How can weakening rupee impact Economy and People

The rupee is not only the worst performing currency in Asia, its the second worst performing currency in the emerging markets. Here are 10 ways how a weak rupee impacts you:

 

Weakening Rupee and Its Impact

1. Morale dampener to people in India: Except NRIs, who stand to gain the most on account of the rupee weakness, most Indians are worried because of the rapid decline in the rupee.
2. Higher EMIs: Central banks around the world resort to higher rates to stem depreciation in the currency. That's because higher interest rates could bring in higher capital inflows necessary to finance current account deficit. That means living with high equated monthly installments.
3. Stuttering growth: India's GDP grew by 5 per cent in 2012-13, the slowest in a decade. The sharp depreciation in the currency and the RBI's likely tight monetary policy will lower growth expectations. 
4. Slowdown in foreign investment: Weak growth prospects will lead to a slowdown in capital inflows hurting investment in Indian economy and more so in the crucial infrastructure sector.
5. Rising inflation: Global commodities have 35 per cent weightage in India's wholesale inflation basket, and as the rupee weakness, the prices of these commodities go up. Nomura estimates that a 10 per cent depreciation in the rupee adds 60-80 basis points to headline inflation.
6. Higher fuel price: Petrol prices have been hiked twice this month. Such hikes will become a recurring feature as rupee weakens further. Crude, which is priced in dollars, is India's biggest import item and a depreciating rupee increases the cost of imports. The worst part is Indians will have to pay more for fuel even though global prices have hit a year-low.
7. Greater volatility in stocks: Foreign funds have sold net $6.7 billion (largely from bonds) from May 22 to June 24, 2013, Nomura says. The BSE Sensex has fallen nearly 8 per cent over the same period. Foreign funds are likely to sell more because the weakness in the rupee makes their investment unattractive. Shares in companies with higher FII holdings will be under pressure.
8. Corporate profits: Exporters will gain, but companies dependent on imported raw materials will see a sharp impact on their bottom line. A weak rupee also exposes companies with unhedged overseas loans.
9. Costlier foreign education: Those planning to go to the U.S. will have to shell out at least Rs. 2-4 lakh more for their expenses because of the sharp fall in the rupee, according to industry body Assocham estimates.
10. Costlier foreign travel: Travelling abroad will be costlier as you will have to pay more rupees to buy dollars for your overseas trip/vacation.

Battery - Working Principle - Types and why electrolyte is Used in batteries

A battery is a source of electrical energy. It is consisted by two substances, and represented by two electro-chemically active electrodes of different composition, both of which are immersed in an electrolyte that provides a conductive medium between them.

Principle of Batteries:

Electro-chemical reactions form the basis of conversion of chemical energy into electrical energy in batteries. The anode undergoes what is known as an oxidation reaction: during discharge two or more ions from the electrolyte combine with the anode to form a compound and release one or more electrons. Simultaneously, the cathode undergoes a reduction reaction.

Principle / Working  of Battery

Types of Battery:

What is the difference between primary and secondary battery?

Primary Battery: A primary battery can discharge once only. A primary battery internal structure is more simple, it doesn't have to accommodate reversible volume changes. The primary battery has bigger quality ratio and volume ratio than rechargeable battery.

Secondary Battery: a second battery is rechargeable. When discharge a rechargeable battery, its electrode volume and structure cause a reversible change. An external source of direct electrical current supplies electrons to the anode and removes them from the cathode, forcing the chemical reactions into reverse until the cell is recharged.

How a Battery works?

During battery discharge, the electrons released at the negative electrode (anode) travel through an external circuit and reach the positive electrode (cathode). 

What is the purpose of electrolyte in a battery?

Charge neutrality inside the battery is established by movement of ions in an electrolyte. Thus, the electrolyte is required to be a good conductor of ions. The electrolyte in a battery may or may not participate in the reactions occurring at the electrodes, but must support the reactions. 

For example, the electrolyte does not participate in the cell reactions in nickel-cadmium and lithium-ion batteries.

