The significance of record can be measured by the fact that Mumbai Metro Rail took about seven years to complete 11 km of metro viaduct; Bangalore and Chennai took over five years to complete about 25 km of viaduct each. Delhi took more than three years to achieve the same.

City’s ongoing elevated metro project has created a construction record by completing 27 kilometres of metro viaduct in just 20 months.

While the first between two pillars was erected near Genpact in Habsiguda in December 2012, the 1,000th was done on Sunday near S.R.Nagar bus stop, thus completing 38 per cent of viaduct works.

A total of 2,665 spans are required for 72 km of viaduct spread over three corridors: Miyapur to L.B.Nagar, JBS to Falaknuma and Nagole to Shilparamam/Raidurg.

The significance of record can be measured by the fact that Mumbai Metro Rail took about seven years to complete 11 km of metro viaduct; Bangalore and Chennai took over five years to complete about 25 km of viaduct each. Delhi took more than three years to achieve the same.

Engineering feat

HMR’s engineering feat of fast construction in congested roads of Hyderabad with a good safety record was possible due to a number of proactive measures taken by the State Government and the engineering capabilities of L&T, said Managing Director N.V.S. Reddy.

As on date 1,473 foundations (56 per cent), 1,370 pillars (52 per cent) are completed.

The Government too had facilitated setting up of the country’s two biggest precast yards, one at Uppal in 70 acres and another one at Qutbullahpur in 62 acres where L&T Metro Rail Hyderabad had established factory-like precast yards with sophisticated machinery such as automatic steel cutting and bending machines to produce precast segments each weighing about 40 tons, he said.

Precast segments are being transported in the night on low-bedded trolleys to various metro construction sites and erected between metro pillars with the help of “launching girders”. In all, 15 launching girders are being used to carry out these erection works simultaneously at several spots.

General length between two pillars is 100 feet, bridged by 11 precast segments. They are then glued and tied with a bunch of iron strands from inside, elongated and permanently grouted. The viaduct spans can withstand heavy loads plus heavy gales or earthquakes.

CM’s pat for HMR

Meanwhile, Chief Minister K. Chandrasekhar Rao congratulated HMR & L&TMRH engineers for the achievement on being informed by the MD.

Delicate surgery performed

Neurosurgeons at Star Hospitals successfully performed a surgical procedure on a 40-year-old patient Vishnuvardhan Varma who had lumbar disc disease, a condition where the disc of the spinal region causes low back pain, and during the entire procedure the patient was awake and aware.

Post surgery, the patient was able to walk without any pain, surgeons said. The patient was admitted to the hospital with lower back pain and pain radiating down the left leg, up to his ankle.

Investigations later revealed that Mr. Varma had a disc problem at the lumbar region (lower spine area) that was putting a lot of pressure on one of the nerves, hospital authorities said.

“We did a minimally invasive surgery. There was no scar, damage to muscles or bones.

The risk of general anaesthesia was avoided because the patient was awake.

Unlike in the convention surgical procedure, in which patients take six weeks to recover, the recovery by this procedure is fast and patients can get back to their routine quickly,” said Dr. Sai Sudarsan and Dr. Sukumar Sura, the minimally-invasive endoscopic neurosurgeons at Star Hospitals.

The alluring waters of Gandipet

One of the most lasting legacies of the Deccan has been the water management policy formulated by the Kakatiya dynasty, which relied mainly on small tanks for its irrigation and drinking water requirements. There was a time when the Telangana countryside boasted of thousands of tanks which ensured a perennial supply of water for settlements across the region. The Qutub Shahi rulers continued the practice by adding numerous tanks of their own, especially in the areas abutting the citadel at Golconda. A majority of those tanks continued to serve the population till post-reorganisation exploitation of the region’s resources led to their being either rendered dry or unusable due to pollution.

Following the great floods of 1908, Mahboob Ali Khan, the then Nizam of Hyderabad, sought long-term and effective solutions to the perennial inundation brought on by a recalcitrant Musi. Initiating the process of ‘improvement’ with a search for the right person to handle the future planning of Hyderabad, the Nizam refused the recommendations of Lord Curzon in offering the services of Sir Michel Esthesol, director general of irrigation, Government of India. Ignoring the availability of T D Mackenzie, chief engineer of the Nizam’s Dominions, he chose the native expert Sir M Visvesvarayya for the job. This was not just a pointed snub at the British, who had already antagonized the Nizam with their unreasonable attitude in dealing with the state, but an informed decision if one takes into account the renowned engineer’s role in influencing policy at the irrigation commission. Visvesvarayya’s ingenious flood control proposal for Hyderabad led to the creation of Osman Sagar and Himayat Sagar, the two ‘balancing tanks’ located upstream of the city. The twin reservoirs, based on the Kakatiya model, served the dual purpose of taming the Musi and at the same time providing an assured water supply to the city.

It is said that 16 villages were submerged to create this sprawling lake, which once spread over 45 square kilometres. The painful displacement of ancient settlements was, however, amply justified by the immediately-apparent benefits of the scheme. Foremost among these was the delivery of safe potable drinking water directly to homes.

Popularly known as Gandipet, Osman Sagar has found a unique place in the hearts of a grateful public, who swear by the curative properties of its waters. It is claimed that the Gandipet waters provide a panacea for almost all known ailments. No wonder then that Gandipet ka Pani, along with the equally notorious Hyderabadi Biryani, has been traditionally blamed for luring visitors into settling down in the city once they acquire a taste for these two cherished commodities.

