The indigenously built by DRDO, the 2000 km plus range missile, Agni – ll failed to deliver the desired results for the second time in six months. The indigenously developed inertial navigation system (INS) also failed. It is reported that imported INS used to work without fail. Why India is not in position to develop quality products? In any system used in space and defense activities quality control is at-most importance due to the stringent quality requirements of the equipments.
Why India can not even duplicate imported equipments/systems with good quality control? Quality is always compromised by the corrupt officials endangering the important multi-Crore missions. Chandrayan is another example of such failures. India can only beat China in quality because Chinese products are much inferior in quality.
Corruption in high places is the route cause of all failures/miseries suffered by industrial and technological sectors in India.

Global warming – Developed countries cornering India?
Some studies reported in Nature have indicated that the global warming will be stabilized at 2 degree Celsius above the “below pre-industrial era levels” if CO2 emissions are halved by 2050. The UN Panel of climate scientists has predicted that the average global temperature rising above the threshold of 2 degree will have catastrophic impact on the climate.
Is is understood that India has accepted this as the global limiting level at the Major Economies Forum meeting held recently in Italy. The rich countries which participated in the meeting also agreed to reduce the emissions by 7-14% below 1990 levels by 2030. It looks too small for the countries which have been polluting the environment with green-house gases for so long. The CO2 emission from US was 6.049 billion metric tonnes in 2004 with per capita of 20.4 metric tonnes! Compared to this, India’s emissions stood at 1.342 billion metric tonnes with per capita of 1.2 metric tonnes. China’s emissions were about 4 times higher than that of India.
A United Nations agency in one of the survey reports (2009) rightly pointed out that the industrialized nations should take deep emission cuts of the order of 40% below 1990 levels by 2030 and 80% cut by 2050. In a global carbon budget scenario, the share of industrialized countries should be of the order of 21%. Any consumption of the budget exceeding this by the developed countries would be at the cost of developing countries, which need industrialization in a big way in the coming years.
India should not or should not be made to accept any such discriminatory or legally binding proposals on emission-cut targets in the forthcoming United Nations Conference at Copenhagen in December this year. In support for the global concerns on climate change, India also should develop and employ emissions-free technologies in its future industrial developments.

Lead pollution world-wide – Alarming
Pollution from lead and other heavy metals are agents of disease for many of the world’s children. In poor countries, the health risks associated with this kind of pollution are all too often seen as the inevitable price of economic development.
Lead exposure is a major health hazard. It is a metal with no known biological benefit to humans. A direct link has been found between early exposure and extreme learning disability, hyperactivity, violence and lethargy. Too much lead in the body interferes with the normal development of the brain, the central nervous system, the kidney and the heart.
An estimated 120 million people worldwide are exposed to lead in the environment, in air, soil, water. It is estimates that over 12 million people are affected by lead contamination from processing of used lead acid batteries and unsafe unregulated recycling throughout the developing world. Dangerous lead contamination is found in children in some 80 countries.
Lead poisoning is determined by measuring the ratio of lead to blood in the human body. The accepted limit of lead in blood is 10 µg/dL.
To take the lead out of blood, a chemical called calcium di-sodium EDTA is injected into the body to form a complex (chelate) with the lead ions in the blood which ultimately passes out in urine and faeces. The concentrations, in such levels are measured using advanced testing equipment such as total reflection x-ray fluorescence unit and germanium photon detectors. International organizations such as IAEA support such activities.