In the case of the zinc-manganese dioxide dry cells, a variety of neutral/alkaline electrolytes such as ammonium chloride, zinc chloride and potassium hydroxide can be employed.

Depending on the chemicals used, the zinc-manganese dioxide cell with potassium hydroxide electrolyte can be formulated as a primary cell or a secondary cell.

Why is only sulphuric acid used in batteries? Why not hydrochloric acid or nitric acid?

The working of the lead-acid battery (commonly used for starting-lighting-ignition operations in automobiles) involves 

• formation of lead sulphate by oxidation of lead at the anode and
• reduction of lead dioxide at the cathode.

Because the product of battery discharge is lead sulphate on both the electrodes, the total cell reaction is sometimes referred to as double sulphate reaction.

The formation of the lead sulphate products involves sulphuric acid, which is the electrolyte used in these batteries. During battery charge, lead sulphate is converted back to lead and lead dioxide, releasing sulphuric acid into the electrolyte.

Because sulphuric acid is 

• consumed during the discharge process and 
• released during the charge process.

The basic reactions in the battery involve uptake and release of sulphuric acid molecules, an electrolyte of sulphuric acid is used in these batteries.

Other acids that can be used in Batteries include:

It is, however, possible to use other electrolytes with the lead-lead dioxide couple. They include perchloric acid, fluoroboric acid, fluorosilicic acid, etc.

India's Longest Tunnel Inagurated

India's longest rail tunnel in Kashmir to provide a key link between the Kashmir Valley and Jammu region inaugurated by PM on 26/06/0213. The 18-km-long Banihal-Qazigund rail link, which includes the country’s longest transportation tunnel – over 11-km long – through the Pir Panjal range, was executed by Ircon at a cost of Rs 1,672 crore.

Tunnel - 11kms

The rail bridge between Udhampur and Banihal -- the train runs through the Pir Panjal mountain range -- is the highest in the world. An engineering marvel that took seven years to come up in a mountainous region. The tunnel has been constructed using New Austrian Tunnelling Method, which has been used for the first time on such a large scale in India

The new train also narrows the link gap between the 64,000-km rail network spread across the country and the 135-km network in the Kashmir Valley, which is yet to be connected with the vast Indian Railway network.

Indian Regional Navigation Satellite System - Indian GPS Overview - Mains

Indian Regional Navigation Satellite System: Overview

• The IRNSS will have a constellation of seven satellites
• the IRNSS-1A is the first of the seven regional, satellite-aided navigation systems built by ISRO.
• The satellite will be kept in geosynchronous Orbit at a height of 36000kms.
• The System is intended to provide an absolute position accuracy of better than 20 meters throughout India and within a region extending approximately 2,000 km around it.

Indian Regional Navigation Satellite System

• The IRNSS-1A will provide accurate information on the position of cars/trucks, ships and aircraft vis-à-vis their destination, with the help of a receiver.
• It could be an independent receiver, or built into a mobile phone, a car or a ship. The satellite can provide precise information when the aircraft is about to land on the runway.
• The pilot will know how far he is from the runway or at what height he is above the runway, with an accuracy of 20 metres.
• Unlike the Global Positioning System (GPS) which can be used anywhere, this is called a regional navigation system because it is available to users in India and the surrounding region. A highly accurate atomic clock is part of the navigation payload of the satellite.
• Thus, the IRNSS applications include terrestrial, aerial and marine navigation, disaster management, tracking of vehicles, guiding hikers and travellers, and visual and voice navigation for drivers.

Indian Regional Navigation Satellite System

The ground segment of IRNSS constellation would consist of a

• Master Control Center (MCC),
• ground stations to track and estimate the satellites' orbits and ensure the integrity of the network (IRIM), and
• additional ground stations to monitor the health of the satellites with the capability of issuing radio commands to the satellites (TT&C stations).

As per the 2008-Investment Pattern adopted by the EPFO, the body can invest up to 55 per cent of its huge corpus of over Rs 5 lakh crore in the state and central securities.

Early Vedic Age : Economy

Occupation: Society was pastoral, cattle rearing being the dominant occupational activity. Cattle were the chief measure of wealth and a wealthy man who owned many cattle was called 'gomat'.

