Not done yet :

So ESE 2017-Pre ( obviously a new word has been introduced by killer institute UPSE ) is over.

Some of you have done well at this stage and most of you have failed to your expectations ( same could be concluded for SSC-JE ☺). But the under covered fact is, that none of you know the final result, if you have done well don't be over confident bcz enemy power is still unknown 😉, so just continue your hard work✍ to clear next two hurdle 👍.
Now coming to mass people who are destined to overcome the mistake they have committed in this exam.
Which is possible only if you ( if you are one among them ) have trust in these Power Points:

1- There is nothing like permanent in this universe ( will fight next time 💪 ).
2- There is definitely a better one ( Har Sher ka Sava Sher hota hi hai🐯 ).
3- It was not the end of world ( Duniya rukati nai bhai shahb )
4- There are plenty of fish in the water, if not this one, choose other one ( be wise ).
5- Accept your fault and learn from them. ( Imandaar bano dost 😉 )
6- Reorder yourself.
7- Have patient & consistency ☺.
8- Have confidence in yourself.
9- Be single goal oriented ( most important ☺ ).
10- God have plan for every one and is with everyone 👍.

Objective question practice session :✍✍

So, you wanted it, we planned it and soon we are going to start it ☺.

Definitely practice and consistency are the two key to be successful in any field💪. keeping this in mind and observing the upcoming exams we have started to compile the best questions (subject wise) and it is being scheduled to be published as soon as possible.

On our side we will try our best to make  perfect sets of questions and from your side we are expecting the same level of hard work. Here we would like to tell that-

1- Don't try to substitute it with your books, it's just a supplementary material.
2- Go thoroughly through your books.
3- Solve solved and unsolved questions as much as possible.
4- Then try to solve questions posted on Linkupdots.
5- On day one you will get question set and on next day solution.

Linkupdots questions will be most likely to be the expected one in SSC-JE & SES-AE/JE exams and will help you to brush up your basic concepts.
So get ready to test your self 👍.

UNFCCC

United Nations Framework Convention on Climate Change (UNFCCC) created because of the Rio Summit/ Earth Summit of 1992.
It is an international treaty for reducing greenhouse gas emissions.
Now nearly every country on Earth is a party to the UNFCCC with few major exception like USA, Canada.

*So what was Rio Summit/ Earth Summit -
It was a United nations summit, held in Rio de Janeiro (Brazil) in 1992.
It led to creation of United Nations Framework Convention on Climate Change (UNFCCC)

The nations, who’ve signed UNFCCC convention, meet every year to discuss climate change strategy.
These meetings are called Conference of the Parties (COP)

Some notable COP :
COP 1 - held in Berlin ( Berlin Roadmap ).
COP 3 - held in Kyoto, Japan ( Kyoto Protocol ).
COP 7 - Marrakech, Morocco ( Marrakech accord ).
COP 8 - Delhi.
COP 13 - Bali, Indonesia ( Bali action plan ).
              -  Adopted REDD+
COP 17 - Durban, S.Africa in 2011.
COP 18 - Doha, Qatar in 2012.
              - Extended Kyoto Protocol for phase 2.
COP 19 - Warsaw, Poland
              - Warsaw international mechanism on loss and damage.
COP 21 - Paris
               - Paris Agreement.

RLV-TD

Reusable Launch Vehicle-Technology Demonstrator (RLV-TD)

India’s first winged body aerospace vehicle, called the Reusable Launch Vehicle-Technology Demonstrator (RLV-TD) was successfully launched from ISRO’s first launch

pad in Sriharikota 80 km off Chennai on the east coast at 7.00 am on Monday. The RLV-TD shuttle shaped like an aircraft was launched aboard the HS9 a seven-meter rocket with a booster, weighing 17 tons with nine tons of solid propellants. The rocket and shuttle made a successful flight of 91.1seconds and the burnout of HS9 followed.

The development of reusable launch vehicle has opened new gateways in conducting space experiments using conventional rockets. One major significance of reusable vehicle is its cost effectiveness. The new vehicle has the potential to cut down the actual cost of launching the rocket by ten times.

With the launch of reusable launch vehicle India has demonstrated the world that what India is capable of. Even though the launch vehicle is just a prototype, there is lot to be done in developing a fully fledged space shuttle.

In this flight, critical technologies such as autonomous navigation, guidance & control, reusable thermal protection system and re-entry mission management have been successfully validated.

