHERNOBYL PLANT HAS 4 RBMK REACTORS :
1. AGCR – Advanced Gas Cooled Reactor
2. GCR – Gas Cooled Reactor
3. Monju
4. Aqueous Homogeneous Reactor.

ADVANCED REACTORS :
- integral fast reactor
- pebble bed reactor
- high temperature gas cooled reactor
- SSTAR – small, sealed, transportable autonomous reactor.
- suboritical
- thorium based reactor

GENERTION IV REACTORS :
* gas cooled fast reactor
* lead cooled fast reactor
* moltan salt reactor
* sodium-cooled reactor
* super critical water reactor.
