Indian origin doctors come together to battle COVID-19

Hundreds of doctors of Indian origin came together under the banner of Global Indian Physicians COVID-19 Collaborative on Saturday to share knowledge and foster cross-system learning in the fight against COVID-19.

Addressing the first virtual meeting of the collaborative, Prathap C. Reddy, chairman, Apollo Hospitals, and founder-president of the Global Association of Physicians of Indian Origin (GAPIO), said that the pandemic was unlike anything he has seen in his 65 years of practicing as a doctor.

Stressing on the need for collaboration by breaking all barriers, he said that the pandemic had made medical professionals realise their amazing ability to find solutions in record time.

Indian response

Vinod K. Paul, NITI Aayog member and co-chair of the Empowered Committee for COVID-19 Response in India, said that India’s response has been calibrated, graded, and it was yielding results.

On the availability of PPEs, he said that the present availability was adequate for the present situation and in a matter of two to three weeks, the availability of PPEs would be sufficient to cater to even worst-case and extreme scenarios.

He said that India was also focusing on developing vaccines for COVID-19, with four possible vaccine candidates being worked on in four of the country’s laboratories.

Sudhir Parikh, secretary general of GAPIO, expressed hope that convalescent plasma therapy would prove to be an effective treatment for COVID-19 and highlighted, in the American context, the need for creating a database of persons who had recovered from COVID-19, for plasma donation.

Patrice A. Harris, president, American Medical Association, highlighted the need for increased collaboration at international, national and local levels, and accurate data collection.

“For instance, the African-American population seemed to be disproportionately affected by the disease. However, we do not have data at the national level,” she said.

Kamlesh Khunti, director, Centre for Black and Minority Ethnic Health in the U.K., said that early data had indicated that South Asians and Black minorities were disproportionately affected by the disease in the U.K. as well.

Tamil Nadu techies assemble to give health workers much-needed shield to face COVID-19

Chennai :

On March 22, as the nation locked itself in observing the government-ordered Janta curfew, Coimbatore-based Ebin Ephrem Elavathingal, senior manager at AIC Raise, and his team — student start-up JK Data Systems incubated in AIC Raise, supported by Atal Innovation Mission, NITI Aayog and students of Rathinam Group of Institutions, Coimbatore — came up with an idea.

A version of face shields to protect the essential workers in the frontlines of the pandemic.

Now, three weeks later, with over one lakh shields distributed across the country, they’re not done just yet, creating a working prototype of an Intermittent Positive Pressure Breathing ventilator (IPPV).

The five-member team headed by Ebin and comprising the student start-ups by Karthik S, Gowtham Santhakumar and their team, with support of the Bio-Medical and Computer Science department of Rathinam College, are the people behind this ambitious project.

But despite their remarkable final model, you’d be surprised to find out that none of them has any prior experience with medical equipment.

“Once we started watching the global news and understanding the urgent need for ventilators in this pandemic, we immediately dropped what we were working on, and began to educate ourselves about ventilators through open source libraries and other resources,” says Ebin. Within a week, they already had their first prototype with basic features.

EbinCoimbatore02CF13apr2020

But keen on enhancing the model even further, the team re-engineered the design of an international open-source ventilator project to produce their second working prototype, with improved control facilities, within four days.

“We haven’t gotten an Indian Council of Medical Research (ICMR) license yet, but this device can monitor control of the tidal volume, breath per minute and inspiration expiration ratio adjustments. It is also enhanced with pressure, flow and oxygen monitoring systems,” he explains. With most of the country’s ICU ventilators costing over Rs 5 lakh, their simpler model comes in at just Rs 25,000, with the basic first prototype at RS 10,000.

Ready to take the next steps, Ebin assures us that they are currently at a production capacity of 100 ventilators a day.

Once they receive government approval, the team is ready to spring into action. “Our thoughts upon taking up this massive new project was to help save our nation. It’s as simple as that. I even quarantined myself at the office to ensure that we can truly build something of value,” says Ebin.

Still choosing not to rest on their laurels, the team is already brainstorming on their next project, something that could help in a post-coronavirus world. And while they’re hard at work on it, Ebin’s only plea — if you have the intellectual property to make a difference, now’s the time.

The team

App to map people with fever signs

The Greater Chennai Corporation has developed an app to geographically map people having fever, the most common symptom of COVID-19.