Understandably, the Nizam Mir Osman Ali Khan remained ever suspicious of Gandipet water, refusing to drink even a single drop from the reservoir named after him! This abhorrence is generally believed to have stemmed from an ingrained preference for the waters of Bam Rukn-ud Dowla, the traditional source of drinking water for Hyderabadi Royalty. The fact that the Nizam never let his personal preferences stand in the way of progress is abundantly manifest in the fact that King Kothi remained unconnected to the state-of-the-art water supply and sewerage network that was commissioned for the city. There is a popular belief that this resolute stand against modernisation arose due to an assurance given by the Nizam to his palace staff that change would not deprive them of their jobs.

Hyderabad was once famous for its gardens and the suburbs of the city were referred to as the ‘Baghaat’ or Garden district. However, by the time of the 1908 floods, most of the historic water bodies in the city and its periphery had been commandeered to cater to the drinking water requirements and minor cultivation needs. The lush gardens of Hyderabad were but a distant memory. With the two major reservoirs providing for the water needs of the city, older water bodies were free to cater to parks and gardens proposed under the city improvement scheme. In certain areas, lakebeds were to be drained and reused as open spaces and parks. Though the implementation of CIB proposals was abandoned post re-organisation, the Hussainsagar continued to irrigate the gardens of Osmania University and downstream localities till industrial effluents rendered it into a cesspool.

The proposal of the Telangana government in favour of protecting lakes is a welcome move and signals a return to the maliciously abandoned schemes of the CIB. Emulating the Kakatiyan legacy bore fruit during the Asaf Jahi period, especially during the reigns of the last two Nizams. Revisiting Visvesvarayya’s proposals and reverting to traditional water management systems will undoubtedly prove to be immensely beneficial for Telangana.

More doctors for Telangana hospitals

DoctorsTELAN05jul2014

Counselling being conducted for giving postings to 124 in-service doctors. Ninety-eight of the in-service doctors opted for Telangana Vaidya Vidhana Parishad hospitals.

In one of the first appointments taken up by the government after the formation of Telangana, the medical authorities on Friday conducted counselling for giving postings to 124 in-service doctors who recently completed their postgraduate courses in different specialisations.

The counselling at the auditorium of Directorate of Medical Education was confined to clinical duties in gynaecology, paediatrics, general medicine, anaesthesia, ophthalmology, dermatology and pharmacology. Ninety-eight of the in-service doctors opted for Telangana Vaidya Vidhana Parishad hospitals and twenty others for Directorate of Public Health institutions in the State, including primary health centres. There were six absentees.

On Saturday, counselling will be held for non-clinical posts. The doctors will be re-designated as Civil Assistant Surgeons (Specialist) after they resume duty. The counselling on Friday witnessed the obstruction of a woman doctor from Visakhapatnam, A. Kavitha, by members of Telangana Doctors’ Association on the ground that she belonged to Andhra Pradesh. Dr. Kavitha was issued “order to serve” in Telangana by the Central government, applying the 52:48 principle of distribution of officers between the two States.

But the association members refused to allow her posting which forced counsellors to look for an alternative candidate. However, Dr. Kavitha was later posted to a hospital in Hyderabad after she protested that her service would be terminated if she did not have a job in either State.

The shutdown of power added to the confusion. The Director of Public Health, Champa Naik, was present.

Hyderabad-raised researcher finds new way to teach robots

Hyderabad:

We know robots are the future. But humanoids take a lot of time learning to do their tasks. Hyderabad-raised researcher Dr Rajesh P.N. Rao and his team has found a novel way of teaching robots using crowd sourcing technology. They say robots can just go online and find hints from hundreds of people to do their tasks by themselves without having to teach them with painstaking long commands.

In a first, University of Washington associate professor Dr Rajesh P.N. Rao and his team had demonstrated the first brain to brain interaction through the Internet in which one person would imagine an action and another ‘online’ would replicate the imagined action. Working on robots, Dr Rao, who studied in Hyderabad till the age of 18, says humanoids could one day proliferate in our environment.

But robots are now designed to do a particular task or a set of them. They have to be programmed to teach them how to go about a job. Robots learn by imitating humans, but it could take many lessons for it to hold a dish perfectly or place the book at the right place.

But Dr Rajesh Rao’s team has proposed using crowd sourcing techniques where robots can, all by themselves, go online, and ask for advice “Robots in the not-so-distant future will be in our homes, offices, and other human environments. We will want them to learn new skills on-the-job so that they can get better at helping us” Dr Rajesh Rao said.

“Our research demonstrates that robots can go online, and hire human helpers whenever they are stuck and get hundreds of hints and suggestions from humans all around the world,” he further said.
Crowd sourcing is the process of soliciting information from a large online community. “This is a way to go beyond just one-on-one interaction between a human and a robot by also learning from other humans around the world,” Dr Rajesh said.

However, there could be problems if some spammers in the online community feed wrong information to the robot. “There were some spammers who produced repeated data from multiple accounts, and even others who produced data without following instructions. We are planning to adopt more complex quality control techniques to improve the quality of crowd sourced data in future,” researchers said.