With this successful mission India has joined the elite club of space-faring nations. The other countries are the USA, Russia and Japan, that developed and used RLVs for their space missions. This mission has enabled ISRO to successfully collect data and validate such critical technologies and systems as hypersonic speed, autonomous navigation, guidance and control, reusable thermal protection system, powered cruise flight using air-breathing propulsion and re-entry mission management. According to experts, the reusable vehicle technology will reduce the costs of launches in the future by 80% percent.

Differences between Bernoulli and S.F.E.E. ?

Well, Bernoulli's equation is a very simplified form of the actual energy equation derived by using control volumes around the fluid flow considering all possible variations including time and space. 

1) Bernoulli's equation doesn't account for any other form of work or energy other than potential energy, kinetic energy and pressure energy. For example, the fluid can flow through a pump doing work on it or a furnace heating a column of air. In these cases, you can't use the simple Bernoulli equation, as points before the area where work is being done on the fluid  and points after it have different Bernoulli's constants.

2) Moreover, Bernoulli's equation between two points is valid along a streamline only. This is because different streamlines have different Bernoulli's constant (although, this is rare and is not true when the flow is irrotational) 

3) For energy equation to be valid, the flow field need not be incompressible or non-viscous as is needed for Bernoulli's equation (unless you are using compressible Bernoulli flow equation and also adding the friction head to take care of viscous effects at the wall)

4) Further, the Bernoulli equation is generally used for steady and laminar flow. Energy equation written in its full glory takes care of variations in viscosity, density, pressure and velocity variation with respect to time and space. Written along with Navier Stokes equation, even turbulence can be accounted for.

Highlights of Union Budget 2016-17

Union Finance Minister has presented NDA government’s second budget.

According to the budget, the nine priority areas of the government are:

1. Agriculture and farmer welfare
2. Rural sector
3. Social sector
4. Education skills and job creation
5. Infrastructure investment
6. Financial sector reforms
7. Governance reforms and ease of doing business
8. Fiscal discipline
9. Tax reforms to reduce compliance burden

The government has also proposed rename Dept. of Disinvestment as Dept. of Investment and Public Asset Management. And fiscal deficit target has been retained at 3.5 per cent of GDP for next fiscal year in a big boost for stocks, currency and bond markets.
Who will get what?
Banks:

• Banks get a big boost: Rs 25,000 crore towards recapitalisation of public sector banks.
• Banking Board Bureau will be operationalised.
• More resources will be raised for additional capital if required.

Farmers:

• Farmers’ incomes to be doubled in five years by 2022. Total allocation for agriculture sector has been hiked to Rs. 35,984 crore.
• Big focus on rural distress: Government will spend a record Rs. 38,500 crore on rural jobs programme (MGNREGA).
• Rural road development schemes will get Rs. 19,000 crore, while another Rs. 20,000 crore will be used to fund irrigation schemes.

Infrastructure:

• Continued push for infrastructure development: The finance minister allocated Rs. 2.21 lakh crore for building road and rail infrastructure.
• Proposes to levy infrastructure cess of 1-4 per cent which will make cars costlier.
• 300 urban clusters to be set up under Shyama Prasad Mukherji Rurban Mission.

Black money:
A new amnesty scheme for those holding unaccounted money and assets has been announced. Those declaring undisclosed income under this scheme will have to pay 45 per cent tax.
Taxation:

• The government will not resort to retrospective taxation in future, while proposing a one-time tax dispute resolution for retrospective taxation.
• General anti avoidance tax rule (GAAR) will be implemented from April 1, 2017.

Vulnerable section:

• Target of disbursement under MUDRA increased to 1,80,000 crore.
• A “Krishi Kalyan” cess of 0.5 per cent has been proposed on all services effective June 1, 2016. This will make most of services (such as eating out, buying property, etc.) more expensive.
• Income tax relief for small taxpayers, more taxes for super-rich: Those earnings less than Rs. 5 lakh per annum will get additional relief of Rs. 3,000 on income tax, but the surcharge on super-rich (income of over Rs. 1 crore) has been hiked from 12 per cent to 15 per cent.
• Pollution cess of 1 per cent on small petrol, LPG and CNG cars; 2.5 per cent on diesel cars of certain specifications; 4 per cent on higher-end models.
• Government is launching a new initiative to provide cooking gas to BPL families with state support.
• LPG connections to be provided under the name of women members of family: Rs 2000 crore allocated for 5 years for BPL families.
