One of India’s most prestigious building, The Parliament House is not safe from fire. It’s been nearly a decade now that the 12 acre complex is functioning without a fire safety certificate, reported english news channel NDTV.
In less than two weeks time, the building has seen two fires, the latest on Sunday, when insulation material next to the air conditioner unit caught fire during its maintenance.work.
“The fact is that this is an old building and even the wiring may be old, we are checking to make sure that it is safe and whatever requirements are needed to get the fire approval can be obtained,” Mukhtar Abbas Naqvi, the Minister of State for Parliamentary Affairs, told the channel.
The Delhi Fire Service carried out an inspection in August 2013 and recommended corrective measures to the Lok Sabha Secretariat.
The fire department had asked for the installation of sprinklers, modification of emergency exits and rewiring of cables. But none of these measures has been taking so far, and the Parliament House is functioning without a mandatory safety clearance
Mumbai, October 8, 2017 : A government-appointed panel for revising India’s Haj policy has recommended abolishing subsidy for the annual Muslim pilgrimage to Mekkah and Medina in Saudi Arabia besides allowing women devotees aged over 45 to travel in a group of at least four without a male relative.
The proposed Haj Policy 2018-22, submitted to Union Minister for Minority Affairs Mukhtar Abbas Naqvi, has been drafted in light of a 2012 Supreme Court direction to gradually reduce and completely remove the subsidy by 2022.
“It is advisable that the existing reduction plan (phasing out of subsidy) be followed,” according to the recommendations.
In a major reform, the draft Haj policy proposes to partially quash an earlier rule that barred women Haj aspirants to travel without ‘mehram’, a close family member like husband, father or brother.
“Ladies above 45 years of age be allowed in a group of four or more to go for Haj without a mehram,” the panel recommended.
Women below 45, however, will have to be accompanied by a male family member, according to the draft Haj policy that proposes to increase the quota for mehrams from 200 to 500.
Among other recommendations, made by the panel headed by former secretary Afzal Amanullah, are bringing down the number of embarkation points from which pilgrims can take flights to Saudi Arabia from the present 21 to nine.
The embarkation points for Haj pilgrims from next year would be New Delhi, Mumbai, Chennai, Kolkata, Bengaluru, Hyderabad, Lucknow, Kochi and Ahmedabad.
The distribution of quota between Haj Committee of India and private tour operators will be in the ratio of 70:30 — almost a five percent hike for the private players.
This year, the Haj quota for India — home to the world’s third largest Muslim population — was increased to 170,025, of which 125,025 was allocated to the Haj committee and 45,000 to the privater tour operators.
On the long-pending proposal to revive Haj pilgrimage by ship, Naqvi said the Saudi government would be consulted and then it would float an expression of interest to guage the market for such travel.
Independent tour operators say travel by ship would drastically reduce the cost per pilgrim to around Rs 60,000, making it affordable to a larger section of the population.
Regarding the distribution of Haj quota among states and union territories, the panel has recommended that it should be in the ratio of the Muslim population and in proportion to the number of applications received from each state or union territory.
Special quota for Haj pilgrims from Jammu and Kashmir will be increased from existing 1,500 to 2,000.
The reserved category of applicants in the 70-plus age group and fourth-timers has been abolished and they would go through the normal lottery. (IANS)
The researchers described a process by which tiny diamonds curtail the electrochemical deposition called plating
We anticipate the first use of our proposed technology will be in less critical applications
Battery buildups called dendrites are one of the main causes of lithium battery malfunction
USA, August 28, 2017: Researchers have found that tiny diamonds (diamond particles 10,000 times smaller than the diameter of a hair) can prevent short-circuits and fires in lithium batteries widely used in various mobile devices from smartphones to laptops.
The new process that uses tiny diamonds can turn electrolyte solution – a key component of most batteries into a safeguard against the chemical process that leads to battery-related disasters.
In the study, published in the journal Nature Communications, the researchers described a process by which tiny diamonds curtail the electrochemical deposition, called plating, that can lead to hazardous short-circuiting of lithium ion batteries.
“We anticipate the first use of our proposed technology will be in less critical applications, not in cell phones or car batteries,” said Yury Gogotsi, Professor at Drexel University Philadelphia Pennsylvania, US.
“To ensure safety, additives to electrolytes, such as nano diamonds, need to be combined with other precautions, such as using non-flammable electrolytes, safer electrode materials and stronger separators,” Gogotsi added.
As batteries are used and charged, the electrochemical reaction results in the movement of ions between the two electrodes of a battery, which is the essence of an electrical current.
Over time, this re-positioning of ions can create tendril-like buildups almost like stalactites forming inside a cave.
These battery buildups, called dendrites, are one of the main causes of lithium battery malfunction.
As dendrites form inside the battery over time, they can reach the point where they push through the separator, a porous polymer film that prevents the positively charged part of a battery from touching the negatively charged part.
When the separator is breached, a short-circuit can occur, which can also lead to a fire since the electrolyte solution in most lithium-ion batteries is highly flammable.
To avoid dendrite formation and minimize the probability of fire, current battery designs include one electrode made of graphite filled with lithium instead of pure lithium.
The use of graphite as the host for lithium prevents the formation of dendrites. But lithium intercalated graphite also stores about 10 times less energy than pure lithium.
The new study showed that mixing nano diamonds into the electrolyte solution of a lithium ion battery slows dendrite formation to nil through 100 charge-discharge cycles.
The finding means that a great increase in energy storage is possible because dendrite formation can be eliminated in pure lithium electrodes.
The discovery is just the beginning of a process that could eventually see electrolyte additives, like nano diamonds, widely used to produce safe lithium batteries with a high energy density, Gogotsi noted. (IANS)
