Century-old Rly Workshop May Shut Soon

Vellore :

The century-old engineering workshop of Southern Railway at Arakkonam, which played a crucial role in building the country’s first sea bridge (Pamban Railway Bridge), is on the verge of closure due to shortage of manpower.

Established in 1905, the workshop played a vital role in the construction of major railway bridges, including the railway bridges in Kerala, Karnataka and Andhra Pradesh, which come under the Southern Railway.

Among the workshop’s main products are welded type girders, riveted type girders, steel channel sleepers, dip lorry, push trolley, points and crossings assemblies, passenger platform shelters and foot over-bridges. Ten years ago, around 4,000 employees worked at various units of the workshop. Today, the workforce has reduced to less than 800. About 80 per cent retired over the years.

Sources said officials surrendered the vacant posts without filling them. One year ago, 30 were recruited through Railway Recruitment Board. But every year, at least 100 persons were retiring from service. “If this situation continues, the workforce will be reduced tremendously to less than 300 in the next three to four years,” an employee, who is also nearing retirement, said. In the next six to seven years, only 50 employees will be left, he added.

Employees said vacant posts were not filled intentionally in a bid to shut down the workshop. The workshop has been manufacturing components to build bridges, tracks, signals, crossings, switches, trolley, inter-loading wagons, moulding and casting of wheels.

Employees said the foundry shop of the workshop had already been closed and many other units were likely to be closed in the near future. The source said there were many employees in group-C category that comprises supervisors, while group-D category had fewer employees. Some employees, who were part of the labour unions, were not working properly, said a Railway staff.

Chennai’s oldest telephone line is ringing loud at 100

Chennai :

When Oriental Telephone Company Ltd of England started telephone services in a few Indian cities at the turn of the last century, only a few privileged citizens of Madras had a telephone. One of them continues to ring, at the Indian Commerce and Industries Co Pvt Ltd in Broadway.

The building where the company is located.
The building where the company is located.

The Beehive Foundry, established in 1907 as the flagship company of the Beehive Kowtha Group, received the connection in 1915.

Indian Commerce and Industries took over Beehive Foundry in 1924 and acquired the historic line with the purchase. Indian Commerce and Industries director Ramesh C Kumar, the fourth generation head of the company, retains the connection and intends to keep it in the family.

“Our first and currently working telephone line completed 99 years on July 11, 2014 and has entered the 100th year of service. It is a proud moment for us as a company and as a family,” said Ramesh, who BSNL felicitated on Wednesday as the owner of the oldest existing telephone line in Chennai.

The telephone number has changed so many times over the decades that it’s uncertain what it was to start out with, apart from the fact that it was a three digit number — and that the address of the connection remains Beehive Building, No 57 (Old No 29), Prakasam Road, Broadway, Chennai – 600 108.

“We first had a three-digit number, which changed to 2020 in 1952. It later changed to 21071,” Ramesh said. “With the introduction of Kalmandapam Telephone Exchange, our line shifted to the new exchange and it allotted us the number 555021. When the Harbour Telephone Exchange opened, the line shifted again and the number changed to 512221.”

When telephone subscribers had to adopt seven digit numbers, it changed to 5231477. Finally, when BSNL allotted eight digit numbers in metros in 2002, it became 25231477 and has remained the same till today.

Oriental Telephone — which was set up on January 25, 1881 under an agreement between Thomas Edison, Alexander Graham Bell, the Oriental Bell Telephone Company of New York and the Anglo-Indian Telephone Company Ltd — installed the telephone line on July 11, 1915.

“Our line was under Madras Telephones Company, which took over Oriental Telephone in 1923,” Ramesh said. “We had the billing address changed to include the name of our parent company only in the early 1990s.”

For Ramesh, the telephone line is a piece of history. “This is probably the oldest telephone line in the country,” he said. “It is an heirloom.”

Teen invents device to avert road accidents

Trichy :

The death of a close relative in a road accident has prompted a 13-year-old student in the Nilgiris to invent a device he claims can alert drowsy drivers and help avert accidents.

The ‘Eye Blink Infrared Sensor’, the result of a year’s efforts by M Gokul, provided the class 8 student of the municipal middle school at RK Puram in Ooty, a chance to participate in the state-level exhibition for INSPIRE Award conducted by the Union government’s department of science and technology, Tamil Nadu science and technology centre and Shivani College of Engineering and Technology, Trichy on Saturday.

The device is aimed at preventing accidents due to the drowsiness of the drivers of all vehicles, including two-wheelers. The infrared sensor is designed to sense the blinking of the eyelids. If the lids remain idle for a few seconds, the sensor will pass a signal through a pic micro controller to the vibrator under the driver’s seat. The activated vibrator will shake the seat, jolting the driver awake.

“It was the death of my uncle P Kumar, a government bus driver, which kindled my innovation to design a device to avoid accidents. He met with the accident as he slept while driving the bus. The accident forced me to think that no one should die due to the drowsiness of the driver,” Gokul told ToI. He said he had been working on the device after class hours.