The terms used for conflicts and battles in this period were

• gavishti,
• gavesana,
  
• gavyat,

The former literally means 'to search for cows'.

The Vedic god Indra was invoked to release these cattle. This reference suggests that cattle raids were common.

The raja or the chief is called the 'gopati' or one who protects cows. In the Rig Veda, Godhuli is used as a term for a measure of time. Distance is called gavyuti.

Literary references to pasture lands, cow pen, dairy products and domesticated animals are also found in most of the hymns and prayers.

Food Crops: . Apart from 'yava' or barley, no other grains are mentioned.

China’s Tianhe-2 emerges worlds fastest supercomputer

"Tianhe", meaning Milky Way. Breaks the U.S. monopoly in the field of strategic technology. Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, achieved processing speeds of 33.86 petaflops (1000 trillion calculations) per second on a benchmarking test.It earned the supercomputer the number one spot in the Top 500 survey of supercomputers, agency reports said.
 Five of the world’s 10 fastest computers are installed in the U.S., the survey said, with the two in China, two in Germany and one in Japan. Most of the Tianhe-2’s parts are developed in China, except for its main processors, which are designed by the U.S. firm Intel. But the U.S. still dominates the overall supercomputer rankings, with 252 systems making the top 500.

Supermoon and causes of its formation - its impact on earth

Supermoon’ is a situation when the Moon is slightly closer to Earth in its orbit than on average, and this effect is most noticeable when it occurs at the same time as a full Moon.

 the largest and brightest full Moon– 22^{nd June} 2013

It is called a Supermoon because this is a very noticeable alignment that at first glance would seem to have an effect.

The Moon’s distance from Earth varies because it follows an elliptical orbit rather than a circular one.

2013 year the Supermoon is up to 14 per cent larger and 30 per cent brighter than a typical Full Moon is.

Reason for supermoon formation:

This is a result of the Moon reaching its perigee -- the closest that it gets to the Earth during the course of its orbit. During perigee, the Moon is about 356,992 km away, as compared to the 405,696 km away that it is at its furthest distance from the Earth (apogee).

Impact of Supermoon on Earth:

The effects on Earth from a supermoon are minor, and according to the most detailed studies by terrestrial seismologists and volcanologists, the combination of the Moon being at its closest to Earth in its orbit, and being in its ’full moon’ configuration (relative to the Earth and Sun), should not affect the internal energy balance of the Earth. Scientists have dismissed notions that the phenomenon could cause bizarre behaviour or natural disasters. Its most significant impact is likely to be on the tide. Experts say the next ‘supermoon’ is expected to appear in August 2014.

Major Disasters in India

Major Disasters in India

Management of Disasters in India

DISASTERS AFFECT almost every part of the world. According to a World Bank report titled “natural hazards, unnatural disasters,” floods and storms are the most widespread while droughts are prevalent more often in Africa. Regions which suffer from frequent droughts and floods are also home to most of the hungry in the world. Climate change is expected to exacerbate the situation. There is, therefore, a need to recognize hazards and vulnerability in a comprehensive manner and take effective steps for prevention, mitigation and management.

Management of Disasters in India

In the case of India, natural disasters like floods, cyclones and drought occur repeatedly in different parts of the country. Many districts of India are prone to multiple hazards and face different disasters around the year. Earthquake, hailstorms.

Growth of Communalism

Communalism is a belief that all those who have a common religion also have, as a result, common social, political, cultural and economic interests and identities. It is a notion that religion forms the base of the society and a basic unit of division and that it is religion which determines all other interests of its adherents.

The genesis of communalism in India can be found in the British conquest of India and its impact on the people. The British conquest marked the decline of upper class Muslims, particularly in Bengal where they lost their preeminence in employment in army, judiciary and administration. Slowly with the Permanent Settlement of 1793 along with the making of English the official court language in 1833 the upper class Muslims began to lose their power and influence. In the Indian situation, the loss of Muslims was the gain of Hindus as they had responded more positively to education and other modernizing forces.