Chennai :

The Greater Chennai Corporation has developed an app to geographically map people having fever, the most common symptom of COVID-19. Touted as the first such technology to be used in any city in the country, the app, named as GCC Corona Monitoring, will mark people in home quarantine as well as the areas where crowd gathers against social distancing norms. The app developed by a team of volunteers from Mr Cooper will be officially launched within a week, confirmed official sources.

“Currently, most of the urban civic bodies in the country are actively monitoring only people under home quarantine. But, there could also be a cluster of people with fever symptoms in a particular area. Since most people are staying indoors, nobody knows if the person next door is having fever. This can lead to community spread,” said M P Azhagu Pandia Raja, a research fellow with Ministry of Housing and Urban Affairs, who conceptualised the app for Greater Chennai Corporation.

How it works?
1) Click on the option in app
2) Photo of house for location
3) As more people notify fever symptoms, officials can identify clusters and send health workers

Home-quarantined people
1) App geo-tags people
2) Will help civic body to channelise more resources
3) Over 1,000 have downloaded the app and marked themselves

Notifying about crowds
There is an option to notify the civic body about crowd in an area. Anyone can click the picture of a group and send it through the app

Where to get it?
Since Playstore is taking down apps related to COVID to stop spread of fake news, it will be released on GCC’s website

Indigenously designed, Tanker Arjun reports for duty

India’s most sophisticated, indigenously designed battle tank, Arjun Mk-1A, has cleared all trials and is ready to go into production.

Chennai :

It’s the most lethal, sophisticated and all-weather battle tank that India has indigenously designed and conceptualised till date. Meet Arjun Mk-1A main battle tank, a 68-tonne rugged bull, waiting to join the Indian army. It will be a star attraction at the DefExpo India 2020 to be held in Lucknow in February.

Armoured Corps cleared the tank after successful completion of final integration tests conducted earlier this year in the western sector of Rajasthan. Arjun Mk-1A is an improved variant of Arjun Mk-1, whose two regiments (124 tanks) are in service.

Scientists of Chennai-based Combat Vehicles Research and Development Establishment (CVRDE), a Defence Research and Development Organisation (DRDO) lab, are the architects of this improved avatar of Arjun. The Heavy Vehicles Factory in Avadi is expected to commence production after receiving the order.

Top DRDO officials confirmed the new variant of Arjun had passed the rigorous army evaluation. “The tank has fulfilled all user specifications and undergone elaborate field trials. We expect the order of intent any time soon.” Officials said 72 improvements were made to Arjun MBT Mk-1A, of which 14 were major upgrades specifically requested by the army.

CVRDE Director V Balamurugan said the fundamental parameters of a battle tank are “fire power, protection and mobility”. Arjun MBT Mk-1A is improved on all these fronts.

Four upgrades were made to firepower. An improved Gunner’s Main Sight (GMS) integrated with Automatic Target Tracking (ATT) was fitted. This helps the crew track moving targets automatically, making it easy for the gunner to fire even when the tank is moving. The Commander’s Panoramic Sight (CPS Mk II) was integrated with Thermal Imager that enables the commander to effectively conduct surveillance in both day and night through eye-safe Laser Range Finder with advanced Hunter Killer Capability. Besides, additional varieties of ammunition were incorporated to enhance the lethality of the battle tank. Other than conventional Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS) and High Explosive Squash Head (HESH) ammunition, Thermo Baric (TB) and Penetration Cum Blast (PCB) ammunition were developed.

Lastly, the vehicle was upgraded with a Remote Controlled Weapon Station that provides the loader capability of engaging ground and aerial targets from the protective envelop of the tank armour. It provides an additional capability to fight in urban areas called Hatch-closed firing.

Extra protection for crew

The battle tank will have a crew of a commander, gunner, loader and driver. Keeping them out of harm’s way is paramount. For this, Arjun Mk-1A comes with a slew of new features. Balamurugan said Track Width Mine Plough (TWMP) is a significant addition, which provides capability for the tank to easily cross minefields as the plough mounted to the front creates a mine-free path by tossing mines to the sides of the tank. The Explosive Reactive Armour (ERA) panels are provided for effective protection against ever-evolving anti-tank threats like shoulder-fired anti-tank grenades and missiles. These were mounted along the frontal arc of the hull and turret.