The signal will also stop the engine and make the vehicle come to halt gradually. L Sundaram, the science teacher who supported Gokul in his project, said they were making efforts to test the device in vehicles with the government’s help. “It is not costly and can be used in all vehicles. We need support from the government to take it to the next level,” he said.

Gokul’s father A Mani, a tea agent, is proud of his younger son. “When he expressed his thoughts to invent a device, I wholeheartedly supported him.

His continuous efforts have helped him create such a device. I will encourage him to go on in his career,” said Mani, whose elder son also won a competition at the INSPIRE programme in Chennai.

Chennai:

While Chennai is keeping close watch on passengers arriving from  Ebola affected countries at the airport, the country could have additional expertise to rely on as the first batch of seven officers from across India who underwent two-year training in ‘Epidemic Intelligence Services’ (EIS) at the Centre for Disease Control and Prevention in the  USA will be returning next month.

The Union government had entered into an agreement with the USA in 2010  for a training programme to be conducted by its Centre for Disease Control and Prevention (CDC),  Department of Health and Human Services, in coordination with  National Centre for Disease Control (NCDC), Ministry of Health, India.

Dr R. Mohan Kumar from Chennai, who was the only candidate from southern states to undergo the programme, says it included training in preventing a disease outbreak, identifying it at inception and in ways and means of handling  an outbreak should it hit a region.

While the second batch of 15 candidates undergoing the course has no representative from Tamil Nadu,the third batch, which will begin training in October will  include Dr Sri Kalpana, medical officer at the Institute of Public Health in Poonamallee.

Meanwhile, director of public health Dr K Kulandaisamy says it is important for the country to adopt a system to monitor and prevent the outbreak and spread of epidemics as global travel exposes many people to a wide range of health conditions today.  “Most of the new diseases spread globally through passengers. And so it is important to identify those coming from or returning to   epidemic affected countries  and keep them under medical observation,” he stresses. //

Jaw can be reconstructed with abdominal fat, says expert

Dr. S.M. Balaji (Photo: DC)
Dr. S.M. Balaji (Photo: DC)

Chennai:

Many of his surgeries are first-of-its kind and he is the doctor who introduced the latest technological advancements in reconstruction of facial defects to the city.

Director of Balaji Dental and Craniofacial Hospital at Teynampet and famous facio-maxillary surgeon Dr S.M. Balaji, says more specialists are needed in this particular field. Noted for making a great difference to the confidence and life of his patients, Dr Balaji is known for some of the most dynamic innovations in his field of specialty. In an interview to Deccan Chronicle, Dr Balaji explains how patients with jaw defects can expect to be completely normal people after surgery.

Excerpts from the interview:
Q) You are a pioneer in applying latest technology of tissue engineering. Can you explain the recent developments in the field?
A) Earlier, we used to remove the tumour of the jaw and take the bone from the hip or the leg and do a microvascular surgery for reconstruction of the jaw. It used to be a long procedure as it would go on for 10-12 hours. Also, anaesthesia is prolonged and the scar is so visible in the leg.
Now you can take the abdominal fat to reconstruct the jaw. Adipose stem cells present in the fat have inherent ability to grow into other tissues like bone, cartilage and tendons. People do liposuction and throw away the fat but it can be utilised. Since this technique is new, so far only three patients have undergone the reconstruction using abdominal fat.
Q) What kinds of defects are seen?
A) If somebody meets with an accident, a part of the bone, say, in the upper jaw, is lost and reconstruction is needed.
In case of oral cancer, after the cancer treatment, the person has to undergo reconstruction, otherwise there will be disfigurement. Given the incidence of oral cancer, more specialists are required in this field and the cost of reconstruction is affordable.
Reconstruction of facial defects has evolved over the recent years due to latest technological advancements. Craniofacial defects, be they congenital (by birth) or acquired (by accidents) or removal of tumour or cysts, they could be successfully rehabilitated.
Q) Recently, you rehabilitated a one-year-old Maldivian child with a rare type of facial bone disorder. Please explain.
A) He was born with a disorder in which the jaw bones are destroyed and gradually replaced by fibrous tissue which would cause difficulties in eating, speaking and disfigured appearance. His jaw tumour was entirely removed through the mouth without any scar in the facial region.
Using rhBMP-2 and titanium plate we reengineered the jaw bone and six months later, we could see a good amount of normal bone jaw formation and the boy was given fixed dental implants to replace his missing teeth. For the first time in the world, a rare type of jaw bone disorder was rehabilitated completely.
Q) What is rhBMP-2 and explain its benefits.
A) Recombinant human bone morphogenetic protein-2 is a biotechnologically engineered version of a protein that is otherwise normally found in the human bone.
Yes, this miracle protein stimulates the body’s own cells to convert into bone forming cells. Such cells lay down new bone at the site where the protein is placed.
By using this technology, the second additional surgery for grafting bone from the hip or rib to close the defect is entirely avoided. This technique is a boon in cases for closure of bone defects, such as alveolar cleft, a common birth defect (gap in the teeth-bearing region of the jaw).
Distraction osteogenesis is another revolutionary new technology that besides lengthening the bone, associated structures such as skin, soft tissues, nerves and blood vessels are also created.
In cases that require extensive removal of jaw bone in case of tumour or cysts, the residual jaw defect is reconstructed using plate-guided transport distraction osteogenesis that enables growth of new bone and soft tissues along the customised plate in accordance with each patient.

Tamil Nadu farmers reap rich dividends through watershed projects

Recreating water bodies, improved farming techniques yield better income

CHENNAI, AUGUST 15:

When the National Agro Foundation, a brainchild of the late C Subramaniam, the architect of India’s green revolution, set about sharing agro technology upgrades with farmers in Kanchipuram district near Chennai in 2003, their response was: All this is fine, but where is the water?

“This set us thinking. Kanchipuram was once known as the district of lakes, and gets an annual rainfall of 1,000 mm, but concentrated in two months,” says MR Ramasubramanian, Executive Director of the Foundation.

A double whammy was that along with the rainwater runoff, the rich top soil was washed away each year. An investigation with remote sensing maps and discussion with village elders revealed that numerous water bodies — tanks, ponds, wells etc had all disappeared over the years. So the Foundation, along with NABARD, launched a project to recreate water bodies through four watershed projects on 5,400 hectares at a cost of ₹4.62 crore.

The community was involved in repair and renovation, better use of water, modern farming techniques, resulting in better incomes and increased cropping cycles.

Crop cycles

Most of the farmers have small to medium landholding (2-3 hectares), and the project helped them move from one cropping cycle to two, sometimes even three, and profits went up by ₹20,000-40,000 per acre a year, says SV Murugan, Joint Director in charge of the project. The more enterprising ones, such as Nallamuthu, an IT graduate, went in for floriculture and horticulture and earned over ₹7 lakh.

Though planned in 2007, on a 50:50 basis between NABARD and the Tamil Nadu Government, grant of funds has been delayed, and work on only 1,000 hectares has been completed.

When work on the watershed programme began, both on farm as well as common land, all the land looked flat as the uncared for water bodies had filled up with soil and silt. Those renovated or recreated are now able to hold over one lakh litres of water; and one particular tank 7 lakh litres.

Apart from percolation ponds, groundwater recharge, water absorption trenches, supply channels were created or repaired, as also bunds, and water bodies linked to enable water to flow from one tank to another, one village to another; in one case 20 villages were thus linked.

Peak summer 

“Based on land ingredient and slope we do different kinds of bunding so that natural harvesting of rainwater takes place,” says Ramasubramaniam, recalling the Tamil adage: “Running water should be made to walk and walking water to sit.”

With the water table going up, “in peak summer months the wells are filled to the top. The last two years have seen deficient rainfall but farmers have managed well,” says Murugan.

The green cover in the entire area has gone up, top soil is conserved, resulting in farmers getting additional income. “Once water is conserved and used optimally, next comes technology, nutritional security for women through kitchen gardens, and then upgrades in value through organic cultivation. We ask farmers to reduce agro chemicals and use them only as supplements where necessary,” says SS Rajsekar, Managing Trustee.

The biggest benefit is that 280 acres of underutilised land has now been made fertile and brought under cultivation, he adds. “Also, the children of educated people like Nallamuthu will be enthused to stay in agriculture and not leave it for jobs in cities. And, such projects are the first steps towards the linking of rivers,” adds Rajsekar.

Picture for representation purpose

Krishnagiri:

A class 10 student from remote Krishnagiri district conceived an “artificial, imaginary” planet where human beings can live, and won a free trip to the National Aeronautics Space Administration in the United States. Kiruthika, the 14-year-old girl, student of a private school in Hosur, came up with the idea of imaginary planet, ‘Aparana Basaraya’, named after the great astronomers of India, Aryabhatta and Bhaskaracharya.

The ‘Aparana Basaraya’ concept was sent as an entry for the space settlement design contest conducted annually by Nasa-Ames Research Centre for School Students. As many as 1,567 students in 18 countries, including Bulgaria, Canada, China, the Czech Republic, UAE, India, the United Kingdom and USA, sent in over 562 entries. Kiruthika’s entry did not make it to the top 10 in the contest but her idea recevied appreciation and she was offered a free trip to Nasa. Six students from Jalandhar in Punjab won the grand prize for conceiving ‘Vona’, a settlement in Mars.

“My passion is biology but I decided to take part in the competition after my neighbour informed me about it,” says Kiruthika. Her project is about an artificial planet which can be positioned in space. It is cylindrical at the bottom and doughnut-shaped at the top. Humans can occupy the cylindrical shaped bottom area and the doughnut-shaped area can be used by cattle and others. Oxygen, water and other essentials reache the planet through less expensive sources. The project failed to impress but the jury accepted the idea and gave Kiruthika a chance to visit