Another new feature is a Containerised Ammunition Bin with Individual Shutter (CABIS) that provides enhanced protection to the crew from inadvertent burning of ammunition stored in the ready round bin. Hot gas generated by ammunition burning is vented out by blow-off panels from the roof of the turret.
Besides, Arjun Mk-1A has protection against chemical attacks. A special chemical sensor is mounted to detect the presence of harmful toxic chemicals around the tank. “The sensor detects harmful chemicals, triggers an alarm and the Nuclear Chemical warfare system increases the pressure in the tank compartment to a level higher than in the atmosphere outside preventing toxic air from entering. The crew gets air through a particulate filter,” officials said.

The Roof Mounted Driver’s Seat protects the driver from shocks and enhances driving comfort. Other upgrades include a Laser Warning and Counter Measure System that protects the crew by creating a smokescreen between itself and the enemy and Anti Infra Red/Anti Thermal Imaging paints that reduce the tank’s signature when viewed through IR/TI cameras or goggles making it difficult for enemies to detect.

Mobility-related improvements

Officials said one of the challenges in making of Arjun MBT Mk-1A was the overall weight. Every improvement comes with baggage, which the user may not like as it may compromise mobility. To counter added weight, an Advanced Running Gear System was developed where the hydro-pneumatic suspension system was redesigned to enhance the tank’s agility. Tweaking the final drive also ensured the required agility.

An Advanced Land Navigation System was added to provide enhanced navigation capability in desert terrains during war. It provides accurate information of where the tank is using Inertial Navigation or GPS or both and where the tank needs to go in the absence of any signage in the war theater. An uncooled  Night Vision camera for the driver has been provided. The obsolete Image Intensifier for the driver has been replaced with un-cooled Thermal imager with binocular sights, providing him with a capability to travel at reasonable speeds even in pitch-dark conditions.

‘Sanitary napkin at Rs 3/piece’: TN NGO helps poor women get access to pads, creates jobs

Padman may have become a household name owing to his single-minded crusade to make sanitary napkins accessible to women across all range of the socio-economic spectrum.

Erode :

Padman may have become a household name owing to his single-minded crusade to make sanitary napkins accessible to women across all range of the socio-economic spectrum. However, in his own state are many villages, where neither padman nor a sanitary napkin is known. This is an anomaly Rights Education and Development Center (READ) NGO has undertaken to set right.

In collaboration with women self-help groups (SHGs), READ set up 10 pad-making units at 10 villages at Sathyamangalam and Gobichettipalayam, TN Palayam blocks of Erode. Now, these women have access to pads at Rs 3 per piece and Rs 30 per packet of 10 pads. The added benefit is jobs for 100 women.

READ NGO Director Karuppusamy told Express, “Even today many women use cloths in tribal hamlets and villages in Erode. When we enquired about the reason, they pointed out two factors — affordability and lack of awareness on the importance of using sanitary pads. So we decided to pool funds and develop a social enterprise model to manufacture sanitary napkins at a subsidised cost.” A few of them were inaugurated earlier this week, he added.

The NGO identified major places that require immediate intervention and did a pilot study to set up a pad manufacturing unit. To make it more effective, the NGO collaborated with the local women self-help groups (SHGs) and directed them to take over the social enterprise. There are ten members in each SHGs and the work is equally divided among them — one group takes care of production and another does marketing. The units are registered under the Ministry of Micro, Small & Medium Enterprises under the brand name ‘Feel Free’.

One member of an SHG at Polavakaliyampalam in Gobichettipayalam, Nirmala, said, “Our motive is to make women in our region aware of sanitary pads. We go to every house, schools and colleges and talk about its significance. We do not just sell the pads but also teach them everything from using them, the time period for which one pad can be used to the disposing methods.”

On an average one unit produces up to 200 pads a day. The units are set up on a 10*12 sq ft area and it cost Rs 4,20,000 to set up one unit. The machines were sourced from Uttarkhand.

“Since it is an automatic machine, work is easy and quick. We need to place the cotton tissue sheets in the machine, which converts them into a series of pads. The organic winged napkins are made of cloth, wood-pulp cotton. All the pads are sterilized using ultraviolet radiation before packaging,” she added.
